    背景:先前的研究表明,新辅助化疗(NAC)中添加铂类药物可改善三阴性乳腺癌(TNBC)患者的预后。然而,尚无研究评估紫杉烷和洛铂联合用药的疗效和安全性.在这项研究中,我们进行了一项随机对照II期临床研究,以比较紫杉烷联合洛铂或蒽环类药物的疗效和安全性.
    方法:我们将I-III期TNBC患者随机分为A组和B组。B组接受了六个周期的紫杉烷与蒽环类和环磷酰胺(TEC)的组合,或八个周期的蒽环类和环磷酰胺的组合,并连续使用紫杉烷(EC-T)。两个手臂都在NAC后接受了手术。主要终点是病理完全缓解(pCR)。次要终点是无事件生存期(EFS),总生存期(OS),和安全。
    结果:共评估了103例患者(A组51例,B组52例)。A臂的pCR率明显高于B臂(41.2%vs.21.2%,P=0.028)。淋巴结阳性和中性粒细胞与淋巴细胞比率(NLR)低的患者比淋巴结阴性和NLR高的患者从A组中受益更多(分别为P交互作用=0.001,P交互作用=0.012)。两组之间的EFS(P=0.895)或OS(P=0.633)没有显着差异。A组3/4级贫血患病率较高(P=0.015),B组3/4级中性粒细胞减少症患病率较高(P=0.044).
    结论:新佐剂紫杉烷联合洛铂的疗效优于紫杉烷联合蒽环类,两种方案的毒性特征相似.该试验可能为今后NAC治疗TNBC的更好的联合免疫治疗策略提供参考。
    BACKGROUND: Previous studies have shown that the addition of platinum to neoadjuvant chemotherapy (NAC) improved outcomes for patients with triple-negative breast cancer (TNBC). However, no studies have assessed the efficacy and safety of the combination of taxane and lobaplatin. In this study, we conducted a randomized controlled phase II clinical study to compare the efficacy and safety of taxane combined with lobaplatin or anthracycline.
    METHODS: We randomly allocated patients with stage I-III TNBC into Arm A and Arm B. Arm A received six cycles of taxane combined with lobaplatin (TL). Arm B received six cycles of taxane combined with anthracycline and cyclophosphamide (TEC) or eight cycles of anthracycline combined with cyclophosphamide and sequential use of taxane (EC-T). Both Arms underwent surgery after NAC. The primary endpoint was the pathologic complete response (pCR). Secondary endpoints were event-free survival (EFS), overall survival (OS), and safety.
    RESULTS: A total of 103 patients (51 in Arm A and 52 in Arm B) were assessed. The pCR rate of Arm A was significantly higher than that of Arm B (41.2% vs. 21.2%, P = 0.028). Patients with positive lymph nodes and low neutrophil-to-lymphocyte ratio (NLR) benefited significantly more from Arm A than those with negative lymph nodes and high NLR (Pinteraction = 0.001, Pinteraction = 0.012, respectively). There was no significant difference in EFS (P = 0.895) or OS (P = 0.633) between the two arms. The prevalence of grade-3/4 anemia was higher in Arm A (P = 0.015), and the prevalence of grade-3/4 neutropenia was higher in Arm B (P = 0.044).
    CONCLUSIONS: Neoadjuvant taxane plus lobaplatin has shown better efficacy than taxane plus anthracycline, and both regimens have similar toxicity profiles. This trial may provide a reference for a better combination strategy of immunotherapy in NAC for TNBC in the future.

