Abstract
Importance The benefits from colorectal cancer (CRC) screening may take 10 to 15 years to accrue. Therefore, screening is recommended for older adults who are in good health. Objective To determine the number of screening colonoscopies done in patients older than 75 years with a life expectancy of fewer than 10 years, diagnostic yield, and associated adverse events within 10 days and 30 days of the procedure. Design This cross-sectional study with a nested cohort between January 2009 and January 2022 in an integrated health system assessed asymptomatic patients older than 75 years who underwent screening colonoscopy in the outpatient setting. Reports with incomplete data, any indication other than screening, patients who had a colonoscopy within the previous 5 years, and patients with a personal history of inflammatory bowel disease or CRC were excluded. Exposures Life expectancy based on a prediction model from previous literature. Main Outcomes and Measures The primary outcome was the percentage of screened patients who had limited (<10 years) life expectancy. Other outcomes included colonoscopy findings and adverse events that developed within 10 days and 30 days of the procedure. Results A total of 7067 patients older than 75 years were included. The median (IQR) age was 78 (77-79) years, 3967 (56%) were women, and 5431 (77%) were White with an average of 2 comorbidities (taken from a select group of comorbidities). The proportion of colonoscopies performed on patients with a life expectancy of fewer than 10 years aged 76 to 80 years was 30% in both sexes and increased with age-82% of men and 61% of women aged 81 to 85 years (71% total), and 100% of patients beyond the age of 85 years. Adverse events requiring hospitalizations were common at 10 days (13.58 per 1000) and increased with age, particularly among patients older than 85 years. The detection of advanced neoplasia varied from 5.4% among patients aged 76 to 80 years to 6.2% in those aged 81 to 85 years and 9.5% among patients older than 85 years (P = .02). Of the total population, 15 patients (0.2%) had invasive adenocarcinoma; among patients with a life expectancy of fewer than 10 years, 1 of 9 was treated, whereas 4 of 6 patients with a life expectancy of greater than or equal to 10 years were treated. Conclusions and Relevance In this cross-sectional study with a nested cohort, most screening colonoscopies performed in patients older than 75 years were in patients with limited life expectancy and associated with increased risk of complications. Colorectal cancer was exceedingly rare.

Abstract
Background Research on the role of body size on cancer screening is mixed with few studies among Latinas in the United States. We evaluated the association between body size and cancer screening adherence among Latinas living in Puerto Rico and the rest of the United States. Methods We conducted a cross-sectional study using 2012-2018 Behavioral Risk Factor Surveillance System data among Latinas 50-64 years of age (n = 16,410). Breast, cervical, and colorectal cancer screening (guideline adherent: yes/no), height and weight were self-reported. Prevalence ratios (PRs) derived from Poisson models were estimated for each cancer screening utilization for Puerto Rico versus rest of the United States by body mass index (BMI) category. Results Nearly a quarter of women lacked adherence with breast and cervical cancer screening and 43.6% were nonadherent to colorectal cancer screening. Latinas with BMI ≥40.0 kg/m2 in both groups were more likely to lack adherence to cervical cancer screening than women with BMI 18.5-24.9 kg/m2. For those with BMI ≥40.0 kg/m2, Latinas in Puerto Rico were more likely to lack adherence to colorectal cancer screening recommendations than Latinas living in the rest of the United States (adjusted PR: 1.38; 95% confidence interval = 1.12-1.70). Conclusions The role of body size in cancer screening utilization among Latinas differs in women living in Puerto Rico versus in the rest of the United States and varies by cancer type. Understanding Latinas' experience can inform culturally adapted interventions to promote cancer screening.

Abstract
Purpose: Health-related behaviors among underweight women have received less attention than overweight and obese women in the United States. Our purposes were to estimate the rate and modifiers of breast, cervical, and colorectal cancer screening adherence among underweight women and compare it to other body mass index (BMI) categories. Materials and Methods: We used sampling weighted data from 2016 Behavioral Risk Factor Surveillance System (BRFSS) of age-eligible women (breast cancer screening, n = 163,164; cervical, n = 113,883 and colorectal, n = 128,287). We defined breast, cervical, and colorectal cancer screening using the US Preventive Services Task Force (USPSTF) guidelines. We calculated the prevalence of screening among four BMI categories (underweight <18.5, normal weight ≥18.5 to <25, overweight ≥25 to <30, and obese ≥30). Logistic regression models assessed the independent effect of BMI on screening adherence. Results: Underweight women had significantly lower breast (62.9%), cervical (67.5%), and colorectal (62.6%) cancer screening rates compared to other BMI categories. In logistic regression models, being underweight was associated with decreased odds of breast (odds ratio [OR] = 0.66; 95% confidence interval [CI] = 0.49-0.88) and cervical (OR = 0.54, 95% CI = 0.34-0.84), but not colorectal (OR = 0.88; 95% CI = 0.66-1.18) cancer screening adherence. We did not demonstrate a significant association between obesity and screening rates for any of the three cancers. Underweight women reported higher rates of smoking and lower levels of educational attainment, income, and insurance coverage compared to all other groups. Higher rates of chronic illness and health access hardship were observed among underweight women. Conclusion: BMI variably affects cancer screening. Compared to normal-weight women, being underweight is associated with breast and cervical cancer screening nonadherence. Promoting breast and cervical cancer screening among this currently underserved population may reduce future disparities.

Cancer fatalism and adherence to national cancer screening guidelines: Results from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Cancer Epidemiol 2019; 60:39-45. [PMID: 30904827 PMCID: PMC10424711 DOI: 10.1016/j.canep.2019.03.003] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2018] [Revised: 02/05/2019] [Accepted: 03/03/2019] [Indexed: 12/30/2022]
Abstract
BACKGROUND Sociocultural factors, such as health insurance status, income, education, and acculturation, predict cancer screening among U.S. Hispanics/Latinos. However, these factors can be difficult to modify. More research is needed to identify individual-level modifiable factors that may improve screening and subsequent cancer outcomes in this population. The aim of this study was to examine cancer fatalism (i.e., the belief that there is little or nothing one can do to lower his/her risk of developing cancer) as a determinant of adherence to national screening guidelines for colorectal, breast, prostate, and cervical cancer among Hispanics/Latinos. METHODS Participants were from the multi-site Hispanic Community Health Study/Study of Latinos (HCHS/SOL) Sociocultural Ancillary Study (N = 5313). The National Cancer Institute (NCI) Health Interview National Trends Survey was used to assess cancer fatalism and receipt of cancer screening. Adherence was defined as following screening guidelines from United States Preventive Services Task Force and the American Cancer Society during the study period. RESULTS Adjusting for well-established determinants of cancer screening and covariates (health insurance status, income, education, acculturation, age, Hispanic/Latino background), lower cancer fatalism was marginally associated with greater adherence to screening for colorectal (OR 1.13, 95% CI [.99-1.30], p = .07), breast (OR 1.16, 95% CI [.99-1.36], p = .08) and prostate cancer (OR 1.18, 95% CI [.97-1.43], p = .10), but not cervical cancer. CONCLUSIONS The associations of cancer fatalism were small and marginal, underlining that sociocultural factors are more robust determinants of cancer screening adherence among Hispanics/Latinos.

Abstract
PURPOSE The prevalence of non-AIDS-related malignancies is on the rise among people aging with HIV population, but the evidence on healthy behaviors including cancer screening practices in this population subgroup is extremely limited. Therefore, we investigated the prevalence of healthy behaviors and sex-specific cancer screening among persons living with HIV, by sex and time since HIV diagnosis. METHODS We included 517 persons living with HIV from the Florida Cohort. Data were obtained from the baseline and follow-up questionnaires, electronic medical records, and Enhanced HIV/AIDS Reporting System. The prevalence of self-reported, age-appropriate cancer screening (anal, colorectal, prostate, breast, and cervical), and healthy behaviors (sustaining healthy body weight, refraining from smoking and alcohol and engaging in physical activity) was compared by sex and years since HIV diagnosis (≤ 13 vs. > 13 years). RESULTS In the analyses by sex, females were more likely to be obese than males (56.5% vs. 22.2%, p < 0.0001). Distribution of healthy behaviors did not differ by time since diagnosis among males and females. In the analysis of age-appropriate screening among males, 64.8% never had an anal Pap-smear, 36.2% never had a colonoscopy, and 38.9% never had prostate cancer screening. In the analysis of age-appropriate screening among females, 50.0% never had an anal Pap-smear, 46.5% never had a colonoscopy, 7.9% never had a cervical Pap-smear, and 12.7% never had a mammogram. The difference in anal Pap-smear by sex was statistically significant (p < 0.0001). Among males, the age-adjusted prevalence of never having a colonoscopy was higher in those who had HIV for ≤ 13 years (50.8% vs. 30.6%, p = 0.03). CONCLUSION The prevalence of selected healthy behaviors and cancer screening differed by sex and/or years since HIV diagnosis suggesting a need for tailored cancer prevention efforts among persons living with HIV via long-term sex-specific interventions.

