Five-year experience of organized colorectal cancer screening in a Swedish population – increased compliance with age, female gender, and subsequent screening round
Menée auprès de plus de 200 000 personnes invitées entre 2008 et 2012 à participer à un programme biennal de dépistage du cancer colorectal comportant un test de recherche de sang occulte dans les selles et, si le résultat est positif, une coloscopie, cette étude suédoise évalue, en fonction de l'âge et du sexe, l'évolution du taux de participation
Objective : To evaluate compliance by age, gender, and screening round in the population based Stockholm/Gotland colorectal cancer screening programme.
Methods : All individuals aged between 60 and 69 living in the counties of Stockholm and Gotland (Sweden) have, since 2008, successively been included in a colorectal cancer screening programme using biennial faecal occult blood tests (Hemoccult®). Personal invitations including test kits have been sent to home addresses, and individuals with a positive test result have been called to a defined clinic for an assessment colonoscopy. Descriptive statistics have been used to evaluate different aspects of compliance.
Results : Over the five-year period 2008–2012, more than 200,000 individuals from nine different birth cohorts have been invited, with a compliance rate of approximately 60%, which increased by age, female gender, and subsequent screening round. In total, 4,300 individuals (2.1%) with positive tests were referred to assessment colonoscopy, where 213 colorectal cancers were diagnosed. The compliance with the follow-up colonoscopies varied by year, and ranged from 85.6–92.4%.
Conclusion : The strong organization of the programme contributed to a high compliance rate, that increased by screening round. The lower participation rate among men and among individuals at younger ages needs further attention.
