This phase I trial studies the side effects and best dose of stereotactic body radiation therapy when given together with sorafenib tosylate and bavituximab as first line therapy in treating patients with liver cancer that has spread to other places in the body and cannot be removed by surgery. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as bavituximab, interfere with the ability of tumor cells to grow and spread. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. Giving sorafenib tosylate, bavituximab, and stereotactic body radiation therapy as first line therapy may work better in treating patients with liver cancer.

PRIMARY OBJECTIVES:
I. To evaluate the toxicity and safety of combination treatment with stereotactic body radiation therapy (SBRT) and sorafenib tosylate (sorafenib)/bavituximab in patients with multifocal, unresectable hepatocellular carcinoma (HCC).
SECONDARY OBJECTIVES:
I. To determine tumor response to the combination.
II. To determine progression free survival following SBRT and sorafenib/bavituximab.
III. To determine overall survival following SBRT and sorafenib/bavituximab.
TERTIARY OBJECTIVES:
I. To use the Radiosensitivity Index, 12-gene chemokine signature, and plasma levels of circulating cytokines and correlate with therapeutic response and measure beta2-GP1 and phosphatidylserine (PS)-exosomes levels.
OUTLINE: This is a dose-escalation study of SBRT.
Patients undergo SBRT over 1-2 weeks for a total of 3-5 fractions. Beginning 7 days after SBRT, patients receive sorafenib tosylate orally (PO) twice daily (BID) on days 1-28 and bavituximab intravenously (IV) over 60-90 minutes on days 1, 8, 15, and 22. Courses repeat every 28 days for up to 12 months in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for up to 2 years.
