大肠癌是一种比较常见的恶性肿瘤,其发病率在我国西南地区稍低于胃癌。我院从1970年到1980年6月收治的病例统计,胃癌为276例,大肠癌为264例。 大肠腺瘤,特别是乳头状腺瘤,与大肠癌的发生发展有密切关系,已被公认。有人对家族性多发性腺瘤随访20年,认为如不治疗均可癌变。有人认为大肠癌均由腺瘤演变而来T,而不同意大肠癌是由大肠腺窝上及细胞直接一步癌变(de NOVO)。但也有持反对意见的。为了观察腺瘤的癌变过程,对136例大肠腺瘤进行病理学观察分析。
Colorectal cancer is a relatively common malignant tumor, and its incidence is slightly lower than gastric cancer in southwest China. Statistics from our hospital from 1970 to June 1980 included 276 cases of gastric cancer and 264 cases of colorectal cancer. Colorectal adenomas, especially papillary adenomas, are closely related to the development of colorectal cancer and have been recognized. Some people have followed up for 20 years with familial multiple adenomas and think that cancer can occur if they are not treated. Some people think that colorectal cancer evolved from adenoma T, but do not agree that colorectal cancer is a step-by-step cancerous change (de NOVO). However, there are also objections. In order to observe the carcinogenesis of adenomas, 136 cases of colorectal adenomas were analyzed by pathology.
