Primary Outcome Measures

Name	Time	Method
Objective response rate	1-year	It refers to the proportion of patients with tumor shrinkage reaching a certain level and maintaining it for a certain period of time, including CR and PR cases.Objective tumor response was assessed using the Response Evaluation Criteria in Solid Tumors (RECIST 1.1 criteria).Subjects must have measurable tumor lesions at baseline, and the efficacy evaluation criteria are divided into complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD) according to RECIST 1.1 criteria.

Secondary Outcome Measures

Name	Time	Method
Disease Control Rate	1-year	Refers to the percentage of CR, PR and SD (≥4 weeks) cases in evaluable patients.
Overall survival	2-year	Refers to the time from the date of patient enrollment to death due to any cause.
Quality of life score	1-year
Adverse events	1-year	Observe the adverse events occurring in all subjects during the clinical study
