The hyper-CVAD-rituximab chemotherapy programme followed by high-dose busulfan, melphalan and autologous stem cell transplantation produces excellent event-free survival in patients with previously untreated mantle cell lymphoma.
The hyper-CVAD + rituximab (R) programme consists of fractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone + R alternating with high-dose methotrexate + cytarabine (HD MTX/ARA-C) + R. This regimen, when used as initial therapy for patients under 65 years of age with previously untreated mantle cell lymphoma (MCL), results in remission rates of > 85% with a median event-free survival (EFS) of > 50 months, but with a pattern of continuous relapse out to 60 months. We performed a study of hyper-CVAD + R, followed by consolidative peripheral blood progenitor cells autograft [autologous stem cell transplant (AuSCT)] with high-dose busulfan and melphalan (Bu/Mel) conditioning, in patients with responsive disease. Thirteen patients with a median age of 54 (range = 33-61) were treated. Complete remission (CR) was achieved in 12 patients (92%) after hyper-CVAD + R and 12 completed AuSCT after Bu/Mel conditioning. One patient died during the autograft and another declined AuSCT after achieving a CR with hyper-CVAD + R. With a median follow-up from diagnosis of 36 months (range = 16-53 months), the observed 36 months overall survival and EFS are both 92% for the whole cohort. These data confirm the excellent CR rates achieved by the use of hyper-CVAD + R in patients with MCL and suggest that consolidation with Bu/Mel and AuSCT may improve durable disease control when compared to published outcomes of hyper-CVAD + R alone.
