Objective: Primary central nervous system lymphoma (PCNSL) is a rare form of aggressive extranodal non-Hodgkin lymphoma. This study attempts to delineate the clinicopathological and radiological profile of PCNSL cases at our center. Materials and Methods: All the pathologically confirmed PCNSL cases between January 2007 and July 2016 were analyzed retrospectively. The influence of potential prognostic parameters and therapeutic strategies on survival was investigated by log-rank test and Cox regression analysis. Results: Of the 53 PCNSL patients, 34 (64%) patients were males. Median age at diagnosis was 44 years (range 22–65 years). The most common location in the brain was the cerebral hemispheres in 32 patients (60%), and 16 patients (30%) had multiple intracranial lesions. Histologically, all patients were diffuse large B-cell lymphomas, except one case of anaplastic large-cell lymphoma. The median survival of the patients received whole-brain radiation alone (n = 6), standard CHOP chemotherapy + radiation (n = 14), and DeAngelis protocol (n = 31) was 8 months, 13 months, and 23 months, respectively. Among the 31 patients treated with DeAngelis protocol, Memorial Sloan Kettering Cancer Center Class 1 (n = 23) and Class 2 (n = 8) patients had a median overall survival (OS) of 25 months and 13 months, respectively. The incidence of treatment-related neurotoxicity was significantly higher with DeAngelis protocol, in comparison to CHOP + whole-brain radiation therapy (26% vs. 14%, P < 0.05). Conclusion: None of the potential prognostic factors had a statistically significant influence on OS in our patients. High-dose methotrexate-based chemotherapy combined with radiation was the only factor, which had a significant impact on survival (log-rank P = 0.000) but at the cost of increased neurotoxicity.
