Value of HCC-MELD Score in Patients With Hepatocellular Carcinoma Undergoing Liver Transplantation

Appraisal of a newly developed ALBI-sarcopenia score as a prognostic marker in patients with hepatocellular carcinoma

OBJECTIVE

This study aimed to evaluate the impact of the combined Albumin-bilirubin (ALBI)/sarcopenia score as a newly developed prognostic model for hepatocellular carcinoma (HCC), with a focus on its utility in predicting mortality.

METHODS

This prospective study was conducted on HCC patients who were followed for 1 year or until death. Sarcopenia was assessed radiologically by computed tomography at the level of L3. The study consisted of two sets: a development set in which the new ALBI-sarcopenia score was created, comprising 262 HCC patients, followed by an internal validation set with 100 patients.

RESULTS

The development cohort primarily included males (69.5%), aged 59.6 ± 8.09 years. In patients with sarcopenia, the ALBI score was -2.03 ± 0.42 ( P  < 0.006), the model for end-stage liver disease (MELD) score was 11.29 ± 2.43 ( P  < 0.001*), and the MELD-sarcopenia score was 21.29 ± 2.43 ( P  < 0.001*). The distribution of barcelona clinic liver cancer (BCLC) staging was as follows: BCLC A 18 (15.9%), BCLC B 63 (55.8%) and BCLC C 32 (28.3%) ( P  < 0.001*), with a notable association with higher mortality ( P  < 0.001). Multivariate analysis identified sarcopenia and ALBI scores as independent predictors of mortality in HCC ( P  < 0.001*). In the development set, the ALBI-sarcopenia score successfully predicted mortality at a cutoff >-11 with an area under a curve of 0.837 (95% CI, 0.784-0.889), while in the validation set, it predicted mortality at a cutoff >-11.55 with an area under a curve of 0.842 (95% CI, 0.753-0.930).

CONCLUSION

The newly introduced ALBI-sarcopenia score has demonstrated superior effectiveness in comparison to MELD-sarcopenia score, overcoming the shortcomings associated MELD score in forecasting outcomes for patients with HCC.

Consensus on the tertiary prevention of primary liver cancer

To effectively prevent recurrence, improve the prognosis and increase the survival rate of primary liver cancer (PLC) patients with radical cure, the Chinese Society of Hepatology, Chinese Medical Association, invited clinical experts and methodologists to develop the Consensus on the Tertiary Prevention of Primary Liver Cancer, which was based on the clinical and scientific advances on the risk factors, histopathology, imaging finding, clinical manifestation, and prevention of recurrence of PLC. The purpose is to provide a current basis for the prevention, surveillance, early detection and diagnosis, and the effective measures of PLC recurrence.

Clinical consensus statement: Establishing the roles of locoregional and systemic therapies for the treatment of intermediate-stage hepatocellular carcinoma in Canada

BACKGROUND

Hepatocellular carcinoma (HCC) a leading cause of cancer mortality worldwide and approximately one-third of patients present with intermediate-stage disease. The treatment landscape of intermediate-stage HCC is rapidly evolving due to developments in local, locoregional and systemic therapies. Treatment recommendations focused on this heterogenous disease stage and that take into account the Canadian reality are lacking. To address this gap, a pan-Canadian group of experts in hepatology, transplant, surgery, radiation therapy, nuclear medicine, interventional radiology, and medical oncology came together to develop consensus recommendations on management of intermediate-stage HCC relevant to the Canadian context.

METHODS

A modified Delphi framework was used to develop consensus statements with strengths of recommendation and supporting levels of evidence graded using the AHA/ACC classification system. Tentative consensus statements were drafted based on a systematic search and expert input in a series of iterative feedback cycles and were then circulated via online survey to assess the level of agreement.

RESULTS & CONCLUSION

The pre-defined ratification threshold of 80 % agreement was reached for all statements in the areas of multidisciplinary treatment (n = 4), intra-arterial therapy (n = 14), biologics (n = 5), radiation therapy (n = 3), surgical resection and transplantation (n = 7), and percutaneous ablative therapy (n = 4). These generally reflected an expansion in treatment options due to developments in previously established or emergent techniques, introduction of new and more active therapies and increased therapeutic flexibility. These developments have allowed for greater treatment tailoring and personalization as well as a paradigm shift toward strategies with curative intent in a wider range of disease settings.

