We have investigated whether the incidence of early gastric cancer continues to increase. During the last 16 years, from January 1, 1974, through December 31, 1989, 842 patients with primary carcinoma of the stomach were admitted. Of these 842, 676 (80%) underwent gastric resections. During the first 8 years of this study, 391 patients were admitted, and during the second 8 years, 451 patients were admitted. Early cancer in the first 8 years accounted for 28% of the resected cases and 22% of the total cases of gastric cancer. In the second 8 years, early gastric cancer accounted for 38% of the resected cases and 32% of the total number of cases of gastric cancer. The number of early gastric cancers as a proportion of resected cases increased significantly in the second 8 years. Approximately 50% of early gastric cancers were detected as a result of routine upper gastrointestinal examinations which were performed on patients with no clinical features suggestive of a malignant underlying process. We emphasize that gastroenterologists are unlikely to witness a significant increase in the rate of detection of gastric cancer in the early stage as long as both double-contrast radiographic techniques and endoscopic biopsies are performed predominantly only on patients with symptoms that are apparently suggestive of gastric malignancies.
我们调查了早期胃癌的发病率是否持续上升。在1974年1月1日至1989年12月31日的过去16年中，收治了842例原发性胃癌患者。其中676例（80%）接受了胃切除术。在本研究的前8年，收治了391例患者，后8年收治了451例患者。前8年的早期癌症占切除病例的28%，占胃癌总病例的22%。在后8年，早期胃癌占切除病例的38%，占胃癌病例总数的32%。后8年中，早期胃癌占切除病例的比例显著增加。约50%的早期胃癌是在对无恶性潜在病变临床特征的患者进行常规上消化道检查时发现的。我们强调，只要双重对比造影技术和内镜活检主要仅针对有明显提示胃恶性肿瘤症状的患者进行，胃肠病学家不太可能看到早期胃癌检出率的显著增加。
