• No contraindications to limb-sparing surgery; patient should be evaluated by a surgeon who specializes in sarcoma resections prior to study enrollment to ensure patient (pt) is a candidate for limb-sparing surgery
• No severe peripheral vascular disease
• Adequate contraception must be used and patients must not be pregnant or breastfeeding; women of childbearing potential and men must agree to use adequate contraception (barrier method of birth control) prior to study entry and for the duration of study participation; men and women should use adequate birth control for at least thirty days after the last administration of sorafenib
• Women of childbearing potential must have negative serum pregnancy test performed within 7-days prior to registration
• 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:

• Patients with known brain metastases; patients with neurological symptoms must undergo a computed tomography (CT) scan/magnetic resonance imaging (MRI) of the brain to exclude brain metastases

• Thrombolic or embolic events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months
• Pulmonary hemorrhage/bleeding event >= CTCAE grade 2 within 4 weeks of first dose of study drug
• Any other hemorrhage/bleeding event >= CTCAE grade 3 within 4 weeks of first dose of study drug
• Serious non-healing wound, ulcer, or bone fracture

• Use of strong cytochrome P450, family 3, subfamily A, polypeptide 4 (CYP3A4) inducers
• Known or suspected allergy to sorafenib or any agent given in the course of this trial
• Any condition that impairs patient's ability to swallow whole pills
• Any malabsorption problem
• Pregnant or lactating women are excluded from this study
• Patients with a "currently active" second malignancy other than non-melanoma skin cancers are not to be registered; patients are not considered to have a "currently active" malignancy if they have completed therapy and considered by their physician to be at less than 30% risk of relapse