Abstract
OBJECTIVE To study the degree to which individuals in different trajectories of cigarette smoking from adolescence to the early forties are similar or different in terms of lack of preventive health behaviors (e.g., underuse of preventive health services, unhealthy eating habits) in early midlife. METHODS Participants came from a community-based random sample of residents in two upstate New York counties (N = 548). Data were collected from adolescence to early midlife (mean age = 43 years, standard deviation [SD] = 2.8) at seven time points. Using growth mixture modeling, we statistically identified the number of smoking trajectories. Logistic regression analysis was used to study the relationship between the probabilities of participants' smoking trajectory group membership and lack of preventive behaviors in early midlife. RESULTS Five trajectory groups of cigarette smokers were identified. With controls, as compared with the nonsmoker trajectory group, higher probabilities of belonging to the heavy/continuous smoker trajectory group and the late starter trajectory groups were significantly associated with a higher likelihood of lack of preventive health behaviors (adjusted odds ratio [AOR] = 3.49 and 4.02 respectively). In addition, as compared to the quitter/decreaser trajectory group, higher probabilities of belonging to the heavy/continuous smoker trajectory group and the late starter trajectory group were also significantly associated with a higher likelihood of lack of preventive health behaviors (AOR = 3.51 and 4.04 respectively). CONCLUSIONS Intervention programs may consider focusing on heavy/continuous smokers and late starters in programs designed to promote adequate use of preventive health services and healthy general lifestyles in early midlife.

Abstract
INTRODUCTION Obesity is a major risk factor for colorectal cancer (CRC), particularly among men. The purpose of this study was to characterize the prevalence of guideline-adherent CRC screening among obese adults using nationally representative data, assess trends in screening strategies, and identify obesity-specific screening barriers. METHODS Data from 8,550 respondents aged 50-75 years in the 2010 National Health Interview Survey, representing >70 million adults, were analyzed in 2015 using multivariable logistic regression. Prevalence of guideline-adherent CRC screening, endoscopic versus fecal occult blood test screening, and reasons for non-adherence were compared across BMI categories. RESULTS Obese class III men (BMI ≥40), compared with normal-weight men, were significantly less likely to be adherent to screening guidelines (38.7% vs 55.8%, AOR=0.35, 95% CI=0.17, 0.75); less likely to have used an endoscopic test (36.7% vs 53.0%, AOR=0.37, 95% CI=0.18, 0.79); and had a trend toward lower fecal occult blood test use (4.2% vs 8.9%, AOR=0.42, 95% CI=0.14, 1.27). Among women, odds of guideline adherence and use of different screening modalities were similar across all BMI categories. Reasons for non-adherence differed by gender and BMI; lacking a physician screening recommendation differed significantly among men (29.7% obese class III vs 15.4% non-obese, p=0.04), and pain/embarrassment differed significantly among women (11.6% obese class III vs 2.6% non-obese, p=0.002). CONCLUSIONS Despite elevated risk, severely obese men were significantly under-screened for CRC. Addressing the unique screening barriers of obese adults may promote screening uptake and lessen disparities among the vulnerable populations most affected by obesity.

Abstract
The American Society of Nephrology recommends against routine cancer screening among asymptomatic patients receiving maintenance dialysis on the basis of limited survival benefit. To determine the frequency of colorectal cancer screening among patients on dialysis and the extent to which screening tests were targeted toward patients at lower risk of death and higher likelihood of receiving a kidney transplant, we performed a cohort study of 469,574 Medicare beneficiaries ages ≥50 years old who received dialysis between January 1, 2007 and September 30, 2012. We examined colorectal cancer screening tests according to quartiles of risk of mortality and kidney transplant on the basis of multivariable Cox modeling. Over a median follow-up of 1.5 years, 11.6% of patients received a colon cancer screening test (57.9 tests per 1000 person-years). Incidence rates of colonoscopy, flexible sigmoidoscopy, and fecal occult blood test were 27.9, 0.6, and 29.5 per 1000 person-years, respectively. Patients in the lowest quartile of mortality risk were more likely to be screened than those in the highest quartile (hazard ratio, 1.53; 95% confidence interval, 1.49 to 1.57; 65.1 versus 46.4 tests per 1000 person-years, respectively), amounting to a 33% higher rate of testing. Additionally, compared with patients least likely to receive a transplant, patients most likely to receive a transplant were more likely to be screened (hazard ratio, 1.68; 95% confidence interval, 1.64 to 1.73). Colon cancer screening is being targeted toward patients on dialysis at lowest risk of mortality and highest likelihood of transplantation, but absolute rates are high, suggesting overscreening.

Abstract
BACKGROUND AND AIM Current guidelines recommend colon cancer screening for persons aged over 50 years. However, there are few data on colorectal cancer screening in 40- to 49-year-olds. This study assessed the prevalence and risk factors of colorectal neoplasms in 40- to 49-year-old Koreans. METHODS We analyzed the results of screening colonoscopies of 6680 persons 40-59 years of age (2206 aged 40-49 and 4474 aged 50-59 years). RESULTS The prevalence of overall and advanced neoplasms in the 40- to 49-year age group was lower than in the 50- to 59-year age group (26.7% and 2.4% vs 37.8% and 3.5%, respectively). However, the prevalence of overall and advanced neoplasms increased to 39.1% and 5.4%, respectively, in 45- to 49-year-old individuals with metabolic syndrome. In the 40- to 49-year age group, age, current smoking, and metabolic syndrome were associated with an increased risk of advanced neoplasms (odds ratio [OR] 1.16, 95% confidence interval [CI] 1.04-1.30; OR 3.12, 95% CI 1.20-8.12; and OR 2.00, 95% CI 1.09-3.67, respectively). CONCLUSIONS Individuals aged 40-49 years had a lower prevalence of colorectal neoplasms than those aged 50-59 years, but some 40- to 49-year-olds showed a similar prevalence to those aged 50-59 years. Age, current smoking habits, and metabolic syndrome are associated with an increased risk of advanced neoplasms in subjects aged 40-49 years. Further studies are needed to stratify the risks of colon cancer and guide targeted screening in persons younger than 50 years old.

Abstract
BACKGROUND/AIM Early diagnosis of chronic illnesses and cancers mainly occurs at primary health care centers (PHCs) by primary health care physicians (PHPs). The incidence of colorectal cancer (CRC) in the Kingdom of Saudi Arabia (KSA) is rising and this has been attributed to many factors. The increasing incidence of CRC is compounded by nonadherence to screening recommendations. Therefore, evaluating PHPs knowledge, attitudes, and practices of screening for CRC is clinically important. We aimed to evaluate the knowledge, attitudes, and practices of PHPs regarding CRC screening and to identify the factors associated with nonadherence of PHPs to screening recommendations. MATERIALS AND METHODS PHPs working at three tertiary care centers and PHCs across the city of Jeddah were randomly recruited. Participants were surveyed using a comprehensive questionnaire that recorded data on demographics, qualifications, and knowledge of various modalities and guidelines related to CRC screening. Perspectives about effectiveness of, or adherence to, factors that influence physicians' perspectives or recommendations for CRC screening were also assessed. Logistic regression analysis was used to identify physician characteristics associated with PHPs perspectives and nonadherence to CRC screening. RESULTS A total of 127 PHPs were recruited. The average age of participants was 34 (±8.4) years, 86.6% were native Saudi's and 56.7% were females. The majority of surveys (66.9%) were completed at 24 PHCs and the remaining at hospital-based family medicine clinics. Most of the PHPs (55%) had a bachelor's degree and 31.5% were board-certified or carried a PhD in family medicine; 95% of participants believed that CRC screening in general was effective, but as much as 55% reported that they did not practice screening. The male physicians [odds ratio (OR) = 0.44, 95% confidence interval (CI) = 0.19-0.99, P = 0.048)] and PHPs with only a bachelor degree or less (OR = 0.72, 95% CI = 0.55-0.93, P = 0.011) were less likely to recommend screening for CRC. CONCLUSIONS A considerable proportion of PHPs do not adhere to CRC screening recommendations despite a wide belief that screening is effective. Male PHPs with lower qualifications appear to be less likely to recommend screening.

