We developed a multiplex ddPCR assay targeting ctDNA with a methylation signature specific for breast tissue (In order to increase sensitivity, we included both sense and antisense targets of The multiplex assay was used for the analysis of plasma samples available from 76 patients at midterm and from 63 patients preoperatively. A total of 19 midterm and 9 preoperative samples displayed positivity for the cancer specific marker Sensitivity of circulating tumor DNA multiplex assay targeting the cancer specific marker
