examined before surgery, if they have a brain MRI or CT scan before randomization and
it is confirmed that there is no brain metastasis, they can still be enrolled.

performed: complete resection includes lobectomy, sleeve resection, and bilobectomy;
systemic lymph node dissection includes hilar and mediastinal lymph node dissection Or
sampling, including at least 6 groups of lymph nodes, of which 3 groups are from
intrapulmonary (lobar, interlobar or segment) and hilar lymph nodes, and 3 groups are
from mediastinal lymph nodes including subcarinal lymph nodes; all surgical margins
must be tumor-negative; respectively; The removed mediastinal lymph nodes or the
marginal lymph nodes of the removed lung lobes cannot have extranodal invasion.
6. Postoperative pathologically confirmed NSCLC patients with stage II, IIIA and IIIB
(N2), the disease is staged according to the American Joint Committee on Cancer (AJCC)
8th edition lung cancer staging standard.
7. Confirmed as negative for EGFR/ALK mutation.
8. Complete recovery from surgery during randomization, and complete postoperative wound
healing must be achieved after any surgery;
9. The Eastern Cooperative Oncology Group (ECOG) physical status (PS) score is 0 or 1 and
has not deteriorated 2 weeks before the first administration of the study drug, and
the minimum expected survival is greater than 12 weeks.

measures (Appendix K) and should not breastfeed from signing informed consent to the
end of the study medication within 6 months (whichever occurs later); male patients
are effective from signing informed consent Willingness to use barrier contraception
(i.e. condoms) within 6 months of the end of sexual evaluation/study medication
(whichever occurs later).
12. Female patients have a negative blood pregnancy test result within 7 days before
randomization, or meet one of the following criteria to prove that there is no risk of
pregnancy:
1. Postmenopausal is defined as amenorrhea at least 12 months after the age is
greater than or equal to 50 years and all exogenous hormone replacement therapy
is stopped;
2. Women younger than 50 years old, if you stop all exogenous hormone treatments and
have amenorrhea for 12 months or more, and the levels of luteinizing hormone (LH)
and follicle stimulating hormone (FSH) are within the reference range of
postmenopausal laboratory Can be considered post-menopausal;
3. Have received irreversible sterilization, including hysterectomy, bilateral
ovarian removal, or bilateral fallopian tube resection, except for bilateral
tubal ligation.
Exclusion Criteria:
1. Unresectable or metastatic disease, pathology report showing positive surgical margins
or extranodal invasion under the microscope, or leftover lesions during surgery.
2. Patients with lung adenocarcinoma with clear EGFR mutation or ALK rearrangement.
3. Upper sulcus lung cancer.
4. Only patients undergoing segmental resection or wedge resection.
5. Because NSCLC has previously received any anti-cancer treatment other than surgery,
including preoperative and postoperative chemotherapy, radiotherapy, targeted therapy
(such as small molecule tyrosine kinase inhibitors targeting EGFR, VEGFR and other
pathways, monoclonal Antibodies, etc.), immunotherapy, research therapy, etc.; within
14 days before the first administration of the research drug, Chinese medicines and
Chinese medicine preparations with anti-tumor therapy indications or tumor adjuvant
therapy effects have been used;
6. Suffered from other malignant tumors before the start of the trial, except for the
following medical history:
- Malignant tumors that have been cured, have been inactive for more than 5 years
and have a very low risk of recurrence before being selected for the study;
- Adequately treated non-melanoma skin cancer or malignant lentigines with no
evidence of disease recurrence;
- Carcinoma in situ with adequate treatment and no evidence of disease recurrence;
- Localized prostate cancer after radical surgery.
7. Complicated with unstable systemic diseases, including active infections, uncontrolled
hypertension (systolic blood pressure =140 mmHg or diastolic blood pressure =90 mmHg),
unstable angina pectoris, attacks that have started within the last 3 months Angina
pectoris, congestive heart failure (= New York Heart Association [NYHA] level II),
myocardial infarction (6 months before enrollment), severe arrhythmia requiring
medication, liver, kidney or metabolic diseases;
8. Active, known or suspected autoimmune diseases, or autoimmune paraneoplastic syndromes
that require systemic treatment;
9. Subjects who have used corticosteroids (>10 mg/day of prednisone or other equivalent
hormones) or other immunosuppressive agents for systemic treatment within 2 weeks
before the first administration. In the absence of active autoimmune diseases, inhaled
or topical corticosteroids are allowed, and adrenal hormone replacement therapy with a
dose of =10 mg/day prednisone is allowed;
10. Have significant clinically significant bleeding symptoms or obvious bleeding tendency
within 1 month before the first administration, such as gastrointestinal bleeding,
gastric ulcer bleeding, active hemoptysis or vasculitis.
11. Arteriovenous thrombosis, such as deep vein thrombosis, pulmonary embolism, etc.
occurred within 3 months before the first administration (except for implantable
venous port, catheter-derived thrombosis or superficial venous thrombosis, these cases
