Objective:This study aimed to observe the clinical efficacy of implanting radioactive 125I seeds to treat non-small cell lung cancer (NSCLC) on the basis of the recent changes in serum tumor markers (including CEA, CA125, SCC-Ag, and CYFRA21-1). Methods:We selected 72 patients who were pathologically confirmed with NSCLC and received CT-guided percutaneous implantation of radioactive 125I seeds from January 2009 to June 2012. The concentration of the serum tumor markers was detected 3 d before implan-tation and 1, 2, 3, and 6 months after implantation. Result:All of the operations were successfully completed. One month after implan-tation, a significant change was observed in the concentration of serum tumor markers (CEA, CA125, SCC-Ag, and CYFRA21-1) com-pared with their preoperative levels (P<0.01). No significant difference was observed between the different time points after implanta-tion. Conclusion:The treatment of NSCLC by implanting radioactive 125I seeds can effectively reduce the level of tumor markers. A sig-nificant difference was observed in the level of tumor markers between patients with different efficacy classifications.

Objective:To evaluate the curative effect of computed tomography (CT)-guided percutaneous implantation of 125I radioactive seeds on inoperable early-stage non-small cell lung cancer (NSCLC). Methods:From January 2003 to December 2012, we selected 48 patients who had pathologically confirmed early-stage NSCLC (stageⅠ, 18 cases;stageⅡ, 30 cases with N0). We treated the nidus by CT-guided percutaneous implantation of 125I radioactive seeds. Six months after implantation, the chest CT-scan was reviewed, and the effect of the treatment was evaluated according to the international standards. Final follow-up was performed in December 2013. Results:All operations were successfully completed. The target tumor matched peripheral doses (MPDs) were 215.8±14.3 Gy (D100), 106.8±11.6 Gy (D90), and 148.6± 17.3 Gy (D90>MPD). Six months after implantation, chest CT was reviewed, and treatment effects were evaluated. The percentages of stage I patients achieving complete relief (CR), partial relief (PR), stable disease (SD), and progressive disease (PD) were 27.8%(5 cases), 72.2%(13 cases), 0%, and 0%, respectively. Among stageⅡpatients, CR, PR, SD, and PD percentages were 0%(3 cases), 73.3%(22 cases), 13.3%(4 cases), and 3.3%(1 case), respectively. The effective rate was 89.6%. The 1-year local control rate was 85%. Until December 2013, the 1-, 2-, and 5-year cumulative survival rates up to the end of the interval were 95.8%(46/48), 81.3%(39/48), and 56.3%(27/48), respectively. Conclusion:CT-guided percutaneous implantation of 125I radioactive seeds is an effective micro-invasive method for treating inoperable early-stage NSCLC.

Objective To explore influential factors of local therapeutic effect in CT guided brachytherapy of 125I seeds for non-small-cell lung carcinoma (NSCLC).Methods Totally 141 primary NSCLC patients diagnosed by bronchoscope or puncture biopsy were treated with CT guided 125I seeds implantation treatment from 2003 January to 2005 January.Among them,26 patients were treated with seeds implantation only and remaining 115 combined with chemical therapy.Preplans were performed by using treatment planning system before the implantation.We took the implantation with the prescription dose of 80-110 Gy,1 seed per 1 cm3,under the guide of computed tomography.Six months after implantation treatment,CT graphs were taken to evaluate the therapeutic effect.Results All the patients were survival until 6 months after implantation,and 37 were complete remission,93 were partial remissions.The effective rate was 92.2％.Among all the observed factors,pathologic type (F =5.162,P =0.023),dose of cover 100％ tumor(D100) (F =100.713,P =0.000) and treatment methods (F =16.205,P =0.000) were the independent influent factors (P ＜ 0.05).Among these,D100 was the most important factor (P =0.000).Single factor analysis indicated that pathologic type (x2 =7.313,P =0.007),D100 (x2 =71.6,P =0.000)and treatment methods (x2 =20.5,P =0.000) were significant influent factors.Of all 141 cases,24 had complications during or after implantation treatment,while no severe complications were reported.There was no significant correlation between complication and local therapeutic effect (P ＞ 0.05).Conclusion CT guided implantation of 125I seeds for lung cancer has good clinical effects and few complications.D100 is the most important factor to influence the local therapeutic effect.Implantation treatment combined with chemotherapy is an ideal measure for NSCLC treatment.

Objective To evaluate the effect of CT guided permanent 125I seeds implant brachytherapy on early non-small cell lung cancer (NSCLC) that is not suitable for operation.Methods 18 patients with early stage of NSCLC (stage Ⅰ and Ⅱ) were treated with CT guided permanent seeds 125I implantation from December 2002 to December 2006.The prescribed dose (PD)was 110 Gy,the median activity of 125I seed source was 0.7 mCi.The chest CT detection was performed at 1,2,6 months and 1 year after treatment.The tumor size and the clinical effect were compared before and after treatment.Results The minimum PD in target tumor was (107.7±5.3)Gy,D90 was (113±3.7) Gy,and D9o was more than mPD.The chest CT showed that complete relief (CR) was achieved in 7 patients (38.9％),partial relief (PR) was in 9 patients (50％),stable disease (SD) was in 2 patients (11.1％),no progress disease (PD) was found.The effective rate (CR rate + PR rate) was 92.9％ (16 cases),and local control rate was 88.9％ (16 cases) within one year.During the follow-up to December 2011,the 1,3 and 5 years cumulatively survival rate was 94.4 ％ (17 cases),72.2％ (13 cases),66.7％ (12 cases),56.8％ (10 cases) respectively.Median survival time was 58 months.Conclusions CT-guided permanent 125I seeds implant brachtherapy is effective in the treatment of early non-small cell lung cancer that is not suitable for operation.

Objective To observe the pulmonary protective effect of large and small doses of mucosolvan in elderly patients with lung cancer undergoing radioactive seed implantation.Methods 93 patients with non-small cell lung cancer undergoing radioactive seed implantation guided by CT were selected and randomly divided into 3 groups:the high-dose group,the low-dose group and control group (n-31,each).All patients received the mucosolvan treatment with routine immunization and nutrition support after implantation.Patients was given mucosolvan 990 mg/d and 300 mg/d by continuous intravenous pumping in high-dose and small-dose groups respectively.Patients in the control group was given saline.The incidence of pneumothorax and plasma levels of C reactive protein (CRP),tumor necrosis factor alpha (TNF alpha),neutrophils (ANC) were compared between the three groups at 1 d,3 d and 5 d after implantation.Results There was no statistically significant difference in plasm levels of CRP,TNF alpha and ANC between the three groups at 1 d and 3 d after implantation (all P＞0.05).Plasma levels of CRP,TNF alpha and ANC were lower in highdose group than in low-dose group and control group at 5 d after implantation (F=3.596,3.555,3.406,respectively,all P＜0.05).The incidence of pneumothorax was lower in high dose group than in control group (x2 =4.31,P ＜ 0.05).Conclusions Perioperative application of high-dose mucosolvan can relieve lung inflammatory reaction rapidly and reduce the incidence of pneumothorax in elderly lung cancer patients undergoing radioactive seed implantation.

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.
