酪氨酸激酶抑制剂
  • 文章类型: Journal Article
    抗癌全身性治疗包括一组复杂且不断增长的药物。一些已经出现的具有新作用机制的新药很难适应经典化疗的组,荷尔蒙,酪氨酸激酶抑制剂,和单克隆抗体。我们提出了基于两个层面信息的分类:行动地点和行动机制。关于前者,药物可以在肿瘤细胞中发挥作用,肿瘤脉管系统,免疫系统,或内分泌系统。作用机理是指分子靶标。
    Anticancer systemic therapy comprises a complex and growing group of drugs. Some of the new agents with novel mechanisms of action that have appeared are difficult to fit in the groups of classical chemotherapy, hormones, tyrosine-kinase inhibitors, and monoclonal antibodies. We propose a classification based on two levels of information: the site of action and the mechanism of action. Regarding the former, drugs can exert their action in the tumor cell, the tumor vasculature, the immune system, or the endocrine system. The mechanism of action refers to the molecular target.

    背景:免疫检查点抑制剂(ICIs)的出现彻底改变了转移性肾细胞癌(mRCC)的治疗前景。然而,靶向血管内皮生长因子(VEGF)轴的酪氨酸激酶抑制剂(TKIs)仍然起着关键作用。本研究的目的是探索综合血液评分的预后表现,基于血红蛋白(Hb)浓度,平均红细胞体积(MCV),和红细胞分布宽度(RDW),抗VEGFTKIs治疗的mRCC患者。主要终点是Hb,MCV,和RDW的无进展生存期(PFS)和总生存期(OS)。
    方法:我们的多中心回顾性观察性研究纳入了2012年1月至2020年12月在9个意大利中心接受帕唑帕尼或卡博替尼治疗的mRCC患者。临床记录和实验室数据,包括Hb水平,MCV,和RDW,在基线时收集。进行描述性统计以及单变量和多变量分析。
    结果:我们招募了301例mRCC患者,其中179例(59%)接受了帕唑帕尼治疗,和122(41%)卡博替尼。我们认为基线Hb≥12g/dL,MCV>87fL,RDW≤16%是良好的预后因素;因此,开发一个能够划分4个不同类别的多参数分数。良好预后因素的数量与显著延长的PFS和OS相关(两者p<0.001)。因此,我们通过将病例分为两组(2-3和0-1,良好因子),制定了基于红细胞的评分.对PFS和OS的影响甚至更显著(中位数PFS(mPFS):16.3比7.9个月;中位数OS(mOS):33.7比14.1个月),不管是什么TKI特工.当受到单变量和多变量分析的挑战时,就OS而言,血液评分保持其较高的预后意义(OS的多变量分析HR:0.53,95%CI0.39-0.75;p<0.001),而对PFS的影响则具有临界意义。
    结论:我们的分析证明了基于易于利用的血液参数的多参数评分的预后作用,如Hb浓度,MCV,和RDW。基于红细胞的评分可能是HIF-1α途径和VEGF轴上调的基础,从而确定可能受益于TKI治疗的选定人群。
    The advent of immune checkpoint inhibitors (ICIs) has revolutionized the metastatic renal cell carcinoma (mRCC) therapeutic landscape. Nevertheless, tyrosine-kinase inhibitors (TKIs) targeting the vascular endothelial growth factor (VEGF) axis still play a key role. The aim of the present study was to explore the prognostic performance of an integrated blood score, based on hemoglobin (Hb) concentration, mean corpuscular volume (MCV), and red cell distribution width (RDW), in mRCC patients treated with anti-VEGF TKIs. The primary endpoint was to correlate Hb, MCV, and RDW with progression-free survival (PFS) and overall survival (OS).
    Our multicenter retrospective observational study involved mRCC patients treated with pazopanib or cabozantinib from January 2012 to December 2020 in nine Italian centers. Clinical records and laboratory data, including Hb levels, MCV, and RDW, were collected at baseline. Descriptive statistics and univariate and multivariate analyses were performed.
