中期原发性肝癌临床治疗现状及进展
Current status and advances in the clinical management of intermediate-stage primary liver cancer
肝细胞癌是最常见的恶性肿瘤之一，严重威胁人民生命健康。中期肝癌以其涵盖范围宽及显著的异质性为特点，在分期优化和个性化治疗方面一直存在着较大争议。近年来随着局部治疗手段、系统治疗药物的不断发展以及在转化治疗、新辅助治疗和术后辅助治疗等治疗策略方面的研究突破，多学科联合治疗成为中期肝癌治疗的重要方向。中期肝癌的分期对制定个性化治疗方案和准确评估病人预后至关重要。全球范围内提出了多种肝癌分期系统，然而，对于中期肝癌的定义及其适用性一直存在争议，这促使研究者们不断优化分期系统以提高预后预测和疗效评估的准确性。在治疗方面，传统的经导管肝动脉栓塞化疗（TACE）是中期肝癌的主要治疗方式，但并非所有病人都能受益，且部分病人在多次TACE后出现耐药。近年来，肝切除术、肝动脉灌注化疗（HAIC）、选择性内放射治疗（SIRT）等局部治疗手段，以及靶向治疗和免疫治疗药物在中期肝癌中的应用取得了显著进展。肝切除术在中期肝癌治疗中的关键作用逐渐获得认可；HAIC在新辅助治疗中的应用显示出较好的疗效。SIRT在一些临床试验中展现出优于传统TACE的效果。此外，靶向治疗和免疫治疗的发展为中期肝癌病人带来了新的希望。索拉非尼、仑伐替尼等靶向药物，以及帕博利珠单抗、卡瑞利珠单抗等免疫检查点抑制剂在延长病人生存期方面展现出良好效果。联合治疗策略，如靶向药物与免疫治疗联合、局部治疗与系统治疗联合，逐渐成为研究热点，并在多项临床试验中取得了积极结果。未来，随着生物标记物和多组学分子分型技术的发展，中期肝癌的分期和治疗将更加精准和个性化。多学科综合治疗协作组（MDT）模式有助于整合不同学科的专业知识，为病人提供全面而精准的诊疗方案，提高治疗效果，延长病人生存期。
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, posing a serious threat to public health. Intermediate-stage HCC is characterized by its extensive coverage and significant heterogeneity, leading to considerable debate over staging optimization and personalized treatment. In recent years, advancements in local treatment methods, systemic therapy drugs, and breakthroughs in treatment strategies such as transformation therapy, neoadjuvant therapy, and postoperative adjuvant therapy have made multidisciplinary combined therapy a key direction for intermediate-stage HCC treatment. Staging of intermediate-stage HCC is crucial for developing personalized treatment plans and accurately assessing patient prognosis. Various staging systems for HCC have been proposed worldwide; however, there is ongoing controversy regarding the definition and applicability of intermediate-stage HCC. This has driven researchers to continuously optimize staging systems to improve prognostic prediction and therapeutic efficacy. In terms of treatment, traditional transarterial chemoembolization (TACE) has been the primary approach for intermediate-stage HCC, but not all patients benefit from it, and some develop resistance after multiple TACE sessions. Recently, significant progress has been made in the application of local treatments such as liver resection, hepatic arterial infusion chemotherapy (HAIC), and selective internal radiotherapy (SIRT), as well as targeted therapies and immunotherapies. The critical role of liver resection in the treatment of intermediate-stage HCC has gradually gained recognition; HAIC has shown promising efficacy in neoadjuvant therapy; SIRT has demonstrated superior results to traditional TACE in some clinical trials. Additionally, advancements in targeted therapies and immunotherapies offer new hope for patients with intermediate-stage HCC. Targeted drugs such as sorafenib and lenvatinib, and immune checkpoint inhibitors such as pembrolizumab and camrelizumab have shown good efficacy in prolonging patient survival. Combined treatment strategies, including the combination of targeted drugs and immunotherapy, as well as the combination of local and systemic treatments, have become research hotspots and have achieved positive results in several clinical trials. In the future, with the development of biomarkers and multi-omics molecular typing technologies, staging and treatment of intermediate-stage HCC will become more precise and personalized. The multidisciplinary team (MDT) approach helps integrate expertise from different disciplines to provide comprehensive and precise diagnostic and therapeutic plans for patients, improve treatment outcomes, and extend patient survival.

The American Joint Committee on Cancer and the International Union for Cancer Control update the tumor-node-metastasis (TNM) cancer staging system periodically. The most recent revision is the 7th edition, effective for cancers diagnosed on or after January 1, 2010. This editorial summarizes the background of the current revision and outlines the major issues revised. Most notable are the marked increase in the use of international datasets for more highly evidenced-based changes in staging, and the enhanced use of nonanatomic prognostic factors in defining the stage grouping. The future of cancer staging lies in the use of enhanced registry data standards to support personalization of cancer care through cancer outcome prediction models and nomograms.

The Cancer of the Liver Italian Program (CLIP) investigators. A new prognostic system for hepatocellular carcinoma: a retrospective study of 435 patients: the Cancer of the Liver Italian Program (CLIP) investigators[J]. Hepatology, 1998, 28(3):751-755.DOI:10.1002/hep.510280322.
The clinical outcome of cirrhotic patients with hepatocellular carcinoma (HCC) depends both on the residual liver function and tumor characteristics. However, the relative prognostic weight of these variables is not well defined. The aims of this study were to verify the value of known prognostic factors and to devise a prognostic index more sensitive than the commonly used Okuda stage. A retrospective analysis of the cases of HCC diagnosed at 16 Italian institutions from 1990 to 1992 was performed. Overall survival was the only end point used in the analysis. The Cox model, stratified by locoregional treatment, was used for multivariate analyses. The final model was derived from 10 randomly chosen training samples, and the prognostic validity of the Cancer of the Liver Italian Program (CLIP) score was assessed on the corresponding testing samples. Four hundred thirty-five cases of HCC were collected. As of January 1997, 313 patients (72%) were deceased. Overall median survival was 20 months. At multivariate analysis, independent predictive factors of survival were Child-Pugh stage, tumor morphology, alpha-fetoprotein (AFP), and portal vein thrombosis. A simple scoring system (CLIP score) was thus produced, assigning linear scores (0/1/2) to the covariates. Compared with Okuda stage, the CLIP score, structured as a six-category tool, has a greater discriminant ability, revealing a class of patients with an impressively more favorable prognosis and another class with a relatively shorter life expectancy. The CLIP score is a new prognostic system that accounts for both liver function and tumor characteristics. It is easy to calculate and appears to give more precise information than the Okuda stage.

In patients with hepatocellular carcinoma, prediction of survival is difficult. The aim of this prospective study was to provide a simple classification for predicting survival of patients with hepatocellular carcinoma, based on a multivariable Cox model.Seven hundred and sixty-one patients who presented with hepatocellular carcinoma from 24 Western medical centers were enrolled over a 30-month period. Patients were randomly assigned to either a training sample (n=506, with 418 deaths) from which a classification system was established, or a test sample (n=255, with 200 deaths) for validating its prognostic significance.Five prognostic factors were selected at the 0.0001 level: Karnofsky index <80% (relative risk of death=2.2, 95% confidence interval: 1.7-2.7), serum bilirubin >50 micromol/l (relative risk=2.1, 95% confidence interval: 1.7-2.6), serum alkaline phosphatase at least twice the upper limit of normal range (relative risk=1.6, 95% confidence interval: 1.3-2.0), serum alpha-fetoprotein >35 microg/l (relative risk=1.7, 95% confidence interval: 1.4-2.1), and ultrasonographic portal obstruction (relative risk=1.3, 95% confidence interval: 1.1-1.7). Three risk groups with different 1-year survival rates (72%, 34%, 7%) were derived, and independently validated in the test sample (79%, 31%, 4%).This classification could be useful in the assessment of prognosis from homogeneous groups of patients with respect to their expected outcome.

The classifications of hepatocellular carcinoma (HCC) currently used are based on prognostic factors obtained from studies performed years ago when most tumors were diagnosed at advanced stages and the survival rates were substantially poor. Recent investigations have reviewed the survival of early tumors properly selected to receive radical therapies and the natural outcome of nonsurgical HCC patients. These data enable a new staging system to be proposed, the Barcelona Clinic Liver Cancer (BCLC) staging classification, that comprises four stages that select the best candidates for the best therapies currently available. Early stage (A) includes patients with asymptomatic early tumors suitable for radical therapies--resection, transplantation or percutaneous treatments. Intermediate stage (B) comprises patients with asymptomatic multinodular HCC. Advanced stage (C) includes patients with symptomatic tumors and/or an invasive tumoral pattern (vascular invasion/extrahepatic spread). Stage B and C patients may receive palliative treatments/new agents in the setting of phase II investigations or randomized controlled trials. End-stage disease (D) contain patients with extremely grim prognosis (Okuda stage III or PST 3-4) that should merely receive symptomatic treatment.

