Radiofrequency Ablation of Lung Tumors

Phase 2

Completed

• Conditions: Lung Cancer; Metastasis

• Registration Number: NCT00180856
• Lead Sponsor: Gustave Roussy, Cancer Campus, Grand Paris

Brief Summary

Radiofrequency ablation has achieved impressive results in the treatment of unresectable primary and metastatic liver cancer. Animal studies have demonstrated that radiofrequency can fully ablate lung tumors in animal models. We set up a prospective study to evaluate the local efficacy of radiofrequency ablation of lung neoplasms. The aim of the study is to prospectively evaluate local efficacy with a minimal follow-up of one year, tolerance, lung disease-free survival and survival after radiofrequency ablation of lung tumors (primary lung cancer or lung metastases).

Detailed Description

Radiofrequency (RF) ablation has achieved impressive results in the treatment of unresectable primary and metastatic liver cancer. Animal studies have demonstrated that RF can fully ablate lung tumors in animal models. We set up a prospective study to evaluate the local efficacy of radiofrequency ablation of lung neoplasms with a minimal follow-up of one year. The primary endpoint was to determine the rate of incomplete local treatment at 1 year. The secondary endpoints were to evaluate tolerance, survival, disease-free survival and lung tumor-free survival. Patients are followed-up by CT scan examination at day 1 or 2 before discharge from the hospital, then at 2, 4, 6, 9 and 12 months and then at 2 years
