Tissue-Free vs Tumor-Informed ctDNA Assays for Molecular Residual Disease Detection in Early Triple Negative Breast Cancer
JAMA Oncology
A well-designed prospective prognostic study in a defined population showing tissue-free ctDNA strongly predicts recurrence and performs comparably to tumor-informed assays, but uses surrogate endpoints (lead time, detection concordance) rather than direct clinical outcomes, and requires confirmation in a prospective trial.
