对800例慢性浅表性胃炎患者进行活组织学追踪观察,并经术后病理检查证实Ⅱb型早期胃癌占1.3%(12/800例)。结果表明从患慢性浅表性胃炎1年左右者检出癌4例(1.1%),背景为正常胃粘膜并癌变,慢性浅表性胃炎属伴发。患病16年左右者检出癌3例(1.4%),背景病变为慢性浅表性胃炎,直接癌变。24年左右者检出5例(2.5%),背景病变为慢性萎缩性胃炎,其由慢性浅表性胃炎演变而来,经肠上皮型异型腺管癌变。
800 patients with chronic superficial gastritis were observed by biopsy and postoperative pathological examination confirmed that type IIb early gastric cancer accounted for 1.3% (12/800 cases). The results showed that 4 cases (1.1%) of cancer were detected in patients with chronic superficial gastritis for 1 year. The background was normal gastric mucosa and cancerous, and chronic superficial gastritis was associated. About 16 years of illness, 3 cases (1.4%) of cancers were detected, and the background lesions were chronic superficial gastritis and direct canceration. Around the age of 24 years, 5 cases (2.5%) were detected, and the background lesions were chronic atrophic gastritis, which evolved from chronic superficial gastritis and was diagnosed as intestinal epithelial type heterogeneous ducts.
