Thierry André, MD, of Hôpital Saint-Antoine, discusses final overall survival data for the phase III KEYNOTE-177 study, which confirmed pembrolizumab as a new standard of care for first-line treatment of patients with microsatellite instability–high/mismatch repair–deficient metastatic colorectal cancer (Abstract 3500).
Karim Fizazi, MD, PhD, of Institut Gustave Roussy, discusses first results from the phase III PEACE1 trial, which showed that abiraterone plus androgen-deprivation therapy and docetaxel improves radiographic progression-free survival in men with de novo metastatic prostate cancer (Abstract 5000).
Brian I. Rini, MD, of Vanderbilt University, discusses findings from KEYNOTE-426, the longest follow-up of a checkpoint inhibitor (pembrolizumab) combined with a VEGF/VEGFR inhibitor (axitinib) for first-line clear cell renal cell carcinoma. The trial results continue to support this combination as a standard of care for patients with previously untreated disease (Abstract 4500).
Brian K. Link, MD, of the University of Iowa Carver College of Medicine, reviews three abstracts on state-of-the-art therapies for mantle cell lymphoma: bendamustine, rituximab, lenalidomide and bortezomib; treatment patterns and outcomes for previously untreated patients; and venetoclax, lenalidomide, and rituximab in newly diagnosed disease (Abstracts 7503, 7504, and 7505).
Priya Rastogi, MD, of the University of Pittsburgh, discusses results from the NRG Oncology/NSABP B-42 trial, which evaluated the utility of the 70-gene MammaPrint assay in predicting the benefit of extended letrozole therapy in patients who had completed 5 years of adjuvant endocrine therapy (Abstract 502).
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses first phase III results from a prospective high-risk cohort of patients with luminal breast cancer, which showed a good prognosis in some women with more than four positive lymph nodes and low recurrence scores. The study also showed that a lower postendocrine Ki67 index and limited tumor burden may be promising criteria for chemotherapy de-escalation strategies, even in patients with high recurrence scores (Abstract 504).