Clin Colorectal Cancer 2015; 15:e65-74. [PMID: 26792032 DOI: 10.1016/j.clcc.2015.12.003] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2015] [Revised: 12/01/2015] [Accepted: 12/09/2015] [Indexed: 02/08/2023]
Abstract
BACKGROUND A multitarget stool DNA (mt-sDNA) test was recently approved for colorectal cancer (CRC) screening for men and women, aged ≥ 50 years, at average risk of CRC. The guidelines currently recommend a 3-year interval for mt-sDNA testing in the absence of empirical data. We used clinical effectiveness modeling to project decreases in CRC incidence and related mortality associated with mt-sDNA screening to help inform interval setting. MATERIALS AND METHODS The Archimedes model (Archimedes Inc., San Francisco, CA) was used to conduct a 5-arm, virtual, clinical screening study of a population of 200,000 virtual individuals to compare the clinical effectiveness of mt-sDNA screening at 1-, 3-, and 5-year intervals compared with colonoscopy at 10-year intervals and no screening for a 30-year period. The study endpoints were the decrease in CRC incidence and related mortality of each strategy versus no screening. Cost-effectiveness ratios (US dollars per quality-adjusted life year [QALY]) of mt-sDNA intervals were calculated versus no screening. RESULTS Compared with 10-year colonoscopy, annual mt-sDNA testing produced similar reductions in CRC incidence (65% vs. 63%) and related mortality (73% vs. 72%). mt-sDNA testing at 3-year intervals reduced the CRC incidence by 57% and CRC mortality by 67%, and mt-sDNA testing at 5-year intervals reduced the CRC incidence by 52% and CRC mortality by 62%. At an average price of $600 per test, the annual, 3-year, and 5-year mt-sDNA screening costs would be $20,178, $11,313, and $7388 per QALY, respectively, compared with no screening. CONCLUSION These data suggest that screening every 3 years using a multitarget mt-sDNA test provides reasonable performance at acceptable cost.

Abstract
BACKGROUND Ulcerative colitis (UC) patients have an increased risk of developing colorectal carcinoma (CRC). In contrast to clinical and pathogenetic differences, little is known about how prognosis compares between these patients and those with sporadic CRC. The aim of this study was to compare their characteristics and prognosis and identify independent risk factors for patients with UC-associated CRC. METHODS A total of 126 patients who underwent surgery in our department (1984-2010) for UC-associated (n = 63) or sporadic (n = 63) CRC were included in this analysis. Patients were matched according to sex, tumor location, and disease stage. Clinical parameters and overall, recurrence-free, and disease-specific survival were compared. In subgroup analyses, clinical parameters of UC patients were correlated with survival. RESULTS Median follow-up was 129 months in the UC group and 99 months in the sporadic CRC group. UC patients were significantly younger and had more multifocal, high-grade, and mucinous carcinomas. Five-year overall survival rate for UC-associated and sporadic CRC was similar (65.7 vs. 63.2%, p = 0.98). Recurrence-free survival for International Union Against Cancer (UICC) stage II disease was superior in the sporadic CRC group (p = 0.039). In a subgroup analysis of UC patients, a shorter duration of UC (p = 0.045) and male sex (p = 0.005) were associated with a worse prognosis. CONCLUSIONS Despite multiple clinical and histopathologic differences between UC-associated and sporadic CRC patients, overall survival and disease-specific survival are similar. In a subgroup analysis of UC patients with CRC, female sex was associated with a significantly better prognosis. This finding implies that estrogens may play a protective role in UC-associated CRC carcinogenesis.

Abstract
Colorectal cancer (CRC) is one of the leading cancers and cause of cancer deaths in American women and men. Females and males share a similar lifetime cumulative risk of CRC however, substantial differences in risk factors, tumor biology, and effectiveness of cancer prevention services have been observed between them. This review distills the evidence documenting the unique variation observed between the genders relating to CRC risk factors, screening and prevention. Consistent evidence throughout the world demonstrates that women reach equivalent levels of adenomas and CRC as men but it occurs nearly a decade later in life than in their male counterparts. Women have a higher proportion of tumors which are hypermethylated, have microsatellite instability and located in the proximal colon suggesting the serrated pathway may be of greater consequence in them than in men. Other CRC risk factors such as smoking, diet and obesity have been shown to have disparate effects on women which may related to interactions between estrogen exposure, body fat distribution, and the biologic underpinnings of their tumors. There is data showing the uptake, choice, and efficacy of different CRC screening methods in women is dissimilar to that in men. The mortality benefit from FOBT, sigmoidoscopy, and protection from interval CRC by colonoscopy appears to be lower in women than men. A greater understanding of these gender idiosyncrasies will facilitate an personalized approach to CRC prevention and should ultimately lead to a reduced burden of disease.

Abstract
PURPOSE The association between excess body weight and colorectal cancer screening is not well established. The purpose of this analysis was to explore, in the context of patients receiving navigation, whether obesity influences receipt of screening colonoscopy among lower-income Latinos and African Americans. METHODS This sub-analysis was conducted among Latinos and African American participants who received patient navigation and had complete body mass index (BMI) data (n = 520). Cross-sectional survey data were collected at baseline among individuals 50 years and older who were referred by their primary care providers for a colonoscopy at Mount Sinai's Primary Care Clinic. BMI was based on height and weight data from chart review at baseline, and colonoscopy completion status was collected at 1 year post-baseline. RESULTS The mean BMI of the sample was 31.17 kg/m(2), with over half (53 %) of the sample categorized as obese. Rates of colonoscopy screening were high (~80 %), regardless of weight status. Adjusting for age, gender, race/ethnicity, family history of colorectal cancer, smoking status, comorbid conditions, income, marital status, insurance, and education, obesity status was not significantly associated with screening behavior among the entire sample (adjusted OR 0.81, CI 0.49-1.32, p = 0.39) or among stratified race/ethnicity and gender groups. CONCLUSIONS These findings suggest that obesity may not negatively influence receipt of colonoscopy screening in the context of patient navigation among minority participants. Further studies are needed to determine whether this finding will be observed in other populations, with and without the assistance of a patient navigator.

Abstract
Colorectal cancer is the second leading cause of mortality in men and women in the United States. While there is a definite advantage regarding the use of colonoscopies in screening, there is still a lack of widespread acceptance of colonoscopy use in the general public. This is evident by the fact that up to 75% of patients diagnosed with colorectal cancer present with locally advanced disease. In order to make colonoscopy and in turn colorectal cancer screening a patient friendly and a comfortable test some changes in tool are necessary. The conventional colonoscope has not changed much since its development. There are several new advances in colorectal screening practices. One of the most promising new advances is the advent of robotic endoscopic techniques.

Abstract
It is well established that disparities exist for colorectal cancer (CRC) incidence rates and death. With screening, death from CRC may be considered a preventable occurrence. Endoscopy (flexible sigmoidoscopy and colonoscopy) is the only modality with therapeutic benefit of removal of pre-cancerous polyps. The Patient Protection and Affordable Care Act mandated that preventive screening services be covered, which includes endoscopy for colon cancer screening. Recent federal rules have eliminated cost sharing for polyp removal during screening colonoscopy in privately insured patients; however, this has not been mandated for Medicare patients. Understanding the current state of disparities in endoscopy use is important, as these policy changes will affect millions of patients. The purpose of this literature review was to summarize the known research on disparities in endoscopy use for colon cancer screening in the United States and highlight areas for future research.

Abstract
BACKGROUND & AIMS Life expectancy is an important consideration when assessing appropriateness of preventive programs for older individuals. Most studies on this subject have used age cutoffs as a proxy for life expectancy. We analyzed patterns of utilization of screening colonoscopy in Medicare enrollees by using estimated life expectancy. METHODS We used a 5% random national sample of Medicare claims data to identify average-risk patients who underwent screening colonoscopies from 2008 to 2010. Colonoscopies were considered to be screening colonoscopies in the absence of diagnoses for nonscreening indications, which were based on either colonoscopies or any claims in the preceding 3 months. We estimated life expectancies by using a model that combined age, sex, and comorbidity. Among patients who underwent screening colonoscopies, we calculated the percentage of those with life expectancies <10 years. RESULTS Among the 57,597 Medicare beneficiaries 66 years old or older who received at least 1 screening colonoscopy, 24.8% had an estimated life expectancy of <10 years. There was a significant positive association between total Medicare per capita costs in hospital referral regions and the proportion of patients with limited life expectancies (<10 years) at the time of screening colonoscopy (R = 0.25; P < .001, Pearson correlation test). In a multivariable analysis, men were substantially more likely than women to have limited life expectancy at the time of screening colonoscopy (odds ratio, 2.25; 95% confidence interval, 2.16-2.34). CONCLUSIONS Nearly 25% of Medicare beneficiaries, especially men, had life expectancies <10 years at the time of screening colonoscopies. Life expectancy should therefore be incorporated in decision-making for preventive services.

