Experimental: Magnetic Resonance Imaging
dynamic contrast-enhanced MRI measuring arterial and portal flow
Device: Magnetic Resonance Imaging
Magnetic Resonance Imaging is a radiation free non invasive technique using magnetic radiofrequency waves to image the body. In this study, the research team would like to investigate the possibility of providing functional information on aggressiveness, vascularity and oxygen uptake in liver cancer tumors.
Other Name: MRI
The incidence of hepatocellular carcinoma (HCC) has recently increased in the US mostly due to an increase in chronic hepatitis C infection. Angiogenesis is critical for the growth and metastatic progression of HCC. With the development of new antiangiogenic drugs such as sorafenib, imaging methods to predict and assess therapeutic response beyond changes in size become critical. However, validated imaging methods to predict and assess early HCC response to targeted agents are lacking.
In this study, the investigators would like to develop quantitative MRI methods interrogating different features of HCC tumor biology and pathology, including tumor cellularity, grade, angiogenesis and hypoxia. The investigators propose a multiparametric approach combining advanced DWI (IVIM: intravoxel incoherent motion diffusion measuring perfusion fraction and true diffusion coefficient), DCE-MRI (dynamic contrast-enhanced MRI, which measures arterial and portal flow, mean transit time, blood volume and distribution volume), and BOLD MRI using oxygen or carbogen challenge. This protocol will be performed in patients with HCC undergoing hepatic resection. Routine and advanced histopathologic methods will be performed (tumor grade, CK19 expression, presence of microvascular invasion, VEGF expression, microvessel density, HIF 1-alpha expression). MRI metrics will be correlated with histopathologic metrics.
The first portion of the proposal involves the development of a QC algorithm assessing MR data quality and test-retest. The investigators will propose solutions to improve data acquisition and processing. The last 2 years of the study will be dedicated to a prospective randomized study comparing Yttrium 90 radioembolization to sorafenib, assessing the role of baseline MRI metrics and early changes (at 2 weeks) in these metrics as markers of tumor response and time to progression in patients with unresectable HCC.
