    蛋白酶体抑制剂(PIs)是多发性骨髓瘤和AL淀粉样变性患者联合治疗的骨干,同时也出现在Waldenström巨球蛋白血症和其他恶性肿瘤中。PIs作用于蛋白酶体肽酶,由于积累聚集而导致蛋白质组不稳定,展开,和/或受损的多肽;持续的蛋白质组不稳定性然后诱导细胞周期停滞和/或细胞凋亡。卡菲佐米,静脉内不可逆PI,与口服给药的Ixazomib或静脉内可逆性PI如硼替佐米相比,表现出更严重的心血管毒性特征。心血管毒性包括心力衰竭,高血压,心律失常,和急性冠脉综合征。因为PI是血液系统恶性肿瘤和淀粉样变性治疗的关键组成部分,管理他们的心血管毒性包括识别有风险的患者,在临床前水平早期诊断毒性,并在需要时提供心脏保护。未来的研究需要阐明潜在的机制,改善风险分层,定义最优管理策略,并开发具有安全心血管特征的新PI。
    Proteasome inhibitors (PIs) are the backbone of combination treatments for patients with multiple myeloma and AL amyloidosis, while also indicated in Waldenström\'s macroglobulinemia and other malignancies. PIs act on proteasome peptidases, causing proteome instability due to accumulating aggregated, unfolded, and/or damaged polypeptides; sustained proteome instability then induces cell cycle arrest and/or apoptosis. Carfilzomib, an intravenous irreversible PI, exhibits a more severe cardiovascular toxicity profile as compared with the orally administered ixazomib or intravenous reversible PI such as bortezomib. Cardiovascular toxicity includes heart failure, hypertension, arrhythmias, and acute coronary syndromes. Because PIs are critical components of the treatment of hematological malignancies and amyloidosis, managing their cardiovascular toxicity involves identifying patients at risk, diagnosing toxicity early at the preclinical level, and offering cardioprotection if needed. Future research is required to elucidate underlying mechanisms, improve risk stratification, define the optimal management strategy, and develop new PIs with safe cardiovascular profiles.

    临床医生在患者接触期间的时间有限,这可能导致患者的担忧得不到解决。这项研究的目的是测试电子患者报告的结果生活质量工具(PROQOL)是否可以改善癌症患者的生活质量(QOL)。
    这项单中心非盲前瞻性临床试验将患者(2:1)随机接受PROQOL与常规治疗(UC)。纳入了两个患者队列:血液系统恶性肿瘤(多发性骨髓瘤[MM]或轻链淀粉样变性[AL])和实体瘤(头颈部[H/N]或妇科[GYN]恶性肿瘤)。主要终点是通过单项目线性模拟自我评估测量的患者报告的12个月时的QOL。对患者的价值和对临床医生工作流程的影响是使用“值得吗”调查来衡量的。该研究有能力检测组间0.5个标准偏差差异。
    共纳入383例患者,171配MM,62AL,113GYN,2016年7月至2018年4月期间为37H/N,随访12个月。男性患者为171例(44.6%),中位年龄为62岁(范围31-87)。最常选择的关注是身体健康(30.9%),其次是癌症诊断和治疗(29.1%)。12个月时,PROQOL的平均QOL为7.12,UC(0-10量表)为6.98,总体上(p=0.56)或在血液学或实体瘤队列中没有组间差异,分别。在患者中,74%的人认为PROQOL工具是值得的,86%的人会再次选择PROQOL,81%的人会推荐给其他人。在临床医生中,95%的人回答说PROQOL是值得的,并且认为PROQOL不会对他们的工作流程产生负面影响。
    虽然我们没有证明PROQOL组和UC组之间的QOL差异,但PROQOL工具在确定患者的主要关注点方面具有相当大的价值,对患者和临床医生来说都是值得的。
    UNASSIGNED: Clinicians have limited time during patient encounters which can result in patients\' concerns not being addressed. This study\'s objective was to test whether an electronic patient-reported outcome quality of life tool (PROQOL) in which patients identify their primary concern during clinic visits improves cancer patient quality of life (QOL).
