2018年5月,发表在《Ann Oncol》的一项由荷兰、意大利、德国和加拿大进行的系统评价和meta分析,考察了放化疗期间营养干预对患者营养和临床结局的影响。

背景:由于营养摄入降低和代谢的改变,于癌症患者营养不良对生活质量、治疗南山下和生存均产生不利影响。研究者考察了放化疗期间口服营养干预的相关证据。

设计:研究者对于旨在改善富含蛋白质和n-3多不饱和脂肪酸(PUFA)的摄入,从而调整癌症相关代谢改变的饮食咨询(DC)和高能量口服营养补充剂(ONS)的随机对照试验(RCT),开展了系统评价。对于营养干预相对应的体重(BW)进行meta分析,对DC和/或高能量ONS或富含高蛋白n-3 PUFA的ONS进行亚组分析。

结果:纳入11项研究。meta分析显示,放化疗期间干预对BW具有总获益(+1.31?kg,95% CI置信区间[CI],0.24~2.38,P?=?0.02;异质性Q=21.1,P=0.007)。亚组分析显示,对DC和高能量ONS没有影响(+0.80?kg,95% CI,?1.14~2.74,P?=?0.32;Q?=?10.5,P?=?0.03),很可能是由于依从性不佳,以及缺乏摄入目标而导致摄入降低。观察到与等热量控制相比,富含高蛋白n-3 PUFA具有显着影响(+1.89?kg,95% CI 0.51~3.27,P=0.02;Q=3.1,P=0.37)。高蛋白、富含n-3 PUFA的ONS的相关研究显示,较少的体重损失的减少(2项研究),以及一些领域生活质量的改善(3项研究)。总之,由于研究数量有限、异质性,不足以显示对于治疗毒性或生存的影响。

结论:该系统评价显示出化疗期间营养干预对BW的总体积极影响。亚组分析显示这种影响由富含高蛋白n-3 PUFA的ONS驱动,这表明靶向代谢改变的获益。DC和/或高能量ONS有效性较小,可能是由于累积热量不足。研究者强调需要对设计良好的RCT提供推荐建议,以确定营养干预对临床结局的影响,并作为综合性支持治疗方法的一部分,有特定的营养目标,提供正确的营养物质。