    We enrolled 301 mRCC patients of which 179 (59%) underwent pazopanib, and 122 (41%) cabozantinib. We considered baseline Hb ≥12 g/dL, MCV >87 fL, and RDW ≤16% as good prognostic factors; hence, developing a multiparametric score capable of delineating 4 different categories. The number of good prognostic factors was associated with significantly longer PFS and OS (p < 0.001 for both). Therefore, we developed a red blood cell-based score by stratifying cases into two groups (2-3 versus 0-1, good factors). The impact on PFS and OS was even more striking (median PFS (mPFS): 16.3 vs 7.9 months; median OS (mOS): 33.7 vs 14.1 months)), regardless of the TKI agent. When challenged with univariate and multivariate analysis, the blood score maintained its high prognostic significance in terms of OS (multivariate analysis HR for OS: 0.53, 95% CI 0.39-0.75; p < 0.001, respectively), while the impact on PFS resulted in borderline significance.
    Our analyses demonstrate the prognostic role of a multiparametric score based on easily exploitable blood parameters, such as Hb concentration, MCV, and RDW. The red blood cell-based score may underlie the upregulation of the HIF-1α pathway and VEGF axis, thereby identifying a selected population who is likely to benefit from TKI therapy.

    背景:转移性肾细胞癌(mRCC)患者的全身治疗在过去几年中有所改善,随着新的基于免疫疗法的联合疗法的出现,作为一线治疗的标准治疗选择。然而,特别是在IMDC标准的高危患者中,酪氨酸激酶抑制剂(TKI)可能仍然是一些患者的选择。我们回顾了TKI作为mRCC患者一线治疗的经验,试图确定可能仍受益于该策略的患者亚组。
    方法:所有接受一线TKI治疗的mRCC患者,和充分的后续行动,拉巴斯大学医院(马德里,西班牙)在2007年至2020年之间进行了分析。在临床试验中治疗的患者被排除在该分析之外。
    结果:共纳入90例接受一线TKI治疗的患者。关于IMDC标准,33例患者(36.7%)为好风险,41例(45.5%)中危,16例患者(17.8%)风险较差。中位随访时间为49个月,中位总生存期(OS)为好,中间,低危患者分别为54、24和16个月(p=0.004).当将中等风险分为具有1或2个危险因素的患者时,OS的差异也具有统计学意义:具有1个危险因素的患者的中位OS为33个月,而有2个危险因素的患者的中位OS为16个月,与低风险患者相同(p=0.003)。在多变量分析中,试图找出哪些IMDC因素在患者的预后中具有更显著的权重,ECOG和血红蛋白水平本身均与OS显著相关.
    结论:在我们组的患者中,根据IMDC标准,具有1或2个危险因素的中危患者的生存结局不同.这些可以帮助选择可能从TKI一线治疗中受益的患者,特别是在难以获得新疗法的环境中,例如基于免疫疗法的组合。
    BACKGROUND: Systemic therapy of patients with metastatic renal cell carcinoma (mRCC) has improved in the past years, with the advent of new immunotherapy-based combinations as a standard treatment option for first-line therapy. Nevertheless, particularly in good-risk patients by IMDC criteria, tyrosine-kinase inhibitors (TKI) may remain as an option for some patients. We reviewed our experience with TKI as first-line therapy for mRCC patients, trying to identify subgroups of patients that may still benefit from this strategy.
    METHODS: All patients with mRCC treated with first-line TKI, and adequate follow-up, in University Hospital La Paz (Madrid, Spain) between 2007 and 2020 were analyzed. Patients treated inside a clinical trial were excluded from this analysis.
