What this Trial Is About
Researchers are evaluating a shorter course of preoperative radiation therapy for patients with soft tissue sarcoma located in the extremity, trunk, or retroperitoneum. This study aims to examine the safety and effectiveness of delivering radiation over five days, compared to the standard treatment which is spread over 25 days. The trial is a Phase 2 study sponsored by Stanford University focused on improving treatment convenience while monitoring outcomes. Participants receive external beam radiotherapy with a total dose of 30 Gy divided into five daily treatments, each delivering 6 Gy. This abbreviated radiation schedule is given prior to surgery, following the standard care plan of preoperative radiation and surgical resection. The study does not include a comparison group and is not blinded. During the trial, participants are monitored for complications occurring up to 120 days after surgery to assess safety. Researchers also track the rate of local cancer recurrence at 2 and 5 years post-surgery. Patients will undergo regular assessments related to treatment response and side effects to evaluate outcomes. Participation duration includes radiation treatment, surgery, and long-term follow-up for cancer control.
