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).
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).
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).
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).
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).
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).
