Treatment of Kaposi's Sarcoma in Acquired Immunodeficiency Syndrome with an Alternating Vincristine-vinblastine Regimen

Twenty-four patients with acquired immunodeficiency syndrome and Kaposi's sarcoma (KS) were treated with a regimen alternating vincristine with vinblastine on a weekly basis. Objective responses to this regimen were observed in nine patients (45%), and seven (35%) had stabilization of progressive KS. Few toxic effects were observed. Alternating vincristine-vinblastine therapy is well-tolerated and effective palliative treatment for KS in acquired immunodeficiency syndrome.
