Abstract
BACKGROUND The rapid and accurate discrimination of colorectal carcinoma (CRC) and polyps at the molecular level enables early intervention of CRC, which can greatly improve the 5-year survival rate of patients. Here we reported the potential of conductive polymer spray ionization mass spectrometry (CPSI-MS) in successfully screening CRC according to the serum metabolic profile. METHODS Trace intravenous blood (50 μL) was collected from 60 colorectal carcinoma (CRC) and 60 polyp patients, respectively. After centrifugation, serum (2 μL) was loaded onto the tip of conductive polymer to form a dried serum spot. When the 5 μL methanol-water (1:1, v/v) extraction solvent was spiked onto the dried serum spot followed with +4.5 kV high voltage applied on the polymer tip, the extracted components will be ionized and carried into the MS system for direct metabolic profiling. FINDINGS There were 51 metabolites discovered to be significantly changed in CRC serum compared to polyps. Combining these metabolites as the characteristic panel, the ideal diagnostic performance was achieved by Lasso regression model with the accuracy of 88.3%. INTERPRETATION This pilot study demonstrated the potential of CPSI-MS as a cost-effective tool in large-scale CRC screening in the high-risk population.

Abstract
The National Colorectal Cancer Roundtable (NCCRT) is an organization of organizations with staffing, funding and leadership provided by the American Cancer Society (ACS) and guidance and funding by the Centers for Disease Control and Prevention (CDC). In 2014, ACS, CDC, and the NCCRT launched the 80% by 2018 campaign. This highly successful initiative activated hundreds of organizations to prioritize colorectal cancer screening, disseminated smart, evidence-based interventions, and ultimately led to 9.3 million more Americans being up to date with screening compared with the precampaign rate. It's new campaign, 80% in Every Community, is designed to address persistent screening disparities.

Abstract
Background To explore how individuals reason when they make decisions about participating in colorectal cancer (CRC) screening. Methods Individuals randomized to FIT or colonoscopy included in the Screening of Swedish Colons (SCREESCO) program was invited to focus group discussions and individual telephone interviews. The concept of shared decision-making (SDM: information; values/preferences; involvement) was used as a matrix for the analyses. To validate findings, additional focus group discussions using the nominal group technique were performed. Results Lack of knowledge of CRC and CRC screening was prominent for participants and non-participants, while the results differed between the groups in relation to their values and preferences. The influence of significant others promoted participation while it prevented it among non-participants. Those who participated and those who did not made it clear that there was no need to involve health care professionals when making the decision. Conclusions Based on the results, a display of different ways to spread knowledge and communicate about CRC and CRC-screening could be applied such as, community-based information campaigns, decisions aids, interactive questionnaires, chat-functions and telephone support. The disparity in values and preferences between participants and non-participants may be the key to understand why non-participants make their decisions not to participate and warrant further exploration.

Abstract
BACKGROUND Colorectal cancer (CRC) screening rates are low among underserved populations. High-quality patient-physician communication potentially influences patients' willingness to undergo CRC screening. Community health centers (HCs) provide comprehensive primary health care to underserved populations. This study's objectives were to ascertain national CRC screening rates and to explore the relations between sociodemographic characteristics and patient-provider communication on the receipt of CRC screening among HC patients. METHODS Using 2014 Health Center Patient Survey data, bivariate and multivariate analyses examined the association of sociodemographic variables (sex, race/ethnicity, age, geography, preferred language, household income, insurance, and employment status) and patient-provider communication with the receipt of CRC screening. RESULTS Patients between the ages of 65 and 75 years (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.33-4.64) and patients not in the labor force (aOR, 2.32; 95% CI, 1.37-3.94) had higher odds of receiving CRC screening, whereas patients who were uninsured (aOR, 0.33; 95% CI, 0.18-0.61) and patients who were non-English-speaking (aOR, 0.42; 95% CI, 0.18-0.99) had lower odds. Patient-provider communication was not associated with the receipt of CRC screening. CONCLUSIONS The CRC screening rate for HC patients was 57.9%, whereas the rate was 65.1% according to the 2012 Behavioral Risk Factor Surveillance System and 58.2% according to the 2013 National Health Interview Survey. The high ratings of patient-provider communication, regardless of the screening status, suggest strides toward a patient-centered medical home practice transformation that will assist in a positive patient experience. Addressing the lack of insurance, making culturally and linguistically appropriate patient education materials available, and training clinicians and care teams in cultural competency are critical for increasing future CRC screening rates.

Abstract
The main aim is to examine whether patients' viewing time on information about colorectal cancer (CRC) screening before a primary care physician (PCP) visit is associated with discussion of screening options during the visit. We analyzed data from a multi-center randomized controlled trial of a tailored interactive multimedia computer program (IMCP) to activate patients to undergo CRC screening, deployed in primary care offices immediately before a visit. We employed usage time information stored in the IMCP to examine the association of patient time spent using the program with patient-reported discussion of screening during the visit, adjusting for previous CRC screening recommendation and reading speed.On average, patients spent 33 minutes on the program. In adjusted analyses, 30 minutes spent using the program was associated with a 41% increase in the odds of the patient having a discussion with their PCP (1.04, 1.59, 95% CI). In a separate analysis of the tailoring modules; the modules encouraging adherence to the tailored screening recommendation and discussion with the patient's PCP yielded significant results. Other predictors of screening discussion included better self-reported physical health and increased patient activation. Time spent on the program predicted greater patient-physician discussion of screening during a linked visit.Usage time information gathered automatically by IMCPs offers promise for objectively assessing patient engagement around a topic and predicting likelihood of discussion between patients and their clinician.

