    肝癌是一个全球性的健康挑战,造成重大的社会经济负担。肝细胞癌(HCC)是原发性肝癌的主要类型,在分子和细胞特征方面是高度异质的。早期或小肿瘤通常用手术或消融治疗。目前,化疗和免疫疗法是不可切除肿瘤或晚期HCC的最佳治疗方法。然而,药物反应和获得性耐药是不可预测的与现有的系统指南有关的突变模式和分子生物标志物,导致许多非典型分子谱患者的治疗结局不佳。凭借先进的技术平台,有价值的信息,如肿瘤遗传改变,表观遗传数据,和肿瘤微环境可以从液体活检获得。说明了肝癌的肿瘤间和肿瘤内异质性,这些数据为治疗方案的决策过程提供了坚实的证据.本文回顾了目前对HCC检测方法的理解,旨在更新使用液体活检进行HCC监测的发展。最近在分子基础上的重要发现,表观遗传概况,循环肿瘤细胞,循环DNA,和组学研究详细阐述了肝癌的诊断。此外,讨论了与治疗选择相关的生物标志物。还强调了一些最近关于靶向治疗的值得注意的临床试验。提供见解,将知识转化为潜在的生物标志物,用于检测和诊断。预后,治疗反应,以及在临床实践中的耐药指标。
    Liver cancer is a global health challenge, causing a significant social-economic burden. Hepatocellular carcinoma (HCC) is the predominant type of primary liver cancer, which is highly heterogeneous in terms of molecular and cellular signatures. Early-stage or small tumors are typically treated with surgery or ablation. Currently, chemotherapies and immunotherapies are the best treatments for unresectable tumors or advanced HCC. However, drug response and acquired resistance are not predictable with the existing systematic guidelines regarding mutation patterns and molecular biomarkers, resulting in sub-optimal treatment outcomes for many patients with atypical molecular profiles. With advanced technological platforms, valuable information such as tumor genetic alterations, epigenetic data, and tumor microenvironments can be obtained from liquid biopsy. The inter- and intra-tumoral heterogeneity of HCC are illustrated, and these collective data provide solid evidence in the decision-making process of treatment regimens. This article reviews the current understanding of HCC detection methods and aims to update the development of HCC surveillance using liquid biopsy. Recent critical findings on the molecular basis, epigenetic profiles, circulating tumor cells, circulating DNAs, and omics studies are elaborated for HCC diagnosis. Besides, biomarkers related to the choice of therapeutic options are discussed. Some notable recent clinical trials working on targeted therapies are also highlighted. Insights are provided to translate the knowledge into potential biomarkers for detection and diagnosis, prognosis, treatment response, and drug resistance indicators in clinical practice.

    本研究旨在探讨TACE联合Lenvatinib和PD-1阻滞治疗肝癌合并门静脉癌栓(PVTT)的疗效和安全性的可行性。
    在临床实践中接受TACE联合Lenvatinib和PD-1阻断作为一线治疗的HCC和PVTT患者。所有受试者定期随访以获得预后结果。收集并记录在联合治疗期间观察到的安全性概况。预后和基线特征的探索性分析采用Log秩检验,多因素分析采用Cox回归分析。
    本研究纳入了67例接受TACE联合Lenvatinib和PD-1阻断的PVTTHCC患者。治疗期间最佳治疗反应提示4例患者达到完全缓解,30例患者出现部分反应,25例患者病情稳定,5例患者有疾病进展,3例患者无疾病进展。该方案的客观缓解率为50.7%[95%置信区间(CI):38.2-63.2%],疾病控制率为88.1%(95%CI:77.8-94.7%)。67例接受TACE联合Lenvatinib和PD-1阻断的PVTTHCC患者的中位无进展生存期为9.3个月(95%CI:5.85-12.75),中位总生存期为24.4个月(95%CI:19.11~29.69).安全性概况强调,65例患者在治疗期间出现不良反应,无论级别如何(97.0%)。其中34例患者被视为≥3级不良反应(50.7%)。最常见的不良反应是高血压,疲劳,肝功能异常,恶心,呕吐,和腹泻。不良反应总体可接受且可控。
    TACE联合Lenvatinib和PD-1阻断作为PVTTHCC的一线治疗显示出潜在的可行性和令人鼓舞的临床结果,为HCC患者提供长期生存益处。这一结论应在前瞻性大规模临床试验中得到证实。
    UNASSIGNED: This study aimed to investigate the feasibility of the efficacy and safety of TACE combined with Lenvatinib and PD-1 blockade in HCC with portal vein tumor thrombus (PVTT).
