novel mre technique to assess a risk factor for liver cancer

Conditions: NASH - Nonalcoholic Steatohepatitis

Summary: the aim of this proposal is to investigate a novel imaging method to identify patients with non-alcoholic steatohepatitis (nash) who are at risk for hepatocellular carcinoma (hcc).

nash is the most common cause of chronic liver disease, and it is estimated that 40-50% of patients with obesity and t2dm have nash. nash can lead to hcc with the risk increasing 2-3 fold in patient with poor glycemic control. unless caught early, hcc has a poor prognosis with no effective therapies. a unique feature of hcc in nash is that it often arises at a pre-cirrhotic stage, and the prognosis is often dismal. there are no current surveillance strategies for these pre-cirrhotic patients. based on our animal models and pilot patient studies, we developed a novel paradigm that linked liver matrix changes to a more aggressive hcc phenotype. our goal is to develop an imaging-based surveillance tool that will identify early matrix changes that may predispose to hcc.
