本文对１９８８年６月至１９９５年６月经纤维结肠镜结合病理组织学确诊为大肠癌３００例进行分析。其中男性１７５例，女性１２５例，男女之比为１．４：１。年龄中位数为４８．５岁。进展期大肠癌２９５例，早期大肠癌５例。病理组织学确诊为腺癌占７３％，解剖部位以直肠最多，乙状结肠次之。大肠癌随其癌灶大小、癌肿发生部位及病理类型的不同，其临床表现也不同，常延误诊断或漏诊，应引起临床医师重视。
In this paper, 300 cases of colorectal cancer were diagnosed by colonoscopy combined with histopathology from June 1988 to June 1995. There were 175 males and 125 females, with a male to female ratio of 1.4:1. The median age was 48.5 years. There were 295 cases of advanced colorectal cancer and 5 cases of early colorectal cancer. Histopathology diagnosed as adenocarcinoma accounted for 73% of the anatomical site with the most rectum, followed by sigmoid colon. The colorectal cancer has different clinical manifestations depending on the size of the cancer foci, the location of the cancerous lesions, and the pathological types. It often leads to delays in diagnosis or missed diagnosis, and should be taken seriously by clinicians.
