Background and Objectives: Disparities in esophageal cancer are well-established.The standard treatment for locally advanced esophageal cancer is chemoradiation followed by surgery. We sought to evaluate the association between socioeconomic factors, time to surgery, and patient outcomes.Methods: All patients ≥18 years old diagnosed with T2/3/4 or node-positive esophageal cancer between 2004 and 2016 and who underwent chemoradiation and esophagectomy in the National Cancer Database were included. Multivariable regression was used to assess the association between socioeconomic variables and time to surgery (grouped into <56, 56-84, and 85-112 days).Results: A total of 12 157 patients were included. Five-year overall survival was 39%, 35%, and 35% for the three groups examined. Postoperative 30-and 90-day mortality was increased in both the 56-84 days to surgery group (odds ratio [OR]:1.30 and 1.20, respectively) and the 85-112 days group (OR: 1.37 and 1.56, respectively) when compared to <56 days. Patients of a minority race, public insurance, or lower income were more likely to have a longer time to surgery.
Conclusion:Longer time to surgery is associated with increased postoperative mortality and is more common in patients with lower socioeconomic status. Further research exploring reasons for delays to esophagectomy among disadvantaged patients could help target interventions to reduce disparities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
