Carcinosarcoma of the uterus is a rare gynaecological neoplasm, which is also known as malignant mixed mesodermal tumor. Traditionally this tumour has been regarded as a subtype of uterine sarcoma, and its origin remains controversial. The exact nature and prognosis was not clear in the past. It is believed that uterine carcinosarcoma have a Mullerian duct origin and have a capacity to differentiate into various mesenchymal and epithelial components. Regarding the histogensis, various theories have been given; of which 'conversion theory' was broadly accepted. Carcinosarcoma are mostly of monoclonal origin with the carcinomatous component being the driving force. This type of tumor is broadly divided into two groups, homologous and heterologous, depending on the characteristics of the stroma or mesenchymal components of endometrial tissue. It is more frequent in black women and postmenopausal women. Radiation is a possible etiological factor but the exact etiology is not known yet. However, tamoxifen may induce carcinogenesis in some patients. Its clinical feature is very similar to endometrial carcinoma i.e. postmenopausal vaginal bleeding, have a very aggressive behavior and a poor prognosis. This pelvic malignancy is treated by multimodality therapy including surgery, chemotherapy and radiotherapy. Here we are reviewing old concepts about the disease and modern understandings of the origin, classification, pathogenesis and recent advances in the treatment of the uterine carcinosarcoma.

Epigenetics is the study of heritable alterations in gene expression that are not accompanied by the corresponding change in DNA sequence. Three interlinked epigenetic processes regulate gene expression at the level of chromatin, namely DNA methylation, nucleosomal remodeling and histone covalent modifications. Post-translational modifications that occur on certain amino acid residues of the tails of histone proteins modify chromatin structure and form the basis for "histone code". The enzymes Histone Acetyl Transferase (HAT) and Histone Deacetylase (HDAC) control the level of acetylation of histones and thereby alter gene expression. In many cancers, the balance between HAT and HDAC is altered. HDAC enzymes are grouped into four different classes namely Class I (HDAC1, HDAC2, HDAC3, and HDAC8), Class II (HDAC4, HDAC5, HDAC6, HDAC7, HDAC9, and HDAC10), Class III HDAC and Class IV (HDAC11). Histone Deacetylase Inhibitors (HDACI) exert anticancer activity by promoting acetylation of histones as well as by promoting acetylation of non-histone protein substrates. The effects of HDACI on gene transcription are complex. They cause cell cycle arrest, inhibit DNA repair, induce apoptosis and acetylate non histone proteins causing downstream alterations in gene expression. HDACI are a diverse group of compounds, which vary in structure, biological activity, and specificity. In general, HDACIs contain a zinc-binding domain, a capping group, and a straight chain linker connecting the two. They are classified into four classes namely short chain fatty acids, hydroxamic acids, cyclic peptides and synthetic benzamides. This review describes the clinical utility of HDACI as monotherapy as well as combination therapy with other treatment modalities such as chemotherapy and radiotherapy. Adverse effects and shortcomings of treatment with HDACI are also discussed in detail.

Oral cancer is one of the most common cancers in India. It's also associated with poor survival rate. Early diagnosis is the only way of reducing the high morbidity and mortality associated with it. However, most often there is delay in its diagnosis. Several adjuncts have been developed to aid in the diagnosis of cancer in its pre-cancerous and early stage. Chemiluminescence is one of the newly developed adjuncts, which is still in its infancy. This article reviews chemiluminescence technique and its applications in oral cancer diagnosis.

Squamous cell carcinoma involving the oral cavity (OC) and oropharynx regions are a major cause of morbidity and mortality world-wide. The recent discovery of a strong association between human papilloma virus (HPV) infection and OC and oropharyngeal (OP) cancer has prompted world-wide research into the exact etiology and pathogenesis of these cancers in relation to the HPV. HPV-positive OC/OP cancers generally present at a relatively advanced stage (by virtue of cervical nodal involvement) and are more commonly seen in younger patients without significant exposure to alcohol or tobacco. These factors are implicated in prognosis, regardless of HPV association. In this article, we review the biology and epidemiology, risk factors, association, molecular analyses, treatment response and prognosis of HPV-related cancers. Role of HPV vaccination in HPV-related OC/OP cancers has also been discussed.

The habit of chewing betel nut has a long history of use. Betel nut and products derived from it are widely used as a masticatory product among various communities and in several countries across the world. Over a long period, several additives have been added to a simple betel nut preparation; thus, creating the betel quid (BQ) and encompassing chewing tobacco in the preparation. Betel nut has deleterious effects on oral soft tissues. Its effects on dental caries and periodontal diseases, two major oral diseases are less well-documented. Betel-induced lichenoid lesions mainly on buccal mucosa have been reported at quid retained sites. In chronic chewers, a condition called betel chewers mucosa is often found where the quid is placed. Betel nut chewing is implicated in oral submucous fibrosis (OSF) and its use along with tobacco can cause leukoplakia, both of which are potentially malignant in the oral cavity. Oral cancer often arises from such precancerous changes. Thus, public health measures to quit betel use are recommended to control disabling conditions such as OSF and oral cancer.

Breast cancer is one of the familiar diseases in women. Incidence and mortality due to cancer, particularly breast cancer has been increasing for last 50 years, even though there is a lacuna in the diagnosis of breast cancer at early stages. According to World Health Organization (WHO) 2012 reports, breast cancer is the leading cause of death in women, accounting 23% of all cancer deaths. In Asia, one in every three women faces the risk of breast cancer in their lifetime as per reports of WHO 2012. Here, the review is been focused on different breast cancer markers, that is, tissue markers (hormone receptors, human epidermal growth factor-2, urokinase plasminogen activator, plasminogen activator inhibitor, p53 and cathepsin D), genetic markers (BRAC1 and 2 and gene expression microarray technique, etc.), and serum markers (CA 15.3, BR 27.29, MCA, CA 549, carcinoembryonic antigen, oncoproteins, and cytokeratins) used in present diagnosis, but none of the mentioned markers can diagnose breast cancer at an early stage. There is a disquieting need for the identification of best diagnosing marker, which can be able to diagnose even in early stage of breast carcinogenesis.

PMID
:25313730
Epithelial-mesenchymal transition (EMT), a key developmental program has been shown to occur in wound healing, organ fibrosis and in the initiation of metastasis for cancer progression. EMT is a process that describes the development of motile, mesenchymal-like cells from non-motile parent epithelial cells. Plasticity of the cells enable significant changes in cell phenotypes and this process is governed by the interplay among different functional classes of regulatory molecules. The process typically involves the control of specific gene expression programs with distinct functional impacts on the behavior of cells. An important feature of cellular plasticity, EMT has in the recent times attracted broad interest in the field of cancer research, tumor invasion and metastases. A complete understanding of the molecular events of EMT and a search for novel molecular regulators is required for prospective targets for therapeutic interventions. This review summarizes the critical biomarkers of EMT in the head and neck cancers.

Marta Adamczyk, Magdalena Fundowicz
DOI
:10.4103/0973-1482.137909
PMID
:25313731
Background:
Stereotactic body radiation therapy (SBRT) is reported as a well-tolerated treatment modality, which offers a long-term tumor control.
Aims:
The aim of the following study is to present the place of proposed treatment preparation and its delivery for liver metastases with conventional linear accelerator among reported SBRT protocols.
Materials and Methods:
We present our treatment preparation, planning and set-up verification procedure performed for liver metastasis. The prescription dose of 45 Gy was delivered in 3 fractions with cone beam computed tomography and 2-dimensional guidance.
Results:
The conventional 3-dimensional conformal plan, which fulfilled all dose constraints for target and organs at risk, was accepted for the treatment. Almost for all performed patient position verifications, on-line evaluated results were kept under 5 mm.
Conclusions:
The analysis presents the possible way of treating patients with liver metastasis. The SBRT treatment prepared and verified according our protocol can be implemented in clinical practice for a vast majority of such patients. The literature validation of our liver SBRT protocol showed that it has the potential for ensuring the effective and patient-friendly delivery.

p. 526
Shruthi Arora, Paul Christos, Anthony Pham, Prashant Desai, A Gabriella Wernicke, Dattatreyudu Nori, K. S. C. Chao, Bhupesh Parashar
DOI
:10.4103/0973-1482.138207
PMID
:25313732
Purpose:
Poorly differentiated thyroid carcinoma (PDTC) and anaplastic thyroid carcinoma (ATC) are considered the most aggressive cancers of the head and neck. The aim of the study was to evaluate and compare survival outcomes in PDTC and ATC in a large population-based cohort.
Materials and Methods:
Patients with PDTC and ATC diagnosed from 1973 to 2008 were obtained from Surveillance, Epidemiology, and End Results database. Kaplan-Meier survival analysis and log-rank analyses were performed to evaluate (1) The effect of histology on cause-specific survival (CSS) and (2) the influence of factors such as treatment, treatment sequence, race, sex, and age on CSS. Multivariate analysis was performed to assess the independent effect of these factors on CSS.
Results:
A total of 1352 patients with PDTC and ATC were identified. PDTC constituted 52.4% of patients versus 47.6% for ATC. Median CSS was similar in the two histology groups (
P
= 0.14). Both PDTC and ATC patients receiving radioisotopes showed a significantly better CSS compared to external beam radiation (
P
< 0.0001). PDTC and ATC Patients receiving radiation prior to surgery demonstrated a significantly lower CSS compared to patients receiving radiation postoperatively (
P
< 0.0001). Female gender and black/nonwhite race tended to improve CSS in PDTC and ATC patients (
P
= 0.29 and
P
= 0.03, for gender and race, respectively). However, multivariate analysis revealed only type of radiation treatment and age to be independently associated with CSS.
Conclusion:
This is the first large population-based study evaluating PDTC and ATC outcomes in patients who received radiation treatment. Radioisotope use and timing of radiotherapy (postoperative vs. preoperative) were associated with improved CSS in both histologies.

