This systematic review was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of the PubMed database was performed for studies published up to March 2024. The inclusion criteria required the use of epigenetic studies in healthy populations exposed to carcinogenic agents or occupational exposures with sufficient evidence for bladder cancer, as classified by the International Agency for Research on Cancer, and was limited to articles written in English. We identified 23 studies examining epigenetic changes in healthy individuals exposed to 16 carcinogens or occupational exposures with established evidence of increased bladder cancer risk. These studies particularly emphasized DNA methylation analysis. Epigenetic responses associated with these exposures have been extensively studied and characterized. Although epigenetic disorders are increasingly considered critical in cancer assessments, there remain gaps in research addressing the epigenetic effects of many potential carcinogens in the human epithelium.

ED participants experienced lower cancer risk overall (HRAdjusted = 0.70; 95% CI, 0.66-0.74; P = 8.89 × 10-31), specifically for breast cancer, prostate cancer, melanoma, and secondary cancers. Cancer-specific mortality was higher among ED participants (HRAdjusted = 1.76; 95% CI, 1.49-2.08; P = 3.62 × 10-11). Compared with non-ED participants, ED participants experienced a lower incidence of cancer but higher overall cancer-specific mortality, suggesting that subsets of ED patients may benefit from postvisit preventive interventions.</p><p><strong>Prevention relevance: </strong>This cohort analysis shows that cancer incidence over 6 years was lower among participants after an ED visit than among matched non-ED participants, whereas cancer-specific mortality was higher in the ED group (HRAdjusted = 1.76; 95% CI, 1.49-2.08; P = 3.62 × 10-11), suggesting the potential benefit of preventive interventions.</p>","PeriodicalId":72514,"journal":{"name":"Cancer prevention research (Philadelphia, Pa.)","volume":" ","pages":"413-421"},"PeriodicalIF":0.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12213139/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143796436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
