There are several kinds of proposals for the staging of colon cancer with TNM factors in the world. By comparisons with each survival rates on these staging groups, based on 698 curative resected colon cancer at our hospital between 1962 and 1985, we have evaluated the usefulness of their staging systems. There were no significant differences of survival rates between 3rd and 4th stage groups of J.J.C. classification II and III stage groups of I.C.C. -p-TNM, and Ib and II stage groups of A.J.C. -p-TNM. As far as the resected cases, the degree of spreading of serosal involvement is more affective factor influencing to the prognosis than the one of lymph nodes involvement. Extent of the area of resection and clearance of regional lymph nodes, curative or non curative, is also important prognostic factor. There seems to be still, much room for discussion and revision on the staging of the colon cancer.
目前世界上有几种利用TNM因素对结肠癌进行分期的方案。通过比较这些分期组的各自生存率，基于我院1962年至1985年间698例接受根治性切除的结肠癌病例，我们评估了它们分期系统的实用性。J.J.C.分类的第三和第四阶段组、I.C.C.-p-TNM的第二和第三阶段组以及A.J.C.-p-TNM的Ib和II阶段组之间的生存率没有显著差异。就切除病例而言，浆膜受累的扩散程度比淋巴结受累程度对预后的影响更大。切除范围和区域淋巴结清扫情况，无论是根治性还是非根治性，也是重要的预后因素。结肠癌的分期似乎仍有很大的讨论和修订空间。
