 Thus, in this study, the researchers will investigate whether HRQL can be an important factor in HCC staging system by testing the reliability and clinical validity of FACT-Hep, EORTC QLQ-HCC18, and NFHSI-18. Second, the investigators will evaluate the relation of HRQL with treatment efficacy, recurrence and survival outcome. Lastly, the investigators will suggest the suitable questionnaire module for patients with HCC.
