Ivana Sestak, PhD, on Clinical Treatment Score From TAILORx: Predicting Distant Breast Cancer Recurrence
2019 San Antonio Breast Cancer Symposium
Ivana Sestak, PhD, of Queen Mary University of London and the Centre for Cancer Prevention, discusses study findings that confirm the prognostic ability of the Clinical Treatment Score at 5 years (CTS5) for late distant recurrence, specifically for patients older than 50 years and/or for those deemed to have intermediate- or high-risk hormone receptor–positive, HER2-negative, node-negative breast cancer. The CTS5 is less prognostic in women younger than 50 who received 5 years of endocrine therapy alone (Abstract GS4-03).
Marie-Jeanne T.F.D. Vrancken Peeters, MD, PhD, of the Netherlands Cancer Institute, discusses an interim study analysis showing that ultrasound-guided core biopsies of the breast in patients with excellent response on MRI after neoadjuvant systemic therapy may not be accurate enough to safely select patients with pathologic complete response for omission of surgery (Abstract GS5-06).
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses trial data on margetuximab plus chemotherapy, which improved progression-free survival in patients with previously treated HER2-positive metastatic breast cancer when compared with trastuzumab plus chemotherapy. Maturing data comparing overall survival also provides new insights (Abstract GS1-02).
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).
Belinda Kingston, MB ChB, of the Institute of Cancer Research London, discusses next-generation sequencing results from the plasmaMATCH trial, including the incidence of gene alterations overall, as well as the associations with clinical and pathologic features that may help direct treatment decisions (Abstract GS3-07).
Ian E. Krop, MD, PhD, of Dana-Farber Cancer Institute, discusses phase II trial findings on trastuzumab deruxtecan, a HER2-targeting antibody-drug conjugate, in patients with HER2-positive metastatic breast cancer who were previously treated with trastuzumab emtansine (Abstract GS1-03).
