Abstract: Primary central nervous system lymphoma (PCNSL) is defined as the involvement of brain, leptomeninges, eyes or spinal cord by
non-Hodgkin lymphoma. The role of various prognostic markers in predicting adverse outcome is debated. Objectives: To investigate the
clinical and immunohistochemical findings of immunocompetent PCNSL cases (39 cases) diagnosed at the study center, and evaluate the
influence of potential prognostic factors on overall survival (OS) of patients. Methods: Data regarding patient characteristics, neuroimaging,
pathological and immunohistochemical features and follow-up were obtained from patient records. The influence of potential prognostic
parameters on OS was investigated by log-rank test and Cox regression analysis. Results: Patients who received combined chemotherapy
and radiotherapy had a significantly better OS when compared to chemotherapy alone. Other variables included in this study were not
associated with a significant survival advantage. Conclusion: In this study, we failed to demonstrate a relationship between different
clinicopathological variables and OS of patients. Prospective studies with large patient series are needed to investigate other potential
prognostic factors. (IJCEP1303033).
