目的

探讨X射线损伤修复交叉互补基因1(XRCC1)单核苷酸多态性与晚期宫颈癌TP方案疗效的关系。

方法

收集2010年1月至2011年12月于本院化疗的晚期宫颈癌患者97例为研究对象,采用聚合酶链反应-限制性片段长度多态性技术(PCR-RFLP)检测其外周血DNA XRCC1 Codon 399位点多态性(本研究遵循的程序符合本院人体试验委员会制定的伦理学标准,得到该委员批准,并于受试者签署临床研究知情同意书)。采用紫杉醇+卡铂(TP)化疗方案,化疗3个疗程后评价其疗效,并分析化疗疗效与基因多态性的关系。

结果

本组97例患者中,疗效判定有效者为48例,无效为49例,总有效率为49.48%。携带XRCC1基因Codon 399 G/G基因型患者的化疗有效率为38.24%(13/34),G/A患者的化疗有效率为47.37%(18/38),A/A患者的化疗有效率为68.00%(17/25),G/G基因型和A/A基因型的化疗有效率比较,差异有统计学意义(P<0.05),其余两者间比较,差异无统计学意义(P>0.05)。3种不同的XRCC1 Codon 399单核苷酸多态型与晚期宫颈癌化疗疗效之间,存在正相关(r=0.9992,P<0.05)。

结论

XRCC1 Codon 399基因型可预测晚期宫颈癌TP方案化疗的疗效。

Objective

To study the correlation between single nucleotide polymorphism of X-ray cross complementing group 1(XRCC1) and chemotherapy sensitivity of the advanced cervical cancer patients with TP chemotherapy regimens (taxol+ carboplatin).

Methods

The XRCC1 polymorphism at 399 site was detected in 97 patients with advanced cervical cancer patients, who recruited into our hospital from January 2010 to December 2011, by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). They were treated with TP chemotherapy and evaluated before and after three periods of chemotherapy, and then the correlation of the sensitivity of chemotherapy with polymorphisms was analyzed. The study protocol was approved by the Ethical Review Board of Investigation in Human Being of Affiliated Yancheng Hospital of Southeast University Medical College. Informed consent was obtained from all participates' parents.

Results

The total effective rate was 49.48%(48/97). The effective rates of chemotherapy were 38.24%(13/34) in patients with the XRCC1 codon 399 G/G, 47.37%(18/38) in 399 G/A, and 68.00%(17/25) in 399 A/A. There had significant difference of effective rates between 399 G/G and 399 A/A (P<0.05).

Conclusions

The genotype of XRCC1 Codon 399 may be used in prediction of chemotherapy efficacy for advanced cervical cancer.
