Background: Uterine cervical cancer constitutes a major proportion of cancer in females of our population. The objective of this study was to conduct a clinical study of uterine cervical cancers including their survival from hospital-cancer registry data. Materials and Methods: Data of uterine cervical cancer patients diagnosed from January 1, 2010 to December 31, 2010 and that were treated at a regional cancer center in North East (NE) India was recruited. The cases were analyzed for age group distribution, stage, and treatment types. Survival from the date of first diagnosis and hazard ratios (HRs) was estimated. Survival probability and HRs were calculated by Kaplan–Meier method and Cox-proportional regression analysis, respectively. Active follow-up was done for the survival analysis. Results: One hundred and ninety-three patients (53.4%) were included for the analysis. Median age was 48 years, 56.5% (108/193) of patients were in the age group of 45–64 years, 56.5% (109/193) were Stage II patients, radiotherapy alone was the main treatment modality in 65.8% (127/193) of cases, 5-year overall survival (OS) was 40.7%, median survival was 44 months, early staged and advanced stage patients had 47.7%, and 29.4% 5-year OS (P = 0.002), respectively, and HR for advanced stages was 1.8 (P = 0.003, confidence interval (CI) = 1.2 to 2.7). Conclusion: Describing the clinical characteristics and survival of uterine cervical cancer patients is important for planning and identifying the gaps for its control in the NE India.
