OBJECTIVES: The efficacy of endoscopic ultrasound (EUS) for evaluating mediastinal adenopathy in lung cancer is nowadays proven. However, its accuracy for detection of malignant pleural effusion per se has not been yet investigated. Herein we report our experience with EUS for detecting pleural effusion during the staging procedure of non-small cell lung cancer (NSCLC) patients. METHODS: Between January 2009 and December 2011, we performed endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) on 92 selected NSCLC patients to evaluate the T and N factors and to acquire bioptic material and when this was detected, to sample the pleural effusion. RESULTS: In 10 patients (8 males and 2 females, mean age 66.9±9.2 years) a pleural effusion was detected and sampled. In 7 out of the 10 cases, the cytological examination of the fluid obtained by EUS-FNA tested positive for malignant cells, thereby upgrading the case to Stage IV, irrespective of T and N statuses. In 3 cases the cytology on the EUS-FNA material was proven to be negative for malignancy thereby allowing patients to be treated with curative intent without further delay. CONCLUSIONS: EUS-FNA of the pleural fluid is a safe and simple procedure. Our data, albeit stemming from a limited study population, show that it can be efficient in selected NSCLC cases for obtaining useful material and information with significant impact on the staging and, therefore, on the planning of the optimum therapeutic strategy.
