    Abstract:
    OBJECTIVE: Objective of our study was to evaluate the nutritional status and growth of children and adolescents with common malignancies of the musculoskeletal system at diagnosis, and undergoing multimodality therapy. METHODS: A retrospective analysis of data from 2001 to 2009 was conducted. Hospital charts were used as a source of clinical data. Primary endpoint of the analyses was to identify variations in anthropometric parameters at diagnosis and during the first 2 years of follow-up in children and adolescents with osteosarcoma or Ewing sarcoma. Factors contributing to disorders of growth in this population were sought. RESULTS: A total of 139 children were registered, 62 with Ewing sarcoma and 77 with osteosarcoma. At diagnosis 72.7% of all patients were classified as adequately nourished (BMI 5th to <85th percentiles). During treatment all anthropometric parameters were markedly reduced (P < 0.001) in both groups with extreme changes in body weight from -30% to +44%. This was pronounced in children affected by osteosarcoma (P < 0.05). During follow-up, recovery of body weight was noted in both groups. Height Z-scores remained low (P < 0.001) in comparison to the general population. After the observation period 43.4% of the children with osteosarcoma and 25.5% of the patients with Ewing sarcoma demonstrated an altered body mass. CONCLUSIONS: Pediatric patients with Ewing sarcoma or osteosarcoma are at an increased risk for developing malnutrition, in the form of either over- or underweight during multimodality therapy. Early recognition of abnormal body mass is required to prevent and to treat long-term comorbidities caused by malnutrition.
