Tumor burden and liver function in HCC patient selection for selective internal radiation therapy: SARAH post-hoc study

Hepatocellular Carcinoma with Vascular Invasion Treated with Resin Yttrium-90 Transarterial Radioembolization Using Single Compartment Dosimetry

PURPOSE

To report outcomes in hepatocellular carcinoma (HCC) patients with lobar and segmental vascular invasion treated with resin Yttrium-90 transarterial radioembolization (Y90-TARE) with single-compartment MIRD (Medical Internal Radiation Dose) model.

MATERIALS AND METHODS

This was a retrospective IRB approved study of patients with a diagnosis of HCC with vascular invasion undergoing resin Y90-TARE from 2014 to 2022 (n = 61). Patients with Body Surface Area dosimetry (n = 20), main portal vein invasion (n = 6) and patients with an ECOG of > 2 were excluded (n = 1) with a final cohort of 34 patients.

RESULTS

Study population consisted of 34 patients, median age 62 years [60-71], tumor size 4.2 (2.8-7.4) cm, and 82% male. The median prescribed dose was 170 (126-200) Gy. The objective response rate at 6 months was 67% and disease control rate was 72%. The median survival was 18 months, median progression-free survival was 9.8 months. The 1- and 3-year survival rates were 76% and 57% in patients prescribed > 180 Gy, compared to 29% and 15% in patients with < 180 Gy (p = 0.01). Five of 15 Childs-Pugh A, ECOG < 1 patients (33%) were downstaged to resection, with complete pathologic necrosis in 40%, and 1 and 3-year survival rates of 100%. Grade-3 adverse events were seen in only 5/34 (15%), with no grade-4 or 5 adverse events.

CONCLUSION

Resin Y90-TARE using single compartment MIRD model for HCC with segmental and lobar vascular invasion can result in downstaging to resection in 33% of patients and higher prescribed doses (> 180 Gy) result in improved survival.

Transarterial Radioembolisation with Y90 Resin Microspheres and the Effect of Reimbursement Criteria in France: Final Results of the CIRT-FR Prospective Observational Study

PURPOSE

This analysis of the CIRSE Registry for SIR-Spheres Therapy in France, CIRT-FR, reports on real-world outcomes of transarterial radioembolisation (TARE) with Y90 resin microspheres for hepatocellular carcinoma (HCC) and colorectal cancer liver metastases (CRLM) patients in France, focusing on safety, effectiveness and health-related quality of life (HRQoL). Results on patients treated based on national reimbursement criteria are discussed here.

METHODS

Prospective, multicentre, observational study of HCC and CRLM patients treated between August 2017 and July 2020 with TARE Y90 resin microspheres. Patients were assigned to different analysis groups based on reimbursement recommendations. Follow-up period was at least 24 months with patient data collected every 3 months.

RESULTS

In total, 252 (193 HCC, 59 CRLM) patients of CIRT-FR were included in the analysis. No differences in effectiveness, safety and HRQoL were found between analysis groups based on reimbursement recommendations. Median overall survival for HCC and CRLM was 19.0 (95% CI, 16.1-22.4) and 10.8 (95% CI, 8.0-13.5) months, respectively. Serious procedure-related adverse events occurred in 13% of the patients. HRQoL generally remained stable, with some fluctuations in function scores and symptoms.

CONCLUSION

In our cohorts, patients performed similarly regarding clinical outcomes irrespective of their analysis group based on reimbursement recommendations. Our results suggest that instead of restrictive reimbursement criteria, more decision-making power in selecting suitable patient groups could be given to multidisciplinary tumour boards. Results confirm that TARE with Y90 resin microspheres is an effective and safe treatment for liver cancer, with maintained HRQoL in most patients.

The assessment of impaired liver function and prognosis in hepatocellular carcinoma

INTRODUCTION

The impairment of liver function strongly limits the therapeutic options for hepatocellular carcinoma (HCC), and the assessment of liver function is key to finding the appropriate therapy for patients suffering from this disease. Furthermore, preexisting liver dysfunction has a negative impact on the prognosis of patients in addition to the malignant potential of HCC. Hence, defining the optimal treatment of patients with HCC requires a comprehensive examination with liver function being a crucial part of it.

