摘要 目的探讨K-ras基因突变能否预测结直肠癌术后辅助化疗的预后。方法采用回顾性队列研究方法收集和分析临床病理资料,HRM法测定Ⅲ期结直肠癌K-ras基因突变,Kaplan-Meier和Cox比例风险模型评估K-ras基因突变对预后的影响。结果Ⅲ期结直肠癌K-ras基因突变发生率为28.9%,K-ras基因野生型与突变型的5年无瘤生存率(DFS)和总生存率(OS)分别为53%和51%(P=0.38)、56%和58%(P=0.56)。无论是单因素分析还是多因素分析均显示K-ras基因状态对Ⅲ期结直肠癌术后辅助化疗的DFS和OS均无明显影响(P>0.05)。结论 K-ras基因突变状态与Ⅲ期结直肠癌术后辅助化疗的预后无明显相关性。
