• Eastern Cooperative Oncology Group (ECOG) performance status score is 0 or 1;
• Adequate fresh tumor tissue samples can be obtained for exome and transcriptome sequencing analysis;
• The main organ functions of the heart, liver and kidney are normal:

• Voluntarily sign the informed consent form;
• Aged ≥18 years and ≤75 years, regardless of gender;
• Primary hepatocellular carcinoma confirmed by pathology (histology or cytology);
• Have not received any systemic treatment.