Abstract
BACKGROUND & AIMS Colorectal cancer (CRC) screening guidelines recommend screening schedules for each single type of test except for concurrent sigmoidoscopy and fecal occult blood test (FOBT). We investigated the cost-effectiveness of a hybrid screening strategy that was based on a fecal immunological test (FIT) and colonoscopy. METHODS We conducted a cost-effectiveness analysis by using the Archimedes Model to evaluate the effects of different CRC screening strategies on health outcomes and costs related to CRC in a population that represents members of Kaiser Permanente Northern California. The Archimedes Model is a large-scale simulation of human physiology, diseases, interventions, and health care systems. The CRC submodel in the Archimedes Model was derived from public databases, published epidemiologic studies, and clinical trials. RESULTS A hybrid screening strategy led to substantial reductions in CRC incidence and mortality, gains in quality-adjusted life years (QALYs), and reductions in costs, comparable with those of the best single-test strategies. Screening by annual FIT of patients 50-65 years old and then a single colonoscopy when they were 66 years old (FIT/COLOx1) reduced CRC incidence by 72% and gained 110 QALYs for every 1000 people during a period of 30 years, compared with no screening. Compared with annual FIT, FIT/COLOx1 gained 1400 QALYs/100,000 persons at an incremental cost of $9700/QALY gained and required 55% fewer FITs. Compared with FIT/COLOx1, colonoscopy at 10-year intervals gained 500 QALYs/100,000 at an incremental cost of $35,100/QALY gained but required 37% more colonoscopies. Over the ranges of parameters examined, the cost-effectiveness of hybrid screening strategies was slightly more sensitive to the adherence rate with colonoscopy than the adherence rate with yearly FIT. Uncertainties associated with estimates of FIT performance within a program setting and sensitivities for flat and right-sided lesions are expected to have significant impacts on the cost-effectiveness results. CONCLUSIONS In our simulation model, a strategy of annual or biennial FIT, beginning when patients are 50 years old, with a single colonoscopy when they are 66 years old, delivers clinical and economic outcomes similar to those of CRC screening by single-modality strategies, with a favorable impact on resources demand.

Abstract
BACKGROUND Delivering personal narratives and peer support for CRC screening in an online weight-loss community could be an efficient approach to engaging individuals at increased risk, because obesity is associated with excess colorectal cancer (CRC) mortality and lower screening rates. PURPOSE Evaluate user engagement and impact of narratives and peer support for promoting CRC screening in an online weight-loss community. DESIGN Pilot randomized trial. SETTING/PARTICIPANTS Members of an online weight-loss community who were not up-to-date with CRC screening were enrolled in the study in 2011. INTERVENTION Basic and Enhanced groups (n=153 each) both received education. The Enhanced group also received narratives and peer support for CRC screening in online forums. MAIN OUTCOME MEASURES The main measures were user engagement, psychosocial outcomes, and self-report CRC screening at 6 months. Analyses were conducted with (1) the full sample of participants and (2) a minimum dose sample of those who participated in their assigned intervention to a minimum degree. Analyses were completed in 2012. RESULTS Participants were mostly female (92%) with a mean age of 56 years. More than 90% in both groups viewed the educational information. Only 57% in the Enhanced group joined the online team. The Enhanced group had greater improvement in motivation for screening than the Basic group at 1 month (p=0.03). In the full sample, there was no difference in CRC screening at 6 months (Enhanced 19% vs Basic 16%, adjusted OR=1.33, 95% CI=0.73, 2.42). In the minimum dose sample, fecal occult blood testing was higher in the Enhanced (14%) vs Basic (7%) group (adjusted OR=2.49, 95% CI=1.01, 6.17). CONCLUSIONS Although no between-group differences in CRC screening were seen at 6 months, this study did demonstrate that it is feasible to deploy a narrative and peer support intervention for CRC screening in a randomized trial among members of an online community. However, modifications are needed to improve user engagement. TRIAL REGISTRATION This study is registered at ClinicalTrials.gov NCT01411826.

Abstract
BACKGROUND A previous study utilising oral polyethylene-glycol by Borg et al. concluded that obesity is an independent predictor of inadequate bowel preparation at colonoscopy. AIM To compare bowel preparation quality between obese and non-obese individuals as assessed by Boston bowel preparation scale (BBPS) after using sodium picosulphate. METHODS Prospective recruitment of patients at a day surgical unit in a New South Wales academic hospital. Bowel preparation was with Picoprep in all patients. Body Mass Index and epidemiological details were collected. Bowel preparation efficacy was assessed using the Boston Bowel Preparation Score. RESULTS One hundred and four patients were enrolled prospectively. Five (4.8%) were excluded owing to poor mental capacity. Sixty-three (64%) were non-obese, and 36 (36%) were obese. Fifty-seven (90%) non-obese and 32 (89%) obese patients had good bowel preparation. There was no statistical difference for sodium picosulphate bowel preparation between obese and non-obese individuals (P > 0.99) using Fisher's exact probability tests. The BBPS score in the left colon predicted the overall BBPS score in all patients (P < 0.001). Three of 99 patients (3%) did not tolerate sodium picosulphate, with nausea being the most common side-effect. LIMITATIONS Non-randomised study CONCLUSIONS There was no difference in bowel preparation quality between obese and non-obese patients using a low-volume bowel preparation (sodium picosulphate) and without dose modification of the bowel preparation. Sodium picosulphate was a welltolerated and an effective bowel preparation for obese individuals. With an increasing incidence of obesity and expanding colonoscopic indications within Australia and other Western countries from government-sponsored programs, it is paramount that procedural quality not be compromised in the obese patient.

Abstract
IMPORTANCE Inappropriate use of colonoscopy involves unnecessary risk for older patients and consumes resources that could be used more effectively. OBJECTIVES To determine the frequency of potentially inappropriate colonoscopy in Medicare beneficiaries in Texas and to examine variation among physicians and across geographic regions. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used 100% Medicare claims data for Texas and a 5% sample from the United States from 2000 through 2009. We identified Medicare beneficiaries aged 70 years or older who underwent a colonoscopy from October 1, 2008, through September 30, 2009. MAIN OUTCOME MEASURES Colonoscopies were classified as screening in the absence of a diagnosis suggesting an indication for the procedure. Screening colonoscopy was considered potentially inappropriate on the basis of patient age or occurrence too soon after colonoscopy with negative findings. The percentage of patients undergoing potentially inappropriate screening colonoscopy was estimated for each colonoscopist and hospital service area. RESULTS A large percentage of colonoscopies performed in older adults were potentially inappropriate: 23.4% for the overall Texas cohort and 9.9%, 38.8%, and 24.9%, respectively, in patients aged 70 to 75, 76 to 85, or 86 years or older. There was considerable variation across the 797 colonoscopists in the percentages of colonoscopies performed that were potentially inappropriate. In a multilevel model including patient sex, race or ethnicity, number of comorbid conditions, educational level, and urban or rural residence, 73 colonoscopists had percentages significantly above the mean (23.9%), ranging from 28.7% to 45.5%, and 119 had percentages significantly below the mean (23.9%), ranging from 6.7% to 18.6%. The colonoscopists with percentages significantly above the mean were more likely to be surgeons, graduates of US medical schools, medical school graduates before 1990, and higher-volume colonoscopists than those with percentages significantly below the mean. Colonoscopist rankings were fairly stable over time (2006-2007 vs 2008-2009). There was also geographic variation across Texas and the United States, with percentages ranging from 13.3% to 34.9% in Texas and from 19.5% to 30.5% across the United States. CONCLUSIONS AND RELEVANCE Many colonoscopies performed in older adults may be inappropriate. The likelihood of undergoing potentially inappropriate colonoscopy depends in part on where patients live and what physician they see.

Abstract
To assess the impact of household income and economic recession on participation in CRC screening, we estimated annual participating proportions from 2007 to 2009 for different CRC screening modalities according to household income levels. A total of 8,042 subjects were derived from the fourth Korean National Health and Nutrition Examination Survey (KNHANES IV). Multivariate logistic regression analysis was used to estimate odds ratios and 95% confidence intervals for CRC screening with household income quartiles by gender in each year. People were less likely to attend a high-cost CRC screening such as a sigmoidoscopy or colonoscopy independent of the income quartile during the economic recession. Income disparities for participating in opportunistic cancer screening appear to have existed among both males and females during the three years (2007-2009), but were most distinctive in 2009. An increase in mortality of CRC can therefore be expected due to late detection in periods of economic crisis. Accordingly, the government should expand the coverage of CRC screening to prevent excess deaths by reducing related direct and indirect costs during the economic recession.

Effects of being uninsured or underinsured and living in extremely poor neighborhoods on colon cancer care and survival in California: historical cohort analysis, 1996-2011. BMC Public Health 2012; 12:897.

Abstract
Background We examined the mediating effects of health insurance on poverty-colon cancer care and survival relationships and the moderating effects of poverty on health insurance-colon cancer care and survival relationships among women and men in California. Methods We analyzed registry data for 3,291 women and 3,009 men diagnosed with colon cancer between 1996 and 2000 and followed until 2011 on lymph node investigation, stage at diagnosis, surgery, chemotherapy, wait times and survival. We obtained socioeconomic data for individual residences from the 2000 census to categorize the following neighborhoods: high poverty (30% or more poor), middle poverty (5-29% poor) and low poverty (less than 5% poor). Primary health insurers were Medicaid, Medicare, private or none. Results Evidence of mediation was observed for women, but not for men. For women, the apparent effect of poverty disappeared in the presence of payer, and the effects of all forms of health insurance seemed strengthened. All were advantaged on 6-year survival compared to the uninsured: Medicaid (RR = 1.83), Medicare (RR = 1.92) and private (RR = 1.83). Evidence of moderation was also only observed for women. The effects of all forms of health insurance were stronger for women in low poverty neighborhoods: Medicaid (RR = 2.90), Medicare (RR = 2.91) and private (RR = 2.60). For men, only main effects of poverty and payers were observed, the advantaging effect of private insurance being largest. Across colon cancer care processes, Medicare seemed most instrumental for women, private payers for men. Conclusions Health insurance substantially mediates the quality of colon cancer care and poverty seems to make the effects of being uninsured or underinsured even worse, especially among women in the United States. These findings are consistent with the theory that more facilitative social and economic capital is available in more affluent neighborhoods, where women with colon cancer may be better able to absorb the indirect and direct, but uncovered, costs of care.

