[Management of soft tissue sarcomas : guidelines for the diagnosis and treatment]

Soft tissue sarcomas determine a rare heterogeneous group of tumours. Most important is the initial diagnostic procedure, comprising adequate imaging and a core needle biopsy. Management should be carried out in sarcoma reference centres. This would mean referring all patients with any suspected soft tissue sarcoma. Prior to surgery, a multidisciplinary conference determines its moment and the eventual need of neoadjuvant treatment. The standard surgical procedure is an "en bloc" excision. This implies removing the tumour in a single specimen with a rim of normal tissue around it.
