Management of locally advanced primary mediastinal synovial sarcoma

Primary mediastinal synovial sarcoma (PMSS) is a relatively rare disease, and patients are treated predominantly with surgery for resectable disease. Management of locally advanced borderline resectable and unresectable PMSS is not only challenging but also lacks standard guidelines. We present three patients with PMSS, who were unresectable or borderline resectable at presentation and were treated with neoadjuvant chemotherapy followed by surgery and postoperative radiotherapy.
