3. ECOG performance status of 0～2
4. Life expectancy more than 12 weeks.
5. unable or unwilling to undergo chemothraphy
6. Able to understand and sign an informed consent form (ICF).

Exclusion Criteria:

1.

Testing may include the following: HBV DNA, HCV RNA, hepatitis B surface antigen, or anti-Hepatitis B core antibody.
10. Subjects with comorbidities with long-term immunosuppressive drug therapy, or with systemic or local use of immunosuppressive doses of corticosteroids.
11. Subjects who underwent anti-PD-1 /PD-L antibody or anti-CTLA-4 antibody (or any other antibody acting on T cell synergistic stimulation or checkpoint pathway) and anti-angiogenic drugs.