Prediction models of hepatocellular carcinoma recurrence after liver transplantation: A comprehensive review

Liver transplantation (LT) is one of the most effective treatments for hepatocellular carcinoma (HCC). Although LT eliminates HCC and greatly reduces recurrence, some patients experience recurrence after LT. Criteria and models for screening patients with a high probability of HCC recurrence after LT, starting with the Milan criteria, have been published. These models have changed over time, but a standard has not been established. We summarized HCC prediction models after LT by focusing on the application of radiologic, serologic, and pathologic factors and recent trends. This review will look at studies that are based on living donor LT and deceased donor LT, as well as studies that downstaging procedures have been performed preoperatively. This ultimately aims to help make decisions for evaluating the HCC state and selecting candidates for LT according to the circumstances of each transplantation center.

Patient stratification in hepatocellular carcinoma: impact on choice of therapy

INTRODUCTION

HCC comprises around 60 to 80% of all primary liver cancers and exhibits wide geographical variability. Appropriate treatment allocation needs to include both patient and tumor characteristics.

AREAS COVERED

Current HCC classification systems to guide therapy are either liver function-centric and evaluate physiologic liver function to guide therapy or prognostic stratification classification systems broadly based on tumor morphologic parameters, patient performance status, and liver reserve assessment. This review focuses on different classification systems for HCC, their strengths, and weaknesses as well as the use of artificial intelligence in improving prognostication in HCC.

EXPERT OPINION

Future HCC classification systems will need to incorporate clinic-pathologic data from a multitude of sources and emerging therapies to develop patient-specific treatment plans targeting a patient's unique tumor profile.

Life Expectancy after Liver Transplantation for Non-Cirrhotic Hepatocellular Carcinoma

BACKGROUND

Hepatocelluar carcinoma typically occurs with underlying cirrhosis. However roughly 20% of cases arise in a non-cirrhotic liver. There is limited literature that addresses the long-term survival of the narrow subgroup who received transplantation. For such patients we sought to calculate life expectancies both at time of transplant and several years later, stratified by key risk factors, and to determine if survival has improved in recent years. Such information can be helpful in making treatment decisions.

METHODS

Data on 4,373 non-cirrhotic HCC patients who underwent liver transplantation in the MELD era (2002-2018) from the United States OPTN database were analyzed using the Cox proportional hazards regression model and life table methods.

RESULTS

Demographic and past medical history factors related to survival were patient age, donor age over 20, and the presence of ascites or severe hepatic encephalopathy. Survival did not vary by race or sex. HCC-specific factors significantly related to survival were the total number of tumors, extrahepatic spread, lymph node involvement, satellite lesions, micro- or macrovascular invasion, tumor differentiation (grade), and pre-transplant treatment. Survival improved over the study period, at 4% per calendar year during the first 5 years post transplant and 1% per year thereafter.

CONCLUSIONS

Life expectancy in non-cirrhotic HCC transplant patients is much reduced from normal, and varies according to age and tumor-related factors. Survival improved modestly over the study period.

Life Expectancy After Liver Transplantation for Hepatocellular Carcinoma With Cirrhosis

BACKGROUND

Hepatocelluar carcinoma, the most common primary liver cancer, has a historically dire prognosis. For hepatic cancer patients with cirrhosis who underwent liver transplantation, we sought to calculate life expectancies both at time of transplant and several years later, stratified by some key variables, and to determine if survival has improved in recent years.

METHODS

Data on 13,797 hepatic cancer patients with cirrhosis who underwent liver transplantation in the MELD era (2002-2018) from the US Organ Procurement and Transplantation Network database were analyzed using the Cox proportional hazards regression model and life table methods.

RESULTS

The major factors related to survival were age, donor age, transplant year, diabetes, functional status, and the presence of severe hepatic encephalopathy. Survival was significantly worse with increasing age and decreasing functional status level. There was no significant difference in survival between males and females. Survival improved over the study period, at 5% per calendar year during the first 5 years post transplant, and 1% per year thereafter.

CONCLUSIONS

Life expectancies were markedly reduced from normal, even among 5-year survivors with the most favorable characteristics. Survival improved modestly over the years 2002-2018.

