The value of splenectomy in chronic lymphocytic leukemia.
Between January 1, 1980, and July 31, 1985, 168 patients were treated at our institution for chronic lymphocytic leukemia (CLL). Splenectomy was performed on 32 (23 men and 9 women). The mean age of these surgical patients was 59.4 years (range, 43-75). Twenty-four patients had received chemotherapy and/or corticotherapy prior to surgery and 1 of these 24 also underwent splenic radiotherapy. The interval between diagnosis and splenectomy ranged from 1 to 108 months (mean, 33.6 months +/- 28.6). Before splenectomy, 9 patients had platelet counts greater than 100,000/mm3 (3 with normal counts), 18 had counts between 50,000 and 100,000/mm3, and 5 had less than 50,000/mm3. Seven patients had anemia with hemoglobin levels less than 10 g/dl (3 associated with thrombocytopenia); in the other 25 patients, hemoglobin levels were between 10 and 11 g/dl in 12 (9 associated with thrombocytopenia) and greater than 11 g/dl in 13. All patients but one had splenomegaly (mean spleen weight 1780 g +/- 938.7 range, 160-4300 g). One postoperative death was recorded. Postoperative morbidity occurred in 7 of 31 cases; severe infection was never observed. The average duration of hospitalization was 15 +/- 4.7 days (range, 9-28). Twenty-two of the 23 patients with thrombocytopenia less than 100,000/mm3 had complete remission after splenectomy. One had a partial remission that was later completed by means of drug therapy. Two patients relapsed within 6 months and one after 32 months. All but two cases of anemia responded to splenectomy; one patient relapsed. In 15 of 31 surviving patients, further treatment was required within a few weeks or months after surgery. Five patients died at 8, 17, 22, 26, and 35 months, respectively. The other 26 patients are alive and well with a mean follow-up of 34 months (range, 11-71 months). Splenectomy may be an effective treatment for CLL patients with splenomegaly, thrombocytopenia, and/or anemia.
