Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with a high suspicion of NSCLC and planned for an EBUS-TBNA procedure.

Probably not a fit

Patients who do not require surgical resection of thoracic lymph nodes or those in whom NSCLC is ultimately ruled out may not benefit from this study.

What this trial studies

This observational study aims to evaluate the effectiveness of analyzing the supernatant fluid from endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in diagnosing non-small cell lung cancer (NSCLC). The study focuses on patients with a high suspicion of NSCLC who have had negative EBUS-TBNA results. By utilizing next generation sequencing (NGS) on the supernatant, researchers hope to gather information about lymph node involvement in cases where traditional methods have failed. This approach could potentially reduce the need for more invasive surgical procedures.

Why it matters

Potential benefit: If successful, this method could provide a less invasive diagnostic option for patients with suspected lung cancer.

How similar studies have gone: While the use of liquid biopsy techniques is gaining popularity, this specific approach of analyzing EBUS-TBNA supernatant for NSCLC diagnosis is relatively novel and has not been extensively tested in prior studies.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* adult (age ≥18 years) patients with high suspicion for NSCLC with thoracic lymph nodes involvement (per clinical judgement and imaging studies), planned for an EBUS-TBNA procedure
* Subjects with negative EBUS-TBNA results (no evidence of lymph node involvement by tumor according to histology) who will require surgical resection of the thoracic lymph nodes will comprise the final study group

Exclusion Criteria:

1. Subjects unable or not willing to provide informed consent for study participation.
2. Subjects in whom NSCLC will ultimately be ruled out.
3. Subjects who will not require surgical resection of thoracic lymph nodes, or who will not undergo such procedure in our Medical Center for any reason
