通过对自然人群的3432份胃粘膜病理观察,检出胃癌5例并发现在胃癌高发区人群中,以慢性浅表性胃炎(CSG)检出较为常见,约占总数的67.28％,其次为慢性萎缩性胃炎(CAG),肠上皮化生(IM),分别占总数的3.88％,14.28％。部位检出:CSG体部高于窦部,CAG与IM则窦部明显高于体部(P<0.05)。本报告支持CAG、IM为癌前病变的论点。 Through the pathological observation of 3432 gastric mucosa in the natural population, 5 cases of gastric cancer were detected and found to be chronic common superficial gastritis (CSG) in the population with high incidence of gastric cancer, which accounted for approximately 67.28% of the total, followed by chronic atrophy. Gastritis (CAG) and intestinal metaplasia (IM) accounted for 3.88% and 14.28% of the total. Site detection: CSG body was higher than the sinus, CAG and IM were significantly higher than the body sinus (P <0.05). This report supports the argument that CAG and IM are precancerous lesions.
