Abstract:
Objective To observe the efficiency and safety of brachytherapy by CT-guided percutaneous paracentesis implantationof iodine-125 seed for lung cancer in elder patients.Methods 46 elder patients with lung cancer(65~81 years)were undergonebrachytherapy by CT-guided percutanepus paracentesis implantation of iodine-125 seeds with implanting needle(18-gauge). The effect of treatment according to observe the changes of tumors in size was evaluated after operation 1,2,3 and 6 months,respectively. Results There were totally 57 lesions in 46 cases,7 cases were undergone two times of implantation,and 1 case was undergone three times of implantation,totally the puncture accounted for 76. The effective rate (CR+PR) of treatment after one ,two, three, and six months was 8.77%(5/57), 40.35%(23/57),89.47%(51/57) and 96.49%(55/57),respectively. 5 patients(6.58%) accompanied by pneumathorax.Conclusion Brachytherapy by CT-guided percutaneous paracentesis implantation of iodine-125 seed is a safe, reliable and effective treatment for lung cancer, especially for elder patients.
