NEJM:Tisagenlecleucel用于复发或难治性弥漫性大B细胞淋巴瘤

2018-12-04 zhangfan MedSci原创

研究认为Tisagenlecleucel是有效的复发或难治性弥漫性大B细胞淋巴瘤治疗手段

接受一二线或干细胞移植后复发的弥漫性大B细胞淋巴瘤患者其预后很差。在IIa研究中,CART疗法Tisagenlecleucel可有效清除CD19阳性B细胞,具有较好的应用前景,近日研究人员公布了其II期临床结论。

复发或难治性弥漫性大B细胞淋巴瘤或接受干细胞移植后复发患者参与研究,研究的主要终点为总响应率。

93名患者参与研究,平均随访14个月。总响应率为52%,40%的患者出现完全缓解,12%的患者存在部分缓解,各亚组缓解率相近。在最初缓解后12个月,患者的无复发生存率为65%。最常见的3-4级不良事件包括细胞因子释放综合征(22%)、神经系统事件(12%)、持续28天以上的细胞病(32%)、感染(20%)和发热性中性粒细胞减少(14%)。3名患者在输注后30天因疾病进展死亡,但与治疗无关。

研究认为Tisagenlecleucel是有效的复发或难治性弥漫性大B细胞淋巴瘤治疗手段。

Blood:Pan-SRC激酶抑制剂可阻断非霍奇金淋巴瘤的B细胞受体致瘤信号转导

中心点:抑制对依鲁替尼耐药的患者的BTK,可改变信号肿瘤依赖性,并促进上调MYC。LYN、FYN和BLK多重靶点抑制对独立于其分子亚型的DLBCL患者治疗效果显著。摘要:对于弥漫性大B细胞淋巴瘤(DLBCL),激活B细胞受体(BCR)可促进多种对肿瘤增殖至关重要的致瘤信号。抑制Bruton'酪氨酸激酶(BTK),BCR的下游靶点,仅用于治疗DLBCL患者亚群时效果显著。Elena Battiste

Blood:弥漫性大B细胞淋巴瘤通过激活存活信号通路或获得影响药物与靶点结合的EZH2突变,从而对EZH2抑制剂耐药

中心点:EZH2抑制剂耐药性主要是因为激活了存活信号通路和获得影响药物与靶点结合的EZH2突变。不同的EZH2抑制剂的耐药机制不同,因此,肿瘤细胞对一种EZH2抑制剂耐受,可能会对其他种抑制剂敏感。摘要:对靶向治疗的耐药性越来越普遍。研究人员发现对不同靶向治疗耐受性的发生机制大致相同。在本研究中,Malik Bisserier等人利用该信息探究携带EZH2突变的弥漫性大B细胞淋巴瘤(DLBCL)对

J Clin Oncol:奥秘皆在细微处:诊断治疗间期与新诊断弥漫大B细胞淋巴瘤预后相关

长久以来,如何提高肿瘤临床试验结论的科学性和普适性备受关注。以往,研究者往往通过严密的试验设计、严谨的知情同意条款和科学的分析来控制偏倚。美国梅奥诊所学者Maurer等的研究结果发现,临床试验中人们甚少关注的诊断治疗间期与预后显着相关,该研究结果近日发表于JCO杂志上。

Blood:HSP110通过稳定MyD88维持ABL-DLBCL的NF-κB信号

中心点:HSP110通过稳定MyD88维持ABL-DLBCL的NF-κB信号。HSP110在ABL-DLBCL患者的淋巴结细胞中高表达,与MyD88的表达水平相关。摘要:激活的B细胞弥漫性大B细胞淋巴瘤(ABL-DLBCL)是一种侵袭性的淋巴增殖性疾病,涉及慢性NF-κB激活。BCR和MyD88信号通路组分的几个突变,如MyD88 L265P,均与上述异常激活相关。其中,热休克蛋白——HSP110

Blood:在弥漫性大B细胞淋巴瘤中,B细胞受体介导的NFATc1激活可诱导IL-10/STAT3/PD-L1信号

中心点:在DLBCL细胞中,B细胞受体(BCR)介导的NFATc1激活刺激免疫抑制IL-10/STAT3/PD-L1信号通路。用BTK的小分子抑制剂封闭BCR介导的NFATc1激活,可下调DLBCL细胞的IL-10/STAT3/PD-L1信号。摘要:目前对PD-L1在B细胞淋巴瘤细胞中的表达及调控的了解有限。研究PD-L1在B细胞淋巴瘤中的表达调控机制或许可鉴别出能预测采用用抗PD-1/PD-L1

Blood:肿瘤抑制信号轴—TGF-β/SMAD1/S1PR2—在弥漫性大B细胞瘤中普遍失活,促进肿瘤细胞增殖

中心点:鞘氨醇-1-磷酸受体2(S1PR2),肿瘤抑制因子,转录受 TGF-β/TGF-βR2/SMAD1轴调控。SMAD1表达异常缺失在DLBCL中很常见,促进B细胞在体内外扩增。摘要:在弥漫性大B细胞淋巴(DLBCL)中,鞘氨醇-1-磷酸受体S1PR2及其下游信号通路常保持沉默,主要是通过突变失活或通过致癌转录因子FOXP1的负性调控。在本研究中,研究人员对S1PR2表达的上游调控进行研究发现
