Brief summary: Patients with either histological confirmation or clinical diagnosis who are candidate for orthotopic liver transplant(OLT) will receive Sorafenib 400mg 2 x day (BID) as a neoadjuvant (bridging) treatment until transplant. If patient progresses or falls outside of the Milan criteria on sorafenib patient can be treated per physician's discretion using local therapy. Patient will be followed until 30 days after the orthotopic liver transplant (OLT).

Detailed description: Primary objective:

• To evaluate safety (including possible surgical complication) and feasibility of using sorafenib as neo-adjuvant (bridging therapy) prior to orthotopic liver transplant(OLT).

The primary goal of this pilot study is to assess the safety and feasibility of treating HCC patients with sorafenib prior to OLT, as determined by the number of patients experiencing grade 4 hemorrhaging or bleeding post-operatively.

To achieve these goals a 2-stage accrual design will be used with a maximum accrual goal of 10 patients. Initially 5 patients will be entered on-study. If more than one patient experiences grade 4 hemorrhaging/bleeding following OLT the trial will be closed and sorafenib will not be considered safe and/or feasible. If no patient experiences this event 5 additional patients will be enrolled. At the end of the study sorafenib will be considered safe and feasible in this setting if no patient experience grade 4 hemorrhaging/bleeding following transplant. With this design, and assuming at least 3 of the 5 patients in each cohort undergo OLT, the likelihood of stopping early is \<.04 if the underlying risk hemorrhages/bleeding are low (\<5% each) whereas there is a \>.42 chance of early termination if the risks are substantial (e.g. \>.20 likelihood of dose limiting toxicity and \>.30 likelihood of \>grade 4 hemorrhages/bleeding). Overall the likelihood of accepting or not accepting sorafenib as safe and feasible are \>.84, and \<.16, respectively under these conditions.

Secondary objectives:

* Drop out rate
* Time to progression prior to orthotopic liver transplant (OLT)
* Waiting time.

Eligibility criteria: Inclusion criteria:

* Age \> 18 years old
* Confirmation of diagnosis of Hepato Cellular Carcinoma (HCC) and within Milan criteria awaiting liver transplant or going through evaluation for Liver Transplant.
* Either histological confirmation or clinical diagnosis by American Association for the Study of Liver Diseases(AASLD) criteria (see Appendix 1) in cirrhotic subjects is required. For subjects without cirrhosis histological confirmation is mandatory.
* Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1
* Child Pugh A or B (Total point of 7 will be allowed See appendix for scoring system). (ONLY 4 patients with Child Pugh B7 will be allowed.)
* Adequate bone marrow, liver and renal function as assessed by the following:
* Hemoglobin \> 8.5 g/dl
* Absolute neutrophil count (ANC) \> 1,500/mm3
* Platelet count \> 60,000/mm3
* Total bilirubin \< 1.5 times Upper Limits of Normal (ULN)
* ALT and AST \< 2.5 times the Upper Limits of Normal (ULN) ( \< 5 x ULN for patients with liver involvement)
* Creatinine \< 1.5 times Upper Limits of Normal (ULN)
* Women of childbearing potential must have 2 negative serum pregnancy test performed. The first test within 7-10 days prior to the start of treatment. The second test within 24 hours prior to start of treatment.
* 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 should use adequate birth control for at least three months after the last administration of sorafenib.
* 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

* Cardiac disease: Congestive heart failure \> class II New York Heart Association (NYHA). Patients must not have unstable angina (anginal symptoms at rest) or new onset angina (began within the last 3 months) or myocardial infarction within the past 6 months.
* Prior use of sorafenib
* Known brain metastasis. Patients with neurological symptoms must undergo a CT scan/MRI of the brain to exclude brain metastasis.
* Cardiac ventricular arrhythmias requiring anti-arrhythmic therapy.
* Uncontrolled hypertension defined as systolic blood pressure \> 150 mmHg or diastolic pressure \> 90 mmHg, despite optimal medical management.
* Known human immunodeficiency virus (HIV) infection.
* Active clinically serious infection \> CTCAE Grade 2 except for Except Hepatitis B(HBV) or Hepatitis C (HCV)
* Thrombolic or embolic events such as a cerebrovascular accident including transient ischemic attacks within the past 6 months.
* Serious non-healing wound, ulcer, or bone fracture.
* Evidence or history of bleeding diathesis
* Major surgery, open biopsy or significant traumatic injury within 4 weeks of first study drug.
* Use of St. John's Wort or rifampin (rifampicin).
* 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.
