Summary
Bone marrow transplantation is crucial for hematogenous cancers but involves intense treatment leading to numerous complications. Radiologists must recognize these complications, categorized by timing post-transplant, to ensure timely patient care.
Area of Science:
- Hematology
- Oncology
- Radiology
Background:
- Bone marrow transplantation (BMT) has advanced cancer treatment, necessitating intense pre-transplant conditioning.
- Conditioning regimens (chemotherapy, irradiation) cause profound immunosuppression, increasing patient vulnerability.
- Post-BMT complications are common and categorized by time intervals: pre-engraftment, post-engraftment, and delayed.
Purpose of the Study:
- To outline the spectrum of complications following bone marrow transplantation.
- To emphasize the importance of radiologists' familiarity with BMT clinical aspects and potential complications.
- To facilitate early detection and management of life-threatening post-transplant events.
Main Methods:
- Review of clinical aspects and complications associated with bone marrow transplantation.
- Classification of complications based on temporal intervals relative to engraftment.
- Identification of specific infectious and non-infectious complications within each interval.
Main Results:
- Pre-engraftment complications include infections, toxic effects (e.g., pneumonitis), hepatic veno-occlusive disease, and graft rejection.
- Post-engraftment complications encompass infections, acute graft-versus-host disease (GVHD), and pneumatosis intestinalis.
- Delayed complications involve chronic GVHD and cancer recurrence.
Conclusions:
- Bone marrow transplantation is associated with a wide range of complications requiring vigilant monitoring.
- Radiologists play a critical role in identifying early signs of potentially life-threatening complications post-BMT.
- Understanding the timing and nature of these complications is essential for effective patient management and improved outcomes.
