Initial observations of the effect of radiotherapy on epidemic Kaposi's sarcoma.

Fifteen patients who had Kaposi's sarcoma in conjunction with the acquired immune deficiency syndrome (AIDS) received radiotherapy to a total of 17 selected lesions. All tumors exhibited at least partial regression, and the majority responded completely. The radiosensitivity of these lesions is similar to that observed in the classic form of the disease. We conclude that in appropriately selected cases radiotherapy should be considered the treatment of choice.