AREAS COVERED

This review will provide an overview of the currently existing methods for evaluating the liver function in patients with HCC. Assessment of liver function includes scoring systems but also functional and technical methods. In addition, the role of these tests in different treatment facilities such as liver resection, transplantation, interventional and systemic therapy is summarized.

EXPERT OPINION

A comprehensive pretherapeutic assessment of the liver function includes laboratory-based scoring systems, as well as imaging- and non-imaging-based functional tests. Combining diverse parameters can help to improve the safety and efficacy of HCC therapy particularly in patients with compromised liver function. Future research should focus on optimizing pretherapeutic assessment recommendations for each therapy.

[Modern TARE 2023 - from palliative care to a curative treatment alternative]

Selective internal radiotherapy (SIRT) or transarterial radioembolisation (TARE) is an alternative treatment for hepatocellular carcinoma (HCC) or hepatic metastatic colorectal carcinoma (mCRC) and is now anchored in many guidelines. The article summarises the current guidelines on SIRT/TARE in HCC and mCRC.

British Society of Gastroenterology guidelines for the management of hepatocellular carcinoma in adults

Deaths from the majority of cancers are falling globally, but the incidence and mortality from hepatocellular carcinoma (HCC) is increasing in the United Kingdom and in other Western countries. HCC is a highly fatal cancer, often diagnosed late, with an incidence to mortality ratio that approaches 1. Despite there being a number of treatment options, including those associated with good medium to long-term survival, 5-year survival from HCC in the UK remains below 20%. Sex, ethnicity and deprivation are important demographics for the incidence of, and/or survival from, HCC. These clinical practice guidelines will provide evidence-based advice for the assessment and management of patients with HCC. The clinical and scientific data underpinning the recommendations we make are summarised in detail. Much of the content will have broad relevance, but the treatment algorithms are based on therapies that are available in the UK and have regulatory approval for use in the National Health Service.

Cost-effectiveness of selective internal radiation therapy with Y-90 resin microspheres for intermediate- and advanced-stage hepatocellular carcinoma in Brazil

AimsHepatocellular carcinoma (HCC) is a severe condition with poor prognosis that places a significant burden on patients, caregivers, and healthcare systems. Selective internal radiation therapy (SIRT) is a treatment available to patients with HCC which addresses some of the limitations of alternative treatment options. A cost-effectiveness analysis was undertaken into the use of SIRT using Y-90 resin microspheres for the treatment of unresectable, intermediate- and late-stage HCC in Brazil.Materials and methodsA partitioned-survival model was developed, including a tunnel state for patients downstaged to receive treatments with curative intent. Sorafenib was the selected comparator, a common systemic treatment in Brazil and for which comparative evidence exists. Clinical data were extracted from published sources of pivotal trials, and effectiveness was measured in quality-adjusted life-years (QALYs) and life-years (LYs). The analysis was conducted from the Brazilian private payer perspective and a lifetime horizon was implemented. Comprehensive sensitivity analyses were conducted.ResultsLYs and QALYs were higher for SIRT with Y-90 resin microspheres versus sorafenib (0.27 and 0.20 incremental LYs and QALYs, respectively) and costs were slightly higher for SIRT (R$15,864). The base case incremental cost-effectiveness ratio (ICER) was R$77,602 per QALY. The ICER was mostly influenced by parameters defining the sorafenib overall survival curve and SIRT had a 73% probability of being cost-effective at a willingness-to-pay threshold of R$135,761 per QALY (three times the per-capita gross domestic product in Brazil). Overall, sensitivity analyses confirmed the robustness of the results indicating that SIRT with Y-90 resin microspheres is cost-effective compared with sorafenib.LimitationsA rapidly evolving treatment landscape in Brazil and worldwide, and the lack of local data for some variables were the main limitations.ConclusionsSIRT with Y-90 resin microspheres is a cost-effective option compared with sorafenib in Brazil.

