Late effects of allogeneic bone marrow transplantation in children

Area of Science:

• Hematology
• Oncology
• Transplantation Medicine

Background:

• Bone marrow transplantation (BMT) is a life-saving procedure for various hematologic and oncologic conditions.
• While BMT offers significant benefits, long-term survivors are susceptible to a range of adverse health issues known as late sequelae.
• Identifying and managing these late effects is critical for improving the quality of life for BMT survivors.

Purpose of the Study:

• To comprehensively review the spectrum of late sequelae following bone marrow transplantation.
• To emphasize the necessity of lifelong surveillance for early detection and intervention of post-BMT complications.

Main Methods:

• This review synthesizes existing literature on the late effects of bone marrow transplantation.
• Key complications and their management strategies are discussed based on current evidence.

Main Results:

• Late sequelae encompass diverse complications including growth impairment, gonadal failure, and organ-specific toxicities (neurological, pulmonary, renal, hepatic).
• Increased risk of secondary malignancies and chronic graft-vs.-host disease are significant long-term concerns.
• Psychosocial challenges also represent a substantial burden for survivors.

Conclusions:

• Bone marrow transplantation can lead to a wide array of late sequelae affecting multiple organ systems and overall well-being.
• Lifelong follow-up care is essential for BMT survivors to proactively identify and manage these potential long-term complications.
• Effective management strategies and ongoing research are vital to mitigate the impact of late sequelae and enhance long-term outcomes for transplant recipients.
