Evaluation of fatigue and related factors in survivors of pediatric cancer and hematopoietic stem cell transplant.

This study sought to better understand specific factors contributing to fatigue in survivors of pediatric cancer and hematopoietic stem cell transplant (HSCT). As part of a larger study evaluating long-term psychosocial functioning of pediatric cancer survivors, N = 87 participants completed measures assessing fatigue and emotional and behavioral functioning. Chart abstraction was used to catalog diagnosis, treatments received, treatment intensity, and late effects. Results suggest clinically significant fatigue in n = 4 (4.6%) of survivors participating in this study. Fatigue was greater for participants with more recent diagnoses and who were more recently off treatment and was positively associated with parent and self-report of internalizing (emotional) and externalizing (behavioral) symptoms. Participants with more severe late effects suffered greater fatigue; however, fatigue was not associated with treatment intensity or therapy type. Fatigue is an important variable to consider in evaluating the social, emotional, behavioral, and physical well-being of cancer and HSCT survivors. Interventions are needed to address fatigue directly, while also addressing both contributing factors to fatigue and potential negative outcomes that result from fatigue in survivorship.
