VBAMDex chemotherapy in advanced multiple myeloma.

In a phase II study 28 patients with advanced multiple myeloma were treated with a five drug regimen consisting of vincristine, BCNU, adriamycin, melphalan and dexamethasone. 11 out of 13 patients without prior chemotherapy showed significant remissions (greater than 25% tumor cells mass reduction), 7 of them had more than 75% TCM reduction. Out of 15 additional patients resistant to previous chemotherapy, 13 had significant remissions, including 9 patients with greater than 75% TCM reduction. No tumor progression was observed in either group of patients. The median follow-up of all patients was 12.75 months. 4 patients relapsed. Toxicity mainly related to the bone marrow was observed in 14 patients. This regimen might offer a promising alternative for the treatment of advanced multiple myeloma, but still has to be tested in a prospective randomized trial.
