Theaim of this study was to assess the epidemiological and histomorphological features and survival of affectedpatients in our center. Materials and Methods: The clinicopathologic features and outcome of 44 children andadolescents with non Hodgkin lymphoma diagnosed during 2004-2012, were investigated retrospectively. Theinfluence of potential prognostic parameters in overall survival was investigated by log-rank test and Coxregression analysis. Results: The mean age at presentation was 13.8±6.16 years with a male predilection (M:F=3:1). Malignant lymphoma, not otherwise specified, diffuse large cell lymphoma and Burkitt lymphoma werethe three most common histological types observed. The tumors were 36.4% intermediate grade, 27.3% highgrade and 34.1% belonged to the malignant lymphoma not otherwise specified group. Immunohistochemistryfindings were available in 39 cases. Out of these cases 33 (84.6%) had B cell lineage, 4 (10.25%) T cell lineageand 2 (5.12%) of the cases belonged to miscellaneous group. 3 year and 5 year survivals were 48% and 30%respectively and median survival was 36 months (95%CI=21.7-50.3 months). Overall survival in patients withhigh grade tumors was 19.5 months, in the intermediate group,79 months , and for malignant lymphomas nototherwise specified it was 33.6 months (p value=0.000). Conclusions: The survival rate for children and adolescentswith non Hodgkin lymphomas at our center during 2004-2012 was at a low level.
