Clinical outcomes of rhabdomyosarcoma and Ewing's sarcoma of the head and neck in children.

OBJECTIVE: To review our experience and critically evaluate treatment strategy and results in children with head and neck rhabdomyosarcoma and Ewing's sarcoma. METHODS: Retrospective charts review of children affected by non-orbital rhabdomyosarcoma or Ewing's sarcoma of the head and neck who were treated at our institution from January 1996 to August 2009. RESULTS: Seven consecutive children with head and neck rhabdomyosarcoma or Ewing's sarcoma were identified. Four children had rhabdomyosarcoma, 3 children had Ewing's sarcoma. Regions involved were: cheek, ethmoid and maxillary sinuses, nasopharynx, middle ear/mastoid and frontal bone. In one case, surgery was performed as primary treatment modality; the other children were treated firstly with chemotherapy. Three patients underwent surgical resection after chemotherapy, while 4 patients received radiotherapy. Five children are disease free after a median of 7.7 years from initial diagnosis. Two patients relapsed after 10 and 29 months from initial diagnosis respectively; despite the administration of additional therapy both children died of disease. CONCLUSION: Treatment for rhabdomyosarcoma and Ewing's sarcoma consists in a multimodal therapy involving chemotherapy, radiotherapy and surgery. The optimum use, timing and intensity of these three treatments are still matters of international debate. Chemotherapy in association with radiotherapy has proven capable to obtain local and distant control of disease. But when surgery is unfeasible or fails in radicality, local control is difficult without radiotherapy. Despite additional therapeutic efforts, prognosis of relapsing disease remains poor
