Abstract:
Objective To evaluate the clinical effects of CT-guided 125I radioactive seed implantation in treatment of stage Ⅲ non-small cell lung cancer ( NSCLC ) and the influential factors of prognosis.Methods 247 patients of stage Ⅲa/Ⅲb NSCLC underwent CT-guided 125I radioactive seed implantation.The clinical effects and the factors affecting prognosis were analyzed by univariate and multivariate analyses.Results The 1-,3-,and 5- year overall survival rates were 82.8%,23.8%,and 11.5 %,respectively.The median survival time was 24.8 months,and the local control rate was 92.2 %,63.8%,and 25.7%,respectively.The 5- year overall survival rate was 14.7%,and the median survival time was 29.7 months of the stage Ⅲ,patients.And the 5- year overall survival rate was 11.2%,and the median survival time was 24.0 months at the stage Ⅲb.Univariate analysis showed that age,course of disease,hemoglobin before treatment,clinical stage,maximum diameter of tumor,prescribed dose (PD),post-operational mean dose,post-operational dose covering 100% volume (D100),remedial model were the main prognostic factors; however,multivariate analysis revealed that hemoglobin ≥ 120 g/L before treatment,post-operational dose covering 100% volume (D100) and maximum diameter of tumor were the independent risk factors for predicting the survival.Aerothorax was observed in 37 patients with an incidence rate of 14.9%,and hemothorax was observed in 22 patients with an incidence rate of 9%.Conclusions 125I radioactive seed implantation therapy is effective in the treatment of stage Ⅲ NSCLC.Hemoglobin level before treatment,post-operational dose covering 100% volume (D100 ),and maximum diameter of tumor are the main prognostic factors for the NSCLC patients treated with radiotherapy for NSCLC.