PMID
:25313733
Background:
Human papilloma viruses (HPV) have been detected in several types of cancers. Over the last few years, a possible correlation between HPV infection and colon cancers has been suggested. The aim of this study was to assess the presence of HPV-DNA in colon adenocarcinomas and adenomas to describe the relationship of HPV infection with these pathologic features.
Materials and Methods:
The study included formalin-fixed and paraffin-embedded tissue samples of 70 patients with colon adenocarcinoma and 30 patients with adenoma (as study group) and 30 tumor adjacent tissues (as control). HPV-DNA was purified and first amplified through MY09/MY11 and GP5+/GP6+ primers. Subsequently, for more precision, another PCR was performed using PGMY09/11 L1 consensus primer system.
Results:
All tested adenocarcinomas and adenomas as well as normal tumor adjacent tissues were negative for all types of HPV in two PCR assays.
Conclusion:
Our results do not support the relationship between HPV infection and colon carcinoma or adenoma. Attributing a role to the HPV in the etiology of colon carcinogenesis will require further studies.

p. 535
Suryanarayana S.V. Deo, Nootan Kumar Shukla, Paras Khanna, Deepak Jha, Archit Pandit, Sanjay Thulkar
DOI
:10.4103/0973-1482.139153
PMID
:25313734
Background:
Thirty to 40% of all extra thoracic cancers lead to secondary pulmonary lesions and approximately 20% of these cases feature metastases that are confined to the lungs. There is benefit of pulmonary metastasectomy in a select subset of patients.
Aims:
The goal of this study was to evaluate the patient profile, treatment patterns, and outcomes following surgical treatment of lung metastasis and to identify prognostic factors for long-term survival.
Materials and Methods:
Retrospective analysis of a prospectively maintained computerized database at a tertiary cancer care centre was done. 36 patients underwent curative resection for isolated pulmonary metastasis from January 1999 to December 2009. All metastasis were detected by non-contrast CT scan of the chest. Lung function tests were performed in all patients. Posterolateral thoracotomy was performed for resection of pulmonary metastasis by lung sparing procedures. A routine protocol of complete resection of all visible and palpable lung metastasis with a margin of 0.5 to 10 mm was followed in all patients. Staged thoracotomy was done for bilateral metastases. All palpable nodules were resected by wedge resection except in one case where pneumonectomy was done to achieve R0 resection. All patients underwent complete resection.
Conclusions:
Disease-free interval of more than 1 year along with less than 2 malignant nodules in patients with non-visceral pulmonary metastasis are variables identified in the present study which have enabled pulmonary metastasectomy to be offered as a safe therapeutic lifeline to patients.

p. 540
Kuntegowdanahalli C Lakshmaiah, SM Abhayakumar, Rachan Shetty, D Loknath, RS Jayashree, K Govindbabu
DOI
:10.4103/0973-1482.137908
PMID
:25313735
Background:
Febrile neutropenia is a medical emergency and it requires immediate hospitalization for evaluation and administration of empiric broad-spectrum antibiotics. The present study was undertaken to analyze the infectious agents, choice of empiric antibiotics, and outcome in high-risk febrile neutropenia in the solid organ malignancies.
Materials and Methods:
In this study, 92 high risk febrile neutropenic episodes were analyzed in 72 patients with solid organ malignancies. We used cefoperazone-sulbactum as an initial empiric antibiotic. Piperacillin/tazobactum or carbapenems were added to the patients who did not respond to initial antibiotic.
Results:
Among the 92 episodes treated, most patients received first-line chemotherapy for locally advanced disease. Microbes were isolated in 25% of febrile neutropenic episodes. Gram-negative organism (61.70%) constituted the most common isolates. The most common microbes identified were E. coli and Staphylococcus aureus in blood, Klebsiella pneumonia in sputum and E. coli in urine culture. Patients who had been treated with cefoperazone-sulbactum improved clinically in 70.6% of febrile neutropenic episodes. Second- line antibiotics (piperacillin-tazobactum with amikacin) were required in 24% episodes, while another 5.4% episodes required third-line antibiotics (carbapenems). In this study, mortality was seen in 12% of febrile neutropenic episodes. Staphylococcus aureus was 100% sensitive to linezolid, teicoplanin, and vancomycin, whereas Gram-negative organisms were 100% sensitive to imepenem and meropenem.
Conclusion:
Cephaperazone-sulbactum is a reasonable initial choice for empirical therapy in high risk febrile neutropenic patients in solid organ malignancies.

Identification of human prolactinoma related genes by DNA microarray
p. 544
Lin Zhao, Min Lin, Shousen Wang
DOI
:10.4103/0973-1482.137962
PMID
:25313736
Objective:
To identify the genes involved in prolactinoma by bioinformatics methods and provide new potential biomarkers for prolactinoma.
Materials and Methods:
The gene-expression profile data, GSE36314, including 4 prolactinoma samples and 3 controls, was downloaded from Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) were identified using the limma package in R and were then classified into different functional groups by COG (Clusters of Orthologous Groups) annotation based on BLASTX (Basic Local Alignment Search Tool). Transcriptional factors (TFs) were screened out by employing the Transcription Factor (TRANSFAC) database. An interaction network among DEGs and TFs was constructed by Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) software. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and Gene Ontology (GO) enrichment analysis were then performed for the genes in this network.
Results:
A total of 52 genes were identified as being significantly different between prolactinomas and normal samples which were classified into 29 COG functional categories. Three TFs, ZIC3 (Zic family member 3), NGFIC (nerve growth factor-induced protein C) and SP1 (Specificity Protein 1) were screened out, which can regulate part of DEGs. Two down-regulated genes, FSHB (follicle stimulating hormone β subunit) and LHB (luteinizing hormone β subunit) were involved in GnRH (gonadotropin-releasing hormone) signaling pathway.
Conclusion:
Several DEGs between prolactinoma and normal samples were identified in our study and candidate agents such as LHB and FSHB may provide the groundwork for a targeted therapy approach for prolactinomas.

DOI
:10.4103/0973-1482.137918
PMID
:25313737
Context:
Pilomatrixoma is a benign tumor of the skin. Malignant transformation can be seen rarely in the small percentage.
Aim:
The aim of the following study is to attract attention to this tumor in the differential diagnosis because if it is not kept in mind it leads to both unnecessary interventions and treatments for the patient. Patients and Methods: From January 2006 to December 2012, 8 patients with pilomatrixoma were evaluated retrospectively.
Results:
A total of 8 pediatric pilomatrixoma patients' charts were reviewed retrospectively. None of the patients had familial feature. Of 8 patients 4 (50%) were male and 4 (50%) were female. The patients' age ranged from 2-18 years with a median age 11.5 years. All of the patients were admitted with the complaint of swelling at the lesion site. Two patients have multiple lesions, one of them has two and other has three lesions. A total of 11 lesion were detected in our 8 patients that 5 of them were located upper extremities (46%), 3 of them cervical region (27%), 2 of them on occipital region (18%) and 1 of them in the sacral region (9%). All lesions were excised completely. Until now, no patient had evidence of recurrence or malignant disease.
Conclusion:
As a result pilomatrixoma is a benign tumor, with atypical forms and unfortunately, no tumor-specific diagnostic feature except of a careful histopathological examination is available.

