ALTERNATING COMBINATION CHEMOTHERAPY (VMCP/VBAP) IS NOT SUPERIOR TO MELPHALAN PREDNISONE IN THE TREATMENT OF MULTIPLE-MYELOMA PATIENTS STAGE-III - A RANDOMIZED STUDY FROM MGCS

86 previously untreated patients with multiple myeloma stage III entered a randomized trial comparing combination chemotherapy (VMCP/VBAP) (n = 42) with intermittent oral melphalan and prednisone (MP) treatment (n = 44). The treatment gropus were well comparable with regard to major prognostic factors. There was no statistically significant difference in the response rates, 52% (VMCP/VBAP) vs 61% (MP); in the response duration times, median 19 months vs 22 months, or in the survival times, median 24 months vs 28 months. However, survival of patients older than 65 years was significantly shorter in the VMCP/VBAP group (median 15 months) compared to the MP group (median 23 months) (p = 0.03). No significant difference in non-hematological or hematological toxicity was noted. The study further supports the notion that MP therapy should be used as primary standard treatment for patients with multiple myeloma.
