EASL 2014:钆塞酸为造影剂的MRI对HCC分期可改善患者预后

2014-04-14 佚名 dxy

肝细胞癌(HCC)根治性术后早期HCC复发率高,并且很多患者在治疗前已经出现原发灶的远处转移。钆塞酸是一种用于磁共振成像(MRI)的造影剂,具有灌注特异性和肝细胞特异性两种特性,与动态CT或MRI相比表现出较高的HCC检测敏感性。韩国首尔蔚山大学医学院峨山医学中心Kim等对此进行了一项临床研究,旨在确定是否按照钆塞酸造影下的MRI进行HCC分期,能够改善早期HCC患者的临床预后。 该项队列研究中,

肝细胞癌(HCC)根治性术后早期HCC复发率高,并且很多患者在治疗前已经出现原发灶的远处转移。钆塞酸是一种用于磁共振成像(MRI)的造影剂,具有灌注特异性和肝细胞特异性两种特性,与动态CT或MRI相比表现出较高的HCC检测敏感性。韩国首尔蔚山大学医学院峨山医学中心Kim等对此进行了一项临床研究,旨在确定是否按照钆塞酸造影下的MRI进行HCC分期,能够改善早期HCC患者的临床预后。

该项队列研究中,共纳入700例经动态CT扫描推测患单结节HCC的患者为研究对象。其中,323例还进一步应用钆塞酸造影剂行MRI检查(CT + MR组)、377例没有用此方法检查(CT组)。

结果显示,243例(34.7%)患者BCLC分期为0期、457例(65.3%)为A期,CT+MR组和CT组间没有统计学差异。应用钆塞酸造影剂行MRI检查评估后(CT+MR组),53例(16.4%)患者中额外检查出74个肝结节,34例(10.5%)患者因此而BCLC分期升级。

多因素分析显示,CT + MR组与CT组相比具有显著较低的HCC复发率(HR 0.72)及总体死亡率(HR 0.67);在298对经过倾向得分匹配呈对的分析中,CT + MR组依然具有较低的HCC复发率(HR 0.74)和总体死亡率(HR 0.61)

该研究表明,对于动态CT扫描推测为单结节的HCC患者而言,应用钆塞酸造影剂行MRI检查对HCC分期,与患者低复发率和更好的生存期有相关性。

JCO:台湾大学郑安理教授发现舒尼替尼治疗肝细胞癌结局不优于索拉非尼

研究要点: 本临床III期试验对比考察了舒尼替尼与索拉非尼治疗肝细胞癌的效果。 研究结果表明,舒尼替尼OS显著劣于索拉菲尼;舒尼替尼与较多且较严重的不良事件(AE)有关。 亚洲及乙肝感染患者的OS结局相当;接受索拉非尼治疗的丙肝患者可取得较好的OS结局。 在2013年9月30日在线出版的《临床肿瘤学杂志》(Journal of Clinical Oncology)上,发表了中国台湾大学郑安

Ann Surg:广西医科大学钟鉴宏等发现肝脏切除治疗BCLC B/C期肝细胞癌可取得较佳生存获益

研究要点: 目前在肝脏切除治疗BCLC B/C期HCC方面存在争议,本研究对肝脏切除与TACE的疗效与安全性进行了考察; 肝脏切除可取得优于TACE的生存获益;孤立性大型肿瘤、多结节肿瘤、大血管侵犯或PHT均非HR的禁忌症; 甲胎蛋白水平大于或等于400 ng/mL、糖尿病、大血管侵犯及PHT为BCLC B/C期HCC患者不良预后的独立预测因素。 尽管欧洲肝病研究协会与美国肝病研究协会

JID:1b期研究发现ITX5061治疗HCV效果有限

慢性HCV感染可引起肝硬化和肝细胞癌,是肝相关疾病发病和死亡的主要原因。现有的HCV治疗并不尽如人意,存在毒性、效果局限和顺应性差等缺点。尽管在细节方面仍存在诸多不清之处,但是HCV进入细胞所需要的细胞受体包括清道夫受体B类1型(SR-B1)、CD81、紧密连接蛋白1和闭锁蛋白。存在于多种细胞(包括肝细胞)膜上的整合跨膜蛋白ITX5061是一个高效的小分子SR-B1抑制剂。因为抑制SR-B1与血浆

EASL 2014:BCLC-B亚分类或对HCC患者预后有一定价值

2012年最新公布的巴塞罗纳临床肝癌分期系统(BarcelonaClinic Liver Cancer Classification,BCLC)-B亚分类标准,将存在中间阶段异质性的肝细胞癌(HCC)人群,按Child-Pugh评分、肿瘤负荷(最大到七个标准)、ECOG –PS和门静脉血栓形成,进一步划分为4个亚组。然而,该分类法尚未得到外部广泛地验证。 奥地利维也纳医科大学消化内科Hucke等对

EASL 2014:LY2157299治疗晚期HCC的安全性剂量评估

TGF-β信号转导与肝细胞癌(HCC)进展为中低分化肿瘤的过程有关,而抑制该信号转导通路可改善HCC患者整体生存率;LY2157299(LY)是一种TGF-β受体激酶抑制剂,可应用LY对HCC患者进行治疗。意大利巴里大学医学院传染病免疫内科Giannelli等对此进行了一项II期临床试验,旨在评估该药的安全剂量、疗效和药动学情况。 研究纳入对象为索拉非尼(SF)治疗后病情恶化者,或不能接受SF治疗

Gastroenterology:关新元教授发现OSGIN1与肝癌进展有关

来自香港大学、新加坡国立大学和中山大学的研究人员证实,氧化应激诱导生长抑制因子1(OSGIN1)等位基因失衡与肝癌的进展相关。这一研究发现于1月10日发表在国际胃肠病学杂志(,IF 11.675)上。 任职于香港大学和中山大学肿瘤防治中心的关新元(Xin-Yuan Guan)教授是这篇论文的通讯作者。其主要研究领域包括肿瘤发生发展相关基因、肿瘤干细胞及肿瘤微环境等。在
