2017年10月,发表在《Ann Oncol》的一项由意大利和瑞士科学家进行的随机、双盲、安慰剂-对照的多中心研究,考察了在接受高剂量顺铂的患者中,姜提取物能否有效预防化疗引起的恶心呕吐。

背景:姜治疗化疗引发的恶心呕吐(CINV)的作用已被证实,但设计的不完全、人群的异质性、小样本和测试产品质量较差限制了结论普适化的可能性。

患者和方法:研究人员开展了一项随机、双盲、安慰剂-对照的多中心研究,患者计划接受≥2个疗程的高剂量(>50 mg/m2)顺铂的化疗。患者接受姜提取物160 mg/日(生物活性成分的标准剂量)或安慰剂并联合标准止吐预防治疗CINV,应用时间从顺铂给药当日开始。通过每日视觉模拟量表和呕吐功能性生活指数的调查问卷评估CINV。主要目的是预防延迟恶心;次要终点包括周期内部的恶心和恶心预期的症状。

结果:总体上,121名患者接受姜提取物,123名患者接受安慰剂。肺癌(49%)和头颈部肿瘤(HNC,35%)是最具代表性的肿瘤。有关安全性或依从性的报道无差异。两组在第1和第2周期的延迟性、周期性、预期性恶心发生率没有差异。对女性(P=0.048)和头颈部肿瘤患者(P=0.038),姜提取物在呕吐功能性生活指数的差异(第6日~第1日)优于安慰剂。

结论:在高剂量顺铂治疗的患者中,每日添加姜提取物,虽然是安全的,但不会对CINV产生保护作用。在特定的恶心风险(女性;HNC)亚组中观察到有利的作用,值得特殊考察。
