Neo- and adjuvant chemotherapy is used in high-risk soft tissue sarcoma to improve systemic control. Patients in this trial are treated with 4 cycles of chemotherapy (EIA, etoposide, ifosfamide, adriamycin) preoperatively, followed by local surgery and radiotherapy. An additional 4 cycles of adjuvant chemotherapy is administered. Treatment response is assessed by MRI and CT scans and FDG-PET in a subgroup of patients.