Dynamic computed tomography and Doppler findings in different subtypes of renal cell carcinoma with their histopathological correlation
p. 552
Binit Sureka, Anupam Lal, N Khandelwal, Kusum Joshi, SK Singh, Mayank M Agarwal, Aliza Mittal
DOI
:10.4103/0973-1482.137924
PMID
:25313738
Background:
Renal cell carcinoma (RCC) is by far the most common soft-tissue mass and accounts for 85% of all malignant masses of the kidney. Histopathological subtype has clinical implications in the form of prognosis and response to various newer and adjuvant treatment strategies.
Aim:
The aim of this study was to evaluate the morphology and enhancement patterns of different subtypes of RCC and correlate them with their histopathological subtypes.
Materials and Methods:
The study group comprised of 20 consecutive patients of RCC. The patients were evaluated with multi-detector-row computed tomography (MDCT) and Doppler ultrasound prior to surgery and findings compared with histopathological subtypes of tumor.
Results:
RCC was confirmed on histopathology. Out of 20 patients with RCC, 14 were finally diagnosed as clear cell, 4 chromophobe and 2 as papillary subtypes of RCC. None of clear-cell type showed homogenous enhancement. The mean attenuation in corticomedullary phase (CMP) and nephrographic phase (NP) for clear cell and chromophobe subtype was higher than papillary subtype, i.e. 116.1 ± 27 HU and 91.9 ± 21 HU for clear cell, 103 ± 22.4 HU and 96.2 ± 9.2 HU for chromophobe subtype and 78.5 ± 12.4 HU and 73.3 ± 12.2 HU for papillary subtype respectively. On Doppler US evaluation, non-clear-cell subtypes, which showed heterogenous enhancement on MDCT showed less color flow and peak systolic velocity (PSV). The difference in PSV and Doppler shift frequency values between clear-cell carcinoma and chromophobe subtypes were statistically significant (
P
= 0.003).

DOI
:10.4103/0973-1482.137943
PMID
:25313739
Aims:
The aim of this study was to evaluate and compare the effect of radiotherapy on testicles with different treatment positions and plans for rectal cancer patients.
Settings and Design:
Mono-institutional prospective study. Patients and Methods: Three different plans; supine 4-fields (s4f), prone 4-fields (p4f), and prone 3-fields (p3f) of 15 male patients with rectal carcinoma receiving 45 Gy pelvic radiotherapy were evaluated. Testicular doses in each plan were calculated. Since the localizations of the primary tumor may affect testicular dose, boost doses were not taken into account.
Statistical Analysis Used:
Kruskal Wallis test, Pearson and Spearman correlation analysis.
Results:
Median cumulative testicular doses of s4f, p4f, and p3f plans were 19.8, 69.3, and 100.8 cGy, respectively (
P
= 0.013). Median V0.5 (Volume receiving more than 0.5 Gy) and V1 (Volume receiving more than 1 Gy) for testicles were also significantly lower in s4f plans (3%, 60.7%, and 78.1% for V0.5 and 0.3%, 35.8%, and 52.3% for V1 in s4f, p4f, and p3f, respectively) (
P
= 0.001). The median distances between lower edge of fields and testicles in s4f, p4f, and p3f plans were 65 mm, 29 mm, and 29 mm, respectively (
P
< 0.01). Median bladder doses were significantly lower in p3f plans (
P
= 0.002).
Conclusions:
S4f external beam radiotherapy for rectal carcinoma allows better testicular dose than p3f and p4f. The probably reason was the increase of distance between lower edge of the field and testicles.

Context:
The diagnosis of malignant and potentially malignant epithelial lesions of oral mucosa cannot be based solely on clinical findings. The histologic evaluation of a representative biopsy specimen thus becomes necessary. The site for biopsy, however, is always a subjective choice that sometimes raises doubts about its representativeness. So far, no simple and reliable method is available for the selection of the most appropriate area for biopsy. Colposcopy is helpful in the selection of these sites of epithelial dysplasia depending upon the vascular patterns.
Aims:
The study was planned to assess the role of colposcopic examination in the selection of biopsy site in patients with varying grades of oral epithelial dysplasia at various sites.
Settings and Design:
Fifty patients between the ages of 30-60 years clinically diagnosed with leukoplakia and carcinoma buccal mucosa were included in the study.
Materials and Methods:
For each of the subject, a thorough clinical examination followed by colposcopic assessment was carried out for the selection of biopsy site from the involved mucosa. The histopathological findings were then compared in the two cases and results analyzed.
Statistical Analysis Used:
The statistical analysis was done using paired t-test.
Results:
In our study, sensitivity and specificity for the selection of biopsy site by colposcopic examination came out to be higher for leukoplakia than carcinoma buccal mucosa patients.
Conclusions:
It was concluded that colposcopic examination was found more significant in the selection of biopsy site for leukoplakia patients while clinical criterion was found to be more appropriate for carcinoma buccal mucosa cases.

Introduction:
Urachal carcinoma is a rare malignancy of urogenital tract. The objective of this study was to assess the clinical presentation, histopathological findings, treatment and outcome of patients of urachal carcinoma at a tertiary care centre.
Materials and Methods:
A retrospective analysis of six cases of urachal carcinoma diagnosed over a period of 7 years from 2005 to 2011 was carried out. All pathologic specimens were reviewed by a single pathologist. Clinical and histological features along with treatment were reviewed and patient follow-up and survival outcome was obtained.
Results:
The mean age at diagnosis was 36 years. Of the six patients, five were male. The tumor was located in dome in five and dome and anterior wall in one patient. All patients underwent partial cystectomy with bilateral pelvic lymph node dissection. The Sheldon pathologic stage was stage II in 1, IIIA in 2, IVA in 3 cases. Five out of six patients received adjuvant radiotherapy. The mean follow-up period was 37 months. Three out of six were disease free at last follow-up.
Conclusions:
Urachal carcinomas are rare and usually locally advanced at presentation with a high risk of distant metastases. Surgery is the primary treatment of choice. Adjuvant therapy may decrease the chances of recurrence but it needs to be elucidated by prospective trials.

Objective:
The objective of this study was to investigate the potential role of RapidArc (RA) compared with helical tomotherapy (HT), sliding window intensity modulated radiotherapy (SW IMRT) and three-dimensional conformal radiation therapy (3D CRT) for localized prostate cancer.
Materials and Methods:
Prescription doses ranged from 60 Gy to planning target volume (PTV) and 66.25 Gy for clinical target volume prostate (CTV-P) over 25-30 fractions. PTV and CTV-P coverage were evaluated by conformity index (CI) and homogeneity index (HI). Organ sparing comparison was done with mean doses to rectum and bladder.
Results:
CI
95
were 1.0 ± 0.01 (RA), 0.99 ± 0.01 (HT), 0.97 ± 0.02 (IMRT), 0.98 ± 0.02 (3D CRT) for PTV and 1.0 ± 0.00 (RA, HT, SW IMRT and 3D CRT) for CTV-P. HI was 0.11 ± 0.03 (RA), 0.16 ± 0.08 (HT), 0.12 ± 0.03 (IMRT), 0.06 ± 0.01 (3D CRT) for PTV and 0.03 ± 0.00 (RA), 0.05 ± 0.01 (HT), 0.03 ± 0.01 (SW IMRT and 3D CRT) for CTV-P. Mean dose to bladder were 23.68 ± 13.23 Gy (RA), 24.55 ± 12.51 Gy (HT), 19.82 ± 11.61 Gy (IMRT) and 23.56 ± 12.81 Gy (3D CRT), whereas mean dose to rectum was 36.85 ± 12.92 Gy (RA), 33.18 ± 11.12 Gy (HT, IMRT) and 38.67 ± 12.84 Gy (3D CRT).
Conclusion:
All studied intensity-modulated techniques yield treatment plans of significantly improved quality when compared with 3D CRT, with HT providing best organs at risk sparing and RA being the most efficient treatment option, reducing treatment time to 1.45-3.7 min and monitor unit to <400 for a 2 Gy fraction.

A study on the necessity of kV-CBCT imaging compared to kV-Orthogonal portal imaging based on setup errors: Considering other socioeconomical factors
p. 583
Om Prakash Gurjar, Surendra Prasad Mishra, Virendra Bhandari, Pankaj Pathak, Sidharth Pant, Prapti Patel
DOI

PMID
:25313743
Purpose:
Evaluation of setup accuracy in kV-orthogonal portal imaging (OPI)-based and kV-CBCT-based radiotherapy treatment and to find out the necessity of cone-beam computed tomography (CBCT) compared to OPI.
Materials and Methods:
A retrospective study was carried out on 30 patients, who received radiotherapy to the Brain, Head and Neck, and Pelvis. In the OPI technique, anterior-posterior and right-lateral portal images were taken by the On Board Imaging (OBI) system and were superimposed on the reference images. Similarly, in the kV-CBCT technique, CBCT was performed by the OBI system and CBCT images were superimposed on the reference CT images. A total of 150 comparison sets of kV-OPI and kV-CBCT images were analyzed and evaluated. Shifts in the Lateral, Longitudinal, and Vertical directions were noted in both techniques. The iso displacement vector (IDV) was calculated for all imaging.
Results:
The mean IDV (in cm) are found to be 0.3395 (SD: 0.1477) and 0.3088 (SD: 0.1593) in cases of the brain, 0.4266 (SD: 0.1511) and 0.3666 (SD: 0.1533) in cases of the head and neck, and 1.0339 (SD: 0.5893) and 0.9498 (SD: 0.6047) in cases of the pelvis for the CBCT and OPI techniques, respectively. The P values were 0.3201, 0.0515, and 0.4829 for the brain, head and neck, and pelvic cases, respectively.
Conclusions:
There is statistically no significant difference between both the imaging techniques. As the dose delivered by the CBCT technique is higher than that by the OPI technique, from the socioeconomical and radiation safety point of view, the OPI technique is possibly better than the CBCT technique. Hence, it can be concluded that CBCT is not a mandatory technique compared to the OPI technique in routine brain, head and neck, and pelvic cases, except in those cases where better information about interfraction movements of soft tissue is necessarily required for positioning of the target, as is the case in prostate carcinoma.