Advances in Delivery of Selective Internal Radiation Therapy (SIRT): Economic and Logistical Effects of Same-Stay Work-Up and Procedure in the Treatment of Unresectable Liver Tumors in England

INTRODUCTION

Selective internal radiation therapy (SIRT) is a targeted method of treatment for unresectable liver tumors in which radiation therapy is directly delivered to the tumor(s) via the hepatic vasculature. Successful outcomes with SIRT are dependent on the specific vasculature of the liver and tumor, and the patient therefore needs to attend a "work-up" to map the hepatic vasculature prior to the SIRT procedure. Recent advances in SIRT delivery have enabled same-day or same-stay work-up and procedure, requiring only one hospital visit rather than two. We aimed to evaluate the economic, travel time, and transport-related environmental impact of a new brachytherapy device delivery program, the order-map-treat (OMT) program, in patients with unresectable hepatocellular carcinoma (HCC) in England.

METHODS

A healthcare resource group (HRG)-based analysis of costs from a national payer (Department of Health and Social Care, DHSC) perspective was conducted assuming that, with OMT, patients would have to attend hospital only once for both the SIRT work-up and procedure versus twice without OMT. Patient travel time and CO₂ emissions were then estimated by identifying the SIRT center closest to the centroid of each clinical commissioning group (CCG) and calculating straight-line distances with a "detour index" to capture the effect of indirect routes via road or rail.

RESULTS

It was estimated that 856 patients per annum would be eligible for SIRT treatment for unresectable HCC in England. OMT would be anticipated to save GBP 2842 per patient versus performing SIRT without OMT. Furthermore, across all patients with HCC eligible for SIRT in England, OMT would avoid 74,500 km of travel, 2299 h of travel time, and 13.9 metric tons of patient transport-related CO₂ emissions annually.

CONCLUSION

OMT reduces the number of hospital visits required for SIRT by 50%, resulting in financial savings from the DHSC perspective, time savings from the patient perspective, and reduced CO₂ emissions arising from patient transport.

ALBI grade for outcome prediction in patients affected by hepatocellular carcinoma treated with transarterial radioembolization

Introduction and aim

Diagnosis of hepatocellular carcinoma (HCC) often occurs when the disease is unresectable and therapeutic options are limited. The extent of disease and liver function according to Child-Pugh (C-P) classification are the main prognostic factors guiding clinicians in the management of HCC. The integration of albumin-bilirubin (ALBI) grade is emerging to assess liver function on account of its objectivity and reproducibility. Our aim was to investigate the value of the ALBI grade in predicting the outcome in patients treated with transarterial radioembolization (TARE).

Methods

We retrospectively enrolled patients with advanced and unresectable HCC treated with TARE in our institution. All patients underwent a preliminary dosimetric study before Yttrium-90 resin microsphere TARE. Barcelona Clinic Liver Cancer (BCLC), C-P, and ALBI scores were established at the time of TARE. Overall survival (OS), progression-free survival (PFS), and survival after TARE were assessed with the Kaplan-Meier method. Survival analyses were stratified according to ALBI grade, C-P, and BCLC classification. Univariate and multivariate Cox proportional regression models determined the association between prognostic factors and clinical outcomes.

Results

In total, 72 patients were included in the study, showing an OS of 51 months. The ALBI grade identified groups of patients with different prognoses both in the whole cohort and within the C-P classes, especially between ALBI 1 and ALBI 2. This result is confirmed also within BCLC classes. In treatment naïve patients, the ALBI grade was not able to predict outcomes, whereas the presence and degree of portal vein thrombosis (PVT) significantly affected prognosis.

Conclusions

The ALBI grade provided a more accurate prognostic stratification than the C-P classification in patients with intermediate and advanced HCC treated with TARE. However, the outcome of HCC is affected not only by liver function but also by disease-related characteristics, such as disease burden and degree of PVT. Including the ALBI grade in clinical guidelines may improve the management of patients affected by HCC.

