Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Anlotinib In Combination With Durvalumab<br> | Drug: Anlotinib In Combination With Durvalumab<br>* At the end of chest radiotherapy (c2d1), the simultaneous administration of androtinib hydrochloride capsule and PD-1 / L1 inhibitor was started. L Arotinib hydrochloride capsule, 12 mg, Po, QD, was taken orally for two weeks, one week, three weeks as a cycle, completed in the first 14 days until the disease progress; Durvalumab injection, 1500mg, IV, once every three weeks, completed on the first day until the disease progresses. Tetraprizumab injection, 240mg, IV, once every three weeks, completed on the first day until the disease progresses. The choice of durvalumab / trepril mAb was at the discretion of the researchers.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| progress free survival(PFS) | the period from the beginning of treatment to the observation of disease progress or death for any reason | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall survival(OS) | Time from randomization to death for any reason. The last follow-up time is usually calculated as the time of death for the subjects who have lost the visit before death | 1 year |
