和我父亲情况一模一样,复发时间都差不多。甲胎不敏感都一样。我建议你赶快吃上多吉美。多吉美会有效一段时间。转药大约每月5000元。与此同时,我强烈建议你在美国华盛顿大学做下一代基因测试,希望找到其他靶向药。我是最近才认识这位美国医生的,我父亲那时在301做了免疫组化,3个基因,6500多元,结果没有任何用处。我很后悔认识他晚了。我父亲没有做介入,仅供参考。
以下是我回答别的病友的:
华盛顿大学医学院的Tendon医生,基因测试费用4000美元(交给实验室的),他们可以一次性测49个基因,而且准确率达到99%。我当时不了解情况,父亲在301做了免疫组化,没有用。现在很后悔。
华盛顿大学在美国St Louis, 我和Bevan Tendon医生有直接联系。病理切片需要寄过去。医生拜托我,我只是帮忙,钱你可以直接汇过去,或者在病理中夹一张美元现金支票。时间需要4周。如果需要我也可以安排。

我问了华大基因,他们宣称测508个基因,其实只有49个有病理意义。测得太多会难以判断结果,而且精确性差。华盛顿大学医学院,是美国医院的前几名,可以达到测量结果99%的精确性。但是现实是找到靶向药的可能性是小于50%。另外医生的素质也直接影响到测量和解读的结果。Bevan Tendon医生师从美国基因学泰斗,在美国该领域是最好的医生之一。
无论怎样,如果你想走这条路的话,找到Bevan Tendon医生,无论是否找到靶向药,基因治疗和靶向药方面你可以不必再找其他医生了。我回头发些我和他的对话供大家了解情况。希望这个信息能够帮到大家。

抗PD-1明星药物Nivolumab,自2013年美国FDA授予快速审批通道后,2013年12月24日由日本小野制药向日本医药品医疗机器综合机构(PMDA)提出申请试药,并于2014年7月4日获得日本药监局批准上市,9月3日已在日本正式上市!这款药物在日本以商品名Opdivo出售。
据权威专家介绍,由于是新药的原因,日本对于该药物的使用管理很严格,需要向医院内的GCP中心等部门报备。此外,药物被设定为每100㎎,729849日元(约合4万3人民币)的价格。体重每1㎏就需要2㎎的使用量,因此体重50㎏的人则需要100㎎的使用量。并且,体重每增加10㎏用药剂量需要增加20㎎(150200日元,约合人民币8750元)。每3周为一个疗程,以静脉点滴的方式施药。抗PD-1药物Nivolumab适用的疾病仅限于黑色素瘤,对于其他的疾病,还处于试药的阶段.
2014年6月份,与日本小野制药合作开发Nivolumab的美国百时美施贵宝,就曾披露了关于癌症免疫药物nivolumab的临床三期研究结果,数据显示使用nivolumab的患者组比标准疗法总体生存率更高。2014年8月中下旬,百时美施贵宝联手生物巨头新基(Celgene),合作开发了Nivolumab+Abraxane免疫组合疗法,以彻底挖掘Nivolumab的临床潜力。小野制药也表示,虽此药物目前只适用于黑色素瘤,但它计划为该药物申请国民健康保险项目,以免费为患者提供这个广受瞩目的药物。该公司还打算继续研究该药物在其他癌症方面的用途。事实上,PD-1抗体的作用是广谱的,目前临床试验中已经包括肺癌、肾癌、胃癌、结肠癌、卵巢癌、乳腺癌、皮肤癌和脑肿瘤等。而Nivolumab的免疫治疗研究已经在黑色素瘤、肾细胞癌、非小细胞肺癌中开展。