The importance of liver functional reserve in the non-surgical treatment of hepatocellular carcinoma

The aim of any oncological treatment is not just to eliminate the tumour, but to maximise patient survival and quality of life. Since the liver has a vital function, any radical treatment that severely compromises liver function will result in a shortening of life expectancy, rather than a prolongation. Furthermore, even non-severe liver damage may prevent the delivery of further effective therapies. This is particularly important in the case of hepatocellular carcinoma (HCC), as it is associated with underlying cirrhosis in most patients - cirrhosis itself is not only a potentially lethal disease and independent prognostic factor in HCC, but it also makes liver function fragile. Accordingly, some information about liver dysfunction is included in most staging systems for HCC and can be used to guide the selection of treatments that the functional liver reserve can tolerate. Unfortunately, the prediction of functional damage to the liver in the case of antitumor treatments is very challenging and still suboptimal in any given patient. Moreover, while the assessment of functional reserve can now be used to avoid postoperative liver failure in the surgical setting, its use has been less well clarified for non-surgical therapies, which is of particular relevance today, as several lines of effective non-surgical treatments, including systemic therapies, have become available. The present article will a) critically review the implications of the assessment of liver functional reserve in patients with HCC, b) illustrate the available tools to assess liver functional reserve and c) discuss the role of functional assessment for each type of non-surgical therapy for HCC.

The Cost-Effectiveness of Selective Internal Radiation Therapies Compared With Sorafenib for Treating Advanced Unresectable Hepatocellular Carcinoma in the United Kingdom

OBJECTIVES

To assess the cost-effectiveness of selective internal radiation therapy (SIRT) compared with sorafenib for the treatment of patients with advanced hepatocellular carcinoma in the United Kingdom, including a selected subgroup of patients who have been identified as benefiting from treatment with SIRT.

METHODS

A de novo economic model was developed comparing SIRT with sorafenib using data from two large randomized controlled trials. The model structure comprised a decision tree representing the outcome of the work-up procedure, transitioning into a 3-state partitioned survival model to project long-term survival outcomes. Cost-effectiveness in a post hoc defined subgroup with low tumor burden and good liver function was explored.

RESULTS

At list price, SIRT was predicted to be less costly but less effective than sorafenib with an estimated saving of £156 089 per quality-adjusted life-year forgone, with cost savings of £4589 and 0.029 fewer quality-adjusted life-years than sorafenib. Accounting for existing confidential discounts for sorafenib, two SIRTs were cost-effective at a £30 000 willingness-to-pay threshold compared with sorafenib when a discount for the technologies was introduced. In the subgroup with low tumor burden and good liver function, SIRT may be associated with greater survival benefits and cost savings.

CONCLUSIONS

Accounting for confidential discounts, on average, SIRT technologies represent value for money in the whole advanced hepatocellular carcinoma population, being less effective but less costly than sorafenib. Results from a subgroup with low tumor burden and good liver function suggest that the cost-effectiveness of SIRTs may be maximized in this group, but further research is required to demonstrate the validity of effectiveness benefits.

SIRT in 2025

Selective internal radiation therapy represents an endovascular treatment option for patients with primary liver malignancies, in different clinical stages. Potential applications of this treatment are in early-stage hepatocellular carcinoma, as a curative option, or in combination with systemic treatments in intermediate and advanced-stages. This review, based on existing literature and ongoing trials, will focus on the future of this treatment in patients with hepatocellular carcinoma, in combination with systemic treatments, or with the use of new devices and technological developments; it will also describe new potential future indications and structural and organizational perspectives.

Prognostic value of baseline imaging and clinical features in patients with advanced hepatocellular carcinoma

Aims

To investigate the prognostic value of baseline imaging features for overall survival (OS) and liver decompensation (LD) in patients with hepatocellular carcinoma (HCC).

Design

Patients with advanced HCC from the SORAMIC trial were evaluated in this post hoc analysis. Several radiological imaging features were collected from baseline computed tomography (CT) and magnetic resonance imaging (MRI) imaging, besides clinical values. The prognostic value of these features for OS and LD (grade 2 bilirubin increase) was quantified with univariate Cox proportional hazard models and multivariate Least Absolute Shrinkage and Selection Operator (LASSO) regression.

Results

Three hundred and seventy-six patients were included in this study. The treatment arm was not correlated with OS. LASSO showed satellite lesions, atypical HCC, peritumoral arterial enhancement, larger tumour size, higher albumin–bilirubin (ALBI) score, liver–spleen ratio <1.5, ascites, pleural effusion and higher bilirubin values were predictors of worse OS, and higher relative liver enhancement, smooth margin and capsule were associated with better OS. LASSO analysis for LD showed satellite lesions, peritumoral hypointensity in hepatobiliary phase, high ALBI score, higher bilirubin values and ascites were predictors of LD, while randomisation to sorafenib arm was associated with lower LD.

