Lo SH, Waller J, Wardle J, von Wagner C. Comparing barriers to colorectal cancer screening with barriers to breast and cervical screening: a population-based survey of screening-age women in Great Britain. J Med Screen. 2013;20(2):73–9. Available from: doi: 10.1177/0969141313492508.
Conclusion This was the first study to compare barriers to participation in organised screening programmes for CRC, breast and cervical cancer. Cancer screening tests share many barriers, but dislike of the test appears to be a stronger barrier to CRC screening. Women who are non-participants in more than one programme may have more global barriers to screening, such as cancer fatalism. The findings suggest that uptake of CRC screening could be improved by targeting the unpleasantness of stool sampling.

Conclusion:Socio-economic factors, GP-related factors, and history of previous FOBT influenced colonoscopy uptake after a positive FOBT. Interventions should target GPs and individuals performing their first screening FOBT and/or living in socio-economically deprived areas.British Journal of Cancer advance online publication. 29 August 2013; doi:10.1038/bjc.2013.476

CONCLUSIONS: The effect of screening with fecal occult-blood testing on colorectal-cancer mortality persists after 30 years but does not influence all-cause mortality. The sustained reduction in colorectal-cancer mortality supports the effect of polypectomy. (Funded by the Veterans Affairs Merit Review Award Program and others.).

Holme O, Bretthauer M, Fretheim A, Odgaard-Jensen J, Hoff G. Flexible sigmoidoscopy versus faecal occult blood testing for colorectal cancer screening in asymptomatic individuals. Cochrane database Syst Rev.2013;9:CD009259. doi: 10.1002/14651858.CD009259.pub2.
RESULTS: We identified nine studies comprising 338,467 individuals randomised to screening and 405,919 individuals to the control groups. Five studies compared flexible sigmoidoscopy to no screening and four studies compared repetitive guaiac-based FOBT (annually and biennially) to no screening. We did not consider that study risk of bias reduced our confidence in our results. We did not identify any studies comparing the two screening methods directly. When compared with no screening, colorectal cancer mortality was lower with flexible sigmoidoscopy (relative risk 0.72; 95% CI 0.65 to 0.79, high quality evidence) and FOBT (relative risk 0.86; 95% CI 0.80 to 0.92, high quality evidence).
