Severely abnormal coagulation (INR>1.5) Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects Adequate coagulation function Eligible study subjects must exhibit acceptable liver, renal, and coagulation function as assessed by laboratory tests. Subject has a clinically significant coagulation disorder or disease, defined as a platelet count < 100,000 per microliter or International Normalized Ratio > 1.5 within 4 weeks of surgery; Adequate hematologic, organ, and coagulation within 2 weeks (14 days) prior to randomization. Concurrent anti-coagulation therapy Adequate coagulation functioning within 28 days prior to registration for protocol therapy defined by either of the following criteria: Adequate coagulation Patients on therapeutic dose anti-coagulation with warfarin, low molecular weight heparin (LMWH), or other anti-coagulants will be allowed to participate in the study; however, the anti-coagulants should be held pre- and post- research biopsy (when applicable) as per institutional standards; the risks of a temporary hold of anti-coagulation should be carefully considered and explained to the patient as part of the informed consent process; if it is not felt to be in the best interest of the patient to have anti-coagulation held, the patient may still enter the study, but should not undergo a research biopsy Adequate coagulation parameters (within 21 days prior to registration) International normalized ratio (INR) =< 1.5; patients are eligible if elevated INR is due to anti-coagulation medications and will need to provide documentation of stable coagulation parameters prior to study entry Patients under treatment with anticoagulants or with coagulation disorders or with signs of hemorrhage at baseline Patients with a history of deep vein thrombosis must be on anti-coagulation therapy prior to enrollment; patients requiring prophylactic anti-coagulation are eligible Have adequate coagulation functioning within 15 days prior to start of study treatment, defined by either of the following criteria: Coagulation Patients under treatment with anticoagulants or with coagulation disorders or with signs of hemorrhage at baseline Patients receiving anti-coagulation therapy are excluded Normal coagulation panel.
