Things I found when searching for cancer stage iii soft tissue sarcoma.
PURPOSE: This phase I trial is studying the side effects and best dose of celecoxib when given together with radiation therapy in treating patients with stage II or stage III soft tissue sarcoma of the arm, hand, leg, or foot that has been removed by surgery. 
In the absence of universally accepted treatment guidelines for stage II and III soft tissue sarcomas, a multidisciplinary approach can help determine which combination of surgery, radiation therapy, and chemotherapy will benefit each individual patient. Patel said, but this is clearly inadequate because we know that up to half of patients with stage III soft tissue sarcoma will have a recurrence and will die of the disease within 35 years.
