Inclusion Criteria: 1. Signed informed consent and voluntarily enrolled in this study; 2. Histologically or cytologically confirmed extensive-stage small cell lung cancer; 3. Patients with other types of advanced solid tumors confirmed by histology or cytology; patients who, based on currently available data, the investigator believes may benefit from adebrelimab treatment may also be considered for enrollment; 4. Patients in Cohort 1 who experience disease progression and whose second-line treatment options, as assessed by the investigator, include adebrelimab in combination therapy may be enrolled in Cohort 2; 5.
