关于检查点抑制剂可能造成的瘙痒和皮疹的治疗方法
;Management — Most checkpoint inhibitor rashes can be treated with topical corticosteroid creams. If pruritus is a prominent symptom, oral antipruritics (eg, hydroxyzine, diphenhydramine) can be helpful. Severe rashes (grade 3/4) should be managed with oral corticosteroids, and treatment with checkpoint blockade should be held as per established management algorithms (http://www.accessdata.fda.gov/dr ... y_2012-02-16_Full.p df).

Severe rashes such as Stevens-Johnson syndrome/toxic epidermal necrolysis have been reported in rare cases. Such reactions typically require hospitalization, intravenous steroids, dermatologic evaluation, and vigilant monitoring to treat abnormalities in fluid and electrolyte status. Any rash that does not promptly resolve with corticosteroid creams or shows signs of blistering should be evaluated promptly by a dermatologist and biopsy considered. "

关于防止TKI的耐药,对于EGFR+的患者们,这个谈论了有关9291和navitoclax 的联用。
navitoclax 是BCL2抑制剂,在一个还在阶段一的实验中被研究对于EGFR突变含有TM的人。

实验:NCT02520778

丢失T790M被发现在活检和circulating plasma DNA中,来自获得对第三代T790M突变特别抑制剂耐药的患者,记录在27%的获得对9291耐药的患者中。

有一个好的方法对疾病控制,尤其是对T790M成分多种的情况,或许理想的涉及一代和三代EGFR TKI联用(双重抑制,有用阿法和西妥昔单抗的或许也算双重抑制),也谈论了有关双重抑制或替代的剂量安排(比如断断续续的每周的高剂量阿法治疗+每天低剂量的特罗凯)成功的预防在靶上耐药改变,耐药也许会被彻底挫败。

三种可能的方法来治疗(cure)转移性肿瘤(metastatic solid tumors )包括阶段四的肺癌:
1、        使免疫系统来做这个工作,为了打到这个你需要启动一个足够多样、强力、持久的免疫反应来了解癌细胞,或无限期的使其在被检查中。最近很多免疫治疗方面的调查在讨论这个。
2、        你用混合药物来管理同时多或少的杀死癌细胞,做手术取活检根据结果用药不错。

局部缺血或低氧或许是个可以减缓耐药的环境?但是这种环境不容易

3、        If one can predict how a tumor will respond to a certain drug, one can then perhaps also devise clever strategies for how to avoid tumors becoming resistant. Dr Robert Gatenby of Moffitt in Florida is a pioneer in this field. His seminal work, Adaptive Therapy (https://www.ncbi.nlm.nih.gov/pubmed/19487300) basically outlines the concept.

在一个实验中,用药被给予最大耐受剂量时肿瘤最大,用节拍化疗时肿瘤最小。同时也是维持剂量(见下图描述),使肿l进展缓慢的剂量,肿l进展结果最缓慢。(但人和人情况还是不一样的,实验有一定参考性)

Two different experiments as described in the text. The y-axis is the mean tumor volume for the four animals in each experimental group, and the x-axis is the time from s.c. inoculation of 107 tumor cells. Each experiment included four animals in three experimental arms: (a) control (vehicle only); (b) “standard” high dose therapy consisting of 60 mg/kg q4 days for 3 doses; (c) adaptive therapy which begins with a dose of 50 mg/kg and then adjusts the dose to maintain a stable tumor volume. The arrows on the x-axis represent days in which therapy was given in the adaptive group. In the top experiment, the doses are (from left to right) 50, 40, 40, 30, 30, 20, 20, 10, 10, 10, 10, 10, 10, 10, 10, 10 mg/kg. In the lower experiment, the doses are 50, 50, 40, 40, 30, 20, 20, 10, 10, 10, 10, 10, 10 mg/kg.

一个实验表明,新产生的耐药细胞会比原来的更难以生存,新耐药细胞很难扩展,旧细胞的扩增会以新细胞为代价、如果耐药细胞在药物调整(尽量稳定肿瘤生长的剂量)之前就出现了,并且同时又使用了最大耐药剂量希望把肿瘤打压的越严重,那么这个抑制效应(旧细胞的扩展会压制新细胞的效应)将会被移除,并且会导致耐药细胞急速增长。(最大剂量慎重考虑)

那么如果9291耐药,先不着急加大剂量,上新药也该上合适剂量为好。(比如正常剂量的大部分?)

