Abdominal sarcomas include a wide and varied group of tumours including retroperitoneal leiomyosarcomas and liposarcomas, gastrointestinal stromal tumours arising throughout the gut, and other intra-abdominal and pelvic soft tissue sarcomas. A wide range of surgical expertise is required to treat the full range of tumours encountered, in addition to locally ablative techniques such as radiofrequency ablation, and chemotherapy and radiotherapy. The abdominal sarcoma team includes surgeons from the Royal Free Hospital who are subspecialists and world leaders in their field. Abdominal sarcoma surgery takes place at the Royal Free Hospital whilst oncology treatment remains at UCLH. The two teams work together and discuss patients care at a weekly Abdominal Sarcoma MDT meeting.
