EXERCISE in pediatric autologous stem cell transplant patients: a randomized controlled trial protocol

Area of Science:

• Pediatric oncology
• Immunology
• Exercise science

Background:

• Hematopoietic stem cell transplantation (HSCT) is crucial for treating childhood cancers but carries risks.
• Immune system recovery is vital for HSCT success, yet poorly understood in pediatric patients.
• Exercise is known to regulate the immune system in healthy individuals, but its role post-HSCT in children is unclear.

Purpose of the Study:

• To evaluate the effect of a structured exercise program on immune cell recovery in children undergoing autologous HSCT.
• To assess exercise's impact on quality of life, physical fitness, and sedentary behavior post-transplant.

Main Methods:

• A randomized controlled trial involving 24 pediatric patients (5-18 years) undergoing autologous HSCT.
• The intervention group received a phased exercise program (inpatient and outpatient) including strength, flexibility, and aerobic activities.
• Outcomes included immune cell recovery, cytokine levels, NK cell function, body composition, quality of life, and physical activity levels.

Main Results:

• Exercise intervention is hypothesized to enhance immunological recovery.
• Improvements in quality of life are expected with the exercise program.
• Reduced sedentary behavior and deconditioning are anticipated outcomes.

Conclusions:

• The study anticipates positive effects of exercise on immune recovery and patient well-being.
• Findings will inform larger, multi-site studies on exercise interventions in pediatric HSCT.
• This research provides crucial preliminary data for optimizing post-transplant care.