The current TNM staging system for patients with hepatocellular carcinoma (HCC) does not include liver function parameters and does not provide a precise prognosis for patients in different risk groups. The objectives of this study were to construct a new prognostic index for patients with hepatocellular carcinoma, the Chinese University Prognostic Index (CUPI), and to compare it with existing staging systems in terms of their ability to classify patients into different risk group.From 1996 to 1998, 926 ethnic Chinese patients who were diagnosed with HCC (mainly hepatitis B-associated) at a single institution were recruited prospectively into this study. A multivariate analysis on 19 patient characteristics was performed using a Cox regression model to identify independent prognostic factors. Weights were derived from the regression coefficients of various factors to construct the CUPI. Patients were classified according to different staging systems. Survival curves were plotted with the Kaplan-Meier method and were compared by using a log-rank test.Both the TNM staging system and the Okuda staging system had prognostic significance, but the significance was lower for the Cancer of the Liver Italian Program (CLIP) prognostic score among the patients in the study population. The CUPI was constructed by adding the following factors into the TNM staging system: total bilirubin, ascites, alkaline phosphatase, alpha fetoprotein, and asymptomatic disease on presentation. The new CUPI characterized three risk groups with highly significant differences in survival during the whole period of follow-up (P < 0.00001) and was more discriminant than the other systems.In the study population of patients with mainly hepatitis B-associated HCC, the CUPI was more discriminant than the TNM staging system, the Okuda staging systems, or the CLIP prognostic score in classifying patients into different risk groups and was better at predicting survival. The CUPI needs to be validated by different cohorts of patients before it can be recommended for general use.Copyright 2002 American Cancer Society.

There is great geographical variation in the distribution of hepatocellular carcinoma (HCC), with the majority of all cases worldwide found in the Asia-Pacific region, where HCC is one of the leading public health problems. Since the "Toward Revision of the Asian Pacific Association for the Study of the Liver (APASL) HCC Guidelines" meeting held at the 25th annual conference of the APASL in Tokyo, the newest guidelines for the treatment of HCC published by the APASL has been discussed. This latest guidelines recommend evidence-based management of HCC and are considered suitable for universal use in the Asia-Pacific region, which has a diversity of medical environments.

A clinical staging system for cancer patients provides guidance for patient assessment and making therapeutic decisions. It is useful in deciding whether to treat a patient aggressively, and in avoiding the overtreatment of patients who would not tolerate the treatment or patients whose life expectancy rules out any chance of treatment. Clinical staging is also an essential tool for comparison between groups in therapeutic trials and for comparison between different studies. The current classifications most commonly used for hepatocellular carcinoma (HCC) are the Okuda stages, the Child-Pugh staging system, tumor node metastasis (TNM) staging, and the Cancer of the Liver Italian Program (CLIP) score. Among these, the CLIP score is currently the most commonly used integrated staging score, including both tumor stage and liver disease stage. Although the CLIP score has been well validated by many authors in terms of its prognostic value in HCC patients, this score has some problems and limitations when applied to currently diagnosed HCC patients, who are diagnosed in the early stage of disease. First, the CLIP score can discriminate score 0- to 3-patient populations, but it is not able to discriminate score 4- to 6-patient groups. Second, the definition of tumor morphology in the best prognostic group is too advanced, i.e., uninodular and a tumor extent of less than 50% of the liver. As a result, the prognosis of the CLIP system best prognostic group is not so good. In other words, this system cannot identify the best prognostic group who would benefit from curative and aggressive treatment. Third, nearly 80% of the patient population is classified as having a CLIP score of 0-2, as confirmed by many studies, which shows poor stratification ability. In contrast, a new staging system based on the Liver Cancer Study Group of Japan (LCSGJ), the Japan Integrated Staging (JIS) score is currently proposed in Japan. This staging system combines Child-Pugh grade (grade A, score 0; grade B, score 1; grade C, score 2) and TNM staging by the LCSGJ criteria (stage I, score 0; stage II, score 1; stage III, score 2; stage IV, score 3). The stratification ability of the JIS scoring system is much better than that of the CLIP scoring system. The JIS scoring system also performed better than the CLIP scoring system in selecting the best prognostic patient group. The cumulative 10-year survival rates of the best prognostic groups in the CLIP staging system (CLIP score 0) and JIS staging system (JIS score 0) were 23% and 65%, respectively (P < 0.01). All scoring systems arise as a compromise between simplicity and discriminatory ability. We confirmed that the JIS score increases predictive efficacy, while remaining simple compared with the CLIP score. Because the JIS score is quite easily obtained and is objective, we strongly propose it for widespread use as a prognostic staging system for HCC in clinical practice.

The 5th version of the Clinical Practice Guidelines for Hepatocellular Carcinoma was revised by the Japan Society of Hepatology, according to the methodology of evidence-based medicine and partly to the Grading of Recommendations Assessment, Development and Evaluation system, which was published in October 2021 in Japanese. In addition to surveillance-diagnostic and treatment algorithms, a new algorithm for systemic therapy has been created, as multiple drugs for hepatocellular carcinoma can be currently selected. Herein, new or revised algorithms and evidence on which the recommendations are based are described. This article is protected by copyright.

Survival of patients with hepatocellular carcinoma (HCC) is determined by the extent of the tumor and the underlying liver function. We aimed to develop a survival model for HCC based on objective parameters including the Model for Endstage Liver Disease (MELD) as a gauge of liver dysfunction. This analysis is based on 477 patients with HCC seen at Mayo Clinic Rochester between 1994 and 2008 (derivation cohort) and 904 patients at the Korean National Cancer Center between 2000 and 2003 (validation cohort). Multivariate proportional hazards models and corresponding risk score were created based on baseline demographic, clinical, and tumor characteristics. Internal and external validation of the model was performed. Discrimination and calibration of this new model were compared against existing models including Barcelona Clinic Liver Cancer (BCLC), Cancer of the Liver Italian Program (CLIP), and Japan Integrated Staging (JIS) scores. The majority of the patients had viral hepatitis as the underlying liver disease (100% in the derivation cohort and 85% in the validation cohort). The survival model incorporated MELD, age, number of tumor nodules, size of the largest nodule, vascular invasion, metastasis, serum albumin, and alpha-fetoprotein. In cross-validation, the coefficients remained largely unchanged between iterations. Observed survival in the validation cohort matched closely with what was predicted by the model. The concordance (c)-statistic for this model (0.77) was superior to that for BCLC (0.71), CLIP (0.70), or JIS (0.70). The score was able to further classify patient survival within each stage of the BCLC classification.A new model to predict survival of HCC patients based on objective parameters provides refined prognostication and supplements the BCLC classification.Copyright © 2012 American Association for the Study of Liver Diseases.

Surgical resection remains the gold standard for hepatocellular carcinoma (HCC). Although various staging systems have been developed in recent years, the best tool for staging of HCC remains controversial. The aims of this study were to establish a new staging for patients with HCC undergoing surgical resection and to identify whether this staging is superior to other staging systems in predicting survival of resectable HCC.The subjects of this retrospective study were 958 consecutive HCC patients who underwent surgical resection between 2000 and 2006. Predictors of survival were identified using the Kaplan-Meier method and the Cox model. The disease state was staged by our proposed Eastern staging system by integrating independent risk predictors, as well as six existing staging systems. The accuracy of prediction of 1-, 3-, and 5-year mortality for each system was evaluated by the area under the receiver operating characteristic curve (AUC).Macroscopic vascular invasion, multiple tumors, performance status 1-2, microscopic vascular invasion, extrahepatic spread, tumor size > 5 cm, albumin < 35 g/L, aspartate aminotransferase > 40 U/L, total bilirubin > 17 μmol/L, and presence of cirrhosis were identified as independent risk factors of survival after resection by multivariate analysis. The comparison of the results of the different staging systems showed that our Eastern staging had the best homogeneity (likelihood ratio χ(2) test 543.51, P < 0.001), monotonicity of gradients (linear trend χ(2) test 414.97, P < 0.001), and discriminatory ability (the highest AUCs for 1-, 3-, and 5-year mortality).Compared with other existing staging systems, our proposed Eastern staging system shows a superior predictive ability in a Chinese cohort of patients with resectable HCC, and it can give important prognostic information after surgery.

