Özet
Objective: The aim of this study was to evaluate prognostic factors, survival rate and the efficacy of the treatment modalities used in patients with extraskeletal Ewing's sarcoma. Methods: Data of patients with extraskeletal Ewing's sarcoma followed up at our center between 1997 and 2010 were retrospectively analyzed. Results: The median age of 27 patients was 24 years (range, 16-54 years). The median follow-up was 31.8 months (range, 6-144 months). Tumor size was between 1.5 and 14 cm (median: 8 cm). Eighty-five percent of patients had localized disease at presentation and 15% had metastatic disease. Local therapy was surgery alone in 16% of patients, surgery combined with radiotherapy in 42% and radiotherapy alone in 27%. All patients were treated with vincristine, doxorubicin, cyclophosphamide and actinomycin-D, alternating with ifosfamide and etoposide every 3 weeks. In patients with localized disease at presentation, the 5-year event-free survival and overall survival were 59.7 and 64.5%, respectively. At univariate analysis, patients with tumor size ≥8 cm, high serum lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy and positive surgical margin had significantly worse event-free survival. The significant predictors of worse overall survival at univariate analysis were tumor size 8≥ cm, high lactate dehydrogenase, metastasis at presentation, poor histological response to chemotherapy, radiotherapy only as local treatment and positive surgical margin. Conclusions: Prognostic factors were similar to primary osseous Ewing's sarcomas. Adequate surgical resection, aggressive chemotherapy (vincristine, doxorubicin, cyclophosphamide and actinomycin-D alternating with ifosfamide and etoposide) and radiotherapy if indicated are the recommended therapy for patients with extraskeletal Ewing's sarcoma. © The Author 2012.
