This trial is testing a procedure called endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to help doctors better understand how far early-stage lung cancer has spread before you receive a specialized radiation treatment. The procedure uses a thin tube with an ultrasound camera to safely collect tiny samples from lymph nodes near your lungs. Doctors want to see if this procedure is more accurate than standard imaging scans at detecting whether cancer has spread to these lymph nodes.
Knowing whether cancer has spread to lymph nodes is critical for planning the right treatment. Standard imaging scans like CT and PET sometimes can't tell for certain whether lymph nodes contain cancer, which can lead to over- or under-treatment. This trial aims to see if this minimally invasive biopsy procedure gives doctors more reliable information to guide your care.

You will have a CT scan and PET scan to check your cancer stage. Then you'll visit the interventional suite at Toronto General Hospital, where a thoracic surgeon will perform the EBUS-TBNA procedure under local anesthesia with sedation to keep you comfortable. The surgeon will pass a thin, flexible tube through your mouth and airways to reach lymph nodes near your lungs and collect small tissue samples. After the procedure, if the results show cancer has not spread to the lymph nodes, you will proceed with SBRT radiation therapy. The research team will follow your medical records to track how well the treatment works.
