David R. Wise, MD, PhD, on Novel Biomarkers in Prostate Cancer: Is Tissue the Issue?
ASCO20 Virtual Scientific Program
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).

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).

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).

Eric Zhou, PhD, of Dana-Farber Cancer Institute, discusses an existing online program called SHUTi (Sleep Healthy Using the Internet), that he and his team adapted to the needs of adolescent and young adult cancer survivors. After six online cognitive behavior therapy sessions delivered over 8 weeks, the 22 patients in the study reported a significant reduction in insomnia severity, daytime sleepiness, and fatigue as well as an overall improvement in quality of life.

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).

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).
