Factors determining the quality of screening colonoscopy: a prospective study on adenoma detection rates, from 12 134 examinations (Berlin colonoscopy project 3, BECOP-3). Gut 2013 February 01;62(2):236-241. DOI:10.1136/gutjnl-2011-300167.

Conclusions The outcome quality of screening colonoscopies is mainly influenced by individual colonoscopist factors (ie, CME activities) and instrument quality.

Summary A difference between colorectal cancer screening and screening for most other types of cancer is that various screening methods are available. A choice between screening methods is common in the USA. Most European programmes currently offer a single screening method, since it is recommended that only screening strategies with sufficient evidence for a reduction in colorectal cancer mortality are introduced. Faecal occult blood testing is widely accepted in Europe, and evidence on the effectiveness of flexible sigmoidoscopy is increasing. The availability of multiple effective screening options warrants deliberation on whether individuals should be given a choice between strategies. In this Personal View, we present arguments in favour and against offering a choice of screening strategies, together with the evidence substantiating these views. We also focus on screening invitees' autonomy, which is a crucial parameter in the debate.

Ann Intern Med 2012 Dec 18;157(12):856-864. DOI:10.7326/0003-4819-157-12-201212180-00005; 10.7326/0003-4819-157-12-201212180-00005. PMID:23247939.

CONCLUSION: Application of the U.K. guidelines in the United States could identify a subset of high-risk patients who may warrant a 1-year clearing colonoscopy without substantially increasing rates of colonoscopy. PRIMARY FUNDING SOURCE: European Union Public Health Programme.

Outcomes and cost evaluation of the first two rounds of a colorectal cancer screening program based on immunochemical fecal occult blood test in northern Italy. Endoscopy 2013 Jan;45(1):27-34. DOI:10.1055/s-0032-1325800; 10.1055/s-0032-1325800. PMID:23254404.

Conclusions: Compliance and diagnostic yield of i-FOBT screening were satisfactory. Most detected cancers were at a very early stage. Program costs were reasonable and did not increase with repeat screening. Screening could contribute to decreasing the cost of CRC care by improving the stage at diagnosis.

Simulation modeling is extensively applied to CT colonography (CTC) to define its long-term efficacy and cost-effectiveness for colorectal cancer (CRC) screening. CTC is effective in reducing CRC incidence and mortality (40%-77% and 58%-84%, respectively). Several factors may explain this variability. CTC is cost-effective compared with no screening, indicating that it represents an attractive test noncompliance with the available options. CTC needs to achieve a higher attendance rate or cost less than colonoscopy to be cost-effective relative to colonoscopy. Fortunately, both conditions appear to be achievable if CTC becomes a widely utilized and reimbursed screening tool.

DOI:10.1038/bjc.2012.512; PMID:23175148. PMCID:PMC3516693.

Conclusion:Most British adults want full information on risks and benefits of screening but they also want a recommendation from an authoritative source. An 'expert' view may be an important part of autonomous health decision-making.

A systematic review and meta-analysis of randomized trials conducted by B. Joseph Elmunzer and colleagues reports that that flexible sigmoidoscopy-based screening reduces the incidence of colorectal cancer in average-risk patients, as compared to usual care or no screening.

Conclusion: Compared with the currently recommended strategy of continuing colonoscopy every 10 years after an initial negative examination, rescreening at age 60 years with annual HSFOBT, annual FIT, or CTC every 5 years provides approximately the same benefit in life-years with fewer complications at a lower cost. Therefore, it is reasonable to use other methods to rescreen persons with negative colonoscopy results.Primary Funding Source: National Cancer Institute.

RESULTS: During an 18month period (July 2007-December 2008) 382,792 FOBT tests (in 325,851 people) were performed by the target population, of them 85% Jews and 15% Arabs. Seven hundred and eighteen colorectal cancers and 2652 adenomas were detected. The overall test positivity rate in repeatedly-tested people was 4.2%. The overall detection rate of colorectal cancer in the subsequent tests was 1.7/1000 reflecting 91% of the expected period-incidenc.

In conclusion, the ContinueFOBT_long strategy was advantageous regarding both clinical benefit and required resources. Specifying an appropriate management strategy for individuals with a prior fpFOBT may substantially reduce required resources within a FOBT-based CRC screening program without limiting its effectiveness.Nota bilbiogràfica

Resumen El cáncer colorrectal es una de las neoplasias que más puede beneficiarse de medidas preventivas, en especial del cribado. Para ello se dispone de diversas estrategias coste-efectivas: la detección de sangre oculta en heces mediante pruebas químicas (guayaco) o inmunoló¦gicas, y la realización de pruebas endoscópicas como la sigmoidoscopia flexible o la colonoscopia. En el presente artí¡culo se revisan las comunicaciones más relevantes presentadas en el congreso anual de la American Gastroenterological Association, celebrado en San Diego en mayo de 2012, en relación con el cribado del cáncer colorrectal, haciendo especial hincapié en su efectividad, por lo que respecta a la reducción de la incidencia y/o la mortalidad asociada a esta neoplasia.

Conclusions: Strategies which combine different screening modalities may provide greater clinical and economic benefits. The collection of comprehensive screening data using a uniform format will enable comparative analysis across screening programmes in different countries, will improve our understanding of the disease and will allow identification of optimal screening modalities
