PURPOSE: We investigated implanting computed tomography (CT)-guided (125)I 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 (125)I 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 5-56 months). Overall 2-year local control rate for existing lung lesions was Group A: 39.9 %; Group B: 12.5 % (P < 0.05). The 1-, 3-year, and median overall survival was 68.7 and 20.8 % at 17.4 months in Group A; and 45.1 and 18.7 % at 11.3 months in Group B, respectively (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 < 0.05). Group A showed no radiation-related pneumonia, esophagitis, bronchial fistulae, or life-threatening morbidity. CONCLUSION: CT-guided radioactive seed (125)I 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.
