Matt D. Galsky, MD, of the Tisch Cancer Institute at Icahn School of Medicine at Mount Sinai, discusses results from a phase II trial designed to test gemcitabine and cisplatin plus nivolumab as neoadjuvant therapy in patients with muscle-invasive bladder cancer and to better predict benefit in those who opted out of cystectomy (Abstract 4503).
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).
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).
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).
Vamsidhar Velcheti, MD, of New York University, discusses overall survival and exploratory subgroup analyses from the phase II CodeBreaK 100 trial, which evaluated the use of sotorasib in pretreated KRAS G12C–mutant non–small cell lung cancer (Abstract 9003).
