Abstract: Objective: This study was designed to evaluate the role of serum alpha-fetoprotein-L3 subfraction (AFP-L3) and osteopontin (OPN) in the diagnosis of hepatocellular (HCC) and to consider their potential role as a novel prognostic marker. Patients and Methods: 120 patients with different stages of HCC were included in addition to 140 subjects with chronic liver diseases and 140 healthy control. Following clinical and radiological investigations, serum assay of AFP, AFP-L3 and OPN were performed.Results: AFP, AFP-L3 and OPN were significantly higher in HCC patients compared to chronic liver disease patients and normal control. A significant correlation was found between AFP and AFP-L3/AFP ratio among HCC patients. OPN varied significantly among different HCC stages. The best cutoff points revealed 100% sensitivity and 85% specificity for AFP-L3 and 100% for both sensitivity and specificity of OPN. Conclusion: Higher levels of AFP-L3 and OPN in HCC patients than controls propose them as potential markers for diagnosis of this disease. OPN has additional prognostic value through its significant difference among different HCC grades.