    UNASSIGNED: Patients with HCC and PVTT who underwent TACE combined with Lenvatinib and PD-1 blockade as first-line therapy in clinical practice were retrospectively included. All subjects were followed-up regularly to obtain prognostic outcomes. The safety profile observed during the combination therapy was collected and documented. The Log rank test was used for exploratory analysis of prognosis and baseline characteristics and Cox regression analysis was used for multivariate analysis.
    UNASSIGNED: A total of 67 HCC patients with PVTT who received TACE combined with Lenvatinib and PD-1 blockade were included in this study. The best therapeutic response during treatment suggested that 4 patients achieved complete response, 30 patients showed partial response, 25 patients were stable disease, 5 patients had disease progression and 3 patients were not available. Objective response rate of this regimen was 50.7% [95% confidence interval (CI): 38.2-63.2%] and disease control rate was 88.1% (95% CI: 77.8-94.7%). The median progression-free survival of 67 HCC patients with PVTT who received TACE combined with Lenvatinib and PD-1 blockades was 9.3 months (95% CI: 5.85-12.75), and the median overall survival was 24.4 months (95% CI: 19.11-29.69). The safety profile highlighted that 65 patients experienced adverse reactions regardless of grade during treatment (97.0%), among whom 34 patients were deemed as grade ≥3 adverse reactions (50.7%). The most common adverse reactions were hypertension, fatigue, abnormal liver function, nausea, vomiting, and diarrhea. Overall adverse reactions were acceptable and controllable.
    UNASSIGNED: TACE combined with Lenvatinib and PD-1 blockades as first-line therapy for HCC with PVTT demonstrated potential feasibility and encouraging clinical outcomes, providing long-term survival benefits for HCC patients. This conclusion should be confirmed in prospective large-scale clinical trials.

    肝切除术可以为I/II型门静脉肿瘤血栓形成(PVTT)的肝细胞癌(HCC)提供更好的生存益处。然而,术后复发率仍然很高。我们讨论了新辅助治疗是否可以减少这些患者的HCC复发。
    回顾性纳入了130例Ⅰ-Ⅱ型PVTT可切除HCC。新辅助治疗方案包括酪氨酸激酶抑制剂(TKI),程序性死亡1(PD-1)抗体和经动脉化疗栓塞(TACE)。比较短期和长期结果。进行倾向评分匹配(PSM)以最小化潜在混杂因素的影响。
    33例患者接受了新辅助治疗,105例患者接受了单独手术。在新辅助治疗组中,7例(21.2%)患者病情稳定,13(39.4%)达到部分反应,13(39.4%)达到完全反应,基于改良的实体瘤反应评估标准。通过PSM,新辅助治疗减少了微血管侵犯(24.1%vs50.0%,P=0.021),卫星结节(6.9%对24.1%,P=0.036),甲胎蛋白>20(ng/mL)的患者较少(37.9%vs69.0%,P=0.006)。新辅助治疗减少了肿瘤复发并延长了生存期。多因素分析发现,新辅助治疗是总生存期和无复发生存期的独立保护因素。
    新辅助治疗为I/II型PVTT的HCC患者提供了一种有希望的治疗选择。
    UNASSIGNED: Hepatectomy could provide better survival benefit for hepatocellular carcinoma (HCC) with type I/II portal vein tumor thrombosis (PVTT). However, the postoperative recurrence remains high. We discussed whether neoadjuvant therapy could reduce HCC recurrence for these patients.
    UNASSIGNED: One hundred and thirty-eight resectable HCC with type I-II PVTT were retrospectively included. The neoadjuvant therapy regimens included tyrosine kinase inhibitor (TKI), programmed death 1(PD-1) antibodies and transarterial chemoembolization (TACE). Short-term and long-term outcomes were compared. Propensity score matching (PSM) was performed to minimize the influence of potential confounders.
