  • Title: Splenectomy for palliation of chronic myelocytic leukemia.
    Author: Gomez GA, Sokal JE, Mittelman A, Aungst CW.
    Journal: Am J Med; 1976 Jul; 61(1):14-22. PubMed ID: 59546.
    Abstract:
    Sixty patients with chronic myelocytic leukemia (CML) (most, in the "terminal phase" of the disease) were subjected to splenectomy because of symptomatic splenomegaly, thrombocytopenia or anemia for which they required frequent transfusions. Surgical morbidity and mortality were high when the procedure was performed on a "casual" basis, but both were reduced sharply after care of these patients was restricted to a single medical-surgical-nursing team and improved technics of surgery and perioperative management were developed. Significant hematologic and clinical benefit was achieved in half of the patients and temporary arrest of the disease was often observed, but in most patients, the basic evolution of CML was not greatly altered. In eight patients, however, long-lasting improvement (one to nine years) was recorded. Measurement of the doubling time of circulating leukemic cells and other observations were consistent with the hypothesis that, in some patients, the spleen contains a more rapidly proliferating and "more malignant" population of leukemic cells than the marrow. We conclude that splenectomy is often a useful palliative procedure in advanced stages of CML, and that it may be strikingly beneficial in 10 to 15 per cent of such cases.
