Alberto F. Sobrero, MD, of the Ospedale San Martino, discusses final results of the IDEA study, which supported the use of 3 months of adjuvant CAPOX, vs 6 months, for most patients with stage III colon cancer. The shorter treatment duration reduced toxicity, inconvenience, and cost (Abstract 4004).
Meletios A. Dimopoulos, MD, of the University of Athens, discusses phase III results from the BOSTON trial, which showed that once-weekly selinexor, bortezomib, and dexamethasone significantly improved progression-free survival and overall response rates compared with twice-weekly bortezomib and dexamethasone in patients previously treated for multiple myeloma (Abstract 8501).
Michael S. Hofman, MBBS, of the Peter MacCallum Cancer Centre, discusses phase II results from the ANZUP 1603 trial, which showed that in men with docetaxel-treated metastatic castration-resistant prostate cancer, LuPSMA was more active than cabazitaxel, with relatively fewer grade 3 and 4 adverse events and a more favorable PSA progression-free-survival (Abstract 5500).
Lakshmi Nayak, MD, of Dana-Farber Cancer Institute, reviews two key abstracts on newly diagnosed primary central nervous system lymphoma and treatment with whole-brain radiotherapy, methotrexate, temozolomide, rituximab, procarbazine, vincristine, and cytarabine (Abstracts 2500 and 2501).
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).
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).