    背景:弥漫性大B细胞淋巴瘤(DLBCL)患者通常由于蒽环类化疗引起的心脏损害而预后不良,左心室舒张功能障碍早期表现。矢量流映射(VFM)是一种新颖的技术,其检测蒽环类化疗后左心室舒张功能障碍的有效性仍未得到证实。
    目的:本研究使用向量流图(VFM)评估DLBCL患者蒽环类化疗后的左心室舒张功能。
    方法:我们前瞻性纳入54例接受蒽环类化疗(至少4个周期)的DLBCL患者作为病例组,54例年龄和性别匹配的个体作为对照。在化疗前(T0)进行病例组VFM评估,4个化疗周期后(T4),在对照组中。测量包括基础,中间,和顶端段能量损失(ELb,ELm,ELa)和心室内压差(IVPDb,IVPDm,IVPDa)跨越四个舒张期:等容舒张(D1),快速填充(D2),缓慢填充(D3),和心房收缩(D4)。
    结果:在T0时比较对照组和病例组之间的参数时,在一般数据中没有观察到显着差异,常规超声参数,和VFM参数(均P>0.05)。从T0到T4,ELa在整个舒张周期中显著增加(所有P<0.05);ELm仅在D4期间增加(所有P<0.05);ELb在D1、D2和D4期间增加(所有P<0.05)。所有IVPD测量(IVPDa,IVPDm,IVPDb)在D1和D4期间增加(均P<0.05),但在D2和D3期间减少(均P<0.05)。ELa-D4、IVPDa-D4和参数A之间存在显著正相关,e\',E/E,\'和LAVI(均r>0.5,均P<0.001)。ELa-D4IVPDa-D4与E/A呈负相关(均r<-0.5,均P<0.001)。观察到IVPDa-D1,IVPDa-D2与E,E/E\',和LAVI(0.3结论:VFM参数与常规舒张功能参数有一定的相关性,在评估左心室舒张功能方面有前景。此外,VFM参数对早期舒张功能变化表现出更大的敏感性,提示VFM可作为评价DLBCL患者化疗前后左心室舒张功能差异的新方法。
    BACKGROUND: Patients with diffuse large B-cell lymphoma (DLBCL) often experience a poor prognosis due to cardiac damage induced by anthracycline chemotherapy, with left ventricular diastolic dysfunction manifesting early. Vector Flow Mapping (VFM) is a novel technology, and its effectiveness in detecting left ventricular diastolic dysfunction following anthracycline chemotherapy remains unverified.
    OBJECTIVE: This study evaluates left ventricular diastolic function in DLBCL patients after anthracycline chemotherapy using vector flow mapping (VFM).
    METHODS: We prospectively enrolled 54 DLBCL patients who had undergone anthracycline chemotherapy (receiving a minimum of 4 cycles) as the case group and 54 age- and sex-matched individuals as controls. VFM assessments were conducted in the case group pre-chemotherapy (T0), post-4 chemotherapy cycles (T4), and in the control group. Measurements included basal, middle, and apical segment energy loss (ELb, ELm, ELa) and intraventricular pressure differences (IVPDb, IVPDm, IVPDa) across four diastolic phases: isovolumic relaxation (D1), rapid filling (D2), slow filling (D3), and atrial contraction (D4).
    RESULTS: When comparing parameters between the control and case groups at T0, no significant differences were observed in general data, conventional ultrasound parameters, and VFM parameters (all P > 0.05). From T0 to T4, ELa significantly increased throughout the diastole cycle (all P < 0.05); ELm increased only during D4 (all P < 0.05); and ELb increased during D1, D2, and D4 (all P < 0.05). All IVPD measurements (IVPDa, IVPDm, IVPDb) increased during D1 and D4 (all P < 0.05) but decreased during D2 and D3 (all P < 0.05). Significant positive correlations were identified between ELa-D4, IVPDa-D4, and parameters A, e\', E/e,\' and LAVI (all r > 0.5, all P < 0.001). Negative correlations were noted with E/A for ELa- D4 IVPDa-D4 (all r < -0.5, all P < 0.001). Positive correlations were observed for IVPDa-D1, IVPDa-D2 with E, E/e\', and LAVI (0.3CONCLUSIONS: VFM parameters demonstrate a certain correlation with conventional diastolic function parameters and show promise in assessing left ventricular diastolic function. Furthermore, VFM parameters exhibit greater sensitivity to early diastolic function changes, suggesting that VFM could be a novel method for evaluating differences in left ventricular diastolic function in DLBCL patients before and after chemotherapy.

