Sumanta K. Pal, MD, of City of Hope, discusses results from a phase II study that sought to determine whether adding berzosertib, a selective ATR inhibitor, to the standard upfront chemotherapy regimen of cisplatin with gemcitabine may improve outcomes in patients with metastatic urothelial carcinoma (Abstract 4507).
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).
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).
Ann S. LaCasce, MD, of Dana-Farber Cancer Institute, discusses results from the CALGB 50801 Alliance study, which showed that a PET scan–adapted approach may reduce the need for radiation treatment and may improve progression-free outcomes in patients with stage I/II bulky classic Hodgkin lymphoma (Abstract 7507).
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).
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).
