Melinda L. Telli, MD, on Breast Cancer: Neoadjuvant Talazoparib for Early HER2-Negative Disease
2021 ASCO Annual Meeting
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).

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).

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).

Sibylle Loibl, MD, PhD, of the German Breast Group, discusses results from the phase III GeparNUEVO study, which investigated neoadjuvant durvalumab in addition to anthracycline/taxane-based neoadjuvant chemotherapy in patients with early triple-negative breast cancer (Abstract 506).

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).

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).
