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).
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).
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).
Massimo Cristofanilli, MD, of the Feinberg School of Medicine at Northwestern University, discusses updated overall survival data from the phase III PALOMA-3 trial of palbociclib plus fulvestrant in women with hormone receptor–positive, HER2-negative advanced breast cancer (Abstract 1000).
Brian K. Link, MD, of the University of Iowa Carver College of Medicine, reviews three abstracts on state-of-the-art therapies for mantle cell lymphoma: bendamustine, rituximab, lenalidomide and bortezomib; treatment patterns and outcomes for previously untreated patients; and venetoclax, lenalidomide, and rituximab in newly diagnosed disease (Abstracts 7503, 7504, and 7505).
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).