    UNASSIGNED: This single center non-blinded prospective clinical trial randomized patients (2:1) to PROQOL versus usual care (UC). Two patient cohorts were enrolled: those with hematologic malignancies (multiple myeloma [MM] or light chain amyloidosis [AL]) and solid tumors (head and neck [H/N] or gynecologic [GYN] malignancies). Primary endpoint was patient-reported QOL at 12 months measured by a single-item Linear Analog Self-Assessment. Value to patients and impact on clinician workflow was measured using a \"was it worth it\" survey. The study was powered to detect a 0.5 standard deviation difference between groups.
    UNASSIGNED: Overall 383 patients were enrolled, 171 with MM, 62 AL, 113 GYN, and 37 H/N between July 2016 and April 2018, with 12-month follow-up. There were 171 (44.6%) male patients and median age was 62 years (range 31-87). The most often selected concern was physical health (30.9%), and second was cancer diagnosis and treatment (29.1%). Mean QOL was 7.12 for PROQOL and 6.98 for UC (0-10 scale) at 12 months, with no between-group difference overall (p = 0.56) or within hematologic or solid tumor cohorts, respectively. Among patients, 74% thought the PROQOL tool was worthwhile, 86% would choose PROQOL again, and 81% would recommend it to others. Among clinicians, 95% responded that PROQOL was worthwhile and did not think that PROQOL negatively impacted their workflow.
    UNASSIGNED: Although we did not demonstrate a QOL difference between PROQOL and UC groups; the PROQOL tool held considerable value in identifying patients\' main concerns over time and was worthwhile for patients and clinicians.

    人类癌症产生于获得广泛遗传改变的细胞群,其中大部分是治疗性治疗的目标,或被用作患者危险分层的预后因素。其中,拷贝数改变(CNA)相当频繁。目前,几种分子生物学技术,如微阵列,NGS和单细胞方法用于定义肿瘤样品的基因组谱。需要使用生物信息学方法,特别是使用计算算法来分析输出数据。分子生物学工具通过比较任一平均探针信号来估计基线区域,或参考基因组的读数数量。然而,当肿瘤表现出复杂的核型时,这种类型的方法可能会使基线区域估计失败,从而导致CNA调用中的错误。为了克服这个问题,我们设计了一个R包,BoBafit,能够检查,最终,要调整基线区域,根据肿瘤特异性改变的背景和样本特异性聚集的基因组病变。选择了几个数据库来设置和验证设计的软件包,从而证明了BoBafit调整来自不同肿瘤和分析技术的拷贝数(CN)数据的潜力。相关性,分析强调,多达25%的样本需要基线区域调整和重新定义CNAs调用,从而导致患者预后风险分类的改变。我们支持在CN分析生物信息学管道中实施BoBafit,以确保患者在风险类别中的正确分层,无论肿瘤类型。
    Human cancer arises from a population of cells that have acquired a wide range of genetic alterations, most of which are targets of therapeutic treatments or are used as prognostic factors for patient\'s risk stratification. Among these, copy number alterations (CNAs) are quite frequent. Currently, several molecular biology technologies, such as microarrays, NGS and single-cell approaches are used to define the genomic profile of tumor samples. Output data need to be analyzed with bioinformatic approaches and particularly by employing computational algorithms. Molecular biology tools estimate the baseline region by comparing either the mean probe signals, or the number of reads to the reference genome. However, when tumors display complex karyotypes, this type of approach could fail the baseline region estimation and consequently cause errors in the CNAs call. To overcome this issue, we designed an R-package, BoBafit , able to check and, eventually, to adjust the baseline region, according to both the tumor-specific alterations\' context and the sample-specific clustered genomic lesions. Several databases have been chosen to set up and validate the designed package, thus demonstrating the potential of BoBafit to adjust copy number (CN) data from different tumors and analysis techniques. Relevantly, the analysis highlighted that up to 25% of samples need a baseline region adjustment and a redefinition of CNAs calls, thus causing a change in the prognostic risk classification of the patients. We support the implementation of BoBafit within CN analysis bioinformatics pipelines to ensure a correct patient\'s stratification in risk categories, regardless of the tumor type.

    骨骼相关事件(SRE)是骨转移的并发症,具有严重的患者和经济负担。Denosumab是核因子-κB配体(RANKL)抑制剂的受体激活剂,已被批准用于多发性骨髓瘤患者和实体瘤骨转移患者的SRE预防。在第三阶段试验中,denosumab在将首次研究SRE的风险降低17%(首次研究SRE的中位时间延迟8.2个月)和首次和随后的研究SRE的风险降低18%的优势多种实体瘤类型,包括一些多发性骨髓瘤患者。Denosumab还改善了疼痛结果,减少了对强效阿片类药物的需求。此外,一项3期试验显示,在新诊断的多发性骨髓瘤患者中,denosumab在延迟至首次SRE的时间方面不劣于唑来膦酸.Denosumab每4周有一个方便的120mg推荐的皮下给药方案。与denosumab相关的罕见但严重的毒性包括颌骨坏死,低钙血症,和非典型股骨骨折事件,治疗中断后报告多处椎骨骨折。在denosumab十年的真实世界临床经验之后,我们仍在学习denosumab的最佳使用和剂量。尽管出现了新颖有效的抗肿瘤疗法,抗吸收治疗预防SRE的临床应用仍有很强的理由.正在进行的研究旨在优化使用denosumab预防SRE的患者的临床管理,同时保持安全性和有效性。
    Skeletal-related events (SREs) are complications of bone metastases and carry a significant patient and economic burden. Denosumab is a receptor activator of nuclear factor-κB ligand (RANKL) inhibitor approved for SRE prevention in patients with multiple myeloma and patients with bone metastases from solid tumors. In phase 3 trials, denosumab showed superiority to the bisphosphonate zoledronate in reducing the risk of first on-study SRE by 17% (median time to first on-study SRE delayed by 8.2 months) and the risk of first and subsequent on-study SREs by 18% across multiple solid tumor types, including some patients with multiple myeloma. Denosumab also improved pain outcomes and reduced the need for strong opioids. Additionally, a phase 3 trial showed denosumab was noninferior to zoledronate in delaying time to first SRE in patients with newly diagnosed multiple myeloma. Denosumab has a convenient 120 mg every 4 weeks recommended dosing schedule with subcutaneous administration. Rare but serious toxicities associated with denosumab include osteonecrosis of the jaw, hypocalcemia, and atypical femoral fracture events, with multiple vertebral fractures reported following treatment discontinuation. After a decade of real-world clinical experience with denosumab, we are still learning about the optimal use and dosing for denosumab. Despite the emergence of novel and effective antitumor therapies, there remains a strong rationale for the clinical utility of antiresorptive therapy for SRE prevention. Ongoing studies aim to optimize clinical management of patients using denosumab for SRE prevention while maintaining safety and efficacy.

    目的:血液病患者与非血液病患者相比,COVID-19的特征很少被分析。我们的目的是分析COVID-19血液学患者与非血液学患者的临床特征和结局是否存在差异。
    方法:在2所大学医院进行回顾性队列研究,纳入SEMICOVID19数据库中的实验室确诊COVID-19患者。将患有基础血液病的队列与年龄和COVID-19日期相匹配的无血液病的对照组进行比较(1:2)。
    结果:纳入了2020年3月至5月的71例病例和142例对照。20人(28.1%)最近接受过化疗。12例(16.9%)为干细胞移植受者(SCT)。11例(15.5%)与COVID-19诊断同时出现中性粒细胞减少。血液病患者出现ARDS(58.5vs20.7%,p=0.0001),血栓性并发症(15.7vs2.1%,p=0.002),DIC(5.7vs0.0%,p=0.011),心力衰竭(14.3vs4.9%,p=0.029)和要求入住ICU(15.5vs2.8%,p=0.001),MV(14.1%对2.1%,p0.001),类固醇(64.8vs33.1%,p=0.0001),托珠单抗(33.8%vs8.5%,p=0.0001)或anakinra治疗(9.9%vs0%,p=0.0001)更频繁。住院死亡率明显更高(38.0%vs18.3%,p=0.002)。
    结论:我们的结果表明,与非血液病患者相比,COVID-19在血液病患者中的预后较差,独立于年龄,ARDS和血栓性并发症的发展导致更高的院内死亡率。
    OBJECTIVE: The characteristics of COVID-19 in haematologic patients compared to non-haematologic patients have seldom been analyzed. Our aim was to analyze whether there are differences in clinical characteristics and outcome of haematologic patients with COVID-19 as compared to non-haematologic.
