In 1979, there were 24 cases of rectal and rectal anal canal cancer for preoperative radiation therapy. Case materials: All patients were confirmed by biopsy prior to treatment, and were determined by two doctors in the collaborative group.

Three cases of rectal anal canal cancer were treated with the perineal field, and the rest of the abdomen was removed from the abdomen. According to the size of the wild, depending on the size of the lesion, the length and width are each 10 to 15 cm, and the tumor dose of 4000 to 5000 pulls 18/24. Mostly in radiotherapy
