Abstract:
An epidemic of disseminated Kaposi's sarcoma in male homosexuals has recently been described. Forty-one evaluable patients with epidemic Kaposi's sarcoma were treated with etoposide. The majority of these patients had early stage disease, no prior opportunistic infections, and no prior therapy. Twelve patients (30%) achieved complete remission, 19 (46%) partial remission, and ten (24%) no response. With follow-up time to 31 months, the median response duration is nine months. The median survival of patients with complete and partial remissions has not been reached. A combination of doxorubicin (Adriamycin, Adria Laboratories, Columbus, Ohio), bleomycin, and vinblastine (ABV) was used in 31 evaluable patients with epidemic Kaposi's sarcoma. The majority of these patients had late stage disease, prior opportunistic infections, or had failed prior treatment. Seven patients (23%) achieved complete remission, 19 (61%) partial remission, and five (61%) no response. With follow-up time to 24 months, the median response duration is eight months. The projected median survival for all patients treated with ABV is nine months. Both regimens were well tolerated, with an overall response rate of 76% for etoposide and 84% for ABV. However, while successfully treating the Kaposi's sarcoma, the underlying immune deficiency in these patients has persisted. Future treatments of Kaposi's sarcoma will need to focus on reversing the underlying immune incompetence as well as controlling the malignant manifestations of Kaposi's sarcoma arising in relation to the acquired immune deficiency syndrome.
