    早期可切除非小细胞肺癌(rNSCLC)的多学科治疗进展正以前所未有的速度出现。许多3期试验产生的结果使患者的预后变得更好,然而,这些发现还需要对患者的治疗轨迹进行重要修改,并重新组织护理路径.也许最值得注意的是,对这一患者人群进行多专科合作的需求从未如此大.这些迅速的进步不可避免地给我们留下了重要的知识空白,只有在几年内才能得到明确的答案。为此,IASLC委托了一个多元化的多学科国际专家小组来评估当前形势并提供诊断,分期,和rNSCLC患者的治疗建议,特别强调AJCC/UICCTNM第8版II期和III期疾病的患者。使用基于团队的方法,我们提出了19条建议,除一名成员外,所有成员都达成了85%以上的共识。开始了公开投票程序,它成功验证并为我们的建议提供了质的细微差别。重点包括:1)在多专业专家团队的共同临床决策推动下,多学科方法对rNSCLC患者进行评估的至关重要性;2)rNSCLC的生物标志物测试;3)对III期rNSCLC的新辅助化学免疫疗法的偏好;4)在前期手术,然后进行辅助治疗和新辅助/围手术期策略之间,对II期患者的最佳管理进行平衡;5)对NSCLC患者进行强有力的辅助治疗和EGFR敏感性治疗和我们的主要目标是为rNSCLC患者提供对生物学和资源的全球差异敏感的实用建议。并提供针对个性化患者需求的专家共识指导,目标,以及他们在癌症护理旅程中的偏好,因为这些领域是医生必须在缺乏明确数据的情况下做出日常临床决策的领域。随着rNSCLC治疗前景的扩大,这些建议将继续发展,并且在特定患者和疾病亚组中获得更多关于最佳治疗方法的知识。
    Advances in the multidisciplinary care of early-stage resectable non-small cell lung cancer (rNSCLC) are emerging at an unprecedented pace. Numerous phase 3 trials produced results that have transformed patient outcomes for the better, yet these findings also require important modifications to the patient treatment journey trajectory and re-organization of care pathways. Perhaps most notably, the need for multispecialty collaboration for this patient population has never been greater. These rapid advances have inevitably left us with important gaps in knowledge for which definitive answers will only become available in several years. To this end, the IASLC commissioned a diverse multidisciplinary international expert panel to evaluate the current landscape and provide diagnostic, staging, and therapeutic recommendations for patients with rNSCLC, with particular emphasis on patients with AJCC/UICC TNM 8th edition stage II and III disease. Using a team-based approach, we generated 19 recommendations, of which all but one achieved greater than 85% consensus amongst panel members. A public voting process was initiated, which successfully validated and provided qualitative nuance to our recommendations. Highlights include: 1) the critical importance of a multidisciplinary approach to the evaluation of patients with rNSCLC driven by shared clinical decision making of a multispecialty team of expert providers; 2) biomarker testing for rNSCLC; 3) a preference for neoadjuvant chemoimmunotherapy for stage III rNSCLC; 4) equipoise regarding the optimal management of patients with stage II between up-front surgery followed by adjuvant therapy and neoadjuvant/perioperative strategies; and 5) the robust preference for adjuvant targeted therapy for patients with rNSCLC and sensitizing EGFR and ALK tumor alterations. Our primary goals were to provide practical recommendations sensitive to the global differences in biology and resources for patients with rNSCLC, and to provide expert consensus guidance tailored to the individualized patient needs, goals, and preferences in their cancer care journey as these are areas where physicians must make daily clinical decisions in the absence of definitive data. These recommendations will continue to evolve as the treatment landscape for rNSCLC expands and more knowledge is acquired on the best therapeutic approach in specific patient and disease subgroups.

