Since 1987, the GELA has initiated multicenter prospective trials for aggressive non-Hodgkin's lymphomas (NHL). Lymphoblastic lymphomas (LBL) were included in those studies until 1997, and 92 LBL patients under 61 years were identified after histological review. The protocols prescribed high-dose anthracycline regimens, four cycles given every 15 days as induction and lasted for ≤6 months. A total of 23 patients underwent high-dose therapy consolidation followed by autologous stem-cell transplantation and 69 received standard chemotherapy regimens. Clinical characteristics showed a male predominance (66%) with a median age of 31 years, bone marrow (BM) involvement (22%), mediastinal involvement (66%) and elevated LDH (62%). At the end of treatment, it was seen that 71% of the patients achieved complete remission; four (4%) patients died during induction; 43 patients relapsed at a median time of 10 months. With a median follow-up of 34 months, the 5-year overall survival (OS) and event-free survival (EFS) rates were 32 and 22%, respectively. The only favorable factor significantly associated with survival was young age. These results are poorer than those obtained in other aggressive lymphomas treated with the same regimens and suggest that adult LBL patients should be treated with acute lymphoblastic leukemia protocols.
