    Bone marrow transplantation (BMT) can lead to restrictive lung changes in children, particularly those receiving intensive chemotherapy and radiation. Less intensive regimens for aplastic anemia and leukemia in remission appear safer for pulmonary function.

    Area of Science:

    • Pediatric Hematology Oncology
    • Pulmonary Medicine
    • Transplantation Science

    Background:

    • Bone marrow transplantation (BMT) is a critical treatment for pediatric leukemia and aplastic anemia.
    • Pulmonary complications following BMT can significantly impact patient outcomes.
    • The long-term effects of different BMT conditioning regimens on lung function require further investigation.

    Purpose of the Study:

    • To prospectively evaluate pulmonary function in children undergoing bone marrow transplantation.
    • To identify risk factors associated with pulmonary toxicity after BMT.
    • To assess the impact of conditioning regimens on lung health in pediatric BMT recipients.

    Main Methods:

    • Prospective study of 25 children with leukemia or aplastic anemia undergoing BMT.

  • Pulmonary function tests (PFTs) administered to assess lung capacity and function.
  • Correlation of PFT results with conditioning regimen intensity and underlying disease.

    • Main Results:

    • Four out of 17 patients (56%) who received intensive conditioning for relapsed leukemia developed restrictive lung changes.
    • Patients transplanted for aplastic anemia or non-relapsed leukemia with less intensive regimens maintained normal pulmonary function.
    • Interstitial pneumonia was an infrequent cause of mortality.

    Conclusions:

    • Intensive conditioning regimens, including high-dose cyclophosphamide, total body irradiation, and BCNU, are associated with restrictive lung changes post-BMT.
    • Less intensive regimens for aplastic anemia and leukemia in remission appear to preserve pulmonary function.
    • Pulmonary function testing is crucial for monitoring and characterizing the pulmonary toxicity of novel BMT regimens.