    皮肤黑色素瘤的发病率正在上升。早期诊断和治疗管理是增加生存机会的关键。对于可以完全切除治疗的局部晚期黑色素瘤患者,辅助-以及最近的新辅助-靶向治疗-BRAF和MEK抑制剂-以及免疫疗法-基于抗PD-1的治疗-提供了降低复发和远处转移风险的机会。对于不适合根治性治疗的晚期疾病患者,这些治疗提供了前所未有的总生存率的增加。来自西班牙医学肿瘤学会(SEOM)和西班牙多学科黑色素瘤小组(GEM)的一组医学肿瘤学家设计了这些指南,基于对现有最佳证据的全面审查。以下指南试图涵盖从诊断-临床的所有方面,病态,和分子分期,风险分层,辅助治疗,晚期疾病治疗,和幸存者的后续行动,包括特殊情况,如脑转移,难治性疾病,和治疗测序。我们的目标是在决策过程中帮助临床医生。
    Cutaneous melanoma incidence is rising. Early diagnosis and treatment administration are key for increasing the chances of survival. For patients with locoregional advanced melanoma that can be treated with complete resection, adjuvant-and more recently neoadjuvant-with targeted therapy-BRAF and MEK inhibitors-and immunotherapy-anti-PD-1-based therapies-offer opportunities to reduce the risk of relapse and distant metastases. For patients with advanced disease not amenable to radical treatment, these treatments offer an unprecedented increase in overall survival. A group of medical oncologists from the Spanish Society of Medical Oncology (SEOM) and Spanish Multidisciplinary Melanoma Group (GEM) has designed these guidelines, based on a thorough review of the best evidence available. The following guidelines try to cover all the aspects from the diagnosis-clinical, pathological, and molecular-staging, risk stratification, adjuvant therapy, advanced disease therapy, and survivor follow-up, including special situations, such as brain metastases, refractory disease, and treatment sequencing. We aim help clinicians in the decision-making process.

    自噬过程是指细胞内吸收细胞质(如蛋白质、核酸,微小的分子,完整的细胞器,等等)进入溶酶体,然后是细胞质的分解。大多数细胞蛋白被称为自噬的过程降解,这既是自然发生的活动,也是可能由细胞应激诱导的活动。自噬是一种系统,可以在紧张的情况下通过恢复代谢基础和摆脱亚细胞垃圾来保存细胞的完整性。这作为耐力反应的组成部分而发生。这种机制可能对疾病有影响,除了对单个细胞和组织的稳态以及对高等物种发育的控制之外。本研究的主要目的是讨论自噬在药物递送载体摄取途径中的作用指南。在本文中,我们讨论了自噬的含义和概念,自噬的机制,自噬在药物递送载体中的作用,自噬调节药物,用于自噬调节剂递送系统的纳米结构,等。在本文的后面,我们谈论如何提供化疗药物,siRNA以及自噬诱导剂和抑制剂。我们还谈到了要制造一种将纳米载体作为自噬调节剂的药物递送系统有多难。
    The process of autophagy refers to the intracellular absorption of cytoplasm (such as proteins, nucleic acids, tiny molecules, complete organelles, and so on) into the lysosome, followed by the breakdown of that cytoplasm. The majority of cellular proteins are degraded by a process called autophagy, which is both a naturally occurring activity and one that may be induced by cellular stress. Autophagy is a system that can save cells\' integrity in stressful situations by restoring metabolic basics and getting rid of subcellular junk. This happens as a component of an endurance response. This mechanism may have an effect on disease, in addition to its contribution to the homeostasis of individual cells and tissues as well as the control of development in higher species. The main aim of this study is to discuss the guidelines for the role of autophagy in drug delivery vector uptake pathways. In this paper, we discuss the meaning and concept of autophagy, the mechanism of autophagy, the role of autophagy in drug delivery vectors, autophagy-modulating drugs, nanostructures for delivery systems of autophagy modulators, etc. Later in this paper, we talk about how to deliver chemotherapeutics, siRNA, and autophagy inducers and inhibitors. We also talk about how hard it is to make a drug delivery system that takes nanocarriers\' roles as autophagy modulators into account.

