Methods and compositions for the diagnosis for early hepatocellular carcinoma
First Claim
Patent Images
1. A method of determining whether a patient is afflicted with hepatocellular carcinoma (HCC), the method comprising:
- a) determining the level of expression of at least two markers in a patient sample comprising a liver nodule two centimeters or less in diameter, wherein the markers are selected from the group consisting of GPC3, survivin and LYVE1;
b) determining the level of expression of the markers in a control sample;
c) comparing the level of expression of each of the markers in the patient sample and in the control sample; and
d) identifying the patient as being afflicted with HCC when there is a difference between the level of expression of the markers in the patient sample and the control sample, thereby determining whether the patient is afflicted with HCC.

Abstract
Methods and compositions are provide to allow discrimination of dysplastic nodules from early HCC nodules. More specifically, it has been determined that TERT, GPC3, gankyrin, survivin, TOP2A, LYVE1, Ecadherin, IGFBP3, PDGFRA, TGFA, cyclin D1 and HGF are differentially expressed in HCC as compared to normal liver cells and liver cells that have dysplastic, non-cancerous nodules.

17. A method for monitoring the progression of HCC in a patient, the method comprising:
-
a) determining the level or expression of at least two markers in a patient sample comprising a liver nodule two centimeters or less in diameter from a first point in time, wherein the markers are selected from the group consisting of GPC3, survivin and LYVE1; b) determining the level of expression of the markers in a sample comprising a liver nodule of any size from the patient at a subsequent point in time; and c) comparing the levels of expression detected in steps a) and b), thereby monitoring the progression of HCC in the patient, wherein a change in expression of the markers is indicative of either progression or regression of HCC.
