Colorectal Cancer Incidence in US Adults After Recommendations for Earlier Screening
Ce dossier présente deux études américaines, l'une analysant sur la période 2019-2023 l'évolution du recours au dépistage du cancer colorectal chez les adultes âgés de 45 à 49 ans, l'autre examinant, chez les adultes âgés de moins de 55 ans, l'évolution de l'incidence des cancers colorectaux après les recommandations 2018 de l'"American Cancer Society" et les recommandations 2021 de l'"US Preventive Services Task Force" préconisant d'abaisser à 45 ans l'âge d'inclusion dans le programme de dépistage du cancer colorectal
The recommended age to begin colorectal cancer (CRC) screening was lowered from 50 years to 45 years by the American Cancer Society in 2018 and the US Preventive Services Task Force (USPSTF) in 2021. CRC screening among adults aged 45 to 49 years increased during 2018-2022 in survey data and privately insured individuals. An accelerated increase in CRC incidence in ages 45 to 49 years was recently reported, but whether it reflects earlier detection through screening or increased disease occurrence remains unknown. This study addresses this gap by examining trends in CRC incidence among adults younger than 55 years.
