Abstract

Background. Hepatocellular carcinoma (HCC) is a frequent diagnosis in patients with chronic liver disease (CLD) and a newly identified liver lesion, although benign diseases may also be responsible for this finding. Objective. To evaluate the characteristics of focal liver lesions in a population of patients with CLD not under surveillance for HCC in the Middle East. Methods. We performed a cross-sectional study evaluating 77 patients with CLD and a focal liver lesion identified during ultrasonography. Patients’ characteristics were analyzed on the basis of the final diagnosis (HCC versus benign lesions). Results. The most frequent diagnosis was HCC (64.9%). These patients were older (median age 64 versus 55 years, ) and cirrhotics (80.0% versus 51.9%, ), with multinodular lesions (58.0% versus 29.6%, ) and portal vein thrombosis (24.0% versus 0%, ) compared to patients with benign lesions. Prevalence of elevated alpha-fetoprotein (>10 ng/mL) was similar in both groups (80.0% versus 88.9%, ). Cirrhosis (odds ratio: 3.283) and multinodularity (odds ratio: 2.898) were independently associated with HCC. Conclusions. HCC is the most common diagnosis in Middle-Eastern patients with CLD and a liver lesion identified outside HCC surveillance programs, especially in cirrhotic patients. In these patients, elevated alpha-fetoprotein does not differentiate HCC from benign lesions.