Granzyme B gene polymorphisms, colorectal cancer risk, and metastasis
p. 587
Nizar M Mhaidat, Sayer I Al-azzam, Karem H Alzoubi, Omar F Khabour, Baraa F Gharaibeh
DOI
:10.4103/0973-1482.137940
PMID
:25313744
Context:
The human granzyme B protein (GrB), which is encoded by granzyme B gene (GZMB), plays a major role in eliminating cancer cells. Polymorphisms of GZMB gene such as Q55R, P94A, and Y247H have been shown to affect GrB activity and the subsequent cancer risk.
Aims:
In this study, we examined possible association between GZMB gene polymorphisms and susceptibility to colorectal cancer (CRC). In addition, the contribution of the examined polymorphisms to colorectal cancer metastasis to lymph node and distant organ was investigated.
Materials and Methods:
A total of 50 venous blood samples collected from CRC patients were analyzed to identify the Q55R, P94A, and Y247H polymorphisms. As a control group, 20 healthy subjects were enrolled in the study. The Q55R, P94A, and Y247H polymorphisms were genotyped by polymerase chain reaction and sequencing method. Statistical Analysis: Data analysis was carried out using the statistical package SPSS version 17 to compute all descriptive statistics. Chi-square and Fisher exact tests (if the expected value in any cell is less than 5) were used to evaluate the genotype distribution and allele frequencies of the studied polymorphism.
Results:
The results revealed that the distribution of Q55R, P94A, and Y247H are not significantly different in CRC patients compared to the controls. In addition, no association between Q55R, P94A, and Y247H polymorphisms and its metastasis to lymph node and distant organ was detected.
Conclusions:
These results suggest that GZMB Q55R, P94A, and Y247H polymorphisms are not significantly associated with colon cancer incidence, or metastasis to lymph node and distant organ. However, this study was limited by its relatively small sample size; thus, to confirm current findings, a bigger multicenter design study is warranted.

Effect of β-catenin alterations in the prognosis of patients with sporadic colorectal cancer
p. 591
Sara Rafael, Silvia Veganzones, Marta Vidaurreta, Virginia de la Orden, Maria Luisa Maestro
DOI
:10.4103/0973-1482.139161
PMID
:25313745
Context:
Wnt pathway activation represents a critical step in the etiology of most of colorectal cancer (CRC) and it is commonly due to mutations in the APC gene, which originates the loss of β-catenin regulatory function. It has been suggested that APC inactivation or β-catenin alteration have similar effects in tumor progression in CRC tumorigenesis.
Aims:
The aim of this study was to analyze the frequency of β-catenin gene mutation in patients with sporadic CRC and to determine its effect in prognosis.
Materials and Methods:
This was a prospective cohort study, which included 345 patients with sporadic CRC. β-Catenin gene mutations in exon 3 were detected by single strand conformation polymorphism (SSCP). Exon 3 deletion was studied by identifying differences in fragment length of specific amplification products. All the altered samples were confirmed by direct sequencing.
Results:
In our population, point mutations were detected in 1.8% of the samples and 4.9% of the samples showed deletion. We observed association between exon 3 mutations and increased levels of Carcinoenbryonic Antigen (CEA). In these patients, clinically relevant improvement in overall survival was also observed.
Conclusion:
Frequency of point mutations in exon 3 β-catenin gene is low in our population. It would be interesting to increase the population size to test the clinically relevant influence in the prognosis found, and to test the relation of these events with Microsatellite Instabillity (MSI) pathway. If these findings were confirmed, β-catenin determination would help in the selection of patients with different prognosis.

PMID
:25313746
Objective:
Patients with small-cell lung cancer (SCLC) are at high risk of developing brain metastases (BM). Fractionated stereotactic radiotherapy (FSRT) alone or combined with whole brain radiation therapy can be used to treat intracranial metastases. This study was aimed to explore FSRT for BM from SCLC.
Materials and Methods:
We retrospectively analyzed 45 patients with BM from SCLC treated with fractionated linear accelerator FSRT. Multivariate analysis was used to determine independent risk factors of overall survival (OS).
Results:
There were 35 patients treated with salvage FSRT and 10 patients treated with primary FSRT. The median OS was 10 months from the beginning of FSRT and 19 months from diagnosis of BM. The median OS of salvage FSRT group and primary FSRT group was 22 and 10 months from the diagnosis of BM, respectively (
P
= 0.011); 11 and 8 months from FSRT, respectively (
P
= 0.828). Recursive partitioning analysis class and the stage of the primary tumor were independent predictors of increased OS (relative risk [RR] = 2.634,
P
= 0.021 and RR = 2.324,
P
= 0.0210, respectively).
Conclusions:
Salvage and primary FSRT were both effective treatment options for BM from SCLC. Salvage and primary FSRT may have different OS from the time of diagnosis of BM.

Effect of sarcosine on endothelial function relevant to angiogenesis
p. 603
Peruman R Sudhakaran, Sheela Binu, Sasikumar J Soumya
DOI
:10.4103/0973-1482.137945
PMID
:25313747
Aim of Study:
Endothelial cells (ECs) respond to changes in metabolic status and switch over to angiogenic phenotype. There are several metabolites known to mediate this transition; however, the effect of sarcosine that accumulates in invasive prostate cancer is not known. The objective of the study was to examine whether sarcosine influences EC function and affects angiogenesis.
Materials and Methods:
The effect of sarcosine was studied using different model systems including chick chorioallantoic membrane (CAM), rat aortic rings in culture, and human umbilical vein ECs (HUVECs) in culture. The statistical significance of difference was analyzed by one-way analysis of variance (ANOVA) and Student's t-test using GraphPad 5 software.
Results:
Increased vascularization in CAM, increased endothelial sprouting in rat aortic rings in culture, and increased expression of CD31 and E-selectin suggested a possible angiogenic effect of sarcosine. Sarcosine modulated expression of angiogenic growth factors such as vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF). In ECs in culture LY294002, an inhibitor of phosphatidylinositol-3-kinase (PI3K)/Akt pathway and rapamycin, an inhibitor of mammalian target of rapamycin (mTOR) reversed the effect of sarcosine. Further, sarcosine induced upregulation and activation of Akt in HUVECs.
Conclusion:
These results suggest that sarcosine modulates EC function relevant to angiogenesis through modulation of PI3K/Akt/mTOR pathway.

DOI
:10.4103/0973-1482.137941
PMID
:25313748
Aim of the Study:
Statistical analysis of pre-treatment dose verification of intensity-modulated radiotherapy (IMRT) fields to assess the quality of the IMRT practice at different radiotherapy centers.
Materials and Methods:
The dose verification data acquired by the institutional physicist of 10 different hospitals for various types of patients were collected and analyzed for mean, median, standard deviation (SD), range, minimum and maximum % deviation. The percentage of cases having positive and negative dose differences as well dose differences within ± 3% were also determined.
Results:
The mean values of percentage variation in difference between treatment planning systems calculated dose and difference between measured dose (D
TPS
and D
Meas
) are found to be from – 1.79 to 1.48 and median from – 1.79 to 1.51. The SDs are found to be from 0.76 to 3.70. The range of variation at these centers varies from 3.99 to 16.45 while minimum and maximum values of percentage variation in difference between D
TPS
and D
Meas
ranges from – 10.33 to 13.38. The percentage of cases having positive dose difference ranges from 8 to 94 and cases having negative dose difference ranges from 6 to 92. The percentage of cases having dose difference within ± 3% varies from 57 to 100.
Conclusion:
IMRT centers are having random and biased (skewed towards over or under dose) distribution of the percentage variation in difference between measured and planned doses. The analysis of results of the IMRT pre-treatment dose verification reveals that there are systematic errors in the chain of IMRT treatment process at a few centers. The dosimetry quality audit prior to commissioning of IMRT may play an important role in avoiding such discrepancies.

