    肝细胞癌(HCC)的局部消融,一种直接靶向和破坏肿瘤细胞的非手术选择,自20世纪90年代以来取得了显著进展。不同能量来源的疗法,例如射频消融,微波消融,冷冻消融,采用不同的机制诱导肿瘤坏死。精度,安全,随着引导技术和设备改进的进步,这些疗法的有效性也有所提高。因此,局部消融已成为早期HCC的一线治疗方法.缺乏关于患者选择的有组织的证据和专家意见,术前准备,程序方法,快速的治疗后评估,随访导致临床医生遵循不同的做法。因此,韩国肝癌协会研究委员会的一组放射学和肝病学专家与韩国影像引导肿瘤消融学会合作,制定了一项基于专家共识的局部消融实用建议,为进行局部消融以及患者治疗前后的管理提供有用的信息和指导.
    Local ablation for hepatocellular carcinoma (HCC), a non-surgical option that directly targets and destroys tumor cells, has advanced significantly since the 1990s. Therapies with different energy sources, such as radiofrequency ablation, microwave ablation, and cryoablation, employ different mechanisms to induce tumor necrosis. The precision, safety, and effectiveness of these therapies have increased with advances in guiding technologies and device improvements. Consequently, local ablation has become the first-line treatment for early-stage HCC. The lack of organized evidence and expert opinions regarding patient selection, pre-procedure preparation, procedural methods, swift post-treatment evaluation, and follow-up has resulted in clinicians following varied practices. Therefore, an expert consensus-based practical recommendation for local ablation was developed by a group of experts in radiology and hepatology from the Research Committee of the Korean Liver Cancer Association in collaboration with the Korean Society of Image-guided Tumor Ablation to provide useful information and guidance for performing local ablation and for the pre- and post-treatment management of patients.

    肝细胞癌(HCC)提出了重大的临床挑战,需要整合免疫治疗方法。Palbociclib,选择性CDK4/6抑制剂,已在临床前HCC模型中证明了有希望的疗效,并且正在临床试验中被评估为一种新颖的治疗选择。此外,CDK4/6抑制诱导细胞衰老,可能影响肿瘤微环境和癌细胞的免疫原性。在这项研究中,我们使用不同的HCC转录组数据集进行了全面的生物信息学分析,包括来自公共数据库的批量和单细胞RNA测序数据。我们还利用人和小鼠HCC细胞来研究功能方面。从小鼠血液中分离的原代T细胞用于评估针对HCC细胞的T细胞免疫。结果显示,CD8+T细胞浸润与CDK4/6表达抑制的HCC患者预后改善相关。此外,CDK4/6表达与肝脏肿瘤微环境中免疫景观和免疫检查点表达的改变有关。此外,我们发现Palbociclib和阿霉素治疗可诱导肝癌细胞衰老和衰老相关的分泌表型.值得注意的是,Palbociclib预处理增强了T细胞介导的对HCC细胞的细胞毒性,尽管PD-L1上调,超过了阿霉素预处理的效果。总之,我们的研究阐明了CDK4/6抑制增强T细胞相关癌症消除的新机制,并提出了增强T细胞免疫治疗HCC的潜在治疗策略.
    Hepatocellular carcinoma (HCC) poses a significant clinical challenge, necessitating the integration of immunotherapeutic approaches. Palbociclib, a selective CDK4/6 inhibitor, has demonstrated promising efficacy in preclinical HCC models and is being evaluated as a novel therapeutic option in clinical trials. Additionally, CDK4/6 inhibition induces cellular senescence, potentially influencing the tumor microenvironment and immunogenicity of cancer cells. In this study, we conducted comprehensive bioinformatic analyses using diverse HCC transcriptome datasets, including bulk and single-cell RNA-sequencing data from public databases. We also utilized human and mouse HCC cells to investigate functional aspects. Primary T cells isolated from mouse blood were employed to assess T cell immunity against HCC cells. Results revealed that CD8+ T-cell infiltration correlates with improved outcomes in HCC patients with suppressed CDK4/6 expression. Moreover, CDK4/6 expression was associated with alterations in the immune landscape and immune checkpoint expression within the liver tumor microenvironment. Furthermore, we found that treatment with Palbociclib and Doxorubicin induces cellular senescence and a senescence-associated secretory phenotype in HCC cells. Notably, pretreatment with Palbociclib augmented T cell-mediated cytotoxicity against HCC cells, despite upregulation of PD-L1, surpassing the effects of Doxorubicin pretreatment. In conclusion, our study elucidates a novel mechanism by which CDK4/6 inhibition enhances T-cell-associated cancer elimination and proposes a potential therapeutic strategy to enhance T-cell immunotherapy on HCC.

