Gender-specific cut-offs in colorectal cancer screening with FIT: Increased compliance and equal positivity rate:
2019
ObjectiveUsing quantitative Faecal Immunochemical Test (FIT) in colorectal cancer screening enables adjustment of the cut-off for a positive test. As men have higher stool blood levels and higher prevalence of colorectal neoplasia, different cut-off levels can be chosen for men and women. We evaluated participation and positivity rates switching from guaiac-based faecal occult blood test (gFOBT) (Hemoccult®) to FIT (OC-Sensor), using gender-specific cut-offs.MethodsThe colorectal cancer screening programme of Stockholm-Gotland, Sweden, started in 2008 and invited individuals aged 60–69 to biennial testing using gFOBT. From 1 October 2015 the test was switched to FIT, with positivity cut-offs of 40 (200) and 80 (400) µg Hb/g (ng/mL) faeces for women and men, respectively. The first year was evaluated for compliance and positivity, number of reminders and incorrect/inadequate tests, compared with gFOBT in the preceding 12-month period.ResultsThere were 127,030 and 87,269 individuals invited to screening wit...
