A group of patients with adult-type soft tissue sarcoma is at high risk of local recurrence and distant metastases. Age, tumour site, histological subtype, tumour size and grade have been identified as the most important independent adverse prognostic factors. Macroscopically complete tumour resection is considered as the mainstay of treatment with the addition of preoperative or postoperative radiotherapy for extremity or trunk localisation. Retroperitoneal localisation requires compartmental resection and is associated with a worse prognosis. Here, radiotherapy is of no proven value. Perioperative chemotherapy is considered to treat micrometastatic disease not detectable at the time of diagnosis. The neoadjuvant application gives the risk of distant metastasis the greatest importance as therapy is carried out at the earliest possible time, whereas adjuvant chemotherapy is delayed by surgery and the necessary wound healing. With reported response rates up to 30%, both the operability may be improved and the risk of intraoperative tumour cell dissemination may be reduced, resulting also in reduced local relapse rates. However, the potential risk of early tumour progression may counteract this benefit. Optimised strategies with multimodality approaches including chemotherapy, regional hyperthermia (RHT) and immunotherapeutic agents have been shown to improve survival in high-risk patients. Here, we focus on the data from available randomised studies investigating the use of perioperative chemotherapy in patients with high-risk adult-type soft tissue sarcoma, including the use of RHT for local enhancement of chemotherapy effect and immune induction.
