Detailed DescriptionPRIMARY OBJECTIVES:
I. To determine the feasibility and toxicity of proton radiotherapy for retroperitoneal sarcomas.
II. To determine the maximum safe proton radiotherapy dose for retroperitoneal sarcomas.
III. To determine the maximally tolerated dose of proton radiotherapy for patients with potentially resectable retroperitoneal sarcoma. (Pre-operative cohort) IV. To assess acute side effects from irradiation using proton beam therapy and dose/volume constraints that are derived from conventional radiotherapy. (Postoperative cohort)
I. To assess the clinical effectiveness of proton radiotherapy for retroperitoneal sarcoma.
II. To determine the long-term toxicity of proton radiotherapy to the abdomen and pelvis region.
III. To monitor for effects of proton treatment on tumor and normal tissues using radiographic imaging (both cohorts) or ex-vivo analysis of tissue samples (preoperative cohort only).

Patients undergo proton beam radiotherapy 5 days a week for 6 (preoperative patients) or 8 (post-operative patients) weeks in the absence of disease progression or unacceptable toxicity.
Radiation: Proton Beam Radiation Therapy
- Feasibility [ Time Frame: One year ]Feasibility of pre-operative and post-operative proton radiation therapy
- Acute toxicity as assessed by NCI CTC Version 3.0 [ Time Frame: Within 60 days of completion of radiotherapy ]
- Late toxicity as assessed by the RTOG/EORTC late morbidity scoring system [ Time Frame: After 60 days of therapy ]
- Clinical efficacy [ Time Frame: One year ]Local recurrence-free survival, distant metastasis-free survival, and overall survival
