Younger Adults, Earlier Screening—What We Are Learning About Colorectal Cancer and What Comes Next
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 incidence of colorectal cancer has increased among younger adults (18-49 years) since the early 1990s, a well-documented trend in early-onset colorectal cancer observed in the US and worldwide. In response, the American Cancer Society in 2018 and the US Preventive Services Task Force in 2021 revised their recommendations to begin average-risk screening at age 45 years instead of age 50 years. Although initially met with skepticism, these recommendations raised important questions. How will nearly 45 million US adults newly eligible for screening be reached? Will expanding eligibility to younger adults divert resources from and compromise progress made in screening older adults? And, ultimately, what will be the effect on population-level outcomes?
