RATIONALE: Radiofrequency ablation uses high-frequency electric current to kill tumor cells. Computed tomography (CT)-guided radiofrequency ablation may be an effective treatment for non-small cell lung cancer.

PURPOSE: This phase II trial is studying how well radiofrequency ablation works in treating patients with stage I non-small cell lung cancer.

Primary Outcome Measures:
  • Overall survival at 2 years [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Overall time to local failure [ Designated as safety issue: No ]
  • Overall time to recurrence [ Designated as safety issue: No ]
  • Proportion of technical success [ Designated as safety issue: No ]
  • Adverse events [ Designated as safety issue: Yes ]

Estimated Enrollment: 55
Study Start Date: September 2006
Primary Completion Date: July 2010 (Final data collection date for primary outcome measure)
Detailed Description:



  • Determine the overall 2-year survival rate after radiofrequency ablation (RFA) of lung nodules in high-risk patients with stage IA non-small cell lung cancer.


  • Determine freedom from regional or distant recurrence in patients treated with this regimen.
  • Determine freedom from local recurrence in the ablated lobe at 2 years in these patients.
  • Determine the number of procedures deemed technical successes in patients treated with this regimen.
  • Determine procedure-specific morbidity and mortality.
  • Determine the utility of immediate (within 96 hours) post-RFA positron emission tomography (PET) in predicting overall survival and local control in these patients.
  • Determine the effect of RFA on short-term (3 months post-RFA) and long-term (24 months post-RFA) pulmonary function in these patients.

OUTLINE: This is a multicenter, pilot study.

A radiofrequency electrode is placed by CT guidance into the target tumor. Patients undergo radiofrequency ablation (RFA) directly to the tumor for up to 12 minutes to obtain an intratumoral temperature > 60°C. Patients may receive 3 RFA treatments (a total of 36 minutes) to obtain the target temperature. Patients undergo fludeoxyglucose F18 positron emission tomography within 24-96 hours after the final treatment.

After completion of study treatment, patients are followed every 3 months for 1 year and then every 6 months for 1 year.

PROJECTED ACCRUAL: A total of 55 patients will be accrued for this study within 20 months.
