Combination of cryosurgery and Iodine-125 seeds brachytherapy for lung cancer.

It has been proven that radioactive seeds such as Iodine-125 seeds implantation is a highly effective treatment for patients with localized cancer, such as lung cancer. It may increase the effectiveness of cryosurgery for lung cancer with the combination of Iodine-125 seed implantation into edge of the cryoablation zone. Percutaneous cryosurgery and Iodine-125 seed implantation are mutual complementation; both have been proved to be safe and effective modality for unresectable lung cancer, especially for centrally located lung cancer. Well-designed, randomized and control study both in the laboratory and in the clinical about this option are needed before the conclusive evidence submits.
