Nadia Harbeck, MD, PhD, on Early Breast Cancer: Benefit of a De-escalated Regimen
2021 ASCO Annual Meeting
Nadia Harbeck, MD, PhD, of Ludwig Maximilian University of Munich, discusses results from the ADAPT HR–/HER2+ trial, which showed, for the first time, improved pathologic complete response and survival in patients with early breast cancer who were treated weekly with a de-escalated 12-week regimen of neoadjuvant paclitaxel plus pertuzumab and trastuzumab (Abstract 503).
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).
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).
Terry P. Mamounas, MD, MPH, of the University of Florida Health Cancer Center, discusses results from the NRG Oncology/NSABP B-42 study, which examined the Breast Cancer Index and its ability to predict whether extended treatment with letrozole benefits patients with hormone receptor–positive breast cancer (Abstract 501).
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).
Bijal D. Shah, MD, of the H. Lee Moffitt Cancer Center, discusses phase II results of the ZUMA-3 study, which evaluated brexucabtagene autoleucel (KTE-X19), an anti-CD19 CAR T-cell therapy, in adults with relapsed or refractory B-cell acute lymphoblastic leukemia (Abstract 7002).
