Insights
Fatigue significantly impacts children with advanced cancer, often linked to other symptoms and treatment side effects. Effective fatigue management remains a challenge, requiring more research and targeted interventions.
Area of Science:
- Pediatric Oncology
- Palliative Care
- Symptom Management
Background:
- Fatigue is a common and poorly understood symptom in children with advanced cancer.
- Understanding fatigue is crucial for improving quality of life in this population.
Purpose of the Study:
- To describe the experience of fatigue in children with advanced cancer.
- To identify factors associated with fatigue and its treatment.
Main Methods:
- Retrospective cross-sectional study involving 141 parents of children who died of cancer.
- Data collected from two U.S. pediatric hospitals.
Main Results:
- 96% of children experienced fatigue in their last month of life, with nearly 50% suffering significantly.
- Fatigue was associated with pain, dyspnea, anorexia, nausea/vomiting, fear, and treatment side effects.
- Factors independently associated with fatigue suffering included nausea/vomiting, anorexia, and fear. Less experienced oncologists were associated with children suffering from fatigue. Fatigue-directed treatment was rarely successful.
Conclusions:
- Fatigue is a prevalent and distressing symptom for children with advanced cancer at the end of life.
- Current palliative strategies for fatigue are often unsuccessful.
- There is a need for greater focus on factors contributing to fatigue and the development of effective interventions.
Context:
Fatigue is a prevalent source of suffering in children with advanced cancer; yet, little is known about it.
Objectives:
This study aimed to describe fatigue experienced by children with advanced cancer and to identify the factors associated with suffering from fatigue and its treatment.
Methods:
A retrospective cross-sectional study of 141 parents of children who died of cancer (response rate: 64%) was conducted in two tertiary-level U.S. pediatric hospitals.
Results:
By parent report, 96% of children experienced fatigue in the last month of life. Nearly 50% experienced significant suffering from fatigue; this was associated with suffering from pain, dyspnea, anorexia, nausea/vomiting, diarrhea, anxiety, sadness, or fear (P<0.05), and with side effects from pain or dyspnea treatment (P<0.05). In multivariate analysis of symptom-related factors, suffering from nausea/vomiting (odds ratio [OR]=3.93, 95% confidence interval [CI]=1.23-12.61, P=0.02); anorexia (OR=7.52, 95% CI=1.87-30.25, P=0.005); and fear (OR=5.13, 95% CI=2.03-12.96, P ≤ 0.001) remained independently associated with fatigue. Children suffering from fatigue had primary oncologists with fewer years' experience than children who did not suffer from fatigue (mean=7.7 years, standard deviation [SD]=4.9 vs. mean of 9.9 years, SD=6.0, P=0.02). Among children with fatigue, 17 of 129 (13%) received fatigue-directed treatment, which was successful in 3 of 12 (25%). Children experiencing side effects from dyspnea or pain treatment were more likely to be treated for fatigue (relative risk=1.25, 95% CI=1.06-1.47, P=0.009).
Conclusion:
Fatigue is a common source of suffering in children with cancer at the end of life. Palliation of this symptom is rarely successful. Increased attention to factors associated with fatigue and effective interventions to ameliorate fatigue are needed.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
