Abstract

Background and Aims. EUS-FNA is an accurate and safe technique to biopsy mediastinal lymph nodes. However, there are few data pertaining to the role of EUS-FNA to biopsy central lung masses. The aim of the study was to assess the diagnostic yield and safety of EUS-FNA of indeterminate central mediastinal lung masses. Methods. Design: Retrospective review of a prospectively maintained database; noncomparative. Setting: Tertiary referral center. From 10-2004 to 12-2010, all patients with a lung mass located within proximity to the esophagus were referred for EUS-FNA. Main Outcome Measurement: EUS-FNA diagnostic accuracy and safety. Results. 73 consecutive patients were included. EUS allowed detection in 62 85% patients with lack of visualization prohibiting FNA in 11 patients. Among sampled lesions, one patient 1-62 = 1.6% had a benign lung mass hamartoma, while the remaining 61 patients 61-62 = 98.4% had a malignant mass primary lung cancer: 55-61 = 90%; lung metastasis: 6-61 = 10%. The sensitivity, specificity, and accuracy of EUS-FNA were 96.7%, 100%, and 96.7%, respectively. The sensitivity was 80.8% when considering nonvisualized masses. One patient developed a pneumothorax 1-62 = 1.6%. Conclusions. EUS-FNA appears to be an accurate and safe technique for tissue diagnosis of central mediastinal lung masses.