PMID
:25313749
Objectives:
To investigate the approach of both pharmacies and herbalists' shops while offering a proper advice for patients seeking guidance on a potentially malignant oral lesion.
Materials and Methods:
A cross-sectional, descriptive study was undertaken using the standardized patient approach on a representative sample of pharmacies and herbalists' shops in Bhopal city. The study sample was selected by stratified random sampling technique and was contacted by telephone. Our patient's introductory statement was, "I have a painful ulceration on the tongue since 3 months. What would you advise?" To avoid the hypothetical bias in telephone answers, another study was designed for two regions of the city, of which pharmacies were visited in one and herbal shops in the other one.
Results:
A total of 497 establishments were contacted. Out of these, 368 were pharmacies (74.1%) and 129 were herbalists' shops (25.9%). Patients with potentially malignant lesions were more frequently referred to a dentist (16.03%) or a physician (23.36%) by the pharmacies compared to the herbalists' shops. In contrast, most of the herbalists' shops prescribed over-the counter (OTC) remedies (66.66%) and showed no interest in referring the patient to a dentist or a physician.
Conclusion:
Apart from pharmacists, the new probable off-clinical counselors (herbalists and pharmacy assistants) have been identified as potential factors of patient diagnostic delay in oral cancer. Educational strategies to improve advice and referral for these identified groups should be designed.

Context:
The pepino fruit
Solanum muricatum
Ait. (Solanaceae) is commonly known as melon pear and sweet cucumber grown in South America, New Zealand, and India. Traditionally, the fruits are used in the treatment of diabetes and cancer.
Aim:
The objective of present study is to explore the immunomodulatory, anticancer, and anti-inflammatory activities of the methanol extract of
S. muricatum
fruits in experimental mice models.
Materials and Methods:
Immunomodulatory activity of
S. muricatum
fruits was evaluated by assessing the relative organ weight, bone marrow cellularity, α-esterase activity, and by studying the phagocytic activity by carbon clearance test. The anti-tumor activity of the fruit extract was studied against Dalton's lymphoma ascites (DLA) cell line induced solid and ascites tumor models. The anti-inflammatory activity of the fruit extract was evaluated using carrageenan and formaldehyde models.
Statistical Analysis:
The results were expressed as mean (±SD). Statistical analyses were performed using a one-way analysis of variance (ANOVA) followed by Dunnett's test using GraphPad Instat software.
P
values less than 0.05 were considered statistically significant.
Results:
S. muricatum
treatment could not only stimulate the immune system but also significantly (
P
< 0.01) inhibit the growth of transplantable tumor. The serum glutathione and γ-glutamyl transpeptidase (GGT) levels were found to be significantly decreased compared with tumor-bearing control animals. The increased tumor necrosis factor (TNF)-α level in tumor control (802.6 ± 12.0) was significantly (
P
< 0.01) decreased to 175.2 ± 16.5 after
S. muricatum
treatment. The TNF-α level in normal animals was found to be 21.0 ± 3.5 pg/ml. An increase in life span was observed after
S. muricatum
treatment. The extract also inhibited the edema induced by carrageenan and formaldehyde, respectively.
Conclusion:
The results showed that the
S. muricatum
fruit extract has potent immunomodulatory, anticancer, and anti-inflammatory activities.

DOI
:10.4103/0973-1482.139159
PMID
:25313751
Context:
There is a rising trend in the incidence of (colorectal carcinoma) colorectal cancer (CRC) in India. Nuclear factor kappa B (NFkB) is a transcription factor which belongs to the Rel family. It has an impact on phenomena such as apoptosis, tumor progression and differentiation.
Aims:
(1) To evaluate the grade and stage in 50 cases of colorectal carcinoma. (2) To evaluate the NFkB translocation into the nucleus of the cells. (3) To compare the benign and malignant areas with the degree of NFkB translocation and compare the translocation with the grade and pathological stage.
Subjects and Methods:
The grade and stage of the tumors was evaluated. NFkB staining was performed on the tissues. The results of the immunostaining were analyzed semi quantitatively as a percentage of positive cells.
Statistical Analysis Used:
Statistical Package for Social Sciences 13.0 statistical package program (SPSS, Lead Technologies Inc, USA) for windows was used. Correlation was carried out using the Pearson's correlation co-efficient and the Chi-square test.
Results:
There were 29 males (58%) and 21 females (42%). Most of the cases were well-differentiated adenocarcinomas (58%). There was a significant difference between NFkB translocation in the epithelial cells and lymphocytes in the benign and malignant areas (
P
- 0.04 and
P
- 0.001 respectively). There was a significant correlation between the grade of NFkB staining in the malignant epithelial cells with the tumor and nodal status (
P
- 0.001 and
P
- 0.001).
Conclusions:
It is likely that NFkB is an important factor in the pathogenesis of CRC. Further studies including therapeutic intervention using strategies which prevent activation of NFkB in colorectal carcinoma patients will tell if we could alter the course of the disease favorably.

The analysis of deregulated expression and methylation of the
PER
2 genes in gliomas
p. 636

DOI
:10.4103/0973-1482.138202
PMID
:25313752
Context:
Growing evidence shows that disruption of circadian rhythm may be a risk factor in the development of glioma. However, the molecular mechanisms of genes controlling circadian rhythm in glioma cells have not been explored and differential expression of the circadian clock genes in glioma and non-tumor cells may provide a molecular basis for manifesting this mechanism.
Aims:
The aim of the following study is to analyze the
PER2
expression involved in the pathogenesis of glioma.
Materials and Methods:
Using immunohistochemical staining, methylation specific polymerase chain reaction techniques, we examined the expression of the most important clock genes,
PER2
, in 92 gliomas.
Statistical Analysis Used:
The association between tumor grade (high-grade/low-grade gliomas) and expression of the investigated proteins (negative/positive) was assessed using the Spearman, Chi-square test and two-sample
t
-test, included in the Statistical Package for the Social Science, version 13.0. Using Spearman Correlation to analyse correlation between the expression of PER 2 and
PER2
promoter methylation.
Results:
Our results reveal disturbances in the expression of the period 2 (
PER2
) genes in most (52.17%) of the glimoa cells in comparison with the nearby non-cancerous cells and the
PER2
gene deregulation is most probably by methylation of the
PER2
promoter.
Conclusions:
Since, the circadian clock controls expression of cell-cycle related genes, we suggest that disturbances in
PER2
gene expression may result in disruption of the control of the normal circadian clock, thus benefiting the survival of cancer cells and promoting carcinogenesis. Differential expression of circadian genes in non-cancerous and cancerous cells may provide a molecular basis for chronotherapy of glioma.

DOI
:10.4103/0973-1482.139154
PMID
:25313753
Aim
of
the
Study:
Ki-67 labeling index (LI) is used in the assessment of cell proliferating activity. It has been widely documented for various human tumors, including the brain neoplasms. The aim of the present study is to evaluate Ki-67 as proliferative index in the grading of astrocytomas in order to predict the biological behavior of the tumor and prognosis of patients.
Materials and Methods:
In the present study, a total of 105 patients with astrocytomas were included. Ki-67 LI was done on all the astrocytomas and was compared in correlation with World Health Organization histological grading of astrocytomas.
Results:
The mean Ki-67 LI in Grade I astrocytomas was 3.36 ± 4.59 standard deviation (SD), 7.05 ± 4.16 SD in Grade II astrocytomas, 28.24 ± 6.23 SD in Grade III astrocytomas and 38.7 ± 7.19 SD in Grade IV astrocytomas. P values were significant between all grades of astrocytomas except between Grade I and Grade II tumors which was 0.5076.
Conclusions:
Assessment of astrocytic tumor proliferative potential provides important prognostic information that supplements standard histological grading. Ki-67 LI is the simplest and most reliable methods of all. This study demonstrates that, Ki-67 LI serves as an important prognostic marker in human astrocytomas. Ki-67 LI solely correlates with a grade of the tumor. Average level of Ki-67 LI varies between different grades of astrocytic tumors but some overlap of values does exist.

p. 651
Xin Zhao, Rui Wang, Yu Qian, Guijie Li, Yalin Zhou, Peng Sun
DOI
:10.4103/0973-1482.138081
PMID
:25313755
Background:
Insect tea is a particular drink or health product in China and it is also used as Chinese medicine now. Its functional effects need to be proved.
Materials and Methods:
The ICR mice buccal mucosa cancer model was established by injecting the mice with U14 cells and mice was treated with insect tea. Tumor volumes and lymph node metastasis rates were determined. And the buccal mucosa tissues and cancer cervical lymph node were also checked by histology test, real-time polymerase chain reaction, and western blot assays.
Results:
The tumor volumes for the group treated with insect tea mice was smaller than those from the control mice. The sections of buccal mucosa cancer tissue showed that the canceration of insect tea mice was weaker than control mice. Insect tea significantly induced apoptosis in buccal mucosa tissues by upregulating Bax, caspases, and downregulating Bcl-2. Nuclear factor-κB, inducible nitric oxide synthase, and COX-2 gene, was significantly downregulated by insect tea, demonstrating its anti-inflammatory properties. Insect tea also exerted a great anti-metastasis effect on tissues as demonstrated by decreased expression of Matrix metalloproteinases genes and increased expression of tissue inhibitors of matrix metalloproteinases.
Conclusion:
The highest concentration of 1600 mg/kg oral gavage and 400 mg/mL smear insect tea showed the best anticancer effects. Based on the results, insect tea showed the strong in vivo buccal mucosa cancer preventive effects.

