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).
Sara A. Hurvitz, MD, of UCLA’s David Geffen School of Medicine, summarizes four breast cancer studies: KATHERINE, on adjuvant trastuzumab vs trastuzumab in patients with residual invasive disease after neoadjuvant therapy for HER2-positive breast cancer; KAITLIN, on trastuzumab emtansine and pertuzumab vs trastuzumab, pertuzumab, and taxane after anthracyclines as adjuvant therapy for high-risk HER2-positive early breast cancer; TRAIN-2, on neoadjuvant chemotherapy with or without anthracyclines for HER2-positive disease; and PHERGain, on chemotherapy de-escalation using an FDG-PET/CT and pathologic response–adapted strategy in HER2-positive early breast cancer (Abstracts 500, 501, 502, and 503).
Paul G. Richardson, MD, of Dana-Farber Cancer Institute, discusses early results on a cereblon E3 ligase modulator agent combined with dexamethasone in patients with relapsed or refractory multiple myeloma, with an overall response rate of 48%. The study is ongoing to further optimize dose and schedule (Abstract 8500).
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).
David C. Fajgenbaum, MD, MBA, of the University of Pennsylvania, who trained as an oncologist, summarizes his opening lecture, a dramatic story of his battle against Castleman, a disease of the lymph nodes, his multiple near-death experiences, and the path that led him to develop a cooperative research effort making a difference for him and other patients with this idiopathic orphan illness.
Leora Horn, MD, of Vanderbilt University, discusses the results of the TERAVOLT study, launched by the Thoracic Cancers International COVID-19 Collaboration. It examined the impact of specific chemotherapy and immunotherapy regimens on hospitalization and risk of death in patients with thoracic malignancies who are also infected with COVID-19 (Abstract LBA111).
