Summary |
Background and objective |
The pathogenesis and development of intrahepatic cholangiocarcinoma (ICC) may be triggered by hepatitis B virus (HBV). We conducted this retrospective study to explore the potential association between HBV infection and the clinical features and survival rate of patients with ICC.
Methods |
Patients with ICC who had undergone a curative resection were enrolled and divided into three groups according to the seropositivity of the hepatitis B surface antigen (HBsAg) and the hepatitis B core antibody (anti-HBc). The groups were as follows: group I, HBsAg (+)/anti-HBc (+); group II, HBsAg (−)/anti-HBc (+); group III HBsAg (−)/anti-HBc (−). The symptoms, pathologic findings, and outcome information of all patients were retrospectively reviewed. The patient sera were isolated to detect anti-HCV, HBsAg, and anti-HBc. Surgical specimens were assessed by hematoxylin and eosin (HE) staining. The expression of cytokeratin 7 was evaluated by immunohistochemistry. Finally, the 1-, 3-, and 5-year cumulative survival rates were analyzed.
Results |
Ninety-seven patients with ICC were enrolled in group I (n=26); group II, (n=50), and group III (n=21). A total of 26.8% (26/97) patients with ICC were positive for HBsAg. Patients with HBV-associated ICC tended to be younger (P=0.018), have lower CA19-9 levels (P=0.000), a higher alpha fetal protein (AFP) level (P=0.012) and prothrombin time (P=0.030), a higher risk of hepatic cirrhosis (P=0.001), and poor differentiation (P=0.028). The 1-, 3-, and 5-year cumulative survival rates for patients within the three groups were as follows: 27.3%, 0%, and 0% for group I, respectively; 62.5%, 30.0%, and 0% for group II, respectively; and 87.5%, 66.7%, and 50.0% for group III, respectively. The results were significantly different in an overall comparison (P=0.000).
Conclusion |
Patients with HBV-associated ICC showed different clinicopathological features and lower survival rates compared to patients with ICC without HBV infection.
