European guidelines for quality assurance in colorectal cancer screening and diagnosis: overview and introduction to the full supplement publication.

Population-based screening for early detection and treatment of colorectal cancer (CRC) and precursor lesions, using evidence-based methods, can be effective in populations with a significant burden of the disease provided the services are of high quality. Multidisciplinary, evidence-based guidelines for quality assurance in CRC screening and diagnosis have been developed by experts in a project co-financed by the European Union. The 450-page guidelines were published in book format by the European Commission in 2010.  They include 10 chapters and over 250 recommendations, individually graded according to the strength of the recommendation and the supporting evidence. Adoption of the recommendations can improve and maintain the quality and effectiveness of an entire screening process, including identification and invitation of the target population, diagnosis and management of the disease and appropriate surveillance in people with detected lesions. To make the principles, recommendations and standards in the guidelines known to a wider professional and scientific community and to facilitate their use in the scientific literature, the original content is presented in journal format in an open-access Supplement of Endoscopy. The editors have prepared the present overview to inform readers of the comprehensive scope and content of the guidelines.

Involving the community in cervical cancer prevention programs.

Underutilization of cervical cancer prevention services by women in the high-risk age group of 30-60 years can be attributed to health service factors (such as poor availability, poor accessibility, and poor quality of care provided), to women's lack of information, and to cultural and behavioral barriers. The Alliance for Cervical Cancer Prevention (ACCP) partners have been working to identify effective ways to increase women's voluntary participation in prevention programs by testing strategies of community involvement in developing countries. The ACCP experiences include developing community partnerships to listen to and learn from the community, thereby enhancing appropriateness of services; developing culturally appropriate messages and educational materials; making access to high-quality screening services easier; and identifying effective ways to encourage women and their partners to complete diagnosis and treatment regimens. Cervical cancer prevention programs that use these strategies are more likely to increase demand, ensure follow-through for treatment, and ultimately reduce disease burden.

Advocating for cervical cancer prevention.

Cervical cancer is a significant health problem among women in developing countries. Contributing to the cervical cancer health burden in many countries is a lack of understanding and political will to address the problem. Broad-based advocacy efforts that draw on research and program findings from developing-country settings are key to gaining program and policy support, as are cost-effectiveness analyses based on these findings. The Alliance for Cervical Cancer Prevention (ACCP) has undertaken advocacy efforts at the international, regional, national, and local levels to raise awareness and understanding of the problem (and workable solutions), galvanize funders and governments to take action, and engage local stakeholders in ensuring program success. ACCP experience demonstrates the role that evidence-based advocacy efforts play in the ultimate success of cervical cancer prevention programs, particularly when new screening and treatment approaches-and, ultimately, radically new approaches such as a human papillomavirus vaccine-are available.

Which socio-demographic factors are associated with participation in oral cancer screening in the developing world? Results from a population-based screening project in India.

BACKGROUND: This study examines socio-demographic determinants of participation in a population-based randomized controlled trial that proved that oral visual inspection was effective in reducing oral cancer mortality in high-risk individuals in India. METHODS: Multivariate logistic regression was used to establish socio-demographic characteristics of participants versus non-participants in the intervention arm. Compliance with referral was analysed according to the socio-demographic characteristics of screen-positives. RESULTS: Of 96,517 eligible subjects, 87,655 were screened, 8688 individuals never received the invitation and 174 refused screening. Compared to the non-screened, a higher proportion of screened individuals were women (OR=4.51; CI: 4.28-4.75), lived in better housing (OR=1.35; CI: 1.25-1.41), had television/radio (OR=1.50; CI: 1.43-1.58) and were tobacco and alcohol users (OR=2.75; CI: 2.57-2.95). Being 65 and older decreased the chances of screening (OR=0.39; CI: 0.37-0.42), as well as living in high-size households (OR=0.73; CI: 0.68-0.78). Sixty-three percent of 5143 screen-positives complied with referral. Controlling for all other factors, individuals older than 44, and those with more advanced lesions were more likely to comply with referral (p<0.001). Individuals living in better housing were less likely to comply with referral (OR=0.79; CI: 0.65-0.95). CONCLUSIONS: In summary, adequate coverage can be obtained in population-based oral screening in developing countries. The study underscores the important role of patient-provider communication in assuring high compliance with referral.
