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).
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).
Eric Zhou, PhD, of Dana-Farber Cancer Institute, discusses an existing online program called SHUTi (Sleep Healthy Using the Internet), that he and his team adapted to the needs of adolescent and young adult cancer survivors. After six online cognitive behavior therapy sessions delivered over 8 weeks, the 22 patients in the study reported a significant reduction in insomnia severity, daytime sleepiness, and fatigue as well as an overall improvement in quality of life.
Nancy U. Lin, MD, of Dana-Farber Cancer Institute, discusses the HER2CLIMB study of patients with previously treated HER2-positive metastatic breast cancer that had metastasized to the brain. Adding tucatinib to trastuzumab and capecitabine doubled the intracranial response rate and reduced the risk of death by nearly half, compared with trastuzumab plus capecitabine (Abstract 1005).
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).
Nirav Niranjan Shah, MD, of the Medical College of Wisconsin, explores whether autologous transplantation, in patients with relapsed diffuse large B-cell lymphoma who achieve only a PET/CT-positive partial remission, is appropriate in the era of CAR T-cell therapy (Abstract 8000).