    UNASSIGNED: Thirty-three patients underwent neoadjuvant therapy and 105 patients underwent surgery alone. In the neoadjuvant group, 7 (21.2%) patients achieved stable disease, 13 (39.4%) achieved partial response and 13 (39.4%) achieved complete response based on the modified Response Evaluation Criteria in Solid Tumors criterion. By PSM, the neoadjuvant therapy resulted in less microvascular invasion (24.1% vs 50.0%, P=0.021), satellite nodule (6.9% vs 24.1%, P=0.036) and less patients with alpha-fetoprotein>20(ng/mL) (37.9% vs 69.0%, P=0.006). The neoadjuvant therapy reduced tumor recurrence and prolonged survival. Multivariate analysis found that neoadjuvant therapy was an independent protective factor for overall survival and recurrence free survival.
    UNASSIGNED: Neoadjuvant treatment presents a promising treatment option for HCC patients with type I/II PVTT.

    目的:自身免疫性肝病(AILD)是肝细胞癌(HCC)的罕见病因。关于抗肿瘤疗法的疗效和耐受性的数据很少。这项泛欧洲研究旨在评估酪氨酸激酶抑制剂(TKIs)或经动脉化疗栓塞(TACE)治疗的AILD-HCC患者与更常见的HCC病因患者相比的结果。包括病毒,酒精性或非酒精性脂肪性肝病。
    方法:纳入了1996年至2020年在13个欧洲中心治疗的107例HCC-AILD(AIH:55;PBC:52)患者。65人接受TACE治疗,28人接受TKI治疗。43(66%)为女性(中位年龄73岁),患有HCC肿瘤BCLCA期(34%),B(46%),C(9%)或D(11%)。对于每种治疗类型,倾向评分匹配用于在1:1的基础上匹配AILD与非AILD-HCC,在130名TACE和56名TKI患者的最后队列中,对中位总生存期(mOS)和治疗耐受性进行比较分析.
    结果:HCC-AILD患者在两种TACE治疗中均显示出与对照组相当的mOS(19.5vs22.1个月,p=0.9)和TKI(15.4对15.1个月,p=0.5)。AILD-HCC患者的不良事件发生率低于对照组(33%vs62%,p=0.003)。对于TKIs,不良事件无显著差异(73%vs.86%,p=0.2)或中断率(44%与36%,p=0.7)。
    结论:总之,这项研究证明了接受局部和全身治疗的AILD-HCC患者的MOS相当,具有比其他原因的HCC更好的耐受性。TKIs仍然是AILD-HCC患者的重要治疗选择,特别是考虑到他们被排除在最近的免疫治疗试验之外。
    OBJECTIVE: Autoimmune liver diseases (AILD) are rare causes hepatocellular carcinoma (HCC), and data on the efficacy and tolerability of anti-tumor therapies are scarce. This pan-European study aimed to assess outcomes in AILD-HCC patients treated with tyrosine kinase inhibitors (TKIs) or transarterial chemoembolization (TACE) compared with patients with more common HCC etiologies, including viral, alcoholic or non-alcoholic fatty liver disease.
    METHODS: 107 patients with HCC-AILD (AIH:55; PBC:52) treated at 13 European centres between 1996 and 2020 were included. 65 received TACE and 28 received TKI therapy. 43 (66 %) were female (median age 73 years) with HCC tumor stage BCLC A (34 %), B (46 %), C (9 %) or D (11 %). For each treatment type, propensity score matching was used to match AILD to non-AILD-HCC on a 1:1 basis, yielding in a final cohort of 130 TACE and 56 TKI patients for comparative analyses of median overall survival (mOS) and treatment tolerability.
    RESULTS: HCC-AILD patients showed comparable mOS to controls for both TACE (19.5 vs. 22.1 months, p = 0.9) and TKI (15.4 vs. 15.1 months, p = 0.5). Adverse events were less frequent in AILD-HCC patients than controls (33 % % vs. 62 %, p = 0.003). For TKIs, there were no significant differences in adverse events (73% vs. 86%, p = 0.2) or interruption rates (44% vs. 36 %, p = 0.7).
    CONCLUSIONS: In summary, this study demonstrates comparable mOS for AILD-HCC patients undergoing local and systemic treatments, with better tolerability than HCC of other causes. TKIs remain important therapeutic options for AILD-HCC patients, particularly given their exclusion from recent immunotherapy trials.

