Between February 1972 and February 1989, splenectomies were performed in 30 patients with chronic lymphocytic leukemia (CLL) and three with prolymphocytic leukemia (PLL) at our institution. Indications for splenectomy included anemia and/or thrombocytopenia (hypersplenism) in 31 patients and symptomatic splenomegaly in two patients. Median time from the diagnosis of CLL to splenectomy was 25 months. Twenty (87%) of the 23 patients splenectomized for thrombocytopenia with or without anemia had platelet increments of greater than or equal to 50 x 10(9)/liter. Hemoglobin increments of greater than or equal to 3 gm/dl were noted in 12 (71%) of 17 patients splenectomized for anemia with or without thrombocytopenia. The median duration of platelet response was 18 months for 19 evaluable patients, and the median duration of hemoglobin response was 62 months for 10 evaluable patients. Median survival time from splenectomy was 36 months. Median survival from diagnosis was 103 months for 10 patients with stage III or IV disease at diagnosis and 79 months for 10 patients with stage II. A prospective study of the effect of splenectomy in a larger number of patients with advanced CLL should be considered.
