KRAS突变新型预后异质性评分系统的建立及在转移性结直肠癌患者中的临床意义
发布时间:2022-02-09 02:09
目的:建立新型预后评分系统以及探讨鼠类肉瘤病毒癌基因(Kisten rat sarcoma viral oncogene,KRAS)突变在转移性结直肠癌患者中的预后异质性。方法:通过回顾性分析的方法,收集自2017年8月1日至2019年4月30日河北医科大学第四医院入住我院均经组织病理学诊断为结直肠癌1700例患者的性别、年龄、分期、部位、脉管瘤栓及神经受侵、淋巴结转移、肿瘤大小、肿瘤浸润深度、转移部位、KRAS突变状态、无病生存期(Disease-free survival time,DFS)等临床特征,建立数据库,选择资料完整的52例KRAS突变患者,该类患者仅行KRAS检测,未行其它基因检测。应用SPSS21.0统计软件分析数据,筛选可能影响结直肠癌术后早期复发转移的高危因素,建立预后评分系统。将有无脉管瘤栓或神经受侵、分级程度、浸润深度、转移部位纳入简化评分系统:仅基于临床病理学协变量,不包括实验室值。从4个Cox模型获得的风险比(Hazard ratio,HR)用于推导预后分值:有脉管瘤栓或神经受侵者2.0分,分级程度为G3-G4为0.4分,侵透浆膜层者为0.3分,有肝或肺转...