We aimed to develop a prognostic classification scheme with treatment guidance for Asian patients with hepatocellular carcinoma (HCC).We collected data from 3856 patients with HCC predominantly related to hepatitis B treated at Queen Mary Hospital in Hong Kong from January 1995 through December 2008. Data on patient performance status, Child-Pugh grade, tumor status (size, number of nodules, and presence of intrahepatic vascular invasion), and presence of extrahepatic vascular invasion or metastasis were included, and randomly separated into training and test sets for analysis. Cox regression and classification and regression tree analyses were used to account for the relative effects of factors in predicting overall survival times and to classify disparate treatment decision rules, respectively; the staging system and treatment recommendation then were constructed by integration of clinical judgments. The Hong Kong Liver Cancer (HKLC) classification was compared with the Barcelona Clinic Liver Cancer (BCLC) classification in terms of discriminatory ability and effectiveness of treatment recommendation.The HKLC system had significantly better ability than the BCLC system to distinguish between patients with specific overall survival times (area under the receiver operating characteristic curve values, approximately 0.84 vs 0.80; concordance index, 0.74 vs 0.70). More importantly, HKLC identified subsets of BCLC intermediate- and advanced-stage patients for more aggressive treatments than what were recommended by the BCLC system, which improved survival outcomes. Of BCLC-B patients classified as HKLC-II in our system, the survival benefit of radical therapies, compared with transarterial chemoembolization, was substantial (5-year survival probability, 52.1% vs 18.7%; P <.0001). In BCLC-C patients classified as HKLC-II, the survival benefit of radical therapies compared with systemic therapy was even more pronounced (5-year survival probability, 48.6% vs 0.0%; P <.0001).We collected data from patients with HCC in Hong Kong to create a system to identify patients who are suitable for more aggressive treatment than the currently used BCLC system. The HKLC system should be validated in non-Asian patient populations and in patients with different etiologies of HCC.Copyright © 2014 AGA Institute. Published by Elsevier Inc. All rights reserved.

Hepatocellular carcinoma appears frequently in patients with cirrhosis. Surveillance by biannual ultrasound is recommended for such patients because it allows diagnosis at an early stage, when effective therapies are feasible. The best candidates for resection are patients with a solitary tumour and preserved liver function. Liver transplantation benefits patients who are not good candidates for surgical resection, and the best candidates are those within Milan criteria (solitary tumour ≤5 cm or up to three nodules ≤3 cm). Image-guided ablation is the most frequently used therapeutic strategy, but its efficacy is limited by the size of the tumour and its localisation. Chemoembolisation has survival benefit in asymptomatic patients with multifocal disease without vascular invasion or extrahepatic spread. Finally, sorafenib, lenvatinib, which is non-inferior to sorafenib, and regorafenib increase survival and are the standard treatments in advanced hepatocellular carcinoma. This Seminar summarises the scientific evidence that supports the current recommendations for clinical practice, and discusses the areas in which more research is needed.Copyright © 2018 Elsevier Ltd.

The intermediate stage of hepatocellular carcinoma (HCC) comprises a highly heterogeneous patient population and therefore poses unique challenges for therapeutic management, different from the early and advanced stages. Patients classified as having intermediate HCC by the Barcelona Clinic Liver Cancer (BCLC) staging system present with varying tumor burden and liver function. Transarterial chemoembolization (TACE) is currently recommended as the standard of care in this setting, but there is considerable variation in the clinical benefit patients derive from this treatment.In April 2012, a panel of experts convened to discuss unresolved issues surrounding the application of current guidelines when managing patients with intermediate HCC. The meeting explored the applicability of a subclassification system for intermediate HCC patients to tailor therapeutic interventions based on the evidence available to date and expert opinion. The present report summarizes the proposal of the expert panel: four substages of intermediate HCC patients, B1 to B4.Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

To find a subgroup that benefits most from transarterial chemoembolization (TACE) in terms of tumor number and size and liver profile in patients with intermediate-stage hepatocellular carcinoma (HCC).Data of 325 intermediate-stage HCC patients who received TACE as the initial treatment were gathered. Four tumor numbers (3-6 tumors) and five maximum tumor diameters (3-7 cm) as well as all of their combinations but one (3 tumors and 3 cm) and Child-Pugh grade were used as variables to ascertain prognostic factors.The respective 1-, 3-, and 5-year overall survival rates in all patients were 86.5, 47.0, and 23.7%, respectively. Tumor numbers of 4 (P = 0.00145) and 5 (P = 0.036), and tumor size of 7 cm (P = 0.015), and 12 other combinations of tumor number and size, and Child-Pugh grade (P = 0.0015) were identified as significant prognostic factors in univariate analysis, and 4 tumors of 7 cm (P = 0.0008) and Child-Pugh grade (P = 0.0036) remained significant in the stepwise Cox proportional hazard model. The overall survival was significantly better in a patient subgroup having two factors other than patient subgroups having one or no prognostic factors.A patient subgroup having two prognostic factors benefited most from TACE in intermediate-stage HCC patients.

The need for a subclassification of Barcelona Clinic Liver Cancer (BCLC) intermediate-stage (BCLC B) has arisen because of its diversity. We evaluated the prognostic capability of the BCLC B subclassification proposed by Bolondi et al. in patients treated with transarterial chemoembolization (TACE). Furthermore, we introduce a new subclassification for intermediate-stage hepatocellular carcinoma (HCC) by using a new parameter related to tumour burden (up-to-11 criteria).Of 3268 patients treated with TACE as first-line treatment, 821 patients with intermediate-stage HCC were included in this study.According to the Bolondi subclassification, 208 (25.3%), 529 (64.5%), 43 (5.2%) and 41 (5%) patients were in B1, B2, B3 and B4 respectively. The B1, B2 and B3 subclasses in the Bolondi system showed significantly different survival between contiguous stages with median survival of 51.5, 26 and 14.8 months, respectively (both P<.001 for B1 vs B2 and B2 vs B3); however, survival was rather worse in B3 than B4 (14.8 vs 25 months, P=.025). According to the newly proposed subclassification, 410 (50%), 364 (44.3%) and 47 (5.7%) patients were in B1, B2 and B3 respectively. The median survival progressively decreased from B1 (44.8 months) to B2 (21.5 months) and B3 (11.3 months), with a significant difference between contiguous stages (both P<.001 for B1 vs B2 and B2 vs B3).Our new BCLC B substaging system, with up-to-11 criteria and Child-Pugh class as main parameters, has excellent discriminatory power to subclassify TACE-treated patients into three prognostic substages.© 2017 John Wiley & Sons A/S.

Intermediate-stage [Barcelona Clinic Liver Cancer stage-B (BCLC-B)] hepatocellular carcinoma (HCC) comprises of a heterogeneous population of patients with a wide range of tumor burdens. We therefore formulated a subclassification of BCLC-B HCC using the up-to-seven criteria and tumor markers according to the results of a retrospective analysis of these patients.This study included 125 patients newly diagnosed with BCLC-B HCC who underwent transarterial chemoembolization. Among them, 39 and 86 were within or beyond the up-to-seven criteria, respectively. Multivariate Cox proportional hazards analysis was performed to investigate factors that contributed to better prognosis associated with the criteria.Cumulative overall survival (OS) and disease-free survival rates were significantly higher for patients within the up-to-seven criteria compared with those beyond (p = 0.034 and p = 0.001, respectively). Multivariate analysis revealed that low concentrations of des-γ-carboxy prothrombin (DCP) (<150 mAU/ml) and α-fetoprotein (AFP) (<100 ng/ml) were independent contributors to better OS of patients within or beyond the up-to-seven criteria, respectively. Accordingly, the patients were classified as follows: group A (patients within the up-to-seven criteria with DCP <150 mAU/ml), group C (patients beyond the up-to-seven criteria with AFP ≥100 ng/ml), and group B (other patients). OS differed significantly among groups (p < 0.001), and the median survival times of group A, B, and C were 4.2, 2.7, and 1.5 years, respectively.The subclassification system incorporating the up-to-seven criteria combined with DCP and AFP levels may serve as better predictors of prognosis that may guide efforts to improve treatment strategies.