DOI
:10.4103/0973-1482.137985
PMID
:25313756
Objective:
To determine the effect of moderate-intensity aerobic exercise on the quality of life (QOL) and physical functioning in breast cancer survivors.
Materials and Methods:
We randomly assigned 62 breast cancer survivors to an exercise (
N
= 30) or control group (
N
= 32). The exercise group trained at a moderate intensity progressing from 25 to 40 min over a 10-week period. The control group did not train. Outcomes were assessed at baseline and postintervention. The primary outcomes were overall QOL - as assessed by the functional assessment of cancer therapy-breast (FACT-B) scale. Secondary outcomes were changes in various subscales of overall QOL, and changes in body composition outcomes: body weight, body mass index, and changes in performance in a 12 min walk test (12MWT).
Results:
Sixty-two of 73 women randomized (84.9%) completed the study. There were no significant differences amongst the two groups at baseline for any variable. In the exercise group significant improvements were demonstrated for the FACT-B (13.4 points,
P
< 0.003), functional assessment of cancer therapy-general (FACT-G) (9.16 points,
P
< 0.008), the functional well-being subscale (
P
< 0.010), and the emotional well-being subscale (
P
< 0.035) compared to the control group. No significant changes in body weight or BMI were observed. Exercise group showed a significant increase in 12MWT (
P
< 0.009).
Conclusion:
We conclude that 10 week of moderate-intensity aerobic exercise program significantly improves QOL and physical functioning in breast cancer survivors. Future studies are needed to evaluate the effectiveness of similar exercise programs over longer periods of time and involving a greater number of breast cancer survivors.

Introduction:
The p53 gene therapy showed promising results for treatment of numerous cancers particularly in combination with chemotherapy or radiotherapy. Gene therapy combining two or more treatment options may lead to the synergistic effects between diverse therapies and provide many opportunities in our fight against cancer. Aim: This study focused on the effects of p53 combining with the suicide gene therapy, nitroreductase (NTR)/5-(aziridin-1-yl)-2,4 dinitrobenzamide, on different cancer cell lines.
Materials and Methods:
Effects of adenoviral expressing p53 alone or in combination with wild type (WT) NTR, NTR single mutant, F124N and two NTR double mutants, T41L/N71S and T41L/F70A on survival rate of A549, QU-DB, MCF-7, MDA-MB-468 and DU145 cancer cell lines were determined by MTT assay. Expressions of MDM2 and TP53 transcripts were then assessed by quantitative real-time polymerase chain reaction in p53, NTR and combination of p53 with NTR infected cell lines.
Results:
According to the results, combination of p53 with NTR double mutant, T41L/F70A or NTR single mutant F124N, showed statistically significant decrease in vitality of all cancer cell lines studied compared with status of IC
50
from p53 or WT NTR and other NTR mutants alone (P < 0.05). Expressions of TP53 and MDM2 were downregulated in all T41L/F70A infected cells except for MCF-7.
Conclusion:
Combination of T41L/F70A NTR with p53 may have more advantages for treatment of different types of cancers compared to the other NTRs and p53 alone. The present study results may open new windows for getting desired outcome in gene therapy of different types of cancer.

Cyclin D1 expression in ductal carcinoma of the breast and its correlation with other prognostic parameters
p. 671
Gayatri Ravikumar, Anuradha Ananthamurthy
DOI
:10.4103/0973-1482.138135
PMID
:25313758
Purpose:
Cyclin D1 is a cell cycle regulatory gene emerging as a potentially significant oncogene in invasive breast cancers. In this study, we attempted to see the expression of Cyclin D1 in invasive ductal carcinomas of the breast in our population and correlate its expression with other known prognostic parameters.
Materials and Methods:
A total of 39 cases were selected from our case files from January 2011. Immunohistochemistry for Cyclin D1 was performed and interpreted as positive when >10% of the tumor cells expressed the marker with a moderate to strong intensity of staining. Clinicopathological parameters such as laterality, focality, tumor size, grade, ductal carcinoma in situ (DCIS), axillary lymph node (ALN) metastasis, hormone receptor status and human epidermal growth factor receptor 2 status were analyzed and correlated with Cyclin D1 expression.
Results:
The patients' age ranged from 30 to 76 years (mean = 53.18). The tumors were unilateral and unifocal in 38 cases; one patient had bilateral synchronous tumors. The majority were grade2 (67.5%) and tumor size T2 (57.5%). Nearly 35% were associated with DCIS and 57.5% had ALN metastasis. Estrogen receptors (ER) and progesterone receptor (PgR) positivity was seen in 65% of the cases and 25% was triple negative. Cyclin D1 expression was seen in 67.5% of the cases in our study. Among the ER, PgR positive and Her-2 negative tumors, Cyclin D1 expression was seen in the majority of cases (92%) cases, whereas none of the triple negative tumors showed Cyclin D1 expression. The other prognostic parameters such as tumor size, grade and lymph node status did not show any association with Cyclin D 1 positivity.
Conclusions:
Cyclin D1 expression was seen in 67.5% of ductal carcinoma and it showed a significant correlation with ER, PgR expression (92% in this study), which is in concordance with other similar studies in literature.

Spiritual well-being and its influence on fatigue in patients undergoing active cancer directed treatment: A correlational study
p. 676
Shirley Lewis, Naveen Salins, M Raghavendra Rao, Amrit Kadam
DOI
:10.4103/0973-1482.138125
PMID
:25313759
Introduction:
Spiritual well-being and fatigue are key parameters in assessing health related quality of life that determine treatment tolerance, treatment outcomes and reflect patient's coping ability in the illness-wellness disease trajectory.
Materials and Methods:
A total of 200 patients on active cancer treatment were enrolled to the study. Functional assessment of chronic illness therapy-spirituality (FACIT-Sp) and FACIT-Fatigue scales were used to assess spiritual well-being and fatigue scores during their cancer treatment. Data were analyzed using one-way analysis of variance and bivariate relationships determined using the Spearman Correlation analysis. Linear regression analysis was performed to determine predictors of fatigue score during treatment.
Results:
Mean spiritual well-being score was 20.96 out of 48 and scores were significantly higher in females compared with males (
P
= 0.03), lower with higher stage (
P
= 0.008) and lower in head and neck and gastrointestinal malignancies (
P
= 0.03) when compared with gynecological and breast malignancies. Fatigue was present in all the 200 patients studied and the mean fatigue score was 13.09. Higher fatigue scores were observed in patients with advanced stages of cancer (Stage IV) (F [3,199] = 5.67,
P
= 0.001). There was a significant inverse relationship between fatigue scores with spiritual well-being (
P
< 0.001). Spiritual well-being score emerged as a significant primary negative predictor (β = -0.23,
P
= 0.001) for fatigue scores followed by stage of disease (β =0.23,
P
= 0.001) and gender (β = -0.18,
P
= 0.01) as significant secondary predictors.
Conclusion:
Fatigue during cancer directed treatment is influenced by spiritual wellbeing, disease stage and gender. Further studies should examine the mediating variables that influence fatigue.

Aim:
The aim of this study was to determine the expression levels of serum ferritin (SF) and investigate the correlation between SF expression levels and clinical characteristics as well as the efficacy to platinum-based chemotherapy for advanced non-small cell lung cancer (NSCLC) patients.
Materials and Methods:
Electrochemiluminescence method was used to determine the expression levels of SF in the peripheral blood of 46 advanced NSCLC patients and 63 healthy subjects.
Results:
The expression levels of SF in healthy subjects were significantly lower than those in patients with advanced NSCLC patients (t = −3.279,P = 0.001). There was a statistically significant difference between SF expression levels and distant metastasis, regional lymph node metastasis, respectively (P < 0.05). However, there was no correlation between SF expression levels and sex, age, eastern cooperative oncology group performance status, smoking history, pathological type, tumor location and tumor-node-metastasis stage (All P > 0.05). The overall response rate to platinum-based chemotherapy was 57.1% (12/21) in normal SF expression levels group, which was significantly higher than that was 28% (7/25) in high SF expression levels group (χ
2
= 3.998,P = 0.046).
Conclusions:
SF may be a valuable blood marker for predicting the tumor progression and the efficacy of platinum-based therapies for advanced NSCLC patients.

