Study Summary

This is a study of proton radiotherapy for the pre- or post- operative treatment of patients with extremity sarcoma. This study will treat patients in two dose groups: 1. patients receiving pre-operative proton therapy and 2. patients receiving post-operative proton therapy. In each dose group, the study is divided into two phases. In the first phase of the study, the investigators will determine if treatment with proton therapy is safe and can be delivered on a regular basis. In the second phase, the investigators will determine if proton therapy has less long term side effects compared to standard radiation in both pre-operative patients and post-operative patients.

Primary Outcome

Given this is initially a feasibility study- the primary measure is number of AEs (Adverse Events).
