Summary

The aim of the present study is to validate the uptake of novel, positron emitting radiotracer, 68Gallium Citrate in hepatocellular carcinoma(HCC). The investigators also aim to evaluate the sensitivity of 68Gallium (68Ga)-citrate positron emission tomography/computed tomography (PET/CT) for the identification of intrahepatic HCC lesions in comparison with existing modalities: computed tomography (CT) alone and magnetic resonance imaging (MRI). The investigators expect that 68Ga-citrate PET/CT will offer a sensitive functional imaging modality for identification of HCC lesions in the liver. The investigators intend to use the results of this preliminary study to fuel further studies in the utility of 68Ga-citrate PET/CT for HCC treatment monitoring.

Detailed description

Hepatocellular carcinoma (HCC) is a malignancy of the liver with very high mortality. Management of HCC often involves interventional and surgical therapies that distort surrounding liver morphology. For this reason, current morphologic imaging techniques following these therapies often fail to distinguish between residual tumor and post-therapeutic morphologic changes. Therefore, there is the need for an effective imaging technique in therapy monitoring for HCC. Functional imaging techniques are commonly used in other cancers for effective therapy monitoring. Functional imaging in HCC with single photon emitting gallium radioisotopes has been explored in the past but have not been used routinely due to poor resolution of images. 68Gallium-citrate PET/CT can generate high resolution images that specifically target HCC cells regardless of liver morphology. This makes 68Gallium-citrate PET/CT an ideal imaging modality for HCC following therapies that distort liver morphology. Before determining its efficacy in therapy monitoring, The investigators aim to demonstrate the ability for 68Gallium-citrate PET/CT to localize known intrahepatic HCC lesions. In this pilot study, 18 subjects with newly diagnosed HCC will be recruited. Each subject will undergo a 68Gallium-citrate PET/CT scan within 6 weeks of radiographic diagnosis. Foci of abnormal radiotracer uptake on these scans will be tabulated and compared to clinically-indicated morphologic imaging. The investigators expect that 68Gallium-citrate PET/CT will offer a sensitive functional imaging modality for identification of HCC lesions in the liver. The investigators intend to use the results of this preliminary study to form the basis for grant applications to extra-mural funding agencies. These subsequent grant applications will focus on further studies in the utility of 68Gallium-citrate PET/CT for HCC therapy monitoring and metastatic work-up.