还是稳定剂量最好,保持肿瘤较小的状态比较长时间,同时保留对现有环境稳定的细胞,对耐药细胞造成抑制。(见下面)

最大剂量肿瘤耐药反弹快。

Progression of tumor properties with time in initial response to different therapeutic strategies. All graphs use two populations, FS and ER, the first being fit and therapy sensitive, the second environmentally resistant. The top left graph (Total tumor size) shows that MTD therapy results in a better initial result but the tumor promptly acquires resistance and recurs. Metronomic therapy (METC, METH, and METL) also reduces the tumor and is able to keep it stable for longer, but eventually, the resistant populations emerge once sensitive population is depleted (top right, Phenotypically sensitive). As shown in Fig. 3, these resistant populations result in tumor regrowth and patient death. Tumors treated with adaptive therapy (ADP) decrease in volume much less than with the other therapies but then maintain a stable tumor size for a prolonged period of time. Control (CTRL) corresponds to untreated tumors.

关于稳定剂量带来的多少好处,见下图。

Simulations for application of five therapy strategies: (a) MTD; (b) adaptive therapy; (c) metronomic therapy (continuous infusion); (d) metronomic therapy (high-frequency administration); and (e) metronomic therapy (low-frequency administration). Four combinations of mixed cell populations that include FR with high free-field fitness and high sensitivity to therapy, and R with lower fitness and low sensitivity to therapy, S with low fitness and high sensitivity, and ER with high intrinsic sensitivity and fitness but in an environment that restricts proliferation and response. Combinations shown in (a) “FS and R,” (b) “S and FR,” (c) “FS and R and ER,” and (d) “FS and ER.” The results show that at day 1,500 of tumor growth (1,100 d after initiation of therapy), the tumor treated using the MTD strategy was largest whereas those treated with metronomic therapy were smallest. When the simulations were run until the tumor burden achieved the lethal threshold, all patients in the MTD and metronomic therapies succumbed to their disease. However, the tumors treated with adaptive therapy remained stable even after a period exceeding 10,000 d.

P3.02c-048 - A Phase I/II Trial Evaluating the Combination of Stereotactic Body Radiotherapy and Pembrolizumab in Metastatic NSCLC

Background:
Immune checkpoint inhibitors are taking on a growing role in the treatment of patients with metastatic NSCLC. Pre-clinical evidence suggests that radiotherapy may increase the frequency, or enhance the strength of the host anti-cancer immune response. We report the preliminary results of an ongoing phase I/II trial combining stereotactic body radiotherapy (SBRT) and the anti-PD-1 antibody pembrolizumab in patients with metastatic NSCLC.

Methods:
Eligible patients are those with metastatic NSCLC who have received no prior immune-directed therapy, and have at least 2 sites of measurable disease as per RECIST 1.1. PD-L1 expression is not required for study entry. All patients are treated with pembrolizumab at 200 mg every 3 weeks until development of progressive disease by immune-related RECIST criteria (irPD). After irPD, patients receive SBRT to a single site of disease and continue pembrolizumab. The primary endpoint is safety and tolerability. Secondary endpoints include the pre- and post-SBRT overall response rate.

Results:
27 patients with advanced NSCLC have enrolled and started trial therapy. The overall response rate (irPR and irCR) to the initial course of pembrolizumab is 35%. To date, 13 patients have had irPD: 5 were not eligible for SBRT and stopped study treatment (2 developed new brain metastases, 3 had decline in PS), and 8 patients received SBRT to a single site of disease (6 thoracic, 1 adrenal, 1 vertebral) and continued pembrolizumab. 5 of these patients are evaluable for post-SBRT response: 1 patient had confirmed irPD, 4 have irSD and continue pembrolizumab post-SBRT at a median duration of 3 months (range 1 to 5 months). 2 of the 4 patients with irSD have had > 20% decrease in the sum of diameters of their unirradiated targets, since SBRT. Regarding adverse events, in the pre-SBRT phase 6 of 27 patients (22%) developed grade 3 treatment-related toxicity (2 colitis, hepatitis, pneumonitis, hypothyroidism, conjunctivitis). In the SBRT and post-SBRT phases, there have been no grade 2 or greater treatment-related events.

