Nomogram to predict pathologic complete response in HER2-positive breast cancer treated with neoadjuvant systemic therapy

摘要

Background: Pathologic complete response (pCR) is associated with improved survival outcomes in patients with HER2-positive primary breast cancer. We developed a nomogram to predict the probability of pCR rates by using oestrogen receptor (ER) expression, progesterone receptor (PR) expression and HER2/CEP17 ratio as continuous variables.
