title: Prognosis of Ewing's sarcoma of the head and neck.
abstract: Five children with Ewing's sarcoma, an uncommon neoplasm originating in the facial bones, were treated with chemotherapy, surgery, and radiotherapy. Younger children have poor prognoses. Children with tumors originating in the mandible appear to have better prognoses. Hematogenic metastases were the most frequent and those originating from maxillary tumors showed much faster growth and were resistant to the chemotherapy used.
