[Surgery of soft tissue sarcoma (with the exception of the retroperitoneum)].

The place of surgery in the treatment of soft-tissue sarcoma is defined in the light of a review of the recent litterature. Usual treatment combines conservative surgery and radiotherapy. The essential risk factor of local recurrence is the quality of surgical resection, defined by the definitive resection margins. The addition of radiotherapy after inadequate surgery can improve local control, but cannot ensure that obtained after adequate surgery. Some limited tumours can be treated by surgery alone, but radiotherapy remains essential in more advanced tumours. Under these conditions, local recurrence rates after surgery alone, surgery and systematic radiotherapy and surgery with radiotherapy, as required are 27%, 28% and 30% respectively. The development of a local recurrence appears to affect survival in tumour with a good initial prognosis, early recurrence determining unfavourable outcome. Serious postoperative morbidity is observed in 14% of the cases and is responsible for delayed treatment and functional disorders. The use of muscle flaps to fill the surgical defects can reduce these complications. Evaluation of the functional results must be based on predefined objective criteria.
