For Patients With Early-Stage Non-Small Cell Lung Cancer or Lung Oligo-metastatic Tumor, Applying Pulsed Electric Field Energy Through Percutaneous Approach To Ablate the Tumor and Evaluate the Safety and Initial Efficacy.

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
