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).

Andrew Tutt, PhD, MBChB, of the Institute of Cancer Research, London, discusses findings from the phase III OlympiA trial, which showed that adjuvant olaparib, a PARP inhibitor, following adjuvant or neoadjuvant chemotherapy, may improve invasive disease–free survival in patients with germline BRCA-mutated and high-risk HER2-negative early breast cancer, which might lead to a new indication in this setting (Abstract LBA1).

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).

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).

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).

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).
