Abstract

肺癌是最常见和死亡率最高的恶性肿瘤之一,75%-80%为非小细胞肺癌(non-small cell lung cancer, NSCLC)。且绝大部分患者就诊时已处晚期,失去了根治性手术或放疗的机会,化疗是主要的治疗手段。但由于肿瘤生物学行为的多样性和对化疗药物的耐药等,使得晚期NSCLC的化疗不容乐观。近年来,分子标志物的个体化化疗在晚期NSCLC的应用,使得这些患者生存期有所延长,生活质量有所提高。针对晚期NSCLC,根据分子标志物选择合适的药物,达到个体化化疗是临床中所要面对和解决的问题。本文就核苷酸还原酶M1(ribonucleotide reductase subunit 1, RRM1)在晚期NSCLC治疗和预后中的作用做一简要综述。由RRM1指导的个体化化疗并不能作为晚期NSCLC的常规决策,还需进一步研究。
