title: Combined Evaluation of AFP, CA15-3, CA125, CA19-9, and CEA Tumor Markers in Patients with Hepatitis B and C.
abstract: BACKGROUND
  This study aimed to determine the role of tumor markers AFP, CA15-3, CA125, CA19-9 and CEA in patients with hepatitis B and C.
  
  
  METHODS
  This descriptive cross-sectional study was performed from Oct 2012 to Oct 2014. Serum samples of 129 patients with hepatitis B and C referred to Guilan Liver and Digestive Disease Research Center in Rasht, Iran were collected and checked for the existence of the listed tumor markers by ELISA.
  
  
  RESULTS
  No increase in serum levels of tumor marker CA19-9, CEA and CA15-3 were seen in patients with hepatitis (P>0.05). In patients with hepatitis B, increase in CA125 were observed (P=0.03). In hepatitis C patients, there was an increase in AFP levels (P=0.03).
  
  
  CONCLUSIONS
  The levels of AFP and CA125 markers were high in hepatitis C and hepatitis B, respectively. However, the increased levels were not seen is malignancy. Due to the small sample size, further study is necessary to find the reasons of the increase.
