Abstract
The correlation between the mass-forming type of intrahepatic cholangiocarcinoma (ICC) and the infection of the hepatitis B virus and hepatitis C virus are poorly understood. In this study, the clinical features of 34 patients with the mass-forming type ICC were reviewed to evaluate prognostic determinants. Between January 1997 and December 2007, 34 patients underwent surgical resection for the mass-forming type of ICC in Kumamoto University Hospital. The significance of 14 clinicopathological factors consisting of age, gender, CA19-9 levels, CEA levels, size, intrahepatic metastases, portal vein invasion, bile duct invasion, histological differentiation, lymph node involvement, type B or C hepatitis, lymph node dissection, Sirius Red score of the tumor and platelet count in peripheral blood were analyzed, with regard to prognostic aspect. Univariate analysis showed that significant risk factors for poor survival included age =65 years, CEA levels =1.6ng/mL and pathological lymph node involvement. Multivariate analysis revealed that age, CEA levels and lymph node involvement were independent and significant poor prognostic factors. It was concluded that age, CEA levels and lymph node involvement were significantly poor prognostic factors. However, the infection with type B or C hepatitis was not a prognostic factor of the mass forming type ICC.
