The addition of pembrolizumab to neoadjuvant chemotherapy followed by adjuvant pembrolizumab plus endocrine therapy improved pathologic complete responses in key subsets of patients with early-stage, high-risk, estrogen receptor–positive/HER2-negative breast cancer enrolled in the phase 3 KEYNOTE-756 trial.
The combination of Keytruda to neoadjuvant chemotherapy, followed by Keytruda in combination with endocrine therapy improved pathologic response rates for patients with early-stage, high-risk, estrogen receptor (ER)–positive/HER2-negative breast cancer.
Joyce A. O’Shaughnessy, MD, highlights multidisciplinary approaches including discussions on tumor boards, and discusses how to better assist patients with accessing care, and notable advances in the field particularly with the HER2 classification.