    RESULTS: A total of 90 patients treated with first-line TKI were included. Regarding IMDC criteria, 33 patients (36.7%) were good-risk, 41 patients (45.5%) intermediate-risk, and 16 patients (17.8%) poor-risk. With a median follow-up of 49 months, the median overall survival (OS) for good, intermediate, and poor-risk patients was 54, 24, and 16 months (p = 0.004). When intermediate-risk was divided into patients with 1 or 2 risk factors, differences in OS were also statistically significant: patients with 1 risk factor had a median OS of 33 months, while patients with 2 risk factors had a median OS of 16 months, the same as poor-risk patients (p = 0.003). In the multivariate analysis, trying to find out which of the IMDC factors had a more remarkable weight in the prognosis of the patients, both ECOG and hemoglobin levels by themselves were significantly associated with OS.
    CONCLUSIONS: In our group of patients, survival outcomes were different among patients with intermediate-risk with 1 or 2 risk factors by IMDC criteria. These could help select patients that may benefit from first-line treatment with a TKI, particularly in settings with difficult access to novel therapies, such as immunotherapy-based combinations.

    系统性肥大细胞增多症(SM)是一种复杂且异质性的疾病,以肥大细胞在一个或多个器官中的克隆积累为特征。2022年,世界卫生组织(WHO)和国际共识分类(ICC)都修改了SM的诊断和分类标准。此外,新的临床和分子变量的识别改善了预后工具,并导致越来越多的个体化治疗策略.
    本文的目的是介绍国际共识分类在SM诊断标准中引入的更新。此外,我们报告了来自非晚期和晚期疾病患者的最重要临床试验的最新数据,包括elenestinib和bezuclastinib。
    SM的诊断和分类已经发展了多年。最新的WHO和ICC分类改进了SM诊断工作,为临床医生提供清晰、简化的诊断方案。新批准的靶向疗法,如midostaurin和avapritinib改变了晚期患者的治疗模式,在临床试验中实际研究的下一代抑制剂有望在未来出现。
    Systemic mastocytosis (SM) is a complex and heterogeneous disease, characterized by the clonal accumulation of mast cells in one or more organs. In 2022 both the World Health Organization (WHO) and the International Consensus Classification (ICC) modified the diagnostic and classification criteria of SM. Moreover, the identification of new clinical and molecular variables has improved prognostic tools and led to increasingly individualized therapeutic strategies.
    The aim of this review is to present the updates introduced by the International Consensus Classification in diagnostic criteria of SM. In addition, we report the latest data available from the most important clinical trials in patients both with non-advanced and advanced disease, including elenestinib and bezuclastinib.
    Diagnosis and classification of SM has evolved over years. The most recent WHO and ICC classification improved SM diagnostic work-up, providing clinicians with a clear and simplified diagnostic scheme. New approved targeted therapies such as midostaurin and avapritinib modified the treatment paradigm in patients in advanced stage, and next-generation inhibitors actually investigated in clinical trials are expected in the next future.

    未经授权:尽管在过去20-30年中进行了广泛的研究,软组织肉瘤(STS)的治疗方法基本上保持不变,以蒽环类为基础的化疗仍是治疗晚期或转移性STS的首选。
    UNASSIGNED:这篇综述的重点是新批准的STS药物和当前的研究方向,包括最近的STS患者的晚期试验结果。我们涵盖了几种不同的组织学亚型,我们讨论过继性细胞转移(ACT)治疗滑膜和粘液样/圆形细胞(高度粘液样)脂肪肉瘤的作用,迄今为止最有前途的治疗发展领域之一。我们搜索了clinicaltrials.gov和pubmed。ncbi.nih.gov,以及最近一年美国临床肿瘤学会(ASCO)年度会议的会议记录,欧洲医学肿瘤学会(ESMO),和结缔组织肿瘤学会(CTOS)。
    未经批准:肿瘤免疫药物(IOs)在某些STS亚型中显示出希望,但人们认识到PD-1/PD-L1轴抑制本身是不够的。需要根据STS不同亚型的分子分类进行更好的试验分层,更多的证据表明,在这种异质性和侵袭性的肿瘤组中,“一刀切”的治疗不再是可持续的。
    UNASSIGNED: Despite extensive research undertaken in the past 20-30 years, the treatment for soft tissue sarcoma (STS) has remained largely the same, with anthracycline-based chemotherapy remaining the first choice for treating advanced or metastatic STS.
