背景& 目的转化生长因子 β(TGF-β)通过促进细胞增殖、转移和免疫抑制,在晚期癌症中发挥致癌作用。在其他肿瘤类型中,PMEPA1(前列腺跨膜蛋白雄激素诱导 1)已被证明可促进 TGF-β 的致癌作用。因此,我们旨在探索PMEPA1在肝细胞癌(HCC)中的作用。方法我们分析了1,097例HCC患者的肿瘤,包括发现组(n = 228)和验证组(n = 361)的基因组和临床病理数据。通过 qPCR(n = 228)、基因表达数据(n = 869)和单细胞水平(n = 54)评估 PMEPA1 水平。结果PMEPA1在18%的HCC样本中过表达(折叠变化>2; n = 201/1,097),这一特征与TGF-β信号激活(p <0.05)和基因体低甲基化缺失(p <0.01)有关。同时显示 TGF-β 信号和高 PMEPA1 水平的 HCC(12% 的病例)与免疫衰竭、晚期 TGF-β 激活、侵袭性和切除后较高的复发率有关,而仅显示 TGF-β 信号的 HCC(8%)或 PMEPA1 过表达的 HCC(9%)则与之相反。单细胞RNA测序分析确定了PMEPA1在HCC和基质细胞中的表达。据预测,表达PMEPA1的肿瘤细胞会与CD4+调节性T细胞、CD4+ CXCL13+和CD8+衰竭性T细胞相互作用。在体内,与单独过表达 MYC 的小鼠相比,过表达 MYC+PMEPA1 会导致 60% 的小鼠发生 HCC 并降低存活率(p = 0.014)。结论在人类 HCC 中,PMEPA1 的上调与 TGF-β 激活、免疫耗竭和侵袭性表型有关。PMEPA1+MYC的过表达导致体内肿瘤发生,首次证明了PMEPA1在HCC中的致癌作用。本研究表明,PMEPA1在18%的肝细胞癌(HCC)患者中高表达,这一特征与预后不良、TGF-β激活和免疫细胞衰竭有关。同样,在小鼠模型中,PMEPA1 的过表达会促进 HCC 的发展,这表明了它的致癌作用。PMEPA1是HCC的致癌驱动因子,它在免疫耗竭和不良临床预后中的作用加深了我们对HCC发病机制的了解,为靶向治疗干预开辟了新途径。

Liver stiffness measurement predicts clinical outcomes in autoimmune hepatitis 肝脏硬度测量可预测自身免疫性肝炎的临床结果
IF 9.5 1区 医学 Q1 GASTROENTEROLOGY & HEPATOLOGY Pub Date : 2024-09-06 DOI: 10.1016/j.jhepr.2024.101213

Background & Aims

Liver stiffness measurement (LSM) has been shown to adequately predict outcomes in patients with liver disease. However, the value of LSM as a predictor of disease progression in autoimmune hepatitis (AIH) remains to be determined. This study aimed to evaluate the role of LSM as a predictor of disease progression and decompensation of cirrhosis in patients with AIH.

Methods

This multicentre cohort study included 439 patients with histologically confirmed AIH and at least one LSM during follow-up. The association between the first LSM performed at least 6 months after treatment initiation (baseline LSM [BLSM]) and cirrhosis development and poor outcomes (decompensation, liver transplantation, and/or liver-related death) was assessed using Cox regression and its discriminating capacity with a receiver-operating characteristic curve.

Results

Most patients were female (n = 301, 70%), with a median age of 52 years. BLSM performed after a median of 2.18 (1.19-4.68) years had a median value of 6 kPa (4.5-8.5). At the time of BLSM, 332 (76%) patients had achieved a biochemical response and 57 (13%) had cirrhosis. During follow-up, eight patients (2%) presented with poor outcomes and 26 (7%) developed cirrhosis. BLSM was higher among patients with poor outcomes (13.5 kPa vs. 6 kPa; p <0.001) and was independently associated with cirrhosis development (hazard ratio 1.300; p <0.001), irrespective of the achievement of biochemical response. A cut-off of 8.5 kPa accurately predicted cirrhosis development and poor outcomes, with AUCs of 0.859 (95% CI 0.789-0.929) and 0.900 (95% CI 0.847-0.954), respectively.

