Non-Hodgkin's Lymphoma Protocols in the Treatment of Patients with Burkitt's Lymphoma and Lymphoblastic Lymphoma: A Report on 58 Patients

Abstract

Lymphoblastic lymphoma (LBL) and Burkitt's lymphoma belong to the very aggressive lym-phomas requiring intensive therapy. We retrospectively analyzed 29 patients with Burkitt's lymphoma and 29 patients with LBL who received induction therapy with a CHOP-like lymphoma protocol. Patients with Burkitt's lymphoma (with a median age of 54.5 years) have a CR rate of 72% and a lymphoma free long-time survival of 55%. The International Prognostic Index was the most valuable prognostic factor for survival. Patients with LBL with a median age of 45 years had a CR rate of 55% and a lymphoma-free survival of 38%. Stage was the most predictive prognostic factor. Our data suggest that for older patients (>50) treatment with lymphoma protocols may yield response rates that are comparable to the results of patients with disseminated diffuse large cell lymphoma. Younger patients with risk factors should be treated with more intensive therapy like ALL-protocols. The role of auto-transplantation after high dose therapy (HDT) however as part of primary treatment still needs to be evaluated in clinical trials. One of four patients with LBL who received HDT and one of four patients with Burkitt's lymphoma who received HDT achieved long-term remission.
