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.
