Patricia A. Ganz, MD, on Breast Cancer: Whole- vs Partial-Breast Irradiation
2019 ASCO Annual Meeting
Patricia A. Ganz, MD, of NRG Oncology and Jonsson Comprehensive Cancer Center at UCLA, discusses the NRG/NSABP phase III findings, which showed that partial-breast irradiation was more convenient and resulted in less fatigue but slightly poorer cosmesis at 36 months in patients who did not receive chemotherapy (Abstract 508).
Hani M. Babiker, MD, of the The University of Arizona, discusses an emerging treatment that inhibits the mitotic spindle and disrupts tumor cell growth. The method has been approved by the FDA to treat some cancers and data show improved progression-free and overall survival (Abstracts 2055, 8551, e14658, e14668, e15653, e20069, e15766).
Miriam Knoll, MD, and Zachery Reichert, MD, PhD, discuss the FORCE trial, which is examining whether radiation can create a more durable response to systemic therapy, and whether using newer, more sensitive imaging technologies can improve outcomes (Abstract TPS5096).
Don S. Dizon, MD, of the Lifespan Cancer Institute, and Richard T. Penson, MD, of Massachusetts General Hospital Cancer Center, discuss phase III study findings on the PARP inhibitor olaparib, which showed a significantly higher objective response rate vs nonplatinum chemotherapy for patients with ovarian cancer who relapsed, are platinum-sensitive, and have BRCA-mutant disease (Abstract 5506).
William D. Tap, MD, of Memorial Sloan Kettering Cancer Center, discusses negative study findings on doxorubicin plus olaratumab vs doxorubicin plus placebo, which showed no difference in overall survival between the two treatments in patients with advanced soft-tissue sarcomas. The manufacturer is currently withdrawing olaratumab from the global market (Abstract LBA3).
William G. Wierda, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses the TRANSCEND CLL 004 trial, which studied the use of an experimental CD19-directed CAR T-cell product in heavily pretreated patients with chronic lymphocytic leukemia or small lymphocytic lymphoma (Abstract 7501).