Conclusions

Imaging features showing aggressive tumour biology and poor liver function, in addition to clinical parameters, can serve as imaging biomarkers for OS and LD in patients receiving sorafenib and selective internal radiation therapy for HCC.

Effects of Trial Population Selection on Quality of Life and Healthcare Decision-Making: A Systematic Review and Example in the Treatment of Hepatocellular Carcinoma with Radioembolization

Background and Aims

Quality of life is among the most important considerations in the treatment of hepatocellular carcinoma (HCC), arguably second only to overall survival. Measuring and modeling patient quality of life is also crucial in the evaluation of the cost-effectiveness of health interventions. In the present study, we aimed to identify cost-utility analyses comparing selective internal radiation therapy (SIRT) with systemic therapy in patients with unresectable HCC and to compare the modeled incremental quality of life differences between the two therapies.

Methods

A systematic literature review was conducted. PubMed, EMBASE, the Cochrane Library, and health technology assessment agency websites were searched to identify cost–utility studies of SIRT versus systemic therapies in the treatment of HCC. Key characteristics of the studies, modeled populations and incremental quality of life outcomes were extracted from the included studies.

Results

The systematic literature review retrieved 1140 studies, of which four were ultimately included. Hand searches then identified two distinct analyses, and an updated version of one of the four studies identified initially. From these seven studies, 18 analyses were included. Analyses using data from the overall trial populations reported incremental quality-of-life estimates spanning −0.09 to +0.28 quality-adjusted life years (QALYs), with that range expanding to −0.09 to +0.60 QALYs when also considering post hoc sub-group analyses.

Conclusion

The wide range of incremental QALYs, with substantial differences between overall trial populations and subgroups, illustrates the impact that the choice of target population may have on the relative quality of life outcomes of the compared interventions, which may in turn affect clinical decision-making. The small differences also highlight both the importance of reporting measures of dispersion around the findings, and the limitations of the incremental cost-effectiveness ratio (ICER) for assessing the relative cost-effectiveness of interventions that are predicted to result in similar quality-of-life outcomes.

Prognostic factors of unresectable hepatocellular carcinoma treated with yttrium-90 radioembolization: results from a large cohort over 13 years at a single center

Background

A previous study of patients with unresectable hepatocellular carcinoma (HCC) was extended to further examine factors associated with overall survival (OS) after selective internal radiation therapy with yttrium-90 resin microspheres (Y90 SIRT).

Methods

Data from patients of any age diagnosed with unresectable HCC and treated with Y90 SIRT at our institution from 2004 through 2017 were retrospectively analyzed. Among other criteria, patients had to have Eastern Cooperative Oncology Group performance status 0 to 2, not have received Y90 SIRT previously, and not have extrahepatic disease. Primary outcome was OS; secondary outcomes included tumor response and adverse events (AEs). Kaplan-Meier survival analyses and multivariable Cox proportional hazards models were used to evaluate prognostic factors for OS.

Results

Of the 226 patients, 59% were White, 77% were male, and the mean age at first SIRT procedure was 65.1±9.4 years. More than half had received previous treatment for HCC. The most common etiology was hepatitis C (n=138/224 available, 62%), followed by alcohol use (n=45, 20%), and nonalcoholic steatohepatitis (n=27, 12%). The mean model for end-stage liver disease score at baseline was 8.8±2.2. Patients were followed-up for a median of 12.2 months (95% CI, 0.0-62.6). Median OS was 16.6 months (95% CI, 13.1 to not reached). Bilobar disease, higher albumin-bilirubin score at baseline, prior treatment with sorafenib, alcohol use etiology, and higher administered dose were associated with shorter survival, whereas subsequent liver transplant [in 26 patients (11.5%)] was associated with longer survival. Of the 186 patients with AEs data, 75 (40.3%) patients reported an event and, of these, 13 (17.3%) patients had grade 4 bilirubin values.

Conclusions

In a large, diverse population treated at a single center over 13 years, Y90 SIRT produced a median OS of 16.6 months in patients with unresectable HCC and enabled subsequent transplantation in a subset of patients. Factors affecting the length of survival should be considered when making treatment decisions for unresectable HCC.

