对60例早期胃癌及场周病变进行病理形态学观察并与粘膜活检结果对照,其中27例进行粘液组化染色.结果表明:早期胃癌多为浅表凹陷性溃疡或糜烂,粘膜内癌以印戒细胞癌多见,粘膜下癌可有淋巴管内癌栓或淋巴结转移,癌周伴有不同程度的萎缩性胃炎、肠上皮化生及异型增生.粘液组化染色显示癌灶以混合型及肠型为主,癌周肠化上皮以大肠型为主.胃镜及粘膜活检对早期胃癌的诊断起重要作用.
Sixty cases of early gastric cancer and pathological lesions were observed and compared with mucosal biopsy results. Among them, 27 cases were stained with mucinous histochemistry. The results showed that most of the early gastric cancers were superficial depressed ulcers or erosions, and the intramucosal cancer was in India. Predominantly ring cell cancers, submucosal cancers may have lymphatic metastasis or lymph node metastasis, with varying degrees of atrophic gastritis, intestinal metaplasia, and dysplasia. Mucin histochemical staining shows mixed foci and intestinal The type is predominant, and the intestinal metastatic epithelium is mainly of large intestine type. Gastroscopy and mucosal biopsy play an important role in the diagnosis of early gastric cancer.
