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).

Brian I. Rini, MD, of Vanderbilt University, discusses findings from KEYNOTE-426, the longest follow-up of a checkpoint inhibitor (pembrolizumab) combined with a VEGF/VEGFR inhibitor (axitinib) for first-line clear cell renal cell carcinoma. The trial results continue to support this combination as a standard of care for patients with previously untreated disease (Abstract 4500).

Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, discusses phase III results from KEYNOTE-564, which evaluated the safety and efficacy of pembrolizumab in the adjuvant treatment of patients with renal cell carcinoma who have undergone nephrectomy for intermediate-high or high-risk disease or no evidence of disease (Abstract LBA5).

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).

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).
