Five-year conditional relative survival up to 10 years post-diagnosis among adolescent and young adult breast cancer patients by age, stage, and receptor subtype.

ABSTRACT:

Background

Conditional relative survival (CRS), the probability of survival given that an individual has already survived a certain period post-diagnosis, is a more clinically relevant measure for long-term survival than standard relative survival (RS). This study aims to evaluate the 5-year CRS among adolescent and young adult (AYA) breast cancer patients by age, tumor stage, and receptor subtype to guide disclosure periods for insurance.

Methods

Data of all females aged 18-39 years and diagnosed with invasive breast cancer between 2003 and 2021 (n = 13,075) were obtained from The Netherlands Cancer Registry (NCR). The five-year CRS was calculated annually up to 10 years post-diagnosis using a hybrid analysis approach.

Results
