胃癌内镜形态与病理类型之间的关联已逐步阐明,依据早期胃癌的形态鉴别其组织分化类型已成为可能。上皮内瘤变作为胃癌的癌前病变,其进展至胃癌的概率不一,但高级别上皮内瘤变与胃癌的关系密切。近年来发布的一系列国际诊断标准初步解决了胃黏膜活检组织的病理学评价这一难题。本文就上述几个方面的研究现状作一概述。
The correlation between endoscopic morphology and pathological type of gastric cancer has been gradually elucidated, and it has become possible to identify the type of tissue differentiation based on the morphology of early gastric cancer. Intraepithelial neoplasia as a precancerous lesion of gastric cancer, the probability of progress to gastric cancer varies, but high-grade intraepithelial neoplasia and gastric cancer are closely related. In recent years, a series of international diagnostic criteria have initially solved the problem of pathological evaluation of gastric mucosal biopsies. This article summarizes the research status of the above aspects.