Intermediate-stage hepatocellular carcinoma (BCLC B HCC) occurs in a heterogeneous group of patients and can be addressed with a wide spectrum of treatments. Consequently, survival significantly varies among patients. In recent years, several subclassification systems have been proposed to stratify patients' prognosis. We analyzed and compared these systems (Bolondi, Yamakado, Kinki, Wang, Lee, and Kim criteria) in patients undergoing systemic therapy.We considered 171 patients with BCLC B HCC treated with sorafenib as first-line systemic therapy in six Italian centers from 2010 to 2021 and retrospectively applied the criteria of six different subclassification systems.Except for the Yamakado criteria, all the subclassification systems showed a statistically significant correlation to overall survival (OS). In the postestimation analysis, the Bolondi criteria (OS of subgroups 22.5, 11.9, and 6.6 mo, respectively; C-index 0.586; AIC 1338; BIC 1344) and the Wang criteria (OS of subgroups 20.6, 11.9, and 7.0, respectively; C-index 0.607; AIC 1337; BIC 1344) presented the best accuracy. Further analyses of these two subclassification systems implemented with the prognostic factor of alpha-fetoprotein (AFP) > 400 ng/mL have shown an increase in accuracy for both systems (C-index 0.599 and 0.624, respectively).Intermediate-stage subclassification systems maintain their predictive value also in the setting of systemic therapy. The Bolondi and Wang criteria showed the highest accuracy. AFP > 400 ng/mL enhances the performance of these systems.

Previous prognostic scores for transarterial chemoembolization (TACE) were mainly derived from real-world settings, which are beyond guideline recommendations. A robust model for outcome prediction and risk stratification of recommended TACE candidates is lacking. We aimed to develop an easy-to-use tool specifically for these patients.Between January 2010 and May 2016, 1,604 treatment-naïve patients with unresectable hepatocellular carcinoma (HCC), Child-Pugh A5-B7 and performance status 0 undergoing TACE were included from 24 tertiary centres. Patients were randomly divided into training (n = 807) and validation (n = 797) cohorts. A prognostic model was developed and subsequently validated. Predictive performance and discrimination were further evaluated and compared with other prognostic models.The final presentation of the model was "linear predictor = largest tumour diameter (cm) + tumour number", which consistently outperformed other currently available models in both training and validation datasets as well as in different subgroups. The thirtieth percentile and the third quartile of the linear predictor, namely 6 and 12, were further selected as cut-off values, leading to the "six-and-twelve" score which could divide patients into 3 strata with the sum of tumour size and number ≤6, >6 but ≤12, and >12 presenting significantly different median survival of 49.1 (95% CI 43.7-59.4) months, 32.0 (95% CI 29.9-37.5) months, and 15.8 (95% CI 14.1-17.7) months, respectively.The six-and-twelve score may prove an easy-to-use tool to stratify recommended TACE candidates (Barcelona Clinic Liver Cancer stage-A/B) and predict individual survival with favourable performance and discrimination. Moreover, the score could stratify these patients in clinical practice as well as help design clinical trials with comparable criteria involving these patients. Further external validation of the score is required.There is currently no prognostic model specifically developed for recommended or ideal transarterial chemoembolization (TACE) candidates with hepatocellular carcinoma, despite these patients being frequently identified as the best target population in pivotal randomized controlled trials. The six-and-twelve score provides patient survival prediction, especially in ideal candidates of TACE, outperforming other currently available models in both training and validation sets, as well as different subgroups. With cut-off values of 6 and 12, the score can stratify ideal TACE candidates into 3 strata with significantly different outcomes and may shed light on risk stratification of these patients in clinical practice as well as in clinical trials.Copyright © 2019 European Association for the Study of the Liver.

<b><i>Background and Aims:</i></b> For patients with intermediate-stage hepatocellular carcinoma (HCC), the definition of high tumor burden remains controversial. This study aimed to compare the prognostic value of different criteria of tumor burden in patients with intermediate-stage HCC undergoing transarterial chemoembolization (TACE). <b><i>Methods:</i></b> From 2007 to 2019, 632 treatment-naive patients with intermediate-stage HCC undergoing TACE were retrospectively enrolled. We compared different criteria of tumor burden in discriminating radiologic response and survival, including up-to-7, up-to-11, 5–7, 7 lesions criteria, and newly proposed 7–11 criteria. <b><i>Results:</i></b> The proportions of patients classified as high tumor burden were varied by different criteria. Among the 5 criteria, 7–11 criteria have the best performance to discriminate complete response (CR) and overall survival (OS) after TACE. In patients with low, intermediate, and high tumor burden classified by 7–11 criteria, the CR rate was 21, 12, and 2.5%, respectively (<i>p</i> &#x3c; 0.001), and the median OS was 33.1, 22.3, and 11.9 months, respectively (<i>p</i> &#x3c; 0.001). By multivariate analysis, 7–11 criteria were significantly associated with CR (intermediate vs. high burden, odds ratio = 4.617, <i>p</i> = 0.002; low vs. high burden, odds ratio = 8.675, <i>p</i> &#x3c; 0.001) and OS (intermediate vs. high burden, hazard ratio = 0.650, <i>p</i> &#x3c; 0.001; low vs. high burden, hazard ratio = 0.520, <i>p</i> &#x3c; 0.001). Seven to 11 criteria also had the lowest corrected Akaike information criteria, highest homogeneity value, and highest area under the receiver operating characteristic curve in predicting 1-, 2-, and 3-year mortality among all criteria. <b><i>Conclusion:</i></b> Conventional definitions of tumor burden were not optimal for patients with intermediate HCC. The new 7–11 criteria had the best discriminative power in predicting radiologic response and survival in patients with intermediate-stage HCC undergoing TACE.

To develop radiomics-based nomograms for preoperative microvascular invasion (MVI) and recurrence-free survival (RFS) prediction in patients with solitary hepatocellular carcinoma (HCC) ≤ 5 cm.

Radiomics has emerged as a new approach that can help identify imaging information associated with tumor pathophysiology. We developed and validated a radiomics nomogram for preoperative prediction of microvascular invasion (MVI) in hepatocellular carcinoma (HCC).Two hundred and eight patients with pathologically confirmed HCC (training cohort: = 146; validation cohort: = 62) who underwent preoperative gadoxetic acid-enhanced magnetic resonance (MR) imaging were included. Least absolute shrinkage and selection operator logistic regression was applied to select features and construct signatures derived from MR images. Univariate and multivariate analyses were used to identify the significant clinicoradiological variables and radiomics signatures associated with MVI, which were then incorporated into the predictive nomogram. The performance of the radiomics nomogram was evaluated by its calibration, discrimination, and clinical utility.Higher α-fetoprotein level ( = 0.046), nonsmooth tumor margin ( = 0.003), arterial peritumoral enhancement ( 0.001), and the radiomics signatures of hepatobiliary phase (HBP) T1-weighted images ( 0.001) and HBP T1 maps ( 0.001) were independent risk factors of MVI. The predictive model that incorporated the clinicoradiological factors and the radiomic features derived from HBP images outperformed the combination of clinicoradiological factors in the training cohort (area under the curves [AUCs] 0.943 vs. 0.850; = 0.002), though the validation did not have a statistical significance (AUCs 0.861 vs. 0.759; = 0.111). The nomogram based on the model exhibited C-index of 0.936 (95% CI 0.895-0.976) and 0.864 (95% CI 0.761-0.967) in the training and validation cohort, fitting well in calibration curves (> 0.05). Decision curve analysis further confirmed the clinical usefulness of the nomogram.The nomogram incorporating clinicoradiological risk factors and radiomic features derived from HBP images achieved satisfactory preoperative prediction of the individualized risk of MVI in patients with HCC.Copyright © 2018 by S.

