Most soft tissue sarcomas arise in an arm or leg. Limb-saving surgery with radiotherapy cures most localised tumours and is as safe as amputation. For spread disease doxorubicin is the backbone: adding ifosfamide shrinks more tumours without lengthening life, and in leiomyosarcoma adding trabectedin doubles the time the disease stays controlled.
Extremity soft tissue sarcoma is the stage and site framework for the histology-specific records: undifferentiated pleomorphic sarcoma, liposarcoma, leiomyosarcoma, synovial sarcoma, myxofibrosarcoma, MPNST and others. Risk is set by FNCLCC grade, size and depth, and prognostic tools such as Sarculator translate these into individual estimates. The Rosenberg NCI trial of 1982 established that limb-sparing surgery with radiotherapy gives the same survival as amputation, and the NCIC SR2 trial of 2002 showed preoperative radiotherapy (50 Gy) and postoperative radiotherapy (66 Gy) give equal local control, with more acute wound complications after preoperative treatment but less late fibrosis, oedema and joint stiffness, which is why preoperative radiotherapy is now preferred for large deep tumours.
Perioperative chemotherapy has been contested for decades: the EORTC 62931 adjuvant trial was negative, but the Italian Sarcoma Group ISG-STS 1001 trial found that three cycles of neoadjuvant full-dose epirubicin-ifosfamide improved relapse-free and overall survival in high-risk limb and trunk sarcoma compared with histotype-tailored regimens, and it is offered to fit patients with large, deep, high-grade tumours. Isolated limb perfusion and regional hyperthermia with chemotherapy are used in selected centres to make unresectable tumours operable.
| Setting | Approach | Guideline |
|---|---|---|
| Localised, resectable | Limb-sparing wide resection with preoperative (50 Gy) or postoperative (66 Gy) radiotherapy for high-grade or deep tumours over 5 cm; surgery alone for small superficial low-grade tumours. | not mapped |
| High-risk localised (large, deep, high grade) | Neoadjuvant anthracycline-ifosfamide (ISG-STS 1001) in fit patients; regional hyperthermia with chemotherapy or isolated limb perfusion for borderline resectable tumours. | not mapped |
| Advanced, first line | Doxorubicin alone, or doxorubicin plus ifosfamide when shrinkage is needed (EORTC 62012); doxorubicin plus trabectedin for leiomyosarcoma (LMS-04); olaratumab withdrawn after ANNOUNCE. | not mapped |
| Later lines and oligometastatic | Gemcitabine-docetaxel, pazopanib, trabectedin, eribulin (liposarcoma); pulmonary metastasectomy or stereotactic radiotherapy for limited lung disease; histology-directed agents and trials. | not mapped |