Abstract
The purpose of this study is to provide process data from campaigns (2009-2010) to improve colorectal cancer (CRC; intervention) screening and fruit and vegetable (F&V; comparison) consumption in 12 Appalachian Ohio counties. County-specific campaigns included one billboard, posters, and articles for local newspapers. Participants in CRC screening counties who reported seeing CRC screening billboards had greater intention to talk to a doctor/nurse about screening in the next 6 months (odds ratio [OR] = 2.92, 95% confidence interval [CI; 1.71, 4.99]) and had twice the odds of talking to a doctor/nurse about screening in the past year (OR = 2.15, 95% CI [1.29, 3.60]) compared to those who did not see the billboards. Participants in F&V counties who reported seeing F&V billboards had twice the odds (OR = 2.27, 95% CI [1.35, 3.84]) of talking to a doctor/nurse in the past year about F&Vs compared to those who did not see the billboards. Participants who reported campaign exposure lived closer to the billboards compared to those who did not report campaign exposure (mean distance in miles from home to billboard: 8.8 vs. 10.9; p < .01). Most participants reported campaign messages were clear and important. Results suggest that partnering with community members to develop campaign materials is important to ensure cultural appropriateness and that exposure to the intervention components may affect health-related outcomes.

Abstract
BACKGROUND In 1998, the Institute of Medicine (IOM) noted that the American healthcare system had many problems. A major concern was the pervasiveness of medical errors. Electronic medical records (EMR) were introduced for myriad of reasons, one being to reduce these errors. Within the EMR, order sets have been shown to reduce variation in clinical practice and improve the quality of care. However, the lack of standardization in these sets enables peculiar orders, such as fecal occult blood test (FOBT) in the heparin drip order set at our hospital, to be surprisingly included. Our study was conducted to evaluate the consequences associated with having FOBT in this order set. METHODS A retrospective study of 898 adult hospitalized patients over a 6-month period, who had a heparin drip ordered at a single academic center, was conducted. The main focus of our study was the 130 patients for whom the FOBT was sent. RESULTS Fifteen percent (n=130) of patients started on IV heparin had FOBT sent, of which 33 (25%) came back positive. Approximately one-third (36%) of the positive results were documented by a provider, either in a progress note or discharge summary. In eight instances of a positive FOBT (24%), the heparin drip was stopped. For 10 patients with a positive test (30%), gastroenterology was consulted, and 4 (12%) patients had inpatient endoscopy. Five patients with positive FOBT died while in the hospital (15%) as compared to seven patients (7%) in the negative FOBT group, p<0.05. CONCLUSIONS Most patients started on heparin did not have FOBT tested, and the results changed management infrequently, even when positive. The regular review of all order sets is imperative to ensure that they remain evidenced-based and sensible.

Abstract
Colorectal cancer (CRC) was the second most common cancer among women in 2008, accounting for 571,000 cases, and 9.4% of all cancer cases afflicting women worldwide. According to the World Health Organization (WHO) and the Iraqi National Cancer Registry (INCR), Iraq has seen a steady rise in CRC rates among its general population over the past several decades. Despite Iraq's increasing national incidence of CRC and the growth of the US' Iraqi immigrant population over the last 10 years, little remains known about the prevalence of CRC among the latter population, their knowledge of CRC and associated risk factors, or their behavioral intent and practices regarding CRC screening. The aims of this study were to (1) examine the knowledge of and adherence to National Cancer Institute screening recommendations for CRC among a population of Iraqi women living in the Washington D.C. Metropolitan Area and (2) test the efficacy of a one-time educational intervention conducted using linguistically and culturally appropriate materials to raise awareness of, and promote future adherence to, CRC screening methods. This descriptive study used a pre/post design with a 12-month follow-up. Following extensive dissemination of information regarding the study in the Iraqi American community in the study location, 50 women were initially recruited, of whom 32 participated in the study. The study's findings revealed that the participants generally had low baseline levels of CRC screening adherence and preventive knowledge that significantly improved after the intervention as demonstrated by pre- and post-assessments of knowledge and behavior. These findings could be used to raise awareness (1) among clinicians regarding the need for early detection and screening of and referral for CRC treatment among Iraqi American women and (2) among Iraqi American women about risk factors for this disease and the importance of early detection and screening. The study also highlights the need for a larger study of knowledge, attitudes, and perceptions among both this population and the clinicians who serve them.

Abstract
BACKGROUND Evidence-based preventive services for early detection of cancer and other health conditions offer profound health benefits, yet Americans receive only half of indicated services. Policy initiatives promote the adoption of information technologies to engage patients in care. We developed a theory-driven interactive preventive health record (IPHR) to engage patients in health promotion. The model defines five levels of functionality: (1) collecting patient information, (2) integrating with electronic health records (EHRs), (3) translating information into lay language, (4) providing individualized, guideline-based clinical recommendations, and (5) facilitating patient action. It is hypothesized that personal health records (PHRs) with these higher levels of functionality will inform and activate patients in ways that simpler PHRs cannot. However, realizing this vision requires both technological advances and effective implementation based upon clinician and practice engagement. METHODS/DESIGN We are starting a two-phase, mixed-method trial to evaluate whether the IPHR is scalable across a large number of practices and how its uptake differs for minority and disadvantaged patients. In phase 1, 40 practices from three practice-based research networks will be randomized to add IPHR functionality to their PHR versus continue to use their existing PHR. Throughout the study, we will engage intervention practices to locally tailor IPHR content and learn how to integrate new functions into their practice workflow. In phase 2, the IPHR to all nonintervention practices to observe whether the IPHR can be implemented more broadly (Scalability). Phase 1 will feature an implementation assessment in intervention practices, based on the RE-AIM model, to measure Reach (creation of IPHR accounts by patients), Adoption (practice decision to use the IPHR), Implementation (consistency, fidelity, barriers, and facilitators of use), and Maintenance (sustained use). The incremental effect of the IPHR on receipt of cancer screening tests and shared decision-making compared to traditional PHRs will assess Effectiveness. In phase 2, we will assess similar outcomes as phase 1 except for effectiveness. DISCUSSION This study will yield information about the effectiveness of new health information technologies designed to actively engage patients in their care as well as information about how to effectively implement and disseminate PHRs by engaging clinicians.