In the 2010 version of the Japan Society of Hepatology (JSH) consensus-based treatment algorithm for the management of hepatocellular carcinoma (HCC), transarterial chemoembolization (TACE) failure/refractoriness was defined assuming the use of superselective lipiodol TACE, which has been widely used worldwide and particularly in Japan, and areas with lipiodol deposition were considered to be necrotic. However, this concept is not well accepted internationally. Furthermore, following the approval of microspheres, an embolic material that does not use lipiodol, in February 2014 in Japan, the phrase ‘lipiodol deposition' needed to be changed to ‘necrotic lesion or viable lesion'. Accordingly, the respective section in the JSH guidelines was revised to define TACE failure as an insufficient response after ≥2 consecutive TACE procedures that is evident on response evaluation computed tomography or magnetic resonance imaging after 1-3 months, even after chemotherapeutic agents have been changed and/or the feeding artery has been reanalyzed. In addition, the appearance of a higher number of lesions in the liver than that recorded at the previous TACE procedure (other than the nodule being treated) was added to the definition of TACE failure/refractoriness. Following the discussion of other issues concerning the continuous elevation of tumor markers, vascular invasion, and extrahepatic spread, descriptions similar to those in the previous version were approved. The revision of these TACE failure definitions was approved by over 85% of HCC experts. © 2014 S. Karger AG, Basel

Patients with unresectable hepatocellular carcinoma (HCC) usually receive transarterial chemoembolization (TACE) or systemic therapies with intermediate and advanced-stage disease. However, intermediate-stage HCC patients often have unsatisfactory clinical outcomes with repeated TACE and there is considerable uncertainty surrounding the criteria for repeating or stopping TACE treatment. In July 2012, an Expert Panel Opinion on Interventions in Hepatocellular Carcinoma (EPOIHCC) was re-convened in Shanghai in an attempt to provide a consensus on the practice of TACE, particularly in regard to evaluating TACE 'failure'. To that end, current clinical practice throughout Asia was reviewed in detail including safety and efficacy data on TACE alone as well as in combination with targeted systemic therapies for intermediate HCC. This review summarizes the evidence discussed at the meeting and provides expert recommendations regarding the use of TACE for unresectable intermediate-stage HCC. A key consensus of the Expert Panel was that the current definitions of TACE failure are not useful in differentiating between situations where TACE is no longer effective in controlling disease locally vs. systemically. By redefining these concepts, it may be possible to provide a clearer indication of when TACE should be repeated and more importantly, when TACE should be discontinued. © 2013 John Wiley & Sons A/S.

Hepatocellular carcinoma (HCC)-closely associated with liver cirrhosis and, in fact, the main cause of death in patients with such disease-is now recognized as one of the most-prevalent and lethal neoplasms worldwide. Prognosis and allocation of the multiple available treatment options for patients with HCC are influenced not only by tumour stage, but also by the degree of liver-function impairment. Therefore, accurate assessment and classification of disease is important for patient management. According to the Barcelona Clinic Liver Cancer (BCLC) algorithm, intermediate-stage HCC is defined as extensive multifocal disease without vascular invasion in patients with preserved liver function and absence of cancer-related symptoms; in this context, transarterial chemoembolization (TACE) is considered the standard treatment. The use of drug-eluting beads has enabled standardization of this procedure, resulting in higher reproducibility and tolerability of the treatment. Nevertheless, not all patients with intermediate-stage HCC are good candidates for TACE and, for such patients in whom TACE is not appropriate or has failed, other treatments can be considered, including sorafenib. Radioembolization is a promising alternative that deserves further prospective studies. Herein, we review the current approaches used to accurately stratify patients with intermediate-stage HCC and subsequently allocate the most-appropriate treatments. The key developments in therapeutic strategies are also discussed.

Although transarterial chemoembolization is recommended as the standard treatment for Barcelona Clinic Liver Cancer stage B hepatocellular carcinoma (BCLC-B HCC), other treatments including liver resection have been used. This study aimed to determine the survival benefit of treatment strategies including resection for BCLC-B HCC compared with non-surgical treatments.The nationwide multicentre database of the Korean Liver Cancer Association was reviewed. Patients with BCLC-B HCC who underwent liver resection as a first or second treatment within 2 years of diagnosis and patients who received non-surgical treatment were selected randomly. Survival outcomes of propensity score-matched groups were compared.Among 887 randomly selected patients with BCLC-B HCC, 83 underwent liver resection as first or second treatment and 597 had non-surgical treatment. After propensity score matching, the two groups were well balanced (80 patients in each group). Overall median survival in the resection group was better than that for patients receiving non-surgical treatment (50·9 versus 22·1 months respectively; P < 0·001). The 1-, 2-, 3- and 5-year overall survival rates in the resection group were 90, 88, 75 and 63 per cent, compared with 79, 48, 35 and 22 per cent in the no-surgery group (P < 0·001). In multivariable analysis, non-surgical treatment only (hazard ratio (HR) 3·35, 95 per cent c.i. 2·16 to 5·19; P < 0·001), albumin level below 3·5 g/dl (HR 1·96, 1·22 to 3·15; P = 0·005) and largest tumour size greater than 5·0 cm (HR 1·81, 1·20 to 2·75; P = 0·005) were independent predictors of worse overall survival.Treatment strategies that include liver resection offer a survival benefit compared with non-surgical treatments for potentially resectable BCLC-B HCC.© 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

Compared to transarterial chemoembolization (TACE) for patients with hepatocellular carcinoma (HCC), stage B in the Barcelona Clinic Liver Cancer (BCLC) classification, the role of hepatic resection remains unclear. The present study compared the long‐term outcome of hepatic resection with TACE in the treatment of BCLC stage B HCC.

The role of hepatic resection for hepatocellular carcinoma (HCC) in different Barcelona Clinic Liver Cancer (BCLC) stages is controversial. We aimed at measuring the survival benefit of resection vs. non-surgical-therapies in each BCLC stage.Using the ITA.LI.CA database, we identified 2090 BCLC A, B, and C HCC patients observed between 2000 and 2012: 550 underwent resection, 1046 loco-regional therapy (LRT), and 494 best supportive care (BSC). A multivariate log-logistic model was chosen to predict median survival (MS) after resection vs. MS after LRT or BSC. The results were expressed as net survival benefit of resection: (MS resection-MS LRT)/MS BSC.After stratifying for BCLC stage, the median net survival benefit of resection over LRT was: BCLC 0=62% (40%, 82%), A=45% (13%, 65%), B=46% (9%, 76%), C=-16% (-55%, 33%). Model for end-stage liver disease (MELD) score>9, Child B class, and performance status (PST)=2 were the main risk factors for liver resection. 1181 Child A patients (57%) with MELD⩽9 and PST<2 had always a large positive net survival benefit of resection over LRT, independently of BCLC stage: BCLC 0=64% (44%, 85%), A=59% (45%, 74%), B=71% (52%, 90%), C=56% (36%, 78%). Among the 909 (43%) patients with at least one risk factor (MELD>9 or PST=2 or Child B class), resection did not prove any survival benefit over LRT.Resection could result in survival benefit over LRT for HCC patients regardless of their BCLC stage, provided that liver dysfunction (Child B or MELD>9) and PST>1 are absent.Copyright © 2014 European Association for the Study of the Liver.

High rate of tumor recurrence jeopardized the long-term survival of hepatocellular carcinoma (HCC) patients with complete response to transarterial chemoembolization (TACE). This study aims to evaluate the survival benefit of liver resection (LR) following the complete response to TACE for intermediate-stage HCC.A total of 281 intermediate-stage HCC patients with complete response to TACE followed by persistent observation (TACE group) or LR (TLR group) from 01 January 2011 to 31 December 2021 from three institutions in China were included. Overall survival (OS) and disease-free survival (DFS) of patients were compared between the two groups by propensity score-matching (PSM).After PSM, the 1-year, 3-year, and 5-year OS rates were 91.4, 71.5, and 57.1% in the TACE group, and 96.6, 81.8, and 72.1% in the TLR group. The 1-year, 3-year, and 5-year DFS rates were 50.6, 22.6, and 6.8% in the TACE group, and 77.3, 56.3, and 38.7% in the TLR group. Compared with the TACE group, the TLR group showed significantly longer OS (HR, 0.528; 95% CI: 0.315-0.887; P =0.014) and DFS (HR, 0.388; 95% CI: 0.260-0.580; P <0.001). In patients beyond up-to-seven criterion, no difference was observed with OS (HR, 0.708; 95% CI: 0.354-1.419; P =0.329). LR following the complete response to TACE was safety.This study suggests that intermediate-stage HCC patients could benefit from LR following the complete response to TACE, resulting in longer OS and DFS. In addition, patients beyond up-to-seven could not benefit from the LR treatments.Copyright © 2023 The Author(s). Published by Wolters Kluwer Health, Inc.

