The aim of this study was to evaluate phenotypic and genetic heterogeneity of circulating epithelial cells (CECs) based on asialoglycoprotein receptor 1 (ASGR1) and miR-122-5p expression as potential diagnostic and prognostic tools in patients with hepatocellular carcinoma (HCC) and liver cirrhosis (LC).<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> Peripheral blood samples were extracted from LC and HCC patients at different disease stages. CECs were isolated using positive immunomagnetic selection. Genetic and phenotypic characterization was validated by double immunocytochemistry for cytokeratin (CK) and ASGR1 or by <jats:italic>in situ<\/jats:italic> hybridization with miR-122-5p and CECs were visualized by confocal microscopy.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The presence of CECs increased HCC risk by 2.58-fold, however, this was only significant for patients with previous LC (<jats:italic>p<\/jats:italic> = 0.028) and not for those without prior LC (<jats:italic>p<\/jats:italic> = 0.23). Furthermore, the number of CECs lacking ASGR1 expression correlated significantly with HCC incidence and absence of miR-122-5p expression (<jats:italic>p<\/jats:italic> = 0.014; <jats:italic>r<\/jats:italic> = 0.23). Finally, overall survival was significantly greater for patients at earlier cancer stages (<jats:italic>p<\/jats:italic> = 0.018), but this difference was only maintained in the group with the presence of CECs (<jats:italic>p<\/jats:italic> = 0.021) whereas progression-free survival was influenced by the absence of ASGR1 expression.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> Identification and characterization of CECs by ASGR1 and\/or miR-122-5p expression may be used as a risk-stratification tool in LC patients, as it was shown to be an independent prognostic and risk-stratification marker in LC and early disease stage HCC patients.<\/jats:p>","DOI":"10.3389\/fmolb.2022.1074277","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T05:13:40Z","timestamp":1669612420000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":15,"title":["Hepatocellular carcinoma risk-stratification based on ASGR1 in circulating epithelial cells for cancer interception"],"prefix":"10.3389","volume":"9","author":[{"given":"Amparo","family":"Roa-Colomo","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda \u00c1ngeles","family":"L\u00f3pez Garrido","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pilar","family":"Molina-Vallejo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Angela","family":"Rojas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mercedes Gonz\u00e1lez","family":"Sanchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Violeta","family":"Aranda-Garc\u00eda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Salmeron","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manuel","family":"Romero-Gomez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jordi","family":"Muntane","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Javier","family":"Padillo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose Mar\u00eda","family":"Alamo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose A.","family":"Lorente","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar\u00eda Jos\u00e9","family":"Serrano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
