title: Endoscopic ultrasound-guided fine needle aspiration in esophageal cancer.
abstract: Esophageal cancer has a poor prognosis since it is often diagnosed in the symptomatic and incurable state. Accurate staging at initial diagnosis is imperative as it determines prognosis and influences treatment. Computed tomography (CT) scan is sensitive for identifying metastatic disease but is insensitive for detecting the extent of wall involvement or nodal disease. Endoscopic ultrasound (EUS) has emerged as a powerful tool in staging esophageal cancer with an impressive accuracy. Use of endoscopic ultrasound-guided fine needle aspiration as an adjunct further improves accuracy in nodal staging and allows for histologic confirmation. The impact of this invaluable staging modality in the management of esophageal cancer continues to grow.
