[Multivisceral and extended resection in tumor surgery. Bone and peripheral soft tissue tumors]

Out of 92 patients with bone sarcoma and 640 patients with sarcomas of soft tissue 45 thoracic girdle amputations and 23 hemipelvectomies were performed. Radical surgery is the most effective prognostic factor. Recurrences stem from unradical operations which fail to include a compartment resection with a mantle of normal tissue in the case of soft tissue sarcomas or a resection of the sarcoma-bearing bone with normal surrounding tissue. Although multimodal therapies often cause tumour regression and necrosis, they do not stop recurrences if even minimal macroscopic parts of tumour have been left in situ.
