ObjectivesTo analyze the demographics, survival, and treatment efficacy of pediatric sarcomas of the facial skeleton and skull.MethodsRetrospective study of cases from the US National Cancer Institute's Surveillance, Epidemiology, and End Results database. Pediatric patients between the ages of 0 and 18 diagnosed with a malignant sarcoma of either the mandible or the bones of skull, face, and associated joints from 1973 to 2013 were studied.ResultsIn total, 204 patients were included in the analysis. The average age at diagnosis was 11.39 (±5.15) years with a male-to-female ratio of 1.4:1. Whites were the most commonly affected race (76.0%). Malignant mandible sarcomas accounted for 29.9% of the cohort (n = 61). The most common pathology was osteosarcoma, which accounted for 43.6% of the cohort (n = 89). Among patients with known histologic grade (n = 95), 26.0% were AJCC stage III or IV. Overall, 5-year disease-specific survival (DSS) was 80.6%. When stratified by treatment modality, 5-year DSS was 86.0% for surgery alone, 67.9% for radiation alone, and 75.3% for surgery with adjuvant radiotherapy (p = 0.041).ConclusionsOsteosarcoma, Ewing's sarcoma, and chondrosarcoma are the most common subtypes of pediatric head and neck bone sarcoma. Such sarcomas more commonly affect whites and males during pubertal ages. Disease-specific survival is not affected by primary site. Surgery alone is the mainstay of treatment, and demonstrates higher 5-year disease-specific survival compared to radiotherapy alone. Adjuvant radiotherapy does not seem to increase survival, but further investigation is warranted.
