ABSTRACT
PURPOSE:
Both ß1- and ß2-adrenoceptor proteins were detected on the cell surface of pancreatic ductal adenocarcinoma. The current study evaluated the association between beta-blocker use and pancreatic cancer risk.METHODS:
We conducted a nested case-control study in a large population representative database. Each pancreatic cancer case was matched with four controls based on age, sex, practice site, and duration of follow-up using incidence density sampling. Beta-blocker use was defined as any prescription prior to index date and was stratified into non-selective and selective ß1 -blockers. The odds ratios (ORs) and 95% confidence intervals (95% CIs) for pancreatic cancer risk associated with beta-blocker use was estimated using conditional logistic regression.RESULTS:
The study included 4113 patients with pancreatic cancer and 16 072 matched controls. When compared to never users, there was no association between any beta-blocker use and pancreatic cancer risk (adjusted OR 1.06, 95% CI 0.97-1.16, P = .16). Analysis by receptor selectivity showed use of non-selective beta-blockers for more than 2 years was associated with a reduced pancreatic cancer risk (OR 0.75, 95% CI 0.57-1.00, P = .05). When compared to former users both users of selective ß1-blockers and non-selective beta-blockers had a reduced pancreatic cancer risk (OR 0.78, 95% CI 0.67-0.90, P = .001) and (OR 0.67, 95% CI 0.49-0.92, P = .01), respectively.CONCLUSION:
Beta-blocker use was not associated with increased pancreatic cancer risk. However, long-term use of beta-blockers may be associated with decreased pancreatic cancer risk.Palavras-chave