Abstract
BACKGROUND Screening reduces colorectal cancer mortality, but many persons remain unscreened. Screening with a blood test could improve screening rates. We estimated the comparative effectiveness and cost-effectiveness of colorectal cancer screening with emerging biomarkers, illustrated by a methylated Septin 9 DNA plasma assay ((m)SEPT9), versus established strategies. METHODS We conducted a cost-utility analysis using a validated decision analytic model comparing (m)SEPT9, fecal occult blood testing (FOBT), fecal immunochemical testing (FIT), sigmoidoscopy, and colonoscopy, projecting lifetime benefits and costs. RESULTS In the base case, (m)SEPT9 decreased colorectal cancer incidence by 35% to 41% and colorectal cancer mortality by 53% to 61% at costs of $8,400 to $11,500/quality-adjusted life year gained versus no screening. All established screening strategies were more effective than (m)SEPT9. FIT was cost saving, dominated (m)SEPT9, and was preferred among all the alternatives. Screening uptake and longitudinal adherence rates over time strongly influenced the comparisons between strategies. At the population level, (m)SEPT9 yielded incremental benefit at acceptable costs when it increased the fraction of the population screened more than it was substituted for other strategies. CONCLUSIONS (m)SEPT9 seems to be effective and cost-effective compared with no screening. To be cost-effective compared with established strategies, (m)SEPT9 or blood-based biomarkers with similar test performance characteristics would need to achieve substantially higher uptake and adherence rates than the alternatives. It remains to be proven whether colorectal cancer screening with a blood test can improve screening uptake or long-term adherence compared with established strategies. IMPACT Our study offers insights into the potential role of colorectal cancer screening with blood-based biomarkers.

Abstract
BACKGROUND Colorectal cancer is a leading cause of cancer mortality. Screening can be effective but is underutilized. System- or multi-level interventions could be effective at increasing screening, but most have been implemented and evaluated in higher-resource settings such as health maintenance organizations. Given the disparities evident for colorectal cancer and the potential for screening to improve outcomes, there is a need to expand this work to include diverse settings, including those who treat economically disadvantaged patients. This paper describes the study protocol for a trial designed to increase colorectal cancer screening in those 'safety-net' health centers that serve underinsured and uninsured patients. This trial was designed and is being implemented using a community-based participatory approach. METHODS/DESIGN We developed a practical clinical cluster-randomized controlled trial. We will recruit 16 community health centers to this trial. This systems-level intervention consists of a menu of evidence-based implementation strategies for increasing colorectal cancer screening. Health centers in the intervention arm then collaborate with the study team to tailor strategies to their own setting in order to maximize fit and acceptability. Data are collected at the organizational level through interviews, and at the provider and patient levels through surveys. Patients complete a survey about their healthcare and screening utilization at baseline, six months, and twelve months. OUTCOMES The primary outcome is colorectal cancer screening by patient self-report, supplemented by a chart-audit in a subsample of patients. Implementation outcomes informed by the Reach, Efficacy/Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) conceptual framework will be measured at patient, provider, and practice levels. DISCUSSION Our study is one of the first to integrate community participatory strategies to a randomized controlled trial in a healthcare setting. The multi-level approach will support the ability of the intervention to affect screening through multiple avenues. The participatory approach will strengthen the chance that implementation strategies will be maintained after study completion and, supports external validity by increasing health center interest and willingness to participate. TRIAL REGISTRATION NCT01299493.

Abstract
BACKGROUND Gender differences have been documented among patients diagnosed with colorectal cancer (CRC). It is still not clear, however, how these differences have changed over the past 30 years and if these differences vary by geographic areas. We examined trends in CRC incidence between 1975 and 2006. METHODS The study population consisted of 373,956 patients ≥40 years diagnosed with malignant CRC between 1975 and 2006 who resided in one of the nine Surveillance, Epidemiology and End Results (SEER) regions of the United States. Age-adjusted incidence rates over time were reported by gender, race, CRC subsite, stage, and SEER region. RESULTS Overall, CRC was diagnosed in roughly equal numbers of men (187,973) and women (185,983). Men had significantly higher age-adjusted CRC incidence rates across all categories of age, race, tumor subsite, stage, and SEER region. Gender differences in CRC age-adjusted incidence rates widened slightly from 1975 to 1988, reached a peak in 1985-1988, and have narrowed over time since 1990. The largest gap and decline in CRC incidence rates between men and women were observed among those ≥80 years (p<0.001), followed by those 70-79 and then 60-69 years. Gender differences in CRC incidence rates for the 40-49 and 50-59 age categories were small and increased only slightly over time (p=0.003). CONCLUSIONS Higher CRC age-adjusted incidence among men than among women has persisted over the past 30 years. Although gender differences narrowed in the population ≥60 years, especially from 1990 to 2006, gender gaps, albeit small ones, in those younger than 60 increased over time. Future studies may need to examine the factors associated with these differences and explore ways to narrow the gender gap.

Abstract
OBJECTIVE Compliance with colorectal cancer screening recommendations requires considerable conscious effort on the part of the individual patient, making an individual's decisions about engagement in screening an important contributor to compliance or noncompliance. The objective of this paper was to examine the effectiveness of individual-level behavior theories and their associated constructs in accounting for engagement in colorectal cancer screening behavior. METHODS We reviewed the literature examining constructs from formal models of individual-level health behavior as factors associated with compliance with screening for colorectal cancer. All published studies examining one or more constructs from the health belief model, theory of planned behavior, transtheoretical model, or social cognitive theory and their relation to screening behavior or behavioral intentions were included in the analysis. RESULTS By and large, results of studies supported the theory-based predictions for the influence of constructs on cancer screening behavior. However, the evidence base for many of these relations, especially for models other than the health belief model, is quite limited. CONCLUSIONS Suggestions are made for future research on individual-level determinants of colorectal cancer screening.

Abstract
BACKGROUND Eliciting patients' preferences within a framework of shared decision making (SDM) has been advocated as a strategy for increasing colorectal cancer (CRC) screening adherence. Our objective was to assess the effectiveness of a novel decision aid on SDM in the primary care setting. METHODS An interactive, computer-based decision aid for CRC screening was developed and evaluated within the context of a randomized controlled trial. A total of 665 average-risk patients (mean age, 57 years; 60% female; 63% black, 6% Hispanic) were allocated to 1 of 2 intervention arms (decision aid alone, decision aid plus personalized risk assessment) or a control arm. The interventions were delivered just prior to a scheduled primary care visit. Outcome measures (patient preferences, knowledge, satisfaction with the decision-making process [SDMP], concordance between patient preference and test ordered, and intentions) were evaluated using prestudy/poststudy visit questionnaires and electronic scheduling. RESULTS Overall, 95% of patients in the intervention arms identified a preferred screening option based on values placed on individual test features. Mean cumulative knowledge, SDMP, and intention scores were significantly higher for both intervention groups compared with the control group. Concordance between patient preference and test ordered was 59%. Patients who preferred colonoscopy were more likely to have a test ordered than those who preferred an alternative option (83% v. 70%; P < 0.01). Intention scores were significantly higher when the test ordered reflected patient preferences. CONCLUSIONS Our interactive computer-based decision aid facilitates SDM, but overall effectiveness is determined by the extent to which providers comply with patient preferences.

