SOLE LLOP, Mª Esther et al. Colorectal cancer screening programme in Aragon (Spain): preliminary results. Gac Sanit [online]. 2018, vol.32, n.6, pp.559-562. ISSN 0213-9111.


To describe preliminary findings from the colorectal cancer screening programme in Aragon (Spain) to evaluate its implementation.


We have collected data from the first year of the program (2014) based on faecal occult blood immunochemical (FOBTi) test in patients 60-69 years old. We report “indicators” defined by the “Red Nacional de Cribado”.


Invited population after exclusions: 12,518. Program participation rate: 45.28% (95%CI: 44.41-46.15). Inadequate tests: 0.21% (95%CI: 0.12-0.37); positive FOBTi test 10.75% (95%CI: 9.97-11.58) and colonoscopy acceptance 95.07% (95%CI: 93.04-96.52). Colonoscopy was appropriate and complete in 97.58% (95%CI: 95.98-98.55) of cases. The high- and low-risk adenoma detection rates were 14.7‰ (95%CI: 11.9-18.2) and 5.55‰ (95%CI: 3.9-7.8) respectively. The positive predictive value for any adenoma was 58.55% (95%CI: 54.49-62.49) and for invasive cancer was 5.36% (95%CI: 3.8-7.51).


The indicator analysis of the ongoing programme suggests the programme is being implemented correctly in our community.
