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).

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).
The ASCO Post Staff
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).

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).

Neal D. Shore, MD, of the Carolina Urologic Research Center, discusses phase III results of the HERO study, which showed relugolix achieved castration as early as day 4 and was superior to leuprolide in sustained testosterone suppression, testosterone recovery after discontinuation, and reduction in cardiovascular side effects (Abstract 5602).
