Diagnostic Value of AFP-L3 and PIVKA-II in HCC

March 2, 2018 updated by: Bui My Hanh, Hanoi Medical University
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 alpha-fetoprotein-L3 (AFP-L3) and Protein Induced by Vitamin K Absence or antagonist-II (PIVKA-II). This study is performed at Hanoi Medical University Hospital. Participants including patients with HCC and hepatic hemangioma. 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, AFP, AFP-L3 and biochemical indexes including alanine aminotransferase(ALT),aspartate aminotransferase (AST), gamma-glutamyl transferase, HbsAg, Anti HCV, etc.

Detailed Description

Hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths worldwide.Early diagnosis improves the prognosis. Protein induced by vitamin K antagonist-II (PIVKA-II), also known as des-γ-carboxyprothrombin (DCP) or acarboxy prothrombin, is an abnormal form of prothrombin induced by vitamin K absence or antagonist-II. The study is intended to evaluate the diagnostic efficiency of AFP-L3 and PIVKA-II. AFP-L3 and PIVKA-II as an effective tumor marker for hepatocellular carcinoma(HCC). Despite the extensive application of PIVKA-II in some hospitals from Vietnam, the diagnostic efficiency including sensitivity, specificity, positive predictive value and negative predictive value still needs more clinical data to evaluate. The research purposes list as follows：1. Determination of changes in AFP-L3 and PIVKA II for HCC.2. Investigating the diagnostic value of AFP-L3 and PIVKA II for HCC. This study is performed at Hanoi Medical University Hospital. Participants including patients with HCC and hepatic hemangioma. 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, AFP, AFP-L3 and biochemical indexes including alanine aminotransferase(ALT),aspartate aminotransferase (AST), gamma-glutamyl transferase, HbsAg, Anti HCV, etc.The diagnosis of HCC was based on HCC criteria of Ministry of Public Health of Vietnam. All HCC diagnoses were confirmed at the time of analysis. Stages of tumor is evaluated by Barcelana classification. The Student's t-test (or Mann-Whitney test) was used to compare continuous variables, and the chi-square test (or Fisher's exact test) was used for categorical variables. A receiver operator characteristic (ROC) curve was used to assess the performance characteristic of PIVKA-II,AFP,AFP-L3 measurement.
