Résumé

Treatment of mantle cell lymphoma (MCL) in younger patients remains a challenge. We report results of a phase 2 trial using cytarabine and rituximab as induction regimen before autologous stem cell transplantation. Patients younger than 66 years with stage 3 or 4 MCL were included. Treatment consisted of 3 courses of CHOP(21) with rituximab at the third one and 3 of R-DHAP. Responding patients were eligible for autologous stem cell transplantation with TAM6 or BEAM. Sixty patients were included. Median age was 57 years. Characteristics of patients were: BM involvement 85%, leukemic disease 48%, gastrointestinal involvement 52%, Performance Status > 16%, lactate dehydrogenase > 1N 38%, Mantle Cell Lymphoma International Prognostic Index (low 55%, intermediate 38%, high 13%). The overall response rate was 93% after (R)-CHOP and 95% after R-DHAP. Although uncommon after (R)-CHOP (12%), 57% of patients were in complete response after R-DHAP. With median follow-up of 67 months, median event-free survival is 83 months, and median overall survival is not reached. Five-year overall survival is 75%. Comparison with a previous study without rituximab shows improvement of outcome (median event-free survival, 51 vs 83 months). No toxic death or unexpected toxicities were observed. This study confirms that induction with rituximab and cytarabine-based regimens is safe and effective in MCL patients. This regimen is currently compared with R-CHOP(21) induction in a multicentric European protocol.
