Ground Glass Nodules Less Than 3cm
Conditions
Brief summary
In order to conduct a multicenter comparative effectiveness clinical research of phase II to investigate safety and efficacy of applying microwave ablation in patients with Great-glass lung nodules ≤ 3cm, a single center, non-randomized, open label pilot study is conducted to examine the flexibility, safety and efficacy of using Microwave Ablation in Patients with Ground Glass Nodules that are poor candidate of surgery.
Detailed description
Lung cancer is the most common cancer worldwide contributing 13% of the total number of new cases diagnosed. The main treatments of lung cancer are based on surgical resection and adjuvant postoperative chemotherapy. However, the patients who are intolerant of surgery wouldn't be benefit from surgical resection. Microwave ablation provide new choice for lung cancer, which can effectively treat early lung cancer. The diagnosis of early lung cancer can be based on the results of biopsy of ground-glass nodules (GGNs), which is one of the diagnostic criteria for preoperative diagnosis of early lung cancer. The microwave ablation is the good choice for patients who cannot tolerate surgical resection. However, the flexibility, safety and efficacy of using Microwave Ablation in Patients with Ground Glass Nodules are still unclear.
