JCO:抗癌药物评价工具的临床获益如何?

近几年,美国临床肿瘤学会(American Society of Clinical Oncology ,ASCO)发布了抗癌药评价体系“价值框架”(value framework),又称为ASCO价值框架;欧洲肿瘤内科学会(European Society of Medical Oncology,ESMO)推出了一款用于协助肿瘤临床医师为其患者评估最为有效抗癌药物的工具——ESMO-MCBS,但二者的类似的临床获益情况尚不清楚。

来自英国和加拿大的研究认为,目前还不清楚他们是如何影响质量调整生命年(QALY)和资源管理间的关系。因此,研究人员设计了该研究,对其进行了探讨。

研究人员检索了2006-2015年8月间被美国食品和药物管理局(FDA)、欧洲药品管理局和加拿大卫生署批准的抗肿瘤药物的随机临床试验,同时,至少有两个评论员使用ASCO价值框架1(v1)、ASCO价值框架2(v2)和ESMO-MCBS对每一个试验进行了评分。计算斯皮尔曼相关系数(spearman correlation coefficient)来评估构想效度(价值框架之间)和效标效度(国家卫生和保健研究院[the National Institute for Health and Care Excellence,NICE]和加拿大肿瘤药物共同评议组织[the pan-Canadian Oncology Drug Review,pCODR]的不利质量调整生命年)。对NICE/pCODR推荐和评分之间的关联进行了研究。使用内部相关系数对评分者间信度进行了评估。

研究共涉及了109项随机对照临床试验,得出了108个ASCOv1评分,111个ASCOv2评分和83个ESMO评分。ASCOv1 vs ESMO、ASCOv2 vs ESMO,和ASCOv1 vs ASCOv2之间的相关系数分别为0.36(95% CI,0.15-0.54),0.17(95% CI,-0.06-0.37),和0.50(95% CI,0.35-0.63)。与NICE的QALY相比,相关系数分别为0.45(ASCOv1),0.53(ASCOv2),和0.46(ESMO);pCODR QALYs中,相关系数分别为0.19(ASCOv1),0.20(ASCOv2),和0.36(ESMO)。价值框架和NICE/pCODR推荐间没有显著相关性。在所有框架间评分员信度都很好。

研究人员认为,ASCO价值框架与ESMO-MCBS间的相关性较弱,同样他们与QALYNICE/pCODR推荐的相关性均较弱,这提示不同的临床构建有利于测量。更新ASCO价值框架后,ESMO-MCBS的构建聚合效度没有提高。

“可治百病的抗癌神药”是如何炼成的?

首先,这是一篇旧闻,不是新闻。 早在2010年8月23日,popular science网站上发布一篇新闻稿(Corey Binns.A PROTEIN KILLER COULD TREAT ALL CANCERS, AND POSSIBLY ALL ILLNESSES.Popular Science, Aug 23, 2010.)。在这篇新闻稿中提到美国一家Alnylam生物技术公司利用

Cell:肠道菌会改变抗癌药物的活性

美国UCL大学领导的研究分析了线虫中药物和营养的微生物过程,该研究显示癌症药物的活性变化取决于生活在肠道内的细菌种类。这一发现凸显了操纵肠道菌和饮食来改善癌症治疗的潜在益处,以及了解个体间药物效用差异的价值。这篇研究文章发表在4月21的 cell上,通过一个新的高通量筛选方法,阐明了宿主之间复杂的关系,以及肠道微生物与药物的作用。研究人员回应媒体采访研究的领导者Filipe Cabreiro博士说

Cell子刊:为何抗癌药物无法渗透实体瘤?肿瘤内部压力大是重要原因

许多癌症治疗药物疗效不佳,其中一个原因就在于这些药物无法渗入实体瘤内部的高压环境。根据发表在国际学术期刊Biophysical Journal上的最新研究结果,透明质酸可导致肿瘤内部形成胶状液态压力环境,是导致癌症药物无法渗入的重要原因。   来自美国西雅图弗雷德哈金森癌症研究中心的Sunil Hingorani表示:"我们发现肿瘤内部的胶状液态环境是胰腺癌产生药物抵抗的主要机制

Cell:微管结构助力抗癌药物开发

微管是直径仅有几纳米的微管蛋白的空心纤维,其可以形成活细胞的骨架并且在细胞分裂的过程中扮演着重要的角色;近日,刊登在Cell上的一篇报告中,来自加利福尼亚大学等处的研究者通过联合研究,将冷冻电镜技术同特殊的成像分析方法进行结合,成功地从原子视野对微管进行了观察,这对于理解微管在末端结合蛋白中的功能提供了一定帮助,而末端结合蛋白则可以调节微管的动态不稳定性。在有丝分裂期间微管可以拆解重新形成纺锤体

JCI:抗癌药物剂量可决定癌细胞命运

最近,来自意大利的研究人员在国际学术期刊JCI上发表了一项最新研究进展,他们在这项研究中深入分析了癌症病人对不同剂量酪氨酸激酶抑制剂舒尼替尼产生应答和抵抗的双重机制,这为该药物的应用以及解决病人对该药物的耐受问题提供了重要信息。苹果酸舒尼替尼是一种口服的小分子多靶点受体酪氨酸激酶抑制剂。作为一种ATP竞争拮抗剂,舒尼替尼能够抑制包括VEGFR,PDGFR和干细胞/">干细胞因子受体(

Environmental Microbiology:天然抗癌药物的真正起源

几十年来,科学家已经知道ET - 743是一种从海洋无脊椎动物中提取的称为被囊红树蝰的药物,该药物可以杀死癌细胞。在欧洲和美国临床试验中该药物已经批准用于病人。科学家们怀疑红树蝰被囊动物是一种海鞘类生物,实际上并不能生产ET - 743。但该药(曲贝替丁)的确切起源仍是一个谜。 通过使用先进的测序技术分析被囊类动物中微生物基因组,密歇根大学的研究人员能够分离ET- 743基因蓝图的制造者——