    背景:本文件是法国胆道癌(BTC)治疗组间指南的摘要(肝内,肺门周围和远端胆管癌,和胆囊癌)于2023年9月出版,可在法国胃肠病学会(SNFGE)的网站上获得(www.tncd.org)。
    方法:这项合作工作是在参与BTC管理的法国医学和外科学会的主持下进行的。建议分为三类(A,B和C)根据直到2023年8月的科学证据水平。
    结果:BTC的诊断和分期主要基于增强计算机断层扫描,磁共振成像和(内窥镜)超声引导活检。治疗策略取决于BTC亚型和疾病阶段。对于局部疾病,建议手术后辅以卡培他滨。迄今为止,没有新辅助治疗得到验证。顺铂-吉西他滨化疗联合抗PD-L1抑制剂Durvalumab是晚期疾病的一线治疗标准。建议早期系统肿瘤分子谱分析来筛选可行的改变(IDH1突变,FGFR2重排,HER2扩增,BRAFV600E突变,MSI/dMMR状态,等。)并指导后续的治疗路线。在没有可操作的改变的情况下,FOLFOX化疗是唯一的二线标准治疗。迄今为止,尚无三线化疗标准。
    结论:这些指南旨在为日常临床实践提供个性化的治疗策略。每个BTC案例都应由多学科团队讨论。
    BACKGROUND: This document is a summary of the French intergroup guidelines of the management of biliary tract cancers (BTC) (intrahepatic, perihilar and distal cholangiocarcinomas, and gallbladder carcinomas) published in September 2023, available on the website of the French Society of Gastroenterology (SNFGE) (www.tncd.org).
    METHODS: This collaborative work was conducted under the auspices of French medical and surgical societies involved in the management of BTC. Recommendations were graded in three categories (A, B and C) according to the level of scientific evidence until August 2023.
    RESULTS: BTC diagnosis and staging is mainly based on enhanced computed tomography, magnetic resonance imaging and (endoscopic) ultrasound-guided biopsy. Treatment strategy depends on BTC subtype and disease stage. Surgery followed by adjuvant capecitabine is recommended for localised disease. No neoadjuvant treatment is validated to date. Cisplatin-gemcitabine chemotherapy combined to the anti-PD-L1 inhibitor durvalumab is the first-line standard of care for advanced disease. Early systematic tumour molecular profiling is recommended to screen for actionable alterations (IDH1 mutations, FGFR2 rearrangements, HER2 amplification, BRAFV600E mutation, MSI/dMMR status, etc.) and guide subsequent lines of treatment. In the absence of actionable alterations, FOLFOX chemotherapy is the only second-line standard-of-care. No third-line chemotherapy standard is validated to date.
    CONCLUSIONS: These guidelines are intended to provide a personalised therapeutic strategy for daily clinical practice. Each individual BTC case should be discussed by a multidisciplinary team.

    融合基因NRG1和NRG2,表皮生长因子(EGF)受体家族的成员,已经成为癌症的关键驱动因素。融合后,NRG1保留其EGF样活性结构域,结合到ERBB配体家族,并触发细胞内信号级联,促进不受控制的细胞增殖。NRG1基因融合的发生率因癌症类型而异,肺癌最普遍,为0.19至0.27%。CD74和SLC3A2是最常见的融合伴侣。基于RNA的下一代测序是检测NRG1和NRG2基因融合的主要方法,而pERBB3免疫组织化学可以作为鉴定NRG1阳性患者的快速预筛查工具。目前,没有批准的NRG1和NRG2靶向药物。常见的治疗方法包括pan-ERBB抑制剂,靶向ERBB2或ERBB3的小分子抑制剂和单克隆抗体。鉴于NRG1和NRG2在实体瘤中的现状,提出了诊断和治疗专家之间的共识,临床试验有望使更多NRG1和NRG2基因融合实体瘤患者受益。
    The fusion genes NRG1 and NRG2 , members of the epidermal growth factor (EGF) receptor family, have emerged as key drivers in cancer. Upon fusion, NRG1 retains its EGF-like active domain, binds to the ERBB ligand family, and triggers intracellular signaling cascades, promoting uncontrolled cell proliferation. The incidence of NRG1 gene fusion varies across cancer types, with lung cancer being the most prevalent at 0.19 to 0.27%. CD74 and SLC3A2 are the most frequently observed fusion partners. RNA-based next-generation sequencing is the primary method for detecting NRG1 and NRG2 gene fusions, whereas pERBB3 immunohistochemistry can serve as a rapid prescreening tool for identifying NRG1 -positive patients. Currently, there are no approved targeted drugs for NRG1 and NRG2 . Common treatment approaches involve pan-ERBB inhibitors, small molecule inhibitors targeting ERBB2 or ERBB3, and monoclonal antibodies. Given the current landscape of NRG1 and NRG2 in solid tumors, a consensus among diagnostic and treatment experts is proposed, and clinical trials hold promise for benefiting more patients with NRG1 and NRG2 gene fusion solid tumors.

