Insights
Worrying and irritability are key symptoms in children with acute leukemia undergoing chemotherapy. Emotional symptoms, especially in older children and during induction/remission phases, require attention.
Area of Science:
- Pediatric Oncology
- Symptom Management
- Psychosocial Oncology
Background:
- Children with acute leukemia experience significant symptom burden during chemotherapy.
- Limited research exists on the interconnectedness of these symptoms in pediatric acute leukemia.
Purpose of the Study:
- To identify core symptoms experienced by children with acute leukemia during chemotherapy.
- To elucidate the interrelationships among these symptoms using network analysis.
Main Methods:
- A network analysis was conducted on data from 469 children with acute leukemia.
- The Memorial Symptom Assessment Scale 10-18 (MSAS 10-18) was used to assess symptom prevalence and severity.
- Centrality indices and network density were employed to analyze symptom interrelationships.
Main Results:
- Worrying and irritability were identified as central symptoms based on strength, closeness, and betweenness.
- Lack of energy was the most prevalent but less central symptom.
- Symptom network density differed significantly during induction and remission phases compared to other cycles.
Conclusions:
- Network analysis is a valuable tool for understanding symptom clusters in pediatric acute leukemia.
- Emotional symptoms, particularly during induction/remission and in older children, warrant focused assessment.
- Further longitudinal research is needed to explore dynamic symptom networks and causal relationships.
Purpose:
Children with acute leukemia have suffered from a considerable symptom burden during chemotherapy. However, few studies have focused on exploring the mechanisms among symptoms in children with acute leukemia. Our study aims to explore core symptoms and describe the interrelationships among symptoms in children with acute leukemia during chemotherapy.
Methods:
From January 2021 to March 2023, 469 children with acute leukemia were recruited from 20 Chinese cities. The Memorial Symptom Assessment Scale 10-18 (MSAS 10-18) was used to evaluate the prevalence and severity of symptoms during chemotherapy. A network analysis was performed by the R software based on 31 symptoms. Centrality indices and density were used to explore core symptoms and describe interrelationships among symptoms in the network during chemotherapy.
Results:
Worrying and feeling irritable were the central symptoms across the three centrality indices, including strength, closeness, and betweenness. Lack of energy was the most prevalent symptom; however, it was less central than other symptoms. The density of the "induction and remission" network significantly differed from other cycles' counterparts (p < 0.001). Global strength was greater in the " ≥ 8 years group " network than the " < 8 years group " network (p = 0.023).
Conclusion:
Network analysis provides a novel approach to identifying the core symptoms and understanding the interrelationships among symptoms. Our study indicates the need to assess emotional symptoms in children with acute leukemia during chemotherapy, especially during the induction and remission phases, as well as in older children. Future research is imperative to construct trajectories of dynamic symptom networks and centrality indices in longitudinal data to investigate the causal relationships among symptoms.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
