The use of ace inhibitors influences the risk of progression of BD-IPMNs under follow-up

• BACKGROUND: Chemoprevention's ability to slow down or prevent the progression of BD-IPMNs is extremely appealing. Aspirin (ASA), Ace Inhibitors/Angiotensin Receptor Blockers (ACEIs/ARBs) and Statins (STATs) are frequently prescribed drugs with a possible beneficial effect on different cancer types. Their effect on IPMNs is largely unknown.AIM: To evaluate the association between the use of ASA, ACEIs/ARBs and STATs and the risk of progression of BD-IPMNs in follow-up.MATERIALS AND METHODS: multicenter, retrospective cohort study on patients with presumed BD-IPMNs without relative or absolute indication for surgery. Pharmacological exposures and risk factors were collected. We identified clinically relevant progression (occurrence of radiological absolute or relative indication for surgery) and any progression (occurrence of clinically relevant progression OR any dimension increase OR the occurrence of new cysts).RESULTS: Overall 594 patients were included. ACEIs were associated with a lower occurrence of any progression (HR = 0.70; 95% CI 0.49-0.98, p = 0.04) and clinically relevant progression, HR = 0.42 (95% CI 0.20-0.88; p = 0.02). No significant effect was shown for factors associated with the occurrence of pancreas cancer such as smoking, alcohol consumption and 1st degree family history of pancreas cancer. Among pharmacological exposures, no convincing effect was shown for the chronic use of ASA, ARB and STAT.CONCLUSIONS: ACEIs might have an effect in slowing the progression of BD-IPMNs. ASA, STAT and ARBs show no convincing effect on the progression of BD-IPMNs. Further, prospective, and long-term multicenter studies are needed to verify such association and to define the potential underlying mechanisms.
