Abstract: Background/Aims: No reliable serum markers for liver inflammation, apoptosis and fibrosis have been established yet, although a large number have been evaluated. Moreover, it is not clear if a molecule detected and quantified in peripheral vein blood is a really trustworthy marker of the liver condition. To answer to this question, we had the opportunity to study paired serum samples drawn simultaneously during haemodynamic study from the right hepatic vein and from a peripheral vein from patients with hepatitis C virus related cirrhosis. Methods: The serum levels of transforming growth factor beta-1, tumour necrosis factor-alpha, hyaluronic acid, soluble (s)human leukocyte class I antigens, soluble FAS ligand, and stumour necrosis factor related ligand were assessed in a consecutive series of 15 patients with hepatitis C virus related cirrhosis. Results: No statistically significant differences were found between hepatic vein and peripheral vein levels for the cytokines, substance or soluble molecules evaluated, excepted for shuman leukocyte class I antigens. Instead a strong correlation between hepatic vein and peripheral vein levels was present for: hepatic vein, shuman leukocyte class I antigens, tumour necrosis factor-alpha, soluble FAS ligand and stumour necrosis factor related ligand, but not for transforming growth factor beta-1. Conclusions: Our results show that peripheral vein measurements seem to reflect the liver compartment in a large majority of cases, but not for all molecules and probably for any liver diseases. Further studies on this line are warranted in particular for new molecules. [Copyright &y& Elsevier]

Abstract: Aim: The present study focused on nine patients with hepatocellular carcinoma (HCC) associated with Child A liver cirrhosis undergoing first-line liver resection and salvage liver transplantation (SLT) for liver tumor recurrence. Patients and methods: Forty-six patients with HCC underwent liver transplantation (OLT); 37 (80.5%) were primary liver transplantations (PLTs) and 9 (19.5%) were SLTs. All patients who underwent SLT received minor transabdominal liver resections. Results: The posttransplant 1-, 3-, and 5-year overall survival rates for SLT (88.9%, 88.9%, and 88.9%) were similar to those for PLT (78%, 62.7%, and 62.7%). Four (10.8%) patients in the PLT group had HCC recurrence, while there was zero recurrence in the SLT group. The 1-, 3-, 5-year disease-free survival rates for PLT (89%, 74%, and 74%) were similar to those for SLT (100%, 100%, and 100%). The 1-, 3-, 5-year disease-free survival rates after PLT were 89%, 74%, and 74%, and after SLT were 100%, 100%, and 100%, respectively. The operative mortality, intraperioperative bleeding, operative time, intensive care unit stay, in-hospital stay, and overall incidence of postoperative complications were similar in the two groups. Conclusions: In our experience, SLT for HCC is a feasible procedure with similar results in terms of overall survival, disease-free survival, and postoperative complications to those reported for patients who underwent PLT at our institute. An important role exists for SLT as shown by the fact that such a strategy has been used in the 20% of the patients undergoing OLT for HCC. [Copyright &y& Elsevier]
