The Impact of Economic Status on Cause-Specific Survival in Patients with Esophageal Adenocarcinoma in the United States: A Retrospective Analysis.

Objective: This study aims to evaluate the impact of economic status on the cause-specific survival (CSS) of patients with esophageal adenocarcinoma (EAC).

Methods: Using propensity score matching (PSM), we analyzed data from 4676 patients with EAC, categorized into low household income (LHI) and high household income (HHI), sourced from the Surveillance, Epidemiology, and End Results database. Significant pre-PSM differences in age, gender, race, and tumor stage (T stage) were observed, necessitating PSM adjustment.
