Ewing's sarcoma: experience with 12 cases.
Twelve patients with localized Ewing's sarcoma were treated between 1980-1990 at the Istanbul School of Medicine, Department of Pediatric Oncology-Hematology, Oncology Research and Treatment Center and Our Children Leukemia Foundation. There were 8 boys and 4 girls, with a mean age of 8.1 (range 3-17) years. The tumors were in the femur in 3 patients, in the humerus and rib in 2 patients each and in the tibia, radius, vertebra, clavicula and pelvis in 1 patient each. Chemotherapy alone was applied in 2 patients, 1 patient had chemotherapy and radiotherapy. The remaining 9 cases were treated with Chemotherapy and radiotherapy (during the chemotherapy). The chemotherapy protocols were: VAC (n = 5), VACA (n = 3), IVAD (n = 3) and T.9 (n = 1). One patient died from the disease itself. Remissions were achieved in the other 11 patients. After 5 to 95 months (mean: 22 months) 7 patients had relapsed (4 had local and 3 had distant metastases). Three patients were not able to be followed, 3 died due to additional problems (infection, cardiotoxicity). The best prognosis was achieved when Ewing's sarcoma initiated in the long bones, with less than 100 ml tumor volumes and patients were under 5 years old. There were no significant differences among chemotherapy protocols.
