Introduction: While combination of stereotactic body radiotherapy (SBRT) and immunotherapy are promising, their efficacy and safety have not been compared with SBRT-alone in patients with unresectable hepatocellular carcinoma (HCC). Methods: This retrospective study included 100 patients with nonmetastatic, unresectable HCC in two hospitals. Eligible patients had tumor nodules ≤3 and Child-Pugh liver function score of A5 to B7. Seventy patients received SBRT-alone, and 30 patients underwent combined SBRT and immunotherapy (SBRT-IO). Overall survival (OS), time to progression (TTP), overall response rate (ORR), and toxicity were analyzed. We adjusted for the potential confounding factors using propensity score matching. Results: The median tumor size was 7.3 cm (range, 2.6–18 cm). Twenty-five (25%) of patients had vascular invasion. Before propensity score matching, the 1-year and 3-year OS rate was 89.9% and 59.8% in the SBRT-IO group and 75.7% and 42.3% in SBRT-alone group (p = 0.039). After propensity score matching (1:2), 25 and 50 patients were selected from the SBRT-IO and SBRT-alone group. The 1-year and 3-year OS was 92.0% and 63.9% in the SBRT-IO group versus 74.0% and 43.3% in the SBRT-alone group (p = 0.034). The 1-year and 3-year TTP was better in SBRT-IO group (1-year: 68.9% vs. 58.9% and 3-year: 61.3% vs. 32.5%, p = 0.057). The ORR of 88% (complete response [CR]: 56%, partial response [PR]: 22%) in SBRT-IO arm was significantly better than 50% (CR: 20%, PR: 30%) in the SBRT-alone arm (p = 0.006). Three patients (12%) developed ≥grade 3 immune-related treatment adverse events (n = 2 hepatitis, n = 1 dermatitis) leading to permanent treatment discontinuation. Conclusion: Adding immunotherapy to SBRT resulted in better survival with manageable toxicities. Prospective randomized trial is warranted.

Introduction: Intratumoral administration of pexa-vec (pexastimogene devacirepvec), an oncolytic and immunotherapeutic vaccinia virus, given to patients with hepatocellular carcinoma (HCC), is associated with both local and distant tumor responses. We hypothesized subsequent treatment with sorafenib could demonstrate superior efficacy. Methods: This random phase III open-label study evaluated the sequential treatment with pexa-vec followed by sorafenib compared to sorafenib in patients with advanced HCC and no prior systemic treatment. The primary endpoint is overall survival (OS). Key secondary endpoints included time to progression (TTP), progression-free survival, overall response rate (ORR), and disease control rate (DCR). Safety was assessed in all patients who received ≥1 dose of study treatment. Results: The study was conducted at 142 sites in 16 countries. From December 30, 2015, to the interim analysis on August 2, 2019, 459 patients were randomly assigned (pexa-vec plus sorafenib: 234, sorafenib: 225). At the interim analysis, the median OS was 12.7 months (95% CI: 9.89, 14.95) in the pexa-vec plus sorafenib arm and 14.0 months (95% CI: 11.01, 18.00) in the sorafenib arm. This led to the early termination of the study. The median TTP was 2.0 months (95% CI: 1.77, 2.96) and 4.2 months (95% CI: 2.92, 4.63); ORR was 19.2% (45 patients) and 20.9% (47 patients); and DCR was 50.0% (117 patients) and 57.3% (129 patients) in the pexa-vec plus sorafenib and sorafenib arms, respectively. Serious adverse events were reported in 117 (53.7%) patients in the pexa-vec plus sorafenib and 77 (35.5%) patients in the sorafenib arm. Liver failure was the most frequently reported in both groups. Conclusion: Sequential pexa-vec plus sorafenib treatment did not demonstrate increased clinical benefit in advanced HCC and fared worse compared to sorafenib alone. The advent of the added value of checkpoint inhibitors should direct any further development of oncolytic virus therapy strategies.
简介对肝细胞癌(HCC)患者进行pexa-vec(pexastimogene devacirepvec)(一种溶瘤和免疫治疗疫苗病毒)瘤内给药,可产生局部和远处肿瘤反应。我们假设,随后使用索拉非尼治疗可显示出更优越的疗效。研究方法这项随机III期开放标签研究评估了晚期HCC患者使用pexa-vec后再使用索拉非尼与索拉非尼进行序贯治疗的疗效比较。主要终点是总生存期(OS)。主要次要终点包括进展时间(TTP)、无进展生存期、总反应率(ORR)和疾病控制率(DCR)。对所有接受≥1次研究治疗的患者进行安全性评估。研究结果该研究在16个国家的142个地点进行。从2015年12月30日到2019年8月2日的中期分析,459名患者被随机分配(pexa-vec加索拉非尼:234人,索拉非尼:225人)。在中期分析中,pexa-vec 加索拉非尼治疗组的中位 OS 为 12.7 个月(95% CI:9.89,14.95),索拉非尼治疗组的中位 OS 为 14.0 个月(95% CI:11.01,18.00)。这导致研究提前结束。佩沙韦克加索拉非尼治疗组和索拉非尼治疗组的中位TTP分别为2.0个月(95% CI:1.77,2.96)和4.2个月(95% CI:2.92,4.63);ORR分别为19.2%(45例患者)和20.9%(47例患者);DCR分别为50.0%(117例患者)和57.3%(129例患者)。pexa-vec加索拉非尼治疗组和索拉非尼治疗组分别有117例(53.7%)和77例(35.5%)患者报告了严重不良事件。肝功能衰竭是两组中最常见的不良反应。结论pexa-vec联合索拉非尼的序贯治疗并没有增加晚期HCC的临床获益,而且与单独使用索拉非尼相比效果更差。检查点抑制剂附加价值的出现应指导溶瘤病毒治疗策略的进一步发展。

