Overview
This study will investigate the role of sampling suspicious chest lymph nodes with a procedure called endobronchial ultrasound-guided transbronchial fine needle aspiration (EBUS-TFNA) or transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) in patients planned to receive radical dose radiation.
This study will use Stereotactic Ablative Radiotherapy (SABR) for treatment methods. SABR is a newer radiation treatment that delivers high-dose, precise radiation to small tumors and can be delivered more accurately than with older radiation treatment methods. It is considered a standard treatment for small lung cancers, and select cancers that have spread to the brain.
The purpose of this study is to compare if the lymph node sampling procedure is valuable for determining the extend of nodal disease in metastatic Non-Small Cell Lung Cancer (NSCLC) compared to imaging alone.
Eligibility
Inclusion Criteria:

- Patient has undergone staging investigations less than 3 months prior to
registration.

- Pathologic confirmation of NSCLC
Exclusion Criteria:
- Contraindication to Endobronchial Ultrasound (EBUS) / Endoscopic Ultrasound (EUS)
- Unable to provide consent for EBUS/EUS
