1High-dose hepatitis B immunoglobulin therapy in hepatocellular carcinoma with hepatitis B virus-DNA/hepatitis B e antigen-positive patients after living donor liver transplantation显示文摘AIM: To investigate the impact of high-dose hepatitis B immunoglobulin(HBIG) on hepatocellular carcinoma(HCC) and hepatitis B virus(HBV) recurrence and overall survival after living donor liver transplantation(LDLT).METHODS: We investigated 168 patients who underwent LDLT due to HCC, and who were HBV-DNA/hepatitis B e antigen(HBe Ag)-positive, from January 2008 to December 2013. After assessing whether the patients met the Milan criteria, they were assigned to the low-dose HBIG group and high-dose HBIG group. Using the propensity score 1:1 matching method, 38 and 18 pairs were defined as adhering to and not adhering to the Milan criteria. For each pair, HCC recurrence, HBV recurrence and overall survival were analyzed by the Kaplan-Meier method and the log rank test according to the HBIG dose. RESULTS: Among those who met the Milan criteria, the 6-mo, 1-year, and 3-year HCC recurrence-free survival rates were 88.9%, 83.2%, and 83.2% in the low-dose HBIG group and 97.2%, 97.2%, and 97.2% in the high-dose HBIG group, respectively(P = 0.042).In contrast, among those who did not meet the Milan criteria, HCC recurrence did not differ according to the HBIG dose(P = 0.937). Moreover, HBV recurrence and overall survival did not differ according to the HBIG dose among those who met(P = 0.317 and 0.190, respectively) and did not meet(P = 0.350 and 0.987, respectively) the Milan criteria. CONCLUSION: High-dose HBIG therapy can reduce HCC recurrence in HBV-DNA/HBe Ag-positive patients after LDLT.Eung Chang Lee Seong Hoon Kim Seung Duk Lee Hyeongmin Park Soon-Ae Lee Sang-Jae Park 2016World Journal of Gastroenterology2016,22,14:7
2Contribution of alpha-fetoprotein in liver transplantation for hepatocellular carcinoma显示文摘Alpha-fetoprotein(AFP) is the main tumor biomarker available for the management of hepatocellular carcinoma(HCC). Although it is neither a good screening test nor an accurate diagnostic tool for HCC, it seems to be a possible prognostic marker. However, its contribution in liver transplantation for HCC has not been fully determined, although its use to predict recurrence after liver transplantation has been underlined by international societies. In an era of organ shortages, it could also have a key role in the selection of patients eligible for liver transplantation. Yet unanswered questions remain. First, the cut-off value of serum AFP above which liver transplantation should not be performed is still a subject of debate. We show that a concentration of 1000 ng/m L could be an exclusion criterion, whereas values of < 15 ng/m L indicate patients with an excellent prognosis whatever the size and number of tumors. Monitoring the dynamics of AFP could also prove useful. However, evidence is lacking regarding the values that should be used. Today, the real input of AFP seems to be its integration into new criteria to select patients eligible for a liver transplantation. These recent tools have associated AFP values with morphological criteria, thus refining pre-existing criteria, such as Milan, University of California, San Francisco, or 'up-to-seven'. We provide a review of the different criteria submitted within the past years. Finally, AFP can be used to monitor recurrence after transplantation, although there is little evidence to support this claim. Future challenges will be to draft new international guidelines to implement the use of AFP as a selection tool, and to determine a clear cut-off value above which liver transplantation should not be performed.Bérénice Charrière Charlotte Maulat Bertrand Suc Fabrice Muscari 2016World Journal of Hepatology2016,8,21:3
