Younger age and surgical intervention improve survival for extraskeletal Ewing's sarcoma patients. Surgical resection is recommended for all cases, as it significantly impacts outcomes in this rare cancer.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Pediatric Oncology

Background:

  • Extraskeletal Ewing's sarcoma is a rare primary malignancy affecting young individuals.
  • Limited data exist on optimal surgical and oncologic treatment strategies for this condition.

Purpose of the Study:

  • To evaluate prognostic factors and outcomes in patients with extraskeletal Ewing's sarcoma treated with multimodality therapies.
  • To determine the impact of age, tumor characteristics, and surgical intervention on patient survival.

Main Methods:

  • Retrospective review of 24 patients with extraskeletal Ewing's sarcoma.
  • Data collected included tumor location, size, patient age, disease stage, surgical margins, radiation dose, and chemotherapy details.
  • Follow-up averaged 64 months for surviving patients.

Main Results:

  • Overall 5-year survival was 61% and disease-free survival was 54%.
  • Younger age at diagnosis and surgical resection (wide or less-than-wide) were associated with improved survival.
  • Wide resection showed a survival advantage over less-than-wide resection; tumor size and metastatic disease were not significant prognostic factors.

Conclusions:

  • Age and surgical treatment are critical prognostic variables for extraskeletal Ewing's sarcoma.
  • Surgical resection should be considered for all patients diagnosed with extraskeletal Ewing's sarcoma.
  • Tumor size, location, disease stage, and radiation therapy did not significantly impact survival in this cohort.
