Ann Oncol:肌酸能否缓解癌症厌食/减重综合征

2017-05-09 MedSci MedSci原创

本项研究为多项试点研究,包括一项在结肠直肠癌患者中的研究,表明肌酸,一种氨基酸衍生物,可以增强肌肉,提高强度,从而缓解癌症厌食症/体重减轻综合征。

本项研究为多项试点研究,包括一项在结肠直肠癌患者中的研究,表明肌酸,一种氨基酸衍生物,可以增强肌肉,提高强度,从而缓解癌症厌食症/体重减轻综合征。

在这项随机,双盲,安慰剂对照试验中,不可治愈的患有这种综合征的患者观察组服用肌酸(每天20克负荷×5天,然后口服2克),对照组使用相同量的的安慰剂。对患者每周称重一次,连续观察一个月,然后每月称重一次。对患者的食欲和生活质量(有效问卷),拳头握力,身体成分(生物电阻抗)和不良事件也在一个月内进行了评估。主要终点是在第一个月内增加基线的10%体重或增加更多的体重。

在263名可评估患者(134名接受肌酸和129名安慰剂)的联合队列中,只有3人在第一个月内增加了超过基线10%的体重:其中2人是使用肌酸的实验组,另一人是安慰剂对照组(p = 1.00)。有关食欲,生活质量和日常生活活动的问卷数据显示,组间差异并无统计学意义。类似地,在握拳强度或身体成分方面也并没有观察到组之间的统计学显着性差异。不良事件的发生率和严重程度在两组之间相比,在肌酸组和安慰剂组中观察到中位生存期分别为230天和239天(p = 0.70)。

由于研究数据表明两组之间差异没有统计学差异,因此本试验中设定的肌酸使用对癌症厌食症/体重减轻综合征无影响。
