Radioactive Iodine-125 seed brachytherapy is a conventional treatment in Peking University Third Hospital. Radioactive Iodine-125 seed brachytherapy is the implantation of Iodine-125 seed into tumors.The radioactive Iodine-125 seed can release low dose of irradiation persistently which kills tumors cell and causes less damage to normal tissue at the same time. This study collects the data of patients with early stage (stage I-II, N0) non-small cell lung cancer who underwent CT-guided radioactive Iodine-125 seed implantation from 2010 to 2018. The investigators evaluate the dose that covers 90% target volume(D90) and other parameters after the implantation. The efficacy and adverse effects were observed. Local control(LC) time and overall survival(OS) time are evaluated.
