摘要
2009年12月至2011年12月中国医科大学附属第一医院对137名有明确病理诊断的非小细胞肺癌患者行胸部病灶三维适形放射治疗,放疗前及放疗20次后测量肿瘤大小,评价放疗肿瘤退缩率,外周血标本酚-氯仿法提取DNA,采用Taqman real-time PCR方法行单核苷酸多态性的基因分型。采用SPSS13.0软件对数据进行t检验和方差分析,p<0.05时认为有统计学差异。137例患者,平均年龄60.1±5.33岁,肿瘤平均退缩率0.3474±0.191,鳞癌87例,腺癌50例,男102例,女35例,Ⅰ期9例,Ⅱ期26例,Ⅲ期70例,Ⅳ期32例。实验结果显示,吸烟者(95例)放疗肿瘤退缩率明显高于非吸烟者,分别为0.3755±0.1775和0.2840±0.2068,t=2.643,p=0.009。LIG4rs1805388的CC、CT和TT基因型放疗肿瘤退缩率分别是0.3395±0.1802、0.342±0.2106和0.5038±0.1892,经LSD法比较发现,TT基因型放疗肿瘤退缩率明显高于CC基因型,p=0.041。HSPB1rs2868371 GG、CG和CC基因型放疗肿瘤退缩率分别是0.3454±0.1932、0.3487±0.1998和0.3487±0.1652,未发现3种基因型之间有统计学差异。吸烟和LIG4rs180538TT基因型患者放疗肿瘤退缩率明显高于其他患者。
