胃癌的诊断与病理特点（附3475例胃镜活检报告）

报道１９８０年１月～１９９１年１２月，因各种上消化道症状而进行胃镜检查的２２４３９例患者，经活检诊断胃恶性肿瘤３４８４例，除９例胃恶性淋巴瘤未列入统计外，计胃癌检出率１５．５％，其中经直视＋活检诊断及术后病理证实的早期胃癌４７例，早期癌检出率为１．３５％。以５０～５９岁组最高（３７．５％），其次为６０～６９岁组（３６．０％），发病部位以胃远心侧为最多（７５．９７％），近心侧胃癌仅占２０．０２％。首次活检阳性率为９４．４％，活检阴性的１９６例中，第二次重检阳性和术后获病理证实的为１２４例，最终活检阳性率为９７．９％，对胃癌病理发病相关原因及如何提高活检诊断率等问题亦进行了探讨。

THE DIAGNOSIS OF GASTRIC CARCINOMA AND ITS PATHOLOGIC FEATURES(A REPORT OF 3 475 CASES OF GASTRIC CARCINOMA WITH BIOPSIED EXAMINATION)

patients with each kind of upper digestive tract symptoms from 1980 to1991 were examined by cndoscopy,in which 3, 475 cascs with gastric carcinoma were detected.9cases with gastric malignant lymphoma were not listcd and the rate of detection was 15.5%. ofthem 47 cases(1.35%)with early gastric carcinoma were proved by biopsics and postoperative pathology.
