Surveillance and Diagnosis of Hepatocellular Carcinoma.
Hepatocellular carcinoma (HCC) is an important cause of cancer-related death worldwide. If the disease is detected early, the treatment is more likely to be curative. This article discusses the current evidence regarding the surveillance and diagnosis of HCC, focusing on recent articles and the recommendations of the American Association for the Study of Liver Diseases (AASLD), which are briefly compared with the recommendations of other liver disease organizations. HCC surveillance aims to detect disease at an early stage in order to augment the likelihood of curative treatment. According to AASLD recommendations, patients who have cirrhosis and those who do not have cirrhosis but are at high risk for HCC should be screened. Ultrasonogra-phy (USG) at 6-month intervals is recommended. The available serologic markers, including serum alpha-fetoprotein, are inadequate for surveillance, even when combined with USG. Despite achievements in HCC management, physicians continue to underutilize surveillance. Quadruple-phase, contrast-enhanced computed tomography scans or magnetic resonance images with characteristic radiologic findings are commonly used to diagnose HCC in suspicious cases. The available surveillance and diagnostic tests effectively identify HCC at an early stage, and as a result, the chances of cure are increased. Physicians caring for patients who have cirrhosis and chronic liver disease should be familiar with HCC surveillance recommendations and the prognostic importance of early diagnosis.
