Abstract
Hepatocellular carcinoma (HCC) is the most common malignant liver tumor. Between 80% and 90% of cases occur in patients with advanced chronic liver disease, traditionally of viral etiology. Its clinical manifestations are very nonspecific and, in most cases, it is asymptomatic. Early diagnosis of HCC is essential, hence the screening strategies based on periodic abdominal ultrasound in patients with chronic liver disease. A peculiarity of this tumor is the possibility of making a non-invasive radiological diagnosis based on dynamic imaging tests (computed tomography or magnetic resonance imaging), reserving a histological study for cases with inconclusive results. The prognosis of HCC depends on the tumor stage as well as characteristics of the underlying liver disease and the patient's functional status, which will determine the different treatment options.
