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).
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).
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).
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).
As Thomas Powles, MD, PhD, of Queen Mary University of London, prepares to deliver his late-breaking presentation at the ASCO20 Virtual Scientific Program (LBA-1), he talks with Christopher Sweeney, MBBS, of Dana-Farber Cancer Institute, about current therapy: PD1/PDL1 inhibition in second-line treatment and as monotherapy in the first-line setting, as well as the concept of maintenance switch.
