AI-Summary

What this Trial Is About

This study investigates a type of cell, called abnormal clonogenic epithelial cells, in patients with bronchiolitis obliterans syndrome who have had an donor stem cell transplant or a lung transplant. Learning more about clonogenic cells in these patients may help doctors to detect signs of bronchiolitis obliterans syndrome earlier in future patients.

Eligibility Criteria

Eligible

You may qualify if you...

  • Allo-HCT recipients undergoing bronchoscopy at MD Anderson Cancer Center who consent to study airway brushings
  • Patients with advanced BOS (FEV1 ≤ 75% predicted) meeting NIH criteria
  • Patients with early BOS (≥ 10% decline in FEV1 but ≥ 75% predicted) with additional high-risk features
  • Patients with no pulmonary impairment (FEV1 within 5% of baseline)
  • Lung transplant recipients undergoing bronchoscopy at Houston Methodist who consent to study airway brushings
  • Patients with BOS Stage 2 or higher (≥ 35% decline in FEV1 from baseline)
  • Patients with BOS Stage 0p or 1 (10-35% decline in FEV1 from baseline)
  • Patients undergoing screening bronchoscopy without FEV1 decline
  • Patients with undiagnosed lung cancer or chronic obstructive pulmonary disease diagnosed by pulmonary function testing
Not Eligible

You will not qualify if you...

  • Bronchoscopy performed on an emergency basis for life-threatening issues
  • Patients unwilling to give consent for study airway brushings
