Pediatric sarcomas and related tumors of the head and neck.

Sarcomas of the head and neck region are a rare group of tumors in children and present challenges with regard to evaluation and treatment. Rhabdomyosarcomas are the most common sarcomas of the head and neck in children. Presence of metastases and complete surgical resectability continue to be the most relevant clinical prognostic factors in patients with sarcomas. However, many patients present with unresectable tumors; these require radiation therapy, which is associated with concerns about immediate and long-term side effects. New technologies, including proton beam therapy (PBT), appear very promising in terms of reducing acute and long-term toxic effects. A multi-disciplinary approach is required for best long-term outcomes in children with head and neck sarcomas.
