Abstract
INTRODUCTION Population health interventions to increase colorectal cancer (CRC) screening rates often exclude individuals with a family history of CRC, and interventions to increase screening in this high-risk group are rare. We aimed to determine the screening rate and barriers and facilitators to screening in this population to inform interventions to increase screening participation. METHODS We performed a retrospective chart review and cross-sectional survey of patients excluded from mailed fecal immunochemical test (FIT) outreach because of a family history of CRC in a large health system. We used χ 2 , Fisher exact, and Student t tests to compare demographic and clinical characteristics of patients overdue and not overdue for screening. We then administered a survey (mailed and telephone) to overdue patients to assess barriers and facilitators to screening. RESULTS There were 296 patients excluded from mailed FIT outreach, and 233 patients had a confirmed family history of CRC. Screening participation was low (21.9%), and there were no significant demographic or clinical differences between those overdue and not overdue for screening. There were 79 survey participants. Major patient-reported barriers to screening colonoscopy were patient forgetfulness (35.9%), fear of pain during colonoscopy (17.7%), and hesitancy about bowel preparation (29.4%). To facilitate screening colonoscopy, patients recommended reminders (56.3%), education about familial risk (50%), and colonoscopy education (35.9%). DISCUSSION Patients with a family history of CRC who are excluded from mailed FIT outreach have low screening rates and report multiple mutable barriers to screening. They warrant targeted efforts to increase screening participation.

Abstract
OBJECTIVE For colon cancer patients, one goal of health insurance is to improve access to screening that leads to early detection, early-stage diagnosis, and polyp removal, all of which results in easier treatment and better outcomes. We examined associations among health insurance status, mode of detection (screen detection vs symptomatic presentation), and stage at diagnosis (early vs late) in a diverse sample of patients recently diagnosed with colon cancer from the Chicago metropolitan area. METHODS Data came from the Colon Cancer Patterns of Care in Chicago study of racial and socioeconomic disparities in colon cancer screening, diagnosis, and care. We collected data from the medical records of non-Hispanic Black and non-Hispanic White patients aged ≥50 and diagnosed with colon cancer from October 2010 through January 2014 (N = 348). We used logistic regression with marginal standardization to model associations between health insurance status and study outcomes. RESULTS After adjusting for age, race, sex, and socioeconomic status, being continuously insured 5 years before diagnosis and through diagnosis was associated with a 20 (95% CI, 8-33) percentage-point increase in prevalence of screen detection. Screen detection in turn was associated with a 15 (95% CI, 3-27) percentage-point increase in early-stage diagnosis; however, nearly half (47%; n = 54) of the 114 screen-detected patients were still diagnosed at late stage (stage 3 or 4). Health insurance status was not associated with earlier stage at diagnosis. CONCLUSIONS For health insurance to effectively shift stage at diagnosis, stronger associations are needed between health insurance and screening-related detection; between screening-related detection and early stage at diagnosis; or both. Findings also highlight the need to better understand factors contributing to late-stage colon cancer diagnosis despite screen detection.

Abstract
BACKGROUND Early detection of pancreatic ductal adenocarcinoma (PDAC) is an important goal for improving survival. Individuals who meet published guidelines for surveillance may be underidentified, and family communication about risk represents a pathway to increasing participation in surveillance. We investigated the uptake of and barriers to surveillance in at-risk relatives of clinic patients. METHODS We conducted a retrospective record review of patients with personal or family history of PDAC evaluated over 12 months. The first relative presenting to clinic (proband) reported surveillance status and reasons for nonparticipation for at-risk relatives. Descriptive analyses and Fisher's exact tests were conducted to evaluate differences in surveillance participation. RESULTS Among 193 at-risk relatives, 21% were in surveillance. The primary reasons for nonparticipation were lack of awareness (36%) and lack of interest (24%). Neither the sex nor the cancer status of probands impacted surveillance. At-risk relatives with familial pancreatic cancer (FPC) who also carried relevant pathogenic germline variants (PGVs) were more likely to undergo surveillance than those with FPC or PGVs alone (P = .003). Among families with PGVs, 59% of relatives potentially eligible for surveillance had not completed genetic testing. CONCLUSION PDAC surveillance is underutilized in high-risk families. Communication interventions to address informational needs and decisional support could improve outcomes.

Cancer Causes Control 2020; 31:1039-1048.

