Lancet oncol:三氟尿苷/替匹拉齐可明显提高晚期胃癌患者的总体存活期

2018-10-27 MedSci MedSci原创

在日本进行的一项针对晚期胃癌患者的2期研究中,三氟尿苷/替匹拉齐表现出活性而且耐受性良好。三氟尿苷/替匹拉齐用于全球人群是否还具有相应的疗效?研究人员现对此进行研究。TAGS是一项在17个国家的110个学术医院进行的随机的、双盲、安慰剂为对照的3期试验,招募年满18岁的组织学确诊的不可手术切除的转移性胃腺癌(包括胃食管连接处腺癌)患者,并要求既往至少采用过两种化疗,且经历过放疗病程进展。患者按2:

在日本进行的一项针对晚期癌患者的2期研究中,三氟尿苷/替匹拉齐表现出活性而且耐受性良好。三氟尿苷/替匹拉齐用于全球人群是否还具有相应的疗效?研究人员现对此进行研究。

TAGS是一项在17个国家的110个学术医院进行的随机的、双盲、安慰剂为对照的3期试验,招募年满18岁的组织学确诊的不可手术切除的转移性腺癌(包括胃食管连接处腺癌)患者,并要求既往至少采用过两种化疗,且经历过放疗病程进展。患者按2:1被随机分至三氟尿苷/替匹拉齐组(35mg/m2 口服 2次/日,第1-5天和8-12天,28天一疗程)或安慰剂组,均额外予以最好的支持护理。主要结点是总体存活期。

2016年2月24日-2018年1月5日,共招募了507位患者,337位分至三氟尿苷/替匹拉齐组、170位分至安慰剂组。三氟尿苷/替匹拉齐组和安慰剂组的中位总体存活期为5.7个月(95% CI 4.8-6.2)和3.6个月(3.1-4.1;风险比0.69[95% CI 0.56-0.85],单边p=0.00029,双边p=0.00058)。三氟尿苷/替匹拉齐组和安慰剂组任何原因的3级以上副反应发生率分别为80%(267位)和58%(97位)。三氟尿苷/替匹拉齐组最常见的3级及以上副反应是中性粒细胞减少(34%)和贫血(19%);安慰剂组最常见的3级及以上副反应是腹痛(9%)和身体健康综合恶化(9%)。三氟尿苷/替匹拉齐组和安慰剂组的严重副反应发生率分别是43%和42%。两组各一例治疗相关的死亡(三氟尿苷/替匹拉齐组和安慰剂组死于心脏骤停、安慰剂组死于中毒性肝炎)。

相比安慰剂,三氟尿苷/替匹拉齐可显著提高晚期胃癌患者的总体存活期,而且耐受性较好。三氟尿苷/替匹拉齐或可作为该患者人群的新的治疗选择。
