Debra A. Pratt, MD, on Time to Completion of Breast Cancer Treatment and Survival
2020 San Antonio Breast Cancer Symposium
In her recent study, Debra A. Pratt, MD, of the Cleveland Clinic, showed that when breast cancer treatment using any of three modalities takes longer than 38 weeks, it is associated with a decrease in survival, regardless of the receptor status. Patients with breast cancer who received neoadjuvant chemotherapy were more likely to take longer than 38 weeks to complete treatment than those undergoing surgery first (Abstract S11-34 ).
Elizabeth A. Mittendorf, MD, PhD, of Brigham and Women’s Hospital, summarizes her plenary talk, which featured the uncertainties in treatment knowledge: excision of postchemotherapy calcifications; the best sentinel lymph node biopsy technique for patients with node-positive disease who convert to node-negative disease with neoadjuvant chemotherapy; whether immunohistochemistry should be routinely used for sentinel lymph node evaluation; and the role of radiation therapy in this patient population.
Lee S. Schwartzberg, MD, of the West Cancer Center, discusses phase III results from the CONTESSA study, which showed that an all-oral regimen of tesetaxel plus a reduced dose of capecitabine significantly improved progression-free survival compared with capecitabine alone in patients with HER2-negative, hormone receptor–positive metastatic breast cancer previously treated with a taxane (Abstract GS4-01).
Editor's note: On March 22, 2021, Odonate Therapeutics announced it was discontinuing the development of tesetaxel and will close the company's operations. Read more here.
Joyce V. Lee, PhD, of the University of California, San Francisco, discusses data that suggest the MYC oncogene may indicate whether a patient with triple-negative breast cancer will respond to immunotherapy. Dr. Lee’s study is the first to describe MYC downregulation of MHC-I and to demonstrate translatable approaches that may overcome immune evasion (Abstract GS1-08).
Patricia A. Ganz, MD, of the University of California, Los Angeles, discusses study findings that showed mindfulness meditation and survivorship education may effectively reduce depression and related symptoms such as fatigue and sleep disturbance, which pose serious threats to younger women’s health and well-being after being treated for cancer (Abstract GS2-10).
Nadia Harbeck, MD, of the University of Munich, discusses the first outcome data from the phase III ADAPT HR+/HER– trial, which combined both static and dynamic biomarkers to optimize the adjuvant therapy approach in patients with intermediate- or high-risk luminal early breast cancer (Abstract GS4-04).
