Observational studies suggested that sensitivity of fecal immunochemical tests for detecting advanced neoplasms could be increased by acetylsalicylic acid (aspirin), especially among men.To evaluate the potential to increase sensitivity of fecal immunochemical tests by administering a single 300-mg oral aspirin dose 2 days before stool sampling.A randomized, placebo-controlled, double-blind trial was conducted in 14 gastroenterology practices and 4 hospitals in Germany, and included 2422 men and women aged 40 to 80 years scheduled for colonoscopy, with no recent use of aspirin or other drugs with antithrombotic effects (enrollment from June 2013 to November 2016, and final follow-up January 27, 2017).Administration of a single tablet containing 300 mg of aspirin (n = 1208) or placebo (n = 1214) 2 days before fecal sampling for fecal immunochemical test.The primary outcome was sensitivity of a quantitative fecal immunochemical test at 2 predefined cutoffs (10.2 and 17-μg Hb/g stool) for detecting advanced neoplasms (colorectal cancer or advanced adenoma).Among 2422 randomized patients (mean [SD] age, 59.6 [7.9] years; 1219, $50\%,$ men), 2134 were included in the analysis $(78\%$ for primary screening colonoscopy, $22\%$ for diagnostic colonoscopy). Advanced neoplasms were identified in 224 participants $(10.5\%),$ including 8 participants $(0.4\%)$ with CRC and 216 participants $(10.1\%)$ with advanced adenoma. Sensitivity was $40.2\%$ in the aspirin group and $30.4\%$ in the placebo group (difference $9.8\%,$ $95\%$ CI, $-3.1\%$ to $22.2\%,$ P = .14) at cutoff 10.2-μg Hb/g stool and $28.6\%$ in the aspirin and $22.5\%$ in the placebo group (difference $6.0\%,$ $95\%$ CI, $-5.7\%$ to $17.5\%,$ P = .32) at cutoff 17-μg Hb/g stool.Among adults aged 40 to 80 years not using aspirin or other antithrombotic medications, administration of a single dose of oral aspirin prior to fecal immunochemical testing, compared with placebo, did not significantly increase test sensitivity for detecting advanced colorectal neoplasms at 2 predefined cutoffs of a quantitative fecal immunochemical test.Deutsches Register Klinischer Studien Identifier: DRKS00003252; EudraCT Identifier: 2011-005603-32/DE.}, cin = {C070 / C120 / C060 / L101}, ddc = {610}, cid = {I:(DE-He78)C070-20160331 / I:(DE-He78)C120-20160331 / I:(DE-He78)C060-20160331 / I:(DE-He78)L101-20160331}, pnm = {313 - Cancer risk factors and prevention (POF3-313)}, pid = {G:(DE-HGF)POF3-313}, typ = {PUB:(DE-HGF)16}, pubmed = {pmid:31063574}, doi = {10.1001/jama.2019.4755}, url = {https://inrepo02.dkfz.de/record/143636}, }
