目的：分析我院直肠癌根治术后远期效果和影响手术疗效的各种因素。方法：收集我院１９６４年４月～１９８９年１２月根治性切除直肠癌６３８例资料。用生命表法计算生存率，生存曲线用Ｇｅｈａｎ方法作显著性检验。结果：全组手术死亡率０．８％，随访率９８．８％。术后５、１０、１５、２０、２５年生存率为５８．７％、４９．８％、４８．０％、４７．３％和４４．２％。结论：直肠癌术后生存率与年龄、肿瘤部位、大小、侵占肠腔周径、大体和组织学类型、淋巴结转移、病期等有关。其中，淋巴结转移和病期是影响术后生存率的最主要因素。
OBJECTIVE: To analyze the long-term postoperative effects of radical rectal cancer in our hospital and the factors that influence the curative effect. Methods: A total of 638 cases of radical rectal cancer were collected from April 1964 to December 1989 in our hospital. The survival rate was calculated using the life table method, and the survival curve was tested for significance using the Gehan method. Results: The operative mortality rate was 0.8% and the follow-up rate was 98.8%. The survival rates at 5, 10, 15, 20, and 25 years after surgery were 58.7%, 49.8%, 48.0%, 47.3%, and 44.2%. CONCLUSIONS: The survival rate of rectal cancer is related to age, tumor location, size, invasion of intestinal circumference, gross and histological type, lymph node metastasis, and stage of disease. Among them, lymph node metastasis and stage are the most important factors affecting postoperative survival rate.
