Treatment is usually multimodal, involving surgery, chemotherapy and radiotherapy: *Surgery, to remove the tumor and a safety margin of healthy tissue. This is the mainstay of<unk>  treatment and is curative in approximately 20–70% of patients, depending on the particular study being quoted. *Conventional chemotherapy, (for example, doxorubicin hydrochloride and ifosfamide), to reduce the number of remaining microscopic metastases. The benefit of chemotherapy in<unk>  to overall survival remains unclear, although a recent study has shown that survival of patients with advanced, poorly differentiated disease marginally improves with doxorubicin/ifosfamide treatment. *Radiotherapy to reduce the chance of local recurrence. The benefit of radiotherapy in this disease is less clear than for chemotherapy.
