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).

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).

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).

Merry-Jennifer Markham, MD, ASCO’s Cancer Communications Chair, gives her views on key papers presented at the ASCO20 Virtual Scientific Program, addressing gynecologic malignancies and COVID-19.

Peter Reichardt, MD, PhD, of Helios Klinikum Berlin-Buch, discusses the 10-year survival analysis of 3 years vs 1 year of adjuvant imatinib for patients with high-risk gastrointestinal stromal tumor. The study found that about 50% of deaths can be avoided with longer imatinib treatment (Abstract 11503).

Paul G. Richardson, MD, of Dana-Farber Cancer Institute, discusses early results on a cereblon E3 ligase modulator agent combined with dexamethasone in patients with relapsed or refractory multiple myeloma, with an overall response rate of 48%. The study is ongoing to further optimize dose and schedule (Abstract 8500).
