    这篇综述讨论了预防最常见的实体瘤类型的脑转移的主题,即,肺癌,乳腺癌和黑色素瘤.在每种肿瘤类型中,脑转移的风险与疾病状态和分子亚型有关(即,EGFR突变型非小细胞肺癌,HER2阳性和三阴性乳腺癌,BRAF和NRAF突变黑色素瘤)。预防性颅骨照射是对化疗有反应的小细胞肺癌患者的标准护理,但代价是晚期神经认知能力下降。最近,在临床试验中,一些能够靶向分子改变驱动肿瘤生长的分子药物已被证明在预防继发性脑复发方面是有效的.EGFR突变或ALK重排的非小细胞肺癌抑制剂就是这种情况。图卡替尼和曲妥珠单抗-deruxtecan治疗HER2阳性乳腺癌,BRAF抑制剂治疗黑色素瘤。强调对脑转移风险的无症状患者进行MRI筛查的必要性。
    This review discusses the topic of prevention of brain metastases from the most frequent solid tumor types, i.e., lung cancer, breast cancer and melanoma. Within each tumor type, the risk of brain metastasis is related to disease status and molecular subtype (i.e., EGFR-mutant non-small cell lung cancer, HER2-positive and triple-negative breast cancer, BRAF and NRAF-mutant melanoma). Prophylactic cranial irradiation is the standard of care in patients in small cell lung cancer responsive to chemotherapy but at the price of late neurocognitive decline. More recently, several molecular agents with the capability to target molecular alterations driving tumor growth have proven as effective in the prevention of secondary relapse into the brain in clinical trials. This is the case for EGFR-mutant or ALK-rearranged non-small cell lung cancer inhibitors, tucatinib and trastuzumab-deruxtecan for HER2-positive breast cancer and BRAF inhibitors for melanoma. The need for screening with an MRI in asymptomatic patients at risk of brain metastases is emphasized.

    原发性肿瘤切除术和转移瘤切除术可能对许多转移性结直肠癌(mCRC)患者有益。
    评估单纯化疗辅助治疗与化疗加靶向药物(TA)术后生存结果的差异。
    回顾性队列研究。
    2010年1月1日至2017年12月31日接受原发性结直肠肿瘤和远处转移手术切除并接受辅助治疗的mCRC患者纳入台湾癌症注册中心。我们分析了接受单独辅助化疗和化疗加TAs的可切除或最初不可切除的mCRC患者的总生存期。
    我们招募了1124和542名可切除和最初不可切除的mCRC患者,分别。辅助化疗加TA和单独化疗导致可切除mCRC患者的死亡率相似[调整风险比(aHR)=1.13;95%置信区间(CI),0.93-1.36];然而,在新辅助治疗后接受了转阴手术的最初不可切除的mCRC患者中,其死亡率略有降低(aHR=0.81;95%CI,0.62-1.06).术前接受超过9个周期的TAs和抗表皮生长因子受体药物的患者的亚组分析显示aHRs为0.48(95%CI,0.27-0.87)和0.33(95%CI,0.18-0.60),分别。
    辅助化疗加TAs可以改善最初不可切除的肿瘤患者的生存率,这些患者在新辅助治疗后接受了转阴手术,尤其是那些对靶向治疗反应良好的人。我们的研究强调了在选择辅助治疗方案时,根据肿瘤可切除性对mCRC患者进行分层的重要性。
    UNASSIGNED: Primary tumor resection and metastasectomy may be beneficial for many patients with metastatic colorectal cancer (mCRC).
    UNASSIGNED: To assess the differences in postoperative survival outcomes between adjuvant therapy with chemotherapy alone and chemotherapy plus targeted agents (TAs).
    UNASSIGNED: Retrospective cohort study.
    UNASSIGNED: Patients with mCRC who underwent surgical resection for primary colorectal tumor and distant metastases and received adjuvant therapy from 1 January 2010 to 31 December 2017 were enrolled in the Taiwan Cancer Registry. We analyzed the overall survival of patients with resectable or initially unresectable mCRC who received adjuvant chemotherapy alone and chemotherapy plus TAs.
    UNASSIGNED: We enrolled 1124 and 542 patients with resectable and initially unresectable mCRC, respectively. Adjuvant chemotherapy plus TAs and chemotherapy alone resulted in similar mortality rates among patients with resectable mCRC [adjusted hazard ratio (aHR) = 1.13; 95% confidence interval (CI), 0.93-1.36]; however, it marginally reduced the mortality rate among patients with initially unresectable mCRC who underwent conversion surgery after neoadjuvant therapy (aHR = 0.81; 95% CI, 0.62-1.06). The subgroup analysis of patients who received more than nine cycles of TAs preoperatively and anti-epidermal growth factor receptor agents revealed aHRs of 0.48 (95% CI, 0.27-0.87) and 0.33 (95% CI, 0.18-0.60), respectively.