Introduction: Lenvatinib is indicated for the forefront treatment of advanced hepatocellular carcinoma (aHCC), but its use may be limited by the risk of esophagogastric varices (EGV) bleeding. This study assessed the prevalence, predictors, and complications of EGV in aHCC patients treated with lenvatinib. Methods: In this multicenter international retrospective study, cirrhotic patients treated with lenvatinib for aHCC, were enrolled if upper-gastrointestinal endoscopy was available within 6 months before treatment. Primary endpoint was the incidence of EGV bleeding during lenvatinib therapy; secondary endpoints were predictors for EGV bleeding, prevalence, and risk factors for the presence of EGV and high-risk EGV at baseline, as well as impact of EGV bleeding on patients’ survival. Results: 535 patients were enrolled in the study (median age: 72 years, 78% male, 63% viral etiology, 89% Child-Pugh A, 16% neoplastic portal vein thrombosis [nPVT], 56% Barcelona Clinic Liver Cancer-C): 234 had EGV (44%), 70 (30%) were at high risk and 59 were on primary prophylaxis. During lenvatinib treatment, 17 patients bled from EGV (3 grade 5), the 12-month cumulative incidence being 3%. The only baseline independent predictor of EGV bleeding was the presence of baseline high-risk EGV (hazard ratio: 6.94, 95% confidence interval [CI]: 2.23–21.57, p = 0.001). In these patients the 12-month risk was 17%. High-risk varices were independently associated with Child-Pugh B score (odds ratio [OR]: 2.12; 95% CI: 1.08–4.17, p = 0.03), nPVT (OR: 2.54; 95% CI: 1.40–4.61, p = 0.002), and platelets &lt;150,000/μL (OR: 2.47; 95% CI: 1.35–4.50, p = 0.003). Conclusion: In hepatocellular carcinoma patients treated with lenvatinib, the risk of EGV bleeding was mostly low but significant only in patients with high-risk EGV at baseline.

