Thierry André, MD, on Colorectal Cancer: Pembrolizumab vs Chemotherapy for Metastatic Disease
ASCO20 Virtual Scientific Program
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).

Michael S. Hofman, MBBS, of the Peter MacCallum Cancer Centre, discusses phase II results from the ANZUP 1603 trial, which showed that in men with docetaxel-treated metastatic castration-resistant prostate cancer, LuPSMA was more active than cabazitaxel, with relatively fewer grade 3 and 4 adverse events and a more favorable PSA progression-free-survival (Abstract 5500).

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).

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).

Nancy U. Lin, MD, of Dana-Farber Cancer Institute, discusses the HER2CLIMB study of patients with previously treated HER2-positive metastatic breast cancer that had metastasized to the brain. Adding tucatinib to trastuzumab and capecitabine doubled the intracranial response rate and reduced the risk of death by nearly half, compared with trastuzumab plus capecitabine (Abstract 1005).

Fatima Cardoso, MD, of Lisbon’s Champalimaud Cancer Center, discusses the long-term results of MINDACT, a large prospective trial showing the clinical utility of the 70-gene signature MammaPrint for adjuvant chemotherapy decision-making. The primary distant metastasis–free survival endpoint at 5 years continued to be met in chemotherapy-untreated women with clinical-high/genomic-low risk disease (Abstract 506).
