Hope S. Rugo, MD, on Metastatic Triple-Negative Breast Cancer: Retrospective Analysis of PD-L1 Immunohistochemistry Assays
2019 San Antonio Breast Cancer Symposium
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses a retrospective analysis on the effectiveness of the VENTANA PD-L1 SP142 assay, the Dako 22C3 assay, and the VENTANA SP263 assay as predictors of response to atezolizumab plus nab-paclitaxel in patients with metastatic triple-negative breast cancer (Abstract PD1-07).
Sara M. Tolaney, MD, MPH, of Dana-Farber Cancer Institute, discusses phase II findings on patients receiving T-DM1 monotherapy as adjuvant treatment for stage I HER2-positive breast cancer, a regimen associated with few recurrences in the study population (Abstract GS1-05).
Marie-Jeanne T.F.D. Vrancken Peeters, MD, PhD, of the Netherlands Cancer Institute, discusses an interim study analysis showing that ultrasound-guided core biopsies of the breast in patients with excellent response on MRI after neoadjuvant systemic therapy may not be accurate enough to safely select patients with pathologic complete response for omission of surgery (Abstract GS5-06).
Belinda Kingston, MB ChB, of the Institute of Cancer Research London, discusses next-generation sequencing results from the plasmaMATCH trial, including the incidence of gene alterations overall, as well as the associations with clinical and pathologic features that may help direct treatment decisions (Abstract GS3-07).
Hope S. Rugo, MD, of the University of California San Francisco Comprehensive Cancer Center, discusses trial data on margetuximab plus chemotherapy, which improved progression-free survival in patients with previously treated HER2-positive metastatic breast cancer when compared with trastuzumab plus chemotherapy. Maturing data comparing overall survival also provides new insights (Abstract GS1-02).
Luca Gianni, MD, of the Fondazione Michelangelo, discusses findings from the NeoTRIP trial on pathologic complete response to neoadjuvant treatment with or without atezolizumab in triple-negative, early high-risk, and locally advanced breast cancer (Abstract GS3-04).
