title: [Hepatita B and C virus infections in patients with hepatocellular carcinoma].
abstract: BACKGROUND
  The prevalence of HBV and HCV infections in patients with hepatocellular carcinoma may be related to variations in the geographic area of study. For this reason, we have analized the relative prevalence of HBV and HCV infections in 94 patients with hepatocellular carcinoma from Cantabria (North of Spain).
  
  
  METHODS
  We have studied 94 patients with hepatocellular carcinoma from January 1988 to December 1993. Commercially available radioimmunoassay or ELISA were used for detection of HBsAg, anti-HBs and anti-HBc. The HBV DNA was analized by PCR. The HCV infection was assayed by ELISA-2 and RT-PCR.
  
  
  RESULTS
  The HBV infection was detected in 27 patients: 19 patients were HBsAg positive and 8 patients HBsAg negative, anti-HBc positive, DNA HBV positive by PCR. The HCV infection was found in 57 patients. Forty patients were infected with both viruses. Of the remain twenty-four, forty were alcoholics. We found in 61 patients more than one etiological factor. Hepatoma was the first manifestation of liver disease in 24 cases and these were more frequently in HCV than in those with HBV infection. Moreover, the first group were older and have lower alcohol intake.
  
  
  CONCLUSIONS
  1) In Cantabria, Spain, the majority of cases of hepatocellular carcinoma are related to HBV, HCV and alcohol. 2) Analysis of DNA HBV and RNA HCV by PCR allows the diagnosis of cryptic infections by both viruses, especially in the cases of HBV and HCV coinfection. 3) Hepatoma is the first manifestation of liver disease in a high percentage of cases.
