Brief summary
RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying the side effects of intensity-modulated radiation therapy and to see how well it works in treating patients undergoing surgery for stage IB, stage II, or stage III soft tissue sarcoma.
Detailed description
OBJECTIVES: Primary * Estimate the wound complication rate in patients with stage IB-III soft tissue sarcoma (STS) treated with neoadjuvant intensity-modulated radiotherapy (IMRT). Secondary * Assess local control rate in patients treated with this regimen. * Assess metastatic failure rate in patients treated with this regimen. * Assess disease-free survival of patients treated with this regimen. * Assess overall survival of patients treated with this regimen. * Assess function and general health in these patients using the Musculoskeletal Tumor Society rating scale, Toronto Extremity Salvage Score, and the Short-Form 36. * Determine changes in STS gene expression after IMRT by microarray analyses. * Correlate, preliminarily, changes in STS gene expression with pathological and clinical outcomes. OUTLINE: Patients undergo intensity-modulated radiotherapy (IMRT) once daily 5 days a week for 5 weeks in the absence of disease progression or unacceptable toxicity. Patients then undergo surgery \> 1 month after completion of IMRT. Tumor tissue samples are collected at baseline and at the time of surgery for correlative laboratory studies. Samples are analyzed for gene expression by RNA microarray, real-time polymerase chain reaction, and western blotting. After completion of study treatment, patients are followed periodically for 2 years.

Outcome results
Wound Complication Rate
Major wound complications up to 4 months post surgery include: Complications requiring a secondary operation under general or regional anesthesia for wound care. Seroma aspiration. Drain placement.