    METHODS: Retrospective cohort study in 2 University hospitals of patients admitted with laboratory-confirmed COVID-19 included in the SEMICOVID19 database. The cohort with underlying haematologic disease was compared to a cohort of age and date-of-COVID-19-matched controls without haematologic disease (1:2).
    RESULTS: 71 cases and 142 controls were included from March-May 2020.Twenty (28.1%) had received recent chemotherapy. Twelve (16.9%) were stem cell transplant recipients (SCT). Eleven (15.5%) were neutropenic concurrently with COVID-19 diagnosis.Haematologic patients presented ARDS (58.5 vs 20.7%, p = 0.0001), thrombotic complications (15.7 vs 2.1%, p = 0.002), DIC (5.7 vs 0.0%, p = 0.011), heart failure (14.3 vs 4.9%, p = 0.029) and required ICU admission (15.5 vs 2.8%, p = 0.001), MV (14.1% vs 2.1%, p 0.001), steroid (64.8 vs 33.1%, p = 0.0001), tocilizumab (33.8 vs 8.5%, p = 0.0001) or anakinra treatment (9.9% vs 0%, p = 0.0001) more often. In-hospital mortality was significantly higher (38.0% vs 18.3%, p = 0.002).
    CONCLUSIONS: Our results suggest COVID-19 has worse outcomes in haematologic patients than in non-haematologic, independently of age, and that the development of ARDS and thrombotic complications drive the higher in-hospital mortality.

    以蛋白酶体抑制剂为代表的多发性骨髓瘤的新治疗方法,免疫调节药物和单克隆抗体产生了深刻的反响。然而,复发是可能的,所有种类的药物对患者都是难以治疗的。下一代测序提高了我们对与耐药性相关的多发性骨髓瘤基因组的理解,并发现了许多基因组变异。因此,本研究采用新一代全外显子组测序技术,对硼替佐米方案和达雷妥单抗治疗复发和难治性MM患者的耐药相关新变异进行研究.从6例患者的EDTA管中收集外周血样本;其中4例复发且对硼替佐米方案和达拉图单抗无效;两名患者对硼替佐米方案有反应。通过MGI-DNBSEQ-G400仪器进行全外显子组测序。我们在多发性骨髓瘤患者中鉴定出21种变异。在11个基因的复发性和难治性多发性骨髓瘤中发现了17个变异(GNAQ,PMS1,CREB1,NSUNS2,PIK3CG,ROS1,PMS2,FIT4,KDM5A,STK11和ZFHX3)。在4个基因(RAF1,CREB1,ZFHX3和INSR)中对硼替佐米方案有反应的两名患者中发现了四种变异。我们已经观察到许多基因中的几种遗传变异,这些基因可能与这些患者的不良预后和对治疗的不良反应有关。这些值应该在使用RNA-seq技术鉴定基因组表达的大样本研究中进一步证实。
    Novel treatment in multiple myeloma represented by proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies have produced a deep response. However, relapses are possible, and all classes of drugs are refractory to patients. Next-generation sequencing has improved our understanding of the multiple myeloma genome related to drug resistance and has discovered many genomic variants. Therefore, this study was conducted to investigate new variants associated with drug resistance in MM patients who relapsed and refractory to bortezomib regimen and daratumumab treatment using next-generation sequencing for whole-exome sequencing. Peripheral blood samples were collected in EDTA tubes from six patients; four were in relapsed and refractory to bortezomib regimens and daratumumab; two patients responded to bortezomib regimens. Whole-exome sequencing was performed by the MGI-DNBSEQ-G400 instrument. We identified 21 variants in multiple myeloma patients. Seventeen variants were found in relapsed and refractory multiple myeloma in 11 genes (GNAQ, PMS1, CREB1, NSUNS2, PIK3CG, ROS1, PMS2, FIT4, KDM5A, STK11 and ZFHX3). And four variants were identified in two patients with response to bortezomib regimens in 4 genes (RAF1, CREB1, ZFHX3 and INSR). We have observed several genetic variants in many genes that may have been associated with the poor prognosis and poor response to treatment in these patients. These values should be further confirmed in large sample studies using the RNA-seq technique to identify genome expression.