AACR:PD-1抗体药物III期试验结果喜人
中国肿瘤化疗 来源:医脉通发布日期:2013-4-12
在美国癌症研究协会(AACR)第104届年会上,一种新型抗体药物Nivolumab (由Bristol-Myers Squibb公司研发的新药) 已经应用在黑色素瘤、肾细胞癌、非小细胞肺癌的治疗中,这引起了与会专家的极大兴趣。目前该药已经处在3期临床研究中,有望成为今后肿瘤免疫治疗领域的一项重大突破。
这是一个抗癌药物研发过程中意义非凡的时刻。一种新药的3期临床试验同时在3种不同的癌症中进行。Nivolumab (由Bristol-Myers Squibb公司研发的新药) 的免疫治疗研究已经在黑色素瘤、肾细胞癌、非小细胞肺癌中开展,Suzanne Topalian博士在美国癌症研究协会(AACR)第104届年会上说到。她来自于马里兰州巴尔的摩的约翰霍普金斯大学医学院和Sidney Kimmel综合癌症研究中心。
在接受采访时,Topalian博士告诉记者,“将一种新药用于如此之多的不同癌症的临床试验是史无前例的”。
正是因为看到了Nivolumab在1期试验中的有效结果,这项3期临床试验才得以进行,Nivolumab的1期临床试验之前被称为BMS-936558和MDX-1106。这种药物属于单抗药物,它能够中和程序性死亡因子-1(PD-1)蛋白,PD-1蛋白是一种肿瘤应答元件,能够使肿瘤逃避免疫系统的攻击。
Nivolumab的研制去年被认为是癌症治疗领域里一件重量级的事件,这是基于早先的研究结果,该结果表明Nivolumab对多种癌症的持续肿瘤反应率达到20%-30%。用专家的话讲,这种新药突破了持续肿瘤反应率在10%-15%的限制,这种限制在过去30年里一直阻碍着癌症免疫治疗的发展。
肿瘤免疫治疗——并非其他类型的癌症治疗(注:这里是指除了文中提及的黑色素瘤、肾细胞癌、非小细胞肺癌之外的癌症)——能够进行到3期临床试验并不是偶然的,Topalian博士指出。
“在许多方面,由T细胞和抗体组成的适应性免疫系统是一个完美的抗肿瘤体系”,她在会议上告诉听众。
Topalian博士对癌症研究领域的主流观点发起了挑战。
“现在普遍被接受的观点是肿瘤是遗传性疾病,”她解释说,单个肿瘤的信号转导系统存在成百个突变和改变,这便是个体化医学治疗方法的基础所在。
但是,遗传模式是一个很大的问题。靶向治疗所产生的耐药性问题“有着自己的局限”,她指出,“抑制一条信号转导通路可以导致另一条通路出现问题。”
同时,Topalian博士也提出了另一种观点,他认为”癌症就是免疫系统紊乱了”。
免疫治疗具有许多优势,原因在于肿瘤突变能够被特异性的识别并被免疫系统靶向杀灭。而且,她说到”随着肿瘤的演化,免疫系统能够适应和进化“。
Topalian博士向大会展示了一张关于PD-1基因的鉴定及抗PD-1研究发展的时间表。这张时间表并不是他的研究团队制作的,它向人们传达了FDA 将于2015年批准抗PD-1药物的信息。
”如果Nivolumab获批,肿瘤免疫治疗领域将受到极大的鼓舞,“Priyanka Agharkar谈到,她来自纽约市巴法罗罗斯维尔公园癌症研究中心。除了sipuleucel-T (Provenge,普罗文奇)用于治疗前列腺癌和易普利姆玛(Yervoy)用于治疗黑色素瘤之外,”很少有抗体药物用于治疗癌症“,她说到。
现在已经存在许多针对抗PD-1药物和抗PDL1药物研发的竞争。事实上,罗氏的基因泰克、葛兰素史克、CureTech公司、默克、MedImmune公司已经出台了相关研究计划。

