Exclusion Criteria

1. ECOG PS >2.

2. Patients who received radiotherapy, chemotherapy, monoclonal antibody and oral EGFR-TKI therapy within three months.

3. Patients who are receiving any other investigational agents within 30 days prior to entering the study.

4. The tumor has metastasized to the brain and / or pia mater.

5. History of other malignancies (except for cured cervical carcinoma in situ or skin basal cell carcinoma and other malignancies that have been cured for more than 5 years).

6. Accompanied by other serious diseases, including but not limited to:

   Uncontrollable congestive heart failure (NYHA grade Ⅲ or Ⅳ), unstable angina, poorly controlled arrhythmia, uncontrolled moderate or above hypertension (SBP > 160mmhg or DBP > 100mmhg) ; Severe active infection; Uncontrollable diabetes (refers to the high fluctuation of blood glucose, the impact on patients' life and the frequent occurrence of hypotension despite the standard insulin treatment and frequent blood glucose monitoring) ; Mental illness affecting informed consent and / or program compliance.

7. Those who are allergic to the drug or its components used in the program.

8. Pregnancy (confirmed by hCG test in blood or urine) or lactating women, or childbearing age subjects are unwilling or unable to take effective contraceptive measures (applicable to both male and female subjects) until at least 6 months after the last trial treatment.

Primary Outcome Measures

Name	Time	Method
Compare objective response rate(ORR) between Chemoradiotherapy Based of Cisplatin + Sintilimab Regimen and Chemoradiotherapy Based of Cisplatin Regimen using RECIST 1.1.	approximately 24 months	ORR was defined as the percentage of participants with confirmed objective tumor response, complete response (CR) or partial response (PR), as determined by investigator using RECIST v1.1 criteria.
Compare Progression Free Survival (PFS) between Chemoradiotherapy Based of Cisplatin + Sintilimab Regimen and Chemoradiotherapy Based of Cisplatin Regimen using RECIST 1.1.	approximately 24 months	PFS was defined as the time between the date of randomization and the date of first documented disease progression or death, whichever occurs first. Disease progression was determined based on investigator assessment using response evaluation criteria In solid tumors (RECIST) v1.1.

Secondary Outcome Measures

Name	Time	Method
Compare Overall Survival (OS) between Chemoradiotherapy Based of Cisplatin + Sintilimab Regimen and Chemoradiotherapy Based of Cisplatin Regimen.	approximately 24 months	Overall Survival (OS) was defined as the time from the date of randomization to the date of death due to any cause. Data for participants who were not reported as dead at the time of analysis was censored at the date when they were last known to be alive.
Compare Disease Control Rate (DCR) between Chemoradiotherapy Based of Cisplatin + Sintilimab Regimen and Chemoradiotherapy Based of Cisplatin Regimen using RECIST 1.1.	approximately 24 months	DCR was defined as the proportion of patients with a documented complete response, partial response, and stable disease (CR + PR + SD).
