Soft tissue sarcoma (STS) is a catch-all classification referring to tumours that arise from the embryonic mesoderm and as such can occur anywhere in the body. Surgical resection is the principal treatment for primary localised disease as STS are relatively chemo-insensitive and radiotherapy is more of value in a curative context as an adjunct to surgery. The great variation in anatomic location, factored with variable size and grade, can present significant problems when making a treatment plan.