    这项研究的目的是报告通过肝内动脉联合经动脉放射栓塞(TARE)和通过肝外供血动脉(EHFA)联合经动脉化疗栓塞(TACE)的安全性和肿瘤反应率肝细胞癌(HCC)。
    肝癌患者,在介入前多相CT上可见肝内和肝外动脉供应,并在2016年至2021年之间对同一结节进行TACE和TARE联合治疗,被回顾性地包括在内。流行病学,临床,生物,并记录了放射学特征。在6个月时评估安全性和肿瘤反应。
    9名患者(8名男性,中位年龄62岁[IQR:54-72岁])。7名患者先前对目标结节进行过治疗(TARE:5;TACE:2)。病变的中长轴(LA)为70mm(IQR:60-79mm)。3例患者有门静脉侵犯(VP3)。EHFA起源于右膈动脉(n=6),右肾上腺动脉(n=2),胃左动脉(n=1)。用TACE处理的肿瘤部分的LA为47mm(范围:35-64mm)。整个病变的LA与用TACE治疗的LA之间的比率为1.44(范围:1.27-1.7)。发生了一种主要并发症:慢性急性肝衰竭。中位随访时间为23个月(范围:16-29个月)。7例患者接受了进一步治疗:在同一病变上(n=2),在新出现的结节(n=2)上,和全身治疗(n=3)。在6个月的随访中,7例患者表现出局部客观反应.进展时间为13(3.5-19)个月。
    TARE和肝外TACE联合治疗肝癌,肝内和肝外动脉供应似乎是可行和安全的。需要进一步的研究来验证这些初步结果的有效性。
    UNASSIGNED: The aim of this study was to report the safety and tumor response rate of combined transarterial radioembolization (TARE) through the intrahepatic arteries and transarterial chemoembolization (TACE) through the extrahepatic feeding arteries (EHFA) in patients with hepatocellular carcinoma (HCC).
    UNASSIGNED: Patients with HCC, who had both intrahepatic and extrahepatic arterial supply visible on preinterventional multiphase CT and were treated between 2016 and 2021 with a combination of TACE and TARE on the same nodule, were retrospectively included. Epidemiological, clinical, biological, and radiological characteristics were recorded. Safety and tumor response were assessed at 6 months.
    UNASSIGNED: Nine patients (8 men, median age 62 years [IQR: 54-72 years]) were included. Seven patients had previous treatments on the target nodule (TARE: 5; TACE: 2). The median longest axis (LA) of the lesion was 70 mm (IQR: 60-79 mm). Three patients had portal vein invasion (VP3). The EHFA originated from the right diaphragmatic artery (n = 6), the right adrenal artery (n = 2), and the left gastric artery (n = 1). The LA of the tumor portion treated with TACE was 47 mm (range: 35-64 mm). The ratio between the LA of the entire lesion and the LA treated with TACE was 1.44 (range: 1.27-1.7). One major complication occurred: acute on chronic liver failure. Median follow-up was 23 months (range: 16-29 months). Seven patients underwent further treatment: on the same lesion (n = 2), on newly appeared nodules (n = 2), and systemic treatment (n = 3). At 6-month follow-up, seven patients showed a local objective response. Time-to-progression was 13 (3.5-19) months.
    UNASSIGNED: The combination of TARE and extrahepatic TACE for HCC with both intrahepatic and extrahepatic arterial supplies seems feasible and safe. Further studies are needed to validate the effectiveness of these preliminary results.

    目的:日本介入肿瘤学组(JIVROSG)显示了非选择性经肝动脉化疗栓塞(TACE)用顺铂细粉(二氨基二氯铂;DDP-H)(65mg/m2)和不含碘油的多孔明胶颗粒(DDP-HTACE)治疗广泛的多灶性肝细胞癌(HCC)的有效性和安全性。然而,在JIVROSG研究之后,没有关于这种方法的研究。因此,我们旨在评估这种新型DDP-HTACE的疗效及其对肝功能的影响.
