首届全国大肠癌学术研讨会于1987年10月13日至16日在北京举行。现将有关资料综合如下。流行病学近年来的资料表明,在胃癌、食管癌发病率下降的同时,大肠癌的发病率呈上升趋势。据莫善兢报道1981～1983年中,上海市区共有大肠癌患者3665人,比1972～1974年增加48.1％。大肠癌从70年代初的第六位上升到80年代初的第四位。预测到2 000年,发病率将由80年代初的20.67/10万增加到46.68/10万,成为第三位恶性肿瘤。其防治问题日益受到学者们的重视。病因学郑树、焦登鳌等报道大肠癌的发病与能量供耗平衡、饮食及环境有关。环境因素重于遗传因素。在环境因素中以食物、
The first National Symposium on Colorectal Cancer was held in Beijing from October 13 to October 1987. The relevant information is now summarized as follows. Recent data from epidemiology show that while the incidence of gastric cancer and esophageal cancer is decreasing, the incidence of colorectal cancer is on the rise. According to Mo Shanyin, from 1981 to 1983, there were 3,665 patients with colorectal cancer in Shanghai, an increase of 48.1% from 1972 to 1974. Colorectal cancer rose from the sixth in the early 1970s to the fourth in the early 80s. It is predicted that by the year 2000, the incidence will increase from 20.67 per 100 000 in the early 1980s to 46.68 per 100 000, becoming the third malignancy. The issue of prevention and control has been increasingly valued by scholars. Etiology Zheng Shu, Jiao Dengyu et al reported that the onset of colorectal cancer is related to energy balance, diet and environment. Environmental factors are more important than genetic factors. In the environment, food,
