A Ewing-sarcomás betegek tünetmentes túlélési esélyeinek értékelése a Gyermekonkológiai Szekció eredményei alapján

Abstract

Correlation between different prognostic factors and the overall survival of Ewing's sarcoma patients has been investigted. In this study data have been selected from the databank of Hungarian Pediatric Oncologist Section (1988-1999) (n=65). Whenever it was possible statistical analysis has been performed. Results: In our patients time interval from the primary symptoms to the diagnosis was 2-16 months. The average event-free survival in patients suffering from Ewing's sarcoma without metastasis is 0.39. Meanwhile, this value in patients with pulmonary or other metatasis is 0.24 (Kaplan-Meier analysis). Conclusion: Our results show a moderate difference between the Hungarian and the international event-free survival. Late detection is one of the answers of this discrepancy.
