The anatomic distribution of carcinoma of the colon and rectum in patients operated upon at this institution over a 30 year period was studied. All patients with recently diagnosed adenocarcinoma of the colon and rectum were placed into one of three groups: right colon, left colon or transverse colon. An analysis of the distribution of tumors over four time periods--1945 to 1949, 1956 to 1957, 1966 to 1969 and 1976 to 1978--revealed an increase in the percentage of tumors of the right colon with time that was most significant in the last time period studied. Various explanations for the recent increased incidence of tumors of the right colon found were discussed.
对在该机构接受手术治疗的患者，在30年期间内结肠和直肠癌的解剖分布进行了研究。所有近期诊断为结肠和直肠癌的腺癌患者被分为三组之一：右半结肠、左半结肠或横结肠。对四个时间段（1945年至1949年、1956年至1957年、1966年至1969年和1976年至1978年）肿瘤分布的分析显示，右半结肠肿瘤的百分比随时间增加，在研究的最后一个时间段最为显著。讨论了对近期发现的右半结肠肿瘤发病率增加的各种解释。
