Background: Serum AFP levels are typically elevated in less than 50% of hepatocellular cancer (HCC) patients. Gamma-glutamyl transpeptidase (GGT) levels have been suggested to be a potentially useful HCC biomarker. Aims: To assess in a cohort of prospectively evaluated HCC patients who underwent liver transplant and whose survival was known; the occurrence, prognosis, and clinical characteristics of patients with elevated serum GGT levels. Results: Serum GGT levels were found to be elevated in a higher proportion in patients with either small or large HCC than alpha-fetoprotein (AFP) levels, and were significantly related to prognosis in patients with large size HCCs. There was no clear correlation between GGT and AFP levels, likely reflecting different HCC characteristics or HCC cell lineages associated with these two markers. Furthermore, elevated GGT was found in 24% of low-AFP patients with small tumors and 46% with large tumors. Elevated GGT levels were also significantly associated with microvascular invasion and tumor diameter. Conclusions: Elevated serum GGT levels were associated with HCC size and worse survival, and were unrelated to AFP levels. GGT may be a useful prognostic tumor marker, especially for low-AFP HCC patients.
The aim of the study was to report the detailed surgical techniques of living donor liver transplantation (LDLT) in patients with Budd–Chiari syndrome (BCS). Demographic and surgical techniques characteristics of 39 patients with BCS who underwent LDLT were retrospectively reviewed. Thirty-two of them had native vena cava inferior (VCI) preservation and 6 had retrohepatic VCI resection with venous continuity established by cryopreserved VCI (n = 4) or aortic graft (n = 2). In 1 patient, the anastomosis was established between the graft hepatic vein (HV) and the suprahepatic VCI. For preservation of the native VCI, immediately before the graft implantation, the thickened anterior, and right/left lateral walls of the recipient VCI were resected caudally and cranially until the intact vein wall was reached, and then an anastomosis was created between the (HV) of the graft reconstructed as a circumferential fence and the reconstructed recipient VCI. For resection of the retrohepatic VCI, the anastomosis was created with the same technique in all 6 patients in whom VCI was reformed by using a vascular graft. Post-LT complications developed in 19 of the patients. Complications related to the biliary anastomosis accounted for 12 of these cases, with 11 treated by PTC and/or ERCP, and 1 by hepaticojejunostomy. Two of the 39 patients developed recurrent BCS and were treated by interventional radiological methods. Thirteen patients died and none were related to the BCS recurrence. Favorable outcomes are achievable with LDLT treatment of patients with BCS, which carries important implications for countries with inadequate cadaveric donor pools.
