Abstract：Objective To evaluate the clinical curative effect in treating primary lung cancer and metastatic lung cancer with microwave ablation.Methods The data of 69 cases with primary or recurrent non-small-cell lung cancer and metastatic lung cancer patients from January 2005 to January 2008 in our department were retrospectively analyzed.The survival rates and mortality rates within three years after operation were compared among different sizes of tumor.Results There were totally 26 patients with complications,including 13 cases with pneumothorax,5 cases with hemoptysis,2 cases with hemothorax,3 cases with pulmonitis,2 cases with temporary pain and 2 cases with low fever.No needle track implantation was found and no patients died within postoperatively 30 days.There were significant differences of tumors more than 4 cm and less than 4 cm in 3-year follow-ups.1,2,and 3-year overall survival rates of patients with non-small cell lung cancer patients and lung metastases were 77.1％ (37/48),43.7％ (21/48),22.9％ ( 11/48 ),and 52.4％ ( 11/21 ),28.6％ (6/21),14.3％ ( 3/21 ) ; cancer-free survival rates were 72.9％ ( 35/48 ),35.4％ (17/48),12.5％ (6/48) and 47.6％ ( 10/21 ),19.0％ (4/21),9.5％ ( 2/21 )respectively.The overall survival rates and cancer-free survival rates were significantly different between non-small cell lung cancer and lung metastases.Conclusion Microwave ablation of lung tumors is a safe and effective method to prolong the survival time of the patients with primary lung cancer and metastatic lung cancer and can improve patients' survival rates.
