Utility of Estrogen Receptor, Progesterone Receptor, and HER-2/neu Analysis of Multiple Foci in Multifocal Ipsilateral Invasive Breast Carcinoma.

CONCLUSIONS: Our findings support current recommendations to evaluate additional smaller tumor foci in multifocal invasive breast cancer if the focus is of different grade or histology. Additional features, including specific histology, grade, and ER, PR, and HER2 status of the largest focus, should also be considered when selecting cases for which testing of additional foci may be of benefit.
