Geographic Variations in Demographics, Socioeconomic Status, and Stage at Diagnosis Among Hormone Receptor–positive Invasive Ductal Carcinoma: An NCDB Analysis (2004-2020)

Key Points

To examine how demographics and socioeconomic status affect stage at diagnosis in hormone receptor-positive invasive ductal carcinoma.
Analysis of data from the National Cancer Database (2004-2020)
Comparison of demographic factors and socioeconomic status
Assessment of stage at diagnosis and overall breast cancer outcomes
Significant variation in demographics and socioeconomic status observed among patients
Differences in stage at diagnosis linked to socioeconomic factors
Call for targeted interventions to address geographic disparities and improve outcomes

Abstract

Significant variation exists in the demographic and SES profile of patients with HR+ IDC, corresponding to differences in stage at diagnosis, and BC-related overall outcomes. These disparities likely reflect inequities in screening access, SES, and healthcare infrastructure, underscoring the need for region-specific public health strategies. Targeted regional interventions and equitable screening expansion are warranted to reduce geographic disparities and improve overall BC-related outcomes.