Conclusion

BLSM could play a significant role in predicting AIH outcomes, potentially identifying a subgroup of patients at a high risk of progressing to cirrhosis and experiencing decompensation.

Impact and implications:

The value of liver stiffness measurement as a predictor of outcomes in patients with autoimmune hepatitis (AIH) remains to be determined. In this large multicentre study, liver stiffness measurement was found to be an independent predictive factor of adverse clinical outcomes and cirrhosis development in AIH, irrespective of the achievement of biochemical response. A cut-off of 8.5 kPa accurately predicted cirrhosis development and poor outcomes in AIH.
背景& 目的肝脏僵硬度测量(LSM)已被证明能充分预测肝病患者的预后。然而,肝硬度测量作为自身免疫性肝炎(AIH)疾病进展预测指标的价值仍有待确定。本研究旨在评估 LSM 作为自身免疫性肝炎患者疾病进展和肝硬化失代偿的预测指标的作用。方法这项多中心队列研究纳入了 439 例经组织学确诊的自身免疫性肝炎患者,这些患者在随访期间至少接受过一次 LSM 检查。结果大多数患者为女性(n = 301,70%),中位年龄为 52 岁。在中位 2.18(1.19-4.68)年后进行的 BLSM 的中位值为 6 kPa(4.5-8.5)。在进行 BLSM 时,有 332 名(76%)患者获得了生化应答,57 名(13%)患者出现了肝硬化。在随访期间,8 名患者(2%)出现不良反应,26 名患者(7%)发展为肝硬化。无论是否获得生化应答,预后不良患者的 BLSM 均较高(13.5 kPa vs. 6 kPa; p <0.001),并且与肝硬化的发展独立相关(危险比 1.300; p <0.001)。8.5 kPa 临界值可准确预测肝硬化的发展和不良预后,其 AUC 分别为 0.859 (95% CI 0.789-0.929) 和 0.900 (95% CI 0.847-0.954)。影响和意义:肝脏硬度测量作为自身免疫性肝炎(AIH)患者预后预测指标的价值仍有待确定。在这项大型多中心研究中发现,肝脏僵硬度测量是自身免疫性肝炎患者不良临床结局和肝硬化发展的独立预测因素,与生化反应的实现无关。8.5 kPa的临界值可准确预测AIH患者肝硬化的发生和不良预后。

Predicting liver ablation volumes with real-time MRI thermometry 利用实时磁共振成像测温技术预测肝脏消融体积
IF 9.5 1区 医学 Q1 GASTROENTEROLOGY & HEPATOLOGY Pub Date : 2024-08-31 DOI: 10.1016/j.jhepr.2024.101199

Background & Aims

MRI guidance offers better lesion targeting for microwave ablation of liver lesions with higher soft-tissue contrast, as well as the possibility of real-time thermometry. This study aims to evaluate the correlation of real-time MR thermometry-predicted lesion volume with the ablation zone in postprocedural first-day images.

Methods

This single-center retrospective analysis evaluated prospectively included patients who underwent MRI-guided microwave ablation with real-time thermometry between December 2020 and July 2023. All procedures were performed under general anesthesia on a 1.5 T MRI scanner. Real-time thermometry data were acquired using multi-slice gradient-echo echoplanar imaging sequences, and thermal dose maps (CEM43 of 240 min as a threshold) were created. The volume of tissue exposed to a lethal thermal dose in MR thermometry (thermal dose) was compared with the ablation zone volume in portal phase T1w MRI on the postprocedural first day using the Pearson correlation test, and visual quantitative assessment by radiologists was performed to evaluate the similarity of shapes and volumes.

