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).
Matt D. Galsky, MD, of the Tisch Cancer Institute at Icahn School of Medicine at Mount Sinai, discusses results from a phase II trial designed to test gemcitabine and cisplatin plus nivolumab as neoadjuvant therapy in patients with muscle-invasive bladder cancer and to better predict benefit in those who opted out of cystectomy (Abstract 4503).
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).
Martin Reck, MD, PhD, of LungenClinic, discusses a 2-year update of the CheckMate 9LA study, which sought to determine whether nivolumab plus ipilimumab combined with two cycles of chemotherapy is more effective than four cycles of chemotherapy alone as a first-line treatment for patients with stage IV non–small cell lung cancer (Abstract 9000).
