Geoffrey J. Lindeman, MBBS, PhD, on Breast Cancer: Venetoclax and Fulvestrant in ER-Positive, HER2-Negative Disease
2021 ASCO Annual Meeting
Geoffrey J. Lindeman, MBBS, PhD, of Peter MacCallum Cancer Centre, discusses results from the phase II VERONICA study, which compared venetoclax plus fulvestrant with fulvestrant alone in women with estrogen receptor–positive, HER2-negative, locally advanced or metastatic breast cancer who experienced disease recurrence or progression during or after treatment with CDK4/6 inhibitor therapy (Abstract 1004).

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).

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).

Byoung Chul Cho, MD, PhD, of the Yonsei Cancer Center, discusses study results that showed treatment with the EGFR-MET bispecific antibody amivantamab plus the EGFR inhibitor lazertinib yielded responses in 36% of chemotherapy-naive patients with non–small cell lung cancer whose disease progressed on osimertinib. Genetic biomarkers may be able to identify patients most likely to benefit from the combination regimen (Abstract 9006).

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).

Michael J. Morris, MD, of Memorial Sloan Kettering Cancer Center, discusses phase III results of the VISION study, which showed that lutetium-177–PSMA-617 (LuPSMA), a targeted radioligand therapy, plus standard-of-care treatment improves radiographic progression-free survival and extends overall survival compared with standard of care alone in men with metastatic castration-resistant prostate cancer (Abstract LBA4).