    方法:我们回顾性回顾了TACE初治多灶性HCC患者的病历(Child-PughA级,多达七个,没有系统治疗史),在2006年1月至2019年12月期间接受了全肝DDP-HTACE。
    结果:本研究纳入60例患者。患者的中位年龄为71岁(范围,35-88)年。肿瘤的最大尺寸中位数为26(范围,8-184)毫米;86.7%的患者符合多达11个标准。总生存期为30.3个月。在初步评估时(中位数,45天),总缓解率为65.0%;根据实体肿瘤指南中改良的缓解评估标准,疾病控制率为86.7%.尽管9例患者的肝功能在初步评估时已恶化至Child-PughB级,其中6例恢复到Child-PughA级。只有3例患者(5%)表现出永久性肝功能受损。
    结论:全肝DDP-HTACE无碘油或珠可有效减少肿瘤并保留肝功能。
    OBJECTIVE: The Japanese Interventional oncology group (JIVROSG) showed the efficacy and safety of nonselective transarterial chemoembolization (TACE) with fine cisplatin powder (diamminedichloroplatinum; DDP-H) (65 mg/m2) and porous gelatin particles (DDP-H TACE) without lipiodol for extensive multifocal hepatocellular carcinoma (HCC). However, there are no studies on this method following the JIVROSG study. Therefore, we aimed to evaluate the efficacy of this new DDP-H TACE and its effect on liver function.
    METHODS: We retrospectively reviewed the medical records of TACE-naïve patients with multifocal HCC (Child-Pugh class A, up-to-seven out, no prior history of systemic therapy) who underwent whole-liver DDP-H TACE between January 2006 and December 2019.
    RESULTS: Sixty patients were included in this study. The median age of the patients was 71 (range, 35-88) years. The median maximum size of tumors was 26 (range, 8-184) mm; 86.7% of patients met the up-to-11 criteria out. The overall survival duration was 30.3 months. At the time of initial evaluation (median, 45 days), the overall response rate was 65.0%; the disease control rate was 86.7% based on the modified response evaluation criteria in solid tumors guideline. Although nine patients\' liver function had deteriorated to Child-Pugh class B at initial evaluation, six of them recovered to Child-Pugh class A. Only three patients (5%) showed permanently impaired liver function.
    CONCLUSIONS: Whole-liver DDP-H TACE without lipiodol or beads effectively reduced tumors and preserved liver function.

    背景:肝细胞癌(HCC)是癌症相关死亡率的主要原因,经肝动脉化疗栓塞术(TACE)是治疗中期HCC患者的既定技术。这项研究的目的是在澳大利亚环境中生成cTACE和DEB-TACE的准确成本计算数据,并评估其中一项程序是否具有良好的成本效益。
    方法:使用2018年1月至2022年12月在单个中心进行的所有TACE程序的数据进行成本研究。数据包括所有直接和间接成本,包括运营成本,工资,开销,病房费用,输血,病理学,药房和病房支持。通过将当地成本除以现有的质量调整寿命年(QALY)高质量数据来评估成本效益。
    结果:对44例患者进行了64次TACE治疗。平均年龄为66.5岁,91%为男性。对于整个TACE治疗方案,每位患者的总体总费用中位数为AUD$7380(范围AUD$3719-$20,258)。然而,39%的患者接受了一种以上的治疗,每个单独治疗的中位费用为AUD$5270(范围AUD$3533-$15,818)。cTACE(AUD$4978)和DEB-TACE(AUD$9202)之间的中位成本差异显着,P<0.001。在计算成本效益时,每次cTACE治疗的成本为每QALY2489澳元,而每个DEB-TACE的成本为每QALY3834澳元。DEB-TACE相对于cTACE的增量成本效益比(ICER)为每QALY获得10,560澳元。
    结论:在澳大利亚,cTACE和DEB-TACE都是低成本的治疗方法。然而,DEB-TACE提供的解决方案为每QALY获得10,560澳元的ICER,低于澳大利亚政府愿意支付的门槛,因此是一种更具成本效益的治疗方法。
    BACKGROUND: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality and transarterial chemoembolisation (TACE) is an established technique to treat patients with intermediate-stage HCC. The aim of this study was to generate accurate costing data on cTACE and DEB-TACE in an Australian setting and assess whether one of the procedures offers favourable cost-effectiveness.
    METHODS: Costing study using data from all TACE procedures performed at a single centre between January 2018 and December 2022. Data were included from all direct and indirect costs including operative costs, wages, overheads, ward costs, transfusion, pathology, pharmacy and ward support. Cost-effectiveness was assessed by dividing local costs by existing high-quality data on quality-adjusted life years (QALYs).