Introduction: The incidence of hepatocellular carcinoma (HCC) in Budd-Chiari syndrome (BCS) is unknown and there is no validated diagnostic work-up to define the liver nodules with arterial phase hyperenhancement (APHE), suggesting malignancy. This prospective study evaluates HCC incidence in a Western cohort of patients with BCS and assesses the performance of MRI with hepatobiliary contrast (HB-MRI) for nodule characterization. Methods: Patients with BCS followed in our hospital were prospectively evaluated by MRI with extracellular contrast (EC-MRI). Nodules with APHE categorized as non-conclusively benign by 2 radiologists were studied by HB-MRI and reviewed by 2 radiologists blinded to the EC-MRI results. A new EC-MRI 1 year later and clinical, analytical, and sonographic follow-up every 6 months for a median of 10 years was performed. Results: A total of 55 non-conclusively benign nodules with APHE were detected at EC-MRI in 41 patients. While 32 of them were suggestive of HCC by EC-MRI, all the 55 nodules showed increased uptake of hepatobiliary contrast. An unequivocal central scar was seen in 12/55 nodules at HB-MRI regardless of it was not detected on the EC-MRI. None of the nodules was hypointense in the hepatobiliary phase (HBP). HCC was not detected during a median of 10 years of follow-up. Conclusions: Detection of nodules with APHE is frequent in patients with BCS, but HCC is rare in Western patients with BCS. While EC-MRI may detect nodules suggesting malignancy, the identification of contrast uptake in the HBP at HB-MRI may help categorize them as benign.

Introduction: Proteinuria is one of the adverse events of atezolizumab plus bevacizumab combination therapy (Atezo + Bev) and can cause interruption in the use of Bev. However, the risk factors for proteinuria in patients with hepatocellular carcinoma (HCC) who are receiving Atezo + Bev have not yet been investigated. The aim of this study was to identify the risk factors for early onset of proteinuria in Atezo + Bev for patients with unresectable HCC.

Methods: Sixty-four patients with Child-Pugh scores of 5-7, an Eastern Cooperative Oncology Group performance status of 0 or 1, and low level of proteinuria (1+ or less on a dipstick test and urine protein-to-creatinine ratio (UPCR) less than 2.0 g/g Cr) at the initiation of therapy were analyzed. The level of proteinuria was evaluated based on the Common Terminology Criteria for Adverse Events version 5.0. We adopted the UPCR for the quantitative test instead of a 24-h urine collection. The incidence of proteinuria and changes in liver function were retrospectively investigated.

Results: The cumulative incidence of proteinuria over a 24-week period was 34.4%. Multivariate analysis showed that a low estimated glomerular filtration rate (hazard ratio [HR], 3.807; 95% confidence interval [CI], 1.579-9.180; p = 0.003), treatment for hypertension (HR, 6.224; 95% CI, 1.614-24.010; p = 0.008), and high systolic blood pressure (SBP) (HR, 2.649; 95% CI, 1.133-6.194; p = 0.025) were risk factors for proteinuria. Serum albumin levels and albumin-bilirubin scores in patients with proteinuria worsened. In addition, a mean SBP ≥135 mm Hg during treatment was the only risk factor for the development of severe proteinuria (UPCR >2 g/g Cr).

Conclusion: Our study found that controlling blood pressure is extremely important for the management of proteinuria in patients with HCC who are receiving Atezo + Bev.

导语:蛋白尿是atezolizumab + bevacizumab联合治疗(Atezo + Bev)的不良事件之一,可导致Bev的使用中断。然而,接受Atezo + Bev治疗的肝细胞癌(HCC)患者发生蛋白尿的危险因素尚未得到研究。本研究的目的是确定不可切除HCC患者Atezo + Bev中早发性蛋白尿的危险因素。方法:对64例Child-Pugh评分为5-7分,东部肿瘤合作组表现状态为0或1分,治疗开始时尿蛋白水平低(试纸试验1+及以下,尿蛋白与肌酐比(UPCR)小于2.0 g/g Cr)的患者进行分析。蛋白尿水平根据不良事件通用术语标准5.0版进行评估。我们采用UPCR进行定量测试,而不是24小时尿液收集。回顾性调查蛋白尿的发生率和肝功能的变化。结果:24周内蛋白尿的累积发生率为34.4%。多因素分析显示肾小球滤过率估计较低(风险比[HR], 3.807;95%置信区间[CI], 1.579-9.180;p = 0.003),高血压治疗(HR, 6.224;95% ci, 1.614-24.010;p = 0.008)、高收缩压(SBP) (HR, 2.649;95% ci, 1.133-6.194;P = 0.025)是蛋白尿的危险因素。蛋白尿患者血清白蛋白水平和白蛋白-胆红素评分恶化。此外,治疗期间平均收缩压≥135 mm Hg是发展为严重蛋白尿(UPCR > 2g /g Cr)的唯一危险因素。结论:我们的研究发现,控制血压对于接受Atezo + Bev治疗的HCC患者蛋白尿的管理至关重要。

Background/aim: There is no known report regarding the relationship of atezolizumab plus bevacizumab (Atez/Bev) treatment with muscle volume loss (MVL) in unresectable hepatocellular carcinoma (u-HCC) patients. This study aimed to elucidate the clinical relationship between MVL and Atez/Bev.

