Abstract
The lesions of mycosis fungoides are radiosensitive and because extensive areas of the body are usually involved, the treatment of choice is with the electron beam. Since 1971, a fractionation scheme of weekly doses for irradiation of the entire skin surface has been practiced with a 6 MeV linear accelerator that generates 3.5 MeV electrons. One hundred and five patients were treated in this way by delivering 400 rads once weekly for six consecutive weeks. All patients enjoyed complete disappearance of the skin lesions at once. Of the 62 patients whom we were able to follow‐up after electron‐beam therapy, for periods ranging from one to nearly seven years (median, two years), the duration of remission was one‐half to nearly five and a half years (median, one and one‐half years). The treatment was well tolerated and no unusual skin reactions or hematopoietic depression occurred.