    蒽环类化疗药物的疗效,其中包括阿霉素及其结构亲属柔红霉素和伊达比星,在肿瘤学上几乎是无与伦比的,尽管副作用包括累积剂量依赖性心脏毒性,治疗相关的恶性肿瘤和不孕症。解毒蒽环类药物,同时保留其抗肿瘤作用,可以说是现代肿瘤学中未满足的主要需求。在这项研究中,限制抗癌治疗的心血管并发症是导致美国1700万癌症幸存者发病和死亡的主要原因,我们检查了不同的临床相关蒽环类药物的一系列特征,包括作用模式(染色质和DNA损伤),生物分布,临床前模型和患者的抗肿瘤疗效和心脏毒性。不同的蒽环类药物具有令人惊讶的个体功效和毒性特征。特别是,阿克拉霉素在临床前模型和临床研究中脱颖而出,因为它能有效地杀死癌细胞,缺乏心脏毒性,即使达到阿霉素或伊达比星的最大累积剂量,也可以安全地给药。回顾性分析阿克拉霉素作为二线治疗复发/难治性AML患者的生存效果与一线治疗相似,与其他强化化疗相比,5年总生存率显著提高23%。考虑到单个蒽环类药物作为不同的实体,揭示了新的治疗选择,例如阿克拉比星的鉴定,显著改善AML患者的生存结局,同时减轻治疗限制性副作用.在这些发现的基础上,准备了一项国际多中心III期前瞻性研究,将阿克拉霉素整合到复发/难治性AML患者的治疗中。
    The efficacy of anthracycline-based chemotherapeutics, which include doxorubicin and its structural relatives daunorubicin and idarubicin, remains almost unmatched in oncology, despite a side effect profile including cumulative dose-dependent cardiotoxicity, therapy-related malignancies and infertility. Detoxifying anthracyclines while preserving their anti-neoplastic effects is arguably a major unmet need in modern oncology, as cardiovascular complications that limit anti-cancer treatment are a leading cause of morbidity and mortality among the 17 million cancer survivors in the U.S. In this study, we examined different clinically relevant anthracycline drugs for a series of features including mode of action (chromatin and DNA damage), bio-distribution, anti-tumor efficacy and cardiotoxicity in pre-clinical models and patients. The different anthracycline drugs have surprisingly individual efficacy and toxicity profiles. In particular, aclarubicin stands out in pre-clinical models and clinical studies, as it potently kills cancer cells, lacks cardiotoxicity, and can be safely administered even after the maximum cumulative dose of either doxorubicin or idarubicin has been reached. Retrospective analysis of aclarubicin used as second-line treatment for relapsed/refractory AML patients showed survival effects similar to its use in first line, leading to a notable 23% increase in 5-year overall survival compared to other intensive chemotherapies. Considering individual anthracyclines as distinct entities unveils new treatment options, such as the identification of aclarubicin, which significantly improves the survival outcomes of AML patients while mitigating the treatment-limiting side-effects. Building upon these findings, an international multicenter Phase III prospective study is prepared, to integrate aclarubicin into the treatment of relapsed/refractory AML patients.

    目的:参麦注射液是一种经典的中药方剂,通常被推荐用于治疗蒽环类药物引起的心脏毒性。然而,参麦注射液治疗蒽环类药物引起的心脏毒性的疗效和安全性尚未见报道.
    方法:我们对8个文献数据库和2个临床试验注册中心进行了全面检索,检索自数据库建立至2023年7月1日与参麦注射液治疗蒽环类药物所致心脏毒性相关的所有随机对照试验(RCT).使用RStudio和RevMan5.4中的Meta软件包进行数据分析。GRADEpro3.6.1软件用于评估证据质量。
    结果:本研究共纳入16项RCTs,包括2140例患者。Meta分析显示,参麦注射液改善ST-T段改变具有优势(RR=0.28;95%CI,0.20~0.39;P<0.0001)(P<0.01),肌酸激酶同工酶(SMD=-3.49;95%CI,-5.24至-1.74;P<0.0001),延长QT间期(RR=0.46;95%CI,0.28~0.75;P=0.0018),QRS电压低(RR=0.44;95%CI,0.27至0.71;P=0.0007),窦性心动过速(RR=0.41;95%CI,0.28~0.60;P<0.0001),房性早搏(RR=0.55;95%CI,0.35~0.87;P=0.01),蒽环类药物引起的心脏毒性患者的室性早搏(RR=0.39;95%CI,0.26至0.59;P<0.0001)和肌酸激酶(SMD=-1.43;95%CI,-2.57至-0.29;P<0.0001)。优势,这得到了敏感性分析的支持,但不能改善左心室射血分数(MD=16.01;95%CI,-3.10至35.12;P=0.10)和房室传导阻滞(RR=0.49;95%CI,0.24至1.03;P=0.06)。纳入研究的文献未提及参麦注射液安全性方面的数据,所以我们还不知道参麦注射液的安全性。亚组分析结果表明异质性与给药剂量和化疗方案无关。发表偏倚测试表明没有发表偏倚。结果的证据质量从“非常低”到“中等”不等。\"
    结论:本研究提示参麦注射液可有效治疗蒽环类所致心脏毒性,是治疗蒽环类所致心脏毒性的潜在药物。然而,由于纳入RCT的方法学质量差,我们建议严格,高品质,大样本试验来证实我们的发现。
    OBJECTIVE: Shenmai injection is a classic herbal prescription, and is often recommended for the treatment of anthracycline-induced cardiotoxicity. However, the efficacy and safety of Shenmai injection for the treatment of anthracycline-induced cardiotoxicity have not been reported.
