Sampling chest lymph nodes in patients with advanced lung cancer before radiation treatment

Endoscopic Nodal Staging in Oligometastatic Non-small Cell Lung Cancer (NSCLC) Being Treated With Stereotactic Ablative Radiotherapy (ENDO-SABR)

Not applicable Interventional London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's · NCT04852588

This study is testing if checking lymph nodes in the chest with special needles helps doctors better understand lung cancer in patients before they receive targeted radiation treatment.

What this trial studies

This study investigates the effectiveness of sampling suspicious chest lymph nodes using endobronchial ultrasound-guided transbronchial fine needle aspiration (EBUS-TFNA) or transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) in patients with oligometastatic non-small cell lung cancer (NSCLC) who are set to receive radical dose radiation. The research aims to determine if these sampling procedures provide valuable information about the extent of nodal disease compared to imaging alone. The treatment approach involves Stereotactic Ablative Radiotherapy (SABR), which delivers high-dose, precise radiation to small tumors. This study is crucial for understanding the role of lymph node assessment in the management of advanced lung cancer.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with oligometastatic non-small cell lung cancer and a good performance status.

Not a fit: Patients who have contraindications to endobronchial procedures or those with extensive metastatic disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance treatment planning and outcomes for patients with advanced lung cancer by providing more accurate staging information.

How similar studies have performed: Other studies have shown promise in using similar lymph node sampling techniques in cancer management, indicating potential for success in this approach.
