Purpose We investigated implanting computed tomography (CT)-guided 125I seed to treat locally advanced non-small-cell lung cancer (NSCLC) after chemotherapy failure. Methods From January 2005 to July 2010, we recruited 69 patients with locally advanced NSCLC who had each had first-line chemotherapy four to six times but had progressive disease; 34 received 125I seed implantation with second-line chemotherapy (Group A) and 35 received second-line chemotherapy only (Group B). Results Mean follow-up was 32?months (range 5-6?months). Overall 2-year local control rate for existing lung lesions was Group A: 39.9?%; Group B: 12.5?% (P?P?>?0.05). Local 3-, 24-month, and median progression-free survival was Group A: 100 and 79.1?% at 11?months; Group B: 76.5 and 18.7?% at 7.3?months, respectively. The groups did not significantly differ in treatment toxicity. Chest pain remission was Group A: 82.1?% (23/28); Group B: 30.8?% (8/26) (P? Conclusion CT-guided radioactive seed 125I implantation procedure is safe and well tolerated in treating locally advanced NSCLC, with few complications. It has good local control rate and can relieve symptoms without increasing side effects.