Abstract
A community needs assessment focused on colorectal cancer (CRC) screening knowledge, behaviors, and barriers was completed in one Ohio Appalachia county. A CRC screening media campaign was developed based on the findings from the needs assessment and feedback was obtained about the media campaign. The survey was completed by 170 self-reported average-risk adults. In a multivariate model, the CRC screening rate was higher for participants who had received a doctor's recommendation (OR = 6.09) and had adequate CRC knowledge (OR = 2.88), and it was lower among participants employed full-time (OR = 0.23). Having health insurance (OR = 4.20) and being married (OR = 2.58) was associated with having received a doctor's recommendation for screening. Campaign feedback using a second survey completed by self-reported average-risk adults (n = 61) revealed that 69% recognized the campaign image and message, with a billboard being the most cited source. This study highlights the importance of involving community members in the development of CRC screening programs to reduce cancer disparities in Appalachia.

Abstract
The DR-70® (FDP) test was the first cancer test cleared by USFDA for monitoring colorectal cancer (CRC) since Carcinoembryonic Antigen (CEA) in 1982. Conservatively, 50% of biopsy-positive CRC patients have negative CEA values. DR-70 and CEA values were compared for 113 CRC monitoring patients. Total concordance rates for DR-70 and CEA were 0.665 and 0.686, respectively. CRC patient pairs were grouped based on their CEA value to deduce DR-70's effectiveness at monitoring patients with low CEA values. DR-70 had 12% to 100% greater positive concordance rates than CEA in this group. DR-70 is a welcome new option for CRC patients.

Abstract
Colorectal cancer (CRC) is the most common cancer in the Nordic countries after breast and prostate cancer. About 15,000 new cancers are diagnosed and more than 7000 patients will die from CRC in 2005. CRC fulfils most of the criteria for applying screening; the natural history is well known compared with many other cancers. CRC may be cured by detection at an early stage and even prevented by removal of possible precursors like adenomas. Faecal occult blood test is the only CRC screening modality that has been subjected to adequately sized randomised controlled trials (RCT) with long-term follow-up results, using Hemoccult-II. Sensitivity for strictly asymptomatic CRC is less than 30% for a single screening round, but programme sensitivity has been estimated to be more. Biennial screening with un-rehydrated Hemoccult-II slides has shown a CRC mortality reduction of 15-18% after approximately 10 years of follow-up in those targeted for screening. For those attending, the mortality reduction has been estimated at 23%. Denmark has decided to do feasibility studies to try to evaluate whether a population-based screening run by the community will have the same effect as has been demonstrated in the randomised trials. In Norway the government has accepted no formal population-based screening. In Finland, the Ministry of Social Affairs and Health made a recommendation in 2003 to the municipalities to run a randomised feasibility study with FOBT screening for colorectal cancer as a public health policy that is repeated every second year. In 2004 the first municipalities started. It has been claimed that today Sweden cannot afford CRC screening despite the potential mortality benefit. There is sufficient evidence for the efficacy of screening for colorectal cancer with fecal occult blood test every second year. There is, however, only little evidence on the effectiveness of screening when run as a public health service and there is insufficient knowledge of harmful effects and costs, even in RCTs.

Abstract
BACKGROUND In a low socioeconomic-status population of Latina women, we evaluated the potential of storytelling (ST) as a culturally aligned narrative method to promote colorectal cancer (CRC) prevention and screening, compared to a risk tool (RT)-based intervention. METHODS Seventy-eight women were randomized in this pilot study to one of two brief interventions to communicate CRC risk reduction options: ST or an RT. Measures of behavioral intentions relative to CRC prevention and screening were obtained following the intervention. RESULTS Mean scores for intent to obtain and recommend endoscopy to others were significantly better for participants receiving ST than RT (P = .038 and P = .011, respectively). All participants expressed intent to increase fruit and vegetable consumption and physical activity in response to interventions. Post-intervention perceptions of cancer risk and fear of CRC were not significantly different for participants receiving ST compared with RT. Pre- to post-intervention perceptions of risk increased in ST and decreased in RT, while decreases in fear were similar across both intervention groups. CONCLUSIONS Storytelling may be an effective approach for changing CRC risk-related behavioral intentions among Latinas. Mediating factors (such as perceived risk or fear) often used to predict behavior change may not adequately explain the potential persuasive mechanisms of storytelling.

Abstract
The "war on cancer" in the United States has been viewed primarily as an effort to develop and disseminate cancer cures, but cancer is far more easily prevented than cured. There are three major approaches to cancer prevention: Primary prevention, through reduction in risk factors and changes to the environment that reduce human exposure to widely-consumed cancer-promoting agents. The most important actions for primary prevention of cancer are those that reduce tobacco use through taxation, smoke-free environment policies, advertising restrictions, counter-advertising, and cessation programs. The World Health Organization's MPOWER package outlines these actions, each of which covered less than 5% of people in the world in 2007. Similarly, cancer can be prevented by reducing alcohol consumption through policies such as alcohol taxes and limits on alcohol sales, and restoring caloric balance through policies such as creating healthier food environments and engineering the built environment to increase opportunities for physical activity. Vaccination is an effective approach to preventing specific virus-associated cancers, such as using human papillomavirus vaccine to prevent cervical cancer and hepatitis B virus vaccine to prevent hepatocellular cancer. Secondary prevention reduces cancer mortality through screening and early treatment; this approach has been used successfully for breast and cervical cancer but is still underused against colon cancer. Progress can be made in all three approaches to cancer prevention, but will require a greater emphasis on public health programs and public policy. Winning the war on cancer will require a much larger investment in prevention to complement efforts to improve treatment.