PMID
:25313761
Aim of the Study:
The objective is to assess the utility of the p63 and α-methylacyl CoA racemase (AMACR) in resolving suspicious foci in prostatic needle biopsy and transurethral resection of prostate (TURP) specimens.
Materials and Methods:
A total of 470 cases are selected. These included 310 TURP specimens, 157 needle biopsies and 03 radical prostatectomy specimens. All the cases are reviewed and divided into three categories. Benign (370), cases with suspicious foci (40 cases) and malignant (60 cases). Immunohistochemistry (IHC) was carried out using monoclonal AMACR and p63 antibodies in the 40 suspicious cases along with positive and negative controls.
Results:
This study showed AMACR had a sensitivity of 95%, specificity of 92.5%, whereas p63 had a sensitivity of 90%, specificity of 100%. All the 40 suspicious cases were resolved using a combination of morphology and IHC expression p63 and AMACR. In 13 (32.5%), of the 40 suspicious cases there was change of diagnosis based of morphology, clinical details and staining with p63 and AMACR, In the 11 cases (11/40), diagnosis was changed from the benign to malignant. In one case benign to high grade prostatic intraepithelial neoplasia (1/40) and in one case from malignant to benign (1/40). This change was statistically significant with
P
value of 0.013.
Conclusions:
Combination of p63 and AMACR is of great additional value in combating the morphologically suspicious cases and should be used on case to case basis especially in prostatic needle biopsies and small foci lesions.

DOI
:10.4103/0973-1482.138122
PMID
:25313763
Objective:
Melanoma is an aggressive tumor with propensity for early metastasis and poor prognosis with delayed diagnosis. Matrix metalloproteinase-2 (MMP-2) is involved in degradation of extra-cellular matrix proteins and tumor progression. Ki-67 is a predictor of tumor proliferation activity but its prognostic significance in melanoma is controversial. In this study, the prognostic value of MMP-2 and Ki-67 via immuno-staining in head and neck melanoma is investigated.
Material and Methods:
A retrospective analysis of 24 consecutive primary melanoma samples was performed. All samples were stained with monoclonal MMP-2 and Ki-67 antibodies. Two independent investigators evaluated the stained sections. The reactive cells were considered positive regardless of the staining intensity and reported as percentage.
Results:
A strong correlation between MMP-2 expression, Breslow tumor thickness, and Clark level of invasion was observed (
r
= 0.85,
P
< 0.0001 and
r
= 0.84,
P
< 0.0001, respectively). A significant positive correlation was observed between MMP-2 expression and number of lymph node involved (
r
= 0.55,
P
value 0.005). MMP-2 over expression (>50%) was an independent predictor of lymph node involvement (OR: 2.1,
P
value: 0.01). No significant association was observed between Ki-67 expression and Breslow tumor thickness, Clark level, or lymph node involvement.
Conclusion:
MMP-2 expression correlates with tumor thickness in melanoma and is an independent predictive factor for lymph node involvement.

PMID
:25313764
Background:
Both chronic and acute inflammatory circuits are known to be associated with malignancy and drug resistance indicating that many antiinflammatory agents can potentially act as chemotherapeutic drugs. A series of new class of propanediones with good antiinflammatory activity were shown to possess moderate cytotoxic activities.
Aim:
The aim of the study was to evaluate this new series of 1-(2′,4′-difluorophenyl)-3-(substituted phenyl)-1,3 propanediones (PR 1-7) for their caspase dependent apoptotic activity by using a reporter gene mediated caspase-3 sensor in chemo sensitive and paclitaxel resistant ovarian cancer cells.
Materials and Methods:
A cellular model of paclitaxel resistance was developed in OAW42 cells stably expressing the caspase 3 sensor. The activity of caspase 3 after single and combinatorial drug treatments was determined using western blot and luciferase activity. Cell viability and cell cycle analysis were determined by MTT 3 (4,5- dimethyl thiazol-2 yl-2,5- diphenyl tetrazolium bromide (MTT) and Flow cytometric analysis (FACS) analysis. High Performance Liquid Chromatography (HPLC) analysis was performed to assess cellular uptake of the propanediones.
Results:
Both nitro/methoxy (Group I) and halogen substituted propandiones at ortho, meta and para positions (Group II) showed a moderate increase in caspase-3 activity by 1.5- to 3.3-fold as compared with controls. However, no noticeable change in apoptotic cells percentage was observed. Increased intracellular uptake of Paclitaxel was observed during combinatorial treatment with one of the propanediones (PR2). Intriguingly, PR2 alone or in combination with Paclitaxel could induce a 2.5- to 2.9-fold increase in caspase-3 activity in Paclitaxel resistant cells.
Conclusion:
Our study reports a new class of propanediones that can augment the cytotoxic effect of Paclitaxel, and potentially can be used for treating Paclitaxel-resistant cancers.

Introduction:
Developing novel strategies to increase the efficacy of chemotherapy is an urgent need. We investigated the impact of combination therapy with docetaxel, or vinblastine with tamoxifen in inhibition of proliferation and induction of apoptosis in MDA-MB-231 and H1299 cells.
Materials and Methods:
Cell proliferation was assessed by MTT assay and the percentage of apoptotic cells was measured using DAPI staining. Statistical Analysis: Statistical analysis was performed by one-way ANOVA using SPSS software.
Results:
Vinblastine or docetaxel induced higher percentage of apoptosis in MDA-MB-231 cells than H1299 cells (
P
< 0.05). Tamoxifen exhibited the highest percentage of cell death in H1299 cells (
P
< 0.05). Treatment of both cell lines with combination of docetaxel and vinblastine or tamoxifen showed enhanced apoptotic and anti-proliferative effects (
P
< 0.05).
Conclusion:
Combination therapy of breast and lung cancer cell lines using docetaxel or vinblastine with tamoxifen synergistically increases the anti-proliferative affect of single agents.

Background:
To estimate the level of lipid peroxidation product (MDA) and the activities of antioxidative enzymes superoxide dismutase (SOD) and the correlation of these parameters in Oral Submucous fibrosis (OSF).
Aims:
Estimation of MDA and SOD levels in OSF patients and controls.
Settings and Design:
Patients above 15 years of age, who were diagnosed as OSF based upon thorough history, clinical examination and histopathological examination without any underlying systemic diseases, were included in the present study. Equal number of healthy subjects without any deleterious habits and without any clinically obvious oral lesions or systemic diseases were selected as the control group.
Materials and Methods:
The estimation of MDA in serum was done by thiobarbituric acid reactive species method. SOD was assayed by inhibition and autoxidation of adrenaline method.
Statistical Analysis Used:
The data were analyzed with Student's t-test.
Results:
Comparison of MDA, SOD among the OSF group and control group showed statistically significant increased levels of malondialdehyde and decreased levels of superoxide dismutase among the OSF groups. Significant changes were not seen in MDA and SOD levels between the different grades of OSF.
Conclusions:
From the present study, estimation of lipid peroxidation like MDA was done, which showed increased levels in the OSF group compared to the control group and antioxidant enzyme levels like SOD showed decreased levels in the OSF group compared to the control group. These can be considered as a subject of interest for their possible role in many of the precancerous and cancerous conditions.

PMID

Our understanding of the association between synovial sarcoma and peripheral neurolymphomatosis is limited to a few case reports in literature. Delay in diagnosis or misdiagnosis is possible due to its insidious onset and varied presentation compounded by non-specific imaging findings. Needle biopsy also may not be confirmatory especially, in cases of biphasic sarcoma as in our case, and it may be necessary to proceed to open biopsy. Here, is a case of a non-tender right calf muscle mass, which was reported as biphasic synovial sarcoma by FNAC. Positron emission tomography computed tomography - computed tomography (PETCT) showed right sciatic nerve involvement and multiple infra diaphragmatic lymph nodal lesions. Intensity of
18
F FDG (
18
Flourine labeled fluro de oxy glucose) uptake and the infra diaphragmatic lymph nodal lesions distribution, was more in favour of a lymphoma diagnosis rather than a sarcoma, (which are usually low metabolically active tumors). Thus, this case highlights the usefulness of FDG PETCT in arriving at a diagnosis in the background of indeterminate clinicopathological and radiologic findings.

