title: [Current diagnosis and therapy of soft tissue sarcomas in the adult].
abstract: Soft tissue sarcomas embrace a wide variety of rare tumours. This often means excision without wide margins, and the unexpected malignancy leads to diversity of postoperative treatment. As a rule all lesions of a soft tissue tumour should be biopsied if persisting for more than 6 weeks. The extent of the biopsy is determined by the tumour characteristics, but should not aggravate later resection of a malignant tumour. Preoperative diagnostic studies should be standardised and include MNR, while the tumour is characterised according to the recent edition of the UICC GTNM system. The primary tumour should be excised in a limb-sparing way with wide margins, if necessary including the neighbouring fascia. Local recurrence should be approached aggressively like primary tumours, with curative intention. In cases of distant metastases, which usually occur in the lungs, a grading-associated approach is necessary. In G3 metastases chemotherapy should be administered before the surgical intervention. Radiation therapy is saved for patients in whom the tumour cannot be resected with wide margins or is larger than 10 cm maximum diameter. In the light of current knowledge, radiation therapy should be given as an adjuvant for patients whose tumour was resected without wide margins and for tumours larger than 10 cm in diameter. The use of palliative chemotherapy is still controversial and identification of new prognostic markers for patient selection is necessary. Since most patients with soft tissue sarcoma die from distant metastases and not the primary or locally recurrent tumour, the need for effective chemotherapy in an adjuvant setting is obvious. Controlled studies with as many enrolled patients as possible are necessary if valid data are to be collected. The management of soft tissue sarcoma patients is in principle multidisciplinary and should be confined to specialised centres.