Risk stratification for advanced proximal colon neoplasm and individualized endoscopic screening for colorectal cancer by a risk-scoring model. Gastrointest Endosc 2012; 76:818-28.

Abstract
BACKGROUND Only 30% to 40% of patients with advanced proximal neoplasms (APN) have distal colon neoplasms. OBJECTIVE To develop a risk score model for APN and propose an individualized screening protocol for colorectal cancer. DESIGN Retrospective cohort study. SETTING Tertiary-care center. PATIENTS Derivation cohort (6200 adults) and validation cohort (1389 adults). INTERVENTION Screening colonoscopy. MAIN OUTCOME MEASUREMENTS An APN risk score model was developed from the derivation cohort (6200 adults) and was tested in the validation cohort (1389 adults), who underwent screening colonoscopy. RESULTS Age, male sex, and smoking were clinical risk factors for APN. The presence of a distal neoplasm was a sigmoidoscopic risk factor for APN. We calculated APN risk scores (0-8) based on these variables and classified patients as low risk (0-2) or high risk (3-8). In the validation cohort, the relative risk of APN was 3.5-fold higher in the high-risk group than in the low-risk group. Our model suggests that colonoscopy should be performed as an initial screening test in patients with a high clinical risk for APN. Sigmoidoscopy should be performed initially in patients with low clinical risk for APN followed by supplementary colonoscopy in those with high APN risk scores based on both clinical and sigmoidoscopic risk factors. This protocol detected APN in 22 of 34 APN+ patients (64.7%) with little increase in the endoscopy burden, whereas only 16 of 34 APN+ patients (47.1%) would be identified by initial sigmoidoscopy followed by colonoscopy only in cases with distal neoplasms. LIMITATIONS Retrospective design. CONCLUSION Our APN risk score model provides an algorithm for efficient screening of colorectal cancer by sigmoidoscopy and colonoscopy.

Impact of comorbidity on colorectal cancer screening cost-effectiveness study in diabetic populations. J Gen Intern Med 2012; 27:730-8.

Abstract
BACKGROUND Although comorbidity has been shown to affect the benefits and risks of colorectal cancer (CRC) screening, it has not been accounted for in prior cost-effectiveness analyses of CRC screening. OBJECTIVE To evaluate the impact of diagnosis of diabetes mellitus, a highly prevalent comorbidity in U.S. adults aged 50 and older, on health and economic outcomes of CRC screening. DESIGN Cost-effectiveness analysis using an integrated modeling framework. DATA SOURCES Derived from basic and epidemiologic studies, clinical trials, cancer registries, and a colonoscopy database. TARGET POPULATION U.S. 50-year-old population. TIME HORIZON Lifetime. PERSPECTIVE Costs are based on Medicare reimbursement rates. INTERVENTIONS Colonoscopy screening at ten-year intervals, beginning at age 50, and discontinued after age 50, 60, 70, 80 or death. OUTCOME MEASURES Health outcomes and cost effectiveness. RESULTS OF BASE-CASE ANALYSIS Diabetes diagnosis significantly affects cost-effectiveness of CRC screening. For the same CRC screening strategy, a person without diabetes at age 50 gained on average 0.07-0.13 life years more than a person diagnosed with diabetes at age 50 or younger. For a population of 1,000 patients diagnosed with diabetes at baseline, increasing stop age from 70 years to 80 years increased quality-adjusted life years (QALYs) gained by 0.3, with an incremental cost-effectiveness ratio of $206,671/QALY. The corresponding figures for 1,000 patients without diabetes are 2.3 QALYs and $46,957/QALY. RESULTS OF SENSITIVITY ANALYSIS Cost-effectiveness results are sensitive to cost of colonoscopy and adherence to colonoscopy screening. LIMITATIONS Results depend on accuracy of model assumptions. CONCLUSION Benefits of CRC screening differ substantially for patients with and without diabetes. Screening for CRC in patients diagnosed with diabetes at age 50 or younger is not cost-effective beyond age 70. Screening recommendations should be individualized based on the presence of comorbidities.

Abstract
BACKGROUND Obesity is associated with increased colon cancer mortality and lower rates of mammography and Pap testing. METHODS We conducted a systematic review to determine whether obesity is associated with lower rates of colon cancer screening. We searched the PubMed, CINAHL, and Cochrane Library databases. Two investigators reviewed citations, abstracts, and articles independently. Two investigators abstracted study information sequentially and evaluated quality independently using standardized forms. We included all studies in our qualitative syntheses. We used random effects meta-analyses to combine those studies providing screening results by the following body mass index (BMI) categories: Normal, 18.5-24.9 kg/m(2) (reference); overweight, 25-29.9 kg/m(2); class I obesity, 30-34.9 kg/m(2); class II obesity, 35-39.9 kg/m(2); and class III obesity, ≥ 40 kg/m(2). RESULTS Of 5,543 citations, we included 23 articles. Almost all studies were cross-sectional and ascertained BMI and screening through self-report. BMI was not associated with colon cancer screening overall. The subgroup of obese white women reported lower rates of colon cancer screening compared with those with a normal BMI with combined ORs (95% CI) of 0.87 (0.82-0.93), 0.80 (0.65-0.99), and 0.73 (0.58-0.94) for class I, II, and III obesity, respectively. Results were similar among white men with class II obesity. CONCLUSIONS Overall, BMI was not associated with colon cancer screening. Obese white men and women may be less likely to undergo colon cancer screening compared with those with a normal BMI. IMPACT Further investigation of this disparity may reduce the risk of obesity-related colon cancer death.

Abstract
PURPOSE To examine whether body mass index is associated with reduced colorectal cancer (CRC) screening in a large population of black and white adults. METHODS Cross-sectional data collected at baseline for 9,547 black men, 14,515 black women, 3,519 white men, and 7,245 white women aged 50-79 enrolled in the Southern Community Cohort Study from 2002 to 2009 were used to examine odds ratios (OR) with 95 % confidence intervals (CI) for the use of colonoscopy or sigmoidoscopy in relation to body mass index (BMI) categories (<18.5, 18.5-24.9 (referent), 25-29.9, 30-34.9, 35-39.9, and 40+ (extreme obesity), kg/m(2)) using logistic regression controlling for age, education, income, health insurance status, last physician visit, cigarette smoking, and alcohol consumption. RESULTS Increased BMI was not associated with reduced CRC screening among whites (OR (95 % CI) for BMI ≥ 40 = 1.02 (0.71-1.46) for white men and 0.99 (0.83-1.19) for white women), and odds of CRC screening were increased with high BMI among blacks (OR (95 % CI) for BMI ≥ 40 = 1.34 (1.03-1.74) for black men and 1.13 (0.98-1.29) for black women). Extreme obesity was associated with reduced odds of CRC screening only among white women in subgroup analyses limited to those with health insurance or income ≥$25,000/year. CONCLUSIONS Elevated BMI was not a deterrent to CRC screening overall in this population. In light of low overall screening rates for colorectal cancer nationally, efforts to increase screening in all individuals should remain the focus of public health initiatives.

Abstract
OBJECTIVES To investigate the association between proximal colonic neoplasia and distal lesions as a function of the lesion type. The extent to which health, demographic, and study characteristics moderate this association was also examined. DATA SOURCES Google Scholar, Web of Science, Scopus, and PubMed. STUDY ELIGIBILITY CRITERIA Studies allowing the calculation of OR of proximal neoplasia (PN) and proximal advanced neoplasia (PAN) for distal hyperplastic polyps (HP), nonadvanced adenomas (NAA), adenomas (AD), and advanced neoplasia (AN); also, studies for which the proportions of subjects with isolated (i.e., not accompanied by distal lesions) PN (IPN) and PAN (IPAN) over the total number of subjects with PN or PAN could be calculated. STUDY APPRAISAL AND SYNTHESIS METHODS Thirty-two studies were included for calculating OR between proximal neoplasia and distal lesions and 40 studies for proportions of IPN and IPAN. Subgroup analyses were conducted for presence of symptoms, prevalence of PN and PAN, age, proportion of males, geographic region, study design, and demarcation point. RESULTS The association between distal lesions and proximal neoplasia increased with the severity of the distal lesions. Odds of PN were higher in subjects with HP compared to subjects with a normal distal colon. Odds of PN and PAN were higher in subjects with NAA, AD, and AN than in subjects with a normal distal colon. PAN were more strongly associated with distal lesions in asymptomatic populations, in young populations, and in populations with a low prevalence of PAN. In approximately 60% of the subjects with PN and PAN, these neoplasia were isolated. LIMITATIONS The present results may be affected by publication bias and dichotomization in the subgroup analyses. Limitations related to the individual studies include self-selection, lesion misclassification and misses, and technological advances leading to changes in the detection of lesions during the time span of the included studies. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS All types of distal lesions are predictive of PN. All types of distal neoplasia are predictive of PAN. The association between distal lesions and proximal neoplasia increases with the severity of the distal lesion. The association between distal lesions and proximal advanced neoplasia is stronger in low-risk groups as compared to high-risk groups.

