Peter Reichardt, MD, PhD, of Helios Klinikum Berlin-Buch, discusses the 10-year survival analysis of 3 years vs 1 year of adjuvant imatinib for patients with high-risk gastrointestinal stromal tumor. The study found that about 50% of deaths can be avoided with longer imatinib treatment (Abstract 11503).
Seema A. Khan, MD, MPH, of the Lynn Sage Comprehensive Breast Center, discusses phase III trial results showing that in newly diagnosed metastatic stage IV breast cancer, locoregional treatment of the primary tumor did not offer a greater survival benefit than systemic therapy (Abstract LBA2).
Sara A. Hurvitz, MD, of UCLA’s David Geffen School of Medicine, summarizes four breast cancer studies: KATHERINE, on adjuvant trastuzumab vs trastuzumab in patients with residual invasive disease after neoadjuvant therapy for HER2-positive breast cancer; KAITLIN, on trastuzumab emtansine and pertuzumab vs trastuzumab, pertuzumab, and taxane after anthracyclines as adjuvant therapy for high-risk HER2-positive early breast cancer; TRAIN-2, on neoadjuvant chemotherapy with or without anthracyclines for HER2-positive disease; and PHERGain, on chemotherapy de-escalation using an FDG-PET/CT and pathologic response–adapted strategy in HER2-positive early breast cancer (Abstracts 500, 501, 502, and 503).
Roy S. Herbst, MD, PhD, of Yale Cancer Center, discusses data from the ADAURA study, which showed that compared with placebo, osimertinib as adjuvant therapy after complete tumor resection reduced the risk of disease recurrence or death by 79% in patients with non–small cell lung cancer (Abstract LBA5).
Cynthia X. Ma, MD, PhD, of Washington University, discusses results from the ALTERNATE trial, which showed neither fulvestrant nor fulvestrant plus anastrozole significantly improved endocrine-sensitive disease rate compared with anastrozole alone in postmenopausal patients with locally advanced estrogen receptor–positive, HER2-negative breast cancer (Abstract 504).
Nikhil C. Munshi, MD, of Dana-Farber Cancer Institute, discusses initial results from the KarMMa tria, showing that idecabtagene vicleucel, a B-cell maturation antigen-targeted CAR T-cell therapy, demonstrated deep and durable responses in patients with heavily pretreated relapsed or refractory multiple myeloma. Efficacy and safety data support a favorable clinical benefit-risk profile across the target dose range (Abstract 8503).
