['Objecive: To investigate the clinical safety and efficacy of CT-guided 125iodine (125I) seed implantation combined with percutaneous intra-tumor injection of chemotherapy emulsion of lobaplatin and lipiodol in treating patients with advanced lung cancer.', 'Patients with advanced lung cancer and treated with spiral CT-guided 125I seed implantation combined with percutaneous intra-tumor injection of chemotherapy emulsion of lobaplatin and lipiodol were recruited.', 'Of the 36 patients, there were 40 nidi in total. The contrast-enhanced CT evaluation was conducted 60 d after treatment. Response evaluation suggested that 4 patients achieved complete remission (CR), 24 partial remission (PR), 4 stable disease (SD) and 4 progression disease (PD), with a total response rate of 77.8% (28/36).'] Are radioactive seed implantation and lobaplatin chemotherapy safe and effective in treating patients with advanced lung cancer?
