我院从1964年至1979年十五年间收治大肠腺瘤癌变37例,占全部外科治疗的大肠癌的4.2％。本组男18例,女19例。年龄22—68岁,60岁以上占24.3％。从发病至明确诊断的平均病程为22.8个月。本组病变86.5％位于乙状结肠和直肠。按照Dukes分类法,A期11例,B期19例,C期7例。 本组病例的特点为年龄较高、病程较长、肿块大多位于乙状结肠和直肠,而且病期较早。根治性切除的效果很好。当病变局限而且未侵袭肌层,可以作局部切除。 本文还结合文献进行了讨论,并认为大肠腺瘤是大肠癌的癌前病变。
In our hospital, 37 cases of colorectal adenoma were treated from 1964 to 1979, accounting for 4.2% of all surgically treated colorectal cancers. This group of 18 males and 19 females. Ages 22-68 years old, over the age of 60 accounted for 24.3%. The average duration of disease from onset to definitive diagnosis was 22.8 months. 86.5% of lesions in this group were located in the sigmoid colon and rectum. According to the Dukes classification, 11 cases were in stage A, 19 cases in stage B, and 7 cases in stage C. This group of patients is characterized by a higher age, longer duration, masses are mostly located in the sigmoid colon and rectum, and the earlier stage of the disease. Radical resection works well. When the lesion is localized and does not invade the muscular layer, local resection can be performed. This article also discussed with the literature, and that colorectal adenoma is a precancerous lesion of colorectal cancer.