    胆管癌(CCA)是肝内和肝外胆管的罕见恶性肿瘤。CCA主要由其解剖位置定义:肝内胆管癌与肝外胆管癌。肝门部胆管癌(HC)是肝外胆管癌的一种亚型,起源于肝总胆管,可以扩展到右和/或左肝胆管。辅助卡培他滨的前期手术是对早期疾病患者的护理标准,也是唯一的治愈性疗法。不幸的是,大多数患者存在局部晚期或转移性疾病,必须依靠全身治疗作为主要治疗手段.然而,即使是目前的全身治疗,生存仍然很贫穷。因此,研究的重点是开发靶向治疗和多模式策略,以改善整体预后.这篇综述讨论了HC的工作和管理,重点是最新的文献和正在进行的临床试验。
    Cholangiocarcinoma (CCA) is a rare malignancy of the intrahepatic and extrahepatic biliary ducts. CCA is primarily defined by its anatomic location: intrahepatic cholangiocarcinoma versus extrahepatic cholangiocarcinoma. Hilar cholangiocarcinoma (HC) is a subtype of extrahepatic cholangiocarcinoma that arises from the common hepatic bile duct and can extend to the right and/or left hepatic bile ducts. Upfront surgery with adjuvant capecitabine is the standard of care for patients who present with early disease and the only curative therapy. Unfortunately, most patients present with locally advanced or metastatic disease and must rely on systemic therapy as their primary treatment. However, even with current systemic therapy, survival is still poor. As such, research is focused on developing targeted therapies and multimodal strategies to improve overall prognosis. This review discusses the work-up and management of HC focused on the most up-to-date literature and ongoing clinical trials.

  • 文章类型: English Abstract
    RNA-based next-generation sequencing (NGS) has been recommended as a method for detecting fusion genes in non-small cell lung cancer (NSCLC) according to clinical practice guidelines and expert consensus. The primary targetable alterations in NSCLC consist of gene mutations and fusions, making the detection of gene mutations and fusions indispensable for assessing the feasibility of targeted therapies. Currently, the integration of DNA-based NGS and RNA-based NGS allows for simultaneous detection of gene mutations and fusions and has been partially implemented in clinical practice. However, standardized guidelines and criteria for the significance, application scenarios, and quality control of RNA-based NGS in fusion gene detection are still lacking in China. This consensus aims to provide further clarity on the practical significance, application scenarios, and quality control measures of RNA-based NGS in fusion gene detection. Additionally, it offers guiding recommendations to facilitate the clinical implementation of RNA-based NGS in the diagnosis and treatment of NSCLC, ultimately maximizing the benefits for patients from fusion gene detection.

    背景:结直肠癌是一种复杂的疾病,死亡率很高。随着时间的推移,随着现代化疗和靶向治疗方案的发展,转移性结直肠癌(mCRC)的治疗方法逐渐得到改善.然而,由于这种情况固有的异质性,为靶向治疗确定可靠的预测性生物标志物仍然具有挑战性.最近有希望的分类系统-共有分子亚型(CMS)系统-提供了根据mCRC患者独特的生物学和分子特征对其进行分类的潜力。已经定义了四个不同的CMS类别:免疫(CMS1),规范(CMS2),代谢(CMS3),和间充质(CMS4)。然而,目前尚无将患者准确分类为CMS类别的标准化方案.为了应对这一挑战,逆转录聚合酶链反应(RT-qPCR)和下一代基因组测序(NGS)技术有望将mCRC患者精确分类为CMS.
