"Treatment and prognosis "
"History and etymology "
"Radiation-induced sarcoma has a poor prognosis compared to primary sarcomas: the 5-year-survival rates vary from 17-58% in radiation-induced sarcoma compared with 54-76% in patients with sporadic sarcomas. Some unfavourable factors related to radiation-induced sarcomas are central tumour site, incomplete surgical remission, microscopic tumour necrosis, and the presence of metastases, the two former factors which are overrepresented in radiation-induced sarcoma 3."
"low-grade tumours and high-grade tumours with 5 cm or smaller: usually treated with a margin-negative surgical excision and systemic chemotherapy is considered when a negative margin is not certain"

"The study also found a higher risk of radiation-induced sarcoma among younger patients through a link between a particular cancer type that is more common among the young 2. There is a direct correlation with the risk and the radiation doses 4."