    UNASSIGNED: This review focuses on newly approved drugs for STS and current research directions, including recent results of late-phase trials in patients with STS. We cover several different histological subtypes, and we discuss the role of adoptive cell transfer (ACT) therapies for the treatment of synovial and myxoid/round cell (high-grade myxoid) liposarcoma, one of the most promising areas of treatment development to date. We searched clinicaltrials.gov and pubmed.ncbi.nih.gov, as well as recent year proceedings from the annual conferences of the American Society of Clinical Oncology (ASCO), European Society for Medical Oncology (ESMO), and Connective Tissue Oncology Society (CTOS).
    UNASSIGNED: Immune-oncology drugs (IOs) show promise in certain subtypes of STS, but it is recognized that PD-1/PD-L1 axis inhibition is not enough on its own. Better trial stratifications based on the molecular categorization of different subtypes of STS are needed, and more evidence suggests that \'one size fits all\' treatment is no longer sustainable in this heterogeneous and aggressive group of tumors.

    间变性甲状腺癌(ATC)是人类已知的最致命的疾病之一,中位生存期为5个月。美国甲状腺协会(ATA)最近发布了治疗这种可怕的甲状腺恶性肿瘤的指南。
    这篇综述介绍了这种具有挑战性的疾病的当前治疗前景。我们还介绍了过去五年发表的试验结果,并总结了目前正在进行的临床试验。
    最近改善这些肿瘤预后的尝试正在走向个性化医疗,根据个体肿瘤的特定遗传特征做出治疗决定。dabrafenib和trametinib对具有BRAFV600E突变的ATC的阳性结果提供了有用的治疗选择。对于其他的遗传基因,有不同的药物可供选择,可用于个性化治疗,可能使用药物组合。药物的组合作用于不同的分子途径并在不同的区域实现抑制。有了新的靶向治疗,随着生活质量的改善,平均生存期显著改善,局部疾病进展或气道受损导致死亡的可能性较小.不幸的是,就生存而言,结果仍然很差。
    Anaplastic thyroid cancer (ATC) is one of the most lethal diseases known to humans with a median survival of 5 months. The American Thyroid Association (ATA) recently published guidelines for the treatment of this dreadful thyroid malignancy.
    This review presents the current therapeutic landscape of this challenging disease. We also present the results from trials published over the last five years and summarize currently active clinical trials.
    Recent attempts to improve the prognosis of these tumors are moving toward personalized medicine, basing the treatment decision on the specific genetic profile of the individual tumor. The positive results of dabrafenib and trametinib for ATC harboring the BRAF V600E mutation have provided a useful treatment option. For the other genetic profiles, different drugs are available and can be used to individualize the treatment, likely using drug combinations. Combinations of drugs act on different molecular pathways and achieve inhibition at separate areas. With new targeted therapies, average survival has improved considerably and death from local disease progression or airway compromise is less likely with improvement in quality of life. Unfortunately, the results remain poor in terms of survival.

