Early circulating tumor DNA dynamics and clonal selection with palbociclib and fulvestrant for breast cancer
23 Feb 2018
Abstract excerpt
CDK4/6 inhibition substantially improves progression-free survival (PFS) for women with advanced estrogen receptor-positive breast cancer, although there are no predictive biomarkers. Early changes in circulating tumor DNA (ctDNA) level may provide early response prediction, but the impact of tumor heterogeneity is unknown. Here we use plasma samples from patients in the randomized phase III PALOMA-3 study of...