Changes in treatment pattern and costs in advanced hepatocellular carcinoma (HCC)

INTRODUCTION

While essential for cost-effectiveness analyses, there are no current resource use and cost data available for advanced hepatocellular carcinoma (HCC) and selective internal radiation therapy (SIRT). The study aims to assess current resource use and costs in HCC and for SIRT compared to historical survey data.

AREAS COVERED

To address this data gap, resource use was elicited via surveys and interviews with medical professionals experienced with HCC and SIRT in the United Kingdom. Unit costs were from publicly available databases. Resource use and costs were estimated and compared to prior surveys.

EXPERT OPINION

From eleven responses, pre-progression costs for SIRT and systemic therapy were £256.77 and £292.27/month, respectively. One-off progression and post-progression costs were £209.98 and £522.84/month. Monthly costs were 54%-79% lower than in previous surveys, due to reduction in hospitalizations and funded social care. Furthermore, substantial differences in resource use associated with SIRT between clinical practice and clinical trials were found. In conclusion, increased availability and familiarity with systemic treatments has led to important changes in HCC care and SIRT administration. The uncertainty from the use of expert opinion and the limited number of hospitals with SIRT experience can be addressed with future research using large databases, registries.

A systematic literature review and network meta-analysis of first-line treatments for unresectable hepatocellular carcinoma based on data from randomized controlled trials

BACKGROUND

Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer. First-line treatment options for unresectable HCC include sorafenib, lenvatinib, selective internal radiation therapy (SIRT), and transarterial chemoembolization (TACE). The present study reviewed randomized controlled trials (RCTs) of first-line therapies for unresectable HCC in TACE-ineligible patients.

RESEARCH DESIGN AND METHODS

A systematic literature review (SLR) was conducted to identify RCTs of first-line treatments for TACE-ineligible patients with unresectable HCC. Data on overall survival (OS) and progression-free survival were extracted and a contrast-based Bayesian network meta-analysis (NMA) was conducted using Markov Chain Monte Carlo techniques.

RESULTS

The SLR identified three RCTs: two comparing Y-90 resin microspheres with sorafenib, and one comparing sorafenib with lenvatinib. No RCTs were identified comparing other SIRT technologies with any other approved first-line HCC therapies. The NMA showed no significant OS differences between Y-90 resin microspheres and sorafenib (hazard ratio [HR] 0.92, 95% credible interval [CrI]: 0.79-1.08) or lenvatinib (HR: 0.88, 95% CrI: 0.63-1.22).

CONCLUSIONS

An SLR and NMA showed no significant differences between sorafenib, lenvatinib, and Y-90 resin microspheres in treating unresectable HCC. RCT evidence was not available for any other SIRT technologies and an evaluation of their relative efficacy was therefore not possible.

Cost-utility analysis of selective internal radiation therapy with Y-90 resin microspheres in hepatocellular carcinoma

Background: The study assessed the cost-utility of selective internal radiation therapy (SIRT) with Y-90 resin microspheres versus sorafenib in UK patients with unresectable hepatocellular carcinoma ineligible for transarterial chemoembolization. Materials & methods: A lifetime partitioned survival model was developed for patients with low tumor burden (≤25%) and good liver function (albumin-bilirubin grade 1). Efficacy, safety and quality of life data were from a European Phase III randomized controlled trial and published studies. Resource use was from registries and clinical surveys. Results: Discounted quality-adjusted life-years were 1.982 and 1.381, and discounted total costs were £29,143 and 30,927, for SIRT and sorafenib, respectively. Conclusion: SIRT has the potential to be a dominant (more efficacious/less costly) or cost-effective alternative to sorafenib in patients with unresectable hepatocellular carcinoma.

Neutrophil to lymphocyte ratio and albumin bilirubin grade in hepatocellular carcinoma: A systematic review

BACKGROUND

Hepatocellular carcinoma (HCC) is a frequent cause of cancer related death globally. Neutrophil to lymphocyte ratio (NLR) and albumin bilirubin (ALBI) grade are emerging prognostic indicators in HCC.

AIM

To study published literature of NLR and ALBI over the last five years, and to validate NLR and ALBI locally in our centre as indicators of HCC survival.