Abstract
INTRODUCTION Approximately 150,000 people are diagnosed with colorectal cancer each year and 56,000 may die from it annually in the United States. Colorectal cancer is the second leading cause of cancer deaths in the USA and yet, when diagnosed at an early stage, it is one of the most preventable cancers. According to the US Preventive Services Task Force, initial screening for colorectal cancer is recommended in people above 50 years of age with average risk and earlier in people with a strong family history and other risk factors. Adenomatous polyps are considered as precursors of colorectal cancer. Removal of polyps and postpolypectomy surveillance reduces the overall mortality from colorectal cancer. DISCUSSION According to updated guidelines in 2006, a 3-year-follow-up colonoscopy is recommended in patients with adenomatous polyps>or=1 cm. An important factor in the surveillance and prevention of colorectal cancer in postpolypectomy patients is compliance with follow-up colonoscopy. In the present article, we provide an overview of the importance of postpolypectomy surveillance and summarize the compliance data for postpolypectomy surveillance. Compliance to postpolypectomy surveillance varies from one study to another and it should be expected that the compliance with follow-up would be low outside of clinical trials. Some measures that can improve patient compliance include patient education regarding a need of follow-up screening, reminder letters, and alerts in patient's charts. CONCLUSION In conclusion, effective surveillance screening with good patient compliance in postpolypectomy patients will contribute significantly in reducing colon cancer morbidity and mortality.

Abstract
Colon cancer screening rates in women are low. Whether screening for breast and cervical cancer is associated with colon cancer screening behavior is unknown but could provide linkage opportunities. To identify the extent to which both breast and cervical cancer screening increases uptake of colon cancer screening among women in New York City. Women at least 50 years old completed questionnaires for the New York Cancer Project. Analyses compared rates of endoscopic colon cancer screening with adherence to screening recommendations for breast and cervical cancer. Of the 3,386 women, 87.8% adhered to breast and cervical cancer screening guidelines, yet only 42.1% had received endoscopic colon cancer screening. Most women with colon cancer screening (95%) also reported past mammogram and Pap-smear. In multivariable analysis, women who adhered to the other two procedures were more likely to have had colon cancer screening than women with no prior history (OR = 4.4; CI = 2.36, 8.20), after accounting for age, race/ethnicity, insurance status, family history of cancer and income. Significant predictors of endoscopic colon cancer screening included: age over 65 years (OR = 1.63; CI = 1.23, 2.15) with 50-65 years old as the reference, any health insurance (OR = 2.18; CI = 1.52, 3.13) and a family history of cancer (OR = 1.38; CI = 1.17, 1.61). Colorectal cancer screening remains low, even among women who undergo other cancer screening tests. Opportunities to link cancer screening tests to encourage colon cancer screening merit closer attention.

Abstract
The Centers for Disease Control and Prevention's Screen for Life campaign in March 1999 followed by the creation of National Colorectal Cancer Awareness Month in March 2000 heralded a surge in media attention to promote awareness about CRC and stimulate interest in screening. Our objective was to assess whether these campaigns have achieved their goal of educating the public about CRC and screening. The study sample was comprised of mostly unscreened, average-risk, English-speaking patients aged 50-75 years seen in an urban primary care setting. Knowledge was assessed using a 12-item true/false questionnaire based primarily on the content of key messages endorsed by the National Colorectal Cancer Roundtable (Cancer 95:1618-1628, 2002) and adopted in many of the media campaigns. Multiple linear regression was performed to identify demographic correlates of knowledge. A total of 356 subjects (83% <age 65, 58% female, 60% Black, 7% Hispanic, 60% <or=high school degree, 31% prior FOBT ) were surveyed. Most respondents (>or=67%) were aware of who gets CRC, age to initiate screening, the goals of screening and potential benefits. Fewer were aware that removing polyps can prevent CRC and that both polyps and CRC may be asymptomatic. Knowledge scores were lower among Blacks and those with a high school degree or less. Race and education were independent correlates of knowledge. These data suggest that recent media campaigns have been effective in increasing public awareness about CRC risk and screening but important gaps in knowledge remain.

PATIENT EDUCATION AND COUNSELING 2007; 68:145-52. [PMID: 17517486 DOI: 10.1016/j.pec.2007.04.004] [Citation(s) in RCA: 33] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/01/2007] [Revised: 04/02/2007] [Accepted: 04/11/2007] [Indexed: 05/12/2023]
Abstract
OBJECTIVE The Hispanic/Latino population has been documented as having the lowest colorectal cancer (CRC) screening rates in the United States, putting this group at-risk for late-stage presentation of disease. We assessed knowledge, attitudes, and behavior regarding CRC screening to inform the development of messages that promote screening among Hispanic/Latino patients. METHODS In-person structured interviews with Spanish-speaking adults age 50-80 at two clinics and a senior center in a Hispanic/Latino community (N=234). RESULTS Most (67.1%) participants had no more than an eighth-grade education and 63.3% reported their reading ability as less than "very good." Only 18.4% of participants correctly identified the colon on a diagram; 19.2% correctly described at least one aspect of a polyp. Less than half of the participants perceived themselves as at-risk for CRC, and less than one-third knew about any of the standard screening tests. After hearing descriptions of the screening tests, participants perceived stool cards as easier, safer, less painful, less embarrassing, and less scary than endoscopy (p<.001). Approximately two-thirds of unscreened patients said that screening had never been mentioned or suggested to them; about one-quarter said they did not get screened because they felt fine or were not worried. Over 96% of participants said they would get screened if a doctor suggested it. CONCLUSION Assessing knowledge, attitudes, beliefs, and experiences in the community of interest is a promising approach for developing effective targeted health messages. PRACTICE IMPLICATIONS Messages to increase CRC screening knowledge and behavior in the Hispanic/Latino community should address risk factors, identify relevant anatomy, explain polyps and their asymptomatic presentation, and clearly describe options.

