AB Dyslipidemia and statin use have been associated with colorectal cancer (CRC), but prospective studieshave shown mixed results. We aimed to determine whether dyslipidemia is causally linked to CRC riskusing a Mendelian randomization approach and to explore the association of statins with CRC. A casecontrolstudy was performed including 1336 CRC cases and 2744 controls (MCC-Spain). Subjects wereadministered an epidemiological questionnaire and were genotyped with an array which includedpolymorphisms associated with blood lipids levels, selected to avoid pleiotropy. Four genetic lipidscores specific for triglycerides (TG), high density lipoprotein cholesterol (HDL), low density lipoproteincholesterol (LDL), or total cholesterol (TC) were created as the count of risk alleles. The genetic lipidscores were not associated with CRC. The ORs per 10 risk alleles, were for TG 0.91 (95%CI: 0.72–1.16,p = 0.44), for HDL 1.14 (95%CI: 0.95–1.37, p = 0.16), for LDL 0.97 (95%CI: 0.81–1.16, p = 0.73), and forTC 0.98 (95%CI: 0.84–1.17, p = 0.88). The LDL and TC genetic risk scores were associated with statinuse, but not the HDL or TG. Statin use, overall, was a non-significant protective factor for CRC (OR0.84; 95%CI: 0.70–1.01, p = 0.060), but lipophilic statins were associated with a CRC risk reduction (OR 0.78; 95%CI 0.66–0.96, p = 0.018). Using the Mendelian randomization approach, our study does notsupport the hypothesis that lipid levels are associated with the risk of CRC. This study does not rule out,however, a possible protective effect of statins in CRC by a mechanism unrelated to lipid levels.