以前这些我们都在301测过,没有用上。你想了解华盛顿大学基因测试什么信息,我帮你问下。全球第一个人类基因测序就在该校进行的。 我和Tendon医生有直接联系,可以微信。我和他太太很熟,他太太是中国人。我们以前都在美国留学。
以下是我们的对话,有空我翻译一下。
With ngs, the issue is that the test produces lots of information but you need a good physician with clinical experience and understanding to figure out the significance in clinical terms what the sequence variants mean for the patient and their disease.
Bevan
I don't know too much about Chinese lab.certainly there are others here in us, but washU is world leader for cancer sequencing.The first human cancer genome was fully sequenced at this institution for a patient with acute myeloid leukemia and GPS division here has experience processing approx 2000 cases for clinical ngs and cancer testing. It will test 49 genes with potential established therapeutic targets in the literature. Some companies here like foundation clinical medicine offer up to 250 genes but many other genes do not have clear cut clinical significance
Rate of identification of cancer specific therapeutic target is less than 50%.Probably lower.In lung cancer most common targets are egfror alkmutations which have specific drugs.Stomach and liver cancer I will have to check.Everyone here is very excited about this technology. However, it is important to have realistic expectations about the potential yield.I will let you know liver and stomach cancer ngs let me research a little
Majority of patients I review are colon,lung,head and neck cancer
Also ngs testing can be done for all cancer types not just blood cancer leukemia
Other gene testing is prohibitively expensive to test multiple genes at same time. Conventional single gene sequencing prior to ngs was Sanger Sequencing and can cost up to several thousand dollars for just 1 gene.Clinical ngs is revolutionizing personalized medicine.If there can be a pipeline of patients from China and I had a lab of my own this could be very good business. Trust could be built up in first phase by sending to washU where I will have my name on the reports because I am generating the clinical report.
Will
what is the difference of next generation sequencing and other gene test?
Bevan
Hello,next generation sequencing is a major part of my job currently. I interpret the data and generate the report. The laboratory takes the patient materialand extracts the DNA and runs it through the sequencer.The patients in China should have access to their ffpeblocks and slides.After surgery for either excision or other biopsy the tissue is usually processed and made into the blocks which are then cut very thin and sections are mounted into a glass slide and reviewed under microscope by a pathologist.Hope that answers your questions.
We would need his formalin fixed paraffin block biopsy from his cancer.The patient should be able to obtain this material and have it shipped over.
We get testing requests for therapeutic target identification using next generation sequencing from international patients.Last month one of the doctors brother who lives in Germany had his brain biopsy material sent over and I interpreted his testing and we identified an antitumor target for his brain cancer
http://gps.wustl.edu/cancer
????,????????????,?????22?,they went to mayo clinic in US in December this year ,conclusion is it can not be treated,they want to try targeting antitumor drugs,and all other possible treatment, any suggestion?
Bevan
Precise data for frequency of mutations that are clinically relevant isdifficult to get from companies because they will always inflate the number for marketing purposes.Even at washUmy experience had been only 10 percent of ngs cases yield useful clinical information
With ngs the issue is that the test produces lots of information but you need a good physician with clinical experience and understanding to figure out the significance in clinical terms what the sequence variants mean for the patient and their disease.
Will
this is the brochure from BGI, the major chinese player.i did a little research, there are many small agencies doing gene tests too,mostly for parent children identification, prenatal screening, also child talent gene tests, etc.serious testing are BGI and one lab from souel univ. korea. BGI says i will tests 508 genes.
Here in America companycalled clinical foundation medicine does over 200 genes.WashU does 151 but only 49 have been determined to be best for clinical report. Many genes lack clinical associations in specific diseases and forpersonalized medicine the number of genes for drug targets is still low overall.There are multiple technologies for gene sequencing but hybrid capture for targeted panel analysis is probably what bgiis doing for 500 genes
For marketing people might think more is better but when you generate data for genes that lack clear clinical association it becomes frustrating because then you don't know what conclusion to make
Also when you do more focused testing not only does that streamline interpretation to focus on genes that may have clinical association there is another major benefit
You can perform more sequencingwhere you sequence the same gene hundreds or thousands of times (you increase the "coverage depth").This enhances sensitivity significantly and improves rate of detection for potential disease related mutations in the targeted genes
I don't know what coverage depth is in the bgipanel targeting 500 genes but that would be an important point of difference. There is very precise data available to demonstrate mutation detection rate based on sequencing experiments on knowngold standard specimens.WashU has approximately 99% sensitivity and specificity for the clinically reported genes which is a very important point to consider when comparing platforms and different tests
In general when you widen The target capture space and increase number of genes then the coverage depth is reduced for each individual gene
But that is rule of thumb

另外,他们这样一个一个基因检测的肯定不是最新技术。最新技术就是NGS下一代基因测序,可以一次性测出多个结果,而且费用便宜很多。深圳的华大基因宣称可以一次性测508个基因,可能就是类似的技术。但是测得太多,结果可能失去准确性,而且变得难以判断。华大收费好像15000吧。你可以问问,在上海应该有服务人员。华盛顿大学可以测151个基因,但是只有49个有临床意义。
