摘要
目的:探讨胞苷脱氨酶(cytidine deaminase,CDA)C435T基因多态性对吉西他滨治疗非小细胞肺癌(non-small cell lung cancer,NSCLC)远期疗效的影响。方法:收集2016年8月至2019年2月徐州医科大学附属医院接受吉西他滨-铂类治疗的非小细胞肺癌病例145例,记录年龄、性别、病理类型、临床分期(Ⅰ-ⅢA/ⅢB-Ⅳ)等基本临床特征,依据RECIST1.1标准评估,无病生存期(DFS)、无进展生存期(PFS)及总生存期(OS)为主要终点。检测CDA C435T基因型,病例分为野生型CC组与突变型CT/TT组。采用Kaplan-Meier法和log-rank检验分析CDA C435T与DFS、PFS及OS的关系,Cox模型分析预后影响因素。结果:Ⅰ-ⅢA期CC较CT/TT中位DFS延迟趋势不明显(16.8个月vs.35.7个月,P=0.294),中位OS无差异(54.3个月vs.81.9个月,P=0.256)。ⅢB-Ⅳ期CT/TT比CC中位PFS延长(10.4个月vs.5.0个月,P=0.009),中位OS无差异(16.2个月vs.24.3个月,P=0.087)。CC和CT/TT总体中位OS无差异(21.5个月vs.25.3个月,P=0.077)。Cox回归模型显示,CDA C435T是ⅢB-Ⅳ期PFS的独立影响因素(P=0.019)。结论:CDA C435T基因多态性对吉西他滨治疗ⅢB-Ⅳ期NSCLC的PFS具有预测性,CT/TT型明显延长。
AIM:To research the effects of cytidine deaminase(CDA)C435T polymorphism on the long-term effectiveness of gemcitabine in nonsmall cell lung cancer(NSCLC).METHODS:Enrolled 145 NSCLC patients received gemcitabine-platinum regiments at the Affiliated Hospital of Xuzhou Medical University from August 2016 to February 2019,characteristics recorded such as:age,gender,pathological type,clinical stage(I-IIIA/IIIB-IV)and so on.Followed-up and evaluated according to RECIST1.1,the disease-free survival(DFS),progression-free survival(PFS)and overall survival(OS)was study endpoint.Cases were categorized into wild-type CC and mutant CT/TT group.Kaplan-Meier method and log-rank test were utilized to analyze the relationship between CDA C435T and DFS/PFS/OS.A cox model was implemented to analyze the prognostic factors.RESULTS:In stage I-IIIA,median DFS of CT/TT compared with CC was not obvious(16.8 vs.35.7 months,P=0.294),same in median OS(54.3 vs.81.9 months,P=0.256).In stage IIIB-IV,the median PFS in CT/TT was longer than CC(10.4 vs.5.0 months,P=0.009),the median OS was undifferentiated(16.2 vs.24.3 months,P=0.087).No difference of overall median OS in CC and CT/TT genotypes was seen(21.5 months vs.25.3 months,P=0.077).Cox regression model showed CDA C435T polymorphism was an independent factor of PFS in stage IIIB-IV(P=0.019).CONCLUSION:CDA C435T polymorphism shows a function as a prediction influencing PFS of gemcitabine in IIIB-IV NSCLC,CT/TT genotype is significantly prolonged.
