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).

Douglas B. Johnson, MD, of Vanderbilt University Medical Center, discusses three important melanoma abstracts: the need for more than two doses of nivolumab plus ipilimumab in combination immunotherapy; antitumor activity for low-dose ipilimumab with pembrolizumab after disease progression on PD-1 antibodies; and ipilimumab alone or in combination with anti–PD-1 therapy for metastatic disease resistant to PD-1 monotherapy (Abstracts 10003, 10004, and 10005).

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).

Meletios A. Dimopoulos, MD, of the University of Athens, discusses phase III results from the BOSTON trial, which showed that once-weekly selinexor, bortezomib, and dexamethasone significantly improved progression-free survival and overall response rates compared with twice-weekly bortezomib and dexamethasone in patients previously treated for multiple myeloma (Abstract 8501).

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).

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.
