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。
Reported from January 1980 to December 1991, 22439 patients underwent gastroscopy due to various upper gastrointestinal symptoms. 3484 cases of gastric cancer were diagnosed by biopsy, except that 9 cases of gastric malignant lymphoma were excluded from the statistics. The detection rate of gastric cancer was 15.5%, including 47 cases of early gastric cancer confirmed by direct vision + biopsy and postoperative pathology. The early cancer detection rate was 1.35%. It was highest in the 50-59 years old group (37.5%), followed by the 60-69 year old group (36.0%). The farest part of the diseased area was the far-side of the stomach (75.97%), and only proximal gastric cancer was accounted for. 20.02%. The positive rate of the first biopsy was 94.4%. Among the 196 cases with negative biopsy, the second one was positive and the pathologically confirmed was 124. The final biopsy positive rate was 97.9%. And how to improve the biopsy diagnostic rate and other issues are also discussed.
