Contraception: Women of reproductive age should agree that they must use effective contraception during and for 6 months after the study; Had a negative serum or urine pregnancy test within 7 days before study enrollment and had to be non-lactating; Men should agree to use contraception during the study and for 6 months after the end of the study

Exclusion Criteria:

1. Allergic to treatment drugs;

2. EGFR/ALK mutation positive;

3. There are high risk factors for local treatment complications such as bleeding, fistula and perforation;

4. Patients with pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-induced pneumonitis and severe pulmonary function impairment (maximum volume < 40%);

5. Patients with coagulopathy who have severe bleeding tendency and cannot be corrected in a short time (prothrombin time >18 s, prothrombin activity <40%);

6. Anticoagulant therapy and/or antiplatelet drugs (except dabigatran, rivaroxaban and other new oral anticoagulants) were stopped for no more than 5 to 7 days before ablation.

7. Extensive pleural metastases with massive pleural effusion;

8. Patients with active brain metastases: untreated, newly diagnosed and/or growing lesions or symptomatic brain metastases (patients with stable symptoms after treatment of brain metastases were eligible to remain stable for at least 4 weeks);

9. Infection and radiation inflammation around the lesion, skin infection at the puncture site without good control, systemic infection, high fever >38.5 ℃;

10. Subjects with active autoimmune disease or a history of autoimmune disease, or active hepatitis B/C. Note: Subjects with hepatitis B who met the following criteria were also eligible for inclusion: The HBV viral load must be less than 104 copies per milliliter (2000IU per milliliter) before the first dose, and subjects should receive anti-hbv therapy to avoid virus reactivation throughout the study drug treatment. For subjects with anti-HBC (+), HBsAg (-), anti-HBs (-), and HBV viral load (-), prophylactic anti-HBV therapy is not required, but close monitoring of viral reactivation is required；

11. Patients were using immunosuppressive agents or systemic hormone therapy (dose >10mg/ day prednisone or other efficacy hormone) to achieve immunosuppression and continued to use them within 2 weeks before enrollment;

12. Has had or is currently suffering from other malignant tumours within 5 years, except cured cervical carcinoma in situ, non-melanoma skin cancer or other tumours/cancers that have undergone radical treatment and have shown no signs of disease for at least 5 years; 65/5000

13. Had received antitumor drug therapy (e.g., chemotherapy, hormone therapy, immunotherapy, antibody therapy, radiotherapy, etc.) 4 weeks before or within 4 weeks of the first dose, with the exception of palliative radiotherapy to bone for pain relief;

14. Had undergone major surgery within 4 weeks before the first dose or was expected to undergo major surgery during the study;

15. Patients whose imaging showed that the tumor had invaded important blood vessels or who were judged by the investigator to be highly likely to invade important blood vessels during the subsequent study and cause fatal massive bleeding;

16. Clinically significant cardiovascular disease, including but not limited to acute myocardial infarction, severe/unstable angina pectoris, or coronary artery bypass grafting within 6 months before enrollment; New York Heart Association (NYHA) grade of congestive heart failure ≥2; Arrhythmia (including QTc interval ≥ 450 ms in men and ≥ 470 ms in women); Left ventricular ejection fraction (LVEF) <50%;

20. The subject has received or plans to receive solid organ or blood transplantation (except corneal transplantation) during the study;

21. Patients deemed ineligible for enrollment in the investigator's judgment;
