Brief summary: This phase II trial studies how well sorafenib tosylate, combination chemotherapy, radiation therapy, and surgery work in treating patients with high-risk stage IIB-IV soft tissue sarcoma. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as epirubicin hydrochloride and ifosfamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x rays to kill tumor cells. Giving sorafenib tosylate, combination chemotherapy, radiation therapy, and surgery may be an effective treatment for soft tissue sarcoma.

Detailed description: PRIMARY OBJECTIVES:

I. To determine the pathologic response rate (\>= 95% necrosis) after preoperative treatment with sorafenib (sorafenib tosylate), epirubicin (epirubicin hydrochloride), ifosfamide, and hypofractionated radiation for high risk soft tissue sarcomas of the extremities or body wall.

SECONDARY OBJECTIVES:

I. To further characterize the safety of sorafenib plus chemoradiotherapy, including wound complication rate.

II. To estimate time-to-event rates, including overall survival, overall disease-free survival, distant disease-free survival, and local disease-free survival in patients with high risk soft tissue sarcomas of the extremities or body wall treated with preoperative sorafenib plus chemoradiotherapy and postoperative sorafenib plus chemotherapy.

OUTLINE:

Patients receive sorafenib tosylate orally (PO) once daily (QD) on days 1-71 and 85-155, epirubicin hydrochloride intravenously (IV) over 3-5 minutes, and ifosfamide IV over 90 minutes on days 15-17, 36-38 (ifosfamide only), 57-59, 99-101, 120-122, and 141-143. Patients undergo external beam radiation therapy (EBRT) on days 36-45 and surgical resection on day 78. Patients with positive margins, undergo EBRT boost on days 91-98.

After completion of study treatment, patients are followed up every 4 months for 2 years, every 6 months for 1 year, and then yearly for 2 years.

Eligibility criteria: Inclusion Criteria:

* Histologically confirmed, soft-tissue sarcoma: excluding rhabdomyosarcoma (pleomorphic rhabdomyosarcoma patients are eligible), Ewing's, primitive neuroectodermal tumor (PNET), osteosarcoma, or gastrointestinal stromal tumor

* Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1
* Patient must sign a study-specific consent form prior to registration
* Ability to understand and the willingness to sign a written informed consent; a signed informed consent must be obtained prior to any study specific procedures

Exclusion Criteria:
