Onco Targets Ther:靶向Fn或可用于结直肠癌的预防及治疗

2017-10-31 MedSci MedSci原创

结直肠癌(CRC)是一种常见的消化系统恶性肿瘤,近期研究发现CRC的发生与肠道菌群变化密切相关。已知具核梭杆菌(Fn)为大肠癌的致病菌;然而,Fn与患者预后之间的关系研究尚少,且在晚期患者的研究也较少。因此,在这项研究中,研究人员在280个III期/ IV期CRC患者的回顾性队列中研究Fn的水平和对患者的预后意义。结果发现,肿瘤组织中Fn的水平异常高,与肿瘤浸润、淋巴结转移及远处转移有关。此外,研

结直肠癌(CRC)是一种常见的消化系统恶性肿瘤,近期研究发现CRC的发生与肠道菌群变化密切相关。已知具核梭杆菌(Fn)为大肠癌的致病菌;然而,Fn与患者预后之间的关系研究尚少,且在晚期患者的研究也较少。因此,在这项研究中,研究人员在280个III期/ IV期CRC患者的回顾性队列中研究Fn的水平和对患者的预后意义。

结果发现,肿瘤组织中Fn的水平异常高,与肿瘤浸润、淋巴结转移及远处转移有关。此外,研究还确定Fn为癌症特异性生存(CSS)和无病生存(DFS)的独立不良预后因子。亚组分析表明,IIIB/C和IV患者中Fn的水平可将CSS和DFS分层,但是对于IIIA期患者却不能。此外,III/IV期患者中低Fn水平的患者较高Fn水平的患者对辅助化疗的反应更好。

最后,研究人员分析了结直肠癌组中上皮间充质转化(EMT)标志物(E-cadherin和N-cadherin)和癌症干细胞(CSC)标志物(Nanog,Oct-4、Sox-2)的表达及临床意义。结果表明,这些患者中N-cadherin、Nanog、Oct-4、Sox-2是不良的预后因素,而E-cadherin则是预后较好的预测因子。更重要的是,E-cadherin、N-cadherin和Nanog的表达与肿瘤组织中Fn的水平显著相关,提示CRC的进展中Fn在EMT-CSC串扰的潜在作用。

总之,这些发现提示Fn是Ⅲ/Ⅳ期患者临床治疗的一种新的预测生物标志物,靶向Fn或是预防结直肠癌转移和化疗耐药的有效辅助手段。
