A randomized study comparing two high-dose per fraction radiation schedules in recurrent or metastatic malignant melanoma.

Thirty-five tumors in 14 patients with metastatic or recurrent malignant melanoma were randomized to high dose per fraction radiotherapy at either 9 Gy X 3 or 5 Gy X 8 twice weekly. Complete and persistent regression was found in 24/35 (69%) and partial response in 10/35 of the tumors. The overall response rate was 97%. No difference was observed between the two treatment regimens. Acute and late radiation damage to normal tissue was acceptable and of the same magnitude in both schedules.
