Persistent poverty and late-stage breast cancer diagnosis in the USA: impacts of rural residence, race, and time within Surveillance, Epidemiology, and End Results registries, 2004 to 2021.

ABSTRACT:

Background

County-level poverty is associated with higher rates of late-stage breast cancer (LSBC). The role of persistent poverty (> 20% residents in poverty for 30 + years) in breast cancer stage at diagnosis is unclear and may vary by rural/urban status, race, and over time.

Methods

We analyzed county-level data from the Surveillance, Epidemiology, and End Results Program for females (ages 20-74 years) with late-stage (regional and distant) breast cancer from 2017 to 2021 (excluding 2020). We estimated mean rate differences (RDs) in LSBC between persistently poor (n = 156) and non-persistently poor (n = 923) counties using multivariable linear regression models stratified by rural/urban status and race. We used Joinpoint regression analysis to estimate overall annual perc