    METHODS: We conducted a comprehensive search of eight literature databases and two clinical trial registries, retrieving all randomized controlled trials (RCTs) related to the treatment of anthracycline-induced cardiotoxicity with Shenmai injection from the establishment of the databases to July 1, 2023. Data analysis was performed using the Meta package in RStudio and RevMan 5.4. The GRADE pro3.6.1 software was utilized for assessing the quality of evidence.
    RESULTS: A total of 16 RCTs including 2140 patients were included in this study. Meta-analysis showed that Shenmai injection had an advantage in improving ST-T segment changes (RR = 0.28; 95 % CI, 0.20 to 0.39; P < 0.0001) (P < 0.01), creatine kinase isoenzyme (SMD = -3.49; 95 % CI, -5.24 to -1.74; P < 0.0001), Prolonged QT interval (RR = 0.46; 95 % CI, 0.28 to 0.75; P = 0.0018), Low QRS Voltage (RR = 0.44; 95 % CI, 0.27 to 0.71; P = 0.0007), sinus tachycardia (RR = 0.41; 95 % CI, 0.28 to 0.60; P < 0.0001), atrial premature beats (RR = 0.55; 95 % CI, 0.35 to 0.87; P = 0.01), Premature Ventricular Contractions (RR = 0.39; 95 % CI, 0.26 to 0.59; P < 0.0001) and creatine kinase (SMD = -1.43; 95 % CI, -2.57 to -0.29; P < 0.0001) in patients with anthracycline-induced cardiotoxicity. advantage, which was supported by sensitivity analyses, but not in improving left ventricular ejection fraction (MD = 16.01; 95 % CI, -3.10 to 35.12; P = 0.10) and atrioventricular block (RR = 0.49; 95 % CI, 0.24 to 1.03; P = 0.06). The literature included in the study did not refer to data regarding the safety aspects of Shenmai injection, so we do not yet know the safety of Shenmai injection. The results of subgroup analyses suggested that heterogeneity was not related to the administered dose and chemotherapy regimen. The publication bias test showed no publication bias. The quality of evidence for the results ranged from \"very low\" to \"moderate.\"
    CONCLUSIONS: This study suggests that Shenmai injection is effective in treating anthracycline-induced cardiotoxicity and is a potential treatment for anthracycline-induced cardiotoxicity. However, due to the poor methodological quality of the included RCTs, we recommend rigorous, high-quality, large-sample trials to confirm our findings.

    蒽环类药物化疗可引起心脏毒性,可能导致一些癌症患者停止治疗。在心脏肿瘤研究中,预防和减少蒽环类抗生素引起的心脏毒性(AIC)是一个热点问题。对于AIC的治疗,calycosin(CA),黄芪(AR)中的异黄酮成分,已成为研究热点。然而,calycosin治疗AIC的详细机制仍未揭示。
    从网络药理学的多个维度探讨CA对AIC的影响,分子对接,和实验评估。
    该研究使用网络药理学和分子对接评估了calycosin治疗AIC的潜在靶标和机制。使用在线可用的数据库筛选CA和AIC的候选基因/靶标。使用STRING平台构建了常见靶标之间的蛋白质-蛋白质相互作用(PPI),然后使用Cytoscape可视化结果。使用分子对接来评估CA与常见靶标之间的结合力的强度。通过途径富集和GSEA解释了CA的可能药理机制。随后,在体外实验中确定了候选靶标。
    网络药理学有效地发现了CA在AIC中的多目标干预,包括TNF,ABCC1,TOP2A,ABCB1和XDH。根据分子对接分析,与ATP结合盒亚家族B成员1(ABCB1)结合的CA具有最高的结合能(〜7.5kcal/mol),并且被选择并可视化用于后续分析。体外实验表明,与DMSO对照实验相比,ABCB1在不同剂量的阿霉素(DOX)下表现出明显的时间曲线变化。通过强调氧化应激(OR)和炎症的生物学过程,揭示了CA的抗AIC药理机制。
    我们采用了一种可行的生物信息学方法来连接网络和分子对接,以确定calycosin对AIC的治疗机制,并在体外实验中确定了一些生物信息学结果。提出的结果表明,CA可能代表AIC的令人鼓舞的治疗方法。
    UNASSIGNED: Chemotherapy with anthracyclines can cause cardiotoxicity, possibly leading to stopping treatment in some cancer patients. In cardio-oncology research, preventing and minimizing anthracycline-induced cardiotoxicity (AIC) is a hot issue. For the treatment of AIC, calycosin (CA), an isoflavone component in astragali radix (AR), has become a research focus. However, the elaborate mechanisms of calycosin treating AIC remain to be unrevealed.
