  • Planned neoadjuvant therapy which includes cytotoxic chemotherapy.
  • Tumor size ≥ 2.1 cm in greatest diameter.
  • Unifocal or multifocal cancer documented to be the same histologic clinical subtype.
  • Clinically node positive or if node negative, any one of the following:
    • TNBC or HER2+ subtype
    • HR+/HER2-negative with at least one of the following:
    • High tumor grade (G3) ii. Ki67 index of 20% or higher iii. High genomic risk (Oncotype DX® (ODX) Breast Recurrence Score of > 25, MammaPrint® High, etc.)
  • Willing and able to comply with the study requirements, which includes the collection of a total of 34 cc (2.5 Tablespoons) of blood for each research blood draw.
  • Available residual tissue from diagnostic biopsy from the breast or an involved ipsilateral lymph node for submission to create a bespoke ctDNA assay.
Critètes d'exclusion