Results

Out of 30 patients with 33 lesions with thermometry images, six (18.1%) lesions were excluded because of artifacts limiting interpretation of thermal dose volume. Twenty-four patients with 27 lesions (20 male, age 63.1 ± 9.1 years) were evaluated for the volume correlation. The volume of thermal dose-predicted lesions and the postprocedural first-day ablation zones showed a strong correlation (R = 0.89, p <0.001). Similarly, visual similarity of molecular resonance thermometry-predicted shape and the ablation zone shape was graded as perfect in 23 (85.1%) lesions.

Conclusions

Real-time thermal dose-predicted volumes show very good correlation with the ablation zone volumes in images obtained 1 day after the procedure, which could reduce the local recurrence rates with the possibility of re-ablating lesions within the same procedure.

Impact and implications:

Heat-based ablation is an established treatment for liver tumors; however, there is a considerable rate of incomplete treatment because of the lack of real-time visualization of the treated area during treatment. Our results show that MRI-guided ablation enables the visualization of the treatment area in real-time with high accuracy using a special technique of MR thermometry in patients with liver tumors.
背景& 目的MRI引导为肝脏病变的微波消融提供了更好的病灶定位,软组织对比度更高,而且可以进行实时测温。本研究旨在评估实时磁共振温度计预测的病灶体积与术后第一天图像中消融区的相关性。方法这项单中心回顾性分析评估了 2020 年 12 月至 2023 年 7 月期间在磁共振引导下接受实时温度计微波消融术的前瞻性纳入患者。所有手术均在 1.5 T 核磁共振扫描仪上全身麻醉下进行。使用多切片梯度回波回旋成像序列获取实时测温数据,并绘制热剂量图(以240分钟的CEM43为阈值)。使用皮尔逊相关性检验将 MR 测温中暴露于致死热剂量的组织体积(热剂量)与术后第一天门相 T1w MRI 中的消融区体积进行比较,并由放射科医生进行视觉定量评估,以评价形状和体积的相似性。对 24 名患者的 27 个病灶(20 名男性,年龄为 63.1 ± 9.1 岁)进行了体积相关性评估。热剂量预测的病灶体积与手术后第一天的消融区显示出很强的相关性(R = 0.89,p <0.001)。同样,在 23 个(85.1%)病灶中,分子共振测温预测形状与消融区形状的视觉相似度被评为完美。结论实时热剂量预测体积与术后 1 天获得的图像中的消融区体积显示出很好的相关性,这可以降低局部复发率,并有可能在同一次手术中再次消融病灶。影响和意义:热消融是一种治疗肝脏肿瘤的成熟方法,但由于治疗过程中缺乏对治疗区域的实时观察,因此存在相当高的治疗不完全率。我们的研究结果表明,磁共振成像引导下的消融术能利用磁共振测温这一特殊技术实时、高精度地观察肝肿瘤患者的治疗区域。

Hic-5 antisense oligonucleotide inhibits advanced hepatic fibrosis and steatosis in vivo Hic-5反义寡核苷酸抑制体内晚期肝纤维化和脂肪变性
IF 9.5 1区 医学 Q1 GASTROENTEROLOGY & HEPATOLOGY Pub Date : 2024-08-23 DOI: 10.1016/j.jhepr.2024.101195

Background & Aims

Chronic liver diseases, including metabolic dysfunction-associated steatohepatitis (MASH), pose a significant global health burden. Progressive liver fibrosis can lead to severe outcomes; however, there is a lack of effective therapies targeting advanced fibrosis. Hydrogen peroxide-inducible clone-5 (Hic-5), an adaptor protein in focal adhesion, is critical for promoting liver fibrosis in hepatic stellate cells. This study investigated its clinical applicability by examining hepatic Hic-5 expression in human fibrotic tissues, exploring its association with MASH, and assessing the therapeutic potential of antisense oligonucleotides (ASOs) targeting Hic-5 in a MASH mouse model.

Methods

Hepatic Hic-5 expression in human fibrotic tissues underwent pathological image analysis and single-cell RNA sequencing. ASOs targeting Hic-5 were developed and tested using in vitro cell models. An in vivo MASH mouse model was used to evaluate the effects of anti-Hic-5 ASOs on advanced fibrosis and steatosis.