It is unclear which patients benefit from resection in intermediate-stage-hepatocellular carcinoma (HCC). The authors aimed to identify high-risk patients for early recurrence among patients with resectable intermediate-stage HCC.This multicenter retrospective study included patients who underwent resection or trans-arterial chemoembolization (TACE) for intermediate-stage HCC (2008-2019). Multivariable Cox proportional analysis was performed to identify high-risk patients when treated with resection. A prediction score for 2-year recurrence-free survival (RFS) was developed using the training cohort and validated. The 2-year RFS in each risk group was compared with that in TACE group, after propensity score matching (PSM).A total of 1686 patients were included (480 and 1206 patients in the resection and TACE groups). During a median follow-up of 31.4 months, the 2-year RFS was significantly higher in the resection (47.7%) than in the TACE group (19.8%) [adjusted hazard ratio (aHR)=1.471, 95% CI: 1.199-1.803, P <0.001). On multivariate analysis, alpha-fetoprotein ≥5.0 ng/ml (aHR=0.202), ALBI grade ≥2 (aHR=0.709), tumor number ≥3 (aHR=0.404), and maximal tumor size ≥5 cm (aHR=0.323) were significantly associated with the lower risk of 2-year RFS in the resection group. The newly developed Surgery Risk score in BCLC-B (SR-B score) with four significant risk factors showed an area under the curve of 0.801 for the 2-year RFS and was validated. Based on the SR-B score, low-risk patients had a significantly higher 2-year RFS (training: aHR=5.834; validation: aHR=5.675) than high-risk patients (all P <0.001) did. In a PSM cohort, a low-risk resection group had a significantly higher (aHR=3.891); a high-risk resection group had a comparable 2-year RFS to those treated with TACE (aHR=0.816).Resection may be beneficial for resectable intermediate-stage HCC based on the SR-B score.Copyright © 2023 The Author(s).

To determine whether FOLFOX4 (infusional fluorouracil, leucovorin, and oxaliplatin) administered as palliative chemotherapy to patients with advanced hepatocellular carcinoma (HCC) provides a survival benefit and efficacy versus doxorubicin.This multicenter, open-label, randomized, phase III study in mainland China, Taiwan, Korea, and Thailand involved 371 patients age 18 to 75 years who had locally advanced or metastatic HCC and were ineligible for curative resection or local treatment. They were randomly assigned at a ratio of one to one to receive either FOLFOX4 (n = 184) or doxorubicin (n = 187). The primary end point was overall survival (OS); secondary end points included progression-free survival (PFS), response rate (RR) by RECIST (version 1.0), and safety.At the prespecified final analysis, median OS was 6.40 months with FOLFOX4 (95% CI, 5.30 to 7.03) and 4.97 months with doxorubicin (95% CI, 4.23 to 6.03; P =.07; hazard ratio [HR], 0.80; 95% CI, 0.63 to 1.02). Median PFS was 2.93 months with FOLFOX4 (95% CI, 2.43 to 3.53), and 1.77 months with doxorubicin (95% CI, 1.63 to 2.30; P <.001; HR, 0.62; 95% CI, 0.49 to 0.79). RR was 8.15% with FOLFOX4 and 2.67% with doxorubicin (P =.02). On continued follow-up, the trend toward increased OS with FOLFOX4 was maintained (P =.04; HR, 0.79; 95% CI, 0.63 to 0.99). Toxicity was consistent with previous experiences with FOLFOX4; proportions of grade 3 to 4 adverse events were similar between treatments.Although the study did not meet its primary end point, the trend toward improved OS with FOLFOX4, along with increased PFS and RR, suggests that this regimen may confer some benefit to Asian patients, but an OS benefit cannot be concluded from these data.

Sorafenib is the first-line treatment for hepatocellular carcinoma with portal vein invasion; however, it has shown unsatisfactory survival benefit. Sorafenib plus hepatic arterial infusion chemotherapy (HAIC) of oxaliplatin, fluorouracil, and leucovorin (FOLFOX) has shown promising results for these patients in a previous phase 2 study.To investigate the efficacy and safety of sorafenib plus HAIC compared with sorafenib for hepatocellular carcinoma with portal vein invasion.This randomized, open-label clinical trial enrolled 818 screened patients. Of the 818 participants, 247 with hepatocellular carcinoma and portal vein invasion were randomly assigned (1:1) via a computer-generated sequence to receive sorafenib plus HAIC or sorafenib. This trial was conducted at 5 hospitals in China and enrolled patients from April 1, 2016, to October 10, 2017, with a follow-up period of 10 months.Randomization to receive 400 mg sorafenib twice daily (sorafenib group) or 400 mg sorafenib twice daily plus HAIC (SoraHAIC group) (oxaliplatin 85 mg/m2, leucovorin 400 mg/m2, fluorouracil bolus 400 mg/m2 on day 1, and fluorouracil infusion 2400 mg/m2 for 46 hours, every 3 weeks).The primary endpoint was overall survival by intention-to-treat analysis. Safety was assessed in patients who received at least 1 dose of study treatment.For 247 patients (median age, 49 years; range, 18-75 years; 223 men and 24 women), median overall survival was 13.37 months (95% CI, 10.27-16.46) in the SoraHAIC group vs 7.13 months (95% CI, 6.28-7.98) in the sorafenib group (hazard ratio [HR], 0.35; 95% CI, 0.26-0.48; P < .001). The SoraHAIC group showed a higher response rate than the sorafenib group (51 [40.8%] vs 3 [2.46%]; P < .001), and a longer median progression-free survival (7.03 [95% CI, 6.05-8.02] vs 2.6 [95% CI, 2.15-3.05] months; P < .001). Grade 3/4 adverse events that were more frequent in the SoraHAIC group than in the sorafenib group included neutropenia (12 [9.68%] vs 3 [2.48%]), thrombocytopenia (16 [12.9%] vs 6 [4.96%]), and vomiting (8 [6.45%] vs 1 [0.83%]).Sorafenib plus HAIC of FOLFOX improved overall survival and had acceptable toxic effects compared with sorafenib in patients with hepatocellular carcinoma and portal vein invasion.ClinicalTrials.gov identifier: NCT02774187.

Purpose Selective internal radiation therapy or radioembolization (RE) shows efficacy in unresectable hepatocellular carcinoma (HCC) limited to the liver. This study compared the safety and efficacy of RE and sorafenib in patients with locally advanced HCC. Patients and Methods SIRveNIB (selective internal radiation therapy v sorafenib), an open-label, investigator-initiated, phase III trial, compared yttrium-90 (Y) resin microspheres RE with sorafenib 800 mg/d in patients with locally advanced HCC in a two-tailed study designed for superiority/detriment. Patients were randomly assigned 1:1 and stratified by center and presence of portal vein thrombosis. Primary end point was overall survival (OS). Efficacy analyses were performed in the intention-to-treat population and safety analyses in the treated population. Results A total of 360 patients were randomly assigned (RE, 182; sorafenib, 178) from 11 countries in the Asia-Pacific region. In the RE and sorafenib groups, 28.6% and 9.0%, respectively, failed to receive assigned therapy without significant cross-over to either group. Median OS was 8.8 and 10.0 months with RE and sorafenib, respectively (hazard ratio, 1.1; 95% CI, 0.9 to 1.4; P =.36). A total of 1,468 treatment-emergent adverse events (AEs) were reported (RE, 437; sorafenib, 1,031). Significantly fewer patients in the RE than sorafenib group had grade ≥ 3 AEs (36 of 130 [27.7%]) v 82 of 162 [50.6%]; P <.001). The most common grade ≥ 3 AEs were ascites (five of 130 [3.8%] v four of 162 [2.5%] patients), abdominal pain (three [2.3%] v two [1.2%] patients), anemia (zero v four [2.5%] patients), and radiation hepatitis (two [1.5%] v zero [0%] patients). Fewer patients in the RE group (27 of 130 [20.8%]) than in the sorafenib group (57 of 162 [35.2%]) had serious AEs. Conclusion In patients with locally advanced HCC, OS did not differ significantly between RE and sorafenib. The improved toxicity profile of RE may inform treatment choice in selected patients.

The Sorafenib Hepatocellular Carcinoma (HCC) Assessment Randomized Protocol (SHARP) trial demonstrated that sorafenib improves overall survival and is safe for patients with advanced HCC. In this trial, 602 patients with well-preserved liver function (>95% Child-Pugh A) were randomized to receive either sorafenib 400mg or matching placebo orally b.i.d. on a continuous basis. Because HCC is a heterogeneous disease, baseline patient characteristics may affect individual responses to treatment. In a comprehensive series of exploratory subgroup analyses, data from the SHARP trial were analyzed to discern if baseline patient characteristics influenced the efficacy and safety of sorafenib.Five subgroup domains were assessed: disease etiology, tumor burden, performance status, tumor stage, and prior therapy. Overall survival (OS), time to progression (TTP), disease control rate (DCR), and safety were assessed for subgroups within each domain.Subgroup analyses showed that sorafenib consistently improved median OS compared with placebo, as reflected by hazard ratios (HRs) of 0.50-0.85, similar to the complete cohort (HR=0.69). Sorafenib also consistently improved median TTP (HR, 0.40-0.64), except in HBV-positive patients (HR, 1.03), and DCR. Results are limited by small patient numbers in some subsets. The most common grade 3/4 adverse events included diarrhea, hand-foot skin reaction, and fatigue; the incidence of which did not differ appreciably among subgroups.These exploratory subgroup analyses showed that sorafenib consistently improved median OS and DCR compared with placebo in patients with advanced HCC, irrespective of disease etiology, baseline tumor burden, performance status, tumor stage, and prior therapy.Copyright © 2012 European Association for the Study of the Liver.

