This article describes a total of 10 cases of rectal cancer undergoing preoperative radiotherapy from 1972 to December 1977 in the Altar Hospital. High-energy ray (electron accelerator or ~(60)CO) was used. The range of radiation was from 骶2 to the anal border. Two sides of the pelvic wall, two fields before and after the radiation exposure, tumor volume 3000 ~ 4000rad / 3-4 weeks, after radiotherapy rest rest after 10 days of surgery, 59 cases of abdominal perineal resection, 15 cases of intra-abdominal rectal anastomosis The anus was preserved. In 6 cases, only probing was performed. No surgical difficulties were found during the operation. Compared with the usual single surgery cases, there was no significant difference in bleeding and no increase in complications. In most patients, subjective symptoms improved, tumors shrank in varying degrees, the five-year survival rate was 49.2% (32/65), and the local recurrence rate was 10.7%, which was lower than the 30% reported in the general literature.
