Presurgical levels of circulating tumour DNA in patients with resectable chemotherapy-naïve colorectal liver metastases: association with multiorgan recurrence and survival in the MIRACLE cohort.

A cheap blood test measuring tumor DNA before surgery can identify which colorectal cancer patients need closer monitoring after treatment.

Pre-surgical ctDNA measurement using an affordable mFast-SeqS assay independently predicted 3-fold increased risk of poor survival in resectable colorectal liver metastases (n=182). This minimally invasive test could identify high-risk patients upfront before local treatment decisions.
