Abstract
In a randomised multicentre trial a combination of methylprednisolone, vincristine, CCNU, cyclophosphamide and melphalan (MOCCA) was compared with intermittent melphalan and prednisone (MP) as primary treatment in multiple myeloma. In the MP arm the refractory or relapsed patients were treated with regimen MOCCA. The MOCCA arm produced a response rate of 75% among 64 patients and the MP arm a respone rate of 54% among 66 patients. The median surival was 41 months in the MOCCA arm and 45 months in the patients primarily randomised to the MP arm. The initial response to MOCCA improved the survival, while this effect was not statistically significant in the MP arm. The results show that the median surivival does not increase if aggressive chemotherapy is employed as the first line treatment in multiple myeloma.
