Brief Summary
The goal of this observational study is to evaluate the performances of a percutaneous Pulsed Electrical Field (PEF) ablation to treat patients with primary early-stage lung cancer (NSCLC) or lung oligometastatic Tumors who are unresectable or refusal surgery/Radiotherapy. The main questions the study aims to answer are: The safety and technical feasibility of the PEF ablation. The preliminary efficacy of the PEF ablation for target lesion in lung Patients who meet the inclusion/exclusion criteria will be given percutaneous PEF ablation to the target lesions under general anesthesia. Then follow-up to 12 months to monitor any progression by about 3 months interval. Target Subject: Patients with early-stage primary non-small cell lung cancer(NSCLC) or pulmonary oligometastatic tumors who are not surgical resectable or unsuitable for surgery/radiotherapy

Eligibility Criteria
You may qualify if:
- Age ≥18 years but ≤ 79 years, male or female
- Pathologically diagnosed primary NSCLC and stage IA, or oligometastatic lung tumors that primary cancer has been controlled. the maximum diameter of the lesion is ≤3cm, (Pathological diagnosis includes conventional pathological examination or ROSE rapid on-site evaluation)
- For multiple primary lung cancers, the number of lesions is ≤3 and the maximum diameter of the lesion(s) is ≤3cm. For metastatic tumors, the number of lesions in one side of lung is ≤3 (total lesions in both sides \<5), the maximum diameter of the lesion(s) is ≤3cm.
- ECOG score ≤ 2;
- Expected survival ≥ 12 months;
- Clinical assessment as unsuitable for surgical resection or refusing surgery and radiotherapy.
- Assessed by an anesthesiologist as suitable for general anesthesia;
- Agree to receive ablation therapy and sign the informed consent form.
You may not qualify if:
- Received any form of local tumor therapy for the target lung tumor lesion(s) within 6 months.
- Currently receiving systemic anti-tumor therapy, such as chemotherapy, targeted therapy, immunotherapy etc.
- (For pulmonary oligometastatic tumors with primary cancer controlled already, if systemic anti-tumor therapy still needs to be continued, it is acceptable. For primary NSCLC patients, according to guideline recommendations, no concurrent systemic anti-tumor therapy is indicated).
- The distance between tumor lesion edge and important structures such as heart, diaphragm and mediastinum is less than 10mm.
- With a history of hypersensitivity to medications to be used in general anesthesia or drugs required during the procedure/follow-up (such as contrast-enhanced CT scan).
- Anemia (Hemoglobin (HGB) \< 9 g/dL), dehydration, and severe metabolic disorders that cannot be improved or well managed in the short term.
- Coagulation abnormalities (INR \>1.5 or APTT \>1.5 ULN), or platelet count below 90 x 10\^9/L.
- Uncontrolled lung or systemic infection. Or uncontrolled skin infection at the puncture site or fever \> 38.5°C.
- Currently using anticoagulant therapy and/or antiplatelet drugs (such as warfarin, dabigatran, rivaroxaban, and other new oral anticoagulants) and have not been discontinued for more than 5 to 7 days prior to ablation therapy.
- Receiving high-dose immunosuppressive drugs (prednisone exceeding 10mg/day or equivalent). If discontinued for more than 4 weeks, it is acceptable.
- Subject has comorbidity of severe other lung diseases (including interstitial pneumonia, pulmonary fibrosis, severe emphysema or atelectasis) and unsuitable for enrollment with the judgement of the investigator.
- Malignant pleural effusion on the treatment side of lung.
- Severe uncontrolled hypertension, diabetes, severe abnormal liver or kidney function, or heart failure that investigator assessed as unsuitable for enrollment.
- Acute cardio-cerebrovascular events within 3 months, such as acute hemorrhagic or ischemic stroke, acute coronary syndrome, acute myocardial infarction.
- Psychiatric disease that not well controlled.