Results

Hepatic Hic-5 expression increased with the progression of fibrosis, particularly in advanced stages. Single-cell RNA sequencing revealed Hic-5 expression primarily in hepatic stellate cells. In MASH-associated fibrosis, Hic-5 expression correlated with the expression of fibrotic genes. In the MASH mouse model, hepatic Hic-5 expression increased with disease progression. Anti-Hic-5 ASOs effectively suppressed Hic-5 expression in vitro and attenuated advanced fibrosis and steatosis in vivo, indicating their therapeutic potential.

Conclusions

Hepatic Hic-5 expression is associated with advanced liver fibrosis and MASH. Anti-Hic-5 ASOs are promising therapeutic interventions for MASH accompanied by advanced fibrosis. These findings provide valuable insights into potential clinical treatments for advanced liver fibrosis.

Impact and implications:

This study investigated the role of Hic-5 in liver fibrosis and steatohepatitis, highlighting its potential as a therapeutic target. We developed an antisense oligonucleotide (ASO) that was particularly transportable to the liver, and targeted Hic-5. Anti-Hic-5 ASO exhibited therapeutic efficacy for liver fibrosis and steatosis in vivo, indicating its therapeutic potential for liver fibrosis and steatosis. ASOs have already achieved dramatic therapeutic effects as approved nucleic acid drugs. Thus, anti-Hic-5 ASO is expected to lead the direct generation of seed compounds for the clinical development of drugs for liver fibrosis and steatosis.
背景与ampamp; 目的慢性肝病,包括代谢功能障碍相关性脂肪性肝炎(MASH),给全球健康造成了重大负担。进行性肝纤维化可导致严重后果;然而,目前缺乏针对晚期肝纤维化的有效疗法。过氧化氢诱导的克隆-5(Hic-5)是一种局灶粘附的适配蛋白,对促进肝星状细胞的肝纤维化至关重要。本研究通过检测肝纤维化组织中肝脏Hic-5的表达,探讨其与MASH的关联,并在MASH小鼠模型中评估靶向Hic-5的反义寡核苷酸(ASOs)的治疗潜力,从而研究其临床适用性。方法对肝纤维化组织中肝脏Hic-5的表达进行病理图像分析和单细胞RNA测序。利用体外细胞模型开发并测试了靶向 Hic-5 的 ASO。结果肝脏Hic-5的表达随着纤维化的进展而增加,尤其是在晚期。单细胞 RNA 测序显示 Hic-5 主要在肝星状细胞中表达。在MASH相关纤维化中,Hic-5的表达与纤维化基因的表达相关。在MASH小鼠模型中,肝脏Hic-5的表达随着疾病的进展而增加。抗 Hic-5 ASOs 在体外能有效抑制 Hic-5 的表达,在体内能减轻晚期肝纤维化和脂肪变性,显示了其治疗潜力。抗 Hic-5 ASOs 对伴有晚期肝纤维化的 MASH 有很好的治疗效果。影响和意义:本研究调查了Hic-5在肝纤维化和脂肪性肝炎中的作用,强调了其作为治疗靶点的潜力。我们开发了一种反义寡核苷酸(ASO),这种寡核苷酸特别容易转运到肝脏,并以Hic-5为靶点。抗Hic-5 ASO对体内肝纤维化和脂肪变性具有疗效,这表明它对肝纤维化和脂肪变性具有治疗潜力。作为已获批准的核酸药物,ASO 已经取得了显著的治疗效果。因此,抗Hic-5 ASO有望成为直接用于肝纤维化和脂肪变性药物临床开发的种子化合物。

Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a spectrum of disease states ranging from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), which can eventually lead to the development of cirrhosis and hepatocellular carcinoma. Macrophages have long been implicated in driving the progression from steatosis to end-stage disease, yet we still know relatively little about the precise involvement of these cells in MASLD progression and/or regression. Rather, there are a considerable number of conflicting reports regarding the precise roles of these cells. This confusion stems from the fact that, until recently, macrophages in the liver were considered a homogenous population. However, thanks to recent technological advances including multi-parameter flow cytometry, single-cell RNA sequencing and spatial proteogenomics, we now know that this is not the case. Rather hepatic macrophages, even in the healthy liver, are heterogenous, existing in multiple subsets with distinct transcriptional profiles and hence likely functions. This heterogeneity is even more prominent in MASLD, where the macrophage pool consists of multiple different subsets of resident and recruited cells. To probe the unique functions of these cells and determine if targeting macrophages may be a viable therapeutic strategy in MASLD, we first need to unravel this complexity and decipher which populations and/or activation states are present and what functions each of these may play in driving MASLD progression. In this review, we summarise recent advances in the field, highlighting what is currently known about the hepatic macrophage landscape in MASLD and the questions that remain to be tackled.
代谢功能障碍相关性脂肪性肝病(MASLD)代表了从单纯性脂肪变性到代谢功能障碍相关性脂肪性肝炎(MASH)的一系列疾病状态,最终可导致肝硬化和肝细胞癌的发生。长期以来,巨噬细胞一直被认为是脂肪变性进展到终末期疾病的驱动因素,但我们对这些细胞在 MASLD 进展和/或消退过程中的确切参与情况仍然知之甚少。相反,关于这些细胞的确切作用,有相当多的报道相互矛盾。造成这种混乱的原因是,直到最近,肝脏中的巨噬细胞一直被认为是一个同质的群体。然而,随着多参数流式细胞仪、单细胞 RNA 测序和空间蛋白质组学等最新技术的发展,我们现在知道事实并非如此。相反,即使在健康的肝脏中,肝巨噬细胞也是异质的,存在多个亚群,具有不同的转录特征,因此可能具有不同的功能。这种异质性在 MASLD 中更为突出,巨噬细胞池由多个不同的常驻和招募细胞亚群组成。要探究这些细胞的独特功能并确定以巨噬细胞为靶点是否是一种可行的MASLD治疗策略,我们首先需要揭开这种复杂性的面纱,破解存在哪些种群和/或活化状态,以及这些种群和/或活化状态在推动MASLD进展中可能发挥的功能。在这篇综述中,我们总结了该领域的最新进展,强调了目前对MASLD中肝巨噬细胞状况的了解以及仍有待解决的问题。

Patient and physician expectations regarding disease and treatment of advanced HCC: The prospective PERCEPTION1 study 患者和医生对晚期 HCC 疾病和治疗的期望:前瞻性 PERCEPTION1 研究
IF 9.5 1区 医学 Q1 GASTROENTEROLOGY & HEPATOLOGY Pub Date : 2024-08-22 DOI: 10.1016/j.jhepr.2024.101192

Background & Aims

We aimed to explore patient expectations regarding their treatments and prognosis in comparison to physicians' assessments in patients with advanced hepatocellular carcinoma (HCC) receiving systemic treatments.

Methods

We prospectively enrolled 205 patients in France and Belgium with Barcelona Clinic Liver Cancer (BCLC) stage B/C HCC receiving systemic treatment (NCT04823754). Patients completed a 28-question survey and the hospital anxiety and depression scale (HADS), while physicians filled a 17-question survey after the initial consultation. Univariate and multivariate models were used to assess factors associated with concordant patient-physician responses, HADS, as well as predicted (by physicians) and observed overall survival.

Results

Patients had a median age of 68 years with 75% having BCLC C HCC; 86.3% received atezolizumab/bevacizumab. 60% of patients did not discuss life expectancy with the physician. 63% of the patients believed they had a life expectancy >5 years. Among shared questions between patients and physicians, 36.4% concordance was observed; major differences centered on life expectancy with patients more optimistic than physicians. A lower patient-physician concordance was seen with shorter-consultations (p = 0.003), female physicians (p = 0.02), BCLC C (p = 0.03) and >100 HCC patients/year per physician (p = 0.008). Compared to France, patients from Belgium were more likely to be satisfied with the consultation (p <0.001) but were less optimistic about life expectancy. Using HADS, 52% of the patients had anxiety/depression that was correlated with alpha-fetoprotein level (p = 0.03). The predicted median overall survival by physicians was 18 months vs. 13 months for the observed overall survival (weak correlation, ρ = 0.31).