Abstract
BACKGROUND Out-of-pocket costs may significantly dampen patients' willingness to adopt preventive procedures. This is especially true for colonoscopies, which typically involved relatively high cost-sharing requirements prior to the Affordable Care Act (ACA) implementation in 2011. PURPOSE We aim to examine the effects of income-related disparities in colonoscopy use in the years prior to and immediately after the implementation of the ACA. Further, we quantify the contributions of different factors in explaining the disparities in the use of colonoscopies among elderly population with health insurance coverage. METHODS Five cycles (2008, 2010, 2012, 2014, and 2016) of Behavioral Risk Factor Surveillance System data were utilized. To examine income-related disparities in the use of CRC, individuals aged 65-75 were included, and the concentration index (CI) was calculated before and after the implementation of ACA. To identify and quantify the contribution of different factors, a decomposition analysis of CI was conducted. RESULTS CIs decreased from 0.1935 in pre-ACA years to 0.1813 in the post-ACA years among the elderly, indicating that the disparities in the use of colonoscopy was relatively low and the disparities index declined after the implementation of ACA. Decomposition analyses showed that whereas decreases in disparities derived largely from income and educational level, higher level of income and educational attainment were major contributors to the observed disparities in colonoscopy use. CONCLUSIONS Our findings indicate that the ACA's removal of financial barriers may have contributed toward the reduction in disparities of colonoscopy use. More direct interventions, e.g., improved knowledge, better access and lower indirect cost will be helpful in improving screening among low-income and low-educational attainment households.

Abstract
OBJECTIVE This descriptive study was conducted in order to determine the risk factors, symptoms and awareness of health sciences students with regards to colorectal cancer (CRC). METHODS This study included 1,028 health science students from two different universities. Data for this study were collected via a questionnaire form that included questions about CRC risk factors, protective approaches and symptoms. Frequencies, percentages and averages of the data were assessed with Kruskal-Wallis and Mann-Whitney U tests. RESULTS The most frequent risk factors of the students (mean age: 21.25 years) were smoking (90.5%), excessive alcohol consumption (87.4%), family history of cancer (84.2%) and obesity (82.6%), while the most common protective approaches were smoking cessation, avoiding alcohol, regular physical activity and a low-fat diet. There was a significant difference in the CRC awareness of students in terms of gender, the department and grade level at which they were studying, and having a family history of cancer. CONCLUSION Results of this study revealed that students had a sufficient awareness about risk factors and what they could do to diminish their risk, but their knowledge about CRC symptoms was less than expected. We believe that health sciences students should be given more education on CRC symptoms.

Abstract
OBJECTIVES To characterize early adoption of a novel multitarget stool DNA (MT-sDNA) screening test for colorectal cancer (CRC) screening and to test the hypothesis that adoption differs by demographic characteristics and prior CRC screening behavior and proceeds predictably over time. PATIENTS AND METHODS We used the Rochester Epidemiology Project research infrastructure to assess the use of the MT-sDNA screening test in adults aged 50 to 75 years living in Olmsted County, Minnesota, in 2014 and identified 27,147 individuals eligible or due for screening colonoscopy from November 1, 2014, through November 30, 2015. We used electronic Current Procedure Terminology and Health Care Common Procedure codes to evaluate early adoption of the MT-sDNA screening test in this population and to test whether early adoption varies by age, sex, race, and prior CRC screening behavior. RESULTS Overall, 2193 (8.1%) and 974 (3.6%) individuals were screened by colonoscopy and MT-sDNA, respectively. Age, sex, race, and prior CRC screening behavior were significantly and independently associated with MT-sDNA screening use compared with colonoscopy use after adjustment for all other variables (P<.05 for all). The rates of adoption of MT-sDNA screening increased over time and were highest in those aged 50 to 54 years, women, whites, and those who had a history of screening. The use of the MT-sDNA screening test varied predictably by insurance coverage. The rates of colonoscopy decreased over time, whereas overall CRC screening rates remained steady. CONCLUSION The results of the present study are generally consistent with predictions derived from prior research and the diffusion of innovation framework, pointing to increasing use of the new screening test over time and early adoption by younger patients, women, whites, and those with prior CRC screening.

