Inferior outcomes for overweight children undergoing allogeneic stem cell transplantation

Area of Science:

• Pediatric Hematology Oncology
• Transplantation Immunology
• Obesity Medicine

Background:

• Allogeneic stem cell transplantation (SCT) is a critical treatment for various pediatric diseases.
• The impact of overweight status on outcomes in pediatric SCT recipients is not well-defined.
• Obesity is a growing concern in pediatric populations, necessitating investigation into its effects on complex medical procedures.

Purpose of the Study:

• To determine if overweight children undergoing allogeneic SCT have inferior overall survival compared to non-overweight children.
• To analyze the association between overweight status and survival post-allogeneic SCT in pediatric patients.
• To identify potential risk factors influencing survival in pediatric SCT.

Main Methods:

• Retrospective cohort study design.
• Inclusion criteria: Children aged 2 years or older who received allogeneic SCT.
• Overweight defined as body mass index (BMI) at or above the 95th percentile.

Main Results:

• 17% (54/325) of the study cohort were classified as overweight.
• Five-year overall survival was significantly lower in the overweight group (46.6% +/- 7.3%) compared to the non-overweight group (59.5% +/- 3.2%).
• A statistically significant difference in survival was observed (P = 0.02).

Conclusions:

• Overweight children undergoing allogeneic SCT demonstrate inferior overall survival.
• Weight status is a significant factor impacting survival outcomes in pediatric allogeneic SCT.
• Further research into weight management strategies for pediatric SCT candidates is warranted.
