Abstract:
ObjectiveTo analyze therapeutic efficiency of 125 iodine brachytherapy seeds implantation guided by flexible fiber-optic bronchoscopy(FFB)image in terminal central non-small cell lung carcinoma (NSCLC).MethodsUnder therapy planning system (TPS) and guided by flexible fiber-optic bronchoscopy image,125 iodine seeds were implanted in 66 Confirmed terrainal cases with NSCLC and its posology Was validated and rechecked regularly.Remlts Complete remission (CR) was observed in 15 cases and partial remission (PR) in 36 cases during the first-year follow-up,with an overall efficiency rate (CR+PR) of 77.3 percent and one-year survival of 80.3 percent.Complete remission (CR) was observed in seven cases,partial remission (PR) in 22 cases,stable condition (SC) in three cases.and no progression was found during the second-year follow-up,respectively,with an overall efficiency rate (CR+PR) of 90.6 percent and two-year survival of 43.8 percent No radioactive damage were observed in the early and late stages of therapy.ConclusionsTherapy with radioactive 125 iodine seeds implantation guided by flexible fiber-optic bronchoscopy image could relieve airway obstruction effectively in terminal lung cancer and control progression of bronchiogenic carcinoma.
