title: Radiotherapy for rhabdomyosarcoma: indications and outcome.
abstract: Rhabdomyosarcoma is the most common soft tissue sarcoma of childhood. Improvements in the clinical outcomes of rhabdomyosarcoma have been secondary to the intensification and refinement of treatment investigated by the Intergroup Rhabdomyosarcoma Study Group. Advances in diagnostic imaging techniques have led to improvements in staging and contribute to precision in radiation field design. Radiation treatment has been integrated into the primary treatment of most patients with rhabdomyosarcoma. Each treatment site has special considerations with regards to prognosis, outcomes and potential morbidities that affect the choice of local therapy. Advanced radiotherapy techniques using conformal treatment with intensity-modulated radiotherapy and proton therapy are particularly advantageous for the treatment of sites close to critical structures, such as the head and neck and genitourinary system. Active investigation is underway to develop strategies to reduce the radiation dose and volume in an effort to minimise late toxicity and improve the therapeutic ratio.
