Prolymphocytic leukemia. Serial responses to therapy.

Prolymphocytic leukemia is a rare lymphoproliferative disorder characterized by marked lymphocytosis, massive splenomegaly, minimal lymphadenopathy, and poor prognosis. Previous reports have noted very short survival, and poor response to single agent alkylator chemotherapy. A small number of reports have shown response to combination chemotherapy regimens including Adriamycin (doxorubicin). A case of prolymphocytic leukemia with serial responses to combination chemotherapy and splenectomy resulting in significant prolongation of survival is reported.
