本期中心阐述了有关早期胃癌形态学检查方面的问题。广田映五等作者,从病理形态上分析一组995例早期胃癌,对其形态与分布规纳下列几点:①从年龄和性别来看,高龄者病例增加了(特别70岁以上),男女之比由2:1转为3:1。②病变所居部位(按CMA 分类)。初期在M 区占60%,后期有减少;相反,在A 区有增加,达40%左右。病变在前、后壁均有增加,分别为24%及35%,而在小弯相对减少。③在肉眼形态上,凹陷型由初期的60%增至后
This issue of the center elaborates issues related to the morphological examination of early gastric cancer. Guangtian Yingwu and other authors analyzed a group of 995 cases of early gastric cancer from the pathological aspect. The following points were included in their morphology and distribution: 1 From the perspective of age and gender, the number of elderly patients increased (especially 70 years or older), The ratio of men and women changed from 2:1 to 3:1. 2 The location of the lesion (classified by CMA). In the initial period, it occupied 60% in the M area and decreased in the later period. On the contrary, it increased in area A, reaching about 40%. Lesions increased in both the anterior and posterior walls, 24% and 35%, respectively, and were relatively less in small curves. 3 In the form of the naked eye, the depression type increased from 60% in the initial stage to afterwards
