BackgroundReceipt of guideline-concordant treatment (GCT) is associated with improved prognosis in foregut cancers. Studies show that patients living in areas of high neighborhood deprivation have worse healthcare outcomes; however, its effect on GCT in foregut cancers has not been evaluated. We studied the impact of the area deprivation index (ADI) as a barrier to GCT.Study DesignA single-institution retrospective review of 498 foregut cancer patients (gastric, pancreatic, and hepatobiliary adenocarcinoma) from 2018 to 2022 was performed. GCT was defined based on National Comprehensive Cancer Network guidelines. ADI, a validated measure of neighborhood disadvantage was divided into terciles (low, medium, and high) with high ADI indicating the most disadvantage.ResultsOf 498 patients, 328 (66%) received GCT: 66%, 72%, and 59% in pancreatic, gastric, and hepatobiliary cancers, respectively. Median (interquartile range) time from symptoms to workup was 6 (3 to 13) weeks, from diagnosis to oncology appointment was 4 (1 to 10) weeks, and from oncology appointment to treatment was 4 (2 to 10) weeks. Forty-six percent were diagnosed in the emergency department. On multivariable analyses, age 75 years or older (odds ratio [OR] 0.39 [95% CI 0.18 to 0.87]), Black race (OR 0.52 [95% CI 0.31 to 0.86]), high ADI (OR 0.25 (95% CI 0.14 to 0.48]), 6 weeks or more from symptoms to workup (OR 0.44 [95% CI 0.27 to 0.73]), 4 weeks or more from diagnosis to oncology appointment (OR 0.76 [95% CI 0.46 to 0.93]), and 4 weeks or more from oncology appointment to treatment (OR 0.63 [95% CI 0.36 to 0.98]) were independently associated with nonreceipt of GCT.ConclusionsResidence in an area of high deprivation predicts nonreceipt of GCT. This is due to multiple individual- and system-level barriers. Identifying these barriers and developing effective interventions, including community outreach and collaboration, leveraging telehealth, and increasing oncologic expertise in underserved areas, may improve access to GCT.Copyright © 2024 by the American College of Surgeons.
