This is a research study involving patients who have a type of cancer called Ewing sarcoma that has spread (metastasized) to the lung or pleura (the membrane covering the lungs). Ewing sarcoma is a cancerous tumor that forms in the bone or soft connective tissues. These tumors spread quickly to other areas of the body including the lungs. Ewing sarcoma is always fatal without treatment.
The overall goal of the study is to improve the outcome of individuals with Ewing sarcoma.
