Brief summary: The objective of the study was to evaluate the efficacy and safety of electromagnetic navigation bronchoscopy (ENB) guided microwave ablation (MWA) for the treatment of early-stage peripheral lung cancer.

Detailed description: The study is designed as a multi-center prospective trial with one arm. There will be 5 centers participating the study. Patients diagnosed with early-stage non-small cell lung cancer (NSCLC) that are nonsurgical candidate will be enrolled in the study. Sixty patients are expected to be enrolled in the study. The purpose of the study is to evaluate the efficacy and safety of ENB guided MWA for the treatment of patients with early-stage nonsurgical NSCLC.

Eligibility criteria: Inclusion Criteria:

1. Patients with peripheral lung nodules demonstrated to be NSCLC by pathology with the clinical stage of IA.
2. The length-diameter of the tumors are more than 8 mm and no more than 30 mm.
3. Patients are unsuitable for surgery assessed by multi-modality treatment and agree to the primary treatment of ablation.
4. Patients have good compliance and sign the informed consent.

Exclusion Criteria:

1. Patients cannot receive bronchoscopy for the severe cardiopulmonary dysfunction and other indications.
2. Patients have contraindications of general anesthesia.
3. Chest CT suggests that navigation bronchoscopy technology cannot guide treatment equipment to reach the peripheral lung lesion.
4. Chest CT or bronchoscopy shows that the bronchial lumen occlusion or deformation leading to the guided and treatment equipment cannot reach the peripheral lung lesion.
5. There are large blood vessels or important structures adjacent to peripheral lung lesion.
6. Researchers consider the patient do not fit for the study.
