摘要 目的:探讨晚期肺腺癌中TTF-1和TS的表达与培美曲塞化疗疗效的关系。方法:回顾性分析80例接受培美曲塞化疗的晚期肺腺癌患者的临床病理资料。免疫组织化学法检测肿瘤标本TTF-1和TS蛋白的表达,并对疗效进行分析。结果:TTF-1阳性表达率为71.25% (57/80),TS阳性表达率为22.50% (18/80)。TTF-1和TS在肺癌中的表达呈负相关性(r = ?0.356,P = 0.002)。化疗有效率(CR + PR)为46.25%,TTF-1(+)患者有效率(64.91%)显著高于TTF-1(?)患者(39.13%),差异有显著性(P <0.05)。TS(+)患者有效率(27.78%)显著低于TS(?)患者51.61%,差异有显著性(P <0.05)。联合检测显示:TTF-1(?)且TS(+)组有效率为28.57%,中位无疾病进展时间为3.9个月,1年生存率为28.6%,TTF-1(+)且TS(?)组有效率为81.13%,中位无疾病进展时间为7.4个月,1年生存率为69.8%,差异均有显著性(P <0.05)。结论: 联合检测TTF-1和TS的表达可作为培美曲塞化疗方案治疗晚期肺腺癌的疗效预测指标之一。
