RCHOP and RDHAP Followed by Autologous Stem Cell Transplantation (ASCT) in Mantle Cell Lymphoma (MCL) : Final Results of a Phase II Study from the GELA

Abstract Introduction: Treatment of mantle cell lymphoma (MCL) in younger patients (pts) is still a challenge, with questions about best induction regimen before autologous stem cell transplantation (ASCT) and impact of Rituximab. We report here the final results with extended follow-up of a prospective phase II trial. Methods: Patients under 66 years with histologically proven, stage III-IV, MCL were included. Treatment consisted of three courses of CHOP with Rituximab at the third one and three courses of RDHAP. Peripheral blood stem cells harvest was performed and responding pts were eligible for an ASCT after high dose radio-chemotherapy with TAM6 (TBI 10 Gy, Aracytine 6 g/m², Melphalan 140 mg/m²) or BEAM if TBI could not be performed. Results: From May 2000 to September 2003, 60 pts were included. Median age was 57 years. Characteristics of patients were as follow : bone marrow involvement 85%, leukemic disease 48%, gastrointestinal involvment 52%, PS>1 6%, LDH > 1N 38%. Overall response rate was high with 93% after (R)CHOP and 95% after RDHAP. Interestingly, CR was uncommon after (R)CHOP (12%), whereas high proportion of patients (61%) were in CR after RDHAP, suggesting higher efficacy of high dose AraC. Forty-nine pts were autografted (41 with TAM6) : all patients but two (96%) were in CR. With a median follow-up of 67 months, median EFS was 83 months and median OS was not reached. Five years OS was 75%. Neither toxic death nor unexpected toxicities were observed. The comparison with our previous French oligocentric study using the same regimen but without Rituximab (Lefrere, Hematologica 2007) suggests a better outcome when Rituximab is added (median EFS : 51 months). Conclusion: This study confirms that regimens containing Aracytine and Rituximab are safe and prolong survival and may even induce cure in MCL patients. Thus, they should be used in induction treatment before ASCT. This regimen is currently compared with the classical RCHOP induction in a multicentric European protocol within the EMCL network.

Abstract Introduction: Mantle cell lymphoma (MCL) is a mature B-cell lymphoma comprising up 5% of non-Hodgkins lymphomas. Although the prognosis for MCL patients has improved in recent years, the outlook for those with advanced or recurrent disease remains poor and the role of hematopoietic stem cell transplantation is unclear. The HyperCVAD-M/A regimen (fractionated high-dose cyclophosphamide, vincristine, doxorubicin and prednisolone alternated with methotraxate and cytarabine) has yielded encouraging results when combined with autologous stem cell transplantation (ASCT). In an effort to improve these results further, we have combined rituximab in vivo purging and post-transplant consolidation with HyperCVAD-M/A plus ASCT. Methods: Patients aged <65 years with previously untreated or relapsed MCL were treated with four courses of HyperCVAD-M/A followed by four once-weekly doses of rituximab 375mg/m2 as purging prior to stem cell mobilization and harvesting, high-dose chemotherapy (ICT-CY or BEAM), stem cell reinfusion and four further doses of rituximab immunotherapy post-transplant. Results: Of the 40 patients enrolled so far, 20 (15 male, 5 female; 18 previously untreated) have been transplanted. The median age was 50 years (range 38–63 years). After the final post-ASCT immunotherapy all 20 patients were in clinical complete remission. With a median follow-up of 36 months from diagnosis (range 7–64 months), 18 patients remain alive with 13 in complete remission. One patient died 15 months post-ASCT without evidence of disease recurrence. Kaplan-Meier estimates of 5-year overall and event-free survival are 90% and 65% respectively. Conclusions: This approach seems safe and feasible and produces durable remissions; longer follow-up of a more patients will be required to assess the effect of the procedure on survival.

Abstract Introduction: Mantle cell lymphoma (MCL) is a CD20+ malignancy comprising up 5% of non-Hodgkin’s lymphomas, and has a poor prognosis under standard chemotherapy. The HyperCVAD-M/A regimen (fractionated high-dose cyclophosphamide, vincristine, doxorubicin and prednisolone alternated with methotraxate and cytarabine) has yielded encouraging results when combined with autologous stem cell transplantation (ASCT) in MCL, with 5-year failure-free survival of 54% and overall survival 72%. In an effort to improve these results further, we have combined rituximab in vivo purging and post-transplant consolidation with HyperCVAD-M/A plus ASCT. Methods: Patients aged <65 years with previously untreated or relapsed MCL were treated with four courses of HyperCVAD-M/A followed by four once-weekly doses of rituximab 375mg/m2 as purging prior to stem cell mobilization and harvesting, high-dose chemotherapy (ICT-CY or BEAM), stem cell reinfusion and four further doses of rituximab immunotherapy post-transplant. Results: Of the 34 patients enrolled so far, 15 (12 male, 3 female; 12 previously untreated) have been transplanted. The median age was 52 years (range 47–63 years). After the final post-ASCT immunotherapy all 15 patients were in clinical complete remission. With a median follow-up of 30 months from diagnosis (range 7–52 months), 14 patients remain alive with 13 in first complete remission. One patient died 15 months post-ASCT without evidence of disease recurrence. Kaplan-Meier estimates of 4-year overall and event-free survival are 93.3% and 86.6% respectively. Conclusions: This approach seems safe and feasible and produces durable remissions; longer follow-up of a more patients will be required to assess the effect of the procedure on survival.
