Ewing's sarcoma: prognosis and survival in Mexican children from a single institution.
A retrospective analysis of 55 patients with Ewing's sarcoma from an institution in Mexico was done between 1980 and 1993. The ages ranged between 2 and 16 years (mean 9.78); 39 were male and 16 female. The most frequent primary sites were in the humerus in 13 of 55 patients (23.6%), followed by the pelvis in 10 out of 55 (18%). ⋯ Patients in regimen 3 had a DFS of 47% at 36 months of follow-up compared to 20 and 25% for patients in regimens 1 and 2, respectively (p = .01). In those with trunk presentation the DFS was of 25% and in those with presentation in the extremities DFS was 50% (p = .01). Patients with pulmonary metastasic disease at diagnosis have a DFS of 20% in comparison to those without (44%) (p = .00061).
