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.
五名患有尤因肉瘤的儿童接受了化疗、手术和放疗，尤因肉瘤是一种起源于面骨的罕见肿瘤。年龄较小的儿童预后较差。起源于下颌骨的肿瘤患儿似乎预后较好。血行转移最为常见，而上颌肿瘤引起的血行转移生长速度更快，且对所用化疗具有耐药性。