    RESULTS: 64 TACE treatments were performed on 44 patients. Mean age was 66.5 years and 91% were male. Overall median total cost per patient for the entire TACE treatment regime was AUD$7380 (range AUD$3719-$20,258). However, 39% of patients received more than one treatment, and the median cost per individual treatment was AUD$5270 (range AUD$3533-$15,818). The difference in median cost between cTACE (AUD$4978) and DEB-TACE (AUD$9202) was significant, P < 0.001. In calculating cost-effectiveness, each cTACE treatment cost AUD$2489 per QALY gained, while each DEB-TACE cost AUD$3834 per QALY gained. The incremental cost-effectiveness ratio (ICER) for DEB-TACE over cTACE was AUD$10,560 per QALY gained.
    CONCLUSIONS: Both cTACE and DEB-TACE are low-cost treatments in Australia. However, DEB-TACE offers a solution with an ICER of AUD$10,560 per QALY gained which is below the Australian government willingness to pay threshold and thus is a more cost-effective treatment.

    目前治疗不可切除肝癌的标准是经动脉化疗栓塞术(TACE)。其中涉及使用化疗颗粒选择性地栓塞供肝肿瘤的动脉。复杂的细血管的准确体积识别对于选择性栓塞至关重要。三维成像,特别是锥形束CT(CBCT),在这种高度可变的解剖结构中,有助于小血管的可视化和靶向,但是较长的图像采集时间会导致扫描中的患者运动,扭曲血管结构和组织边界。为了提高血管解剖结构的清晰度和手术中的实用性,这项工作提出了一个有针对性的运动估计和补偿框架,消除了任何先验信息或外部跟踪和用户交互的需要。在两个阶段中执行运动估计:(i)目标识别阶段,其使用多视图卷积神经网络在投影域中分割动脉和导管以构建粗3D血管掩模;以及(ii)目标运动估计阶段,其经由在目标血管掩模上计算的血管增强目标函数的优化来迭代求解时变运动场。血管增强目标是通过局部图像Hessian的特征值得出的,以强调明亮的管状结构。运动补偿是通过空间变换器算子实现的,这些算子将时间相关的变形应用于部分角度重建,允许通过梯度反向传播有效的最小化。该框架在模拟肝肿瘤TACE的解剖学逼真的模拟运动破坏的CBCT中进行了训练和评估,在中等(3.0毫米)和大(6.0毫米)的运动幅度。运动补偿显著改善了中位血管DICE评分(对于大运动,从0.30到0.59),图像SSIM(大运动从0.77到0.93),和血管锐度(0.189mm-1到0.233mm-1的大运动)在模拟情况下。在临床介入性CBCT上,运动补偿还显示出血管锐度增加(之前为0.188mm-1,之后为0.205mm-1)和重建的血管长度(中位数从37.37mm增加到41.00mm)。提出的解剖感知运动补偿框架提出了一种有希望的方法,用于提高CBCT用于过程中血管成像的实用性。促进选择性栓塞程序。
    The present standard of care for unresectable liver cancer is transarterial chemoembolization (TACE), which involves using chemotherapeutic particles to selectively embolize the arteries supplying hepatic tumors. Accurate volumetric identification of intricate fine vascularity is crucial for selective embolization. Three-dimensional imaging, particularly cone-beam CT (CBCT), aids in visualization and targeting of small vessels in such highly variable anatomy, but long image acquisition time results in intra-scan patient motion, which distorts vascular structures and tissue boundaries. To improve clarity of vascular anatomy and intra-procedural utility, this work proposes a targeted motion estimation and compensation framework that removes the need for any prior information or external tracking and for user interaction. Motion estimation is performed in two stages: (i) a target identification stage that segments arteries and catheters in the projection domain using a multi-view convolutional neural network to construct a coarse 3D vascular mask; and (ii) a targeted motion estimation stage that iteratively solves for the time-varying motion field via optimization of a vessel-enhancing objective function computed over the target vascular mask. The vessel-enhancing objective is derived through eigenvalues of the local image Hessian to emphasize bright tubular structures. Motion compensation is achieved via spatial transformer operators that apply time-dependent deformations to partial angle reconstructions, allowing efficient minimization via gradient backpropagation. The framework was trained and evaluated in anatomically realistic simulated motion-corrupted CBCTs mimicking TACE of hepatic tumors, at intermediate (3.0 mm) and large (6.0 mm) motion magnitudes. Motion compensation substantially improved median vascular DICE score (from 0.30 to 0.59 for large motion), image SSIM (from 0.77 to 0.93 for large motion), and vessel sharpness (0.189 mm-1 to 0.233 mm-1 for large motion) in simulated cases. Motion compensation also demonstrated increased vessel sharpness (0.188 mm-1 before to 0.205 mm-1 after) and reconstructed vessel length (median increased from 37.37 to 41.00 mm) on a clinical interventional CBCT. The proposed anatomy-aware motion compensation framework presented a promising approach for improving the utility of CBCT for intra-procedural vascular imaging, facilitating selective embolization procedures.

