DC Case
Fourteen consecutively referred, symptomatic patients with Waldenstrom's
macroglobulinemia (ages 52-87 yr) have been treated with the 5-drug M-2
protocol (BCNU, cyclophosphamide, vincristine, melphalan, and prednisone).
Three patients were previously treated and 11 patients were untreated. The
majority of patients were symptomatic from hyperviscosity. All patients
have responded to therapy. Two patients have achieved complete remissions
and 12 patients partial remissions to date. None of the patients with
symptomatic hyperviscosity has required plasmapheresis since therapy with
the M-2 has been initiated. Lymphadenopathy, hepatosplenomegaly, and anemia
have also responded to treatment. Follow-up data are limited, with survival
from initiation of therapy with the M-2 ranging from 2+ to 35% mo (median
17+ mo) 2+-40+ mo from time of diagnosis). Combination chemotherapy for
Waldenstrom's macroglobulinemia with the M-2 protocol appears to increase
the response rate in patients with symptomatic disease. Further survival
analysis will be carried out.
