This is the current release of the guideline.

Each recommendation is followed by evidence grades (A-C) identifying the type of supporting evidence. Definitions of the evidence grades are presented at the end of the "Major Recommendations" field.

Recommendations

Endoscopic ultrasound-fine needle aspiration (EUS-FNA) is indicated for the evaluation of adenopathy and masses of the posterior mediastinum. It is the procedure-of-choice for tissue sampling of such lesions in the subcarinal, subaortic (aortopulmonary window), and periesophageal stations found on cross sectional imaging (computed tomography [CT], magnetic resonance imaging [MRI], or positron emission tomography [PET]). EUS-FNA should also be considered in the preoperative staging of patients with non-small cell lung cancer without definite adenopathy on cross sectional imaging.

Summary

• EUS-FNA is a safe and accurate method for obtaining a tissue diagnosis in patients with mediastinal adenopathy (B).
• In patients with non-small cell lung cancer, EUS-FNA is an accurate and cost-saving method for nodal staging in patients with documented posterior mediastinal adenopathy (B).
• EUS-FNA is the procedure-of-choice for the evaluation of posterior mediastinal nodes and masses seen on cross sectional imaging, and may have a role in the preoperative staging of patients with non-small cell lung cancer without mediastinal abnormalities on cross sectional imaging (C).
