Br J Cancer:前列腺癌组织代谢物中精胺浓度和tChoCre/Spm比值具有术前风险评估价值

2017-10-23 MedSci MedSci原创

前列腺切除标本中精胺浓度和tChoCre/Spm比值是复发的独立预后标志物。

背景:前列腺癌患者高危复发风险的健康生物标志物的鉴别对于癌症护理具有很大的作用。这项研究调查了HR-MAS MRS可检测到的组织代谢物是否与根治性前列腺切除术后的复发相关。

方法:研究人员进行了回顾性离体研究,使用HR-MAS MRS对2002年至2010年期间收集的来自三个不同挪威队列的110例根治性前列腺切除患者的组织样本进行检测。在分析时,有50例患者出现前列腺癌复发。使用Cox比例风险回归模型,Kaplan-Meier生存分析和一致指数(C-index)评估代谢物,临床病理变量和无复发生存之间的关联。

结果:肿瘤内高精胺和柠檬酸盐浓度与无复发生存时间延长相关,而总胆碱+肌酸/精胺(tChoCre/Spm)和总胆碱+肌酸/柠檬酸盐(tChoCre/Cit)比率升高与复发时间较短有关。调整临床相关危险因素后,精胺浓度和tChoCre/Spm与多因素Cox比例风险模型复发率独立相关(C指数:0.769;HR:0.72;P = 0.016和C指数:0.765;HR:1.43;P = 0.014)。

结论:前列腺切除标本中精胺浓度和tChoCre/Spm比值是复发的独立预后标志物。这些代谢物可以在体内进行非侵入性测量,因此对于建立术前风险评估标准图具有预测价值。
