Breast Cancer Update for Surgeons, Issue 1, 2019 — Part #2: Our interview with Dr King highlights the following topics as well as cases from her practice:

  • Recent developments in the surgical care of patients with breast cancer (00:0s
  • Predictive versus prognostic role of the 21-gene assay RS in ER-positive, HER2-negative, node-positive breast cancer (01:45)
  • Clinical implications of the TAILORx trial results (05:11)
  • Reliability of the 21-gene assay RS in guiding neoadjuvant therapy decision-making (07:19)
  • Impact of genomic assay testing and clinical features on the use of chemotherapy after the implementation of standardized reflex testing criteria  (10:39)
  • Clinical utility of the 21-gene assay RS in the selection of therapy  (15:34)
  • Application and utility of the MINDACT trial results; use of the 70-gene signature assay in breast cancer  (17:48)
