Cancer Chemother Pharmacol:GC辅助性化疗治疗胆道癌患者1期研究

 虽然,吉西他滨联合顺铂(GC)已成为治疗局部晚期或转移性胆道癌(BTC)的一种标准化疗方案,但人们对BTC辅助疗法的益处还不清楚。日本学者研究确定了GC的标准剂量,其可作为行根治性切除术但未接受肝大部切除术的BTC患者辅助化疗的推荐剂量(RD)。为明确该方案在所有患者中的安全性和有效性还需深入研究。论文发表于《癌症化疗与药理学》[Cancer Chemotherapy and Phar

该研究中,纳入BTC患者的标准为:IB期或以上患者;行切除术但未接受肝大部切除术的患者。在第1和第8天,吉西他滨(1,000 mg/m2)和顺铂(25 mg/ m2)的起始剂量与标准剂量相匹配,每3周一次,持续24周。在前6周期间使用传统的3+3剂量探索设计(一剂量组3–6例患者)进行剂量限制性毒性(DLTS)测定,并进行了扩大患者队列研究。

结果如下:

起始剂量时,6例患者中有1例发生了剂量限制性毒性,即4级中性粒细胞减少。

之后,为评估RD,研究者在18例患者中进行了扩大队列研究,未见DLTs发生。

整个研究期间,最常见的3/4级不良反应为中性粒细胞减少(94%)和白细胞减少(56%)。非血液性毒性反应是可以控制的。

Science:癌症新疗法——以子之矛,攻子之盾

5月9日Science杂志上公布的一项成果,报道了一位43岁女性癌症患者绝处逢生的故事,这位患者患有晚期癌症,尽管进行了化疗治疗,但其癌细胞还是从她的胆管扩散到肝脏和肺部区域。 来自美国国家癌症研究所的研究人员对这位患者的基因组进行了测序,从她的免疫系统中找到了那些能攻击癌细胞中一个特殊突变的细胞,然后在实验室中培养这些免疫细胞,并将培养后的上亿个细胞注入回患者血液中
