Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related deaths worldwide, and HCC is more frequently observed in Asia, including South Korea. As HCC is often accompanied by chronic hepatitis B or C virus and liver cirrhosis, treatment of HCC consider not only the tumor but also various factors such as liver function and the patient's performance status. Local treatment and surgery are possible in the early stages of HCC. However, it has a high recurrence rate even after curative surgeries due to underlying cirrhosis and the tumor microenvironment.

Although several studies have investigated gene mutations and differences in treatment response in advanced HCC through next-generation sequencing (NGS), studies on transcriptome analysis of advanced HCC through RNA-sequencing are hard to find, with a need for future research into precise classification and clinical significance of HCC based on multi-omics data.

to establish multi-omics data and discover biomarkers highly associated with treatment response in HCC patients

• Patients who have been diagnosed with unresectable advanced HCC through imaging, histological, or cytological tests.
• Patients who underwent an NGS test with advanced HCC tissues
• Patients who are scheduled to receive systemic treatment
• Patients with measurable lesions based on RECIST v1.1
• ECOG performance status 0 or 1
• Patients with a life expectancy of at least three months

Exclusion Criteria:

• Patients who have systemic conditions accompanied by instability of vital signs, such as infections or organ failure
• Those with mental/neurological conditions or dementia who have difficulties understanding and completing the consent form
• Those who are assessed as not suitable for this study, at the discretion of the researcher

Patients with advanced HCC will be recruited at CHA Bundang Medical Center
