ABSTRACT: Background
The advantages of endoscopic ultrasound (EUS) and computed tomography (CT)-positron emission tomography (PET) with respect to survival for esophageal cancer patients are unclear. This study aimed to assess the effects of EUS, CT-PET, and their combination on overall survival with respect to cases not receiving these procedures.Methods
Patients who were ≥66 years old when diagnosed with esophageal cancer were identified in the Surveillance, Epidemiology, and End Results-Medicare linked database. Cases were split into 4 analytic groups: EUS only (n = 318), CT-PET only (n = 853), EUS+CT-PET (n = 189), and no EUS or CT-PET (n = 2439). Survival times were estimated with the Kaplan-Meier method and were compared with the log-rank test for each group versus the no EUS o