Abstract
BACKGROUND The cost of an individual colonoscopy is an important determinant of the overall cost and cost-effectiveness of colorectal cancer screening. Published cost estimates vary widely and typically report institutional costs derived from gross-costing methods. OBJECTIVE Perform a cost analysis of colonoscopy using micro-costing and time-and-motion techniques to determine the total societal cost of colonoscopy, which includes direct health care costs as well as direct non-health care costs and costs related to patients' time. The design is prospective cohort. The participants were 276 contacted, eligible patients who underwent colonoscopy between July 2001 and June 2002, at either a Veterans' Affairs Medical Center or a University Hospital in the Southeastern United States. MAJOR RESULTS The median direct health care cost for colonoscopy was $379 (25%, 75%; $343, $433). The median direct non-health care and patient time costs were $226 (25%, 75%; $187, $323) and $274 (25%, 75%; $186, $368), respectively. The median total societal cost of colonoscopy was $923 (25%, 75%; $805, $1047). The median direct health care, direct non-health care, patient time costs, and total costs at the VA were $391, $288, $274, and $958, respectively; analogous costs at the University Hospital were $376, $189, $368, and $905, respectively. CONCLUSION Microcosting techniques and time-and-motion studies can produce accurate, detailed cost estimates for complex medical interventions. Cost estimates that inform health policy decisions or cost-effectiveness analyses should use total costs from the societal perspective. Societal cost estimates, which include patient and caregiver time costs, may affect colonoscopy screening rates.

Abstract
This study assessed current practice and methods for improvement in the management of families with hereditary non-polyposis colorectal cancer (HNPCC). HNPCC families registered at five London Genetics Centres and a specialised Colorectal family cancer clinic (CFCC) were identified. Ascertainment of management and outcome details were obtained by scrutiny of patient records and by correspondence with General practitioners (GPs). Two hundred and three families with HNPCC were identified. 79.5% (403/507) of at-risk relatives ascertained were contacted by the genetics centres, and 80.2% (65/81) by the CFCC (P = 1.0). 54.8% (211/385) of probands and relatives within genetics centres' catchment areas were advised to undertake a surveillance programme, compared with 82.1% (64/78) of those cared for by the CFCC (P < 4.2 x 10(-6)). Adherence to surveillance guidelines was 76.6% (49/64) in individuals cared for by the only centre that undertook responsibility for surveillance follow-up (CFCC) and 41.7% (88/211) for the genetics centres, which did not assume responsibility (P < 8.9 x 10(-7)) (using two sided P-values for P (O > or = E/O < or = E)). 15.3% of GPs were unaware their patient had been recommended a surveillance programme, 65% did not know who was responsible for ensuring surveillance follow-up. A questionnaire to fifteen UK genetics centres demonstrated that the majority (86.7%) did not assume responsibility for surveillance follow-up. Since surveillance adherence is clearly better where centres assume responsibility for follow-up, it is recommended that regional or national registers of HNPCC families be developed and maintained to ensure effective management.

Abstract
Cancer Prevention is an emerging field, capturing the old traditional concept of anticipating the development of a major disease and preventing its full impact by early detection, treatment, or aborting the tumorigenic process by a "molecular vaccine" and alleviating the full impact of the disease. Surgeons are important clinician scientists who can carry this discipline forward and develop its full potential in the clinics and in the community. Advances in molecular biology, genetics, and other technologies have permitted seminal understanding of the carcinogenic pathways and identification of targets and intermediate end points in neoplasia. In this review, we will see that we have the means of preventing significant numbers of colorectal carcinomas (CRC).

Abstract
Endoscopic removal of colorectal adenomas reduces the incidence and mortality of colorectal cancer (CRC), but follow-up surveillance is recommended. Compliance with the Dutch surveillance guidelines and detection of neoplasia during follow-up has been evaluated in daily practice. From 1987 to 1996, 383 consecutive patients with colorectal adenomas (56.4% male, 61.8+/-11.3 years) were included and followed until December 2000. The mean follow-up was 80.5+/-42.5 months with 2.2+/-0.9 follow-up endoscopies. A total of 32.5 and 27.3% of follow-up endoscopies were performed >25% (time between advised and actual endoscopy) too late or too early, respectively. At the end of follow-up, 33.4% of patients had left the follow-up (two-thirds died) and 60.1% were known with co-morbidity. A first, second, third, fourth and fifth follow-up endoscopy had been performed in 327, 238, 132, 64 and 35 patients, respectively. Adenomatous polyps (with high-risk polyps) were detected in 100% (42.6%) of the index endoscopies and in 25.1% (17.4%), 23.9% (10.5%), 28.0% (12.1%), 34.4% (25.0%) and 37.1% (17.1%) of the first to fifth follow-up endoscopy, respectively. CRC was diagnosed in seven patients (46.1+/-22.9 months after index endoscopy), resulting in a standardized incidence ratio of 1.4 (confidence interval 0.6-3.0, P=0.4) compared to the general population. In this daily practice, high numbers of total and high-risk adenomatous polyps were found during follow-up surveillance. The incidence of CRC was not significantly different from the general population, which might be due to the intensive follow-up and removal of polyps. These findings support the importance of follow-up surveillance. However, the high overall morbidity and mortality should be taken into account when selecting patients for an intensive follow-up programme.

Abstract
BACKGROUND Although strong scientific evidence has shown that screening for colorectal cancer saves lives, most U.S. adults who are at the recommended age are not being screened. Prior studies suggest that barriers to routine screening vary by race, ethnicity, socioeconomic status, urban/rural residence, health insurance status, and factors related to health care providers and the health care environment. Relatively few studies, however, have identified and tested intervention approaches to promote routine colorectal cancer screening among diverse populations. METHODS The Division of Cancer Prevention and Control at CDC has funded ongoing projects to develop and test interventions to promote routine colorectal cancer screening among medically underserved populations in Appalachia, the Lower Rio Grande Valley in Texas, the High Plains region of Colorado, and other U.S. communities. RESULTS This article provides an overview of colorectal cancer screening intervention studies currently funded by CDC that focus on a wide range of populations, including medically underserved persons who live in predominately rural areas, Hispanic and non-Hispanic persons, urban African Americans, persons with low health literacy, and persons enrolled in managed care organizations. CONCLUSIONS These CDC-funded intervention research projects are likely to contribute importantly to evidence about what works to promote colorectal cancer screening in diverse U.S. communities. .

