目的：探讨直肠癌术后复发原因与预防。方法对我科2006年10月~2010年5月收治的136例术后复发直肠癌的临床资料进行回顾性分析。结果直肠癌发病高峰年龄为50~70岁，占64.8%，中分化腺癌占42.9%，Ⅰ、Ⅱ期病例占58.1%，Ⅲ、Ⅳ期病例占41.9%，1年内转移占48.5%，多部位转移占62.9%，单部位转移占37.1%。结论术中增加淋巴结清扫数目，可提高分期的准确性，指导拟定合理的术后治疗方案，改善患者预后。局部晚期直肠癌，术前新辅助放化疗可减少术后局部复发率。

Objective:We aimed to study the reasons and prevention of postoperative recurrence of rectal cancer. Methods:A clinical retrospective analysis is operated on 136 cases of postoperative rectal cancer recurrence between 2006.10 to 2010 05. Results:The peak age interval of rectal cancer is 50-70 years,occupied 64.8%, mid-dif erentiation adenocarcinoma occupied 42.9%, cases of stagingⅠandⅡoccupied 58.1%,cases of stagingⅢandⅣoccupied 41.9%,metastasis within 1 year occupied 48.5%,multiple-sites metastasis occupied 62.9%, mono-site metastasis occupied 37.1%. Conclusion:Increasing the number of lymph node dissection in operation improves accuracy of staging and guidance to develop a reasonable amount of postoperative treatment programmers, improving patient outcomes.Preoperative neoadjuvant chemotherapies contribute to lower postoperative local recurrence rate for local y advanced rectal cancer cases.
