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).

Roy S. Herbst, MD, PhD, of Yale Cancer Center, discusses data from the ADAURA study, which showed that compared with placebo, osimertinib as adjuvant therapy after complete tumor resection reduced the risk of disease recurrence or death by 79% in patients with non–small cell lung cancer (Abstract LBA5).

Richard L. Schilsky, MD, Chief Medical Officer of ASCO, talks about some of the most important and practice-changing findings presented this year at the ASCO20 Virtual Scientific Program, including the use of targeted and immunotherapies in earlier lines of therapy, where they have made a significant impact.

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).

Tingyan Shi, MD, PhD, of Zhongshan Hospital, Fudan University, discusses study results that showed secondary cytoreductive surgery in selected patients extended progression-free survival and might contribute to long-term survival (Abstract 6001).

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).
