[Diagnosis and therapy of multiple myeloma: current aspects].
The crucial first step in management of multiple myeloma is to be certain regarding the diagnosis. Multiple myeloma must be distinguished from monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma. Therapy should be administered to patients with advanced and active myeloma involving anemia, osteolysis or renal failure. Chemotherapy with a single agent (melphalan) is the preferred initial treatment for overt, symptomatic multiple myeloma. Cytostatic drug combinations produce a higher response rate, but survival and remission during are the same compared with melphalan/prednisone therapy. However, in patients with renal failure and/or poor prognostic factors (advanced stage, elevated beta 2-microglobulin, high bone marrow plasma cell labeling index, high levels of C-reactive protein and lactate dehydrogenase and/or nodular pattern of bone marrow infiltration), combined treatment with adriamycin, vincristine and prednisone should be administered to prevent nephrotoxicity and attain a rapid paraprotein decrease. Alpha interferon treatment as maintenance seems to prolong the duration of the plateau state after response to chemotherapy, but apparently does not prolong survival. Allogeneic bone marrow transplantation involves significant early mortality (50%); the risk of graft versus host disease, infections and renal failure is a problem, and relapse is common. High dose chemotherapy followed by autologous bone marrow transplantation or peripheral blood stem cell reinfusion may prolong survival and free time to progression, but, to date, there are no indications of cure. This therapeutic procedure, therefore, should be considered for randomized trials for young patients with poor prognostic factors.
