title: Sarcomas across the age spectrum.
abstract: In most cancers, the age of the affected patient has a significant influence on how that cancer is approached. This is less often the case in sarcomas in that both children and adults are treated similarly. However, different types of sarcomas are most typical in these populations, and our understanding of these cancers in one group has provided direction for understanding them in the other group. For example, advances at the molecular level in Ewing sarcoma, a disease that affects predominantly children, helped spearhead the uncovering of several signature translocations in adult sarcomas, such as synovial sarcoma and myxoid liposarcomas. The success of chemotherapy in pediatric sarcomas continues to be a benchmark for adult sarcomas to emulate. Conversely, the demonstration of the viability of limb-sparing surgery combined with adjuvant radiation in adult extremity sarcomas helped advance that treatment approach in pediatric sarcomas. To illustrate some of these concepts and to enhance our understanding of sarcomas across the age spectrum, 4 types of sarcoma are discussed. The first 2 are Ewing sarcoma and rhabdomyosarcoma seen mainly, but not exclusively, in children. The other 2 are synovial sarcoma, which can be looked at as a bridge between pediatric and adult sarcomas as it affects mainly young adults, and liposarcoma that is almost exclusively an adult sarcoma.
