作者根据自己去日本参观学习和日本专家来华交流的内容等,概括地介绍了日本在早期胃癌(以下简称早癌)的研究上所取得的进展。一、较高的早癌检出率据高木氏等列举资料:46～55年手术胃癌为1,313例,早癌28例仅占2.1％;66～75年手术胃癌2,413例,其中早癌竟有678例,占28.1％。30年今昔对比,该院早癌占胃癌手术率之比上升了14倍。日本对胃癌普查发现的例数用发现率表示,而对普查发现的早癌数通常用早癌/切除胃癌之比来计算,即检出率。作为早癌最后确诊是靠切除胃病理诊断.这样计算早癌的检
Based on his visits to Japan and the exchange of Japanese experts in China, the author outlined the progress made in the study of early gastric cancer in Japan. First, a higher rate of detection of early cancer According to Takagi and other listed data: 46 to 55 years of surgery for 1,313 cases of gastric cancer, 28 cases of early cancer accounted for only 2.1%; 66 to 75 years of surgery 2,413 cases of gastric cancer, including early cancer 678 cases, accounting for 28.1%. Comparing the past 30 years, the ratio of early gastric cancer to gastric cancer in the hospital has increased by 14 times. The number of cases discovered by Japan in the general survey of gastric cancer is expressed by the discovery rate, and the number of early cancers found in the census is usually calculated by the ratio of early cancer/resection of gastric cancer, that is, the detection rate. As the final diagnosis of early cancer is based on the pathological diagnosis of resection of the stomach.
