Radiofrequency Ablation in Treating Patients With Refractory or Advanced Lung Cancer

Radiofrequency Ablation of Pulmonary Malignancy

RATIONALE: Radiofrequency ablation uses high-frequency electric current to kill tumor cells. CT-guided radiofrequency ablation may be effective treatment for lung cancer.

PURPOSE: Phase II trial to study the effectiveness of radiofrequency ablation in treating patients who have refractory or advanced lung cancer.

OBJECTIVES:

• Determine the safety and toxicity of radiofrequency ablation in patients with refractory or advanced pulmonary malignancies.
• Determine the efficacy of this treatment, in terms of local control, in these patients.
• Determine whether CT scan is a reasonable imaging assessment tool for treatment delivery and follow-up in these patients.

OUTLINE: Patients undergo percutaneous CT-guided radiofrequency ablation directly to the tumor over 2 hours.

Patients are followed at 1, 3, 6, and 12 months.

PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study.
