在胃癌高发区有代表性群体中全面观察胃粘膜病变的特点,特别是癌前病变与胃癌的关系对于阐明癌变机理、流行因素以及对癌变的干予研究都具有重要意义。自1985年,我们在山东省临朐县胃癌高发区对一组30～64岁随机人群进行了胃镜和病理学检查,分析了胃粘膜病变在不同年龄组,胃不同部位的特点以及与胃癌的关系。现将初步分析结果报告如下。
The comprehensive observation of gastric mucosal lesions in a representative population of high-incidence areas of gastric cancer, especially the relationship between precancerous lesions and gastric cancer, is of great significance in elucidating the mechanism of canceration, epidemiological factors, and the study of carcinogenesis. Since 1985, we conducted a gastroscopy and pathological examination of a group of 30 to 64-year-old randomized population in the high incidence area of gastric cancer in Linyi County, Shandong Province. We analyzed the characteristics of gastric mucosal lesions in different age groups, different parts of the stomach, and the relationship with gastric cancer. . The preliminary analysis results are reported below.
