ABSTRACT
Objective To analyze the expression of activated T cell nuclear factor (NFAT) in hepatoeellular carcinoma (HCC) tissues and its correlation with clinicopathological factors.Methods Data of 105 patients including 87 males and 18 females,aged 55.1 ± 10.8 years old,diagnosed with HCC who underwent hepatectomy in hepatobiliary surgery department of the first central hospital of Tianjin from September 2014 to December 2016 were retrospectively analyzed,Immunohistochemical staining was used to detect the expression of NFAT subtypes in HCC tissues and adjacent normal liver tissues,and the differences in expression of NFAT subtypes and related factors were analyzed.Results HCC tissues had higher expression of NFAT4 and lower expression of NFAT1 compared to adjacent tissues (P＜0.05).NFAT1 positive group had higher HBV infected rate (93.1％ vs.78.7％) and lower microvascular invasion rate than that in NFAT1 negative group (24.1％ vs.46.8％) (P＜ 0.05).NFAT3 positive group had more younger patients (≤ 60 years old) (80.0％ vs.60.0％) and higher microvascular invasion rate (46.2％ vs.15.0％) (P＜0.05).NFAT4 positive group had higher microvascular invasion rate (43.3％ vs.22.2％) (P＜0.05).Conclusion HCC tissues had different expressions of NFATs.The expressions of NFAT1,NFAT3 and NFAT4 are related to microvascular invasion.
ABSTRACT
Objective To compare salvage liver transplantation (SLT) with othotopic liver transplantation (OLT) in treatment of hepatocellular carcinoma.Methods A systematic literature search of PubMed,Embase,Cochrane Library,CBM,CNKI and Wanfang Med Online was performed from their dates of establishment to October 2017.The results were screened,data extracted and then analyzed with Stata 14.Results 23 studies with 4 161 patients were selected,including 579 patients in the SLT group and 3 582 patients in the OLT group.Compared with OLT,SLT was associated with a longer operative time (SMD =0.56,95％CI:0.29～0.83),higher intraoperative blood loss (SMD=1.56,95％CI:0.63～2.49),an increased risk of postoperative bleeding (OR =1.84,95％CI:1.08 ～ 3.14),a poorer overal survival rate (HR =1.29;95％CI:1.11～1.49) and disease free survival rate (HR=1.88;95％CI:1.26～2.81).The differences were all significant (all P＜0.05).The biliary complications (OR=1.25;95％CI:0.79～1.98),vascular complications (OR=1.41;95％CI:0.69～2.89),sepsis (OR=1.10;95％CI:0.60～ 1.99),acute rejection (OR =1.25;95％ CI:0.69 ～ 2.28) and perioperative mortality (OR =1.60;95 ％ CI:0.94 ～ 2.70) rates were not significantly different (all P＞0.05).Conclusions OLT is a better treatment strategy for patients with transplantable hepatocellular carcinoma (HCC) compared with SLT.However,severe organ limitation,and feasibility and safety of surgery make SLT a better option for patients with HCC recurrence after liver resection.
