Splenectomy for hematologic depression in lymphocytic lymphoma and leukemia.
Fifty patients with lymphocytic lymphoma and chronic lymphocytic leukemia underwent splenectomy for various combinations of anemia, thrombocytopenia, and leukopenia. All of these patients had advanced lymphoproliferative disease, and most had infiltration of bone marrow by neoplastic cells. Good response in all hematologic parameters was obtained in 27 of 48 evaluable patients. An additional 13 patients responded in one or two parameters; there were only 8 complete failures. The over-all surgical mortality was 8%. The median duration of response was 4 months, and the mean, 7 months. Increased tolerance to further antitumor therapy and a decreased transfusion requirement were seen among responding patients. Those patients with anemia who had evidence of shortened erythrocyte survival and splenic sequestration of 51Cr-labelled erythrocytes uniformly responded with rises in hemoglobin. However, half of the patients with negative splenic sequestration also showed improvement of anemia. Preoperative diagnostic studies failed to predict favorable responses of patients with thrombocytopenia or leukopenia. The classical criteria for the diagnosis of hypersplenism are not applicable in many cases of neoplastic lymphoproliferative disease; splenectomy could have been considered "contraindicated" in most of the patients in this series. We conclude that splenectomy is worth undertaking in patients with lymphoproliferative disease complicated by hematologic depression regardless of marrow findings or the results of other diagnostic studies.
