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).

Michael J. Morris, MD, of Memorial Sloan Kettering Cancer Center, discusses phase III data from the CONDOR trial, which showed that PSMA-targeted PET scans detected and localized occult disease in most men with biochemically recurrent prostate cancer presenting with negative or equivocal conventional imaging findings (Abstract 5501).

Howard A. Burris III, MD, FACP, FASCO, Immediate Past President of ASCO and current Society Board Chair, talks about how the meeting went, with its record-breaking attendance and new format.

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).

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).

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).
