Prevalence of cancer survivors in the United States

Menée à l'aide d'une projection et de données statistiques et des registres américains des cancers, cette étude analyse les tendances de la survie à long terme des patients ayant des antécédents de cancer et les conséquences en matière de santé publique

Résumé en anglais

With aging of the population and improvements in diagnosis, treatment, and supportive care, the number of cancer survivors in the United States (US) has increased; updated prevalence estimates are needed.Cancer prevalence on January 1, 2022 was estimated using the Prevalence Incidence Approach Model, utilizing incidence, survival, and mortality. Prevalence by age decade, sex, and time from diagnosis were calculated. The percentage of cancer survivors in the projected US population by age and sex was calculated as the ratio of the sex-specific projected prevalence to the sex-specific projected US population.There were an estimated 18.1 million US cancer survivors as of January 1, 2022. From 2022 to 2030, the number of US cancer survivors is projected to increase to 21.6 million; by 2040, the number is projected to be 26 million. Long-term survivors are highly prevalent; in 2022, 70% of cancer survivors survived 5 years or more after diagnosis, and 11% of cancer survivors survived 25 years or more after diagnosis. Among all US females aged 40-54, 3.6% were cancer survivors; among females aged 65-74, 14.5% were cancer survivors; among females aged 85 and older, 36.4% were cancer survivors. Among all US males aged 40-54, 2.1% were cancer survivors; among males aged 65-74, 16% were cancer survivors; among those aged 85 and older, 48.3% were cancer survivors.Cancer survivors are growing in number. In the US, most cancer survivors are long-term and very long-term survivors, representing a significant proportion of the US population.
