目的
2
探讨泛素特异性蛋白酶44(USP44)在肝细胞癌(HCC)中的表达及其临床病理学意义。
方法
2
运用免疫组化方法,检测USP44蛋白在161例肝细胞癌中的表达水平,统计分析其与临床病理参数之间的相关性及其预后价值。
结果
2
在161例HCC患者中,98例(60.9%)高表达USP44蛋白,Pearson′s卡方检验结果显示USP44在HCC中的表达水平与临床分期(

结论
2
USP44蛋白高表达的HCC患者具有良好的生存期,检测其蛋白表达可作为筛选预后良好的肝细胞癌患者的一种手段。
Objective
2
To investigate the expression of Ubiquitin specific protease 44(USP44)and its clinical significance in hepatocellular carcinoma(HCC).
Methods
2
Immunohistochemistry was used to detect the expression of USP44 protein in 161 cases of hepatocellular carcinoma. The correlation between the expression of USP44 protein and clinicopathological parameters,and its prognosis value were analyzed.
Results
2
Immunohistochemical analysis showed USP44 displayed elevated expression in 98 HCC cases out of 161 cases. Pearson′s chi-square test indicated the expression of USP44 in HCC was significantly correlated with clinical stage(
χ
2
=14.44,
P
<0.001) and tumor multiplicity(Unifocal or Multifocal)(
χ
2
=8.04,
P
=0.005). Kaplan-Meier analysis indicated patients with low USP44 expression correlated with poor overall survival(Log-rank
χ
2
=20.77,
P
<0.001).The overall mean survival time was 59.6 months in low USP44 expression patients and 185.0 months in high USP44 expression patients. The Cox proportional hazard model analysis showed USP44 was an independent prognostic risk factor for HCC patients.
Conclusion
2
USP44 is an independent prognostic risk factor for HCC patients, and the expression of USP44 protein could be used to screen patients with good prognosis for HCC. Our study may provide evidence for USP44 as a potential therapeutic target for HCC patients.
