Objective: Aim of this work is to assess clinical features, outcome and prognosis of adult patients diagnosed with Ewing Sarcoma (ES). Patients, Methods and Results: The records of 53 adult patients treated with Euro-Ewing protocol at Kuwait cancer control center (KCCC) over a period of 5 years were reviewed. Mean age was 26.9 ± 1.25 years. Thirty percent of patients presented with metastatic disease, and 65% of tumors were centrally located and 50% were ≥ 8 cm. All patients received initially VIDE protocol. 13.5% achieved complete remission (CR), and 57.7% achieved partial response (PR). Approximately 1/3 of patients underwent surgery which was adequate in 76% of them, and all patients received local radiotherapy. Post local treatment 56% of patients received VAC and 44% received VAI protocol. Mean treatment duration was 11 months ± 0.54. Median follow-up duration was 38.39 (33.49 - 43.28) months At the end of follow up 20% of patients relapsed locally and 36% distally. Median PFS was 46.9 months (95% CI 41.42 - 52.39), Median OS was 55.43 ms (95% CI 30.71 - 75.74);survivals at 3 and 5 years were 88%, 46% respectively. Conclusion: In this series metastases at presentation and wide surgical margins were the most important prognostic factors. Multimodality therapy is necessary for this rare disease.
