Jack Cuzick, PhD, on the International Breast Cancer Intervention Study II: 10-Year Results
2019 San Antonio Breast Cancer Symposium
Jack Cuzick, PhD, of Queen Mary University of London, discusses the substantially greater benefits of anastrozole as compared with tamoxifen in terms of preventing breast cancer, with no increase in fractures or other reported serious side effects (Abstract GS4-04).
Gerardo Antonio Umanzor Funez, MD, of Liga Contra El Cáncer, discusses phase III findings on intravenous (IV) paclitaxel and oral paclitaxel plus encequidar (a novel P-gp inhibitor), the first orally administered taxane regimen shown to be superior to the IV formulation in terms of response and survival with less neuropathy (Abstract GS6-01).
Ariella B. Hanker, PhD, of UT Southwestern Medical Center, discusses data showing that breast cancers expressing co-occurring HER2 and HER3 mutations may require the addition of a phosphoinositide 3-kinase alpha inhibitor to a HER2 tyrosine kinase inhibitor (Abstract GS6-04).
Tari A. King, MD, of Brigham and Women’s Hospital and Dana-Farber/ Brigham and Women’s Cancer Center, discusses retrospective findings from the AURORA U.S. Network on molecular differences between primary tumors and metastases, a better understanding of which may help lead to more effective treatment of metastatic breast cancer (Abstract GS3-08).
Javier Cortes, MD, PhD, of the IOB Institute of Oncology, discusses study findings that suggested pembrolizumab offered a prolonged survival benefit compared to chemotherapy for a subset of patients with previously treated metastatic triple-negative breast cancer. In the trial, high tumor-infiltrating lymphocytes were significantly associated with better clinical outcomes with the checkpoint inhibitor.
Joseph Sparano, MD, of the Montefiore Medical Center, discusses three challenges:
- How can gene-expression profiles and other diagnostic tests be used to guide the use of adjuvant systemic therapy?
- Is it time to reappraise active surveillance?
- Are there diagnostic and therapeutic strategies that can identify tumors at highest risk of metastasis, and novel therapies that can block the spread of disease?
