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
