将93例胃癌和4例异型增生标本固定后用水冲去粘液,爱新兰和苏木素分别染色。胃粘膜表面的胃小区、小凹等细微结构呈现出特有的粘膜纹,易于辩认。早期癌(特别是微小癌),异型增生,肠上皮化生等病变的色彩形态出现各自特征。淡染或不着色,粘膜纹“融解消失”、“虫食”、“断裂”等为癌的特征,使微小癌检出率达70.6%。 93 cases of gastric cancer and 4 cases of atypical hyperplasia were fixed and washed with water to remove mucus. Ailan and hematoxylin were stained separately. The fine structure of the stomach area, pits, etc. on the surface of the gastric mucosa exhibits a characteristic mucosal pattern, which is easy to recognize. The color features of early stage cancers (especially microcancerous), dysplasia, and metaplasia of the intestine appear to have their own characteristics. Lightly stained or non-stained, mucosal features such as “melting and disappearing”, “insectivorous”, and “rupture” are features of cancer, and the detection rate of micro-cancer is 70.6%.
