The role of human epidermal growth factor receptor 2 in the survival of women with estrogen and progesterone receptor‐negative, invasive breast cancer: The California Cancer Registry, 1999–2004

Abstract

Patients with TN tumors shared many clinical, demographic, and tumor features and had survival that was very similar survival to that of patients with DN tumors, and survival for both groups contrasted greatly with survival for patients with OBC. Disease stage, tumor grade, SES, race/ethnicity, negative ER and PR status, rather than negative HER2 status, were risk factors for survival.
