Outcomes
Primary Outcomes
Immune profile of peripheral blood mononuclear cells (PBMC)
Time Frame: from the date of first study treatment to the date of last study treatment, an average of 3 years
Immune profile of pre-treatment peripheral blood is predictive of sustained responder of radio-embolization, thus predicting the treatment efficacy and toxicities in HCC patients received immunotherapy with or without SBRT
Exosomal PD-L1 level in serum
Time Frame: from the date of first study treatment to the date of last study treatment, an average of 3 years
Increase in level of exosomal PD-L1 may reflect reinvigoration of T-cell activity against cancer cells, thus predicting the treatment efficacy and toxicities in HCC patients received immunotherapy with or without SBRT
Secondary Outcomes
- Serum Cytokine profile(from the date of first study treatment to the date of last study treatment, an average of 3 years)
