    Abstract:
    OBJECTIVES: To evaluate the feasibility, safety, and efficacy of computed tomography(CT)-guided percutaneous radiofrequency ablation (RFA) in medically inoperable older adults with clinical stage I non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: We retrospectively reviewed the records of medically inoperable older adults (≥70 years) with clinical stage I NSCLC who underwent percutaneous multi-tined electrode RFA at our institution between January 2014 and December 2018. We analyzed the patients' characteristics, therapy response, survival, as well as the procedure-related complications. RESULTS: Eighteen patients (10 men and 8 women) with a mean age of 75.9 (71-85) years were treated in during the study period. The median tumor size was 25 mm (range, 19-43 mm); 10 and 8 cases involved stage T1 and T2a disease, respectively. The median follow-up duration was 25 (11-45) months. RFA was technically successful for all 18 lesions, with no treatment-related mortality. The disease control rate was 83.3% (15/18 lesions). There were 6 cases of pneumothorax: one symptomatic case requiring thoracic drainage, and five requiring no treatment. Minor complications, including pulmonary infection, chest pain, fever, and cough, were treated within 4 days (range, 1-4 days). The progression-free survival rates were 83.3%, 64.9%, and 51.9% 1, 2, and 3 years, respectively. The corresponding overall survival rates were 92.2%, 81.5%, and 54.3%, respectively. CONCLUSIONS: CT-guided percutaneous RFA is safe and effective in medically inoperable patients with stage I NSCLC and could be an alternative therapeutic strategy, particularly in older adults with early-stage peripheral lung cancer.