Conclusion:
The addition of SBRT to pembrolizumab has not resulted in an increase in treatment-related toxicity. Several patients who had serially confirmed irPD to pembrolizumab monotherapy underwent SBRT and now have irSD, with some evidence of tumor regression. Updated results will be presented.


combination of erlotinib and atezolizumab有更稳定的实验效果

Safety, Clinical Activity and Biomarker Results from a Phase Ib Study of Erlotinib plus Atezolizumab in Advanced NSCLC

Background:
Targeted therapy with erlotinib is effective in reducing tumor burden in EGFR-mutant non-small cell lung cancer (NSCLC). However, resistance to therapy develops almost universally. Atezolizumab, an engineered mAb that inhibits binding of PD-L1 to its receptors, PD-1 and B7.1, has demonstrated promising monotherapy activity in NSCLC. Given that atezolizumab may enhance and perpetuate anti-tumor immunity, we hypothesized that combining atezolizumab with erlotinib may improve both clinical response and durability in EGFR-mutant NSCLC.

Methods:
This Phase Ib study consisted of a safety-evaluation stage in patients with NSCLC regardless of EGFR status followed by an expansion stage in TKI-naïve patients with tumors harboring activating EGFR mutations. Patients were enrolled regardless of PD-L1 status. After a 7-day run-in with 150mg erlotinib PO QD alone, patients received 150mg erlotinib PO QD and 1200mg atezolizumab IV q3w. To evaluate immune biology, biopsies were obtained in expansion-stage patients pre-treatment, after erlotinib run-in, at weeks 4-6, and at progression. The primary objective was to evaluate the safety and tolerability of the combination. Secondary objectives included evaluation of the clinical activity per RECIST v1.1. Data cutoff, 11 April 2016.

Results:
Twenty-eight patients (safety stage, n = 8; expansion stage, n = 20) who received ≥ 1 dose of erlotinib or atezolizumab were considered safety evaluable. Median age was 61y (range, 47-84); median survival follow-up was 11.2mo (range, 0.8-24.2). The incidence of either treatment-related G3-4 AEs was 39% and for serious AEs, 50%. The most common atezolizumab-related G3-4 AEs were pyrexia and increased ALT. No pneumonitis was reported. No treatment-related G5 AEs occurred. Five patients discontinued atezolizumab due to treatment-emergent AEs. No DLTs were observed. In the expansion-stage population, ORR was 75% (95% CI, 51-91). Disease control rate (CR + PR + SD ≥ 24 weeks) was 90% (95% CI, 68-99), median PFS was 11.3mo (95% CI, 8.4-NE) and median DOR was 9.7mo (range, 4.2-11.7). Increases in intratumoral CD8+ T cells post-erlotinib run-in were observed in 8/13 evaluable paired biopsies. Higher intratumoral CD8+ T-cell prevalence and immune gene expression signatures at baseline were associated with improved PFS.

Conclusion:
The combination of full dose erlotinib plus atezolizumab demonstrated a manageable safety profile. While response rates and median PFS for combination treatment appear similar to those observed with erlotinib monotherapy, the addition of atezolizumab to erlotinib may lead to more durable clinical responses in some patients. Additional follow-up is required to evaluate the full potential of this combination treatment.

当和免疫治疗联合,比如免疫检查点阻断,局部的放射可以有效的使患者正在照射的肿瘤有免疫性,改变肿瘤成为一个个性化的situ vaccine,当成功了,这获得的免疫反应加强注射在被放射的肿瘤和其相邻区域中。(可以与注射了疫苗后获得的对病毒性和细菌性感染的抗拒相比较)。

Inappropriate activation of Hh pathway signaling and uncontrolled cellular proliferation, as is observed in a variety of cancers, may be associated with mutations in the Hh-ligand cell surface receptor Smo.)

