Abstract: |
Kaposi's sarcoma occurs in about one third of patients with the acquired immunodeficiency syndrome. Although in some patients the tumor is principally a cosmetic problem, other patients have progressive disease with significant morbidity. Twenty-three patients with Kaposi's sarcoma related to the acquired immunodeficiency syndrome were treated with vincristine. Three patients had a coexisting immune thrombocytopenia. Of the 18 patients evaluable for response, 11 had a partial response and 7 had a minor response. The median duration of partial response was 4+months. All 3 thrombocytopenic patients developed a significant increase in platelet count, which in 2 was sustained with continued treatment for 6 and 9 months, respectively. We conclude that vincristine has antitumor activity in the epidemic form of Kaposi's sarcoma and that it is also effective in the treatment of associated immune thrombocytopenia. |
