title: Incidence and survival of pediatric soft tissue sarcomas in moscow region, Russian Federation, 2000-2009.
abstract: The aim of the study was to assess the incidence and survival rates of soft tissue sarcomas (STSs) in children 0-14 years of age in Moscow Region, Russian Federation. The database of childhood population-based cancer registry of Moscow Region was used as a data source. Tumors were stratified according to International Classification of Childhood Cancer, 3d ed. Sixty-eight cases of STS were registered from 2000 to 2009. Crude incidence rate was 0,78, and age-standardized incidence rate using World Standard Population was 0,81 per 100.000 children/year. The highest age-specific incidence was observed in infants: 1,76 per 100.000 children/year. Rhabdomyosarcoma (RMS) was the most common histological type comprising 54,4% of all STS. 5-year observed survival (OS) of all patients with STS was 64,1 (95% CI 55,0-73,2). There was no statistically significant difference in OS between RMS-59,2 (95% CI 47,0-71,4) and nonrhabdomyosarcoma STS-69,3 (95% CI 55,8-82,8) (P = 0.63). Incidence and survival rates of STS observed in the study were comparable to the other Eastern European countries.
