A comparative study of CHOP versus MEVP (mitoxantrone, etoposide, vindesine, prednisolone) therapy for intermediate-grade and high-grade non-Hodgkin's lymphoma: a prospective randomized study.

: To evaluate a new combination chemotherapy with mitoxantrone (MXT), etoposide (VP-16), vindesine (VDS), and prednisolone (MEVP therapy) as a front-line chemotherapy for non-Hodgkin's lymphoma (NHL), a prospective randomized study comparing this therapy (28 patients) with CHOP therapy (29 patients) was conducted in 57 patients with intermediate-grade or high-grade NHL with stages II-IV. The MEVP therapy consisted of 10 mg/m2 of MXT intravenously on day 1, 2 mg/m2 of VDS intravenously on day 1, 200 mg/m2 of VP-16 orally on days 1-3, and 40 mg/m2 of prednisolone orally on days 1-5. This regimen was repeated every 3 weeks for up to 10 courses. Complete responses (CR) were achieved in 17 (63.0%) of the 27 evaluable patients treated with MEVP therapy, and in 20 (71.4%) of the 28 evaluable patients treated with CHOP therapy. Relapse-free survival rates and overall survival rates at 3 years were 58.8% and 46.4%, respectively, for the MEVP group and 70.0% and 54.0%, respectively, for the CHOP group. Granulocytopenia was more severer and associated infection episodes were more frequent in the MEVP group. MEVP therapy was effective as a front-line chemotherapy for intermediate- and high-grade NHL, although it was not superior to CHOP therapy in treatment effect and was not less toxic than CHOP.
