Long-term effects of bone marrow transplantation

Area of Science:

• Pediatric Hematology/Oncology
• Transplantation Medicine
• Long-term Survivorship

Background:

• Increasing numbers of children are surviving longer after marrow transplantation.
• Delayed adverse effects are becoming more apparent in pediatric survivors.

Purpose of the Study:

• To identify and describe the spectrum of late effects following pediatric marrow transplantation.
• To emphasize the need for awareness to improve long-term outcomes.

Main Methods:

• Review of known late effects in pediatric marrow transplant survivors.
• Categorization of effects based on origin: transplant procedure, original disease, or preparative regimen.

Main Results:

• Late effects include engraftment instability, chronic graft-versus-host disease, and delayed immune recovery.
• Recurrent disease is a major concern related to the original illness.
• Therapy-related effects encompass neuroendocrine, ocular, dental, CNS dysfunction, and secondary malignancies.

Conclusions:

• Delayed effects significantly impact pediatric marrow transplant survivors' quality of life.
• Understanding these late complications is essential for proactive management and prevention of growth/developmental abnormalities.