    免疫球蛋白轻链(AL)淀粉样变性是一种无法治愈的浆细胞疾病,其特征是错误折叠的免疫球蛋白游离轻链(FLC)的原纤维在靶器官中沉积,导致失败。心脏受累在AL淀粉样变性中很常见,并且是最不利的预后特征。具有快速组织诊断和组合开始的高临床怀疑指数,高效的细胞减灭剂治疗对于阻止淀粉样蛋白沉积过程和保持器官功能至关重要。分子靶向药物的临床使用,如蛋白酶体抑制剂和免疫调节剂,单克隆抗体,如daratumumab,对符合条件的患者进行风险调整后的自体干细胞移植,从根本上改变了AL淀粉样变性的自然史。这里,我们回顾了AL淀粉样变性最先进的治疗方案,着眼于未来的治疗场所,以影响这一毁灭性疾病的结局.
    Immunoglobulin light chain (AL) amyloidosis is an incurable plasma cell disorder characterized by deposition of fibrils of misfolded immunoglobulin free light chains (FLC) in target organs, leading to failure. Cardiac involvement is common in AL amyloidosis and represents the single most adverse prognostic feature. A high index of clinical suspicion with rapid tissue diagnosis and commencement of combinatorial, highly effective cytoreductive therapy is crucial to arrest the process of amyloid deposition and preserve organ function. The clinical use of molecularly targeted drugs, such as proteasome inhibitors and immunomodulatory agents, monoclonal antibodies such as daratumumab, and risk-adjusted autologous stem cell transplant in eligible patients, has radically changed the natural history of AL amyloidosis. Here, we review the state-of-the-art treatment landscape in AL amyloidosis with an eye toward future therapeutic venues to impact the outcome of this devastating illness.

    在过去的二十年中,各种含硼药物已被批准用于临床。更多的人目前正在临床试验中。对含硼化合物的兴趣日益增加是由于其与生物靶标的独特结合特性;例如,硼取代可用于调节生物活性,药代动力学特性,和抗药性。从这个角度来看,我们旨在全面回顾硼化合物在药物发现中的现状,特别关注2015年至2020年12月的进展。我们将这些化合物分为显示抗癌的组,抗菌,抗病毒,抗寄生虫和其他活动,并讨论与每个活动相关的生物目标,以及潜在的未来发展。
    Various boron-containing drugs have been approved for clinical use over the past two decades, and more are currently in clinical trials. The increasing interest in boron-containing compounds is due to their unique binding properties to biological targets; for example, boron substitution can be used to modulate biological activity, pharmacokinetic properties, and drug resistance. In this perspective, we aim to comprehensively review the current status of boron compounds in drug discovery, focusing especially on progress from 2015 to December 2020. We classify these compounds into groups showing anticancer, antibacterial, antiviral, antiparasitic and other activities, and discuss the biological targets associated with each activity, as well as potential future developments.
