Sarcoma SPOREs
Sarcomas represent a heterogeneous group of cancers that may stem from soft tissue (muscles, fat tissue), bone, cartilage, peripheral nerve sheets, or other connective tissues. Many of these tumors affect children and young adults, accounting for 15% of all pediatric cancers. The incidence for individual sarcoma types is rather low and all sarcoma types combined amount to approximately 13,520 new soft tissue sarcoma cases per year (American Cancer Society data for 2025). The estimated death rate for soft tissue sarcomas in 2025 is forecast to be about 5,420 patients.
