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).
David R. Wise, MD, PhD, of New York University Perlmutter Cancer Center, summarizes three important studies in prostate cancer: circulating tumor cell count as a prognostic marker of PSA response and progression in metastatic castration-sensitive disease; new phenotypic subtypes; and how circulating tumor DNA dynamics associate with treatment response and radiologic progression-free survival (Abstracts 5506, 5507, and 5508).
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).
Thierry André, MD, of Hôpital Saint-Antoine, discusses the phase III results from KEYNOTE-177, which showed that, compared with standard chemotherapy of FOLFOX or FOLFIRI, pembrolizumab doubled median progression-free survival, from 8.2 months to 16.5 months, in patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract LBA4).
Christopher Nutting, MD, PhD, of the Royal Marsden Hospital and Institute of Cancer Research, discusses phase III results from the first study to demonstrate the functional benefit of swallow-sparing intensity-modulated radiotherapy in oro- and hypopharyngeal cancers (Abstract 6508).
Shaji Kumar, MD, of the Mayo Clinic, discusses findings from the ENDURANCE trial, which showed bortezomib, lenalidomide, and dexamethasone should remain the standard of care in patients with newly diagnosed standard- or intermediate-risk multiple myeloma, for whom early autologous stem cell transplant is not intended (Abstract LBA3).
