5. ECOG score of 0 or 1.
6. Females of childbearing age should take appropriate contraceptive measures from screening to 3 months after discontinuation of study treatment and should not breastfeed. The pregnancy test was negative before starting dosing.

5. At the start of the study treatment, there are residual toxicities of the previous treatment that are greater than CTCAE 1 and have not been alleviated, except for alopecia and grade 2 neurotoxicity caused by previous chemotherapy.
6. Any serious or uncontrolled systemic disease, including uncontrolled high blood pressure, active bleeding, active infection including hepatitis B, C, HIV, etc., which the investigator considers unsuitable to participate in the study or affect the trial program compliance.
7. History of ILD, drug-induced interstitial lung disease, radiation pneumonitis requiring steroid therapy, or any evidence of clinically active interstitial lung disease
8. Insufficient bone marrow reserve or organ function.
9. History of hypersensitivity reactions to any active or inactive ingredient of tislelizumab or to drugs that are chemically similar to tislelizumab or in the same class of tislelizumab.