    UNASSIGNED: Adjuvant chemotherapy plus TAs may improve survival in patients with initially unresectable tumors who underwent conversion surgery following neoadjuvant therapy with TAs, especially in those who respond well to the targeted therapy. Our study underscores the importance of stratifying patients with mCRC based on tumor resectability when selecting the adjuvant therapy regimen.

    为了评估一线靶向药物(TA)或氟达拉滨治疗的影响,环磷酰胺,和基于利妥昔单抗(FCR)的化学免疫疗法(CIT)与普通人群中年龄和性别匹配的个体相比,我们对3期临床试验进行了综合分析,包括两个FLAIR子研究,ECOG1912和CLL13试验。受限平均生存时间(RMST),结果分析中的另一种测量方法是捕获整个疾病史的OS变化,用于最大限度地减少与短随访时间的试验相关的偏见。与接受CIT(5年RMST,56.9个月;95%CI:56.7-58.2)。此外,治疗组与AGMGP的OS比较表明,在治疗开始后的前5年内,TA可能减轻CLL对OS的影响.总之,将接受TAs治疗的CLL患者与意大利年龄和性别匹配的一般人群(AGMGP)进行比较,5年RMST差异为-0.4个月(95%CI:-0.8~0.2;p=0.10).当将接受TA治疗的CLL患者与美国AGMGP进行比较时,观察到类似的趋势(5年RMST差异,0.3个月;95%CI:-0.1至0.9;p=0.12)。相比之下,与意大利队列(5年RMST差异:-1.6个月;95%CI:-2.4至-0.9;p<0.0001)和美国AGMGP队列(5年RMST差异:-0.9个月;95%CI:-1.7至-0.2;p=0.015)相比,接受FCR治疗的CLL患者表现出持续的OS差异。尽管这些结果支持TA作为年轻CLL患者的首选一线治疗,我们必须承认,临床试验中患者选择标准和临床概况的差异,需要对这些发现进行谨慎的解释,这些结果应被视为具有方向性和假设生成性.需要更长的随访时间来评估接受TA治疗的年轻CLL患者相对于AGMGP的生存改善。
    To assess the impact of first-line treatment with targeted agents (TAs) or fludarabine, cyclophosphamide, and rituximab (FCR)-based chemo-immunotherapy (CIT) on overall survival (OS) compared to age- and sex-matched individuals in the general population, we conducted an aggregated analysis of phase 3 clinical trials, including the two FLAIR sub-studies, ECOG1912, and CLL13 trials. The restricted mean survival time (RMST), an alternative measure in outcome analyses capturing OS changes over the entire history of the disease, was used to minimize biases associated with the short follow-up time of trials. Patients treated with TAs demonstrated a higher 5-year RMST (58.1 months; 95% CI: 57.4 to 58.8) compared to those treated with CIT (5-year RMST, 56.9 months; 95% CI: 56.7-58.2). Furthermore, the OS comparison of treatment groups with the AGMGP suggests that TAs may mitigate the impact of CLL on OS during the first five years post-treatment initiation. In summary, the 5-year RMST difference was -0.4 months (95% CI: -0.8 to 0.2; p = 0.10) when comparing CLL patients treated with TAs to the Italian age- and gender-matched general population (AGMGP). A similar trend was observed when CLL patients treated with TAs were compared to the US AGMGP (5-year RMST difference, 0.3 months; 95% CI: -0.1 to 0.9; p = 0.12). In contrast, CLL patients treated with FCR exhibited sustained OS differences when compared to both the Italian cohort (5-year RMST difference: -1.6 months; 95% CI: -2.4 to -0.9; p < 0.0001) and the US AGMGP cohort (5-year RMST difference: -0.9 months; 95% CI: -1.7 to -0.2; p = 0.015). Although these results support TAs as the preferred first-line treatment for younger CLL patients, it is crucial to acknowledge that variations in patient selection criteria and clinical profiles across clinical trials necessitate a cautious interpretation of these findings that should be viewed as directional and hypothesis-generating. A longer follow-up is needed to assess the survival improvement of younger CLL patients treated with TAs relative to the AGMGP.