    肝细胞癌(HCC)是一种生物学异质性肿瘤,其特征是具有不同程度的侵袭性。目前HCC的治疗策略主要由整体肿瘤负荷决定。由于其异质性,并不能解决HCC患者的不同预后。因此,使用影像学数据预测HCC对于优化患者管理至关重要.虽然一些放射学特征已被证明是指示HCC的生物学行为,HCC预后的传统放射学方法是基于视觉评估的预后结果,并且受到主观性和观察者间可变性的限制。因此,人工智能已成为一种有前途的基于图像的HCC预测方法。与传统的放射影像分析不同,基于影像组学或深度学习的人工智能利用大量图像衍生的定量特征,可能提供一个目标,detailed,并对肿瘤表型进行综合分析。人工智能,特别是影像组学在各种应用中显示出潜力,包括微血管侵犯的预测,局部治疗后复发风险,和对全身治疗的反应。这篇综述强调了人工智能在HCC预测中的潜在价值,以及其局限性和未来前景。
    Hepatocellular carcinoma (HCC) is a biologically heterogeneous tumor characterized by varying degrees of aggressiveness. The current treatment strategy for HCC is predominantly determined by the overall tumor burden, and does not address the diverse prognoses of patients with HCC owing to its heterogeneity. Therefore, the prognostication of HCC using imaging data is crucial for optimizing patient management. Although some radiologic features have been demonstrated to be indicative of the biologic behavior of HCC, traditional radiologic methods for HCC prognostication are based on visually-assessed prognostic findings, and are limited by subjectivity and inter-observer variability. Consequently, artificial intelligence has emerged as a promising method for image-based prognostication of HCC. Unlike traditional radiologic image analysis, artificial intelligence based on radiomics or deep learning utilizes numerous image-derived quantitative features, potentially offering an objective, detailed, and comprehensive analysis of the tumor phenotypes. Artificial intelligence, particularly radiomics has displayed potential in a variety of applications, including the prediction of microvascular invasion, recurrence risk after locoregional treatment, and response to systemic therapy. This review highlights the potential value of artificial intelligence in the prognostication of HCC as well as its limitations and future prospects.

    鼻咽癌(NPC)患者远处转移是预期寿命降低的原因之一,最常见的转移扩散到骨,肝脏,还有肺.肝癌是最常见的肝脏恶性肿瘤,是全球癌症死亡的最高原因之一,这可能是NPC转移的结果。此病例报告的目的是介绍一名因NPC转移而怀孕的肝癌患者。一名34岁的怀孕女性在妊娠24-25周时表现出胃灼热和难以忍受的疼痛放射到背部的主要抱怨。既往病史报告患者肝脏肿大。患者为G4P2A1,具有单个存活的宫内胎儿和活跃的胎儿运动。患者有NPC病史,并在入院前一个月接受了完整的放化疗。体格检查显示右腹上腹象限双侧啰音和可触及的弥漫性多发结节。实验室检查显示贫血,血小板减少症,阴性乙型肝炎表面抗原(HBsAg),和肝脏标志物升高。腹部超声检查结果显示肝脏有多个弥漫性结节。根据临床和影像学发现,该患者被诊断为转移性肝癌。住院期间,患者反复出现胸腔积液并怀疑转移。几天后,胎动停止,超声检查提示胎心率为阴性.在经历了数小时的呼吸窘迫后,病人第二天就过期了。该病例强调,由于化疗和放疗的潜在不良反应,应谨慎决定开始这些疗法,以避免对母亲和胎儿造成不良影响.
