Given that acetaldehyde associated with alcohol consumption is assessed as a carcinogen, consideration of differences in acetaldehyde exposure would aid accuracy in assessing the bladder cancer risk associated with alcohol consumption. Here, we conducted a population\u2010based cohort study in Japan to examine this association, including information on the flushing response as a surrogate marker of the capacity of acetaldehyde metabolism. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated using multivariate Cox proportional hazard models. During follow up from 1990 through 2012 for the 95,915 subjects (45,649 men and 50,266 women, aged 40\u201369 years), 354 men and 110 women were newly diagnosed with bladder cancer. No significant association between alcohol consumption and bladder cancer risk was observed in the overall analysis. Among male flushers, HRs were 1.04 (95% CI 0.70\u20131.54), 1.67 (1.16\u20132.42), 1.02 (0.62\u20131.67) and 0.63 (0.33\u20131.20) for alcohol consumption of 1\u2013150, 151\u2013300, 301\u2013450, &gt;450 g\/week of pure ethanol compared with non\u2010drinkers and occasional drinkers, respectively, indicating an inverted U\u2010shaped association between alcohol consumption and bladder cancer risk. In contrast, no significant association was identified among male non\u2010flushers. The marginally significant interaction between alcohol consumption and the flushing response (<jats:italic>p<\/jats:italic> for interaction\u2009=\u20090.083) may support our hypothesis that acetaldehyde derived from alcohol consumption is associated with bladder cancer risk. A prospective study considering polymorphisms of genes involved in acetaldehyde metabolism is warranted.<\/jats:p>","DOI":"10.1002\/ijc.31028","type":"journal-article","created":{"date-parts":[[2017,9,6]],"date-time":"2017-09-06T01:13:29Z","timestamp":1504660409000},"page":"2480-2488","source":"Crossref","is-referenced-by-count":17,"title":["Alcohol consumption and bladder cancer risk with or without the flushing response: The Japan Public Health Center\u2010based Prospective Study"],"prefix":"10.1002","volume":"141","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1990-5937","authenticated-orcid":false,"given":"Hiroyuki","family":"Masaoka","sequence":"first","affiliation":[{"name":"Division of Molecular and Clinical Epidemiology Aichi Cancer Center Research Institute Nagoya Japan"},{"name":"Department of Urology Graduate School of Medical Sciences, Kyushu University Fukuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1761-6314","authenticated-orcid":false,"given":"Keitaro","family":"Matsuo","sequence":"additional","affiliation":[{"name":"Division of Molecular and Clinical Epidemiology Aichi Cancer Center Research Institute Nagoya Japan"},{"name":"Department of Epidemiology Nagoya University Graduate School of Medicine Nagoya Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norie","family":"Sawada","sequence":"additional","affiliation":[{"name":"Epidemiology and Prevention Group, Research Center for Cancer Prevention and Screening National Cancer Center Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taiki","family":"Yamaji","sequence":"additional","affiliation":[{"name":"Epidemiology and Prevention Group, Research Center for Cancer Prevention and Screening National Cancer Center Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsushi","family":"Goto","sequence":"additional","affiliation":[{"name":"Epidemiology and Prevention Group, Research Center for Cancer Prevention and Screening National Cancer Center Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Taichi","family":"Shimazu","sequence":"additional","affiliation":[{"name":"Epidemiology and Prevention Group, Research Center for Cancer Prevention and Screening National Cancer Center Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Motoki","family":"Iwasaki","sequence":"additional","affiliation":[{"name":"Epidemiology and Prevention Group, Research Center for Cancer Prevention and Screening National Cancer Center Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manami","family":"Inoue","sequence":"additional","affiliation":[{"name":"Epidemiology and Prevention Group, Research Center for Cancer Prevention and Screening National Cancer Center Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masatoshi","family":"Eto","sequence":"additional","affiliation":[{"name":"Department of Urology Graduate School of Medical Sciences, Kyushu University Fukuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shoichiro","family":"Tsugane","sequence":"additional","affiliation":[{"name":"Epidemiology and Prevention Group, Research Center for Cancer Prevention and Screening National Cancer Center Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"name":"for the Japan Public Health Center\u2010based Prospective Study Group","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,9,15]]},"reference":[{"key":"e_1_2_7_2_1","unstructured":"FerlayJ SoerjomataramI ErvikM et al.