I noticed, on the pages you mention, in particular the research (several abstracts) on the hedgehog pathway done by this research group in Naples. Here is one of the abstracts (abstract 8P):

"Efficacy of osimertinib in combination with Hedgehog pathway inhibitors in reverting T790M-mediated resistence

E. Martinelli, F. Ciardiello, F. Morgillo

Studi di Napoli (AOU-SUN), Naples, Italy

Background: We have previously found that Hedgehog pathway plays an important
role in mediating resistance to first, second and third generation EGFR tyrosine kinase
inhibitors (EGFR-TKIs), suggesting new potential strategies of combination of novel
generation EGFR-TKIs with Hedgehog inhibitors to prevent the occurrence of
resistance in T790M + tumors.

Methods: H1975-AFAR and –OSIR NSCLC cell lines, harboring both the EGFR
activating (L858R) and the resistant (T790M) mutations at baseline, were developed in
vivo by continuos treatment with afatinib and osimertinib respectively. Both cell lines
presented also the SMO V404M mutation after acquisition of resistance. These cell
lines were used to test the efficacy of osimertinib or afatinib in combination with the
selective SMO inhibitor, LDE225.

Results: Treatment with each EGFR-TKIs in combination with LDE225 resulted in a
significant inhibition of cell proliferation and a strong induction of apoptosis as compared
to single agent treatment. Additionally, combined treatment significantly decreased the
invasive and migratory abilities of resistant cells. The combination of osimertinib and
LDE225 appeared to be the most effective in reverting resistance to EGFR-TKIs. Combined
treatment caused regression of tumor growth in vivo in nude mice.

Conclusions: Our study further support the role of Hedgehog pathway activation as an
important mediator of resistance to EGFR targeting drugs, also in the T790M scenario.
In addition, it demonstrates that addition of a hedgehog inhibitor to an EGFR-TKI in
tumors, which had developed resistance to third generation inhibitors, provides
meaningful responses."

TKI皮疹用口头或局部治疗(Minocycline二甲胺四环素,Doxycycline多西环素都是100mg,克林霉素—局部的),或一个局部的类固醇cream(Clobetasol Propionate 0.05%等)。TKI皮疹不是痤疮,用痤疮产品会加重情况?

一些皮疹在身体上,并在皮肤的皱纹和折痕里可能会变成真菌感染,他们治疗的越快越好。

athlete’s foot 和 jock itch
Use OTC products for athlete’s foot and jock itch. Expose to air 2 – 3 time a day. Use fungal powder to avoid future outbreaks.

干皮肤(大部分TKI)

O’Keefe’s Working Hands, Udderly Smooth , CeraVe, Eucerin to name a few. Argan or coconut oil are effective, too.(也许需要一些实验才能找到有效用比较高的。)

Kenalog (script)对于非常痒的rash。问医生其他的steroid creams and lotions。可以看皮肤科医生,只要看对TKI熟悉的医生就可以。


头部
掉头发、头发会改变质地等,长的很慢。

面部毛发
轻微的可以用OTC

头皮皮疹或结痂
Zinc Shampoo DHS 香波,(script and available OTC), Ciclopirox 1% Shampoo (script), Capex Shampoo (script) Olux Foam Shampoo (script). Note that sun, heat and perspiration can make the scalp rash worse.


香波护发素的使用
避免有酒精含在里面?

眼部
Tarceva users should beware of wiry, rogue eyelashes that bend(弯曲) and wind up hitting your eyeball and infected or ingrown lashes. Contact your ophthalmologist.(眼科的医生)

刺激/干燥
温暖的敷布对于滑腻的、硬的早晨的眼睛。
在刺激持续几天之前去找眼科医生,TKI有角膜炎的副作用。
白内障更为普遍,在TKI使用者中,一段时间去看一次眼科医生。

鼻子和嗓子
气短,告诉医生,TKI有小风险的间质性肺病。

流鼻水
Claritin Allergy Relief or Flonase for drippy nose.
cotton buds smearing up the nose(乳头霜和棉花芽涂抹鼻子)

-------------------------------------------------------------------------------------------
bleeding nose
mothers nipple cream on cotton buds smearing up the nose




鼻孔溃疡(sore)
Neosporin, Ayr (OTC gel) or Futacason (script) on a Q-tip inside nostrils.