    Distant metastasis in nasopharyngeal carcinoma (NPC) patients is one of the reasons for the decreased life expectancy with the most common metastasis spreads are to the bone, liver, and lung. Hepatoma is the most frequent liver malignancy and is one of the highest causes of cancer death worldwide and this can be as a result of NPC metastasis. The aim of this case report was to present a patient with hepatoma in pregnancy as a result of NPC metastasis. A 34-year-old pregnant female at 24-25 weeks of gestation presented with a chief complaint of heartburn and unbearable pain radiating to the back. Previous medical history reported that the patient had a liver enlargement. The patient was G4P2A1 with a single living intrauterine fetus and active fetal movements. The patient has a history of NPC and received a completed chemoradiation one month prior to hospital admission. Physical examination showed bilateral rales and palpable diffuse multiple nodule masses in the upper right abdominal quadrant. Laboratory examination revealed anemia, thrombocytopenia, negative hepatitis B surface antigen (HBsAg), and elevated liver markers. Abdominal ultrasonography results showed multiple diffuse nodules in the liver. The patient was diagnosed with a metastatic hepatoma based on the clinical and imaging findings. During hospitalization, the patient repeatedly experienced pleural effusion with suspicion metastases. A few days later, the fetal movements stopped and the ultrasonography indicated negative fetal heart rate. After experiencing respiratory distress for hours, the patient expired the day after. This case highlights that due to the potential adverse effects of chemotherapy and radiotherapy, the initiation of these therapies should be carefully decided to avoid adverse effects to mother and fetus.

    肝细胞癌(HCC),原发性肝癌最常见的类型,代表着全球日益增长的健康挑战。肝癌的发病率正在上升,which,反过来,导致相关死亡人数相应增加。到2030年,HCC将成为美国癌症相关死亡的第三大原因。HCC通常在慢性肝病的背景下发展。建议HCC风险增加的个体每6个月进行超声监测以及血清α-甲胎蛋白检测。计算机断层扫描(CT)和磁共振成像(MRI)被认为是基于特定患者因素的替代方案。建议对HCC的可疑病变进行诊断测试,当发现不确定时,包括对比增强的多相CT或MRI和肝活检。巴塞罗那临床肝癌预后和治疗策略是肝癌患者最常用的评估(图。2).治疗包括切除,肝移植,和消融。局部疗法,如经动脉化疗栓塞和放射栓塞,可用于中期肝癌患者。对于晚期肝癌患者,经常使用系统治疗。这篇综述旨在从肝病学家的角度对肝癌进行概述,包括流行病学,筛选,监视,诊断,和管理。
    Hepatocellular carcinoma (HCC), the most common type of primary liver cancer, represents a growing health challenge worldwide. The incidence of HCC is rising, which, in turn, has led to a corresponding increase in the associated number of deaths. HCC will become the third leading cause of cancer-related deaths in the United States by 2030. HCC usually develops in the setting of chronic liver disease. Individuals at increased risk of HCC are recommended to undergo surveillance with ultrasound every 6 months along with serum α-fetoprotein testing. Computed tomography (CT) and magnetic resonance imaging (MRI) are considered alternatives based on specific patient factors. Lesions suspicious for HCC are recommended to undergo a diagnostic testing, which includes contrast-enhanced multiphase CT or MRI and liver biopsy when findings are indeterminate. The Barcelona Clinic Liver Cancer prognosis and treatment strategy is the most used assessment for patients with HCC ( Fig. 2 ). Curative therapies include resection, liver transplantation, and ablation. Locoregional therapies, such as transarterial chemoembolization and radioembolization, can be used for patients with intermediate-stage HCC. For patients with advanced-stage HCC, systemic therapy is often used. This review aims to provide an overview of HCC from a hepatologist\'s perspective, including epidemiology, screening, surveillance, diagnosis, and management.

