Management and prognosis of multiple myeloma.
Patients with asymptomatic or smoldering multiple myeloma should not be treated but should be observed closely for progression. For symptomatic myeloma, chemotherapy is indicated. Melphalan, the agent of choice, should be given with prednisone for 1 week of every 6 weeks, If melphalan brings no response, or response and then relapse, cyclophosphamide (Cytoxan) should be give intravenously every 4 weeks or orally every day. BCNU, CCNU, and doxorubicin (Adriamycin) have also shown activity in myeloma. Hypercalcemia occurs in one-third of patients and should be countered with hydration, corticosteroids, Neutra-Phos, or mithramycin. Long-term hemodialysis has achieved some success. The combination of sodium flouride and calcium carbonate produces new bone formation; it seems a useful adjunct in treatment for myelomatous bone disease. Radiation should be utilized only for severe, localized pain or for solitary lesions. Survival with multiple myeloma varies, mean durations being 2 to 3 years. Multivariate analysis indicates that serum creatinine and calcium levels are the most significant indicators regarding 2-year survival. We have found monoclonal proteinuria not significantly more frequent with renal insufficiency than with normal renal function, renal insufficiency not significantly more frequent with lambda than with kappa chains, and survival not significantly greater with IgG myeloma than with IgA.
