Ewing's family of tumors in adults: multivariate analysis of survival and long-term results of multimodality therapy in 182 patients.

Abstract

Based on our experience and a review of the literature, we concluded that the natural history and the prognosis of the Ewing's family of tumors in adults are not different from that found in children. A greater tumor bulk in adults may explain the less favorable prognosis previously reported by others. Outcome could be adequately monitored by a simple prognostic index.
