Quantitative HER2 and p95HER2 levels in primary breast cancers and matched brain metastases

Abstract

This is the first study of quantitative p95 and HER2 expression in matched PBC and BM. BM of breast cancer shows significant increases in expression of both biomarkers compared with matched PBC. These data provide a rationale for future correlative studies on p95 and HER2 levels in BM.