    UNASSIGNED: To explore the effects of CA on AIC through multiple dimensions concerning network pharmacology, molecular docking, and experimental evaluations.
    UNASSIGNED: The study evaluated calycosin\'s potential targets and mechanisms for treating AIC using network pharmacology and molecular docking. The candidate genes/targets of CA and AIC were screened using the online-available database. Protein-protein interactions (PPI) between the common targets were constructed using the STRING platform, and the results were then visualized using Cytoscape. Molecular docking was used to evaluate the strength of the binding force between CA and the common targets. The possible pharmacological mechanisms of CA were explained by pathway enrichment and GSEA. Subsequently, the candidate targets were identified in vitro experiments.
    UNASSIGNED: Network pharmacology effectively discovered the CA\'s multitarget intervention in AIC, including TNF, ABCC1, TOP2A, ABCB1, and XDH. CA binds to the ATP-binding cassette subfamily B member 1(ABCB1) had the highest binding energy (-7.5 kcal/mol) according to the molecular docking analysis and was selected and visualized for subsequent analysis. In vitro experiments showed that ABCB1 exhibited significant time-curve changes under different doses of doxorubicin (DOX) compared with DMSO control experiments. The anti-AIC pharmacological mechanism of CA were revealed by highlighting the biological processes of oxidative stress (OR) and inflammation.
    UNASSIGNED: We employed a practicable bioinformatics method to connect network and molecular docking to determine the calycosin\'s therapeutic mechanism against AIC and identified some bioinformatics results in in vitro experiments. The results presented show that CA may represent an encouraging treatment for AIC.

    背景:目前的指南已推荐诊断蒽环类药物引起的心脏毒性的左心室整体纵向应变(LVGLS)。然而,对该人群中左心房(LA)形态和功能的早期变化知之甚少.我们的研究旨在通过三维超声心动图(3DE)评估LA指标及其对LVGLS的潜在有用性,以早期发现接受蒽环类药物的淋巴瘤患者的亚临床心脏毒性。
    方法:共80例弥漫性大B细胞淋巴瘤患者接受6个周期的蒽环类药物治疗。在基线(T0)进行超声心动图检查,在四个周期(T1)之后,化疗完成6个周期后(T2)。左心室射血分数(LVEF),LVGLS,洛杉矶卷,洛杉矶排空分数(LAEF),洛杉矶主动排空分数(LAAEF),用3DE量化LA储层纵向应变(LASr)。左房室整体纵向应变(LAVGLS)计算为LASr峰值和LVGLS峰值的绝对值之和(LAVGLS=LASr+|LVGLS|)。LV心脏毒性定义为新的LVEF降低≥10个百分点至LVEF≤50%。
    结果:14例(17.5%)患者在T2时出现左心室心脏毒性。洛杉矶卷,LAEF,随着时间的推移,LAAEF保持稳定。LASr减值(28.35±5.03与25.04±4.10,p<.001),LVGLS(-22.77±2.45vs.-20.44±2.62,p<.001),和LAVGLS(51.12±5.63vs.在化疗的第四周期(T1)结束时观察到45.61±5.22,p<.001)。LVEF的统计学显着下降(61.30±4.73vs.57.08±5.83,p<.001)仅在T2时观察到。LASr的相对减少(ΔLASr),LVGLS(ΔLVGLS),从T0到T1的LAVGLS(ΔLAVGLS)是LV心脏毒性的预测因子。ΔLASr>19.75%(灵敏度,71.4%;特异性,87.9%;曲线下面积(AUC),.842;p<.001),aΔLVGLS>13.19%(灵敏度,78.6%;特异性,74.2%;AUC,.763;p<.001),ΔLAVGLS>16.80%(灵敏度,78.6%;特异性,93.9%;AUC,.905;p<.001)预测了T2时随后的LV心脏毒性,ΔLAVGLS的AUC显着大于ΔLVGLS的AUC(.905vs..763,p=.027)。与ΔLVGLS相比,ΔLAVGLS显示出改善的特异性(93.9%vs.74.2%,p=.002)并保持预测LV心脏毒性的敏感性。
    结论:LASr可以预测蒽环类药物诱导的LV心脏毒性,具有良好的诊断性能。将LASr并入LVGLS(LAVGLS)导致在预测LV心脏毒性方面显著提高的特异性和维持的敏感性。
    BACKGROUND: Left ventricular global longitudinal strain (LVGLS) has been recommended by current guidelines for diagnosing anthracycline-induced cardiotoxicity. However, little is known about the early changes in left atrial (LA) morphology and function in this population. Our study aimed to evaluate the potential usefulness of LA indices and their incremental value to LVGLS with three-dimensional echocardiography (3DE) in the early detection of subclinical cardiotoxicity in patients with lymphoma receiving anthracycline.
