Nadia Harbeck, MD, PhD, on Luminal Breast Cancer: Prognostic Impact of Recurrence Score, Endocrine Response, and Other Factors
2021 ASCO Annual Meeting
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).

Massimo Cristofanilli, MD, of the Feinberg School of Medicine at Northwestern University, discusses updated overall survival data from the phase III PALOMA-3 trial of palbociclib plus fulvestrant in women with hormone receptor–positive, HER2-negative advanced breast cancer (Abstract 1000).

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).

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).

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).
