title: Preoperative radiation therapy to a complex retroperitoneal soft-tissue sarcoma: a case study.
abstract: Due to their location, retroperitoneal sarcomas tend to present late and with a large size, thus limiting any potential surgical procedure. The inability to achieve local control is the most common cause of treatment failure. This case study describes a challenging example of preoperative radiation therapy for a patient with a retroperitoneal soft-tissue sarcoma. Three-dimensional treatment planning for an asymmetric multibeam arrangement was utilized, with the goal of achieving complete resection at surgery, and thus an improved prognosis, while avoiding high dose to sensitive structures.
