## Overview[edit | edit source]

Soft tissue sarcomas are relatively uncommon cancers. They account for less than 1% of all new cancer cases each year.[1]

## Epidemiology[edit | edit source]

### Incidence[edit | edit source]

* The estimated number of new cases of soft tissue sarcoma in the United States is approximately 12,000.[2]

* The estimated incidence of soft tissue sarcoma worldwide is 1.8 to 5 per 100,000 per year.[3]

### Age[edit | edit source]

Soft tissue sarcomas are more commonly found in older patients (>50 years old) although in children and adolescents under age 20, certain histologies are common (rhabdomyosarcoma).

### Percent Distribution of Soft Tissue Sarcoma by Histology[edit | edit source]

* Fibrosarcoma: 6.9%
* Infantile fibrosarcoma: 0.2%
* Fibrous histiocytoma, malignant: 9.2%
* Dermatofibrosarcoma: 3.6%
* Liposarcoma: 17.1%
* Leiomyosarcoma: 13.2%
* Rhabdomyosarcoma: 3.1%
* Embryonal rhabdomyosarcoma: 1.3%
* Hemangiosarcoma: 3.7%
* Hemangiopericytoma, malignant: 0.5%
* Kaposi sarcoma: 0.8%
* Malignant peripheral nerve sheath tumor: 1.6%
* Malignant neurilemmoma: 0.2%
* Neuroblastoma: 0.6%
* Synovial sarcoma: 4.8%
