title: [Efficacy for artery chemoembolization combined with radiofrequency ablation in the treatment of advanced non-small cell lung cancer].
abstract: OBJECTIVE
  To investigate efficacy and safety of artery chemoembolization combined with radiofrequency ablation for advanced non-small cell lung cancer.
  
  
  METHODS
  A total of 138 cases of Sichuan Cancer Hospital of patients with advanced non-small cell lung cancer were retrospectively analyzed from January 2011 to November 2014.All cases were divided into three groups, 61 cases were treated by artery chemoembolization (ACB group), 43 cases were treated by artery chemoembolization combined with radiofrequency ablation (Joint group), 34 cases were treated by radiofrequency ablation (RFA group). Recent efficiency, overall survival time, adverse reactions and complications of three groups were analyzed. The risk factors related to survival time of 138 patients were analyzed.
  
  
  RESULTS
  The recent efficiency of ACB group, Joint group and RFA group were 73.8%(45/61), 93.0%(40/43), 85.3%(29/34), respectively, and the difference was statistically significant (χ(2)=18.499, P=0.005). 1, 2, 3-year survival rates of Joint group were 90.7%(39/43), 58.1%(25/43), 20.9%(9/43), respectively that were better than ACB group(57.4%(35/61), 24.6%(15/61), 11.5%(7/61)) and RFA group(58.8%(20/34), 32.4%(11/34), 11.8%(4/34)), (χ(2) value were respectively 8.242 and 4.934, P values were 0.004 and 0.026). Chemotherapy side effects and complications of ablation were of no significant difference (P>0.05). Chemotherapy side effects and complications of ablation were of no significant difference (P>0.05). The number of tumors, tumor size, TNM staging, eastern cooperative oncology group (ECOG) score were independent risk factors which impact on survival time for non-small cell lung cancer. The artery chemoembolization combined with radiofrequency ablation treatment can improve survival time of patients with advanced non-small cell lung cancer.
  
  
  CONCLUSIONS
  Artery chemoembolization combined with radiofrequency ablation is a safe, effective, minimally-invasive treatment for advanced non-small cell lung cancer.
