A Clinical Study of GP73 as a Hepatocellular Carcinoma (HCC) Tumor Mark

The aims of this study were divided into three parts: 1. To evaluate the sensitivity and specificity of GP73 for the diagnosis of hepatitis B related HCC. Established the standard of GP73 in normal people. 2. To definitude the connections between the GP73 level and various diseases. 3. To find the relations of HCC metastasis and recurrence. Study design: 1. Collectivity type: Prospective，randomized, controlled, multi-central clinical study. 2. Patients: The subjects were from different hospitals including: Peking Union Medical College Hospital (PUMCH), The Cancer Hospital of Peking Union Medical College (PUMC), QiDong Cancer Institute, and Department of Surgery University of Chicago from November of 2007 till the end of this study. Study arrangement: This study was consisted of three parts: 1. Established the standard of normal people and test the sensitivity and specificity of HCC patients. The samples were acquired from Health Screen Center and Department of liver surgery of PUMCH, The Cancer Hospital of PUMC and QiDong Cancer Institute. 2. Extend the study bound, including the hepatitis B virus (HBV) and hepatitis C virus (HCV) carriers. The HBV (+) samples were come from Chinese hospitals and institutions. The HCV (+) samples were provide by the Department of Surgery University of Chicago. 3. Research the relations of serum GP73 level and the other diseases, such as other malignant liver tumors, liver metastatic tumors, liver benign tumor, HCC recurrence following surgery etc.

Inclusion Criteria:

* A group of patients with no history of liver disease, alcohol consumption less than 40g a week, and no risk factors for viral hepatitis were enrolled from the General Internal Medicine clinics. All subjects in this control group were documented to have normal liver biochemistry.
* Consecutive patients with HCC and patients with HBV \& HCV that were age, gender, and race/ethnicity matched to the HCC patients were enrolled from the Liver Clinic during this period. The diagnosis of HCC was made by histopathology, and if histopathology was not available by two imaging modalities (ultrasound \[US\], magnetic resonance imaging \[MRI\], or computed tomography) showing a vascular enhancing mass \>2cm. HBV infection status was based on hepatitis B surface antigen (HBsAg). HCV infection status was based on serum HCV antibody and HCV-RNA positive.
