Combined chemotherapy with carmustine, doxorubicin, etoposide, vincristine, and cyclophosphamide plus mitoxantrone, cytarabine and methotrexate with citrovorum factor for the treatment of aggressive non-Hodgkin lymphoma: a long-term follow-up study.

BACKGROUND: The standard treatment for patients with aggressive non-Hodgkin lymphoma (NHL) is cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). Since 1989, the authors have used a new chemotherapy regimen with combined carmustine, doxorubicin, etoposide, vincristine, and cyclophosphamide plus mitoxantrone, cytarabine and methotrexate with citrovorum factor called BAVEC-MiMA. The objective of the current study was to explore, after a long follow-up period, the impact of this third-generation regimen for the treatment of aggressive NHL.

METHODS: One hundred and one consecutive patients (median age, 41 years) with either B-cell (n=94 patients) or non-B-cell (n=7 patients), aggressive lymphoma were diagnosed and treated between 1989 and 1999 with the BAVEC-MiMA regimen.

RESULTS: The complete response rate was 74%, and the overall response rate was 89%. Eleven patients with refractory disease died rapidly after a median period of 5 months. The major toxicity was Grade 4 neutropenia (according to World Health Organization criteria), which was observed in 15 patients (15%). There were four toxicity-related deaths. The overall survival rate was 63% at 9 years. In multivariate analysis, factors that were associated with advantage in overall survival were response to induction therapy, bulky disease, and high score on the International Prognostic Index (IPI). The disease-free survival rate was 77% at 9 years. In multivariate analysis, the IPI was the most important variable for the definition of disease-free survival.

CONCLUSIONS: The BAVEC-MiMA regimen was feasible on an outpatient basis, it was tolerated well, and it showed a low toxicity-related mortality. The long follow-up in patients with NHL, which is a rapidly fatal disease, led the authors to observe that, with this regimen, a cure was obtained in > 50% of patients who had low-risk or low-to-intermediate-risk, aggressive NHL.