    急性淋巴细胞白血病(ALL)是一种罕见的血液恶性肿瘤,其特征是过早的淋巴母细胞增殖和积累。根据风险因素,在过去的几十年中,急性淋巴细胞白血病的生存率显著提高.在过去的几年里,可测量的残留病(MRD)评估已经发展成为预后和复发风险最敏感的指标之一.出于这个原因,可测量的残留病检测和监测计数作为急性淋巴细胞白血病患者的标准评估。同种异体干细胞移植仍然是具有高风险和最高风险的患者以及复发或难治性患者的推荐治疗选择。对急性淋巴细胞白血病的病理机制和异质性的日益了解导致了一些新的治疗机会的发展,例如酪氨酸激酶抑制剂。基于抗体的疗法和CAR-T细胞,旨在改善临床结果。此外,对ALL的疾病认识方面的重大进展导致了对不同亚组的识别和更好的疾病分层.尽管不断开发新的治疗靶点,急性淋巴细胞白血病仍然是一种具有挑战性和危及生命的疾病.为了改善成人急性淋巴细胞白血病治疗的历史上不令人满意的结果,最近已经开始了许多临床试验,以确定成人急性淋巴细胞白血病的新型和旧药物的最佳组合方案。
    Acute lymphoblastic leukemia (ALL) is a rare hematological malignancy characterized by proliferation and accumulation of premature lymphoid blasts. Depending on risk factors, the survival of acute lymphoblastic leukemia has significantly improved over the last decades. During the last years, measurable residual disease (MRD) assessment has evolved into one of the most sensitive markers for prognosis and risk of relapse. For this reason, measurable residual disease detection and monitoring count as standard evaluation in patients with acute lymphoblastic leukemia. Allogeneic stem cell transplantation is still the recommended treatment option for patients with high and highest risk profiles as well as for relapsed or refractory settings. The increased understanding of the pathomechanism and heterogeneity of acute lymphoblastic leukemia has led to the development of several novel therapeutic opportunities such as tyrosine-kinase inhibitors, antibody-based therapies and CAR-T cells with the aim of improving clinical outcomes. Furthermore, the major advances in disease understanding of ALL have led to the identification of different subgroups and better disease stratification. Even though novel therapy targets are constantly developed, acute lymphoblastic leukemia remains a challenging and life-threatening disease. To improve the historically unsatisfying result in therapy of adult acute lymphoblastic leukemia many clinical trials have recently been initiated to determine the optimum combination regimens of novel and old agents for adult acute lymphoblastic leukemia.

    所有乳腺癌(BC)中约有15-20%被定义为人类表皮生长因子受体2(HER2)阳性,基于HER2蛋白的过表达和/或ERBB2基因的扩增。这种改变导致疾病更具攻击性的行为,还可以预测对针对HER2的治疗的反应。的确,在过去的二十年中,已经开发并批准了几种抗HER2化合物,显著提高我们在早期治愈患者的能力,大大延长了他们在先进环境中的生存时间。然而,这一领域的最新发展有望进一步改善成果,通过改进既定的HER2靶向策略,以及对新颖策略的探索。特别是,新型抗体-药物偶联物的工程,具有较高的药物与抗体比率(DAR)和可切割接头,已经导致了一种高效药物的开发,即曲妥珠单抗deruxtecan,最近由美国食品和药物管理局(FDA)和欧洲药品管理局(EMA)批准用于治疗晚期HER2阳性(HER2+)BC,目前正在早期研究中。此外,新型酪氨酸激酶抑制剂图卡替尼最近被FDA和EMA批准,显示改善HER2+晚期BC患者的生存率,特别是那些脑转移的患者。免疫疗法也在HER2+亚型中进行研究,通过免疫检查点抑制,癌症疫苗和过继细胞疗法。总的来说,有望扩大有前景的抗HER2化合物的武器库,有望在未来几年显著改善早期和晚期HER2+BC的预后.此外,一些此类药物在更广泛的HER2低晚期BC患者中显示出令人鼓舞的活性,挑战当前的BC分类。如果确认,这种新的模式可能会将从HER2靶向治疗中获益的人群扩大到所有晚期BC患者的70%,导致当前治疗算法的革命,并可能重新定义HER2分类。
    About 15-20% of all breast cancers (BCs) are defined human epidermal growth factor receptor 2 (HER2)-positive, based on the overexpression of HER2 protein and/or amplification of ERBB2 gene. Such alterations lead to a more aggressive behavior of the disease, but also predict response to treatments targeting HER2. Indeed, several anti-HER2 compounds have been developed and approved in the last two decades, significantly improving our ability to cure patients in the early setting, and greatly extending their survival in the advanced setting. However, recent evolutions in this field promise to improve