Prognostic features of pediatric soft-tissue sarcomas.
Eight hundred ninety-two patients under 20 years of age with soft-tissue sarcomas histologically diagnosed between 1955 and 1971 (before the era of combined modality therapy) were reviewed to delineate important prognostic variables. Differing histologic findings, extent of disease at initial presentation, and site of the primary tumor correlated with prognosis; age, sex, and race did not affect survival significantly. Patients with fibrosarcomas, liposarcomas, and leiomyosarcomas had improved survival rates when compared with adults with the same histologic findings; patients with localized tumors and extremity primary sites had the best prognosis. Patients with rhabdomyosarcomas, disseminated disease, or retroperitoneal primary sites had the worst prognosis. These data suggest that some childhood sarcomas are not as aggressive as adult sarcomas or childhood rhabdomyosarcomas. Therefore they may not require the adjuvant therapy shown to be beneficial in childhood rhabdomyosarcomas.
