预后营养指数 (PNI) 是乳腺癌预后的重要预测指标. 较高的PNI水平表明更好的预后,建议在个性化治疗策略中使用它.
科学领域:
- 在瘤学瘤学.
- 临床营养学 临床营养学
- 生物标志物 生物标志物
背景情况:
- 预后营养指数 (PNI) 反映了患者的营养和免疫状态.
- 建议PNI在乳腺癌预后中的作用,但由于相互矛盾的发现,需要澄清.
- PNI与瘤细胞清除和减少复发率有关.
研究的目的:
- 在乳腺癌患者中全面评估PNI的预后价值.
- 澄清PNI与乳腺癌生存结果之间的关联.
主要方法:
- 在PubMed,Embase,Cochrane图书馆和Web of Science数据库中进行系统的文献搜索 (截至2023年3月).
- 包括7项研究,包括2212名乳腺癌患者.
- 对整体存活率 (OS),无病存活率 (DFS) 和无进展存活率 (PFS) 的危险比率 (HR) 和95%信心区间 (CI) 的元分析.
主要成果:
- 高PNI是乳腺癌患者改善的OS和PFS的独立预测因子 (OS:HR=.38,95%CI .31∼.46;DFS:HR=.32,95%CI .19∼.51).
- 亚组分析显示,在≥300名患者的研究中,高PNI预测了更长的DFS (HR=.39,95%CI .28~.54).
- 在没有接受新辅助化疗的患者中,高PNI也预测了更长的DFS (HR=.51,95%CI .37∼.70).
结论:
- PNI与乳腺癌患者的预后有显著的相关性.
- 建议根据PNI水平进行个性化向治疗和长期监测.
- 在乳腺癌管理中,PNI作为一种有价值的预后生物标志物.
