Circulating tumor DNA dynamics in patients with hormone receptor-positive/human epidermal growth factor receptor 2-negative early breast cancer assessed using an ultrasensitive tumor-informed assay
{{output}}
Background: Circulating tumor DNA (ctDNA) in early breast cancer (EBC) is prognostic for distant relapses. The ctDNA dynamics in hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative EBC, which i... ...