Conclusion

Expectations regarding systemic treatments for advanced HCC differ significantly between patients and physicians, showing notable variations across countries.

Impact and implications:

This multicentric prospective study, conducted in France and Belgium, focuses on patients with advanced hepatocellular carcinoma undergoing systemic treatments. The findings of our study underscore the disparities in expectations regarding systemic treatments for advanced hepatocellular carcinoma between patients and physicians, revealing also significant variations between France and Belgium. These results suggest the need for targeted interventions aimed at enhancing patients' comprehension of their disease and fostering better communication between patients and physicians.

背景& 目的在肝硬化患者中,急性失代偿(AD)与线粒体功能障碍导致的高炎症状态相关,而线粒体功能障碍是导致急性-慢性肝衰竭(ACLF)进展的重要因素。表明线粒体功能障碍的酰基肉碱循环水平升高是 ACLF 患者死亡率的预测因素。我们的假设认为,酰基肉碱不仅是生物标志物,还能对循环免疫细胞产生有害影响。方法测量了 20 名 AD 肝硬化患者和 10 名健康人的血浆酰基肉碱水平。通过使用 JC-1 染料和 Agilent Seahorse XF 技术测定线粒体膜电位(Δψm)和线粒体呼吸,研究了所选的中链和长链酰基肉碱对健康供体外周白细胞线粒体功能的影响。结果与健康人相比,AD 型肝硬化患者血浆中几种酰基肉碱的水平显著升高,同时炎症介质(细胞因子和趋化因子)的水平也升高。值得注意的是,长链酰基肉碱棕榈酰肉碱(C16:0-肉碱,高 1.51 倍,p = 0.0059)会损害Δψm,降低外周单核白细胞的剩余呼吸能力。此外,C16:0-肉碱诱导线粒体氧化应激,抑制抗氧化基因 HMOX1 的表达,增加 CXCL8 的表达和 IL-8 的释放。阻断酰基肉碱进入线粒体的 Etomoxir 逆转了对 HMOX1 的抑制。同样,脂肪酸β-氧化抑制剂曲美他嗪也能阻止C16:0-肉碱诱导的CXCL8表达。重要的是,在白蛋白存在的情况下,C16:0-肉碱引起的氧化应激和Δψm损伤的程度较轻,而白蛋白是治疗 AD 肝硬化的标准疗法。结论我们的研究结果表明,长链酰基肉碱会诱导免疫细胞的线粒体损伤,从而导致与肝硬化相关的免疫功能紊乱。影响和意义肝硬化急性失代偿期和急性慢性肝衰竭(ACLF)患者表现出全身高炎症状态和白细胞线粒体功能障碍。我们发现,长链棕榈酰肉碱除了在这些患者的血液循环中增加外,还能引起细胞因子分泌,同时导致健康供体的白细胞线粒体功能障碍。我们的研究特别表明,抑制棕榈酰肉碱的代谢可以逆转这些有害影响。我们的研究结果凸显了免疫代谢作为肝硬化急性失代偿期和 ACLF 患者治疗目标的重要性。

Heterogeneity in adverse events related to atezolizumab-bevacizumab for hepatocellular carcinoma reported in real-world studies 真实世界研究中报告的与阿特珠单抗-贝伐单抗治疗肝细胞癌相关的不良事件存在异质性
IF 9.5 1区 医学 Q1 GASTROENTEROLOGY & HEPATOLOGY Pub Date : 2024-08-22 DOI: 10.1016/j.jhepr.2024.101190

Background & Aims

Safety data for patients with hepatocellular carcinoma (HCC) treated with atezolizumab-bevacizumab in the real-world setting remain uncertain. Thus, the aim of this study was to evaluate the incidence of adverse events (AEs) in patients with HCC treated with atezolizumab-bevacizumab in the literature.

