Primary liver cancer represents the 4th most common tumor in males (4% of all cancers) and the 7th most common tumor in females (2.3% of all cancers), with a prevalence of 53/100,000 in males and 22/100,000 in females (male-to-female ratio = 2:1). In the majority of the cases, hepatocellular carcinoma (HCC) develops in patients with cirrhosis and thus the risk factors for HCC and chronic liver disease are overlapping. Viral infections (hepatitis B virus, hepatitis C virus), alcohol and fat (nonalcoholic fatty liver disease/non-alcoholic steatohepatitis) represent the main risk factors for development of HCC on cirrhotic liver. Several prospective studies reported that at present HCC does represent the first cause of death of cirrhotic patients, while in the past morbidity and mortality in cirrhosis were mainly determined by other non-neoplastic complications of the disease. From a clinical point of view, staging systems in HCC should define outcome prediction and treatment assignment. Due to the nature of HCC, the main prognostic variables are the tumor stage, liver function and performance status. The most accepted clinical classification of HCC has been proposed by the Barcelona Clinic Liver Cancer. The BCLC staging system has come to be widely accepted in clinical practice and is also being used for many clinical trials of new drugs to treat HCC. Therefore, it has become thede facto staging system that is used.

AIM: To define NGF (nerve growth factor) and its high- affinity receptor trkANGF presence and distribution in fibrotic liver and in HCC, and to verify if NGF might have a role in fibrosis and HCC. METHODS: Intracellular distribution of NGF and trkANGF were assessed by immunohistochemistry and immuno- electron microscopy in liver specimens from HCC, cirrhosis or both. ELISA was used to measure circulating NGF levels. RESULTS: NGF and trkANGF were highly expressed in HCC tissue, mainly localized in hepatocytes, endothelial and some Kupffer cells. In the cirrhotic part of the liver they were also markedly expressed in bile ducts epithelial and spindle-shaped cells. Surprisingly, in cirrhotic tissue from patients without HCC, both NGF and trkANGF were negative. NGF serum levels in cirrhotic and/or HCC patient were up to 25-fold higher than in controls. CONCLUSION: NGF was only detected in liver tissue with HCC present. Intracellular distribution suggests paracrine and autocrine mechanisms of action. Better definition of mechanisms may allow for therapeutic and diagnostic/prognostic use of NGF.
