Julie Gralow, MD, discusses the use of patient-reported outcomes in the SWOG S1105 trial and different factors for patients with early-stage breast cancer on an aromatase inhibitor to see if they could predict who may be more likely to stop taking treatment early.
“With demonstration of efficacy in biomarker-selected BRCA-like phenotype triple-negative breast cancer, the results of this trial are a very positive step toward expanding the role of PARP inhibitors beyond germline BRCA in breast cancer."
Javier Cortes, MD, PhD, discusses the data from the phase 3 KEYNOTE-355 trial of pembrolizumab and chemotherapy versus placebo and chemotherapy for previously untreated patients with locally recurrent inoperable or metastatic triple-negative breast cancer.
"We are disappointed [with] this outcome. Breast cancer is a leading cause of death around the world and delaying or preventing the development of metastatic disease is a significant unmet need. PALLAS is a large study with many subgroups and we are actively collaborating to determine if there are patients who may benefit from adjuvant treatment with the palbociclib combination."
"Pembrolizumab and chemotherapy demonstrated a statistically significant and clinically meaningful improvement in PFS as compared with chemotherapy alone for the first-line treatment of metastatic TNBC with a PD-L1 CPS of 10 or higher tumors."
The addition of tucatinib to treatment with trastuzumab and capecitabine resulted in more than a 60% reduction in the risk of central nervous system progression or death in both patients with previously treated HER2-positive metastatic breast cancer who have active or stable brain metastases.