Materials/methods: From September 2020 to December 2021, 229 u-HCC patients treated with Atez/Bev and with muscle volume data obtained by computed tomography at the baseline available were analyzed (median age, 74 years; males, 186 (81.2%); ECOG PS 0/1, 221 (96.5%); HCV:HBV:alcohol:others = 81:33:40:75; Child-Pugh A, 212 (92.6%); modified albumin-bilirubin (mALBI) grade 1:2a:2b = 79:60:90; BCLC 0:A:B:C = 1:24:87:117; median observation period, 6.8 months). Japan Society of Hepatology criteria were used for definition of MVL and prognostic factors were retrospectively evaluated.

Results: Multivariate Cox-hazard analysis of prognostic factors for progression-free survival (PFS) showed elevated alpha-fetoprotein (AFP) (≥100 ng/mL) (HR 1.848, 95% CI 1.264-2.702, p = 0.002), mALBI grade (≥2a) (HR 1.563, 95% CI 1.035-2.359, p = 0.034), and MVL (HR 1.479, 95% CI 1.020-2.144, p = 0.039) as significant factors. For overall survival (OS), significant factors included elevated AFP (≥100 ng/mL) (HR 3.564, 95% CI 1.856-6.844, p < 0.001), mALBI grade (≥2a) (HR 3.451, 95% CI 1.580-7.538, p = 0.002), and MVL (HR 2.119, 95% CI 1.150-3.904, p = 0.016). Patients with MVL (MVL group, n = 91) showed worse PFS than those without (non-MVL group, n = 138) (median PFS 5.3 vs. 7.6 months, p = 0.025), while the MVL group showed worse OS (p = 0.038), though neither reached the median survival time.

Conclusion: MVL may be a clinical factor related to poor prognosis in patients receiving Atez/Bev treatment for u-HCC.

背景/目的:在不可切除的肝细胞癌(u-HCC)患者中,atezolizumab加贝伐单抗(Atez/Bev)治疗与肌肉体积损失(MVL)的关系尚无已知的报道。本研究旨在阐明MVL与Atez/Bev的临床关系。材料/方法:从2020年9月至2021年12月,229例u-HCC患者接受Atez/Bev治疗,并在基线时通过计算机断层扫描获得肌肉体积数据(中位年龄,74岁;男性186人(81.2%);Ecog ps 0/ 1,221 (96.5%);HCV:HBV:酒精:其他= 81:33:40:75;Child-Pugh A, 212 (92.6%);改性白蛋白-胆红素(mALBI)分级1:2a:2b = 79:60:90;BCLC 0: a: b: c = 1:24:87:117;中位观察期为6.8个月)。采用日本肝病学会的标准定义MVL,并对预后因素进行回顾性评估。结果:多因素Cox-hazard分析无进展生存期(PFS)预后因素显示,甲胎蛋白(AFP)升高(≥100 ng/mL) (HR 1.848, 95% CI 1.264-2.702, p = 0.002)、mALBI分级(≥2a) (HR 1.563, 95% CI 1.035-2.359, p = 0.034)和MVL (HR 1.479, 95% CI 1.020-2.144, p = 0.039)为显著因素。对于总生存率(OS),显著因素包括AFP升高(≥100 ng/mL) (HR 3.564, 95% CI 1.856-6.844, p < 0.001)、mALBI分级(≥2a) (HR 3.451, 95% CI 1.580-7.538, p = 0.002)和MVL (HR 2.119, 95% CI 1.150-3.904, p = 0.016)。MVL患者(MVL组,n = 91)的PFS较无MVL患者(非MVL组,n = 138)差(中位PFS 5.3 vs. 7.6个月,p = 0.025),而MVL组的OS较差(p = 0.038),但均未达到中位生存时间。结论:MVL可能是u-HCC患者接受Atez/Bev治疗预后不良的一个临床因素。

