Cancers (Basel) 2023; 15:cancers15113006. [PMID: 37296969 DOI: 10.3390/cancers15113006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 05/24/2023] [Accepted: 05/28/2023] [Indexed: 06/12/2023] Open
Abstract
BACKGROUND The incidence of early-onset colorectal cancer (CRC) is increasing. Many guidelines recommend initiating screening at 45 years. This study investigated the detection rate of advanced colorectal neoplasm (ACRN) by using fecal immunochemical tests (FITs) in individuals aged 40-49 years. METHODS PubMed, Embase, and Cochrane Library databases were searched from inception to May 2022. The primary outcomes were the detection rates and positive predictive values of FITs for ACRN and CRC in people aged 40-49 (younger age group) and ≥50 years (average risk group). RESULTS Ten studies with 664,159 FITs were included. The FIT positivity rate was 4.9% and 7.3% for the younger age and average risk groups, respectively. Younger individuals with positive FIT results had significantly higher risks of ACRN (odds ratio [OR] 2.58, 95% confidence interval [CI] 1.79-3.73) or CRC (OR 2.86, 95% CI 1.59-5.13) than did individuals in the average-risk group, regardless of FIT results. Individuals aged 45-49 years with positive FIT results had a similar risk of ACRN (OR 0.80, 95% CI 0.49-1.29) to that of people aged 50-59 years with positive FIT results, although significant heterogeneity was observed. The positive predictive values of the FIT were 10-28.1% for ACRN and 2.7-6.8% for CRC in the younger age group. CONCLUSION The detection rate of ACRN and CRC based on FITs in individuals aged 40-49 years is acceptable, and the yield of ACRN might be similar between individuals aged 45-49 and 50-59 years. Further prospective cohort and cost-effective analysis are warranted.

Cost-effectiveness of population-wide genomic screening for Lynch syndrome in the United States. Genet Med 2022; 24:1017-1026. [PMID: 35227606 DOI: 10.1016/j.gim.2022.01.017] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 01/21/2022] [Accepted: 01/24/2022] [Indexed: 12/12/2022] Open
Abstract
PURPOSE Genomic screening for Lynch syndrome (LS) could prevent colorectal cancer (CRC) by identifying high-risk patients and instituting intensive CRC screening. We estimated the cost-effectiveness of a population-wide LS genomic screening vs family history-based screening alone in an unselected US population. METHODS We developed a decision-analytic Markov model including health states for precancer, stage-specific CRC, and death and assumed an inexpensive test cost of $200. We conducted sensitivity and threshold analyses to evaluate model uncertainty. RESULTS Screening unselected 30-year-olds for LS variants resulted in 48 (95% credible range [CR] = 35-63) fewer overall CRC cases per 100,000 screened individuals, leading to 187 quality-adjusted life-years (QALYs; 95% CR = 123-260) gained at an incremental cost of $24.6 million (95% CR = $20.3 million-$29.1 million). The incremental cost-effectiveness ratio was $132,200, with an 8% and 71% probability of being cost-effective at $100,000 and $150,000 per QALY willingness-to-pay thresholds, respectively. CONCLUSION Population LS screening may be cost-effective in younger patient populations under a $150,000 willingness-to-pay per QALY threshold and with a relatively inexpensive test cost. Further reductions in testing costs and/or the inclusion of LS testing within a broader multiplex screening panel are needed for screening to become highly cost-effective.

