CLIN CANCER RES:CAR T细胞治疗EGFR阳性晚期胆道癌患者

2018-03-21 MedSci MedSci原创

胆道癌在东亚尤其是中国较为常见。诊断为晚期胆道癌的患者预后极差,因为局部或转移灶无法切除且化疗效果有限。因此需要新的策略治疗胆道癌。CLIN CANCER RES近期发表了一篇文章,报道了CART-EGFR细胞疗法治疗晚期无法切除的,复发/转移的EGFR阳性胆道癌的Ⅰ期临床试验结果。

胆道癌在东亚尤其是中国较为常见。诊断为晚期胆道癌的患者预后极差,因为局部或转移灶无法切除且化疗效果有限。因此需要新的策略治疗胆道癌。CLIN CANCER RES近期发表了一篇文章,报道了CART-EGFR细胞疗法治疗晚期无法切除的,复发/转移的EGFR阳性胆道癌的Ⅰ期临床试验结果。

研究纳入EGFR阳性(>50%)晚期无法切除/转移性胆道癌患者。紫杉醇(100-250 mg/m2)和环磷酰胺(15-35 mg/kg)治疗后输入CART-EGFR细胞。最终共有19例患者(14例胆管癌,5例胆囊癌)在6个月内接受1-3个周期的CART-EGFR治疗。CART-EGFR细胞具有一定耐受性,但是3例患者出现≥3级的发热/寒战。1/2级毒性反应包括粘膜/皮肤毒性和急性肺水肿,观察到与紫杉醇和环磷酰胺治疗相关的≥3级淋巴细胞减少和血小板减少。1例患者完全缓解,10例患者达到病情稳定。中位无进展生存时间为4个月。数据分析表明输入的CART-EGFR细胞内中枢记忆T细胞(Tcm)富集可以改善临床结局。

文章最后认为,CART-EGFR细胞免疫治疗是EGFR阳性晚期胆道癌患者安全有效的治疗策略。输入CART-EGFR细胞内中枢记忆T细胞富集可以预测临床反应。