Abstract
Persons with a family history (FH) of colorectal cancer (CRC) or adenomas that are not due to known hereditary syndromes have an increased risk for CRC. An understanding of these risks, screening recommendations, and screening behaviors can inform strategies for reducing the CRC burden in these families. A comprehensive review of the literature published within the past 10 years has been performed to assess what is known about cancer risk, screening guidelines, adherence and barriers to screening, and effective interventions in persons with an FH of CRC and to identify FH tools used to identify these individuals and inform care. Existing data show that having 1 affected first-degree relative (FDR) increases the CRC risk 2-fold, and the risk increases with multiple affected FDRs and a younger age at diagnosis. There is variability in screening recommendations across consensus guidelines. Screening adherence is <50% and is lower in persons under the age of 50 years. A provider's recommendation, multiple affected relatives, and family encouragement facilitate screening; insufficient collection of FH, low knowledge of guidelines, and poor family communication are important barriers. Effective interventions incorporate strategies for overcoming barriers, but these have not been broadly tested in clinical settings. Four strategies for reducing CRC in persons with familial risk are suggested: 1) improving the collection and utilization of the FH of cancer, 2) establishing a consensus for screening guidelines by FH, 3) enhancing provider-patient knowledge of guidelines and communication about CRC risk, and 4) encouraging survivors to promote screening within their families and partnering with existing screening programs to expand their reach to high-risk groups.

Abstract
Only about half of eligible individuals undergo colon cancer screening. We have limited knowledge about the patient beliefs that adversely affect screening decisions and about which beliefs might be amenable to change through education. As part of a clinical trial, 641 rural Iowans, aged 52 to 79 years, reported their beliefs about colon cancer screening in response to a mailed questionnaire. Consenting subjects were randomized into four groups, which were distinguished by four levels of increasingly intensive efforts to promote screening. Two of the groups received mailed educational materials and completed a follow-up questionnaire, which allowed us to determine whether their beliefs about screening changed following the education. We also completed a factor analysis to identify underlying (latent) factors that might explain the responses to 33 questions about readiness, attitudes, and perceived barriers related to colon cancer screening. The strongest predictors of a patient's stated readiness to be screened were a physician's recommendation to be screened (1 point difference on 10-point Likert scale, 95 % confidence interval [CI], 0.5 to 1.6 point difference), a family history of colon cancer (0.85-point Likert scale difference, 95 % CI, 0.1 to 1.6), and a belief that health-care decisions should be mostly left to physicians rather than patients (Spearman correlation coefficient 0.21, P < .001). Of the 33 questionnaire items about screening beliefs, 11 (33 %) changed favorably following the educational intervention. In the factor analysis, the 33 items were reduced to 8 underlying factors, such as being too busy to undergo screening and worries about screening procedures. We found a limited number of underlying factors that may help explain patient resistance to colon cancer screening.

Abstract
Colorectal cancer (CRC) is a leading cause of cancer-related death in the world. Clinically, early detection of the disease is the most effective approach to tackle this tough challenge. Discovery and development of reliable and effective diagnostic tools for the assessment of prognosis and prediction of response to drug therapy are urgently needed for personalized therapies and better treatment outcomes. Among many ongoing efforts in search for potential CRC biomarkers, MS-based translational proteomics provides a unique opportunity for the discovery and application of protein biomarkers toward better CRC early detection and treatment. This review updates most recent studies that use preclinical models and clinical materials for the identification of CRC-related protein markers. Some new advances in the development of CRC protein markers such as CRC stem cell related protein markers, SRM/MRM-MS and MS cytometry approaches are also discussed in order to address future directions and challenges from bench translational research to bedside clinical application of CRC biomarkers.

