有人认为在过去的20年中日本结肠癌发病率显著升高主要是由于饮食习惯的西方化。为了弄清结肠癌分布部位及其相关因素的特点,本文分析了1975年到1994年间的1205例结肠癌病例。 方法:回顾性整理Iizuka医院1975年到1994年间组织学诊断为结肠癌的1205例日本籍患者的资料,分析有关年龄、性别、肿瘤位置等的临床病理资料。肿瘤位置分成三组:近段结肠(盲肠、升结肠、结肠肝曲、横结肠)、远段结肠(结肠脾曲、降结肠、乙状结肠)、直肠。
Some people think that the significant increase in the incidence of colon cancer in Japan in the past 20 years is mainly due to the westernization of eating habits. In order to clarify the characteristics of the distribution of colon cancer and its related factors, this article analyzed 1,205 cases of colon cancer from 1975 to 1994. Methods: The data of 1,205 Japanese patients with histologically diagnosed colon cancer from 1975 to 1994 in Iizuka Hospital were retrospectively reviewed. Clinical and pathological data on age, sex, and tumor location were analyzed. The tumor locations were divided into three groups: proximal colon (cecum, ascending colon, colonic liver and transverse colon), distal colon (colon spleen, descending colon, sigmoid), and rectum.
