Surgery is generally the preferred approach if the lesion is resectable.
If a very young child has an ETB, surgery may be a less morbid therapy than radiation therapy because of the retardation of bone growth caused by radiation. Another potential benefit for surgical resection of the primary tumor is information concerning the amount of necrosis in the resected tumor. Patients with residual viable tumor in the resected specimen have a worse outcome compared to those with complete necrosis. Radiation therapy should be employed for patients who do not have a surgical option that preserves function and should be used for patients whose tumors have been excised but with inadequate margins. Radiation therapy should be delivered in a setting in which stringent planning techniques are applied by those experienced in the treatment of Ewing's family of tumors.
