Kaposi's sarcoma. An update on the results of extended field radiotherapy.

This report reviews the results of extended field radiotherapy (EFR) in the treatment of Kaposi's sarcoma. During the 22-year period that is under study, 54 patients with Kaposi's sarcoma were seen and 38 were treated with EFR. Thirty patients had spontaneous Kaposi's sarcoma and eight had received immunosuppressive therapy. Extended field radiotherapy is compared with both local methods of radiation and chemotherapy in the treatment of Kaposi's sarcoma. It was concluded that EFR is the treatment of choice because of its simplicity, high disease-control rate, and lack of complications in patients without systemic disease manifestations.
