Osteoporosis after stem cell transplantation.

Area of Science:

• Hematology
• Oncology
• Bone Metabolism

Background:

• Long-term survival after hematopoietic cell transplantation (HCT) is increasing.
• Late complications, including osteoporosis (OP), are increasingly recognized in HCT survivors.
• Osteoporosis affects up to 50% of allogeneic HCT recipients.

Purpose of the Study:

• To review the pathological mechanisms of OP post-HCT.
• To discuss diagnostic approaches for OP in HCT recipients.
• To summarize current treatment recommendations and identify research gaps.

Main Methods:

• Literature review of studies on osteoporosis following HCT.
• Analysis of pathological mechanisms contributing to bone loss.
• Synthesis of diagnostic criteria and treatment guidelines.

Main Results:

• Osteoporosis is a significant and frequent complication of HCT.
• Established pathological pathways contribute to decreased bone mineral density.
• Evidence supports various treatment strategies, though uncertainties remain.

Conclusions:

• Osteoporosis is a critical late complication of HCT requiring vigilant management.
• Further research is needed to address uncertainties in diagnosis and treatment.
• Optimizing bone health is essential for improving long-term outcomes in HCT survivors.
