Preoperative Percutaneous Radiofrequency Ablation of Primary and Secondary Lung Tumors
- Conditions
- Lung CancerLung Metastasis
- Registration Number
- NCT00610844
- Lead Sponsor
- University Hospital Tuebingen
- Brief Summary
The purpose of the study is to evaluate the effectiveness of radiofrequency ablation by pathological correlation and to characterize the tissue response after treatment of primary and secondary pulmonary tumors.
- Detailed Description
Thermal ablation therapy is an increasingly performed technique in the local tumor treatment. Among these techniques, image-guided radiofrequency (RF) ablation attained widespread consideration in the therapy of liver tumors and osteoid osteoma. Promising results of hepatic RF ablation raised expectations to utilize the advantages of image-guided ablation therapy for the treatment of pulmonary malignancies. The purpose of the study is to evaluate the effectiveness of radiofrequency ablation by pathological correlation and to characterize the tissue response after treatment of primary and secondary pulmonary tumors. Computed tomography-guided RF ablation is performed in local or general anesthesia, followed by surgical resection three days later. An analysis of complete RF ablation and a characterization of tissue response is performed by hematoxylin and eosin staining, immunostaining, and electron microscopy. Adverse effects and complications are recorded.
