Popis: Summary: Background: We studied the poorly-known dynamics of circulating DNA (cir-nDNA), as monitored prospectively over an extended post-surgery period, in patients with cancer. Methods: On patients with stage III colon cancer (N = 120), using personalised molecular tags we carried out the prospective, multicenter, blinded cohort study of the post-surgery serial analysis of cir-nDNA concentration. 74 patients were included and 357 plasma samples tested. Findings: During post-operative follow-up, the patients’ median cir-nDNA concentration was greater (P 18 months post-surgery, the data suggest that the persistence of NETs formation is not due to the adjuvant CT. Interpretation: (1), Given the inter-patient heterogeneity, the post-surgery cir-nDNA level cannot be considered a reliable value, and caution must be exercised when determining mutation allele frequency or the mutation status; and (2), specific studies must be undertaken to investigate the possible clinical impact of the persistent, low-grade inflammation resulting from elevated NETs levels, such as observed in these post-surgery patients, given that such levels are known to potentially induce adverse cardiovascular or thrombotic events. Funding: This work was supported by the H2020 European ERA-NET grant on Translational Cancer Research (TRANSCAN-2).
