Body Composition in Pediatric Solid Tumors: State of the Science and Future Directions. Issue 54 (11th September 2019) - Joffe, Lenat
Abstract: Sarcopenia (severe skeletal muscle wasting) and sarcopenic obesity (skeletal muscle wasting in the setting of excess fat) have been increasingly recognized as important prognostic indicators in adult oncology. Unfavorable changes in lean and adipose tissue masses manifest early in therapy and are associated with altered chemotherapy metabolism as well as increased treatment-related morbidity and mortality. Existing literature addresses the role of body composition in children with hematologic malignancies; however, data is lacking among solid tumor patients. Advances in imaging techniques for quantification of tissue compartments potentiate further investigation in this highly understudied area of pediatric oncology. The following review presents an in-depth discussion of body composition analysis and its potential role in the care of pediatric solid tumor patients. Integration of body tissue measurement into standard practice has broad clinical implications and may improve quality of life and treatment outcomes in this at-risk population.