A multicenter randomized controlled trial established sorafenib as a standard of care for patients with advanced hepatocellular carcinoma (HCC). Because the study was prematurely interrupted due to survival benefits in the sorafenib arm, we conducted an observational study to adequately assess risks and benefits of this regimen in field practice. Starting in 2008, all clinically compensated patients with advanced HCC and those with an intermediate HCC who were unfit or failed to respond to ablative therapies were consecutively evaluated in six liver centers in Italy, for tolerability as well as radiologic and survival response to 800-mg/d sorafenib therapy. Treatment was down-dosed or interrupted according to drug label. Two hundred ninety-six patients (88% Child-Pugh A, 75% Barcelona Clinic Liver Cancer [BCLC]-C, and 25% BCLC-B) received sorafenib for 3.8 months (95% CI 3.3-4.4). Two hundred sixty-nine (91%) patients experienced at least one adverse event (AE), whereas 161 (54%) had to reduce dosing. Treatment was interrupted in 103 (44%) for disease progression, in 95 (40%) for an AE, and in 38 (16%) for liver deterioration. The median survival was 10.5 months in the overall cohort, 8.4 months in BCLC-C versus 20.6 months in BCLC-B patients (P < 0.0001), and 21.6 months in the 77 patients treated for >70% of the time with a half dose versus 9.6 months in the 219 patients treated for >70% of the time with a full dose. At month 2 of treatment, the overall radiologic response was 8%. Eastern Cooperative Oncology Group performance status, macrovascular invasion, extrahepatic spread of the tumor, radiologic response at month 2, and sorafenib dosing were independent predictors of shortened survival.Overall, safety, effectiveness, and generalizability of sorafenib therapy in HCC was validated in field practice. The effectiveness of half-dosed sorafenib may have implications for tailored therapy.Copyright © 2011 American Association for the Study of Liver Diseases.

Although transcatheter arterial chemoembolization (TACE) is the standard of care for intermediate-stage hepatocellular carcinoma (HCC), this is a largely heterogeneous disease that includes a subgroup of patients who do not benefit from TACE. The treatment strategy for this subgroup of patients currently remains an unmet need in clinical practice. Here, we performed a proof-of-concept study that lenvatinib may be a more favorable treatment option over TACE as an initial treatment in intermediate-stage HCC patients with large or multinodular tumours exceeding the up-to-seven criteria. This proof-of-concept study included 642 consecutive patients with HCC initially treated with lenvatinib or conventional TACE (cTACE) between January 2006 and December 2018. Of these patients, 176 who received lenvatinib or cTACE as an initial treatment and met the eligibility criteria (unresectable, beyond the up-to-seven criteria, no prior TACE/systemic therapy, no vascular invasion, no extrahepatic spread and Child–Pugh A liver function) were selected for the study. Propensity score matching was used to adjust for patient demographics. After propensity-score matching, the outcome of 30 patients prospectively treated with lenvatinib (14 in clinical trials, one in an early access program and 15 in real world settings) and 60 patients treated with cTACE as the initial treatment was compared. The change of albumin-bilirubin (ALBI) score from baseline to the end of treatment were −2.61 to −2.61 for 30 patients in the lenvatinib group (p = 0.254) and −2.66 to −2.09 in the cTACE group (p < 0.01), respectively. The lenvatinib group showed a significantly higher objective response rate (73.3% vs. 33.3%; p < 0.001) and significantly longer median progression-free survival than the cTACE group (16.0 vs. 3.0 months; p < 0.001). Overall survival was significantly longer in the lenvatinib group than in the cTACE group (37.9 vs. 21.3 months; hazard ratio: 0.48, p < 0.01). In patients with large or multinodular intermediate-stage HCC exceeding the up-to-seven criteria with Child–Pugh A liver function, who usually do not benefit from TACE, lenvatinib provides a more favorable outcome than TACE.

Single-agent nivolumab showed durable responses, manageable safety, and promising survival in patients with advanced hepatocellular carcinoma in the phase 1-2 CheckMate 040 study. We aimed to investigate nivolumab monotherapy compared with sorafenib monotherapy in the first-line setting for patients with advanced hepatocellular carcinoma.In this randomised, open-label, phase 3 trial done at medical centres across 22 countries and territories in Asia, Australasia, Europe, and North America, patients at least 18 years old with histologically confirmed advanced hepatocellular carcinoma not eligible for, or whose disease had progressed after, surgery or locoregional treatment; with no previous systemic therapy for hepatocellular carcinoma, with Child-Pugh class A and Eastern Cooperative Oncology Group performance status score of 0 or 1, and regardless of viral hepatitis status were randomly assigned (1:1) via an interactive voice response system to receive nivolumab (240 mg intravenously every 2 weeks) or sorafenib (400 mg orally twice daily) until disease progression or unacceptable toxicity. The primary endpoint was overall survival assessed in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of study drug. This completed trial is registered with ClinicalTrials.gov, NCT02576509.Between Jan 11, 2016, and May 24, 2017, 743 patients were randomly assigned to treatment (nivolumab, n=371; sorafenib, n=372). At the primary analysis, the median follow-up for overall survival was 15·2 months (IQR 5·7-28·0) for the nivolumab group and 13·4 months (5·7-25·9) in the sorafenib group. Median overall survival was 16·4 months (95% CI 13·9-18·4) with nivolumab and 14·7 months (11·9-17·2) with sorafenib (hazard ratio 0·85 [95% CI 0·72-1·02]; p=0·075; minimum follow-up 22·8 months); the protocol-defined significance level of p=0·0419 was not reached. The most common grade 3 or worse treatment-related adverse events were palmar-plantar erythrodysaesthesia (1 [<1%] of 367 patients in the nivolumab group vs 52 [14%] of patients in the sorafenib group), aspartate aminotransferase increase (22 [6%] vs 13 [4%]), and hypertension (0 vs 26 [7%]). Serious treatment-related adverse events were reported in 43 (12%) patients receiving nivolumab and 39 (11%) patients receiving sorafenib. Four deaths in the nivolumab group and one death in the sorafenib group were assessed as treatment related.First-line nivolumab treatment did not significantly improve overall survival compared with sorafenib, but clinical activity and a favourable safety profile were observed in patients with advanced hepatocellular carcinoma. Thus, nivolumab might be considered a therapeutic option for patients in whom tyrosine kinase inhibitors and antiangiogenic drugs are contraindicated or have substantial risks.Bristol Myers Squibb in collaboration with Ono Pharmaceutical.Copyright © 2022 Elsevier Ltd.

Blocking the interaction between PD-1 and its ligands is a promising treatment strategy for advanced hepatocellular carcinoma. This study aimed to assess the antitumour activity and safety of the anti-PD-1 inhibitor camrelizumab in pretreated patients with advanced hepatocellular carcinoma.This is a multicentre, open-label, parallel-group, randomised, phase 2 trial done at 13 study sites in China. Eligible patients were aged 18 years and older with a histological or cytological diagnosis of advanced hepatocellular carcinoma, had progressed on or were intolerant to previous systemic treatment, and had an Eastern Cooperative Oncology Group performance score of 0-1. Patients were randomly assigned (1:1) to receive camrelizumab 3 mg/kg intravenously every 2 or 3 weeks, via a centralised interactive web-response system using block randomisation (block size of four). The primary endpoints were objective response (per blinded independent central review) and 6-month overall survival, in all randomly assigned patients who had at least one dose of study treatment. Safety was analysed in all treated patients. This study is registered with ClinicalTrials.gov, number NCT02989922, and follow-up is ongoing, but enrolment is closed.Between Nov 15, 2016, and Nov 16, 2017, 303 patients were screened for eligibility, of whom 220 eligible patients were randomly assigned and among whom 217 received camrelizumab (109 patients were given treatment every 2 weeks and 108 every 3 weeks). Median follow-up was 12·5 months (IQR 5·7-15·5). Objective response was reported in 32 (14·7%; 95% CI 10·3-20·2) of 217 patients. The overall survival probability at 6 months was 74·4% (95% CI 68·0-79·7)]. Grade 3 or 4 treatment-related adverse events occurred in 47 (22%) of 217 patients; the most common were increased aspartate aminotransferase (ten [5%]) and decreased neutrophil count (seven [3%]). Two deaths were judged by the investigators to be potentially treatment-related (one due to liver dysfunction and one due to multiple organ failure).Camrelizumab showed antitumour activity in pretreated Chinese patients with advanced hepatocellular carcinoma, with manageable toxicities, and might represent a new treatment option for these patients.Jiangsu Hengrui Medicine.Copyright © 2020 Elsevier Ltd.

