Durable remission after splenectomy for Waldenström's macroglobulinemia with massive splenomegaly in leukemic phase.

Abstract

A patient with M-proteinemia (IgM, kappa type), lymphocytosis, anemia, and massive splenomegaly, was diagnosed as having Waldenström's macroglobulinemia (WM). Since this case was refractory to chemotherapy, splenic irradiation was performed, which effectively reduced the serum IgM level, spleen size, and lymphocyte counts; however, its effect was transient. Splenectomy was then carried out. The spleen contained abundant IgM-producing lymphocytes, and after splenectomy, the serum IgM values decreased and the peripheral blood counts returned to near normal. The transient increases of serum IgM occurred during two infectious episodes postoperatively. The patient has now been in a satisfactory remission for six years after splenectomy. The removal of an IgM-producing/secreting site and release from hypersplenism may be the major mechanisms involved in achieving the durable remission after splenectomy. In individual cases of WM with massive splenomegaly, we recommend splenectomy as part of the management of this disorder.
