Brief summary: RATIONALE: Sorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as ifosfamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving sorafenib together with ifosfamide may kill more tumor cells.

PURPOSE: This phase II trial is studying the side effects of giving sorafenib together with ifosfamide and to see how well it works in treating patients with high-grade soft tissue sarcoma or bone sarcoma that can be removed by surgery.

Detailed description: OBJECTIVES:

Primary

* Assess the safety, toxicity, and efficacy of neoadjuvant sorafenib tosylate and ifosfamide in patients with resectable high-grade soft tissue or bone sarcoma.

Secondary

* Assess the long-term efficacy or impact of therapy in these patients, in terms of the duration of local recurrence-free survival, distant recurrence-free survival, and disease-specific survival.

OUTLINE:

* Neoadjuvant therapy: Patients receive oral sorafenib tosylate twice daily on days 1-14 in course 1. Patients then receive oral sorafenib tosylate twice daily on days 1-28 and ifosfamide IV continuously on days 1-7 in courses 2 and 3. Treatment repeats every 14-28 days\* for 3 courses.

NOTE: \*Course 1 is 14 days in duration; courses 2 and 3 are 28 days in duration.

* Surgery: At least 1 week after the completion of neoadjuvant therapy, patients undergo surgery.
* Adjuvant therapy: Beginning ≥ 3 weeks after surgery, patients who respond to neoadjuvant therapy receive oral sorafenib twice daily for 6 months. Patients also receive 2 courses of ifosfamide as in courses 2 and 3 of neoadjuvant therapy.

Eligibility criteria: Inclusion Criteria:

* Pathologically confirmed high grade sarcoma of the soft tissue or bone
* participants Identified as a proper candidate for ifosfamide-based neoadjuvant therapy

* Total bilirubin ≤ 1.5 times upper limit of normal (ULN)
* ALT and AST ≤ 2.5 times ULN (≤ 5 times ULN for patients with liver involvement)
* INR \< 1.5 or PT/PTT normal.Concurrent anticoagulation therapy with warfarin or heparin allowed
* Creatinine ≤ 1.5 times ULN
* women of childbearing potential must have negative pregnancy test performed within 7 days prior to start of treatment.
* Fertile patients must use effective contraception during and for ≥ 2 weeks after completion of study therapy.
* A signed informed consent must be obtained prior to any study specific procedures.

Exclusion Criteria:

* known HIV infection

* KNown brain metastases. Patients with neurological symptoms must undergo a CT scan/MRI of the brain to exclude brain metastases.
* any condition that impairs patients' ability to swallow pills
* any malabsorption problem
