Study Summary

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.

Primary Outcome

The relationship between the proportion of abnormal cells and degree of air trapping and lung abnormalities will be described through simple correlation. Exploration of non-linear relationships or rank-based summaries will be considered as appropriate.