Abstract
Background. The literature on colorectal cancer (CRC) screening is contradictory regarding the impact of weight status on CRC screening. This study was intended to determine if CRC screening rates among 2005 National Health Interview Survey (NHIS) respondent racial/ethnic and gender subgroups were influenced by weight status. Methods. Univariable and multivariable logistic regression analyses were performed to determine if CRC screening use differed significantly among obese, overweight, and normal-weight individuals in race/ethnic and gender subgroups. Results. Multivariable analyses showed that CRC screening rates did not differ significantly for individuals within these subgroups who were obese or overweight as compared to their normal-weight peers. Conclusion. Weight status does not contribute to disparities in CRC screening in race/ethnicity and gender subgroups.

Abstract
BACKGROUND Increasing colorectal cancer screening (CRCS) is important for attaining the Healthy People 2020 goal of reducing CRC-related morbidity and mortality. Evaluating CRCS trends can help identify shifts in CRCS, and specific groups that might be targeted for CRCS. METHODS We utilized medical records to describe population-based adherence to average-risk CRCS guidelines from 1997 to 2008 in Olmsted County, MN. CRCS trends were analyzed overall and by gender, age, and adherence to screening mammography (women only). We also carried out an analysis to examine whether CRCS is being initiated at the recommended age of 50. RESULTS From 1997 to 2008, the size of the total eligible sample ranged from 20,585 to 21,468 people. CRCS increased from 22% to 65% for women and from 17% to 59% for men (P < 0.001 for both) between 1997 and 2008. CRCS among women current with mammography screening increased from 26% to 74%, and this group was more likely to be adherent to CRCS than all other subgroups analyzed (P < 0.001).The mean ages of screening initiation were stable throughout the study period, with a mean age of 55 years among both men and women in 2008. CONCLUSION Although overall CRCS tripled during the study period, there is still room for improvement. IMPACT Working to decrease the age at first screening, exploration of gender differences in screening behavior, and targeting women adherent to mammography but not to CRCS seem warranted.

Abstract
BACKGROUND The incidence of colorectal cancer following a normal colonoscopy in the Medicare population is not known. METHODS A 5% national sample of Medicare enrollees from 1996 to 2005 was used to identify patients undergoing complete colonoscopy. A colonoscopy not associated with any procedure (e.g., biopsy, polypectomy or fulguration) was defined as a negative colonoscopy. Patients with history of inflammatory bowel disease, colorectal cancer or death within 12 months of colonoscopy were excluded. A multivariable model was constructed to evaluate the factors associated with a new diagnosis of colorectal cancer in the period from 12 to 120 months following the negative colonoscopy. RESULTS Among 200,857 patients (mean age 74 years, 61% female, 92% White) with a negative colonoscopy, the incidence of colorectal cancer was 1.8 per 1,000 person-years. The incidence rate for matched follow-up periods decreased from 2.0/1,000 person-years for patients undergoing colonoscopy during 1996-2000 to 1.2/1,000 person years during 2001-2005. Multivariate analysis revealed a significant regional variation in the incidence of colorectal cancer following a negative colonoscopy. The incidence was higher in patients >85 years, males and patients who underwent a negative colonoscopy by a non-gastroenterologist or endoscopist in the lowest volume quartile. On stratified analyses, endoscopist volume was a significant predictor for non-gastroenterologists only. CONCLUSIONS The specialty and experience of the endoscopist are significant predictors of the incidence rate of colorectal cancer in Medicare patients with a negative colonoscopy.

DESIGN Cross-sectional, regression discontinuity. SETTING Canada and the US. PARTICIPANTS Canadian and American women of ages 30-60 and men of ages 40-60. INTERVENTIONS None. Main Outcomes Measures Mammography, prostate-specific antigen (PSA) and colorectal cancer test use within the past 2 years. METHODS We identify US and Canadian compliance with age screening information in a novel manner, by comparing test utilization rates of individuals who are immediately on either side of the guideline recommended initiation ages. RESULTS US mammography utilization within the last 2 years increased from 33% at age 39 to 48% at age 40 and 60% at age 41. US colorectal cancer test utilization, within the last 2 years, increased from 15% at age 49 to 18% at age 50 and 28% at age 51. US PSA utilization within the last 2 years increased from 37% at age 49 to 44% at age 50 and 54% at age 51. In Canada, mammography utilization within the last 2 years increased from 47% at age 49 to 57% at age 50 and 66% at age 51. CONCLUSION American and Canadian cancer screening utilization is generally consistent with each country's guideline recommendations regarding age. US and Canadian differences in screening due to guidelines can potentially explain cross-country differences in breast cancer mortality and affect interpretation of international comparisons of cancer statistics.

Abstract
BACKGROUND All relevant authorities recommend an interval of 10 years between normal screening colonoscopies. We assessed the timing of repeated colonoscopies after a negative screening colonoscopy finding in a population-based sample of Medicare patients. METHODS A 5% national sample of Medicare enrollees from 2000 through 2008 was used to identify average-risk patients undergoing screening colonoscopy between 2001 and 2003. Colonoscopy was classified as a negative screening examination finding if no indication other than screening were in the claims and if no biopsy, fulguration, or polypectomy was performed. Time to repeated colonoscopy was calculated. RESULTS Among 24,071 Medicare patients who had a negative screening colonoscopy finding in 2001 through 2003, 46.2% underwent a repeated examination in fewer than 7 years. In 42.5% of these patients (23.5% of the overall sample), there was no clear indication for the early repeated examination. In patients aged 75 to 79 years or 80 years or older at the time of the initial negative screening colonoscopy result, 45.6% and 32.9%, respectively, received a repeated examination within 7 years. In multivariable analyses, male sex, more comorbidities, and colonoscopy by a high-volume colonoscopist or in an office setting were associated with higher rates of early repeated colonoscopy without clear indication, while those 80 years or older had a reduced risk. There were also marked geographic variations, from less than 5% in some health referral regions to greater than 50% in others. CONCLUSIONS A large proportion of Medicare patients who undergo screening colonoscopy do so more frequently than recommended. Current Medicare regulations intending to limit reimbursement for screening colonoscopy to every 10 years would not appear to be effective.

Abstract
BACKGROUND This study examined the differential effects of physician supplies on colon cancer care in Ontario and California. The associations of physician supplies with colon cancer stage at diagnosis, receipt of surgery and adjuvant chemotherapy, and 5-year survival were observed within each country and compared between-country. METHODS Random samples of Ontario and California cancer registries provided 2,461 and 2,200 colon cancer cases that were diagnosed between 1996 and 2000, and followed until 2006. Both registries included data on the stage of disease at the time of diagnosis, receipt of cancer-directed surgery, receipt of adjuvant chemotherapy, and survival. Census tract-level data on low-income prevalence were, respectively, taken from 2001 and 2000 Canadian and United States population censuses. County-level primary care physician and gastroenterologist densities were computed for the same years. RESULTS Significant income-adjusted, gastroenterologist density threshold effects (2.0 or more vs. less than 2.0 per 100,000 inhabitants) were observed for early diagnosis (OR = 1.57) and 5-year survival (OR = 1.63) in Ontario, but not in California. Significant incremental threshold effects of primary care physician densities on chemotherapy receipt (8.0 and 9.0 or more per 10,000 inhabitants, respective ORs of 1.79 and 2.37) were also only observed in Ontario. CONCLUSIONS These colon cancer care findings support the theory that while personal economic resources are more predictive in America, community-level resources such as physician supplies are more predictive of health care access and effectiveness in Canada.

Abstract
The relationship between obesity and cancer screening varies by screening test, race, and gender. Most studies on cervical cancer screening found a negative association between increasing weight and screening, and this negative association was most consistent in white women. Recent literature on mammography reports no association with weight. However, some studies show a negative association in white, but not black, women. In contrast, obese/overweight men reported higher rates of prostate-specific antigen (PSA) testing. Comparison of prostate cancer screening, mammography, and Pap smears implies a gender difference in the relationship between screening behavior and weight. In colorectal cancer (CRC) screening, the relationship between weight and screening in men is inconsistent, while there is a trend towards lower CRC screening in higher weight women.

