Methods: A total of 547 patients (mean (SD) age 62.6 (10.3) years, 81.9% were males) were included in this registry study. Data on patient characteristics, etiologies of HCC, laboratory values, and tumor characteristics and stages were recorded at study enrollment. Results: HBV infection (68.2%) was the leading etiology, followed by HCV infection (17.2%), HDV infection (5.5%), alcohol (6.4%), and NAFLD (3.5%), as the major etiologies. Considering that 51.6% of the patients had >5 cm HCC, 44% were Child-Pugh B/C and 57% were BCLC B-D, it appears that a significant group of HCC patients were diagnosed at advanced stages. Of 540 patients, 271 (50.2%) were referred or applied with the diagnosis of HCC. Patients with HCC at presentation had larger tumor size (median (min-max) 6.6 (0-30) vs. 4.8 (0-90) cm, P<.001) and more advanced BCLC stage (Stage C-D in 40.8% vs. 26.4%, respectively, P=.005), compared to patients who were diagnosed during follow-up. Conclusions: Our findings revealed that HBV infection was the leading etiology and a moderate-to-advanced disease was evident in more than half of patients at the time of diagnosis. HCC patients diagnosed at follow-up had smaller tumor size and earlier BCLC stage.eninfo:eu-repo/semantics/openAccessHepatocellular carcinomaEpidemiologyRisk factorsPrognostic factorsScreeningTurkeyArticle321210191028WOS:0007277477000042-s2.0-851224989005063483487639210.5152/tjg.2021.201171Q3Q4
