Abstract:
Objective To explore the value of arginase-1(Arg-1) and glypican-3 (GPC-3) combined examination in the differential diagnosis of hepatocellular carcinoma (HCC),metastatic carcinoma (MC) of liver and intrahepatic cholangiocarcinoma (ICC).Methods From January 2005 to December 2011,a total of 54 patients with HCC were selected,including 10 cases with high differentiation,25 cases with moderate differentiation and 19 cases with poor differentiation.At the same time,25 patients with MC of liver and 20 patients with ICC were selected.A total of 31 normal liver specimens were set as control.The expressions of Arg 1 and GPC-3 in the above tissues were detected by immunohistochemistry method.The sensitivity and specificity of the examination in the diagnosis of HCC were analyzed.Chi-square test was performed for count data analysis.Results The positive expression rate of Arg-1 in HCC,MC of liver,ICC and normal liver tissues was 87.0％ (47/54),4.0％ (1/25),5.0％ (1/20) and 100.0％ (31/31),respectively.The Arg 1 positive expression rate in HCC tissues was higher than that in other tumor tissues of non-HCC,and the difference was statistically significant (x2 =66.98,P＜0.05).The positive expression rate of GPC-3 in HCC,MC of liver,ICC and normal liver tissues was 70.4％ (38/54),12.0％ (3/25),5.0％ (1/20) and 0 (0/31),respectively.The GPC-3 positive expression rate in HCC tissues was higher than that in other tumor tissues of non-HCC and the difference was statistically significant (x2=37.98,P＜0.05).The sensitivity and specificity of Arg-1 or GPC-3 positive in HCC diagnosis was 92.6％ (50/54) and 86.7％ (39/45).The sensitivity and specificity of both Arg 1 and GPC-3 positive in HCCdiagnosis was 64.8％ (35/54) and 100.0％ (45/45).Conclusion Arginase-1 and glypican-3 combined examination has an important value in HCC diagnosis and differential diagnosis.
