New Type

A new type of faecal occult blood test, EZ-Detect™, has been evaluated in 404 patients presenting with symptoms suggestive of colorectal disease. The test avoids handling of stools and gives a result which patients can read themselves - factors which may increase patient compliance. In comparison with the Haemoccult™ test, EZ-Detect has the same sensiti-vity for blood in laboratory conditions. In clinical use 98% of patients expressed a preference for EZ-Detect but it detected significantly fewer patients with cancer than did Haemoccult (P = < 0.05). In its present form, this type of test would be unsuitable for population screening for colorectal cancer even if improved compliance is achieved.

Bowel Cancer Screening

Background: Colorectal cancer is the third most common cancer and the second leading cause of death worldwide. Bowel cancer screening helps prevent colon cancer by early detection of polyps, leading to efficient treatment and reduced mortality. Within Qatar, primary health facilities promote bowel screening by using the faecal occult blood test. However, the popularity and use of this test is still low. Aim: The aim of this literature review is to explore barriers related to colorectal cancer bowel screening using the faecal occult blood test in primary health care settings to facilitate colorectal cancer screening in Qatar. Method: Cronin’s five step framework for literature reviews was utilized for this paper. This review included nine articles that were peer-reviewed and published between 2009 and 2019. The nine articles were appraised by using the Mixed Methods Appraisal Tool. This tool has separate criteria to assess the quality of the qualitative, quantitative, and mixed-method studies. Result: Three main barriers to bowel cancer screening included knowledge deficit, personal beliefs and organizational barriers. Conclusion: The main barriers are related to the patients’ lack of knowledge and personal beliefs. Overcoming these barriers is essential to raising awareness about this issue among all nurses, physicians, and patients. It is necessary to involve stakeholders in order to mitigate barriers. Developing educational activities for healthcare professionals will provide information that they can share with patients to encourage screening and decrease the fear of the test. Developing a pamphlet to increase patient awareness will also encourage screening and work toward decreasing fear. Key words: faecal occult blood test, faecal immunochemical test, barriers

Over Time

Objectives Changes in the prevalence of faecal occult blood test positivity over time have not been previously reported, but could have important implications. This study examined the positivity of the initial guaiac faecal occult blood test, a surrogate marker for colorectal bleeding, in participants aged 50 in a national bowel screening programme. Methods Data from the Scottish Bowel Screening Programme were used to study the initial positivity of the guaiac faecal occult blood test between 2007 and 2017. Positive predictive values of the testing process for colorectal cancer and adenoma were assessed over the same time period. Results Across Scotland, the initial guaiac faecal occult blood test positivity increased from 4.1 to 10.8%. In NHS Grampian and NHS Fife, two of the three NHS Boards which began roll-out of screening in 2007, it increased from 4.0 to 10.9%. In the Scottish Bowel Screening Programme, the positive predictive value declined from 11.0 to 6.6% for colorectal cancer and increased from 31.6 to 39.8% for adenoma. Conclusions In the Scottish programme over a decade, initial guaiac faecal occult blood test positivity increased in participants aged 50. This may be associated with changes in lifestyle and might have implications for screening clinical outcomes, including positive predictive value.

Objectives Flexible sigmoidoscopy screening at around age 60 can reduce colorectal cancer incidence. Insufficient evidence exists on flexible sigmoidoscopy at age 60 in a population being offered biennial faecal occult blood test screening from age 50. This randomized controlled trial assessed if flexible sigmoidoscopy would be an effective adjunct to faecal occult blood test. Methods In the Scottish Bowel Screening Programme between June 2014 and December 2015, 51,769 individuals were randomized to be offered flexible sigmoidoscopy instead of faecal occult blood test at age 60 or to continue faecal occult blood test. Those not accepting flexible sigmoidoscopy and those with normal flexible sigmoidoscopy were offered faecal occult blood test. All with flexible sigmoidoscopy-detected neoplasia or a positive faecal occult blood test result were offered colonoscopy. Results Overall flexible sigmoidoscopy uptake was 17.8%, higher in men than women, and decreased with increasing deprivation (25.7% in the least to 9.2% in the most deprived quintile). In those who underwent flexible sigmoidoscopy, detection rate for colorectal cancer was 0.13%, for adenoma 7.27%, and for total neoplasia 7.40%. In those who underwent colonoscopy after a positive flexible sigmoidoscopy, detection rate for colorectal cancer was 0.28%, adenoma 8.66%, and total neoplasia 8.83%. On an intention to screen basis, there was no difference in colorectal cancer detection rate between the study and control groups. Adenoma and total neoplasia detection rate were significantly higher in the study group, with odds ratios of 5.95 (95%CI: 4.69–7.56) and 5.10 (95%CI: 4.09–6.35), respectively. Conclusions In a single screening round at age 60, there was low uptake and neoplasia detection rate. Flexible sigmoidoscopy detected significantly more neoplasia than faecal occult blood test alone.
