单中心直肠癌根治性前切除术后局部复发危险因素分析

Risk factors for local recurrence after radical anterior resection of rectal cancer: a single center experience

回顾性分析直肠癌根治性前切除术后局部复发患者23例与按性别、年龄挑选出的未复发患者69例,分析直肠癌根治性前切除术后局部复发危险因素。单因素分析结果显示,肿瘤直径、术后病理阳性淋巴结个数、肿瘤位置高低及T分期是直肠癌根治性前切除术后局部复发的危险因素。Logistic回归分析显示:T分期(T4期)是影响直肠癌根治性前切除术后局部复发的独立因素,肿瘤位置高低(肿瘤距肛缘小于5 cm)则近似构成局部复发的独立危险因素。

Clinical data of 23 locally recurrent rectal cancer patients underwent radical anterior resection and 69 controls matched by age and gender was retrospectively analyzed to find out the risk factors related to local recur- rence after radical anterior resection of rectal carcinoma. Univariate analysis showed that tumor size, number of positive lymph nodes, distance between tumor and the anal verge and T stage were risk factors for locally recurrent rectal cancer after radical anterior resection. The results of logistic regression analysis showed that T stage （T4 stage） was an independent risk factor correlated with the tumor recurrence after radical anterior resection and loca- tion of tumor（ distance of tumor from the anal verge being less than 5 cm） seemed to be an independent risk factor correlated with the tumor recurrence.
