Insights
Pediatric cancer patients receiving chemotherapy showed altered omega-3 and omega-6 fatty acid metabolism, despite normal nutritional status. Further research is needed to guide targeted supplementation for these children.
Area of Science:
- Biochemistry
- Pediatric Oncology
- Nutritional Science
Context:
- Limited research exists on the metabolic and nutritional status of pediatric cancer patients.
- Chemotherapy can significantly impact a child's overall health and metabolic processes.
Purpose:
- To investigate nutritional and metabolic alterations in children with cancer.
- To specifically analyze plasma fatty acid profiles post-chemotherapy compared to healthy controls.
Summary:
- Twelve children (0-16 years) with cancer, who had received chemotherapy, were assessed for nutritional status, anthropometry, and plasma fatty acids.
- Results indicated no changes in anthropometric or general biochemical parameters, but revealed alterations in omega-3 and omega-6 polyunsaturated fatty acids.
Impact:
- Suggests a potential partial deficiency in polyunsaturated fatty acid metabolism in pediatric cancer patients post-chemotherapy.
- Highlights the need for further research to develop specific nutritional supplementation strategies for improved patient outcomes.
Unlabelled:
The small number of cases of cancer in children and the difficulties of research, have contributed to there being few studies on the metabolic and nutritional status of these patients. The main objective of this study was to investigate the nutritional and metabolic alterations in children with cancer, and specifically the plasma fatty acid profile after receiving chemotherapy, compared with a group of healthy children.
Methods:
We selected 12 children with cancer aged between 0 and 16, who had received at least one cycle of chemotherapy, one month before the study and were not end-stage disease. Nutritional survey was conducted, anthropometric measurements, general biochemical analysis and profile of fatty acids in plasma were evaluated.
Results:
No changes in anthropometric and nutritional biochemical parameters were detected. In the omega-6 fatty acids, lower values of linoleic and docosapentaenoic acid, and higher levels of gamma-linolenic acid, and normal levels of arachidonic acid were observed. In the omega-3, we found normal values of alpha-linolenic acid and docohexanoic acid, and lower values of eicosapentaenoic acid.
Conclusion:
It seems glimpsed a partial deficiency in the metabolism of polyunsaturated fatty acids in children with cancer, good nutrition and having received at least one cycle of chemotherapy. Further research is needed to allow specific supplementations.
