Alpha-fetoprotein (AFP), a widely used and accessible tumoral marker, has limited performance in the early detection of HCC among high-risk populations. This study aims to evaluate the potential added value of ccfDNA (circulating cell-free DNA) fragment size, alone or in a multiparameter panel, using accessible, feasible ccfDNA analysis. Methods: A prospective cohort of 125 patients with chronic liver disease was analyzed. Patients with incomplete clinical or laboratory data and patients without cirrhosis were excluded from the final analysis. Nonparametric tests, logistic regression and ROC curve analysis were performed. ccfDNA fragment size was measured using on-chip electrophoresis. Results: ccfDNA fragment size was significantly lower in the cirrhosis-HCC subgroup compared to the cirrhosis-only subgroup (p &lt; 0.001). While AFP remains an independent predictor of HCC among cirrhosis patients, ccfDNA fragment size did not prove to be an independent predictor in this cohort. AUROC (area under the receiver operating characteristic curve) analysis revealed that a combined model of AFP, age, liver reserve, and ccfDNA fragment size did not perform better than the corresponding panel without ccfDNA. Moreover, after DeLong comparison, the difference between the two AUROCs proved statistically insignificant. Age and platelet count remain the strongest independent predictors in our exploratory cohort. Conclusions: Although ccfDNA fragment size proved to be lower in the HCC subgroup, its statistical significance fades when included into a multimarker panel. However, all panels should undergo further validation in a larger cohort, in order to better assess the individual contribution of each parameter and to discriminate between added diagnostic value and confounding effect of age and liver reserve parameters.<\/jats:p>","DOI":"10.3390\/life16071079","type":"journal-article","created":{"date-parts":[[2026,6,29]],"date-time":"2026-06-29T00:54:42Z","timestamp":1782694482000},"page":"1079","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Exploring the Predictive Value of Circulating Cell-Free DNA Within a Multiparameter Panel for Hepatocellular Carcinoma Detection"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0226-3037","authenticated-orcid":false,"given":"Ioana","family":"Manea","sequence":"first","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 020956 Bucharest, Romania"},{"name":"Center of Excellence in Translational Medicine, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7805-5920","authenticated-orcid":false,"given":"Speranta Maria","family":"Iacob","sequence":"additional","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 020956 Bucharest, Romania"},{"name":"Center of Excellence in Translational Medicine, Fundeni Clinical Institute, 022328 Bucharest, Romania"},{"name":"Center for Digestive Diseases and Liver Transplant, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8545-310X","authenticated-orcid":false,"given":"Razvan","family":"Iacob","sequence":"additional","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 020956 Bucharest, Romania"},{"name":"Center of Excellence in Translational Medicine, Fundeni Clinical Institute, 022328 Bucharest, Romania"},{"name":"Center for Digestive Diseases and Liver Transplant, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-1233-3118","authenticated-orcid":false,"given":"Alina-Veronica","family":"Ghionescu","sequence":"additional","affiliation":[{"name":"Center of Excellence in Translational Medicine, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2617-4629","authenticated-orcid":false,"given":"Andrei","family":"Sorop","sequence":"additional","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 020956 Bucharest, Romania"},{"name":"Center of Excellence in Translational Medicine, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roxana Elena","family":"Saizu","sequence":"additional","affiliation":[{"name":"Center for Digestive Diseases and Liver Transplant, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daria-Ana-Arina","family":"Gheorghe","sequence":"additional","affiliation":[{"name":"Center for Digestive Diseases and Liver Transplant, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Delia","family":"Prisecariu","sequence":"additional","affiliation":[{"name":"Center for Digestive Diseases and Liver Transplant, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5275-8938","authenticated-orcid":false,"given":"Simona Olimpia","family":"Dima","sequence":"additional","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 020956 Bucharest, Romania"},{"name":"Center of Excellence in Translational Medicine, Fundeni Clinical Institute, 022328 Bucharest, Romania"},{"name":"Center for Digestive Diseases and Liver Transplant, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liliana Simona","family":"Gheorghe","sequence":"additional","affiliation":[{"name":"Carol Davila University of Medicine and Pharmacy, 020956 Bucharest, Romania"},{"name":"Center of Excellence in Translational Medicine, Fundeni Clinical Institute, 022328 Bucharest, Romania"},{"name":"Center for Digestive Diseases and Liver Transplant, Fundeni Clinical Institute, 022328 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,27]]},"reference":[{"key":"ref_1","unstructured":"International Agency for Research on Cancer (IARC) (2026, April 28).