Abstract
OBJECTIVES We examined the differential effects of socioeconomic status on colon cancer care and survival in Toronto, Ontario, Canada, and San Francisco, California. METHODS We analyzed registry data for colon cancer patients from Ontario (n = 930) and California (n = 1014), diagnosed between 1996 and 2000 and followed until 2006, on stage, surgery, adjuvant chemotherapy, and survival. We obtained socioeconomic data for individuals' residences from population censuses. RESULTS Income was directly associated with lymph node evaluation, chemotherapy, and survival in San Francisco but not in Toronto. High-income persons had better survival rates in San Francisco than in Toronto. After adjustment for stage, survival was better for low-income residents of Toronto than for those of San Francisco. Middle- to low-income patients were more likely to receive indicated chemotherapy in Toronto than in San Francisco. CONCLUSIONS Socioeconomic factors appear to mediate colon cancer care in urban areas of the United States but not in Canada. Improvements are needed in screening, diagnostic investigations, and treatment access among low-income Americans.

Abstract
OBJECTIVE To determine if the relationship between obesity and usage of colorectal cancer (CRC) screening in women varies when stratifying by race. METHODS Using nationally representative data from the 2005 National Health Interview Survey, we examined the relationship between obesity and CRC screening for white and African-American women aged 50 and older. Screening usage variables indicated if a woman was up-to-date for any CRC screening test, colonoscopy, or FOBT. We used multivariable logistic regression models that included interaction terms to determine if race moderates the obesity-screening relationship. We also calculated adjusted up-to-date colonoscopy rates using direct standardization to model covariates. RESULTS The relationship between obesity and screening differed by race for any CRC screening test (P = 0.04 for interaction) and for colonoscopy (P = 0.01 for interaction), but not for FOBT. Obese white women had a lower adjusted colonoscopy rate (30.2%, 95% CI 25.9-34.8) than non-obese white women (39.1%, 95% CI 36.1-42.2). Obese African-American women, on the other hand, had a higher adjusted colonoscopy rate (41.2%, 95% CI 31.6-51.4) than their non-obese counterparts (35.6%, 95% CI 28.3-43.6). Overall, adjusted colonoscopy rates were lowest among obese white women. CONCLUSIONS Obesity is associated with lower CRC screening rates in white, but not African-American women.

Abstract
Obesity is a risk factor for colorectal cancer and adenomatous polyps. The increased prevalence of neoplasia coupled with the observation that obesity may be associated with a suboptimal bowel preparation may diminish the adequate detection of adenomas for obese who undergo colonoscopy. The colonic complications of obesity are reviewed in this article.

Abstract
BACKGROUND Lower GI endoscopy, such as colonoscopy or sigmoidoscopy, is thought to have a substantial impact on colorectal cancer incidence and mortality through detection and removal of precancerous lesions and early cancers. We aimed to review prevalence estimates of history of colonoscopy or sigmoidoscopy in the general population and to analyze recent trends. METHODS A systematic review of the medical literature, including MEDLINE (1966 to August 2008) and EMBASE (1980 to August 2008), was undertaken, supplemented by searches of the European Health Interview & Health Examination Surveys database and bibliographies. Detailed age-specific and sex-specific prevalence estimates from the United States were obtained from the Behavioral Risk Factor Surveillance System surveys 2002, 2004, and 2006. RESULTS The search yielded 55 studies that met our inclusion criteria. The majority of the reports (43) originated from the United States. Other countries of origin included Australia (2), Austria (2), Canada (5), France (1), Germany (1), and Greece (1). Estimates from the United States were generally increasing over time up to 56% (2006) for lifetime use of colonoscopy or sigmoidoscopy in people aged 50 years and older. Analysis of national survey data showed higher prevalences among men aged 55 years and older than for women of the same age. Prevalences were highest for people aged 70 to 79 years. CONCLUSION Data from outside the United States were extremely limited. Prevalence estimates from the United States indicate that a considerable and increasing proportion of the population at risk has had at least 1 colonoscopy or sigmoidoscopy in their lives, although differences between age and sex groups persist. Prevalences of previous colonoscopy or sigmoidoscopy need to be taken into account in the interpretation of time trends in, and variation across, populations of colorectal cancer incidence and mortality.

Abstract
OBJECTIVE Obstetrician/gynecologists (Ob/Gyn) and nurse practitioners (NP) are essential providers of primary and preventive care for their female patients. Therefore, colorectal cancer (CRC) screening should be part of their routine preventive practices. The purpose of our study is to evaluate the CRC screening practices of these providers. METHODS A self-administered survey was mailed to a national sample of 1130 Ob/Gyns and NPs to assess providers' demographics, current CRC screening practices, and familiarity with CRC guidelines. RESULTS Three hundred thirty-six providers (29.7%) returned our survey (54% Ob/Gyns and 46% NPs). Three fourths of providers routinely performed screening for CRC, compared with 95% for breast and cervical cancer. Routine CRC screening was more common among Ob/Gyns (87.2%) than NPs (61.7%) (p < 0.001). Slightly over half of providers correctly identified the recommended age to begin CRC screening for the average-risk patient, with no significant difference between provider types. Overall, Ob/Gyns scored higher than NPs on a series of questions assessing CRC screening (p < 0.03). Several provider factors were found to be significantly associated with screening practices, including practicing >10 years (p < 0.01), practicing in a multispecialty group (2.62 times more likely), and having an older patient population (p < 0.001). CONCLUSIONS Ob/Gyns and NPs underuse CRC screening compared with breast and cervical cancer screening and lack knowledge about appropriate use of CRC screening modalities. Opportunities to further educate Ob/Gyns and NPs should be sought to improve compliance with current CRC screening guidelines.

Abstract
BACKGROUND U.S. cancer screening guidelines communicate important information regarding the ages for which screening tests are appropriate. Little attention has been given to whether breast, colorectal and prostate cancer screening test use is responsive to guideline age information regarding the age of screening initiation. METHODS The 2006 Behavioral Risk Factor Social Survey and the 2003 National Health Interview Surveys were used to compute breast, colorectal and prostate cancer screening test rates by single year of age. Graphical and logistic regression analyses were used to compare screening rates for individuals close to and on either side of the guideline recommended screening initiation ages. RESULTS We identified large discrete shifts in the use of screening tests precisely at the ages where guidelines recommend that screening begin. Mammography screening in the last year increased from 22% [95% CI = 20, 25] at age 39 to 36% [95% CI = 33, 39] at age 40 and 47% [95% CI = 44, 51] at age 41. Adherence to the colorectal cancer screening guidelines within the last year increased from 18% [95% CI = 15, 22] at age 49 to 19% [95% CI = 15, 23] at age 50 and 34% [95% CI = 28, 39] at age 51. Prostate specific antigen screening in the last year increased from 28% [95% CI = 25, 31] at age 49 to 33% [95% CI = 29, 36] and 42% [95% CI = 38, 46] at ages 50 and 51. These results are robust to multivariate analyses that adjust for age, sex, income, education, marital status and health insurance status. CONCLUSION The results from this study suggest that cancer screening test utilization is consistent with guideline age information regarding the age of screening initiation. Screening test and adherence rates increased by approximately 100% at the breast and colorectal cancer guideline recommended ages compared to only a 50% increase in the screening test rate for prostate cancer screening. Since information regarding the age of cancer screening initiation varies across countries, results from this study also potentially have implications for cross-country comparisons of cancer incidence and survival statistics.

Abstract
BACKGROUND Provider recommendation of colorectal cancer (CRC) screening is an important predictor of screening in African Americans. Little is known about influences of screening in African Americans without provider recommendations. OBJECTIVES The objectives of this study were to test, using the biopsychosocial (BPS) model, the relative predictive strength for screening of variables grouped into biological, psychological and behavioral, and social system factors and to compare CRC screening predictors in African Americans with and without provider recommendations. METHODS Secondary analysis of the 2002 Maryland Cancer Survey data was done using (a) hierarchical logistic regression to examine the relative influence of factors on screening and (b) simultaneous logistic regression to examine predictors of screening in individuals with and without provider recommendations to screen. Factors included biological (age and gender), psychological and behavioral (mammogram, prostate specific antigen, body mass index, activity level, fruit and vegetable consumption, alcohol, smoking, and cancer perceptions), and social system (education, employment, insurance, and healthcare provider access). RESULTS The social system factor influenced CRC screening in the overall sample (n = 492). In African Americans with provider recommendations (n = 337), the very active were 2.43 (95% confidence interval [CI] = 1.11-5.28) times more likely to screen than were less active. Insured were 3.25 (95% CI = 1.14-9.31) times more likely to screen than were uninsured. In African Americans without provider recommendations (n = 155), 65- to 69-year-olds were 9.99 (95% CI = 2.31-43.32) times more likely to screen than were those 50- to 54-year-olds without screening. DISCUSSION The BPS model confirms social system factor strength in influencing CRC screening in African Americans. Identifying other social system variables that enhance healthcare provider access is critical to increase provider visits, which will generate recommendations and subsequent CRC screening.

