Estimated global cancer incidence in the oldest adults in 2018 and projections to 2050
Menée à partir des données de la base GLOBOCAN, cette étude estime l'incidence des cancers chez les personnes âgées d'au moins 80 ans en 2018 en fonction de la localisation géographique, présente les 5 cancers les plus fréquemment diagnostiqués par région et dans le monde chez les femmes et les hommes âgés de 65 à 79 ans et de 80 ans ou plus, puis propose une projection de l'incidence des cancers en 2050 chez les plus âgés
Using GLOBOCAN estimates, we describe the estimated cancer incidence among adults aged 80 years or older at the regional and global level in 2018, reporting the number of new cancer cases, and the truncated age-standardised incidence rates (per 100,000) for all cancer sites combined for this age group. We also presented the five most frequent cancers diagnosed by region and globally among females and males aged 65-79 years old and 80 years or older. We, finally, estimated the number of new cancer cases in 2050, the proportion of cases aged 80 years or older, and the proportional increase between 2018 and 2050 by region, by applying population projections to the 2018 incidence rates. In 2018, an estimated 2.3 million new cancer cases (excluding non-melanoma skin cancers) were aged 80 years or older worldwide (13% of all cancer cases), with large variation in the profiles at regional levels. Globally, breast, lung, and colon were the most common cancer sites diagnosed in the oldest females, while prostate, lung, and colon were most frequent in the oldest males. In 2050, an estimated 6.9 million new cancers will be diagnosed in adults aged 80 years or older worldwide (20.5% of all cancer cases). Due to the complexity of cancer management in the oldest patients, the expected increase will challenge healthcare systems worldwide, posing a tangible economic and social impact on families and society. It is time to consider the oldest population in cancer control policies. This article is protected by copyright. All rights reserved.
