Five-year survival rate of the anal cancer on stage classification has been analyzed using Japanese Research Society (J.R.S.) and TNM classification. On studying of 73 consecutive patients who had abdominoperineal resection of the rectum for anal cancer at the Health Insurance Central Hospital, Tokyo, 5-year survival rate of stage II was lower than that of stage III in the J.R.S. while appropriate distribution of survival rate was seen in the TNM classification. On the anal cancer, size or rate of infiltration to circumference of the anal canal of the tumor has an important effect on prognosis. We recommend to add infiltration to circumference of the anal canal as a factor on the stage classification.
使用日本研究学会（J.R.S.）和TNM分类法对肛管癌按分期分类的五年生存率进行了分析。在东京健康保险中央医院，对73例因肛管癌接受腹会阴联合直肠切除术的连续患者进行研究后发现，在J.R.S.分类中，II期的五年生存率低于III期，而在TNM分类中生存率分布合理。对于肛管癌，肿瘤大小或向肛管周径的浸润率对预后有重要影响。我们建议将向肛管周径的浸润作为分期分类的一个因素。
