NCT05164445

Brief Summary

This study is designed to evaluate complications, specificity, diagnostic yield of radial endobronchial ultrasound guided transbronchial cryobiopsy and transbronchial forceps biopsy with fluoroscopy in the diagnosis of peripheral pulmonary lesion; the interplay between non-small-cell lung cancer associated-bacteria along the gut-lung axis and immune response in the cancer microenvironment.

ACTIVE COMPARATOR

Patients, whose transbronchial forceps biopsy and transbronchial cryobiopsy were performed as well

Diagnostic Test: Transbronchial forceps biopsy+Transbronchial cryobiopsy

Interventions

All patients with peripheral lung lesion suspected of lung cancer detected on the chest computed tomography (CT) and mini probe endobronchial ultrasound (RP-EBUS) scans were enrolled. Transbronchial forceps biopsy (TBFB) was performed for all these patients.

Transbronchial forceps biopsy

All patients with peripheral lung lesion suspected of lung cancer detected on the chest computed tomography (CT) and RP-EBUS scans were enrolled. TBFB was performed for all these patients. In addition, all of these patients, with no contraindications, underwent transbronchial cryobiopsy (TBCB)

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • patients with peripheral lung lesion suspected of lung cancer detected on the chest computed tomography (CT) and RP-EBUS scans
  • Control group - patients without non-small cell lung cancer
  • Written (signed) Informed Consent to participate in the study

You may not qualify if:

  • severe hypoxemia (partial pressure of oxygen (pO2)\< 60 mmHg) or hypercapnia (carbon dioxide partial pressure (pCO2)\> 50 mmHg),
  • bleeding disorders
  • The diffusing capacity for carbon monoxide (DLCOc)\< 35 %,
  • forced expiratory volume in one second (FEV1) \< 800 ml or FEV 1 \< 30 %,
  • peripheral lung tumor was not visualised by RP-EBUS longer than 30 minutes
  • large vessels (more than 3 mm) near the tumor on the CT scan,
  • technically difficult to introduce cryoprobe and/or endobronchial blocker to current bronchi segment or subsegment,
  • excessive bleeding after transbronchial forceps biopsy, which was needed extra intervention to stop bleeding.