    背景:CRAFITY评分是诊断为肝细胞癌(HCC)并接受阿特珠单抗和贝伐单抗(Atez/Bev)治疗的个体的简单有效的预测模型。然而,尚无大样本量研究报道CRAFITY评分在联合应用经肝动脉化疗栓塞(TACE)的HCC患者中的应用.这项研究旨在评估CRAFITY评分在接受TACE联合lenvatinib的HCC患者中的预后作用。
    方法:这项回顾性分析涵盖了2019年8月至2022年8月在中国两家医疗机构接受TACE和lenvatinib联合治疗的314例HCC患者(包括n=172的培训队列和n=142的验证队列)。我们调查了总生存期(OS)的预后价值,无进展生存期(PFS),疾病控制率,和基于CRAFITY评分的训练队列中的客观应答率。此外,通过使用外部队列进行验证,证实了模型的预测能力.
    结果:我们在训练和验证队列中纳入了174和142例接受TACE联合来伐替尼治疗的患者,相应地。在所有培训和验证队列中,所有三组的PFS和OS都不同,基于CRAFITY评分(p<0.001)。在这两个队列中,CRAFITY评分可有效预测肿瘤反应(p<0.001)。此外,在接受TACE治疗的121名患者中,lenvatinib,和免疫疗法,CRAFITY评分在PFS和OS方面显示出良好的预测功效.
    结论:残酷评分,利用C反应蛋白和甲胎蛋白值,作为预测TACE加lenvatinib在不可切除HCC患者中的有效性的可靠和实用的工具。这种评分系统有可能帮助肿瘤学家做出明智的临床决定。
    BACKGROUND: The CRAFITY score serves as a simple and effective predictive model for individuals diagnosed with hepatocellular carcinoma (HCC) and subjected to treatment with atezolizumab and bevacizumab (Atez/Bev). However, no large sample size studies have reported the application of the CRAFITY score among HCC patients undergoing transarterial chemoembolization (TACE) in conjunction with lenvatinib. This research aims to assess the prognostic role of the CRAFITY score in the context of individuals with HCC receiving TACE in combination with lenvatinib.
    METHODS: This retrospective analysis encompassed 314 individuals diagnosed with HCC who underwent the combination of TACE and lenvatinib at two medical facilities in China from August 2019 to August 2022 (comprising a training cohort of n = 172 and a validation cohort of n = 142). We investigated the prognostic values of overall survival (OS), progression-free survival (PFS), disease control rate, and objective response rate in the training cohort based on the CRAFITY scores. Furthermore, the predictive capacity of the model was corroborated through validation using an external cohort.
    RESULTS: We included 174 and 142 patients treated with TACE plus lenvatinib in the training and validation cohorts, correspondingly. PFS and OS differed across all three groups in all training and validation cohorts, based on the CRAFITY score (p < 0.001). In both cohorts, the CRAFITY score effectively predicted tumor response (p < 0.001). Moreover, among the 121 patients who received TACE, lenvatinib, and immunotherapy, the CRAFITY score showed promising predictive efficacy in PFS and OS.
    CONCLUSIONS: The CRAFITY score, utilizing C-reactive protein and alpha-fetoprotein values, emerges as a dependable and pragmatic instrument for forecasting the effectiveness of TACE plus lenvatinib in individuals with unresectable HCC. This scoring system holds the potential to assist oncologists in making informed clinical decisions.