Hepatic resection and radiofrequency ablation (RFA)/ microwave ablation are well-established curative treatments for hepatocellular carcinoma (HCC); however, the disease often recurs [1, 2]. Pathological studies of resected HCC specimens reported that microscopic intrahepatic metastases are present in about 10% of patients with a solitary HCC measuring 2 cm or less. Microvascular invasion is also present in about 27% of patients [3]. Based on these facts, it is believed that there is a certain risk of recurrence of intrahepatic metastasis, even for a single nodule measuring 2 cm or less. Furthermore, the larger the tumor, or the presence of multiple HCCs larger than 2 cm, increases the risk of intrahepatic metastasis and microvascular invasion, and therefore the risk of intrahepatic metastatic recurrence [4, 5]. There are two patterns of recurrence after curative treatment: early and late. Early recurrence involves mainly intrahepatic metastasis via the portal vein, while late recurrence has a more multicentric etiology [2]. About 80% of HCCs recur 5 years after RFA or resection [6]. The main reason for the poor prognosis associated with HCC is frequent recurrence, even after curative treatment. Repeated TACE to treat recurrence worsens liver function in many cases, resulting in death from liver failure. Conversely, if HCC recurrence after curative treatment can be suppressed, the prognosis should improve dramatically. Several adjuvant trials have been conducted to inhibit recurrence, but all yielded negative results [7–9]. To date, representative clinical trials of adjuvants that help to prevent recurrence include a trial of Vitamin K [7], the NIK-333 trial that used retinoid [8], and the STORM trial

Introduction: Intrahepatic cholangiocarcinoma (ICC) is a highly aggressive liver malignancy with poor prognosis. Recently, the development of immune checkpoint inhibitors (ICIs), such as programmed cell death 1 (PD-1) inhibitors, has emerged as a promising strategy in multiple tumor types, including ICC. Microsatellite instability-high (MSI-H) is an important biomarker for ICIs in solid tumors. The response rate in patients with MSI-H is significantly higher than in those with microsatellite stability/microsatellite instability-low. And approximately 80-90% of the patients with MSI-H could maintain sustained clinical benefits once they had an initial response. However, some patients could have primary resistance at the beginning, and some might have acquired resistance after long-term treatment.

Case presentation: We present the case of an ICC patient with MSI-H who suffered rapid progression after a short-term remission with camrelizumab, a kind of PD-1 inhibitor, as second-line treatment. The patient's genomic and immune features were analyzed by next-generation sequencing and multiplex immunofluorescence staining to explore the possible mechanisms of the rapidly acquired resistance of ICIs in this MSI-H case.

Conclusion: The genomic and immunohistochemical analysis showed that TGFBR2 mutation, loss of HLA B44 supertype, carrying B62 supertype, and increased PD-L1+ cells, macrophages, and Tregs in the tumor microenvironment might be related to the nonsustain benefit of ICIs in this MSI-H patient.

简介:肝内胆管癌(ICC)是一种高度侵袭性、预后差的肝脏恶性肿瘤。最近,免疫检查点抑制剂(ICIs)的发展,如程序性细胞死亡1 (PD-1)抑制剂,已经成为多种肿瘤类型(包括ICC)的一种有前途的策略。微卫星不稳定性高(Microsatellite instability-high, MSI-H)是实体肿瘤中ICIs的重要生物标志物。MSI-H患者的应答率明显高于微卫星稳定性/微卫星不稳定性-低的患者。大约80-90%的MSI-H患者一旦有了最初的反应,就能保持持续的临床获益。然而,一些患者在开始时可能有原发性耐药,一些患者可能在长期治疗后获得耐药。病例介绍:我们报告了一例伴有MSI-H的ICC患者,在接受camrelizumab(一种PD-1抑制剂)作为二线治疗的短期缓解后,病情迅速进展。通过新一代测序和多重免疫荧光染色分析患者的基因组和免疫特征,探讨该MSI-H病例中ICIs快速获得性耐药的可能机制。结论:基因组和免疫组化分析显示,TGFBR2突变、HLA B44超型缺失、携带B62超型、肿瘤微环境中PD-L1+细胞、巨噬细胞和Tregs增加可能与该MSI-H患者ICIs的非持续性获益有关。