    在过去的20年中,转移性结直肠癌(mCRC)的系统治疗有了很大改善。5FU的一线和二线组合,奥沙利铂,还有伊立替康,有或没有抗血管生成和/或抗EGFR抗体,在世纪之交后不久获得批准。近10年来没有看到进一步的胜利,直到最初获得雷戈非尼的批准,并在三氟尿苷/替匹拉嘧啶之后不久。通过分子谱分析对肿瘤生物学的日益了解导致了进一步的治疗选择。这里,我们回顾了mCRC晚期治疗方案的最新临床数据,如果有的话,重点是随机试验。我们包括针对未选择的患者的选择建议和仅应在具有不同肿瘤特征的患者中提供的治疗方法(例如,BRAF突变,KRASG12C突变,HER2扩增,缺乏MMR,或NTRK基因融合)。
    Systemic treatment of metastatic colorectal cancer (mCRC) has improved considerably over the past 20 years. First- and second-line combinations of 5FU, oxaliplatin, and irinotecan, with or without anti-angiogenic and/or anti-EGFR antibodies, were approved shortly after the turn of the millennium. Further triumphs were not seen for almost 10 years, until the approval of initially regorafenib and shortly after trifluridine/tipiracil. A growing understanding of tumor biology through molecular profiling has led to further treatment options. Here, we review the most recent clinical data for late-line treatment options in mCRC, focusing on randomized trials if available. We include recommendations for options in unselected patients and therapies that should only be offered in patients with distinct tumor profiles (e.g., BRAF mutations, KRAS G12C mutations, HER2 amplification, deficient MMR, or NTRK gene fusions).

    恶性胸膜间皮瘤的发病率有望在全球范围内增加。人们热切期待这种恶性肿瘤的新治疗方案,以提高患者的生存率和生活质量。本文重点介绍了该领域最新进展的结果,分析几个相关试验的数据。异质性肿瘤微环境与生物学,加上低突变负担,对治疗此类肿瘤构成挑战。到目前为止,没有单一的生物标志物与靶向治疗的发展密切相关;因此,通常需要组合策略来改善结果。本地应用的疫苗,基因工程免疫细胞群体如T细胞的扩增,阻断抑制抗肿瘤反应的免疫检查点和化学免疫疗法是有望改变间皮瘤治疗格局的最有希望的选择之一.
    The incidence of malignant pleural mesothelioma is expected to increase globally. New treatment options for this malignancy are eagerly awaited to improve the survival and quality of life of patients. The present article highlights the results of recent advances in this field, analyzing data from several relevant trials. The heterogeneous tumor microenvironment and biology, together with the low mutational burden, pose a challenge for treating such tumors. So far, no single biomarker has been soundly correlated with targeted therapy development; thus, combination strategies are often required to improve outcomes. Locally applied vaccines, the expansion of genetically engineered immune cell populations such as T cells, the blockage of immune checkpoints that inhibit anti-tumorigenic responses and chemoimmunotherapy are among the most promising options expected to change the mesothelioma treatment landscape.

    基于其在正常组织中的缺失及其在肿瘤发生和肿瘤进展中的作用,胰岛素样生长因子2mRNA结合蛋白3(IGF2BP3),RNA上的N6-甲基腺苷(M6A)的读者,代表了一些癌症治疗的推定有价值和特异性的靶标。在这项研究中,我们进行了生物信息学分析和免疫组织化学(IHC),发现IGF2BP3在卵巢癌(OC)的肿瘤上皮细胞和成纤维细胞中高表达,并与不良预后有关,转移,OC患者的化疗敏感性。特别是,我们发现敲低IGF2BP3表达通过降低c-MYC蛋白水平抑制OC细胞系的恶性表型,VEGF,CDK2、CDK6和STAT1。探讨IGF2BP3作为OC治疗靶点的可行性,设计了一种小分子AE-848,并通过分子操作环境(MOE)进行了筛选,不仅可以重复上述敲低实验的结果,而且可以降低M2巨噬细胞和肿瘤相关巨噬细胞中c-MYC的表达,并促进细胞因子IFN-γ和TNF-α的分泌。两种携带OC的动物的药效学模型表明,AE-848的全身治疗通过降低肿瘤相关抗原(c-MYC/VEGF/Ki67/CDK2)的表达和改善抗肿瘤作用显着抑制肿瘤生长。巨噬细胞的作用。这些结果表明,AE-848可以通过破坏IGF2BP3的靶向mRNA的稳定性来抑制OC细胞的生长和进展,并且可能是用于OC治疗的靶向药物。
    Based on its absence in normal tissues and its role in tumorigenesis and tumor progression, insulin-like growth factor 2 mRNA-binding protein 3 (IGF2BP3), a reader of N6-methyladenosine (M6A) on RNA, represents a putative valuable and specific target for some cancer therapy. In this study, we performed bioinformatic analysis and immunohistochemistry (IHC) to find that IGF2BP3 was highly expressed in tumor epithelial cells and fibroblasts of ovarian cancer (OC), and was associated with poor prognosis, metastasis, and chemosensitivity in OC patients. In particular, we discovered that knockdown IGF2BP3 expression inhibited the malignant phenotype of OC cell lines by decreasing the protein levels of c-MYC, VEGF, CDK2, CDK6, and STAT1. To explore the feasibility of IGF2BP3 as a therapeutic target for OC, a small molecular AE-848 was designed and screened by molecular operating environment (MOE), which not only could duplicate the above results of knockdown assay but also reduced the expression of c-MYC in M2 macrophages and tumor-associated macrophages and promoted the cytokine IFN-γ and TNF-α secretion. The pharmacodynamic models of two kinds of OC bearing animals were suggested that systemic therapy with AE-848 significantly inhibited tumor growth by reducing the expression of tumor-associated antigen (c-MYC/VEGF/Ki67/CDK2) and improving the anti-tumor effect of macrophages. These results suggest that AE-848 can inhibit the growth and progression of OC cells by disrupting the stability of the targeted mRNAs of IGF2BP3 and may be a targeted drug for OC treatment.

