CSCO :肿瘤二代测序技术应用重在规范

2016-05-10 张思玮 中国科学报

“二代测序技术应用于临床肿瘤精准诊治最关键的问题,是规范测序公司的标准和操作方法,只有规范的技术才能保证后续的精准发现和精准治疗。”前不久,中国临床肿瘤学会(CSCO)理事长吴一龙教授在《二代测序技术应用于临床肿瘤精准诊治的共识》(以下简称《共识》)发布会上表示,《共识》旨在为二代测序(NGS)技术应用于临床肿瘤驱动基因分析,提供相关指导性建议并规范临床实践。NGS是一种高通量的大规模平行测序技术

“二代测序技术应用于临床肿瘤精准诊治最关键的问题,是规范测序公司的标准和操作方法,只有规范的技术才能保证后续的精准发现和精准治疗。”前不久,中国临床肿瘤学会(CSCO)理事长吴一龙教授在《二代测序技术应用于临床肿瘤精准诊治的共识》(以下简称《共识》)发布会上表示,《共识》旨在为二代测序(NGS)技术应用于临床肿瘤驱动基因分析,提供相关指导性建议并规范临床实践。


NGS是一种高通量的大规模平行测序技术,可同步获得肿瘤患者个体特定样本中数以十亿计的DNA碱基序列信息,是发现已知和未知疾病相关基因变异的高效手段。尽管在单基因遗传病、产前诊断等方面已广泛应用,但当前NGS用于肿瘤基因检测仍缺乏统一规范和共识。

我国肿瘤患者数目庞大,基因诊断和检测需求巨大,但实际应用中,因为准入门槛低、缺乏业界公认的指导规范,可能存在检测质量低下、结果准确性差、解读不专业,甚至盲目追求基因检测结果等现象。

鉴于此,为了推动实现NGS临床检测的规范化,CSCO理事长吴一龙教授、CSCO副理事长秦叔逵教授于2015年指导成立了中国肿瘤驱动基因分析联盟(CAGC),并启动“精准肿瘤学研究项目(CAGC POI)”,邀请实验室癌症遗传学家、临床肿瘤学家、生物信息学专家、病理学家等专业成员撰写《共识》。

《共识》的主要目的是保证临床实践中得到的二代测序检测数据准确可靠,对临床决策有所帮助,最终可以使患者获益。‘精准诊断’先行,才有治疗的‘精准方案’及对患者疾病全程的‘精准管理’。疾病防治过程中,精准诊断是三个精准的首要环节,是起到‘先进雷达搜索攻击目标靶点’式的关键作用。”《共识》的主要执笔人、广东省肺癌研究所张绪超教授说。

《共识》不仅阐述了NGS技术质量需求、临床肿瘤相关NGS检测内容、样本处理、测序流程、数据管理、信息学分析、结果报告解释和咨询及知情同意、NGS用于研究与诊断的区别、CAGC POI项目NGS测试的监督等9方面内容,还重申了尊重患者的利益,患者在接受检验前须知情同意、获得相关遗传学咨询,以确保患者知晓基因检测的目的、利弊及测试的局限性。

此外,《共识》同时配发《NGS检测报告格式化模板》用以指导检测结果的临床报告,目的是确保检测方以标准化、全面充分但又简明易懂的方式为临床医生提供信息,协助其用于患者的靶向治疗方案的决策。

不过,由于肿瘤驱动基因研究以及基因检测技术进展非常迅速,专家也表示,未来CAGC POI专家组将广泛收集相关意见和建议,在这一版《共识》的基础上,指导《共识》的下一步修订和更新。(张思玮)

吕雪梅教授:肿瘤内部和之间的异质性演化及其医学意义

4月23日,肿瘤异质性学术研讨会在上海好望角大饭店进入第二天的议程,中国科学院北京基因组研究所研究员吕雪梅博士发表了题为《肿瘤内部和之间异质性的演化及其医学意义》的演讲。吕雪梅教授创造性地运用群体遗传学模型分析了肿瘤内部和肿瘤之间的异质性,发现肿瘤内部异质性的演化实质上是细胞水平的非达尔文过程,而自然选择可能在肿瘤间的异质性中扮演重要角色。 吕雪梅教授表示,肿瘤发生时体细胞演化的过程,正如自

科学家尝试用组合式靶向疗法剿灭癌症

  如显微镜图片所示,肿瘤细胞能够对化疗药物奥沙利铂等产生耐药性。图片来源:Margaret Oechsli 我们总是对患者说癌症会以达尔文的自然选择方式在体内进化,但是我们并没有足够的证据证实这一点。 大约6年前,Alberto Bardelli跌入了科研低谷。Bardelli是意大利都灵大学癌症生物学家,他一直在研究癌症靶向疗法——针对导致肿瘤生长的
