ABSTRACT
We have carried out a retrospective analysis of 490 non-Hodgkin's lymphomas (NHLs), followed at our clinic, with the purpose of evaluating the clinicopathologic features of these patients. The patients were assessed with regard to their characteristics including age, gender, histologic distribution, stage, extranodal involvement, presenting symptoms, and biopsied site. Of the patients 314 (64%) were male and 176 (36%) were female. The overall median age was 43 years (range 14-90). The patients were classified according to the Working Formulation (WF) system 71 (14.4%) were low grade, 342 (69.8%) were intermediate grade, 43 (8.7%) were high grade, and 34 (6.7%) had other lymphomas. Intermediate-grade non-Hodgkin's lymphomas formed the largest group, of whom 320 patients' paraffin blocks were available for Revised European and American lymphoma (REAL) classification 78% were B-cell lymphomas, whereas 16% were T/NK lymphomas. Six percent of cases were unclassified lymphomas. Diffuse large B-cell lymphoma (DLBCL) was the most commonly observed histopathologic type in 132 (41%) patients. Extranodal involvement was found in 218 (44.5%) patients. The most commonly affected extranodal sites were small bowel, stomach, and tonsil in 72 (33%), 63 (29%), and 19 (8.7%) patients, respectively. According to the Ann Arbor staging system, the vast majority of patients (89.4%) were advanced stage. In conclusion,The characteristics of NHLs in our region show some differences from the other sites of Turkey and the world.
