Erika P. Hamilton, MD, FASCO, of Sarah Cannon Research Institute, talks about a comparison of the efficacy and safety of tucatinib vs placebo combined with trastuzumab and pertuzumab as maintenance therapy for HER2-positive metastatic breast cancer by stratified subgroups (Abstract 1005).
Mali Barbi, MD, MS, of Northwell Health Cancer Institute Center for Women's Cancer, discusses durable survival benefits shown in the NRG-GY018 trial with pembrolizumab and the RUBY trial with dostarlimab for patients with mismatch repair–deficient (dMMR) endometrial cancer.
