Transesophageal Ultrasound-Guided FNA for Staging Extrathoracic Tumors: Abstract and Introduction

Transesophageal Ultrasound-Guided FNA for Staging Extrathoracic Tumors: Abstract and Introduction

Several extrathoracic tumors metastasize to the mediastinum. Mediastinoscopy is the standard method to obtain tissue proof of mediastinal spread, but drawbacks are its invasiveness, requirement for general anesthesia and costs. Transesophageal endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is indicated in lung cancer staging guidelines as a minimally invasive alternative for surgical staging. The diagnostic values in patients with suspected mediastinal metastases and various (previous) extrathoracic malignancies were assessed.