Abstract
Improving health in the twenty-first century means adopting a new approach that engages the public, the business community, and public policymakers more than in the past. This approach depends on a well-informed public that practices individual wellness, values community health, and advocates achieving both. It requires a business community that views public health as an essential component of a healthy business climate and productive workforce. It also requires informed policymakers who agree that an investment in public health has important community benefit. Public health professionals must effectively engage these three groups if the public health system is to be transformed.

Abstract
Gastroenterology lags behind other specialties such as cardiology in the quality of its evidence base for clinical practice. One area where this is particularly evident is in cancer prevention, despite developments in chemoprevention strategies for high-risk patients. For chemoprevention strategies to be successful, we need appropriate clinical networks and translational science infrastructures, model chemoprevention agents and multiple, large, flexible and randomized clinical trials. Translational science must also be embedded into large-scale, long-term, randomized clinical trials that have hard endpoints, so that irrefutable evidence of the longevity of treatment efficacy can be gathered. We also need to be able to identify an individual's cancer risk using valid global patient populations, so that medical benefits can be applied to all, regardless of ethnicity, sex, economic status, age and comorbidities. The future success of gastrointestinal chemoprevention relies on fostering a closer link between basic pharmaceutical research and clinical applications, in a 'bench to bedside and back' manner. In this review we systematically assess the evidence for various cancer prevention strategies, especially chemoprevention, and highlight the obstacles to further exploitation of this knowledge base.

Abstract
Adnab-9 binding in colonic tissue and effluent has been associated with an increased risk for colorectal neoplasia. We investigated if fecal binding by Adnab-9 may be used as a marker for colorectal neoplasia. A fecal-Adnab-9 ELISA was performed on samples of 249 patients and colonoscopic pathology results correlated. Fecal Adnab-9 binding was seen in 63% of patients with colorectal neoplasia (59% with colorectal cancer and 83% with adenoma), 33% with inflammatory bowel disease, 0% with hyperplastic polyps and 10% of controls. We conclude that fecal Adnab-9 binding is a promising risk marker for colorectal neoplasia.

Abstract
OBJECTIVE Computer-assisted telephone interviewing (CATI) systems used by telephone counselors (TCs) may be efficient mechanisms to counsel patients on cancer and recommended preventive screening tests in order to extend a primary care provider's reach to his/her patients. The implementation process of such a system for promoting colorectal (CRC) cancer screening using a computer-assisted telephone interview (CATI) system is reported in this paper. METHODS The process evaluation assessed three components of the intervention: message production, program implementation and audience reception. RESULTS Of 1181 potentially eligible patients, 1025 (87%) patients were reached by the TCs and 725 of those patients (71%) were eligible to receive counseling. Five hundred eighty-two (80%) patients agreed to counseling. CONCLUSIONS It is feasible to design and use CATI systems for prevention counseling of patients in primary care practices. PRACTICE IMPLICATIONS CATI systems have the potential of being used as a referral service by primary care providers and health care organizations for patient education.

Abstract
BACKGROUND Studies exploring CRC testing prevalence and correlates within US populations have provided limited and sometimes conflicting information. The most recent national-level reports have described US usage of CRC tests but none have considered only those tests done specifically for screening reasons as an outcome variable. METHODS Using the NHIS 2000 sample of >or=50 year-old, we assessed screening behavior using an outcome variable accounting for (1) any combination of recommended tests (2) done within their respective time guidelines, and (3) specifically for screening purposes. RESULTS Only 25.8% (95% CI: 24.9-26.7%) of the population reported getting a test done for screening purposes within the recommended time. Most (>85%) of the FOBTs and only about 60% of endoscopies were done for screening. Among those who had an endoscopy within the recommended time, Blacks were more likely than Whites to report screening as the purpose of the test. Hispanics had the lowest test usage irrespective of test time, reason or type. Hispanics were 50% (p<0.001) less likely to be adherent, and Blacks approximately 22% (p<0.01) less likely to be adherent, than Whites. After multivariate adjustment, differences between Whites and Blacks disappeared; Hispanics remained less likely. Increasing education predicted higher adherence among Whites but only undergraduate completion did so among Blacks. Male gender predicted adherence only among Blacks and insurance only among Hispanics. CONCLUSIONS Preventive screening for CRC is lower than estimates from previous studies. Future studies should consider accounting for test purpose. Our findings need confirmation through studies based on objective data.

Abstract
Screening and surveillance substantially reduce both the incidence and mortality of colorectal cancer. Screening of normal-risk individuals may be accomplished by several methods, including fecal occult blood testing, fiberoptic sigmoidoscopy, double contrast barium enema, and colonoscopy. New technologies for screening are being developed, such as fecal immunochemical testing for blood,fecal DNA testing, and virtual colonoscopy. Patients at increased risk for colorectal cancer, such as those with a positive family history, previous adenomatous polyps or cancer, and inflammatory bowel disease, should be offered more intensive evaluation and surveillance.

Abstract
OBJECTIVE The Internet could be a key channel for disseminating information about colorectal cancer (CRC) screening. Little research, however, has systematically examined factors other than writing style related to the reading difficulty of cancer information on the Internet. In the present study we assessed the reading difficulty of 19 CRC Web sites. METHODS We assessed pages within selected sites containing information on CRC screening or prevention using the SMOG readability formula and Suitability Assessment of Materials instrument. RESULTS The average SMOG reading grade level was 12.8. The SAM results indicated common problems with the sites, including (1) lack of review of key ideas; (2) insufficient use of illustrations for key messages; (3) crowded layout and long line lengths; (4) small type size and lack of cues to highlight key content; and (5) lack of interactive features. CONCLUSIONS Many Web sites providing CRC information may be too difficult for the average American adult and much too difficult for adults with limited literacy. The unique features of the Internet that could support learning are not being utilized. The Internet could be a powerful tool for educating individuals about CRC, but the barrier of difficult content must be addressed along with access barriers.

