Circulating Tumor DNA in Resected Colorectal Liver Metastases: From Minimal Residual Disease Detection to Treatment Guidance—A Systematic Review
Background: Circulating tumor DNA (ctDNA) has emerged as a potential marker of minimal residual disease (MRD) after resection of colorectal liver metastases (CRLM), but its prognostic value and possible role in guiding postoperative management remain uncertain. This systematic review evaluated the available evidence on...
