m-BACOD chemotherapy for intermediate- and high-grade non-Hodgkin's lymphoma

A total of 92 patients with previously untreated intermediate- or high-grade non-Hodgkin's lymphoma attending the University Department of Medicine, Queen Mary Hospital, Hong Kong, were treated with the m-BACOD chemotherapy regimen (methotrexate, bleomycin, doxorubicin, cyclophosphamide, vincristine and dexamethasone). Additional involved-field radiotherapy was given to 32 (35%) patients. Myelosuppression was the major toxicity, and 5 (5%) treatment-related deaths occurred due to pneumonia, bleomycin sensitivity, doxorubicin cardiotoxicity and reactivation of hepatitis B infection. The overall complete response (CR) rate was 65/92 (71%) and the relapse rate was 22/65 (34%). The disease-free survival of the 65 CR patients at 2 years was 52% and the overall survival of all 92 patients at 3 years was 56%. The CR rate of stage I and II patients was significantly better than that of those with stage III and IV disease (87% vs 59%; P = 0.01), and the CR rate of stage III patients was superior to that of those with stage IV disease (86% vs 50%; P = 0.05). The overall survival of stage III and IV patients was significantly worse than that of subjects with stage I and II disease (31% vs 73%; P = 0.02). Multivariate analysis revealed that the independent prognostic variables significantly determining the CR rate and survival included the clinical stage and the serum lactate dehydrogenase level. From this study, the results of treatment with the m-BACOD regimen in patients with advance disease appeared to be similar to those obtained using the conventional CHOP regimen (cyclophosphamide, doxorubicin, vincristine and prednisone).
