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).

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).

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).

Rana R. McKay, MD, of the University of California, San Diego, discusses the results of a phase II trial of intense neoadjuvant hormone therapy followed by radical prostatectomy in men with high-risk prostate cancer. The data show that 21% of patients had a favorable pathologic response (Abstract 5503).

Shaji Kumar, MD, of the Mayo Clinic, discusses findings from the ENDURANCE trial, which showed bortezomib, lenalidomide, and dexamethasone should remain the standard of care in patients with newly diagnosed standard- or intermediate-risk multiple myeloma, for whom early autologous stem cell transplant is not intended (Abstract LBA3).

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).
