N Engl J Med. 2008 Sep 2; Authors: Peto R, Emberson J, Landray M, Baigent C, Collins R, Clare R, Califf R BACKGROUND: Five years of statin therapy lowers low-density lipoprotein (LDL) cholesterol substantially and, over a 5-year period, results in reductions in the incidence of cardiovascular events. The Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) trial (ClinicalTrials.gov number, NCT00092677) has raised the hypothesis that adding ezetimibe to statin therapy for larger LDL cholesterol reductions might increase the incidence of cancer. METHODS: We compared the results of a hypothesis-generating analysis of the incidence of cancer in the SEAS trial of ezetimibe plus simvastatin in 1873 patients (mean follow-up after ezetimibe or matching placebo was begun, 4.1 years) with a hypothesis-testing analysis of cancer data from the two large ongoing trials of this regimen: the Study of Heart and Renal Protection (SHARP) (NCT00125593) with 9264 patients (mean follow-up, 2.7 years) and the Improved Reduction of Outcomes: Vytorin Efficacy International Trial (IMPROVE-IT) (NCT00202878), currently with 11,353 patients (mean follow-up, 1.0 year). RESULTS: In the SEAS trial, assignment to ezetimibe was associated with an increase in any new onset of cancer (101 patients in the active-treatment group vs. 65 in the control group) from several cancer sites. In SHARP and IMPROVE- ...
