Therefore, we analyzed the incidence, prevalence, survival, and risk factors for HCC in patients with PBC from two European centers (389 from Barcelona, Spain, and 327 from Padova, Italy) followed up for 9.3 \u00b1 6.5 years. Gender, age, smoking habit, alcohol consumption, presence of hepatitis B surface antigen (HBsAg) or hepatitis C virus antibodies (anti-HCV), and advanced histological stage (III-IV) were evaluated as risk factors for tumor development. Twenty-four patients (13 from Barcelona and 11 from Padova) developed HCC. The prevalence of HCC was similar in Barcelona (3.34%) and Padova (3.36%). The incidence was 0.35 and 0.37 per 100 patient-years, respectively. Male gender, age &gt;52 years, smoking habit, alcohol &gt;40 g\/day, HBsAg, and anti-HCV were not associated with HCC. Advanced histological stage was the only factor associated with the development of HCC (odds ratio [OR]: 5.80, 95% confidence interval [CI]: 2.34-14.38,<\/jats:bold>\n                      <jats:bold>P<\/jats:bold>\n                      <jats:bold>&lt; 0.001). When analyzing the two series separately, male gender was associated with higher likelihood of HCC in Padova (OR: 8.09, 95% CI: 1.93-33.8,<\/jats:bold>\n                      <jats:bold>P<\/jats:bold>\n                      <jats:bold>&lt; 0.01).
