ABSTRACT Colorectal cancer screening reduces colorectal cancer incidence and mortality. This population-based study was conducted to evaluate (i) the association between subject factors and colorectal screening participation and (ii) the lifetime prevalence of colorectal screening among the general population of Ontario, Canada. Population-based controls were recruited by the Ontario Familial Colorectal Cancer Registry during 1998-2000. The 1944 persons completed an epidemiologic questionnaire. Descriptive statistics were computed and step-wise multivariate logistic regression was used to estimate odds ratios and 95% confidence intervals. Overall, 23% of persons greater than 50 years of age reported ever having had colorectal cancer screening; 17% reported fecal occult blood test (FOBT), 6% sigmoidoscopy, and 4% colonoscopy. Family history of colorectal cancer, increased age, higher household income, and use of hormone replacement therapy (among women) were all significantly associated with ever having had colorectal cancer screening. The low prevalence of colorectal cancer screening among the target population suggests the need for an increased awareness of the public health importance of colorectal cancer screening.

    ABSTRACT: Compared with the general population, first-degree relatives (FDRs) of colorectal cancer (CRC) patients have a two-fold to four-fold higher risk of developing CRC. Little data is available regarding communication between doctors and CRC patients about risk to FDRs. We aimed to evaluate CRC patients' knowledge of FDRs' increased CRC risk, and FDRs' knowledge of this risk and adherence to CRC screening. In this retrospective, single-center, population-based observational study, patients aged 18-80 years who underwent surgery for CRC between January 2005 and May 2010 were asked to complete a questionnaire. A questionnaire sent to the patients' FDRs (siblings and children) asked whether they had been advised to undergo any CRC screening examination, whether they had done so, and if so, when initiated and by whom. Main outcome measurements were: CRC patients' and their FDRs' information status regarding the FDRs' increased CRC risk and screening status. Of 343 index patients (390 contacted, 47 deceased/moved), 134 replied to the survey (39.1% response rate). Among index patients, 82.1% (110/134) were informed about FDRs' increased CRC risk. This information was provided mainly by gastroenterologists and general practitioners (65.7 and 28.4%, respectively). Among FDRs, 85.1% (143/168) were informed about their increased CRC risk, but 69% did not undergo a screening colonoscopy. Among the FDRs more than 50 years of age, 40.8% did not undergo a screening colonoscopy. In Switzerland, CRC patients and their FDRs are well informed about FDRs' increased CRC risk. However, the majority of FDRs do not undergo the recommended CRC screening.

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

    ABSTRACT: Objective: To evaluate compliance by age, gender, and screening round in the population based Stockholm/Gotland colorectal cancer screening programme. Methods: All individuals aged between 60 and 69 living in the counties of Stockholm and Gotland (Sweden) have, since 2008, successively been included in a colorectal cancer screening programme using biennial faecal occult blood tests (Hemoccult (R)). Personal invitations including test kits have been sent to home addresses, and individuals with a positive test result have been called to a defined clinic for an assessment colonoscopy. Descriptive statistics have been used to evaluate different aspects of compliance. Results: Over the five-year period 2008-2012, more than 200,000 individuals from nine different birth cohorts have been invited, with a compliance rate of approximately 60%, which increased by age, female gender, and subsequent screening round. In total, 4,300 individuals (2.1%) with positive tests were referred to assessment colonoscopy, where 213 colorectal cancers were diagnosed. The compliance with the follow-up colonoscopies varied by year, and ranged from 85.6-92.4%. Conclusion: The strong organization of the programme contributed to a high compliance rate, that increased by screening round. The lower participation rate among men and among individuals at younger ages needs further attention.
