日本东京癌研究会附属医院外科,将1946至1975年共30年的胃癌病例,从临床方面对其时代性变化进行了探讨。由于胃诊断方法的迅速进步和普查的广泛开展,早期胃癌被大量发现,这是临床上的最大变化。从来认为不治之症的胃癌,如今也像子宫癌、乳癌那样变为可治之症,此乃胃癌面貌改变的最大特征。作者以早期胃癌为中心,将胃癌的时代性变化分为三个阶段:1946～1955年为第一阶段,1956～1965年为第二阶段,1966～1975年为第三阶段。早期胃癌在胃癌手术案例中的百分比为:第一阶段仅占2.1%,第二阶段为9.7%,第三阶段达28.1%。早期胃癌的肉眼分类,在50～60年代Ⅲ型早期胃癌即开放溃疡
In the Department of Surgery, Affiliated Hospital of Tokyo Cancer Research Society, Japan, a 30-year history of gastric cancer from 1946 to 1975 was examined in terms of clinical changes. Due to the rapid advancement of gastric diagnostic methods and the widespread implementation of census, early gastric cancer has been discovered in large numbers, which is the biggest change in clinical practice. It has been thought that incurable stomach cancer is now becoming treatable as uterine cancer and breast cancer. This is the biggest feature of changes in the appearance of gastric cancer. The author focuses on early gastric cancer and divides the era of gastric cancer into three phases: the first phase from 1946 to 1955, the second phase from 1956 to 1965, and the third phase from 1966 to 1975. The percentage of early-stage gastric cancer in gastric cancer surgery cases was: 2.1% in the first phase, 9.7% in the second phase, and 28.1% in the third phase. The naked eye classification of early gastric cancer, type III early gastric cancer in the 50 ~ 60 years that is open ulcer
