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).

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).
The ASCO Post Staff
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).

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).

Neeraj Agarwal, MD, of Huntsman Cancer Institute at the University of Utah, discusses phase III data from the SWOG S1216 trial, which evaluated the clinical benefit of using androgen-deprivation therapy with either orteronel (or TAK-700, a CYP17 inhibitor) or bicalutamide in patients with newly diagnosed metastatic hormone-sensitive prostate cancer (Abstract 5001).

Taiga Nishihori, MD, of the H. Lee Moffitt Cancer Center and Research Institute, discusses the outcome of a trial that explored maintenance therapy with ixazomib after allogeneic hematopoietic cell transplantation in patients with high-risk multiple myeloma. Toxicities unrelated to the maintenance treatment forced the trial to close prematurely (Abstract 7003).
