Prospective, multi-center, phase II clinical trial. The study plans to enroll 146 patients with multiple lung cancers. After signing the informed consent, they were screened to meet the admission and discharge criteria, and received microwave ablation treatment. Electromagnetic navigation bronchoscope-guided intrapulmonary microwave ablation or percutaneous microwave ablation was selected according to the patient's wishes and the evaluation of the surgeon. After the operation, they were randomized and the experimental group accepted PD-1 immune checkpoint inhibitor treatment (microwave ablation combined with Camrelizumab treatment does not exceed 16 cycles, or disease progression/worsening or confirmed imaging disease progression, or withdrawal for any reason), the control group does not After receiving any treatment, the two groups were followed up closely (36 months after the last treatment, including safety follow-up and survival follow-up).

Multiple pulmonary nodules diagnosed by CT, the number of target lesions 2 and 5 (definition of target lesions: the largest diameter of a single nodule 8 mm or the largest diameter of a solid component 5mm, and the largest single nodule Diameter 30 mm), the target lesions are distributed in at least two lung lobes
The target lesions need to be pathologically indicated as lung cancer, and at least one of the target lesions is pathologically diagnosed as lung cancer (at least one target lesion is pathologically diagnosed as lung cancer, and the CT follow-up after anti-inflammatory treatment for the remaining target lesions is clear and stable for no less than 3 months, which is also consistent with the entry Group conditions)
The patient has no lymph node metastasis, lung metastasis or distant organ metastasis (N0, M0)
ECOG PS score 0-2
Expected survival time 12 months
Sufficient hematology function, defined as absolute neutrophil count 1.5109/L, platelet count 80109/L, hemoglobin 90g/L (no history of blood transfusion within 7 days, no G-CSF and others Correction of hematopoietic stimulating factors)
Sufficient liver function, defined as all patients with total bilirubin level 1.5 times upper limit of normal (ULN) and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels 2.5 times ULN
Sufficient renal function, defined as creatinine clearance 50ml/min (Cockcroft-Gault formula)
The coagulation function is adequate, defined as the international normalized ratio (INR) or prothrombin time (PT) 1.5 times ULN; if the subject is receiving anticoagulation therapy, as long as the INR/PT is within the proposed range of anticoagulation drugs Can
For female subjects of childbearing age, the urine or serum pregnancy test should be negative within 3 days before receiving the first study drug administration. If the urine pregnancy test result cannot be confirmed as negative, a blood pregnancy test is required
If there is a risk of conception, male and female patients need to use high-efficiency contraception (that is, a method with a failure rate of less than 1% per year) and continue until at least 180 days after stopping the trial treatment
Subjects voluntarily join the study and sign written informed consent before any trial-related procedures are implemented. They have good compliance and cooperate with follow-up

Exclusion Criteria

Any systemic anti-tumor treatment before tumor ablation, including interventional chemoembolization, radiotherapy, chemotherapy, targeted therapy, or Chinese patent medicine with anti-tumor indications or immunomodulatory drugs (thymosin, interferon, interleukin, etc.) ), or received major surgery within 3 weeks before the first intervention
Have received the following therapies in the past: anti-PD-1, anti-PD-L1 or anti-PD-L2 drugs or drugs that stimulate or synergistically inhibit T cell receptors (for example, CTLA4, OX-40, CD137)
There are multiple factors that affect surgery or ablation (such as coagulation dysfunction, immune system disease, etc.)
