Published data showed inconsistent results about associations of extensively studied polymorphisms with platinum-based chemotherapy response. Our study aimed to provide reliable conclusions of these associations by detecting genotypes of the SNPs in a larger sample size and summarizing a comprehensive pooled analysis. 13 SNPs in 8 genes were genotyped in 1024 NSCLC patients by SequenomMassARRAY. 39 published studies and our study were included in meta-analysis. Patients with GA or GG genotypes of XRCC1 G1196 had better response than AA genotype carriers (Genotyping study: OR = 0.72, 95%CI: 0.53-0.96, P = 0.028; Meta-analysis: OR = 0.74, 95%CI: 0.62-0.89, P = 0.001). Patients carrying CT or TT genotypes of XRCC1 C580T could be more sensitive to platinum-based chemotherapy compared to patients with CC genotype (OR = 0.54, 95%CI: 0.37-0.80, P = 0.002). CC genotype of XRCC3 C18067T carriers showed more resistance to platinum-based chemotherapy when compared to those with CT or TT genotypes (OR = 0.69, 95%CI: 0.52-0.91, P = 0.009). Our study indicated that XRCC1 G1196A/ C580T and XRCC3 C18067T should be paid attention for personalized platinum-based chemotherapy in NSCLC patients.
已发表的数据显示，关于广泛研究的多态性与铂类化疗反应之间的关联，结果并不一致。我们的研究旨在通过检测更大样本量的单核苷酸多态性（SNP）基因型并汇总全面的合并分析，来提供这些关联的可靠结论。通过Sequenom MassARRAY对1024例非小细胞肺癌（NSCLC）患者的8个基因中的13个SNP进行了基因分型。39项已发表的研究和我们的研究被纳入荟萃分析。携带XRCC1 G1196的GA或GG基因型的患者比AA基因型携带者对化疗的反应更好（基因分型研究：比值比[OR]=0.72，95%置信区间[CI]：0.53-0.96，P=0.028；荟萃分析：OR=0.74，95%CI：0.62-0.89，P=0.001）。与携带CC基因型的患者相比，携带XRCC1 C580T的CT或TT基因型的患者可能对铂类化疗更敏感（OR=0.54，95%CI：0.37-0.80，P=0.002）。与携带CT或TT基因型的患者相比，XRCC3 C18067T携带者的CC基因型对铂类化疗表现出更大的耐药性（OR=0.69，95%CI：0.52-0.91，P=0.009）。我们的研究表明，在NSCLC患者的铂类化疗个体化中，应关注XRCC1 G1196A/C580T和XRCC3 C18067T。