嘴部(溃疡或干燥)
Magic Swizzle Sticks from Pharmacy. Mix equal parts of Peroxide and Water and gargle daily. Magic Mouthwash, Stomatitites Cocktail, Vanderbilt Formula (scripts).

Diflucan (script) for Oral Thrush (which is a whitish fungal infection coating on your tongue). Do call the onc for this one!
Biotene toothpaste and mouth rinse (both OTC) for dry mouth. Toothpaste is very gentle for mouths with sores.
Tarceva users in particular find that the taste of certain foods (spicy or acidic) will change. This should decrease over time.
小苏打可以当柔软的牙刷,小苏打和水混合(口腔清洗)


胃酸
看医生。Tarceva in particular works with the acid in your stomach. While relief is important, it shouldn’t interfere with the Tarceva

便秘
番泻叶天然泻药,Miralax, Colace and Fiber Gummies.

腹泻
易蒙停和益菌(Probiotics),止泻宁,加一些通便的可以有帮助(美达施,psyllium husk fiber等。)??Use the BRATT (bananas, rice, applesauce, toast and tea) to help calm things down.

UPET STOMACH – ginger tea, peppermint tea, coke syrup (pharmacy OTC), Carafate (script).胃不舒服胃痛?

胃口
当有胃口时吃含卡洛里尽量多的食物。

腿痛性痉挛
医生应当做一个CBC检查身体里元素含量水平。

手指和脚趾
保持脚干净干燥、保持指甲是修正过的、穿舒适宽松的鞋。

如果手指或脚趾的角质层看起来发炎或感染了,找足病医生,有可能是甲沟炎并且感染也许会变得严重。向内生长的脚趾甲也是常见的副作用,告诉足病医生?
Vaseline, Amonium Lactate 12% for cracked heels and feet. Epsom Salt soaks are helpful, too.

清理的时候用橡胶手套,一些需要注意的
Newskin, Nexcare or other waterproof bandages for split fingers and heels.
Desitin (yep, diaper rash cream) applied thinly to fingertips and a bit thicker other places.
Super glue (medical grade) for splits, too.

Moisturize、睡觉的时候带上棉手套、袜子。

如果感受到副作用加重或其他的副作用,找医生,在用别的药物移除这些副作用之前也要找医生,让你知道是什么副作用,并立刻做出应对。

https://www.inspire.com/groups/a ... -lung-cancer-surviv ors/discussion/tarceva-side-effect-busters-5/

Eliminate or cut down on potassium rich foods like bananas, spinach, tomatoes, chocolate, fresh salmon, etc.
Dexamethsone 0.5mg/5ml mouthwash, it is a preventative unlike magic mouthwash that is used after sores have developed.

关于吃药饭前饭后

对于脚的部分
Epson Salts A & D ointment (found in baby department) mixed with vitamin D oil to feet
polysporin, tea tree oil, epsom salts, soaking
冰袋管用吗?
soaked nail beds in water and vinegar twice a day...used exelderm and Mupirocin有很不错的帮助
used liquid bandages to ease the pain in fingers. Next started with a fungal infection in big toes. Now have Paronychia. You need a good antibiotic and need to soak your hands or effected feet in hot water ( Salted) to draw out inflammation. Depending on how infected it will need to be drained.
Fluoxycillian
甲沟炎
Bactrim效果很好过
关于指尖
一天浸透3-4次每次十分钟的指尖在有Epsom salts and a bit of coconut oil thrown in. coconut oil是一个自然的方式来治疗手指感染。(有一天内状况好了不少的)
put neosporin on the splits, slip on the cots, apply argon oil to the rest of my uncovered fingers & my hands
关于流鼻水
I have a constantly runny nose and was getting sores.minstarted using tissues infused with lotion (puffs and Kleenex both make them) and the sores no longer form.
头皮
Scalpicin药物的名称