    METHODS: A total of 80 patients with diffuse large B-cell lymphoma who received six cycles of anthracycline-based treatment were enrolled. Echocardiography was performed at baseline (T0), after four cycles (T1), and after the completion of six cycles of chemotherapy (T2). Left ventricular ejection fraction (LVEF), LVGLS, LA volumes, LA emptying fraction (LAEF), LA active emptying fraction (LAAEF), and LA reservoir longitudinal strain (LASr) were quantified with 3DE. Left atrioventricular global longitudinal strain (LAVGLS) was calculated as the sum of peak LASr and the absolute value of peak LVGLS (LAVGLS = LASr+|LVGLS|). LV cardiotoxicity was defined as a new LVEF reduction by ≥10 percentage points to an LVEF of ≤50%.
    RESULTS: Fourteen (17.5%) patients developed LV cardiotoxicity at T2. LA volumes, LAEF, and LAAEF remained stable over time. Impairment of LASr (28.35 ± 5.03 vs. 25.04 ± 4.10, p < .001), LVGLS (-22.77 ± 2.45 vs. -20.44 ± 2.62, p < .001), and LAVGLS (51.12 ± 5.63 vs. 45.61 ± 5.22, p < .001) was observed by the end of the fourth cycle of chemotherapy (T1). Statistically significant declines in LVEF (61.30 ± 4.73 vs. 57.08 ± 5.83, p < .001) were only observed at T2. The relative decrease in LASr (ΔLASr), LVGLS (ΔLVGLS), and LAVGLS (ΔLAVGLS) from T0 to T1 were predictors of LV cardiotoxicity. A ΔLASr of >19.75% (sensitivity, 71.4%; specificity, 87.9%; area under the curve (AUC), .842; p < .001), a ΔLVGLS of >13.19% (sensitivity, 78.6%; specificity, 74.2%; AUC, .763; p < .001), and a ΔLAVGLS of >16.80% (sensitivity, 78.6%; specificity, 93.9%; AUC, .905; p < .001) predicted subsequent LV cardiotoxicity at T2, with the AUC of ΔLAVGLS significantly larger than that of ΔLVGLS (.905 vs. .763, p = .027). Compared to ΔLVGLS, ΔLAVGLS showed improved specificity (93.9% vs. 74.2%, p = .002) and maintained sensitivity in predicting LV cardiotoxicity.
    CONCLUSIONS: LASr could predict anthracycline-induced LV cardiotoxicity with excellent diagnostic performance. Incorporating LASr into LVGLS (LAVGLS) led to a significantly improved specificity and maintained sensitivity in predicting LV cardiotoxicity.

    蒽环类药物是几种癌症的最基本和最重要的治疗方法,尤其是淋巴瘤和乳腺癌。然而,它们的使用受到剂量依赖性心脏毒性的限制,这种心脏毒性可能在蒽环类药物开始时或在治疗终止后数年出现.全面了解蒽环类药物诱导的心脏毒性机制,尚未实现,目前正在努力,对于开发有效的预防心脏毒性的方法至关重要,以及早期发现和治疗它。因此,我们综述了蒽环类药物引起心脏毒性的机制的最新进展,以及监测和预防这一问题的方法。
    Anthracyclines are the most fundamental and important treatment of several cancers especially for lymphoma and breast cancer. However, their use is limited by a dose-dependent cardiotoxicity which may emerge early at the initiation of anthracycline administration or several years after termination of the therapy. A full comprehending of the mechanisms of anthracycline-induced cardiotoxicity, which has not been achieved and is currently under the efforts, is critical to the advance of developing effective methods to protect against the cardiotoxicity, as well as to early detect and treat it. Therefore, we review the recent progress of the mechanism underlying anthracycline-induced cardiotoxicity, as well as approaches to monitor and prevent this issue.

