[Colorectal cancer screening programme in Aragon (Spain): preliminary results]

Abstract

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

Methods: 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".

Results: 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).

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