Abstract
Information on presentation and outcome of B cell non-Hodgkin's lymphoma (B-NHL) is limited from developing countries. Data of newly diagnosed adult aggressive B-NHL (n = 260) patients were analyzed for clinical presentation, histological subtype, response to therapy, and survival. Univariate and multivariate Cox-regression analyses were performed for identification of prognostic factors. Diffuse large B cell lymphoma was the most common subtype (71 %). Median age was 50 years (18-78 years). The most common symptom was peripheral lymphadenopathy seen in 66 % of cases. Forty-seven percent of patients had advanced stage (stage III/IV), and 41 % had ECOG performance status of II-IV. B symptoms and bulky disease were present in 47 and 26 %, respectively. Intermediate to high risk score according to the International Prognostic Index (IPI) was seen in 67 %. Cyclophosphamide, adriamycin, vincristine, and prednisolone (CHOP) and CHOP-like regimens were used in 70 % cases, while R-CHOP was used in 18 % cases. For diffuse large B cell lymphoma (DLBCL) patients, in intent-to-treat analysis, the overall response and complete remission rates were 73 and 60 %, respectively. Four-year event-free and overall survival was 54 and 64.7 %, respec...Continue Reading
