Background/Aims An association between past history of hepatitis B virus (HBV) infection and pancreatic cancer (PC) has recently been reported. We investigated whether HBV and hepatitis C virus (HCV) infections are associated with the development of PC in Korea. Methods: We retrospectively recruited patients with PC and sex-and, age-matched control patients with stomach cancer (SC) during the previous 5 years. Serum HBsAg and anti-HCV were examined, and data on smoking, alcohol intake, diabetes, and the history of chronic pancreatitis (CP) were collected. Results: A total of 506 PC and 1008 SC were enrolled, with respectively 58.1% and 97.3% of these cases being confirmed histologically. The mean age and sex ratio male:female) were 63.5 years and 1.5:1 in the PC patients and 63.9 years and 1.5:1 in the SC patients respectively (P>0.05). The odds ratios (95% confidence interval, 95% CI) in univariate analysis were 0.90 0.52-1.56; P=0.70) for HBsAg, 1.87 (0.87-4.01; P=0.11) for anti-HCV, 2.66 (2.04-3.48; P<0.001) for the presence of diabetes, 2.30 (1.83-2.90; P<0.001) for smoking, 1.14 (0.89-1.46; P=0.31) for alcohol intake, and 4.40 1.66-11.66; P=0.003) for the history of CP. Independent risk factors for PC were presence of diabetes (OR, 2.67; 95% CI, 2.00-3.56; P<0.001), smoking (OR, 2.49; 95% CI, 1.93-3.21; P<0.001) and history of CP (OR, 4.60; 95% CI, 1.56-13.53; P=0.006). Conclusions: There was no significant association between seropositivity for HBsAg or anti-HCV and PC. Further studies are warranted to clarify the association between HBV infection and PC in regions where HBV is endemic. (Korean J Hepatol 2010;16:49-56) |
