摘要 目的 分析影响老年直肠癌患者术后生存时间的风险因素.方法 回顾性分析影响直肠癌术后2年内复发的相关影响因素,包括年龄、性别、肿瘤位置、肿瘤大小、手术方式、临床分期、术前癌胚抗原(CEA)水平、肿瘤病理分型、肿瘤大体分型以及是否并发肠梗阻等.结果 术后2年的生存率溃疡型患者显著低于隆起型患者(x2=4.500,P=0.034);低分化腺癌型患者术后显著低于高中型分化腺癌患者(x2=13.460,P=0.001);临床分期为Ⅳ的患者显著低于其他分期的患者(x2=20.590,P=0.00l);术前CEA >5 ng/m的患者显著低于术前CEA≤5 ng/m患者(x2=7.384,P=0.007);术前癌抗原(CA)-199 >40 ng/m的患者显著低于术前CA-199≤40 ng/m患者(x2 =9.517,P=0.002).Cox多元回归分析显示大体分型为溃疡型、临床分期晚(Ⅲ~Ⅳ)、术前CEA>5 ng/ml及病理分型为低分化腺癌是导致直肠癌术后2年生存率低的独立影响因素.结论 针对影响老年直肠癌患者术后生存时间的风险因素及早干预,有望延长术后生存时间.