穿棉的舒适的衣服

对于nimples需要保湿

皮疹
Gold Bond powder对皮疹很有效?减少发痒?一直保湿也很重要

驱动基因一般只有一个,如果需要选择新药了,仔细检查molecular testing的结果,要做biopsy和基因组面板(genomic panel)这两样。

要用PD-1/PD-L1抑制剂必须经历过化疗。

FDA也推荐了pd1/pd-l1抑制剂给squamous cell carcinoma type lung cancer类型患者。

关于脑转的治疗
显著提高的脑转PFS在EGFR TKI的治疗下:
https://www.inspire.com/groups/a ... -fight-is-still-on/

FDA正在加速批准Keytruda和培美曲塞、卡铂联用作为一线(frontline)治疗对于转移性的、进展性的非鳞NSCLC患者,无视PD-L1的表达。
http://www.curetoday.com/article ... %20story%20%5Cu00BB

FDA批准Portrazza用于鳞癌。

ROS1积极患者可以用crizotinib作为一线用药。
https://www.inspire.com/groups/a ... arch-lcam-and-hope/

Ceritinib比起克唑替尼使用限制要多一些。
Crizotinib不保护大脑?

Crizotinib特别的耐受?被用于一线alk+的进展的nsclc.

一个四期腺癌with all mutation 用Crizotinib 稳定了7个月。

曲美替尼,应对BRAF突变的靶向药。

NK细胞靶向。

免疫治疗与靶向药联用:

埃克替尼(凯美纳)是属于第一代针对EGFR靶点的国产靶向药物,与国外的易瑞沙和特罗凯属于相同药物。目前国际上已经批准的针对EGFR靶点二代的药物是阿法替尼、三代药物是Tagrisso(AZD9291);针对ALK的第一代药物是克唑替尼(赛可瑞),国际上已经有色瑞替尼和、阿雷替尼等;针对VEGF靶点的安维汀(贝伐珠单抗);另外还有一种很广谱的抗肿瘤药物,例如PD-1/PD-L1的免疫药物Opdivo,Keytruda和Tecentriq等。

9291+特罗凯,隔天184?

9291+280/克都可以考虑到CMET,而且光这个靶点,280/克的剂量由于副作用相对184低,剂量上可以更大

米哚妥林,c797s复合耐药突变。
西妥昔单抗+EAI045联用,西妥昔单抗单用对于仍有t790m突变的耐药患者并产生了c797s的部分有效(部分指?)

1、        体内仍然有不少T790m突变,9291 用60mg/d的剂量不足,这种情况就要考虑继续加量,60mg的量并不算大,如果副作用不大,可以考虑先加量到80mg;
2、体内有T790m突变的同时,仍然有EGFR突变存在,虽然9291对EGFR18、19、21也有作用,但是它的效力对比应该不会超过易、特、2992,或者60mg的9291 抑制不住EGFR突变,这种情况可以考虑联合易、特、(或者2992)曾经哪个有效果;
3、9291联合下游通路用药BKM120,BKM120不光是有PI3K突变,也是下游主要通路,肺腺癌病人中PI3K的突变率是2%,扩增率是6-19%;EGFR TKI联合BKM120可以克服HGF过表达导致的EGFR耐药问题,对于T790M或者cMet扩增导致的EGFR耐药病人,PI3K/Akt信号通路上调,EGFR TKI联合BKM120有一定效果。
4、体内T790m突变被清扫的差不多了,9291失去了作用的受体,完全耐药,换VEGFR靶点的阿西替尼、或者依托泊苷联合BKM120.
相关:http://www.yuaigongwu.com/thread-28922-1-1.html
5、如果有骨转或者CMET扩增的话,也可以考虑联合CMET药INC280、XL184、或则克唑替尼。
6、单药化疗;
2、        采用299804每天+9291隔天100mg
3、        盲试首先9291+易(或特),因较多为C797S突变。

299804 作用于HER-1/EGFR、HER-2、及HER-4。

Afatinib被推荐给进展性、转移性的EGF患者。对于EGFR mutation Del19有联用效果,L858R有小部分效果。

没突变考虑pd-1。

icotinib (凯美纳)对于脑转的治疗效果不错:
https://www.inspire.com/groups/a ... till-on/?ga=freshen

