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).
Rachel E. Sanborn, MD, of the Providence Cancer Institute, discusses three key abstracts on EGFR-mutated non–small cell lung cancer: a final overall survival analysis of bevacizumab plus erlotinib; concurrent osimertinib plus gefitinib for first-line treatment; and first-line treatment with a tyrosine kinase inhibitor with or without aggressive upfront local radiation therapy (Abstracts 9506, 9507, 9508).
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).
Michael J. Morris, MD, of Memorial Sloan Kettering Cancer Center, discusses phase III data from the CONDOR trial, which showed that PSMA-targeted PET scans detected and localized occult disease in most men with biochemically recurrent prostate cancer presenting with negative or equivocal conventional imaging findings (Abstract 5501).
Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, talks with Thomas Powles, MD, PhD, of Queen Mary University of London, about the first study to demonstrate a survival advantage with avelumab for metastatic urothelial cancer. In the trial, avelumab improved median overall survival by 21.4 months compared with 14.3 months with best supportive care (Abstract LBA1).