Locoregional Therapy Approaches for Hepatocellular Carcinoma: Recent Advances and Management Strategies

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and third leading cause of cancer-related mortality worldwide. While surgical resection and transplantation are the standard first-line treatments for early-stage HCC, most patients do not fulfill criteria for surgery. Fortunately, catheter-directed and percutaneous locoregional approaches have evolved as major treatment modalities for unresectable HCC. Improved outcomes have been achieved with novel techniques which can be employed for diverse applications ranging from curative-intent for small localized tumors, to downstaging or bridging to resection and transplantation for early and intermediate disease, and locoregional control and palliation for advanced disease. This review explores recent advances in liver-directed techniques for HCC including bland transarterial embolization, chemoembolization, radioembolization, and ablative therapies, with a focus on patient selection, procedural technique, periprocedural management, and outcomes.

Progress in hepatectomy for hepatocellular carcinoma and peri-operation management

The global incidence of liver cancer continues to grow. Liver cancer, especially hepatocellular carcinoma, has high recurrence and mortality rates. Here, we review the past decade's diagnostic, therapeutic, and management strategies for hepatocellular carcinoma, and summarize new patient management approaches, including enhanced recovery after surgery, targeted therapy, and immunotherapy. We compare traditional and innovative management methods, which comprise developments in precision medicine, and consider their limitations. Ongoing innovation and technological advances enable surgeons to gain deeper understandings of the multidimensionality of hepatocellular carcinoma, thereby promoting the continuous development of precision therapy.

Comparing various scoring system for predicting overall survival according to treatment modalities in hepatocellular carcinoma focused on Platelet-albumin-bilirubin (PALBI) and albumin-bilirubin (ALBI) grade: A nationwide cohort study

BACKGROUND

We evaluated the ability of various grading scales including platelet-albumin-bilirubin (PALBI) and albumin-bilirubin (ALBI) grades to predict overall survival (OS) according to treatment modality in patients with hepatocellular carcinoma (HCC).

METHODS

The cohort of 6,669 patients with HCC was selected randomly from the 2008-2012 national cohort of the Korean Central Cancer Registry. The OS of 6,507 of these patients was evaluated using the Child-Turcotte-Pugh (CTP) class, Model for End-stage Liver Disease (MELD) score, and ALBI and PALBI grades.

RESULTS

The patient's mean age was 59.7 years. The most patients were hepatitis B virus (63.4%) and CTP class A (71.8%). The median OS durations of PALBI grade1 (38.4%), grade2 (33.2%), and grade3 (28.4%) patients were 81, 30, and 5 months, respectively (P<0.001). The PALBI grade had a larger area under the receiver operator characteristic curve (AUC) than did the CTP class, MELD score, and ALBI grade (overall AUC: 0.675 vs. 0.633, 0.645, and 0.642, respectively; P < 0.001). Moreover, the PALBI and ALBI grades enabled sub-classification of CTP A patients (P < 0.001). In a multivariate analysis, the PALBI and ALBI grades were significant risk factors for OS (P < 0.05). According to treatment modality, the PALBI grade was predictive of OS in patients receiving transarterial chemoembolization or supportive care. The ALBI grade was predictive of OS in patients undergoing surgical resection or radiofrequency ablation.

CONCLUSION

The PALBI and ALBI grades are more reliable for accessing liver function and predicting OS in patients with HCC. Moreover, according to treatment modality, appropriate use of the ALBI and PALBI grades will enable accurate determination of the prognosis of patients with HCC.

Selecting patients with hepatocellular carcinoma for liver transplantation: incorporating tumor biology criteria

Liver transplantation (LT) is the optimal therapeutic option for patients with liver cirrhosis and hepatocellular carcinoma (HCC). Due to universal donor shortage, only the patients with limited tumor burden (under the so-called Milan criteria) are considered as potential candidates for LT in most institutions. It is expected that in the near future, more liver grafts will be available for patients with HCC due to the implementation of new direct antivirals against hepatitis C, leaving a prone scenario to consider expanding Milan criteria. A moderate expansion of Milan criteria could be implemented without increasing the risk of tumor recurrence if patients with favorable biological behavior are carefully selected. Incorporating information regarding tumor biology in the decision-making algorithm would result in a more rational use of LT in patients with HCC. In the present review, surrogate markers of tumor biology are critically evaluated as potential tools to be combined with existing radiological criteria. In addition, the current state of liquid biopsy is discussed, as this cutting-edge technology may reshape the management of HCC in the upcoming years.