    由于人口统计学变化,老年妇女的乳腺癌(BC)是一个日益严重的健康问题。BC往往出现较晚,可能接受少于标准治疗方案。更多的时候,老年患者的BC为内分泌阳性(HR+)。患有转移性BC(mBC)的老年患者的治疗代表了治疗挑战。近年来,由于在临床实践中引入了新的靶向药物,因此HR+/Her2阴性患者的治疗环境发生了变化,改善了患者的预后。老年患者只占所有参加临床试验的患者的一小部分,到目前为止,目前尚无标准化指南为该患者人群确定最佳治疗方案.这可能导致治疗不足或过度治疗,影响患者发病率和死亡率。用于定制老年患者治疗的老年评估工具未得到充分利用,因为它们很长且难以在繁忙的常规临床实践中应用。由于所有这些原因,迫切需要提供有关HR+mBC老年患者最佳治疗的数据.在这里,我们报告了有关HR+Her2阴性mBC老年患者治疗方案的随机临床试验数据和真实世界证据,并探讨了未来的治疗方向.
    Breast cancer (BC) in elderly women is an increasing health issue due to demographic changes. BC tends to present later and may receive less than standard treatment options. More often, BC in elderly patients is endocrine-positive (HR+). The treatment of elderly patients with metastatic BC (mBC) represents a therapeutic challenge. In recent years, the treatment landscape of patients that are HR+/Her2-negative has changed due to the introduction in clinical practice of new targeted drugs, which have improved patient outcomes. Elderly patients are a small percentage of all patients enrolled in clinical trials and, to date, there are no standardized guidelines that define the best treatment option for this patient population. This can lead to undertreatment or overtreatment, impacting patient morbidity and mortality. Geriatric Assessment tools to tailor the treatment in elderly patients are underused because they are long and difficult to apply in a busy routine clinical practice. For all these reasons, there is an urgent need to produce data about the best treatment for elderly patients with HR+ mBC. Herein, we report data from randomized clinical trials and real-world evidence on the therapeutic options for HR+ Her2-negative mBC elderly patients and explore future treatment directions.

    乳腺癌是全球最常见的癌症,放射治疗在局部辅助治疗中起着重要作用。近年来,我们已经看到辅助靶向系统治疗的出现改善了复发高危患者的预后.非转移性乳腺癌的靶向治疗和局部放射疗法的组合的实践通常由于证据水平低和缺乏经过验证的建议而仍然是异质的。这篇文献综述涵盖了免疫治疗,CDK4/6抑制剂,PARP抑制剂和抗Her2疗法。将这些靶向全身疗法与放射疗法相结合可以增强局部治疗。最佳治疗顺序和最大协同作用的分级仍有待定义。然而,虽然功效可能会增强,健康组织的放射致敏也可能导致毒性增加。似乎有可能继续免疫疗法,曲妥珠单抗,帕妥珠单抗,局部乳腺和淋巴结照射期间的TDM-1或拉帕替尼。PARP抑制剂和CDK4/6抑制剂仍有待暂停,由于缺乏佐剂设置的数据及其半衰期短,这不需要长时间停药。与新的抗体-药物偶联物一样,辅助放射治疗需要前瞻性数据.
