title: Immunohistochemical distribution of c-erbB-2 in infiltrating and in situ breast cancer.
abstract: An immunohistochemical study of c-erbB-2 expression was performed on invasive and in situ breast cancer. Strong membrane staining was seen in 16% of the infiltrating ductal carcinomas and 44% of the in situ lesions. c-erbB-2 was overexpressed in ductal rather than lobular tumours. Our results indicate that a small sub-group of breast carcinomas are associated with over-expression of this oncogene which may define an important subgroup of in situ and infiltrating ductal carcinomas.
