Tumor tissue biomarker detection results must meet the following conditions at the same time: (1)EGFR mutation negative.(2)ALK rearrangement negative.(3)There are sufficient tissue samples for PD-L1 detection
Aged ≥ 18 years and ≤ 75 years
ECOG (Eastern Cooperative Oncology Group) performance status ≤ 1
Life expectancy of more than 3 months
Have adequate organ function as indicated by the following laboratory values