    背景:目前急性白血病的治疗基于蒽环类化疗。蒽环类药物,尽管提高了患者的生存率,有严重的心脏毒性,因此心脏监测应优先考虑。目的探讨急性白血病患者蒽环类药物诱发亚临床心脏毒性(AISC)的可能早期预测因子。
    方法:我们进行了一项前瞻性观察性研究,涉及51例接受蒽环类药物治疗的急性白血病患者。人口统计数据,临床变量,在基线和化疗3个周期后收集超声心动图变量和生化变量。根据整体纵向峰值收缩期应变的变化将患者分为AISC组和No-AISC组。使用回归模型和受试者工作特征曲线分析来探索变量与AISC之间的关系。
    结果:17名患者在3个周期的蒽环类药物治疗后出现亚临床心脏毒性。多因素logistic回归分析显示DBil呈显著相关(OR0.612,95%CI0.409-0.916,p=0.017),TBil(OR0.841,95%CI0.717-0.986,p=0.033),随着AISC的发展,PLT(OR1.012,95%CI1.002-1.021,p=0.016)和Glu(OR1.873,95%CI1.009-3.475,p=0.047)。化疗3个周期后,AISC组和NO-AISC组之间的PLT存在显着差异。此外,AISC组和NO-AISC组从基线到化疗3个周期后PLT的动态变化均有统计学意义.PLT和N末端B型利钠肽前体(NT-proBNP)联合诊断AISC的曲线下面积(AUC)比单独使用PLT和NT-proBNP最高(AUC=0.713,95CI:0.56-0.87,P=0.017)。
    结论:总胆红素(TBil),直接胆红素(DBil),血小板(PLT)和血糖(Glu)是接受蒽环类药物治疗的急性白血病患者AISC的独立影响因素。胆红素可能是AISC的保护因素,PLT可能是AISC的促成因素。基线PLT和基线NT-proBNP联合对接受3个周期化疗的急性白血病患者AISC显示出令人满意的预测能力。
    BACKGROUND: Current treatment of acute leukemia is based on anthracycline chemotherapy. Anthracyclines, despite improving patient survival, have serious cardiotoxicity and therefore cardiac monitoring should be a priority. The purpose of this study is to explore the possible early predictors of anthracycline-induced subclinical cardiotoxicity(AISC)in acute leukemia patients.
    METHODS: We conducted a prospective observational study involving 51 patients with acute leukemia treated with anthracycline. Demographic data, clinical variables, echocardiography variables and biochemical variables were collected at baseline and after 3 cycles of chemotherapy. Patients were divided into the AISC and No-AISC groups according to changes of global longitudinal peak systolic strain. Regression models and receiver operating characteristic curve analysis were used to explore the relationship between the variables and AISC.
    RESULTS: 17 of the patients suffered subclinical cardiotoxicity after 3 cycles of anthracycline treatment. Multiple logistic regression analysis showed a significant association of DBil (OR 0.612, 95% CI 0.409-0.916, p = 0.017), TBil (OR 0.841, 95% CI 0.717-0.986, p = 0.033), PLT (OR 1.012, 95% CI 1.002-1.021, p = 0.016) and Glu (OR 1.873, 95% CI 1.009-3.475, p = 0.047) with the development of AISC. After 3 cycles of chemotherapy, there was a significant difference in PLT between the AISC and NO-AISC groups. Moreover, the dynamic changes in PLT from baseline to after 3 cycles of chemotherapy were each statistically significant in the AISC and NO-AISC groups. The combination of PLT and N-terminal pro-B-type natriuretic peptide (NT-proBNP) had the highest area under curves (AUC) for the diagnosis of AISC than PLT and NT-proBNP alone (AUC = 0.713, 95%CI: 0.56-0.87, P = 0.017).
    CONCLUSIONS: Total bilirubin (TBil), direct bilirubin (DBil), platelets (PLT) and blood glucose (Glu) are independent influencing factors for AISC in acute leukemia patients receiving anthracycline therapy. Bilirubin may be a protective factor and PLT may be a contributing factor for AISC. The combination of baseline PLT and baseline NT-proBNP shows satisfactory predictive ability for AISC in acute leukemia cases treated with 3 cycles of chemotherapy.