    Breast cancer is the first most common cancer worldwide, and radiation therapy has a major role to play in locoregional adjuvant treatment. In recent years, we have seen the emergence of adjuvant targeted systemic therapies improving the prognosis of patients at high risk of recurrence. Practices concerning combinations of targeted therapies and locoregional radiation therapy for non-metastatic breast cancers often remain heterogeneous due to the low level of evidence and lack of validated recommendations. This literature review covers immunotherapy, CDK 4/6 inhibitors, PARP inhibitors and anti-Her2 therapies. Combining these targeted systemic therapies with radiation therapy could potentiate local treatment. The optimal therapeutic sequence and fractionation for maximum synergistic effect remain to be defined. However, while efficacy may be enhanced, radiosensitization of healthy tissue may also lead to increased toxicity. It appears possible to continue immunotherapy, trastuzumab, pertuzumab, TDM-1 or lapatinib during locoregional breast and lymph node irradiation. PARP inhibitors and CDK4/6 inhibitors are still to be suspended, due to the lack of data in the adjuvant setting and their short half-life, which does not necessitate prolonged discontinuation. As with the new antibody-drug conjugates, prospective data are needed in conjunction with adjuvant radiation therapy.

    肺动脉高压(PAH)是一种恶性肺血管综合征,其特征是肺血管阻力和肺动脉压进行性增加,最终导致右心衰竭甚至死亡.尽管PAH的确切机制尚未完全了解,肺血管收缩,血管重塑,免疫和炎症反应,和血栓形成被认为与PAH的发生和发展有关。在非目标特工时代,PAH的预后非常差,中位生存时间仅为2.8年。随着对PAH病理生理机制的深入了解以及药物研究的进展,在过去的30年中,PAH特异性治疗药物发展迅速,但他们主要关注三种经典的信号通路,即内皮素途径,一氧化氮途径,和前列环素途径。这些药物显著改善了肺血流动力学,心功能,运动耐受力,生活质量,和PAH患者的预后,但只能在有限的程度上降低肺动脉压和右心室后负荷。目前的靶向药物可延缓PAH的进展,但不能从根本上逆转肺血管重塑。通过不懈的努力,新的治疗药物如索特西普已经出现,为这一领域注入新的活力。这篇综述全面总结了PAH的一般治疗方法,包括肌力强化剂和血管加压药,利尿剂,抗凝剂,一般血管扩张剂,和贫血管理。此外,本文综述了针对3条经典信号通路的12种特异性药物的药理特性和最新研究进展,以及双重-,序贯三重-,以及基于上述靶向药物的初始三联疗法策略。更关键的是,寻找新的PAH治疗靶点从未停止,随着近年来的巨大进步,本综述概述了目前处于探索阶段的潜在PAH治疗药物,为PAH的治疗提供新的方向,改善PAH患者的长期预后。
    Pulmonary arterial hypertension (PAH) is a malignant pulmonary vascular syndrome characterized by a progressive increase in pulmonary vascular resistance and pulmonary arterial pressure, which eventually leads to right heart failure and even death. Although the exact mechanism of PAH is not fully understood, pulmonary vasoconstriction, vascular remodeling, immune and inflammatory responses, and thrombosis are thought to be involved in the development and progression of PAH. In the era of non-targeted agents, PAH had a very dismal prognosis with a median survival time of only 2.8 years. With the deep understanding of the pathophysiological mechanism of PAH as well as advances in drug research, PAH-specific therapeutic drugs have developed rapidly in the past 30 years, but they primarily focus on the three classical signaling pathways, namely the endothelin pathway, nitric oxide pathway, and prostacyclin pathway. These drugs dramatically improved pulmonary hemodynamics, cardiac function, exercise tolerance, quality of life, and prognosis in PAH patients, but could only reduce pulmonary arterial pressure and right ventricular afterload to a limited extent. Current targeted agents delay the progression of PAH but cannot fundamentally reverse pulmonary vascular remodeling. Through unremitting efforts, new therapeutic drugs such as sotatercept have emerged, injecting new vitality into this field. This review comprehensively summarizes the general treatments for PAH, including inotropes and vasopressors, diuretics, anticoagulants, general vasodilators, and anemia management. Additionally, this review elaborates the pharmacological properties and recent research progress of twelve specific drugs targeting three classical signaling pathways, as well as dual-, sequential triple-, and initial triple-therapy strategies based on the aforementioned targeted agents. More crucially, the search for novel therapeutic targets for PAH has never stopped, with great progress in recent years, and this review outlines the potential PAH therapeutic agents currently in the exploratory stage to provide new directions for the treatment of PAH and improve the long-term prognosis of PAH patients.
