Abstract
Lung-only metastasis in Ewing Sarcoma (ES) is a rare presentation in an otherwise common skeletal malignancy with a poor 5-year overall survival (OS) of 30% and a 10-year event-free survival (EFS) of 50.3%, respectively. We report a first case of a 11-year-old male with ES lung-only metastatic disease who underwent whole lung irradiation (WLI) post standard chemotherapy with Volumetric Modulated Arc Therapy (VMAT) with an intent to reduce the radiation dose to critcial organs at risk (OAR’s) viz heart and spinal cord and document dosimetric paramters.
