Abstract

放射治疗在肺癌治疗中占据重要地位。表皮生长因子受体(epidermal growth factor receptor, EGFR)突变是晚期非小细胞肺癌(non-small cell lung cancer, NSCLC)使用酪氨酸激酶抑制剂(tyrosine kinase inhibitor, TKI)治疗有效的预测因子。同时,EGFR突变型NSCLC对放射治疗敏感,这可能与突变型EGFR不能有效进行核转位而导致DNA损伤修复功能受损相关。初步研究显示EGFR酪氨酸激酶抑制剂在NSCLC放射治疗中具有一定的放疗增敏作用,但其在EGFR突变型NSCLC放疗中的疗效尚不确切。EGFR突变与NSCLC的放疗效应机制及生存预后的关系值得进一步研究。