    hanganumharmalaL.(P.harmala),也被称为Espand,哈梅尔,或者叙利亚的Rue,和贯叶连翘(H.perforatum),通常被称为圣约翰草,是两种广泛种植的工业作物,在全球范围内用于抗肝癌相关产品。然而,它们的主要功能物质仍然不清楚,从而阻碍了世界各地相关产品的疗效评价和质量控制。在这项工作中,通过建立主成分分析(PCA)-HPLC次级代谢产物作图模型,阐明了P.harmala和H.perforatum的抗肝癌生物标志物.通过HPLC对植物提取物的化学指纹图谱进行分析,然后使用PCA绘制以产生次级代谢产物模型。这些模型将化学信息与植物提取物的抗肝癌活性相关联,从而表明P.harmala和H.perforatum抗肝癌细胞的功能抑制剂。所鉴定的化合物的活性通过细胞毒性和凋亡测定来验证。确定了P.harmala和H.perforatus对人肝癌的主要抑制剂是harmine和槲皮素,分别。harmine对HepG2细胞的IC50值和诱导凋亡率分别为20.7±2.8μM和46.7±3.5%。分别。槲皮素对HepG2细胞的IC50值和诱导凋亡率分别为49.5±6.6μM和38.7±2.6%。分别。总之,结果大大扩展了对P.harmala和H.perforatum的生化基础的理解,因此,显然支持他们目前在世界各地的应用。此外,harmine和槲皮素可作为生物标志物,用于评估工业作物相关产品在治疗和改善健康应用中的功效和质量。
    Peganum harmala L. (P. harmala), also known as Espand, Harmel, or Syrian rue, and Hypericum perforatum L. (H. perforatum), commonly known as St. John\'s wort, are two of the widely cultivated industrial crops and used worldwide in antihepatoma-related products. However, their main functional substances are still not clear, thus impeding the efficacy evaluations and quality controls of relative products around the world. In this work, the anti-hepatoma biomarkers of P. harmala and H. perforatum were clarified through the development of principal components analysis (PCA)-HPLC secondary metabolite mapping models. The chemical fingerprints of plant extracts were profiled by HPLC and then mapped to produce the secondary metabolite models using PCA. The models correlated the chemical information with the anti-hepatoma activities of plant extracts, thus indicating the functional inhibitors of P. harmala and H. perforatum against hepatoma cells. The activities of the identified compounds were validated by cytotoxic and apoptotic assays. The major inhibitors of P. harmala and H. perforatum against human hepatoma were determined to be harmine and quercetin, respectively. The IC50 values and the induced apoptotic rate of harmine on HepG2 cells were 20.7 ± 2.8 μM and 46.7 ± 3.5 %, respectively. The IC50 values and the induced apoptotic rate of quercetin on HepG2 cells were 49.5 ± 6.6 μM and 38.7 ± 2.6 %, respectively. In conclusion, the results significantly expanded the understanding of the biochemical foundations of P. harmala and H. perforatum, thus evidently supporting their current applications around the world. Moreover, harmine and quercetin could be used as biomarkers to evaluate the efficacy and quality of related products of industrial crops in therapeutic and health-improving applications.

    阳性计算机断层扫描(CT)对比剂在诊断肿瘤中具有重要应用。然而,肝癌和正常肝组织之间的敏感区分仍然具有挑战性。这一挑战主要是因为正常肝脏和肝癌组织都捕获了纳米剂,导致类似的阳性CT对比。这里,提出了一种融合阳性和阴性CT对比剂纳米剂的策略来检测肝癌。纳米剂Hf-MOF@AB@PVP最初在肝脏中产生120.3HU的阳性CT对比信号。随后,它能特异性响应肝癌的酸性微环境产生H2,进一步实现-96.0HU的负对比度。更重要的是,阴性和阳性信号区的相对位置有助于确定肝癌和正常肝组织的位置。正常肝脏和肿瘤组织之间216.3HU和相对方向的明显对比差异对于利用CT成像灵敏区分肝癌和正常肝脏组织具有重要意义。
    Positive computed tomography (CT) contrast nanoagent has significant applications in diagnosing tumors. However, the sensitive differentiation between hepatoma and normal liver tissue remains challenging. This challenge arises primarily because both normal liver and hepatoma tissues capture the nanoagent, resulting in similar positive CT contrasts. Here, a strategy for fusing positive and negative CT contrast nanoagent is proposed to detect hepatoma. A nanoagent Hf-MOF@AB@PVP initially generates a positive CT contrast signal of 120.3 HU in the liver. Subsequently, it can specifically respond to the acidic microenvironment of hepatoma to generate H2 , further achieving a negative contrast of -96.0 HU. More importantly, the relative position between the negative and positive signals area is helpful to determine the location of hepatoma and normal liver tissues. The distinct contrast difference of 216.3 HU and relative orientation between normal liver and tumor tissues are meaningful to sensitively distinguish hepatoma from normal liver tissue utilizing CT imaging.
