Prognostic value of c‐erbB2 expression in breast cancer

Abstract

The c-erbB2 expression is an independent significant factor for breast cancer and the prognostic significance remains in the node negative as well as node positive breast cancer, while the same effect was also found in all subgroups stratified according to the adjuvant therapies. In addition, the combination of c-erbB2 and ER made it possible to identify the subgroup with the worst clinical outcome.
