In Ewing’s sarcoma, the goal is removal in healthy tissue with a margin of safety (tumor-free resection margins).
The following form of surgical therapy is available:
- Wide resection – method of choice for malignant (malignant) bone tumors.
- Procedure: wide and radical resection (surgical removal) of the tumor with a safety margin of 5 cm (proximal (toward the center of the body) and distal (away from the center of the body)).
- After tumor removal, osteosynthesis (insertion of a spongiosaplasty) or reconstruction of the resulting bone defect is performed, e.g., in the form of a tumor endoprosthesis, a bone graft, or muscle, nerve, and vascular replacement plastics. For children, growing endoprostheses (joint replacement) are suitable.
- Through the use of mega endoprostheses amputations of the affected limb are now rarely necessary (“Ultima ratio” (last resort)).
Metastases are also resected.
