Radiofrequency Ablation of Malignant Pulmonary Nodules
December 14, 2015 updated by: Yueyong Xiao, Chinese PLA General Hospital
Efficacy and Safety of Radiofrequency Ablation of Malignant Pulmonary Nodules
The objective of this study is to evaluate the outcomes of radiofrequency ablation in the treatment of patients with malignant pulmonary nodules(not exceed 3cm )who are not suitable candidates for or refuse surgical resection.

Intervention / Treatment
Detailed Description
Percutaneous radiofrequency ablation (RFA) is a minimally invasive technique widely used to treat solid tumors.
Patients with malignant pulmonary nodules will undergo a series of CT- guided percutaneous RFA procedures.
During the procedures,percutaneous needles will be inserted into the target tissues under CT guidance,the needles deliver thermal energy and then destroy the tumors by causing coagulation necrosis via tissue heating.
The purpose of this study is to assess the effectiveness and safety of RFA in pulmonary nodules (maximum tumor diameter ≦30 mm) was 10 mm apart from the big trachea, primary bronchi, esophagus, great vessels,heart and pleura.
Preoperative and postoperative evaluations,including recent laboratory tests evaluated and imaging studies reviewed,will be performed both before and after the procedures.

- With extensive extrapulmonary or intrapulmonary metastasis.
- Have taken anticoagulant as aspirin in one week.
- Target nodules nearby pleura or other important hilum and mediastinum structures.
- With metal implants are adjacent to the target tissues which will be covered with ablation area.

Experimental: radiofrequency ablation
In this group, patients willingly receive CT-guided percutaneous radiofrequency ablation procedures are selected according to the inclusion criteria as follows.
After a series of preoperative evaluation and preoperative preparation,the procedures will be performed under the CT guidance.
CT/MRI scans will be ordered after 24-48 hours to see if there are complications (such as haemorrhage, pneumothorax and pleural effusion).
Regularly follow-up will be carried out for several years after RFA to assess the effectiveness and safety of RFA integratedly.

Percutaneous radiofrequency ablation (RFA) is a minimally invasive technique will be performed in patients with malignant pulmonary nodules in this group.
RFA kills the tumors by causing coagulation necrosis via tissue heating.
The electrode delivers thermal energy will be inserted into the target tissues under the CT guidance to ensure the area of ablation should cover the targets and the lung tissues 0.5-1.0
cm around the tumors.
Post-operative scan and laboratory test will be conducted in time.
