Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Major pathologic response rate(MPR)(<10% viable tumor cells) | To assess the major pathologic response rate (<10% viable tumor cells) in patients receiving Sintilimab Injection | At time of surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Disease Control Rate (DCR) | the proportion of patients with a best overall response of CR, PR or SD in the whole body, as assessed per RECIST 1.1 by the investigator. | up to 2 years | 
| Overall response rate (ORR) | the proportion of patients with a best overall confirmed response of CR or PR in the whole body as assessed per RECIST 1.1 by the investigator | up to 2 years | 
| Disease-free survival (DFS) | Defined as the time from date of surgery until recurrence of tumor or death from any cause | up to 2 years | 
| Incidence of irAEs | Immune-related AE per Common Terminology Criteria for Adverse Events (CTCAE V5.0) | up to 2 years | 
| Incidence of SAEs | Grade 3 or higher per Common Terminology Criteria for Adverse Events (CTCAE V5.0) | up to 2 years |
