We calculated annual percentage changes (APCs), Mortality-Incidence Ratios (MIRs), and Standardized Incidence and Mortality Ratios (SIRs, SMRs) for all cancers and specific sites.</div></div><div><h3>Results</h3><div>In 2021, Puerto Rico’s population aged 85 + was 108,041. Since 2001, cancer incidence and mortality rates for both males and females aged 85 + in Puerto Rico declined. Puerto Rico’s decline in male cancer incidence (APC = −3.1 %) and mortality (APC = −3.3 %) exceeded the respective decline in incidence (APC = −0.08 %) and mortality (APC = −0.9 %) in Hispanic/Latino male populations in the U.S. However, in 2021, the MIR in 85 + females in Puerto Rico (0.73) and males (0.94) were higher than most comparable state MIRs. While stable in most other U.S. Hispanic/Latino populations, between 2005 and 2021 in Puerto Rico, the proportion of staged cancers diagnosed at advanced stages increased 12 %.</div></div><div><h3>Conclusions</h3><div>While significant progress has been made in reducing cancer incidence and mortality among Puerto Rico’s oldest residents, challenges persist. Policies improving healthcare access could help reduce the burden of cancer incidence and mortality among Puerto Rico’s aging population. Data revealing disaggregated ethnicity and nationality beyond Hispanic/Latino could further inform targeted efforts to advance cancer equity across the U.S.</div></div>","PeriodicalId":56322,"journal":{"name":"Cancer Epidemiology","volume":"97 ","pages":"Article 102838"},"PeriodicalIF":2.4,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of microplastic exposure on colorectal adenocarcinoma development has gained attention. This systematic review aimed to summarize studies of microplastic exposure in humans with colorectal cancer. The relevant studies were collected through a computer-assisted search in PubMed, ISI Web of Science, Embase, Scopus, and Google Scholar databases. A total of 747 documents were evaluated for eligibility by two independent authors. The quality assessment of eligible studies was evaluated by the JBI checklist, and required data were collected and extracted from the included studies. After analysis, four studies were found eligible. The microplastic infiltration in colorectal tissue biopsies was relatively high; polyamide, polycarbonate, and polypropylene polymers were among the most common polymers in colorectal tissue samples of patients with colorectal adenocarcinoma. The average particle size was 0.1 µm to 1.6 mm. Microplastics shape in colorectal cancerous tissue, including fibers, fragments, and films. Microplastic abundance in colorectal tumor tissue was 25.9–32.2 particles/g tissue. In the case-control study, the microplastic accumulation in colorectal cancer tissue samples was significantly higher than in controls. The etiology of colorectal cancer remains unclear; however, environmental factors are actively contributing to colorectal cancer development. While there are few studies on microplastics in patients with colorectal adenocarcinoma, existing evidence indicates microplastic accumulation in the colorectal tissue of these patients. Further research is needed to determine if microplastic exposure initiates or leads to the development of colorectal cancer events.</div></div>","PeriodicalId":56322,"journal":{"name":"Cancer Epidemiology","volume":"97 ","pages":"Article 102840"},"PeriodicalIF":2.4,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144090228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
