【摘要】 背景与目的:中国结直肠癌发病率逐年上升,其中直肠癌所占比例超过50%,尤以中低位直肠癌多见。男性患者由于盆腔的解剖特点,在治疗方式的选择、保肛比例及预后方面均有其自身的特点。本研究旨在探讨男性直肠癌患者临床病理特征及其与预后的关系。方法:选择年龄、病程、首发症状、肿瘤部位、肿瘤大小、肿瘤占肠腔周径比例、肿瘤大体类型、组织类型、肠壁浸润深度、Dukes@分期、淋巴结转移位置及术式等12项临床病理指标,用单因素和多因素分析的方法研究其对384例男性直肠癌患者预后的影响。结果:单因素分析显示,肿瘤部位、肿瘤大体类型、组织类型、肿瘤浸润肠壁深度、淋巴结转移位置及Dukes@分期为影响预后的因素。Cox比例危险回归模型多因素分析显示,仅组织类型及淋巴结转移位置为男性直肠癌患者预后的独立影响因素。结论:组织类型及淋巴结转移位置为男性直肠癌预后的独立影响因素。更多还原

【Abstract】 BACKGROUND & OBJECTIVE: The incidence of colorectal cancer is increasing in China, of which rectal cancer accounts for over 50%. Because of the limitation of pelvic cavity, the selection of surgical procedures, the proportion of sphincter saving and prognosis of male patients are different from those of female patients. This study was to analyze the correlations of clinicopathologic features of rectal cancer in 384 male patients to their prognosis. METHODS: Correlations of 12 clinicopathologic factors of 384 male patients with rectal cancer to the prognosis were studied with univariate and multivariate analysis. RESULTS: Univariate analysis revealed that tumor site, gross type, histologic type, infiltrative extent to bowel wall, site of lymphatic metastasis and Dukes’ stage were prognostic factors of male patients with rectal cancer. Multivariate analysis revealed that histologic type and site of lymphatic metastasis were independent prognostic factors. CONCLUSION: Histologic type and site of lymphatic metastasis are independent prognostic factors of male patients with rectal cancer.更多还原
