摘要： 目的 探讨RAD23B基因rs10759225位点多态性与含铂类方案一线治疗中晚期非小细胞肺癌（non-small cell lung cancer，NSCLC）的疗效及血液学毒性的关系。方法 回顾性收集接受含铂类联合方案一线治疗的150例NSCLC患者的临床资料及外周血样本，采用改良多重高温连接酶检测反应技术对rs10759225进行基因分型，并分析其与患者疗效及血液学毒性的关系。结果 150例NSCLC患者的总有效率（ORR）为28.7%（43/150）。与携带G/G基因型患者比较，携带A等位基因型（G/A和A/A）患者接受含铂类方案治疗的ORR显著提高（OR校正=1.780，95%CI：1.110~2.884，P=0.042）。全组患者中位无进展生存期（mPFS）为5.6个月，各基因型患者的mPFS差异均无统计学意义（P>0.05）。以G/G基因型为参照，A/A基因型与患者化疗后发生Ⅲ/Ⅳ度白细胞减少的风险相关（OR校正=0.468，95%CI：0.204~0.711，P=0.008）；A等位基因型分别与患者发生Ⅲ/Ⅳ度中性粒细胞减少（OR校正=0.502，95%CI：0.155~0.887，P=0.022）和≥Ⅰ度血小板减少的风险有关（OR校正=0.494，95%CI：0.101~0.833，P=0.047）；而G/A基因型与患者发生Ⅱ/Ⅲ度贫血的风险有关（OR校正=0.504，95%CI：0.213~0.890，P=0.047）。结论 RAD23B基因rs10759225位点多态性与含铂类方案治疗NSCLC的疗效及血液学毒性有关，但与患者的预后无关。与携带G/G基因型患者比较，携带A等位基因型患者的疗效更好，但发生骨髓抑制的风险更高。

Abstract: Objective To investigate the relationship between the rs10759225 polymorphism of the RAD23B gene and clinical outcomes of platinum-based chemotherapy　as　first-line　treatment in patients with advanced non-small cell lung cancer（NSCLC）. Methods The clinical data and peripheral blood samples of 150 NSCLC patients receiving first-line treatment with platinum-based combination regimen were retrospectively analyzed.　The polymorphism of rs10759225 was genotyped by improved multiple ligase detection reaction（iMLDR） technology. Results The overall response rate（ORR） was 27.8%（43/150） of all group.Compared with G/G genotype carriers，A allele（included G/A genotype and A/A genotype） carriers had markedly higher response rate （ORadjusted =1.780，95%CI：1.110-2.884，P=0.042）.The median progression-free　survival（mPFS） of all patients was 5.6 months，and there was no significance of mPFS among difference genotype groups（P>0.05）.　Compared with G/G genotype （as a reference），A/A genotype increased the risk of grade Ⅲ/Ⅳ of leukopenia （ORadjusted=0.468，95%CI：0.204-0.711，P=0.008），and an allele was each associated with grade Ⅲ/Ⅳ of neutropenia （ORadjusted=0.502，95%CI：0.155-0.887，P=0.022） and grade ≥Ⅰ of thrombocytopenia（ORadjusted=0.494，95%CI：0.101-0.833，P=0.047），respectively.The risk of grade Ⅱ/Ⅲ anemia was significantly higher in patients with G/A genotype compared with G/G genotype carriers（OR校正=0.504，95%CI：0.213~0.890，P=0.047）.　Conclusions RAD23B gene rs10759225 polymorphism is associated with response rate and hematological toxicity of NSCLC patients treated with platinum-based chemotherapy，but there is no relationship between the polymorphism and the PFS of patients.Compared with G/G genotype carriers，A allele carriers may have better efficacy，and，as well as have a higher risk of myelosuppression.
