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).
Melinda L. Telli, MD, of Stanford University, discusses results of a phase II study on neoadjuvant talazoparib in germline BRCA1/2 mutation–positive, early HER2-negative breast cancer. In this setting, talazoparib monotherapy was active and yielded pathologic complete response rates comparable to those observed with combination anthracycline and taxane-based chemotherapy regimens (Abstract 505).
Cathy Eng, MD, of Vanderbilt-Ingram Cancer Center, discusses two abstracts from a session she co-chaired: the phase II DEEPER trial, which explored the use of FOLFOXIRI plus cetuximab vs FOLFOXIRI plus bevacizumab as first-line treatment in metastatic colorectal cancer with RAS wild-type tumors; and the phase II FIRE-4.5 study, which investigated FOLFOXIRI plus either bevacizumab or cetuximab as first-line treatment of BRAF V600E–mutant advanced disease (Abstracts 3501 and 3502).
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).
Ingrid A. Mayer, MD, of Vanderbilt University Medical Center, discusses phase III results from a trial that showed patients with triple-negative breast cancer who had residual invasive disease after neoadjuvant chemotherapy had lower-than-expected invasive disease–free survival, regardless of study treatment with platinum-based chemotherapy or capecitabine (Abstract 605).
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).
