Abstract:
: Ewing sarcoma is a rare malignant tumor that mainly affects children and young adults. Its management relies on a multidisciplinary approach combining chemotherapy, surgery, and radiotherapy. This retrospective study describes the clinical characteristics, treatment, and outcomes of six patients surgically treated for Ewing sarcoma at the Department of Orthopaedic Trauma Surgery, Hassan II University Hospital, Fez, Morocco. The mean age was 31 years, with a male predominance (5 males, 1 female). Four tumors were osseous and two were extraosseous, predominantly involving the lower limbs (83%). Histological confirmation was obtained in all patients. Neoadjuvant chemotherapy was administered in five cases, followed by limb-sparing surgery in three patients and amputation in two. Adjuvant radiotherapy was performed in two patients. After a mean follow-up of 18 months, three patients achieved complete remission, two developed recurrence or metastatic disease, and one was lost to follow-up. Surgery remains the cornerstone of local treatment and, when integrated into a multidisciplinary strategy, improves local control while maximizing limb preservation whenever oncologically feasible.
