Achieved Platelet Counts Research Articles

Splenectomy for thrombocytopenia in chronic lymphocytic leukemia.

The role of peripheral platelet destruction as a reversible etiology of thrombocytopenia in chronic lymphocytic leukemia (CLL) was evaluated in nine patients with CLL and refractory thrombocytopenia who underwent splenectomy. The patients' ages ranged from 54 to 74 years. Progressive thrombocytopenia refractory to antineoplastic agents and corticosteroids had been present for a mean of 23.4 months. The platelet counts were 4,000-57,000/microliter, and were generally higher in those patients with larger spleens. The spleens ranged from 180 to 4050 gm. Seven patients responded completely to splenectomy, achieving platelet counts greater than 150,000/microliter, and in one other patient, the count rose to greater than 100,000/microliter. The platelet count of one patient failed to respond to surgery. Those patients with massive splenomegaly developed higher, more rapidly rising platelet counts postoperatively. No operative mortality was encountered. Median hospitalization was seven postoperative days. All patients experienced an increased sense of well-being. Median follow-up time is 9 months.
