Ewing sarcoma (also known as Ewing’s sarcoma) is a tumor that arises primarily in the bone and soft tissue. It can either affect the long bones such as the femur (thigh), tibia (shin) or humerus (upper arm), or the flat bones like the ribs, pelvis or spine. It also can involve the soft tissues around the tumor site.

While rare, Ewing sarcoma is the second most common malignant bone tumor in children and adolescents after osteosarcoma. It is slightly more common in males than females; and usually occurs in children and young adults between the ages of 10 and 20. Ewing sarcoma is highly malignant and can metastasize (spread) rapidly to other areas of the body including the bone marrow, lungs, kidneys, heart, adrenal gland and other soft tissues. Accurate diagnosis and staging, and prompt, carefully orchestrated therapy are particularly critical when treating Ewing sarcoma.

The University of Chicago Medicine Comer Children’s Hospital has a multidisciplinary team of experts with the experience and advanced resources to diagnose, analyze and treat Ewing and other bone sarcomas. Pediatric oncologists, radiation oncologists, orthopaedic surgeons, pathologists, nurse specialists and others at Comer Children’s work together to strive for the best results for children with bone sarcomas.
