The clinic application of implantation iodine-125 seeds guided by CT for elderly non-small cell lung cancer

Abstract

Objective To evaluate the efficacy and safety of brachytherapy by percutaneous paracentesis implantation of iodine-125 seeds for elderly non-small cell lung cancer. Methods 18 patients with peripheral lung cancer were undergone brachytherapy by percutaneous paraeentesis implantation of iodine-125 seeds. The effect was evaluated by periodically chest CT. The complications were analyzed. Results 18 patients were observed one,two and six months after operation. CR,PR,SD were seen in 27.8% （3/18） ,66.7% （14/18） ,5.6% （1/18） respectively of the patients. Pneumothorax, hemoptysis were seen in 16.67% （3/18） ,95.37% （ 17/18 ）, no pleural cavity bleeding. Coneluslon Brachytherapy by percutaneous paraeentesis implantation of iodine-125 seeds for lung cancer was effecitve. The complications were easy to treat. The methods of implantation of iodine-125 seeds could fully play the advantages of CT,and reduce the damage to the body when raising the tumorous control rate.