METHODS

A systematic review of the published literature on PubMed of NLR and ALBI in HCC over the last five years. The search followed the guidelines of the preferred reporting items for systematic reviews and meta-analyses. Additionally, we also investigated HCC cases between December 2013 and December 2018 in our centre.

RESULTS

There were 54 studies describing the relation between HCC and NLR and 95 studies describing the relation between HCC and ALBI grade over the last five years. Our local cohort of patients showed NLR to have a significant negative relationship to survival (P = 0.011). There was also significant inverse relationship between the size of the largest HCC nodule and survival (P = 0.009). Median survival with alpha fetoprotein (AFP) < 10 KU/L was 20 mo and with AFP > 10 KU/L was 5 mo. We found that AFP was inversely related to survival, this relationship was not statically significant (P = 0.132). Mean survival for ALBI grade 1 was 37.7 mo, ALBI grade 2 was 13.4 months and ALBI grade 3 was 4.5 mo. ALBI grades performed better than Child Turcotte Pugh score in detecting death from HCC.

CONCLUSION

NLR and ALBI grade in HCC predict survival better than the conventional alpha fetoprotein. ALBI grade performs better than Child Turcotte Pugh score. These markers are done as part of routine clinical care and in cases of normal alpha fetoprotein, these markers could give a better understanding of the patient disease progression. NLR and ALBI grade could have a role in modified easier to learn staging and prognostic systems for HCC.

Drug-eluting beads transarterial chemoembolization with CalliSpheres microspheres for treatment of unresectable intrahepatic cholangiocarcinoma

Objective: This study aimed to evaluate the efficacy and safety of doxorubicin-loaded drug-eluting beads transarterial chemoembolization (DEB-TACE) with CalliSpheres microspheres (CSM) in treating unresectable intrahepatic cholangiocarcinoma (ICC).

Methods: 88 unresectable ICC patients who received DEB-TACE treatment with CSM were retrospectively enrolled in this study. Information about treatment response, survival and adverse events were collected. The Kaplan-Meier curve was used to evaluate progression-free survival (PFS) and overall survival (OS), and factors affecting OS were determined by Cox's proportional hazards regression model.

Results: Tumor response of the whole sample of 88 patients was partial response (PR) in 58 (65.9%) patients, stable disease (SD) in 19 (21.6%) and progressive disease (PD) in 11 (12.5%) at one month after therapy, with no complete responses (CR). The median PFS and OS were 3.0 months and 9.0 months respectively. Cox's proportional hazards regression analysis disclosed that subsequent treatment was an independent favorable prognostic factor, while cholangiectasis, extensive intrahepatic tumor burden and extrahepatic metastasis were the three prognostic factors associated with poor survival in ICC patients. Besides, common adverse events included nausea/vomiting, abdominal pain and transient elevation of liver transaminase in patients treated by DEB-TACE with CSM.

Conclusion: DEB-TACE with CSM is safe and well-tolerated for unresectable ICC patients, with a low complication rate and a relative benefit in terms of survival. Subsequent treatments including systemic/loco-regional treatments is an independent favorable prognostic factor, but cholangiectasis, extensive intrahepatic tumor burden and extrahepatic metastases are the three prognostic factors associated with poor survival.

Embolotherapeutic Strategies for Hepatocellular Carcinoma: 2020 Update

Hepatocellular carcinoma (HCC) represents a significant contributor to cancer-related morbidity and mortality with increasing incidence in both developing and developed countries. Embolotherapy as a locoregional therapeutic strategy consists of trans-arterial or “bland” embolization (TAE), trans-arterial chemoembolization (TACE), and selective internal radiotherapy (SIRT). Trans-catheter arterial therapies can be applied along all stages of HCC, either as an alternative or neoadjuvant to surgical resection/transplantation in very early and early stage HCC or as a palliative option for local disease control in unresectable and advanced stage HCC. In advanced stage HCC, SIRT did not demonstrate superiority in comparison to systemic treatment options in several recent large prospective trials, though for carefully selected patients, may confer improved tolerability with similar disease control rates. The latest embolotherapeutic techniques and literature as they pertain to the management of HCC, as well as future directions, are reviewed in this article.
