Sara A. Hurvitz, MD, on Breast Cancer: Four Major Studies on Trastuzumab, Pertuzumab, Anthracyclines, and Chemotherapy De-escalation
ASCO20 Virtual Scientific Program
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).

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).

Christopher Nutting, MD, PhD, of the Royal Marsden Hospital and Institute of Cancer Research, discusses phase III results from the first study to demonstrate the functional benefit of swallow-sparing intensity-modulated radiotherapy in oro- and hypopharyngeal cancers (Abstract 6508).

Thierry André, MD, of Hôpital Saint-Antoine, discusses the phase III results from KEYNOTE-177, which showed that, compared with standard chemotherapy of FOLFOX or FOLFIRI, pembrolizumab doubled median progression-free survival, from 8.2 months to 16.5 months, in patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract LBA4).

Jeffrey A. Meyerhardt, MD, MPH, of Dana-Farber Cancer Institute, discusses results from the CALGB/SWOG 80702 trial of celecoxib plus standard adjuvant therapy with fluorouracil, leucovorin, and oxaliplatin (FOLFOX). Adding celecoxib to standard chemotherapy did not significantly improve disease-free or overall survival (Abstract 4003).

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).
