Abstract
BACKGROUND: Hepatocellular carcinoma (HCC) is the most common primary hepatic malignancy. Early detection of HCC is always a challenging task for physicians. Serum Golgi protein 73 (GP73) is considered a potential tumor marker for the detection of HCC. However, the diagnostic value of GP73 for the HCC diagnosis is still controversial. This research was designed to assess the diagnostic efficacy of GP73 as a diagnostic tool for HCC in cases with hepatitis C virus-related cirrhosis. METHODS: Eighty-seven subjects were allocated into four different groups in this prospective research (HCC, liver cirrhosis, chronic hepatitis C, and healthy control group). Serum alpha-fetoprotein (AFP) and GP73 were tested for all subjects in the study. Detection of focal hepatic lesions was based on imaging by abdominal ultrasonography and triphasic computed tomography. RESULTS: The cut-off values for GP73 and AFP were 534.5 ng/L and 32 ng/mL, respectively. The specificity of GP73 was 87%, and the sensitivity was 88%, while the specificity and sensitivity of AFP levels were 80% and 72%, respectively. The negative predictive value of GP73 was 87.5%, and the positive predictive value of GP73 was 84.6%, while the same parameters of AFP were 73.1% and 75%, respectively. CONCLUSION: Serum Golgi protein 73 could be a valuable biomarker and a useful diagnostic tool for the early diagnosis of HCC in cases of hepatitis C virus-related cirrhosis.