Abstract
OBJECTIVE To compare the characteristics of people who utilize colorectal cancer screening tests with those who do not. SETTING Self-reported questionnaire data from 15,900 women and 14,953 men aged 50 or over who had never had colorectal cancer were taken from the 45 and Up Study cohort in Australia in 2006. METHODS A cross-sectional analysis of colorectal cancer test behaviour within the last five years by faecal occult blood test (FOBT), or by any test (FOBT, sigmoidoscopy or colonoscopy) was performed. RESULTS A total of 36.2% of participants reported colorectal cancer testing and 17.9% reported having a FOBT. Both FOBT and any testing were reduced significantly in groups with the following attributes compared with the remaining population; ages 50-59 and 80+; female; no family history of colorectal cancer; lower education; lower income; not speaking English at home; lack of private health insurance; not being retired; not living with a partner and not having other screening tests. Compared with other participants, test uptake was particularly low among current smokers (relative risk 0.76, 95% CI 0.71-0.80), sedentary participants (0.71, 95% CI 0.66-0.77), those without fruit (0.77, 95% CI 0.71-0.84) or vegetables (0.79, 95% CI 0.69-0.90) in their daily diet and those with a disability (0.91, 95% CI 0.85-0.97). Compared with participants from major cities, outer regional area participants were significantly more likely to report a FOBT (1.31, 95% CI 1.23-1.39) however participants in remote areas were significantly less likely to have had any colorectal cancer test (0.75, 95% CI 0.67-0.85). CONCLUSION Subgroups of the Australian population may require targeted intervention to ensure equity in colorectal cancer screening.

Abstract
OBJECTIVE We examined use of colorectal cancer (CRC) screening exam modalities among county health centers and private physician offices, where both were located in the same geographic area. METHODS We surveyed 500 county health center registrants and 570 private physician patients, aged 52-75 years. We administered telephone surveys during 2004 to examine relationships among sociodemographic characteristics; perceived barriers to screening with fecal occult blood test (FOBT), sigmoidoscopy, and colonoscopy; and self-reported receipt of each exam. RESULTS FOBT was more frequent among county health center registrants; sigmoidoscopy and colonoscopy were more frequent among private physician patients (p < 0.001). County health center registrants less frequently cited no physician recommendation as a barrier to FOBT, but more frequently cited no recommendation as a barrier to sigmoidoscopy and colonoscopy, compared with private physician patients (p < or = 0.02). Among county health center registrants, better health insurance coverage was associated with lower odds of FOBT and higher odds of screening endoscopy; perceived barriers were associated with lower odds of screening (p < 0.02). Among private physician patients, we noted an association between perceived barriers to screening and lower odds of any screening (p < 0.001). CONCLUSIONS Overall, CRC screening among county health center and private physician patient samples compared favorably with overall New York and U.S. rates. Although prior studies using national data suggested that screening rates were equivalent in county health center and private physician primary care settings, we found exam-specific differences in patient-reported screening endoscopy among our two patient samples. Understanding factors that contribute to differences in CRC screening between primary care settings is important for ensuring equal access to CRC screening options for all patients.

Abstract
BACKGROUND Self-selection may compromise cost-effectiveness of screening programs. We hypothesized that nonparticipants have generally higher morbidity and mortality than participants. METHODS A Swedish population-based random sample of 1,986 subjects ages 59 to 61 years was invited to sigmoidoscopy screening and followed up for 9 years by means of multiple record linkages to health and population registers. Gender-adjusted cancer incidence rate ratio (IRR) and overall and disease group-specific and mortality rate ratio (MRR) with 95% confidence intervals (95% CI) were estimated for nonparticipants relative to participants. Cancer and mortality rates were also estimated relative to the age-matched, gender-matched, and calendar period-matched Swedish population using standardized incidence ratios and standardized mortality ratios. RESULTS Thirty-nine percent participated. The incidence of colorectal cancer (IRR, 2.2; 95% CI, 0.8-5.9), other gastrointestinal cancer (IRR, 2.7; 95% CI, 0.6-12.8), lung cancer (IRR, 2.2; 95% CI, 0.8-5.9), and smoking-related cancer overall (IRR, 1.4; 95% CI, 0.7-2.5) tended to be increased among nonparticipants relative to participants. Standardized incidence ratios for most of the studied cancers tended to be >1.0 among nonparticipants and <1.0 among participants. Mortality from all causes (MRR, 2.4; 95% CI, 1.7-3.4), neoplastic diseases (MRR, 1.9; 95% CI, 1.1-3.5), gastrointestinal cancer (MRR, 4.7; 95% CI, 1.1-20.7), and circulatory diseases (MRR, 2.3; 95% CI, 1.2-4.2) was significantly higher among nonparticipants than among participants. Standardized mortality ratio for the studied outcomes tended to be increased among nonparticipants and was generally decreased among participants. CONCLUSION Individuals who might benefit most from screening are overrepresented among nonparticipants. This self-selection may attenuate the cost-effectiveness of screening programs on a population level.

Abstract
BACKGROUND Publicly-funded health centers serve disadvantaged populations who underuse colorectal cancer screening (CRC). Because physicians play a key role in patient adherence to screening, provider interventions within health center practices could improve the delivery/utilization of CRC screening. METHODS A 2-group study design was used with 4 pairs of health centers randomized to the intervention or control condition. The provider intervention featured academic detailing of the small practice groups, followed by a strategic planning session with the entire health center staff using SWOT analysis. The outcome measure of provider endoscopy referral/fecal occult blood test dispensing and/or completion of CRC screening was determined by medical record audit (n = 2224). The intervention effect was evaluated using generalized estimating equations. Pre-post intervention patient surveys (n = 281) were conducted. RESULTS Chart audits of the 1 year period before and after the intervention revealed a 16% increase from baseline in CRC screening referral/dispensing/completion among intervention centers, compared with a 4% increase among controls, odds ratio (OR) = 2.25 (1.67-3.04) P < 0.001. Intervention versus control health center patient self-reports of lack of physician recommendation as a reason for not having CRC screening declined from baseline to follow-up (P = 0.04). CONCLUSIONS Provider referrals/dispensing/completion of CRC screening within health centers was significantly improved and barriers reduced through a provider intervention combining continuing medical education with a team building strategic planning exercise.

Abstract
BACKGROUND African Americans (AAs) have low rates of colorectal cancer (CRC) screening. To the authors' knowledge, factors that influence their participation, especially individuals with a family history of CRC ("family history"), are not well understood. METHODS A secondary analysis of the 2002 Maryland Cancer Survey data examined predictors of risk-appropriate, timely CRC screening ("screening") in AAs with a family history and in individuals without a family history. Predictors that were evaluated included age, sex, family history, mammogram or prostate-specific antigen (PSA) screening, body mass index, activity, fruit/vegetable consumption, alcohol, smoking, perceived risk of cancer, education, employment, insurance, access to a healthcare provider, and healthcare provider recommendation of fecal occult blood test (FOBT) and/or sigmoidoscopy/colonoscopy. RESULTS In individuals without a family history of CRC (N = 492), recommendation for FOBT (odds ratio [OR] of 11.90; 95% confidence interval [95% CI], 6.84-20.71) and sigmoidoscopy/colonscopy (OR of 7.06; 95% CI, 4.11-12.14), moderate/vigorous activity (OR of 1.74; 95% CI, 1.06-2.28), and PSA screening history (OR of 2.68; 95% CI, 1.01-7.81) were found to be predictive of screening. In individuals with a family history (N = 88), recommendation for sigmoidoscopy/colonscopy (OR of 24.3; 95%, CI 5.30-111.34) and vigorous activity (OR of 5.21; 95% CI, 1.09-24.88) were found to be predictive of screening. However, family history did not predict screening when the analysis was controlled for age, education, and insurance. AAs who had a family history were less likely to screen compared with their white counterparts (N = 293) and compared with AAs who were at average risk for CRC (P < .05). CONCLUSIONS Regardless of family history, healthcare provider recommendation and activity level were important predictors of screening. Lower screening rates were observed in AAs who had a family history compared with individuals who did not. The authors believe that, for AAs who have a family history, further examination of barriers and facilitators to CRC screening within the cultural context is warranted.

Abstract
The literature examining obesity as a barrier to screening for breast, cervical, and colorectal cancer has not been evaluated systematically. With the increasing prevalence of obesity and its impact on cancer incidence and mortality, it is important to determine whether obesity is a barrier to screening so that cancers among women at increased risk because of their body size can be detected early or prevented entirely. On the basis of 32 relevant published studies (10 breast cancer studies, 14 cervical cancer studies, and 8 colorectal cancer studies), the authors reviewed the literature regarding associations between obesity and recommended screening tests for these cancer sites among women in the U.S. The most consistent associations between obesity and screening behavior were observed for cervical cancer. Most studies reported an inverse relation between decreased cervical cancer screening and increasing body size, and several studies reported that the association was more consistent among white women than among black women. For breast cancer, obesity was associated with decreased screening behavior among white women but not among black women. The literature regarding obesity and colorectal cancer screening adherence was mixed, with some studies reporting an inverse effect of body size on screening behavior and others reporting no effect. Overall, the results indicated that obesity most likely is a barrier to screening for breast and cervical cancers, particularly among white women; the evidence for colorectal cancer screening was inconclusive. Thus, efforts to identify barriers and increase screening for breast and cervical cancers may be targeted toward obese women, whereas outreach to all women should remain the objective for colorectal cancer screening programs.
