目的评价放疗对晚期直肠癌术后病人的作用。方法从１９９０年１月～１９９３年１２月，我科共收治晚期直肠癌术后放疗病人３２例，年龄最小２８岁，最大６５岁，中位年龄４５岁。所有病例均经病理证实，腺癌３１例，腺鳞癌１例。放疗剂量为４０～５５ＧＹ／４～６周。结果术后与放疗间隔时间１～３个月１５例，复发率２６．７％，３～５个月１７例，复发率４３．７％（Ｐ＜０．０５）。１、３年生存率分别为９０．３％、１９．４％。结论晚期直肠癌术后放疗时间越早越好，并可减少复发率。
Objective To evaluate the effect of radiotherapy on postoperative patients with advanced rectal cancer. Methods From January 1990 to December 1993, 32 patients with postoperative radiotherapy for advanced rectal cancer were treated in our department. The youngest patients were 28 years old and 65 years old. The median age was 45 years. All cases were confirmed by pathology. There were 31 cases of adenocarcinoma and 1 case of adenosquamous carcinoma. Radiotherapy dose is 40 ~ 55GY / 4 ~ 6 weeks. Results Fifteen patients were followed up for 1 to 3 months after radiotherapy. The recurrence rate was 26.7%, and 3 to 5 months in 17 cases. The recurrence rate was 43.7% (P<0.05). The 1-year and 3-year survival rates were 90.3% and 19.4%, respectively. Conclusions The early postoperative radiotherapy for advanced rectal cancer is better, and the recurrence rate can be reduced.
