Priya Rastogi, MD, of the University of Pittsburgh, discusses results from the NRG Oncology/NSABP B-42 trial, which evaluated the utility of the 70-gene MammaPrint assay in predicting the benefit of extended letrozole therapy in patients who had completed 5 years of adjuvant endocrine therapy (Abstract 502).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses first phase III results from a prospective high-risk cohort of patients with luminal breast cancer, which showed a good prognosis in some women with more than four positive lymph nodes and low recurrence scores. The study also showed that a lower postendocrine Ki67 index and limited tumor burden may be promising criteria for chemotherapy de-escalation strategies, even in patients with high recurrence scores (Abstract 504).
Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses phase III results from KEYNOTE-564, which evaluated the safety and efficacy of pembrolizumab in the adjuvant treatment of patients with renal cell carcinoma who have undergone nephrectomy for intermediate-high or high-risk disease or no evidence of disease (Abstract LBA5).
Sumanta K. Pal, MD, of City of Hope, discusses results from a phase II study that sought to determine whether adding berzosertib, a selective ATR inhibitor, to the standard upfront chemotherapy regimen of cisplatin with gemcitabine may improve outcomes in patients with metastatic urothelial carcinoma (Abstract 4507).
Terry P. Mamounas, MD, MPH, of the University of Florida Health Cancer Center, discusses results from the NRG Oncology/NSABP B-42 study, which examined the Breast Cancer Index and its ability to predict whether extended treatment with letrozole benefits patients with hormone receptor–positive breast cancer (Abstract 501).
Nicholas J. Short, MD, of The University of Texas MD Anderson Cancer Center, discusses early results from a phase II study which showed that combining ponatinib and blinatumomab in patients with Philadelphia chromosome–positive acute lymphoblastic leukemia may prove to be an effective chemotherapy-free regimen that might reduce the need for allogeneic hematopoietic stem cell transplant (Abstract 7001).