outcomes even further, through advancements in established HER2-targeting strategies, as well as the exploration of novel strategies. In particular, the engineering of new antibody-drug conjugates, with higher drug-to-antibody ratios (DARs) and cleavable linkers, has already led to the development of a highly effective drug, namely trastuzumab deruxtecan, recently approved by the Food and Drug Administration (FDA) and European Medicines Agency (EMA) for the treatment of advanced HER2-positive (HER2+) BC, and currently in study in the early setting. Moreover, the novel tyrosine kinase inhibitor tucatinib was recently approved by FDA and EMA, showing to improve survival of HER2+ advanced BC patients, particularly in those with brain metastasis. Immunotherapy is also being investigated in the HER2+ subtype, through immune-checkpoint inhibition, cancer vaccines and adoptive-cell therapies. Overall, the enlarging arsenal of promising anti-HER2 compounds is expected to deliver significant improvements in the prognosis of both early and advanced HER2+ BC in the years to come. Moreover, some of such agents are showing encouraging activity in the much wider population of HER2-low advanced BC patients, challenging current BC classifications. If confirmed, this new paradigm would potentially expand the population deriving benefit from HER2-targeted treatments to up to 70% of all advanced BC patients, leading to a revolution in current treatment algorithms, and possibly to a redefinition of HER2 classification.

    非小细胞肺癌(NSCLC)在全球范围内导致显著的死亡率。慢性肾功能衰竭患者患肺癌的风险增加。接受血液透析(HD)的慢性肾衰竭NSCLC患者通常表现不佳,化疗通常是禁忌的。口服表皮生长因子受体(EGFR)-酪氨酸激酶抑制剂(TKIs)是NSCLC患者的有效治疗剂。然而,EGFR-TKIs在接受HD的NSCLC中的获益和不良反应是已知的.目前尚无关于EGFR-TKIs对接受HD的NSCLC患者的影响的临床研究。我们回顾了之前所有关于EGFR-TKIs在接受HD的NSCLC患者中的病例报告。很难设计关于EGFR-TKIs对HD患者的影响的研究,这次审查非常重要。EGFR-TKIs在HD患者中耐受性良好。EGFR-TKIs的主要消除途径是通过肝脏代谢,肾脏消除较小。这些EGFR-TKIs对HD患者的推荐剂量和药代动力学与肾功能正常的患者相似。EGFR-TKIs的血浆蛋白结合非常高,并且没有必要在HD后调整剂量。总之,EGFR-TKIs在HD患者中有效且耐受性良好。
    Non-small-cell lung cancer (NSCLC) causes significant mortality worldwide. Patients with chronic renal failure have an increased risk of developing lung cancer. NSCLC Patients with chronic renal failure undergoing hemodialysis (HD) often exhibit poor performance, and chemotherapy is generally contraindicated. Oral epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are effective treatment agents for NSCLC patients. However, the benefits and adverse effects of EGFR-TKIs in NSCLC undergoing HD are known. There are no clinical studies on the effects of EGFR-TKIs on NSCLC patients undergoing HD. We reviewed all previous case reports about EGFR-TKIs in NSCLC patients undergoing HD. It is difficult to design studies about the effects of EGFR-TKIs in patients undergoing HD, and this review is quite important. EGFR-TKIs are well tolerated in patients undergoing HD. The main routes of elimination of EGFR-TKIs are metabolism via the liver, and renal elimination is minor. The recommended doses and pharmacokinetics of these EGFR-TKIs for patients undergoing HD are similar to those for patients with normal renal function. The plasma protein binding of EGFR-TKIs is very high, and it is not necessary to adjust the dose after HD. In conclusion, EGFR-TKIs are effective and well tolerated in patients undergoing HD.