Methods

In this systematic review and meta-analysis, we searched PubMed for original studies reporting percentages of AEs in patients with HCC receiving atezolizumab-bevacizumab between 2020 to 2023, using the search terms “Atezolizumab/Bevacizumab”, “HCC” and “Adverse events”. We summarized the incidence of AEs and performed a meta-analysis in order to evaluate the incidence of AEs reported in the literature.

Results

A total of 30 studies (3,867 patients) were included. The analysis revealed heterogeneity in AE reporting, with arterial hypertension, proteinuria, and fatigue being the most frequently reported AEs whereas incidence of bleeding was reported in 66.7% of the studies and rare immune-related AEs were reported in 26.7% of the studies. The meta-analysis revealed pooled incidence rates of 79% for any grade AEs: 56% for grade 1/2 and 30% for grade ≥3. While the pooled rates of hypertension, anorexia, bleeding, pruritus, rash, and thyroid dysfunction were similar to those reported in the IMbrave150 trial, higher rates were observed in the literature for proteinuria, fatigue, ALT and AST elevations and gastrointestinal perforation. For grade ≥3 AEs, the percentages were consistent with the IMbrave150 trial, except for lower incidences of arterial hypertension and thrombosis in the literature. The exposure-adjusted incidence rates for proteinuria (55.7%), hypertension (45.3%) and fatigue (33.6%) were high. Heterogeneity was observed in the analysis of AEs across articles within the same cohorts of patients.

Conclusion

We observed a significant variability in AE reporting for atezolizumab-bevacizumab treatment in HCC in the literature, underscoring the need for standardized reporting practices.

Impact and implications

Considering the demonstrated safety of atezolizumab-bevacizumab in randomized-controlled trials, this meta-analysis offers valuable insights into reported occurrences of adverse events. Our study highlights significant heterogeneity among studies, underscoring the need to improve adverse event recording. Understanding the incidence and severity of treatment-related adverse events beyond clinical trials is essential for prompt intervention and may help in preventing treatment discontinuation and complications, potentially leading to better outcomes without significantly compromising quality of life due to adverse events.
背景& 目的在现实世界中,阿特珠单抗-贝伐单抗治疗肝细胞癌(HCC)患者的安全性数据仍不确定。因此,本研究旨在评估文献中使用atezolizumab-bevacizumab治疗的HCC患者的不良事件(AEs)发生率。方法在本系统综述和荟萃分析中,我们使用 "Atezolizumab/Bevacizumab"、"HCC "和 "不良事件 "等检索词,在PubMed上检索了报告2020年至2023年间接受atezolizumab-bevacizumab治疗的HCC患者AEs百分比的原创研究。我们总结了AEs的发生率,并进行了荟萃分析,以评估文献中报道的AEs发生率。分析显示,AE 报告存在异质性,动脉高血压、蛋白尿和疲劳是最常报告的 AE,而 66.7% 的研究报告了出血,26.7% 的研究报告了罕见的免疫相关 AE。荟萃分析显示,任何等级的AEs的汇总发生率为79%:56%为1/2级,30%为≥3级。虽然高血压、厌食、出血、瘙痒、皮疹和甲状腺功能障碍的集合发生率与IMbrave150试验报告的相似,但在文献中观察到蛋白尿、疲劳、ALT和AST升高以及胃肠道穿孔的发生率较高。对于≥3级的AEs,除了文献中动脉高血压和血栓形成的发生率较低外,其他百分比与IMbrave150试验一致。经暴露调整后,蛋白尿(55.7%)、高血压(45.3%)和疲劳(33.6%)的发生率较高。结论我们在文献中观察到atezolizumab-bevacizumab治疗HCC的AE报告存在显著差异,强调了标准化报告实践的必要性。影响和意义考虑到atezolizumab-bevacizumab在随机对照试验中被证实具有安全性,本荟萃分析为了解不良事件的报告情况提供了宝贵的见解。我们的研究强调了不同研究之间的显著异质性,突出了改进不良事件记录的必要性。在临床试验之外,了解治疗相关不良事件的发生率和严重程度对于及时干预至关重要,并可能有助于防止治疗中断和并发症的发生,从而在不因不良事件而严重影响生活质量的情况下获得更好的治疗效果。