Gupta A, Saini SD, Naylor KB. Increased Driving Distance to Screening Colonoscopy Negatively Affects Bowel Preparation Quality: an Observational Study. J Gen Intern Med 2021; 36:1666-1672. [PMID: 33791932 PMCID: PMC8175497 DOI: 10.1007/s11606-020-06464-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Accepted: 12/13/2020] [Indexed: 10/21/2022]
Abstract
BACKGROUND To prepare for colonoscopy, patients must consume a bowel purgative and travel from their home to the site of their procedure. The timing of bowel purgative ingestion predicts bowel preparation quality. Currently, it is not known if driving distance impacts bowel preparation quality or adenoma detection. OBJECTIVE This study investigates the effect of driving distance on bowel preparation and adenoma detection. DESIGN This is a cross-sectional retrospective analysis of outpatient screening colonoscopy procedures that were completed at an academic medical center. PARTICIPANTS A total of 5089 patients who completed screening colonoscopy across 3 procedure units were analyzed. MAIN MEASURES Description of bowel preparation was dichotomized to either adequate or inadequate. Patient residential addresses were converted into geographic coordinates for geospatial analysis of driving distance to their colonoscopy site. KEY RESULTS Median driving distance was 13.1 miles. Eighty-nine percent of patients had an adequate bowel preparation. The rate of adenoma detection was 37%. On multivariable logistic regression adjusting for age, sex, race, insurance, endoscopist, and site, increasing driving distance (10-mile increments) was negatively associated with adequate bowel preparation (odds ratio = 0.91; 95% confidence interval 0.85 to 0.97), while adenoma detection was positively associated with adequate bowel preparation (odds ratio = 1.53; 95% confidence interval 1.24 to 1.88) but not with driving distance (odds ratio = 1.02; 95% confidence interval 0.98 to 1.06). Driving distances of 30 miles or less were associated with adequate bowel preparation (odds ratio = 1.37; 95% confidence interval 1.09 to 1.72). CONCLUSIONS Increasing driving distance to screening colonoscopy was negatively associated with adequate bowel preparation but not adenoma detection. Among an academic medical center population, the likelihood of adequate bowel preparation was highest in patients traveling 30 miles or less to their screening colonoscopy. Patient driving distance to colonoscopy is an important consideration in optimizing screening colonoscopy quality.

Abstract
Colorectal cancer (CRC) is the third most common cancer in men and women in the United States. CRC screening efforts are directed toward removal of adenomas and sessile serrated lesions and detection of early-stage CRC. The purpose of this article is to update the 2009 American College of Gastroenterology CRC screening guidelines. The guideline is framed around several key questions. We conducted a comprehensive literature search to include studies through October 2020. The inclusion criteria were studies of any design with men and women age 40 years and older. Detailed recommendations for CRC screening in average-risk individuals and those with a family history of CRC are discussed. We also provide recommendations on the role of aspirin for chemoprevention, quality indicators for colonoscopy, approaches to organized CRC screening and improving adherence to CRC screening. CRC screening must be optimized to allow effective and sustained reduction of CRC incidence and mortality. This can be accomplished by achieving high rates of adherence, quality monitoring and improvement, following evidence-based guidelines, and removing barriers through the spectrum of care from noninvasive screening tests to screening and diagnostic colonoscopy. The development of cost-effective, highly accurate, noninvasive modalities associated with improved overall adherence to the screening process is also a desirable goal.

Abstract
Cancer is characterized by uncontrolled growth and spread of abnormal cells. It is the second most common cause of death in the United States, and a significant proportion can be prevented. Underrepresented and underserved populations are less likely to receive routine medical procedures and experience a lower quality of health services. Despite the increase in cancer screening, there are disparities in the incidence and mortality of various cancers. These disparities are not fully explained by the correlations between minority race and lower socioeconomic status or minority race and insurance status. Considerations for global cancer control in low-resource settings are presented.

Abstract
Answer questions and earn CME/CNE Screening to detect polyps or cancer at an early stage has been shown to produce better outcomes in colorectal cancer (CRC). Programs with a population-based approach can reach a large majority of the eligible population and can offer cost-effective interventions with the potential benefit of maximizing early cancer detection and prevention using a complete follow-up plan. The purpose of this review was to summarize the key features of population-based programs to increase CRC screening in the United States. A search was conducted in the SCOPUS, OvidSP, and PubMed databases. The authors selected published reports of population-based programs that met at least 5 of the 6 International Agency for Research on Cancer (IARC) criteria for cancer prevention and were known to the National Colorectal Cancer Roundtable. Interventions at the level of individual practices were not included in this review. IARC cancer prevention criteria served as a framework to assess the effective processes and elements of a population-based program. Eight programs were included in this review. Half of the programs met all IARC criteria, and all programs led to improvements in screening rates. The rate of colonoscopy after a positive stool test was heterogeneous among programs. Different population-based strategies were used to promote these screening programs, including system-based, provider-based, patient-based, and media-based strategies. Treatment of identified cancer cases was not included explicitly in 4 programs but was offered through routine medical care. Evidence-based methods for promoting CRC screening at a population level can guide the development of future approaches in health care prevention. The key elements of a successful population-based approach include adherence to the 6 IARC criteria and 4 additional elements (an identified external funding source, a structured policy for positive fecal occult blood test results and confirmed cancer cases, outreach activities for recruitment and patient education, and an established rescreening process).
