RESUMEN

Objective To investigate the clinical efficacy of CT-guided 125I seeds implantation combined with gemcitabine + cis-platinum (GP) in the treatment of unresectable non-small cell lung cancer (NSCLC).Methods From January 2013 to January 2017,62 patients with unresectable Ⅱ b-Ⅲb NSCLC were randomly divided into 2 groups.In the study group,32 patients (17 males,15 females,age (62.7± 8.9) years) underwent 125I seeds implantation combined with 4 courses of GP chemotherapy,and 30 patients (18 males,12 females,age (61.9±7.0) years) in the control group underwent concurrent radiotherapy combined with 4 courses of GP chemotherapy.The short-term effects at 3 and 6 months after treatment were compared between 2 groups,as well as the survival time.Log-rank test was used to analyze the data.Results The effective rates at 3 and 6 months after treatment in the study group and control group were statistically significant (90.62% (29/32) vs 70.00% (21/30),96.88% (31/32) vs 66.67% (20/30);x2 values:3.00 and 7.22,both P<0.05).The median survival time of the study group and control group were 17 and 15 months (x2 =2.194,P>0.05).The 1-year survival rates of 2 groups were 87.50% (28/32) and 76.67% (23/30),respectively (x2=1.24,P>0.05),and the 2-year survival rates were 40.62% (13/32)and 20.00%(6/30),respectively (x2=4.00,P<0.05).Conclusions 125I seeds implantation combined with GP chemotherapy is a significant treatment for unresectable NSCLC.The short-term efficacy is better than concurrent radiotherapy combined with GP regimen.

RESUMEN

Objective To assess the therapeutic effect of radioactive seed 125I brachytherapy combined with GP chemotherapy regimen (gemcitabine 1000 mg/m2, cisplatin 75 mg/m2) for inoperabale stage Ⅲ non-small cell lung cancer (NSCLC). Methods Thirty-nine documented inoperable stage Ⅲ NSCLC patients, enrolled between January 2005 and June 2008 for the study group, were treated with the combination of 125I brachytherapy and GP regimen. The brachytherapy methods were conducted according to TPS and each patient was treated under those patients were treated with standard GP regimen. Chest CT scans were performed every three months post-procedurally, until disease progression or recurrence. The follow-up time was up to twenty four months after treatment. In the control group, equal amount of Ⅲ stage NSCLC patients were treated with standard GP regimen alone. Chi-square test and survival analysis with Kaplan-Meier and Log-rank were used to compare the differences of recent (3 months after therapy)efficiency, survival rate, survival time between two groups. Results The re-cent effective rates of the study group (71.8%, 28/39) and control group (61.5%, 24/39) were not statistical different (χ2=0.93, P>0.05), yet the tumor CR rates in two groups showed significant disparity (χ2=4.48, P0.05). However, singificant differences (χ2=4.07, 4.63,both P<0.05) were found in 2-year survival rate and median survival time, with 41.0% (16/39) vs 23.1% (9/39) and 18.9±2.7 months vs 14.2±0.7 months. Conclusions 125I brachytherapy combined with GP regimen chemotherapy could be an effective treatment method and could improve the tumor CR rate and survival rate for patients with inoperable stage Ⅲ NSCLC.