    目的:研究mCRC患者是否可以使用标准化的分子生物学工作流程分为CMS类别。
    方法:这项观察性研究在智利大学临床医院进行,纳入了接受化疗和/或靶向治疗的不可切除的mCRC患者。采用分子生物学技术来分析来自这些患者的原发性肿瘤样品。RT-qPCR用于评估与纤维化(TGF-β和β-catenin)和细胞生长途径(c-MYC)相关的基因的表达。使用25个基因组(TumorSec)进行NGS以鉴定特定的基因组突变。然后根据肿瘤委员会的临床共识将患者分为四个CMS类别之一。在参与本研究之前,所有患者均已获得知情同意。所有技术均在智利大学进行。
    结果:对26名患者进行了研究,然后由肿瘤委员会进行评估以确定特定的CMS。其中,23%(n=6),19%(n=5),31%(n=8),19%(n=5)分别被分类为CMS1,CMS2,CMS3和CMS4。此外,8%的患者(n=2)不能被分为四个CMS类别中的任何一个。总样本的中位总生存期为28个月,CMS1、CMS2、CMS3和CMS4分别为11、20、30和45个月,组间差异无统计学意义。
    结论:分子生物学工作流程和临床共识分析可用于对mCRC患者进行准确分类。这个分类过程,将患者分为四个CMS类别,在改进针对mCRC特定特征的研究策略和靶向治疗方面具有重要潜力。
    BACKGROUND: Colorectal cancer is a complex disease with high mortality rates. Over time, the treatment of metastatic colorectal cancer (mCRC) has gradually improved due to the development of modern chemotherapy and targeted therapy regimens. However, due to the inherent heterogeneity of this condition, identifying reliable predictive biomarkers for targeted therapies remains challenging. A recent promising classification system-the consensus molecular subtype (CMS) system-offers the potential to categorize mCRC patients based on their unique biological and molecular characteristics. Four distinct CMS categories have been defined: immune (CMS1), canonical (CMS2), metabolic (CMS3), and mesenchymal (CMS4). Nevertheless, there is currently no standardized protocol for accurately classifying patients into CMS categories. To address this challenge, reverse transcription polymerase chain reaction (RT-qPCR) and next-generation genomic sequencing (NGS) techniques may hold promise for precisely classifying mCRC patients into their CMSs.
    OBJECTIVE: To investigate if mCRC patients can be classified into CMS categories using a standardized molecular biology workflow.
    METHODS: This observational study was conducted at the University of Chile Clinical Hospital and included patients with unresectable mCRC who were undergoing systemic treatment with chemotherapy and/or targeted therapy. Molecular biology techniques were employed to analyse primary tumour samples from these patients. RT-qPCR was utilized to assess the expression of genes associated with fibrosis (TGF-β and β-catenin) and cell growth pathways (c-MYC). NGS using a 25-gene panel (TumorSec) was performed to identify specific genomic mutations. The patients were then classified into one of the four CMS categories according to the clinical consensus of a Tumour Board. Informed consent was obtained from all the patients prior to their participation in this study. All techniques were conducted at University of Chile.
    RESULTS: Twenty-six patients were studied with the techniques and then evaluated by the Tumour Board to determine the specific CMS. Among them, 23% (n = 6), 19% (n = 5), 31% (n = 8), and 19% (n = 5) were classified as CMS1, CMS2, CMS3, and CMS4, respectively. Additionally, 8% of patients (n = 2) could not be classified into any of the four CMS categories. The median overall survival of the total sample was 28 mo, and for CMS1, CMS2, CMS3 and CMS4 it was 11, 20, 30 and 45 mo respectively, with no statistically significant differences between groups.
    CONCLUSIONS: A molecular biology workflow and clinical consensus analysis can be used to accurately classify mCRC patients. This classification process, which divides patients into the four CMS categories, holds significant potential for improving research strategies and targeted therapies tailored to the specific characteristics of mCRC.
