    Ewing sarcoma survivors often retain good leg function after radiation and chemotherapy. Primary amputation is not always necessary, even for younger patients or those with femoral fractures.

    Area of Science:

    • Orthopedics
    • Pediatric Oncology
    • Radiation Oncology

    Background:

    • Ewing sarcoma is a primary bone cancer predominantly affecting children and young adults.
    • Treatment typically involves radiation therapy and systemic chemotherapy.
    • Assessing long-term functional outcomes in the lower extremity is crucial for patient quality of life.

    Purpose of the Study:

    • To evaluate the functional status of the lower extremity in patients who survived Ewing sarcoma.
    • To determine if radiographic changes correlate with functional outcomes.
    • To identify prognostic factors influencing functional results and inform treatment decisions regarding amputation.

    Main Methods:

    • Retrospective study of 29 patients with lower extremity Ewing sarcoma surviving ≥2 years post-therapy.

  • Clinical examination of 22 living patients categorized into four functional groups.
  • Review of serial radiographs for 22 patients to assess radiation-induced bone changes.
  • Analysis of prognostic factors including age at diagnosis, femoral fracture, and tumor location.

    • Main Results:

    • 13/22 patients had minor functional limitations (Group I), 5/22 moderate (Group II), 3/22 severe (Group III), and 1/22 required amputation (Group IV).
    • Radiographic bone changes did not correlate with functional outcomes.
    • Femoral fracture and age <16 years at diagnosis were associated with less favorable functional results.

    Conclusions:

    • Good functional outcomes are achievable for lower extremity Ewing sarcoma survivors treated with radiation and chemotherapy.
    • Primary amputation is often not justified based solely on tumor location or young patient age.
    • Further research into optimizing limb salvage strategies is warranted.