Abstract
BACKGROUND Minority and low-income women receive fewer cancer screenings than other women. OBJECTIVE To evaluate the effect of a telephone support intervention to increase rates of breast, cervical, and colorectal cancer screening among minority and low-income women. DESIGN Randomized, controlled trial conducted between November 2001 and April 2004. SETTING 11 community and migrant health centers in New York City. PATIENTS 1413 women who were overdue for cancer screening. INTERVENTION Over 18 months, women assigned to the intervention group received an average of 4 calls from prevention care managers and women assigned to the control group received usual care. Follow-up data were available for 99% of women, and 91% of the intervention group received at least 1 call. MEASUREMENTS Medical record documentation of mammography, Papanicolaou testing, and colorectal cancer screening according to U.S. Preventive Services Task Force recommendations. RESULTS The proportion of women who had mammography increased from 0.58 to 0.68 with the intervention and decreased from 0.60 to 0.58 with usual care; the proportion who had Papanicolaou testing increased from 0.71 to 0.78 with the intervention and was unchanged with usual care; and the proportion who had colorectal screening increased from 0.39 to 0.63 with the intervention and from 0.39 to 0.50 with usual care. The difference in the change in screening rates between groups was 0.12 for mammography (95% CI, 0.06 to 0.19), 0.07 for Papanicolaou testing (CI, 0.01 to 0.12), and 0.13 for colorectal screening (CI, 0.07 to 0.19). The proportion of women who were up to date for 3 tests increased from 0.21 to 0.43 with the intervention. LIMITATIONS Participants were from 1 city and had access to a regular source of care. Medical records may not have captured all cancer screenings. CONCLUSIONS Telephone support can improve cancer screening rates among women who visit community and migrant health centers. The intervention seems to be well suited to health plans, large medical groups, and other organizations that seek to increase cancer screening rates and to address disparities in care.

Abstract
The aim of the present study was to evaluate to what extent lifestyle-related variables predict participation for flexible sigmoidoscopy (FS) screening when the compliance is relatively high. During 2001, a randomized sample of 6961 men and women, born between 1946 and 1950, were invited to have a flexible sigmoidoscopy screening examination. Attendees (n = 4111) were asked to fill in a questionnaire focusing on physical activity, body weight, smoking habits and diet. The questionnaire was sent by mail to non-attendees (n = 2628) and a randomized corresponding control group not invited to screening (n = 7000). Sixty-one percent attended for screening. The questionnaire response rate among attendees, non-attendees and controls was 97, 11 and 61%, respectively. Attendees were more physically active (P < 0.001), and showed more adherence to general dietary recommendations, compared with controls. Opposing their healthy exercise and dietary habits, however, attendees were more likely to be moderate smokers compared with controls. The present offer of FS screening, achieving a relatively high compliance rate, may have reached attendees using screening as a supplement to an already healthy lifestyle, but also those who seek amelioration through health checks for risks behaviour that they are perfectly well aware of, such as smoking.

Abstract
BACKGROUND Starting in 2001, the state of Maryland established a carefully planned and executed multicomponent intervention to reduce mortality and disparities in colorectal cancer. METHODS In the most populous county, uninsured participants received education and a choice of free screening by fecal occult blood testing (FOBT) or colonoscopy or both. RESULTS Over 2 years, a group of 1,672 uninsured individuals, of whom 90% were minorities, registered with the program. Overall, screening uptake was 41% with colonoscopy, 10% with FOBT, and 10% with both FOBT and colonoscopy. CONCLUSION The choices of colorectal cancer screening modalities by a diverse uninsured population demonstrates the importance of maintaining screening options.

Abstract
OBJECTIVE To determine whether a multimedia computer program could effectively teach patients about fecal occult blood testing (FOBT) and increase screening rates. DESIGN Randomized trial. SETTING University-affiliated, community-based Internal Medicine outpatient practice. PARTICIPANTS All English-speaking patients aged 50 years and older who were offered FOBT screening by their providers were invited to participate. Two hundred and four patients enrolled in the study. Ten patients were later determined to be ineligible. INTERVENTIONS Patients were randomized to either the educational multimedia computer program or usual nurse counseling about FOBT screening. Screening instructions were based on the material pre-printed on each test kit. Educational sessions were held in a private setting immediately after each patient's office visit. MEASUREMENTS AND MAIN RESULTS A knowledge-assessment questionnaire was administered in a blinded fashion by telephone the following day. Successful screening was defined as return of the test kits within 30 d. Completion of the FOBT kits was similar in both groups: 62% (58/93) in the computer group and 63% (64/101) in the nurse group (P=.89). Mean knowledge scores were also similar, but there was a trend toward increased knowledge mastery in the computer group (56% vs 41%, P=.09). CONCLUSIONS A multimedia educational computer program was as effective as usual nurse counseling in educating patients and achieving adherence to FOBT screening. Future studies are needed to determine whether computer-assisted instruction can improve health outcomes.

Abstract
BACKGROUND Prevention benefits from predictive genetic testing for cancer will only be fully realized if appropriate screening is adopted after testing. The current study assessed screening and preventive behaviors during 12 months after predictive genetic testing for hereditary nonpolyposis colorectal carcinoma (HNPCC) in an Australian clinical cohort. METHODS Participants received predictive genetic testing for HNPCC at one of five Australian familial cancer clinics. Data on self-reported screening behaviors (colonoscopy, and endometrial sampling and transvaginal ultrasound for women) and prophylactic surgery (colectomy, and hysterectomy and bilateral oophorectomy for women) were collected using postal questionnaires before (baseline) and 12 months after receipt of genetic test results. Age, gender, perceived risk of cancer, and cancer-specific distress were assessed as predictors of colonoscopic screening. RESULTS In the current study, 114 participants returned baseline questionnaires (32 carriers and 82 noncarriers of an HNPCC mutation). Ninety-eight participants also returned a 12-month follow-up questionnaire. Of those > or = 25 years, 73% reported having had a colonoscopy before genetic testing. At follow-up, 71% (15 of 25) of carriers and 12% (8 of 65) of noncarriers reported having a colonoscopy in the 12 months after receipt of test results. The reduction in colonoscopy among noncarriers was statistically significant (P < 0.001). High perceived risk was associated with colonoscopy at baseline. At follow-up, mutation status was the only variable significantly associated with colonoscopy. Among female mutation carriers, 47% reported having transvaginal ultrasonography and 53% endometrial sampling during follow-up. There was low uptake of prophylactic surgery for colorectal, endometrial, or ovarian carcinomas. CONCLUSIONS The majority of individuals reported appropriate screening behaviors after predictive genetic testing for HNPCC. The small group of noncarriers who had screening after genetic testing might benefit from additional counseling.
