Abstract
67 previously untreated patients with multiple myeloma were entered on a randomized clinical trial to determine whether the use of combination chemotherapy including vincristine, carmustine, alkylating agents, and prednisone was more effective than conventional therapy with melphalan and prednisone. The treatment groups did not show significant differences with respect to major prognostic factors. With the 2-drug combination therapy and 5-drug combination therapy, 67 and 74% of the patients achieved remission, respectively. Moreover, no significant difference was found between the two treatment schedules in terms of median survival (30+ months). The survival curves for stage III patients treated with the two regimens did not differ significantly. After 12 months, patients who had achieved remission were randomized to have treatment discontinued or to have maintanence treatment. 7 of 15 patients on maintenance therapy relapsed, whereas 9 of 14 patients who had their therapy discontinued relapsed, and the survival of the two groups was similar.
