[Immunohistochemical study of oncogene c-erbb-2 expression and extracellular matrix proteins in breast cancer (various mechanisms of invasion)].
55 breast carcinomas and 9 its benign conditions were studied immunohistochemically. Oncoprotein c-erbB-2 was found in 22% carcinomas and in 33-37% comedo-carcinomas. Coincidence of predominant expression of oncoprotein c-erbB-2 and tenascin was observed. Maximal damage of the basal membrane in the intraductal carcinoma detected by the disturbance of type IV collagen staining was observed in cases of the highest expression of oncoprotein c-erbB-2 and tenascin.