    蒽环类(ANT)药物广泛用于恶性肿瘤患者,可以显着延长患者的无病生存率。随着其临床应用越来越普遍,关于因ANT治疗而导致严重心脏毒性的信息正逐渐被人们所了解.然而,据我们所知,由于使用ANT引起的迟发性心脏毒性尚未得到充分研究。本报告描述了一名36岁的男性患者,他向贵谦国际总医院(贵阳,中国)最近10天内有呼吸困难的主诉。显著升高的B型利钠肽水平和超声心动图显示整个心脏增大,该患者认为严重的心力衰竭是他症状的原因。然而,这种潜在心力衰竭的原因并不明显,直到患者被问及他的癌症治疗史。在咨询以评估终末期心力衰竭的评估后,目前只能提供抗心衰治疗和对症治疗。本报告描述了这种情况,并回顾了现有文献,为ANT治疗后迟发性心力衰竭患者的诊断和治疗提供了依据。
    Anthracyclic (ANT) drugs are widely used for patients with malignant tumors and can markedly prolong the disease-free survival rate of patients. As its clinical application becomes more common, information regarding serious cardiotoxicity as a result of ANT treatment is becoming understood. However, to the best of our knowledge, delayed-onset cardiotoxicity due to ANT use has not been studied sufficiently. The present report describes a 36-year-old male patient who presented to Guiqian International General Hospital (Guiyang, China) with a complaint of dyspnea in the last 10 days. Substantially elevated B-type natriuretic peptide levels and echocardiography showing enlargement of the entire heart, of the patient suggested that severe heart failure was the cause of his symptoms. However, the cause of this potential heart failure was not apparent until the patient was questioned about his cancer treatment history. Following consultation to evaluate the assessment of end-stage heart failure, currently only anti-heart failure treatment and symptomatic treatment can be provided. The present report describes this case and reviews the existing literature to provide a basis for the diagnosis and treatment of patients with delayed-onset heart failure following ANT treatment.

    对于人类表皮生长因子受体2(HER2)阳性乳腺癌患者的新辅助治疗的标准推荐是曲妥珠单抗联合化疗,但目前尚无合适化疗方案的标准推荐.这项荟萃分析评估了同时使用抗HER2靶向药物和基于蒽环类的新辅助化疗(NAC)治疗HER2阳性乳腺癌的疗效和心脏安全性。
    病理完全缓解(pCR)的合并比值比(OR)率,总生存期(OS)的合并风险比(HR),计算左心室射血分数(LVEF)下降事件。功效差异,预后,比较了接受含蒽环类药物方案(AB)和接受非蒽环类药物(nAB)NAC治疗的患者的心脏安全性.
    在4个前瞻性研究和3个回顾性研究中,共有1366名患者被纳入荟萃分析。pCR率的合并OR为0.73,95%置信区间(CI)为0.43至1.24(P=.246)。低肿瘤负荷病例的亚组分析显示,与nAB相比,AB组患者的pCR率没有改善,合并OR率为0.73,95%CI为0.37至1.44(P=0.357)。AB组和nAB组的3年OS率分别为95.63%和95.54%,分别,无统计学差异(P=0.157)。与nAB组的13.33%相比,AB组的LVEF下降率显著增加19.07%,HR为1.62,95%CI为1.11至2.36(P=0.013)。
    添加蒽环类药物并没有提高新辅助治疗后的pCR率和生存率,蒽环类药物的心脏毒性增加进一步限制了它们的应用。这项研究表明,在HER2阳性乳腺癌患者的新辅助治疗中使用不含蒽环类药物的抗HER2药物是可行的。
    UNASSIGNED: The standard recommendation for neoadjuvant therapy for human epidermal growth factor receptor-2 (HER2)-positive breast cancer patients is trastuzumab in combination with chemotherapy, but there is no current standard recommendation for appropriate chemotherapy regimens. This meta-analysis evaluated the efficacy and cardiac safety of the concurrent use of anti-HER2 targeted drugs and anthracycline-based neoadjuvant chemotherapy (NAC) for HER2-positive breast cancers.
    UNASSIGNED: The pooled odds ratio (OR) rate for pathologic complete response (pCR), the pooled hazard ratio (HR) of overall survival (OS), and the left ventricular ejection fraction (LVEF) decline events were all calculated. Differences in efficacy, prognosis, and cardiac safety were compared between patients receiving an anthracycline-containing regimen (AB) and those treated with non-anthracycline-based (nAB) NAC.
    UNASSIGNED: A total of 1366 patients in 4 prospective and 3 retrospective studies were included in the meta-analysis. The pooled OR for pCR rate was 0.73 with a 95% confidence interval (CI) of 0.43 to 1.24 (P = .246). Subgroup analysis of low tumor burden cases showed no improvement in pCR rate for patients in the AB group compared with nAB, with the pooled OR rate being 0.73 with a 95% CI of 0.37 to 1.44 (P= .357). The 3-year OS rate was 95.63% and 95.54% in the AB and nAB groups, respectively, with no statistical difference (P= .157). There was a significant increase in the rate of LVEF decline of 19.07% in the AB group compared with 13.33% for the nAB group, with an HR of 1.62 and a 95% CI of 1.11 to 2.36 (P = .013).
    UNASSIGNED: The addition of anthracyclines did not improve pCR rates and survival after neoadjuvant and the increased cardiotoxicity of anthracyclines further limited their application. This study showed that it was feasible to use anti-HER2 drugs without anthracyclines in neoadjuvant therapy for HER2-positive breast cancer patients.