Abstract
BACKGROUND Ethnic minorities, especially African Americans and Latinos, bear a disproportionate burden of colorectal cancer (CRC), as reflected in incidence, cancer stage, and mortality statistics. In all ethnic groups, first-degree relatives (FDRs) of CRC cases are at an elevated disease risk. However, underuse of CRC screening persists and is particularly evident among minority groups. The current study tested a stepped intervention to increase CRC screening among an ethnically diverse sample of FDRs of CRC cases. METHODS A statewide cancer registry was used to recruit CRC cases and through them their FDRs. Relatives who were not current on CRC screening were randomized to intervention or usual-care control arms. The stepped intervention consisted of ethnically targeted and individually tailored print materials followed by telephone counseling for those unscreened at 6 months. RESULTS The study sample of 1280 individuals consisted of 403 Latino, 284 African American, 242 Asian, and 351 white FDRs. Statistically significant effects were observed for the cumulative print plus telephone intervention at 12 months (26% in the intervention vs 18% in the control group) and the print intervention alone at 6 months (15% in the intervention vs 10% in the control group). The effect of the print intervention alone versus the cumulative interventions was not statistically significantly different. Stratified analyses indicated that the intervention was effective among white, Latino, and Asian individuals, but not among African-Americans. CONCLUSIONS Overall, the intervention was effective in increasing screening rates. Oversampling racial/ethnic minorities allowed for the examination of effects within subgroups, revealing no effect among African American individuals. This finding illustrates the importance of including sufficient numbers of participants from diverse ethnic subgroups in intervention research to enable such stratified analyses.

Abstract
INTRODUCTION Colonoscopy screening reduces colorectal cancer (CRC) incidence and mortality. CRC screening is recommended at age 50 for average-risk people. Screening of first-degree relatives of CRC patients is recommended to begin at age 40 or 10 years before the age at diagnosis of the youngest relative diagnosed with CRC. CRC incidence has increased recently among younger Americans while it has declined among older Americans. The objective of this study was to determine whether first-degree relatives of CRC patients are being screened according to recommended guidelines. METHODS We studied colonoscopy screening rates among the US population reporting a CRC family history using 2005 and 2010 National Health Interview Survey data. RESULTS Of 26,064 study-eligible respondents, 2,470 reported a CRC family history; of those with a family history, 45.6% had a colonoscopy (25.2% in 2005 and 65.8% 2010). The colonoscopy rate among first-degree relatives aged 40 to 49 in 2010 (38.3%) was about half that of first-degree relatives aged 50 or older (69.7%). First-degree relatives were nearly twice as likely as nonfirst-degree relatives to have a colonoscopy (adjusted odds ratio [AOR], 1.7; 95% confidence interval, 1.5-1.9), but those aged 40 to 49 were less likely to have a colonoscopy than those in older age groups (AOR, 2.6 for age 50-64; AOR, 3.6 for age ≥65). Interactions with age, insurance, and race/ethnicity were not significant. Having health insurance tripled the likelihood of screening. CONCLUSION Despite a 5-fold increase in colonoscopy screening rates since 2005, rates among first-degree relatives younger than the conventional screening age have lagged. Screening promotion targeted to this group may halt the recent rising trend of CRC among younger Americans.

Abstract
Financial barriers can substantially delay medical care seeking. Using patient narratives provided by 252 colorectal cancer patients, we explored the experience of financial barriers to care seeking. Of the 252 patients interviewed, 84 identified financial barriers as a significant hurdle to obtaining health care for their colorectal cancer symptoms. Using verbatim transcripts of the narratives collected from patients between 2008 and 2010, three themes were identified: insurance status as a barrier (discussed by n = 84; 100% of subsample), finding medical care (discussed by n = 30; 36% of subsample) and, insurance companies as barriers (discussed by n = 7; 8% of subsample). Our analysis revealed that insurance status is more nuanced than the categories insured/uninsured and differentially affects how patients attempt to secure health care. While barriers to medical care for the uninsured have been well documented, the experiences of those who are underinsured are less well understood. To improve outcomes in these patients it is critical to understand how financial barriers to medical care are manifested. Even with anticipated changes of the Affordable Care Act, it remains important to understand how perceived financial barriers may be influencing patient behaviors, particularly those who have limited health care options due to insufficient health insurance coverage.

Abstract
OBJECTIVES To describe the development of a multi-component colorectal cancer educational tool for female breast cancer survivors through a cooperative group and public health partnership. DATA SOURCES PubMed, World Wide Web, guidelines from professional organizations, surveys and focus groups with breast cancer survivors. CONCLUSION Collaboration is at the core of cooperative group and public health research. This partnership led to the development of a colorectal cancer educational tool for breast cancer survivors. Focus groups revealed that female breast cancer survivors were receptive to education on colorectal cancer screening. IMPLICATIONS FOR NURSING PRACTICE Nurses are instrumental in research collaborations between cooperative groups and public health. The colorectal educational intervention for breast cancer survivors serves as an exemplar of partnerships leading to innovative research planning and implementation outcomes.
