Ewing's sarcoma is the second most common primary bone malignancy in childhood and adolescence. We present a standardized interdisciplinary treatment protocol according to the EURO-E.W.I.N.G. 99 study, applied in the treatment of a 7-year-old patient with localized Ewing's sarcoma of the left mandible. After six blocks of VIDE (vincristine/ifosfamide/doxorubicin/etoposide) chemotherapy and stem cells rescue, intensity modulated external radiation with 48.6 Gy and subsequent high dose therapy with busulphan-melphalan were administered. Tumor resection and immediate bony reconstruction was performed using a microvascular fibula graft 10 weeks after radiation. Because of the effective neoadjuvant treatment, no extensive soft tissue resection was necessary. Healing of the osteosynthesis was uneventful. No local or systemic recurrence and no signs of significant facial deformity were found after 12 month follow-up. The presented case underlines the requirement for multidisciplinary protocols involving radiologists, pathologists, oncologists, radiation oncologists, and surgeons for accurate diagnosis and appropriate therapy. To preserve cosmetics and function within the craniofacial area after tumor resection in children, microvascular reconstructive procedures can be successfully performed with a vascularized fibular graft. |
