Most embryonal rhabdomyosarcomas are very sensitive to radiotherapy, and those who have completed surgery to remove the tumor can be treated with radiotherapy within 1 week after surgery. Children with skull base invasion who have obvious compression symptoms and need urgent radiotherapy can be treated with radiotherapy before chemotherapy. If the tumor is too large for surgery, radiotherapy is recommended. If the primary tumor is located in an important organ that cannot be removed surgically, particle radiotherapy can be considered. Embryonal rhabdomyosarcoma requires a combination of treatments, such as surgery, radiotherapy and chemotherapy. Radiation therapy is a very important part of the treatment, including external radiation therapy and particle implantation. Current guidelines recommend no radiotherapy for embryonal rhabdomyosarcoma stage I, while radiotherapy is required for embryonal rhabdomyosarcoma stages II-IV. Adenoid rhabdomyosarcoma has local recurrence, so radiotherapy is required for stages I-IV.
