[PMID: 38200678 DOI: 10.1111/jgh.16468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 11/25/2023] [Accepted: 12/18/2023] [Indexed: 01/12/2024]
Abstract
BACKGROUND AND AIM The incidence of colorectal cancer (CRC) in individuals under 50 is increasing worldwide. We conducted an analysis of colonoscopy findings in high-risk individuals under 50 in the CRC screening program in Tianjin, China, to determine the detection rate and risk factors of advanced adenomas (AA), advanced colorectal neoplasia (ACN), colorectal neoplasia (CN). METHODS Our study investigated individuals aged 40-49 who underwent CRC screening and completed colonoscopy, 2012-2020, while the 50-54 age group served as a control. We compared the detection rates of AA, ACN, and CN among three age groups using univariate and multivariable logistic regression analyses, and investigated the risk factors associated with AA, ACN, and CN among individuals aged 40-49. RESULTS We found a gradual increase in the detection rate of AA, ACN, and CN among individuals aged 40-54. The detection rates for AA (OR 0.58; 95% CI 0.41-0.81), ACN (OR 0.58; 95% CI 0.43-0.77), and CN (OR 0.64; 95% CI 0.56-0.74) were lower in individuals aged 40-44 compared to 45-49. The detection rates of AA (OR 1.08; 95% CI 0.87-1.34) and ACN (OR 1.12; 95% CI 0.93-1.35) in individuals aged 45-49 were comparable with 50-54. Besides, lifestyle factors, BMI, and FIT are not associated with the detection rates of AA, ACN, and CN among individuals aged 40-49. CONCLUSIONS Our study reveals screening data in individuals under 50, indicating comparable detection rates of AA and ACN in individuals aged 45-49 and 50-54. These findings provide valuable data support for optimizing the optimal age to initiate screening.

Cancer Epidemiol Biomarkers Prev 2021; 30:1792-1798. [PMID: 34301728 DOI: 10.1158/1055-9965.epi-20-1127] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2020] [Revised: 02/22/2021] [Accepted: 07/07/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The incidence of early-onset colorectal cancer (eoCRC) diagnosed among individuals under age 50 has been rising. However, risk factors for eoCRC are unclear. We investigated whether metabolic abnormalities are risk factors for eoCRC adenocarcinoma. METHODS Invasive colorectal adenocarcinoma cases diagnosed between ages 15 and 49 from 2008 to 2018 at Kaiser Permanente Southern California (KPSC) were identified. Those with a history of inflammatory bowel disease were excluded. Noncancer controls were selected 5:1 for each case matched by age, sex, and length of membership prior to index date. Data were collected from KSPC's electronic medical records. The exposures of interest included obesity, type II diabetes, hypertension, and dyslipidemia, assessed from ≥1 year prior to eoCRC diagnosis/index date. Conditional logistic regressions were used to evaluate the associations between these metabolic risk factors and risk of eoCRC adenocarcinoma, adjusting for race/ethnicity, smoking, family history, neighborhood socioeconomic status, and health care utilization. RESULTS A total of 1,032 cases and 5,128 controls were included. Risk of colorectal adenocarcinoma was significantly associated with obesity [odds ratio (OR) = 1.41; 95% confidence interval (CI), 1.15-1.74], but not diabetes, hypertension or dyslipidemia. In analysis stratified by tumor location, obesity was significantly associated with risk of colon adenocarcinoma OR = 1.56 (1.17-2.07), but its association with rectal adenocarcinoma was less clear OR = 1.19 (0.85-1.68). No significant interaction was detected between obesity and age (≥40 vs. <40), and obesity and sex. CONCLUSIONS Obesity was associated with risk for eoCRC adenocarcinoma. IMPACT This finding could help inform early-onset colorectal adenocarcinoma screening and prevention recommendations.See related commentary by Hayes, p. xxx.

[PMID: 29285265 PMCID: PMC5739652 DOI: 10.18632/oncotarget.22295] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2017] [Accepted: 08/26/2017] [Indexed: 01/05/2023] Open
Abstract
Objectives This study aimed to explore the effects of vascular endothelial growth factor A (VEGFA) gene polymorphisms (rs699947 and rs833061) on Bevacizumab (BEV) treatment in colorectal cancer (CRC) patients. Methods 125 CRC cases receiving BEV plus FOLFIRI treatment were recruited in this study. VEGFA polymorphisms were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Correlation of VEGFA gene polymorphisms with the response rate and progression free survival (PFS) was evaluated. Multivariate analyses were performed to estimate the effects of VEGFA polymorphisms on the therapeutic effects of BEV treatment in CRC patients. Results Rs699947 variants did not show significant association with BEV treatment. For rs833061 analysis, TT and TC genotype carriers had significantly higher ORR (objective response rate) than CC carriers (P=0.048 and P=0.021, respectively). Moreover, TT carriers underwent a well DCR (disease control rate) compared to CC carriers (P=0.002). PFS time also showed obvious correlation with rs833061 polymorphism (log rank test, P=0.002). Multivariate analyses demonstrated that TT and TC genotypes of rs833061 polymorphism were significantly correlated with enhanced therapeutic effects and prolonged PFS in CRC patients. Conclusion VEGFA rs833061 polymorphism is significantly associated with the therapeutic efficiency of bevacizumab in CRC patients.
