The purpose of the study is to compare levels of HIF-1 α (Hypoxia Inducing Factor 1-alpha) in patients who have been treated with various types of liver cancer treatments.
In the currently ongoing retrospective aspect of the study, we will obtain pathologic tumor explant specimens from the tumor explant population from 8/1/1994 to 12/31/2005. We will prepare 5-10 slides from each tumor explant block and measure HIF-1α using immunohistochemical staining. We will also be performing a retrospective chart review for specific data points which we believe are needed to assist us in our analysis of the histopathologic specimens. In addition, we will be looking at data in the United Network for Organ Sharing (UNOS) database: www.unos.org, which will allow us to develop a more thorough and robust analysis of the subject's experience with liver cancer. This is a public, mandatory reporting vehicle that the government mandates all transplant centers to report to. Even if the subject was transplanted at Northwestern, and moved, accessing UNOS data will allow us to see what the morbidity/mortality for that patient is. Secondly, we will start enrolling subjects in a prospective fashion. Those that either have been treated, those currently undergoing treatment, or those newly diagnosed. From these subjects we will obtain informed consent to; a) look at the medical records (current, future and retrospective data), b) collect blood specimens for future analysis and correlation with their explant slide data, c) allow us to follow these subjects indefinitely to obtain ongoing outcomes data, morbidity and mortality information.

HIF-1alpha bio-marker
The primary objective is to compare levels of HIF-1alpha expression in HCC tumor explants which have received: 1) no pre-explant embolization; 2) pre-explant Transcatheter arterial chemoembolization (TACE); 3) pre-explant Y90 radio-embolization; 4) pre-explant radiofrequency ablation, or 5) a combination of pre-explant therapies.
Time frame: December 2015
Understand biological behavior of the tumors
Collect blood specimens on those subjects that have had hepatocellular carcinoma, or those currently being treated for it with any of the above mentioned treatments to screen for biomarkers.