EGFR抑制剂有着更好的brain penetration (渗透)

erlotinib被认为有更好的效果对于脑部比起gefitinib

afatinib和osimertinib对于脑部效果比erlotinib好

Bevacizumab 与osimertinib 联合。

Dasatinib 对glioblastoma(exing胶质瘤)效果不错尤其是与afatinib和bevacizumab联用。

cetuximab, necitumumab (Portrazza) or bevacizumab跨越BBB并不容易,谨慎对待dasatinib for glioblastoma的实验结果。the BBB does not act the same way for glioblastoma and small brain metastases originating from NSCLC

艾乐替尼(alectinib)第二代ALK抑制剂,对脑转好像效果不错。

Pembro有过效果不错的例子。

osimertinib 交替卡铂+培美进行-对脑转很有效。

osimertinib 同时连续不断化疗。

Initial data from the ¬TATTON trial has found that osimertinib may be safely combined with a MET inhibitor (savolitinib) or a MEK inhibitor (selumetinib)。

Triple mutant cell lines 可能对哪代药都不敏感。

有两种药看起来对Triple mutant cell lines有效。(CUDC 1  0  1 和米哚妥林)
http://www.abstractsonline.com/pp8/#!/4292/presentation/5746

http://www.abstractsonline.com/p ... tions/osimertinib/1这个网址要通过insp进

osimertinib 和 crizotinib联用。

TMB与pd-1用药有关系。(mutational burden越高,免疫治疗有效的可能性越高)

对TKI治疗耐药,考虑下这个:
https://lungcancernewstoday.com/ ... 078ccd72b9-71328401

Tagrisso + Pemetrex

没有ALK ROS1突变不用克唑?
       
BRAF突变in addition EGFR Exon 20  selumetinib ,如果联用的话用dabrafenib 而不是azd2014。

单克隆抗体类:bevacizumab (Avastin) or ramucirimab (Cyramza)

ramucirimab 比bevacizumab副作用小

TKIs targeting VEGF-R are better than monoclonal antibodies.

TKI抑制VGFR:sorafenib, sunitinib, axitinib or apatinib.


2992对肺腺癌效果大。


gefitinib and afatinib 可以用于c797s double突变,Osimertinib 用于t790m double突变

关于brigatinib的信息:
http://www.nature.com/articles/ncomms14768?proof=true#results

brigatinib+ Osimertinib

brigatinib和西妥昔单抗联用比较好

除了对c797s之外,还可以考虑T790M loss 和 bypass pathway activation using existing treatment modalities, for example, turning back to first-generation EGFR–TKIs or combination therapy.

brigatinib和西妥昔单抗联用没有toxicity?

B+9291

Brigatinib和西妥昔单抗联用 IC50要小很多。

靶向药副作用比较也要考虑

Crizotinib打击三个靶点,副作用强有关于xiongshui 和食道的问题

如果考虑c met 的话 280与Osimertinib联用优于Crizotinib与Osimertinib联用

http://www.yuaigongwu.com/thread-29574-1-1.html   咨询

Lapatinib or Neratinib也许会是好的 TKI 在 C797S突变之后,因为占据atp site ?

爱必妥联用也许有重要性?

克唑替尼控制脑转移效果很有限,脑脊液浓度为血药浓度的0.26%。alectinib脑脊液浓度达到60%以上。


sclc的标准治疗是化疗。

T regulatory cells高了不好,和TILs有关系?

头盖放射延迟并发症:
https://www.uptodate.com/content ... cranial-irradiation

PD-L1 inhibitors such as Tecentriq (atezolizumab) or durvalumab的有效性,很大部分和pd-l1表达水平无关。

proton radiation therapy (质子放射治疗)容易产生高发生率的放射性坏死。
http://www.ajnr.org/content/early/2015/07/02/ajnr.A4333

Proton治疗最大程度的减小了放射超过肿瘤的范围,对于之前接受过传统放疗的部位很合适使用。
https://www.ncbi.nlm.nih.gov/pub ... with+scanned+charge d+particle+beams+Jensen

脑部治疗重复使用Gamma Knife可以?

Val-083      cells with p53, EGFR, or KRAS mutations were highly sensitive
新批准的胶质瘤药 对肺癌和其他癌症有一定效果
