Key Points

Key Points

  • Multiple studies of both chemotherapy and endocrine therapy have shown that neoadjuvant treatment can increase the likelihood of breast-conserving surgery.
  • The CTNeoBC pooled analysis of neoadjuvant breast cancer clinical trials published in 2014 confirmed that achievement of a pathologic complete response (pCR) with neoadjuvant treatment was prognostic.
    • It also showed that the association between pCR and outcomes was strongest in patients with triple negative and human epidermal growth factor receptor 2 (HER2)-positive disease.
  • Optimal therapy for breast cancer is driven by subtype.