Malignant melanoma has been reported to affect all organs of the human body with the metastasis. Stomach metastases are quite rare in cases of the most commonly reported primaries including, melanoma and breast, and lung carcinomas. This report involves, a 56-year-old man suffering from melanoma of the lower extremity that developed into gastric, pulmonary, and brain metastases. The patient who experienced epigastric pain with suspicious melanoma was referred to undergo endoscopy. A black and white ulcer with dimensions of 1 × 1.5 cm and a mass of 1 × 2 cm mass were found at D1 and lesser curvature. Physical examination revealed a 2 × 3 cm black lesion at his right heel. Pathologic examination provided multiple pieces of creamy soft-tissue measuring 0.3 × 0.2 × 0.1 cm showing pigmented tumor cells in lamina propria. Staining biopsy samples with anti-HMB-45 and Fontana demonstrated a higher degree of positivity in tumor cells. The patient was admitted to the hospital, but unfortunately his general conditions were deteriorated and he developed convulsion and deceased four days after admission.

Castleman's disease (CD) or giant node hyperplasia is a rare benign disease of unknown etiology characterized by lymphoid hyperplasia. Although the most common site of the disease is the mediastinum, very few cases occurring in lymph nodes elsewhere have been reported in English literature, including only 10 intramuscular cases. We report a case of unicentric CD of the hyaline vascular type in a 30 year female located in the right scapular region. This case has been reported due to its extreme rarity and also highlights the need for including CD in the differential diagnosis of soft-tissue tumors.

Lyell's syndrome or toxic epidermal necrolysis (TEN) is a life threatening complication mostly caused by medications, characterized by desquamative lesions of the skin and mucous membranes with 30 percent or more epidermal involvement along with mucus membrane. We report a rare case of toxic epidermal necrolysis following administration of docetaxel, a semi-synthetic taxane. A female diagnosed as having metastatic breast carcinoma received chemotherapy in form of docetaxel after being exposed to adjuvant chemotherapy, developed severe involvement of skin and mucus membrane. Diagnosis of TEN was made and she was managed with steroids, antibiotics, intravenous fluids and antiseptic dressings. Common toxicities reported with this drug include myelosuppression, alopecia, nail damage, erythema multiforme major and neuropathy. We believe this is the first case report of Lyell's syndrome following docetaxel. Main aim of this case is to make physicians aware of the severe skin reactions with docetaxel, measures to avoid them, early recognition and prompt treatment.

The liver is the most frequent site of metastases in colorectal cancer. Commonly used anticancer drugs in colorectal cancer are 5-fluorouracil, oxaliplatin and irinotecan 5-fluorouracil (5-FU) and oxaliplatin have very few numbers of studies that support their safety in hepatic dysfunction, but pharmacokinetic studies of anticancer drugs focused on the single-agents; however, there is lack of data about drug combinations such as 5-fluorouracil leucovorin and oxaliplatin (FOLFOX) and 5-fluorourocil, leucovorin and irinotecan (FOLFIRI) regimens. We demonstrated one patient with colorectal cancer and severe liver dysfunction secondary to hepatic metastases. Laboratory investigation on admission showed total bilirubin 22.5 mg/dl, alkaline phosphatase 1137 IU/l, aspartate amino transferase 254 IU/l, alanine aminotransferase 164 IU/l and carcinoembryonic antigen levels 863 ng/ml. We initiated a 5-FU/oxaliplatin-based combination chemotherapy. Our data supports the safety and feasibility of FOLFOX regimen in patients with severe liver dysfunction secondary to liver metastases of colorectal cancer.

Lymphoid hyperplasia of the gall bladder is an extremely rare condition that may be missed on associated radiological or clinical evaluation but is diagnosed on biopsy. We are reporting hereby, a case of reactive lymphoid hyperplasia masquerading as a lymphoma on histopathology. A 58-year-old male was referred to our hospital with complaints of pain abdomen infrequently since last one year. Ultrasonography revealed the presence of single calculus along with features of chronic cholecystitis. Laparoscopic cholecystectomy was performed and the gall bladder was sent for routine histopathological evaluation. On microscopic examination, there were sheets of cells, lymphoid in origin and numerous lymphoid follicles spread throughout the wall of the gall bladder. It was diagnosed as a case of reactive lymphoid hyperplasia with chronic cholecystitis on histopathology.

Advanced gall bladder cancer generally has a poor prognosis and also shows decreased response to conventional therapies like chemotherapy and radiotherapy. Though surgical resection is the most common approach followed, the 1-year survival rate is only 10%. Herein, we report the outcome of administration of autologous natural killer cell and activated T lymphocyte-based autologous immune enhancement therapy (AIET) in a case of gall bladder cancer stage IV which was progressing in spite of surgical resection and several sittings of chemotherapy. There were no adverse reactions after AIET. After three infusions of AIET, an improvement of the quality of life and general condition which is sustaining for more than 6 months and a substantial decrease in the CA 19-9 marker levels from 2938.22 U/mL before AIET to 511 U/mL, 5 months after AIET, in our experience make us recommend AIET along with other conventional treatments in similar cases.

Primary ovarian non-Hodgkin lymphoma (NHL) is rare and accounts for 0.5% of all NHLs. Here, we present a case of primary bilateral ovarian NHL in a six-year-old girl. The patient presented with lower abdominal pain and difficulty in walking. Subsequent ultrasonography and computed tomography revealed bilateral ovarian mass. The diagnosis of NHL was established after bilateral adnexectomy and histologic study of excised tissue. After thorough immunohistochemical evaluation, the tumor was diagnosed as Burkitt's lymphoma (Peripheral/Mature B cell neoplasm, Burkitt type according to WHO classification). The patient received 4 cycles of CODOX-M regimen. Six months follow up after surgery is unremarkable.

Primary malignant melanoma of urethra is an extremely rare entity. It has very poor prognosis. A 62-year-old post-menopausal female presented with complaints of voiding difficulty and a mass projecting from external urethral meatus. External genital examination revealed a growth arising from urethral meatus with blood-stained discharge from its surface. Biopsy from lesion confirmed the diagnosis to be malignant melanoma. Metastatic work up for the malignancy was negative. We describe the surgical management of this pathology at our tertiary care center and discuss the various treatment options possible in this scenario.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. Tyrosine kinase inhibitors (TKIs), such as imatinibmesylate, have been used for the adjuvant treatment of KIT-positive GISTs. Several pathologic changes after imatinib treatment of metastatic GIST including tumor necrosis, myxohyaline or sclerohyalinestroma, proliferative index decline, a varying degree of hemorrhage, edema, and cystic change have been reported in previous studies. More specifically, cystic changes after imatinib treatment were mainly induced by necrosis, hemorrhage, and degeneration. Until now, there have been no reports of cystic changes due to a dilated bile duct entrapped by a totally regressed tumor. We report a case of a 61-year-old man who was diagnosed with high-risk GIST of the stomach complicated by hepatic metastasis and who had such a unique pathologic changes with imatinib treatment.

Proliferating trichilemmal tumor (PTT) is an uncommon appendageal skin tumor that affects mainly elderly women. It arises from the external root sheath of the hair follicle and is most commonly observed on the scalp. Although most cases pursue a favorable clinical course and surgical excision is curative, malignant transformation has rarely been reported in these lesions. Because of limited number of cases reported in the literature, management of malignant PTT is controversial and mainly entails wide local excision. Many other adjuvant modalities have been tried. In this report, we present a case of malignant PTT in a 65-year-old male patient who presented with ulceroproliferative growth over occipital region since 4 months.

Malignant transformation of mature cystic teratoma (MCT) is a rare phenomenon with incidence of approximately 1-3%. We report a 48-year-old woman who presented to the emergency room with symptoms of bowel obstruction. She underwent computed tomography scan for the evaluation of obstruction, which demonstrated diffuse ascites accompanying a cystic pelvic to lower abdominal mass which had invaded into the adjacent small bowel causing partial small bowel obstruction. Histologically, the mass demonstrated a MCT within which aroused a well-differentiated squamous cell carcinoma. Exploratory laparotomy was performed to confirm the diagnosis and debulking of the mass was performed.

We present a very rare, interesting case of a carcinoma of the pancreas with predominantly abundant clear cell morphology. According to the WHO classification, primary clear cell carcinoma of the pancreas is classified as a rare "miscellaneous" carcinoma. The tumor was observed in the distal body and tail of the pancreas of a 74-year-old woman. The histopathology of tumor cells showed well-defined cell membranes, clear cytoplasm, and prominent cell boundaries. Immunohistochemical (IHC) staining showed positive reactions to antibodies against vimentin, cytokeratin 7 (CK-7), mucicarmine (MUC-1), periodic acid-Schiff (PAS), periodic acid-Schiff with diastase (PASD), carcinoembryonic antigen (CEA), and Carbohydrate Antigen 19-9 (CA 19-9). On the other hand, IHC staining was negative for alpha-fetoprotein (AFP), cytokeratin 20 (CK-20), HMB45, chromogranin, and synaptophysin. The patient was subsequently diagnosed with a primary solid-type pancreatic clear cell carcinoma with hepatic metastasis. Herein, we report this rare case and include a review of the current literature of this tumor.
