JAMA:胰腺癌患者存活时间竟由这四种基因决定!

https://www.ncbi.nlm.nih.gov/pubmed/?term=Association+of+Alterations+in+Main+Driver+Genes+With+Outcomes+of+Patients+With+Resected+Pancreatic+Ductal+Adenocarcinoma


近日,来自美国罗切斯特大学,哈佛大学丹娜法伯癌症研究院和斯坦福的科学家研究发现胰腺癌患者存活的时间长短竟取决于四种基因。

该研究对应文章则发表于最新上线的JAMA杂志,名为Association of Alterations in Main Driver Genes With Outcomes of Patients With Resected Pancreatic Ductal Adenocarcinoma。

在这项研究之前,胰腺癌存活时间于具体基因的内在联系尚未被科学家所阐明。在这项研究中,科学家对356例可以手术取出癌组织的胰腺腺癌患者进行了深入的研究,而这一巨大的癌症病人总量和样本量是之前所有相关研究所望尘莫及的。同时,腺癌也是胰腺癌患者中最为常见的类型。

在这项研究中,90名胰腺癌患者在罗彻斯特大学医学中心Wilmot癌症研究所接受了治疗;其余的胰腺癌患者则在哈佛大学 Dana Farber 癌症研究所,波士顿妇女癌症中心以及斯坦福癌症研究所接受了治疗。科学家对所有完成肿瘤切除病例的癌组织和附近正常组织进行了DNA提取以及二代测序。

研究结果表明,与正常组织细胞的基因组相比,胰腺癌细胞基因组中的突变主要集中于KRAS,CDKN2A,SMAD4和TP53四个基因。研究结果显示,与上述单个或两个基因变异的患者相比,具有三或四个上述基因变异的患者具有更差的无病生存期(手术后至癌症复发)和总生存期(从手术到死亡)。

研究的合作者,Wilmot癌症研究所血液肿瘤科主任Aram Hezel博士说:“这项研究有助于我们理解胰腺癌的具体遗传特征如何影响病人个体的预后,同时,这项研究也能为我们提供更多的知识来指导患者的临床治疗并更加科学地设计未来的相关研究。”

 “胰腺癌是最具侵袭性的癌症,一般情况下,胰腺癌患者的生存几率非常低。可以接受手术治疗的一部分患者通常能够存活更长时间,同时,也存在一些患者能够受益于手术前的化疗。”Hezel说,“对胰腺癌遗传背景的阐明可以更好地帮助我们了解每个胰腺癌患者疾病的进展情况。”

Eur Radiol:诊断胰腺癌就单单开个磁共振检查单?磁共振弹性成像在诊断胰腺癌中价值!

胰腺导管腺癌是常见的一种胰腺癌的类型,它可以分为4期。一期无残留的肿瘤切除生存时间要大大长于其他时期的导管腺癌,因此做好尽早的发现导管腺癌,对患者有着重要的意义。另外人们又常常不能够尽早的发现导管腺癌,能施行一期无肿瘤残存的手术人数只有5%。所以提高导管腺癌的诊断机制对导管腺癌的治愈有着重要的意义。本研究旨在验证MR弹性成像(MRE)并将其与血清CA19-9在鉴别良恶性胰腺肿块的诊断价值,尤其是胰

Gastroenterology:胰腺癌血管生成机制获揭示

天津医科大学肿瘤医院胰腺肿瘤科郝继辉、任贺课题组独立完成的最新研究成果证实,免疫调节因子IL-35通过细胞浸润,诱导其分泌促血管新生因子,来促进胰腺癌的血管新生。研究解析了胰腺癌血管生成的新机制,进而阐明了胰腺癌对于传统抗血管生成药物治疗无效的原因,为胰腺癌的抗血管新生治疗提供了新的靶点。该研究论文日前发表在国际胃肠病领域排名第一的杂志《Gastroenterology》上。

ANN ONCOL:非转移性胰腺癌化疗后如何选择需进行手术切除的患者

交界性(BL)或局部晚期(LA)胰腺癌患者通常需要先进行化疗后选择合适的患者进行手术切除。ANN ONCOL近期发表了一篇文章,研究化疗后可以进行切除的患者的选择标准。

Sci Rep:循环miRNA-21-5p或是早期胰腺癌诊断的生物标志物

世界范围内胰腺癌(PC)是一种高致命性疾病,其早期阶段常常被误诊。探索新型非侵入性生物标志物必定会使PC患者受益。最近,体液中的循环miRNAs正在成为PC诊断的非侵入性生物标志物。在本研究中,我们首先对21个已发表的miRome谱分析研究进行了全面的稳健的秩聚合(RRA)分析。我们统计确定并临床验证PC患者中的miRNA表达模式。这些miRNAs包括四个上调miRNAs(hsa-miR-21-5

JAMA Oncol:四个基因决定胰腺癌患者的生存期

切除胰腺腺癌的患者出现疾病复发的风险很高,但很少有生物标志物可用于预测患者结果。来自罗切斯特大学医学中心的研究人员就对胰腺癌中4种主要驱动基因的改变以及癌症切除后的患者预后进行了评估。

[胰腺癌年会]虞先濬教授畅谈胰腺癌治愈之路

胰腺癌“癌中之王”的称号可能会让很多人闻风丧胆,临床肿瘤专家对胰腺癌的治疗可谓是绞尽脑汁、鞠躬尽瘁。胰腺癌的治疗由原来的单一手术治疗到现在的药物治疗等的出现,给患者带来了更多的选择。2017年10月27日-29日,中国抗癌协会胰腺癌专业委员会年会在天津召开。
