In this study, the investigators will detect the expression of HBV-related HCC biomarker lncRNA SNHG15 in tumor tissues and peripheral blood, to explore the specific molecular markers for the early diagnosis of HBV-related HCC.

Paired hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) and adjacent liver tissues were selected, and lncRNA SNHG15 was detected by RT-PCR. At the same time, healthy subjects were selected as the control group, and lncRNA SNHG15 in blood was detected by RT-PCR. At the same time, the correlation between lncRNA SNHG15 and the clinical data of patients, such as diagnosis, pathological grading, recurrence, metastasis and survival time was statistically analyzed.

Inclusion Criteria:

• The age and sex of the healthy control group were matched with that of HBV-associated patient group. There was no tumor in the other parts of the body, and no tumor in the blood system. The healthy control group did not have any liver benign diseases. There are no inflammatory diseases in other parts of the body; the functions of the liver, kidney, and heart were normal.

Exclusion Criteria:

• The volunteer has tumors in the liver or other parts of the body, or blood system tumors; The volunteer has benign liver diseases; The patient has inflammatory disease elsewhere. If the volunteer has any one of the above diseases, it shall be excluded.

No local or systemic treatment was performed before surgery. The patients were finally diagnosed with HBV-related HCC by examination and imaging examination, and the clinicopathologic data were complete.

There is no plan to share individual participant data (IPD) until the project is completed. Sharing IPD may be available 1 year after publication.
