PIVKA-II Combined With Alpha-Fetoprotein for Diagnostic and Prognostic Value of Hepatic Tumors in Infants
Study Details
Study Description
Brief Summary
Although hepatic tumors are uncommon in the perinatal period they are associated with significant morbidity and mortality in affected patients. The study is intended to evaluate the diagnostic efficiency of Protein Induced by Vitamin K Absence or antagonist-II(PIVKA-II) combining with alpha-fetoprotein in hepatic tumor of infant. This study is a multicenter study joined by several hospitals in China. Participants including hepatoblastoma, hepatic hemangioendothelioma and healthy control are consecutively recruited into the cohort. All the serum samples are collected before and after each treatment 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.

Detailed Description
Hepatic tumors seldom occur in the perinatal period. They comprise approximately 5% of the total neoplasms of various types occurring in the fetus and neonate. Infantile hemangioendothelioma is the leading primary hepatic tumor followed by hepatoblastoma. Although alpha-fetoprotein has been well recognized as biomarker of hepatic tumors, it should be mentioned that this protein in normal infants is highly elevated during the first 2 months of life.
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. An elevated serum level of PIVKA-II is reported to be associated with hepatocellular (HCC). Many studies have shown that PIVKA-II is applicable for HCC surveillance and has been written into the guideline of JSH, which achieves remarkably good results.
The study is intended to evaluate diagnostic and differential diagnostic accuracy of PIVKA-II combining with alpha-fetoprotein in hepatic tumor of infant.
This study is a multicenter study joined by several hospitals in China. Participants including hepatoblastoma, hepatic hemangioendothelioma and healthy control. All the serum samples are collected before and after each treatment and will be tested in single center in order to decrease bias. Serum samples were tested for PIVKA-II, Alpha-fetoprotein(AFP)， and biochemical indexes including ALT, AST, GGT, AFU, etc. The diagnosis of hepatoblastoma and hepatic hemangioendothelioma was based on enhanced CT scanning and/or histopathology. 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 diagnostic and differential diagnostic efficiency of PIVKA-II and the combined tumor markers with AFP.
