Individuals less than 20 years of age represented 5.6%, with rhabdomyosarcoma being the most common subtype. In adults, the most common types were Kaposi sarcoma, fibrohistiocytic tumors, and leiomyosarcoma. Rhabdomyosarcoma was the only entity with a median age &lt;20 years. Male predominance (male\/female of 1.5:1) was noticed for almost all types of STS, except for alveolar soft part sarcoma and leiomyosarcoma. Tumor stage was similar across different age groups. Younger patients (&lt;50 years) had significantly better survival than older patients (88.8\u2009\u00b1\u20090.2% vs. 40\u2009\u00b1\u20090.3%, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001), but for most histologies the survival decline with advancing age was gradual and did not occur abruptly at the onset of adulthood. The decline in survival with advancing age was particularly significant for rhabdomyosarcoma.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>With few exceptions, the clinical features of STS are similar in children and adults. However, individuals over 50 years of age have an inferior survival.
