1、第35卷第9期河北医科大学学报Vo1.35No.92014年9月J0URNALOFHEBEIMEDICALUNIVERSITYSept.2014·论著·UGT1A1基因多态性与小细胞肺癌伊立替康化疗毒性和疗效的研究赵晓光,宋明霞,徐洁,王玉洁(河南省焦作市人民医院肿瘤内科,河南焦作454002)【摘要】目的探讨中国人小细胞肺癌患者尿苷二磷酸葡糖苷酸转移酶1A1(uridinediphosphateglucuronosyltransferase1A1,UGT1A1)基因多态性分布与伊立替康(ifinotecan,CPT一11)化疗毒性和疗效的关系。方法接受CPT一11
2、联合顺铂一线治疗的小细胞肺癌患者34例,外周血中提取DNA,PCR法扩增目的基因片段,直接测序法分析UGT1A128基因多态性,并与不良反应及近期疗效进行分析。结果34例患者中UGT1A128野生纯合型(TA6/6)最常见为26例(76.5%),其次为突变杂合型(TA6/7)6例(17.6%);突变纯合型(TA7/7)仅2例(5.9%),UGT1A128非野生型可增加患者发生Ⅲ度以上腹泻的风险(P<0.05)。结论中国人小细胞肺癌患者UGT1A128突变频率低,TA6/7和TA7/7基因型可增加应用CPT一11后III度以上腹泻的风险,但不影响疗效。【关键词】小细胞
