Statin treatment and cancer risk

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

  • a meta-analysis and meta-aggression of 35 randomized controlled trials was undertaken to investigate whether statin treatment had a protective effect on cancer risk
  • the authors however did not find evidence to support a protective effect of statins against cancer
    • however the authors noted that this conclusion was limited by the relatively short follow-up periods (4.5 years on average) of the studies analyzed
  • a prospective open cohort study has examined and quantified the unintended risks and benefits of statins in a large representative primary care population over a six year period
    • with respect to risk of oesophageal cancer and statin treatment (2)
      • risk of oesophageal cancer decreased in both men and women associated with statin treatment
      • based on the 20% threshold for cardiovascular risk, for women the NNT with any statin to prevent one case of cardiovascular disease over five years was 37 (95% confidence interval 27 to 64) and for oesophageal cancer was 1266 (850 to 3460) and for men the respective values were 33 (24 to 57) and 1082 (711 to 2807)

  • statin use in heart failure
    • Qing-Wen et al undertook a study that suggests that statin use is associated with a significantly lower risk of incident cancer and cancer-related mortality in HF, an association that appears to be duration dependent