Angiogenesis is defined as the formation of new blood vessels from preexisting vessels and has been characterized as an essential process for tumor cell proliferation and viability. This has led to the development of pharmacological agents for anti-angiogenesis to disrupt the vascular supply and starve tumor of nutrients and oxygen, primarily through blockade of VEGF/VEGFR signaling. This effort has resulted in 11 anti-VEGF drugs approved for certain advanced cancers, alone or in combination with chemotherapy or other targeted therapies. But this success had only limited impact on overall survival of cancer patients and rarely resulted in durable responses. Given the recent success of immunotherapies, combinations of anti-angiogenics with immune checkpoint blockers have become an attractive strategy. However, implementing such combinations will require a better mechanistic understanding of their interaction. Due to overexpression of pro-angiogenic factors in tumors, their vasculature is often tortuous and disorganized, with excessively branched leaky vessels. This enhances vascular permeability, which in turn is associated with high interstitial fluid pressure, and a reduction in blood perfusion and oxygenation. Judicious dosing of anti-angiogenic treatment can transiently normalize the tumor vasculature by decreasing vascular permeability and improving tumor perfusion and blood flow, and synergize with immunotherapy in this time window. However, anti-angiogenics may also excessively prune tumor vessels in a dose and time-dependent manner, which induces hypoxia and immunosuppression, including increased expression of the immune checkpoint programmed death receptor ligand (PD-L1). This review focuses on revisiting the concept of anti-angiogenesis in combination with immunotherapy as a strategy for cancer treatment.

The immunomodulatory effect of lenvatinib (a multikinase inhibitor) on tumor microenvironments may contribute to antitumor activity when combined with programmed death receptor-1 (PD-1) signaling inhibitors in hepatocellular carcinoma (HCC). We report results from a phase Ib study of lenvatinib plus pembrolizumab (an anti-PD-1 antibody) in unresectable HCC (uHCC).In this open-label multicenter study, patients with uHCC received lenvatinib (bodyweight ≥ 60 kg, 12 mg; < 60 kg, 8 mg) orally daily and pembrolizumab 200 mg intravenously on day 1 of a 21-day cycle. The study included a dose-limiting toxicity (DLT) phase and an expansion phase (first-line patients). Primary objectives were safety/tolerability (DLT phase), and objective response rate (ORR) and duration of response (DOR) by modified RECIST (mRECIST) and RECIST version 1.1 (v1.1) per independent imaging review (IIR; expansion phase).A total of 104 patients were enrolled. No DLTs were reported (n = 6) in the DLT phase; 100 patients (expansion phase; included n = 2 from DLT phase) had received no prior systemic therapy and had Barcelona Clinic Liver Cancer stage B (n = 29) or C disease (n = 71). At data cutoff, 37% of patients remained on treatment. Median duration of follow-up was 10.6 months (95% CI, 9.2 to 11.5 months). Confirmed ORRs by IIR were 46.0% (95% CI, 36.0% to 56.3%) per mRECIST and 36.0% (95% CI, 26.6% to 46.2%) per RECIST v1.1. Median DORs by IIR were 8.6 months (95% CI, 6.9 months to not estimable [NE]) per mRECIST and 12.6 months (95% CI, 6.9 months to NE) per RECIST v1.1. Median progression-free survival by IIR was 9.3 months per mRECIST and 8.6 months per RECIST v1.1. Median overall survival was 22 months. Grade ≥ 3 treatment-related adverse events occurred in 67% (grade 5, 3%) of patients. No new safety signals were identified.Lenvatinib plus pembrolizumab has promising antitumor activity in uHCC. Toxicities were manageable, with no unexpected safety signals.

<b><i>Introduction:</i></b> Transarterial chemoembolization (TACE) is the standard treatment for unresectable intermediate-stage hepatocellular carcinoma (HCC), but recurrence after TACE is common. The present phase 2, prospective, multicenter, single-arm trial, the TACTICS-L trial, investigated the efficacy and safety of TACE plus lenvatinib (LEN), a drug that more strongly promotes vascular normalization and has a better objective response rate (ORR) than sorafenib (jRCTs031180074). <b><i>Methods:</i></b> Participants were patients with HCC who had not previously received systemic therapy, hepatic arterial infusion chemotherapy, or immunotherapy and who were ineligible for resection or percutaneous ablation therapy. LEN was to be administered 14–21 days before the first TACE, stopped 2 days before TACE, and resumed 3 days after TACE. Key inclusion criteria were unresectable HCC, Child-Pugh A liver function, 0–2 prior TACE sessions, tumor size ≤10 cm, number of tumors ≤10, and ECOG performance status 0–1. Key exclusion criteria were vascular invasion and extrahepatic spread. The primary endpoint was progression-free survival (PFS) by RECICL, and secondary endpoints were time to untreatable progression, ORR, overall survival (OS), and safety. <b><i>Results:</i></b> A total of 62 HCC patients were enrolled in this trial. The median age was 72 years, 77.4% of patients were men, and 95.2% had PS 0. The primary endpoint of median PFS was 28.0 months (90% confidence interval [CI] 25.1–31.0) after a minimum 24 months of follow-up. The secondary endpoint of median OS was not reached (90% CI 35.5 months–NR). LEN-TACE achieved a high response rate and high complete response (CR) rate (4 weeks after the first TACE: ORR 79.0%, CR rate 53.2%; best response: ORR 88.7%, CR rate 67.7%) by RECICL. Exploratory subgroup analyses showed that the characteristics of responders/nonresponders (ORR and CR rate) were similar and that LEN-TACE would be effective in all subgroups, including the population in whom TACE alone would be less likely to be curative (e.g., patients with the non-simple nodular type or a high tumor burden). The relative dose intensity of LEN before the first TACE was important for achieving higher CR rate/ORR by LEN-TACE. No new safety concerns were observed. <b><i>Conclusion:</i></b> The results of this trial provide encouraging evidence, supporting the efficacy and favorable safety profile of LEN-TACE in patients who are ineligible for locoregional therapy.

\n Hepatocellular carcinoma (HCC) can have viral or non-viral causes\n 1–5\n. Non-alcoholic steatohepatitis (NASH) is an important driver of HCC. Immunotherapy has been approved for treating HCC, but biomarker-based stratification of patients for optimal response to therapy is an unmet need\n 6,7\n. Here we report the progressive accumulation of exhausted, unconventionally activated CD8\n +\n PD1\n +\n T cells in NASH-affected livers. In preclinical models of NASH-induced HCC, therapeutic immunotherapy targeted at programmed death-1 (PD1) expanded activated CD8\n +\n PD1\n +\n T cells within tumours but did not lead to tumour regression, which indicates that tumour immune surveillance was impaired. When given prophylactically, anti-PD1 treatment led to an increase in the incidence of NASH–HCC and in the number and size of tumour nodules, which correlated with increased hepatic CD8\n +\n PD1\n +\n CXCR6\n +\n, TOX\n +\n, and TNF\n +\n T cells. The increase in HCC triggered by anti-PD1 treatment was prevented by depletion of CD8\n +\n T cells or TNF neutralization, suggesting that CD8\n +\n T cells help to induce NASH–HCC, rather than invigorating or executing immune surveillance. We found similar phenotypic and functional profiles in hepatic CD8\n +\n PD1\n +\n T cells from humans with NAFLD or NASH. A meta-analysis of three randomized phase III clinical trials that tested inhibitors of PDL1 (programmed death-ligand 1) or PD1 in more than 1,600 patients with advanced HCC revealed that immune therapy did not improve survival in patients with non-viral HCC. In two additional cohorts, patients with NASH-driven HCC who received anti-PD1 or anti-PDL1 treatment showed reduced overall survival compared to patients with other aetiologies. Collectively, these data show that non-viral HCC, and particularly NASH–HCC, might be less responsive to immunotherapy, probably owing to NASH-related aberrant T cell activation causing tissue damage that leads to impaired immune surveillance. Our data provide a rationale for stratification of patients with HCC according to underlying aetiology in studies of immunotherapy as a primary or adjuvant treatment.\n
