低位Duck A期直肠癌手术方式与局部复发及预后的关系分析

目的 探讨低位Duck A期直肠癌行保肛手术和腹会阴联合根治术（Miles手术）对局部复发率和生存率的影响。方法 回顾性分析72例低位Duck A期直肠癌的临床资料。结果 30例行Miles手术，42例行保肛手术；局部复发率为6．94％，其中腹会阴联合根治术组为6．67％，保肛术组为7．14％；3年总生存率为95．8％，其中Miles手术组为96．7％，保肛手术组为95．2％。两种手术方式的局部复发率和3年总生存率差异均无统计学意义（均P〉0．05）。结论 低位Duck A期直肠癌保肛手术和Miles手术对局部复发率和3年生存率无明显影响。

Correlation of surgical manner with local relapse and prognosis in lower rectal cancer of Duck stage A

Objective To compare the local relapse and the survival rate within 3 years between patients with lower rectal cancer of Duck stage A after sphincter-preserving surgery and Miles surgery.Methods The clinicopathologic factors of 72 patients with lower rectal carcinoma of Duck stage A were retrospectively analyzed.Results Including operineal resection for rectal cancer in 30 cases and sphincter-preserving surgery in 42 cases.The local relapse rate was 6.94%,and it was 6.67% and 7.14% in the patients received operineal resection for rectal cancer and sphincter-preserving surgery respectively.The total survival rate within 3 years was 95.8%,and it was 96.7% and 95.2% in the patients received Miles surgery and sphincter-preserving surgery respectively.The results of chi-square test showed that the local relapse rate and the survival rate within 3 years were not significantly different between patients with lower rectal cancer of Duck stage A after sphincter-preserving surgery and Miles surgery(P>0.05).Conclusion The local relapse rate and the survival rate within 3 years has no significant difference between patients with lower rectal cancer of Duck stage A after sphincter-preserving surgery and Miles surgery.
