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