Overexpression of erbB-2 versus chemotherapy response

Overexpression of erbB-2, as determined by immunohistochemistry, was not significantly associated with breast tumor response to chemotherapy (P = 0.114), although if CR or MRD versus all of the other responses are compared, there was a borderline association (P = 0.051). Response was determined by comparison of the breast tumor at presentation with the mastectomy specimen.
