RESUMO
OBJECTIVE: To investigate the value of combined tests of serum Golgi protein-73, alpha-fetoprotein- L3 and Tat-interacting protein-30 in the diagnosis of hepatitis B virus related cirrhosis and hepatocellular carcinoma. METHODS: The cross-sectional study was conducted at Yuebei People's Hospital, Guangdong, China, from January to October 2017, and comprised hepatitis B patients and healthy controls. Serum Golgi protein-73, alpha-fetoprotein-L3 and Tat-interacting protein-30 levels in both groups were detected by enzyme-linked immunosorbent assay (ELISA). Alpha-fetoprotein-L3 was separated and quantified by electrochemiluminescence immunoas says and the percentage of alpha-fetoprotein-L3 to alphafetoprotein was calculated. RESULTS: Of the 721 subjects, 525(%) were patients and 196(%) were healthy controls. Among the patients, 271(%) had chronic hepatitis B, 161(%) had liver cirrhosis and 93(%) had hepatocellular carcinoma. Serum Golgi protein-73, alpha-fetoprotein-L3 and Tat-interacting protein-30 levels were significantly different in the hepatocellular carcinoma patients compared to controls, and those with chronic hepatitis and liver cirrhosis (p<0.01 each). The sensitivity and specificity of the combined detection of the three serum levels for diagnosing cirrhosis were 78.26% and 86.72%. The corresponding values for diagnosing hepatocellular carcinoma were 86.02% and 92.51%. CONCLUSIONS: Combined detection of Golgi protein-73, alpha fetoprotein-L3 and Tat-interacting protein was found to have the potential to improve diagnostic accuracy.
