Abstract
In a randomized study with 234 previously untreated patients with multiple myeloma, 129 were treated with melphalan (8 mg/m2 perorally for four days) and prednisone (40 mg/m2 perorally for seven days, both every four weeks) and 105 with melphalan and prednisone at the same doses plus cyclophosphamide (600 mg/m2 intravenously every four weeks), MeCCNU (100 mg/m2 PO every eight weeks), and vincristine (MPCCV, 0.6 mg/m2 IV every four weeks). A total of 49 (38%) of the 129 patients treated with melphalan and prednisone (MP) and 48 (46%) of the 105 patients treated with MPCCV showed good response (GR) (P not significant); the overall response rates were 58% and 70%, respectively. Thirty-seven percent of the MP group and 39% of the MPCCV group remain alive at 48 months from first treatment (P not significant). The estimated 48-month survival from first treatment, according to different prognostic factors at diagnosis, in both groups was as follows: stage 1,56%; stage II, 46%, and stage III, 23% (I and II v III P less than .001). Survival at 48 months according to response was GR, 68%; partial response (PR), 33%; and null, 16% (GR v null, P less than .0005; GR v PR, P less than .0005). Survival according to renal function was 43% for a creatinine level less than 2 mg/100 mL and 27% for a creatine level greater than or equal to 2 mg/100 mL (P less than .0005). No significant difference has been found between the two treatment schedules in terms of response rate and survival time, in any stage of disease.
