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).
Eric Jonasch, MD, of The University of Texas MD Anderson Cancer Center, discusses phase II study findings on the oral HIF-2α inhibitor known as MK-6482, which showed efficacy and tolerability in patients with Von Hippel-Lindau (VHL)–associated clear cell renal cell carcinoma as well as responses in other VHL-related lesions (Abstract 5003).
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).
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).
Daniel P. Petrylak, MD, of the Yale Cancer Center, discusses early data on ARV-110, an androgen receptor proteolysis–targeting chimera degrader, demonstrating antitumor activity in metastatic castration-resistant prostate cancer after treatment with enzalutamide and abiraterone (Abstract 3500).
Fatima Cardoso, MD, of Lisbon’s Champalimaud Cancer Center, discusses the long-term results of MINDACT, a large prospective trial showing the clinical utility of the 70-gene signature MammaPrint for adjuvant chemotherapy decision-making. The primary distant metastasis–free survival endpoint at 5 years continued to be met in chemotherapy-untreated women with clinical-high/genomic-low risk disease (Abstract 506).
