Present trends in treatment of Ewing's sarcoma.

The prognosis of Ewing's sarcoma, the first malignant tumor in children under 10, has improved dramatically in the last 10 yrs. The authors review the signs and symptoms that permit diagnosis and analyse the improvement in treatment, based on multidrug's combination, neoadjuvant chemotherapy and surgical treatment of the primary. They point out the necessity of closed multidisciplinary co-operation to treat these patients. Under these conditions, disease free survival now reaches more than 90% at 3 years 1/2.
