Combination chemotherapy of gemcitabine and cisplatin by double way plus implantation of radioactive seed 125I in treating stage Ⅲ non-small cell lung cancer

Objective To assess the therapeutic effect of combination chemotherapy of gemcitabine and cisplatin by double way plus implantation of radioactive seed 125I implantation in treating stage Ⅲ non-small cell lung cancer. Methods Sixty cases with stage Ⅲ non-small cell lung cancer were randomly divided into two groups with random number table. In group A (in interventional treatment group, n = 30),the gemcitabine 1000 mg/m2 and one third of the cisplatin 100 mg/m2 was given using seldinger technique for transcatheter bronchial arterial infusion chemotherapy on day 1. Two-thirds of the cisplatin 100 mg/m2 was infused in veins on day 2 and 3. The gemcitabine 1000 mg/m2 was infused in veins on day 8, 21 days for a period. In group B (interventional - 125I groups), the method of combination chemotherapy of gemcitabine and cisplatin was the same as in Group A. After ten days of arterial perfusion, 125I seeds were implantated, 21 days for a period. All patients received at least 2 cycles. The imaging evaluation of patients after treatment standards included complete remission (CR), partial remission (PR), stable (SD),progressive disease (PD), effective rate (CR + PR)/30 and clinical benefit rate (CR + PR + SD)/30.Non-parametric rank sum test was used to compare short-term effect of the two groups treatment of two cycles.x2 test was used to compare year survival, Kaplan-Meier method was used to calculate median survival,log-rank test method was used to difference between the groups. Results In group A, there were 17 PR,9SD and 4 PD. The overall response rate was 56. 7% (17/30) and clinical beneficial rate was 86. 7% (26/30). In Group B, there were 2 CR, 21 PR, 7 SD. The overall response rate was 76.7% (23/30) and clinical beneficial rate was 100% (30/30). There was significant difference between the two groups (P =0. 036). In group A, the 1 year survival rate was 46. 7% (14/30) and the 2 year survival rate was 36. 7%(11/30), median survival time (MST) was 10 months . In group B, the 1 year survival rate was 76. 7%(23/30) and the 2 year survival rate was 63. 3% (19/30) , median survival time (MST) was 27 months.There was a significant difference between two group in 1 year survival rate (P = 0. 017), 2 year survival rate (P = 0. 039) and median survival time (P = 0. 006). Conclusion The treatment effects of Ⅲ stage non-small cell lung cancer by gemcitabine and cisplatin combination chemotherapy with double way plus radioactive seed 125I implantation was better than gemcitabine and cisplatin combination chemotherapy with double way.
