Title: Evaluation of Diagnostic and Differential Diagnostic Significance of a Combination of PIVKA-II and Other Tumor Markers in Hepatocellular Carcinoma
Brief Summary: The incidence of Hepatocellular carcinoma (HCC) is increasing worldwide. However, most of HCC cases were at advanced stage when the diagnosis established.Early diagnosis improves the prognosis.The study is intended to evaluate the diagnostic efficiency of Protein Induced by Vitamin K Absence or antagonist-II(PIVKA-II). This study is a international multicenter study joined by several hospitals in China,Singapore,Thailand and Vietnam. Participants including healthy control,HCC,metastatic liver cancer,Hepatitis B virus(HBV) and liver cirrhosis are consecutively recruited into the cohort. All the serum samples are collected before any treatments and will be tested in single center in order to decrease bias. Serum samples were tested for PIVKA-II,alpha-fetoprotein and biochemical indexes including alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyl transferase(GGT),alpha-l-fucosidase(AFU),etc.
