Fatima Cardoso, MD, on Breast Cancer: MammaPrint as Guidance for Adjuvant Chemotherapy

Fatima Cardoso, MD, of Lisbon’s Champalimaud Cancer Center, discusses the long-term results of MINDACT, a large prospective trial showing the clinical utility of the 70-gene signature MammaPrint for adjuvant chemotherapy decision-making. The primary distant metastasis–free survival endpoint at 5 years continued to be met in chemotherapy-untreated women with clinical-high/genomic-low risk disease (Abstract 506).

Nancy U. Lin, MD, on Metastatic Breast Cancer: Tucatinib, Trastuzumab, and Capecitabine

Nancy U. Lin, MD, of Dana-Farber Cancer Institute, discusses the HER2CLIMB study of patients with previously treated HER2-positive metastatic breast cancer that had metastasized to the brain. Adding tucatinib to trastuzumab and capecitabine doubled the intracranial response rate and reduced the risk of death by nearly half, compared with trastuzumab plus capecitabine (Abstract 1005).
