Intermediate stage hepatocellular carcinoma: a summary review

BioPearl™ doxorubicin microspheres for unresectable HCC: a prospective, single-arm, multicenter study: BIOPEARL-ONE

Drug-eluting microsphere transarterial chemoembolization (DEM-TACE) reduces systemic exposure to chemotherapeutic drugs compared with conventional TACE but permanently occludes the embolized vessels, potentially obviating the possibility of re-treatment with TACE. Temporary embolization by resorbable BioPearl™ microspheres might facilitate subsequent re-treatments. We herein describe the trial protocol of BIOPEARL-ONE, a prospective, single-arm, multicenter, post-market clinical follow-up study. The primary objectives are technical success and safety following the use. DEM-TACE with doxorubicin-loaded BioPearl™ for unresectable hepatocellular carcinoma (HCC). The secondary objectives are tumor response, duration of response, progression-free survival, and survival rate at 18 months. Fifty patients with HCC nodules smaller than 5 cm and within the up-to-7 criteria will be enrolled.Clinical Trial Registration: NCT05911633.

Machine Learning for Dynamic Prognostication of Patients With Hepatocellular Carcinoma Using Time-Series Data: Survival Path Versus Dynamic-DeepHit HCC Model

Objectives

Patients with intermediate or advanced hepatocellular carcinoma (HCC) require repeated disease monitoring, prognosis assessment and treatment planning. In 2018, a novel machine learning methodology "survival path" (SP) was developed to facilitate dynamic prognosis prediction and treatment planning. One year after, a deep learning approach called Dynamic Deephit was developed. The performance of the two state-of-art models in dynamic prognostication have not been compared.

Methods

We trained and tested the SP and Dynamic DeepHit models in a large cohort of 2511 HCC patients using time-series data. The time-series data were converted into data of time slices, with an interval of three months. The time-dependent c-index for OS at given prediction time (t = 1, 6, 12, 18 months) and evaluation time (∆t = 3, 6, 9, 12, 18, 24, 36, 48 months) were compared.

Results

The comparison between SP model and Dynamic DeepHit-HCC model showed the latter had significant better performance at the time of initial admission. The time-dependent c-index of Dynamic DeepHit-HCC model gradually decreased with the extension of time (from 0.756 to 0.639 in the training set; from 0.787 to 0.661 in internal testing set; from 0.725 to 0.668 in multicenter testing set); while the time-dependent c-index of SP model displayed an increased trend (from 0.665 to 0.748 in the training set; from 0.608 to 0.743 in internal testing set; from 0.643 to 0.720 in multicenter testing set). When the prediction time comes to 6 months or later since initial treatment, the survival path model outperformed the dynamic DeepHit model at late evaluation times (∆t > 12 months).

Conclusions

This research highlighted the unique strengths of both models. The SP model had advantage in long term prediction while the Dynamic DeepHit-HCC model had advantages in prediction at near time points. Fine selection of models is needed in dealing with different scenarios.

Liver Resection Criteria for Patients with Hepatocellular Carcinoma and Multiple Tumors Based on Total Tumor Volume

BACKGROUND

In many Asian hepatocellular carcinoma (HCC) guidelines, resection is an option for multiple HCCs. It is difficult to compare small but multiple tumors vs. fewer large tumors in terms of the traditional tumor burden definition. We aimed to evaluate the role of liver resection for multiple HCCs and determine factors associated with survival benefits.

METHODS

We reviewed 160 patients with multiple HCCs who underwent liver resection between July 2003 and December 2018. The risk factors for tumor recurrence were assessed using Cox proportional hazards modeling, and survival was analyzed using the Kaplan-Meier method.

RESULTS

In all 160 patients, 133 (83.1%) exceeded the Milan criteria. Total tumor volume (TTV) > 275 cm3 and serum alpha-fetoprotein (AFP) level > 20 ng/mL were associated with disease-free survival. Patients beyond the Milan criteria were grouped into three risk categories: no risk (TTV ≤ 275 cm3 and AFP ≤ 20 ng/mL, n = 39), one risk (either TTV > 275 cm3 or AFP > 20 ng/mL, n = 76), and two risks (TTV > 275 cm3 and AFP > 20 ng/mL, n = 18). No-risk group had comparable disease-free survival (p = 0.269) and overall survival (p = 0.215) to patients who met the Milan criteria.

CONCLUSION

Patients with TTV ≤ 275 cm3 and AFP ≤ 20 ng/mL can have good outcomes even exceed the Milan criteria.

Racial/Ethnic Disparities and Immunotherapeutic Advances in the Treatment of Hepatocellular Carcinoma

Hepatocellular carcinoma (HCC) remains one of the leading causes of death among many associated liver diseases. Various conventional strategies have been utilized for treatment, ranging from invasive surgeries and liver transplants to radiation therapy, but fail due to advanced disease progression, late screening/staging, and the various etiologies of HCC. This is especially evident within racially distinct populations, where incidence rates are higher and treatment outcomes are worse for racial/ethnic minorities than their Caucasian counterparts. However, with the rapid development of genetic engineering and molecular and synthetic biology, many novel strategies have presented promising results and have provided potential treatment options. In this review, we summarize past treatments, how they have shaped current treatments, and potential treatment strategies for HCC that may prove more effective in the future.

Safety and Preliminary Efficacy of Pembrolizumab Following Transarterial Chemoembolization for Hepatocellular Carcinoma: The PETAL Phase Ib Study

PURPOSE

Transarterial chemoembolization (TACE) may prime adaptive immunity and enhance immunotherapy efficacy. PETAL evaluated safety, preliminary activity of TACE plus pembrolizumab and explored mechanisms of efficacy.

PATIENTS AND METHODS

Patients with liver-confined hepatocellular carcinoma (HCC) were planned to receive up to two rounds of TACE followed by pembrolizumab 200 mg every 21 days commencing 30 days post-TACE until disease progression or unacceptable toxicity for up to 1 year. Primary endpoint was safety, with assessment window of 21 days from pembrolizumab initiation. Secondary endpoints included progression-free survival (PFS) and evaluation of tumor and host determinants of response.

RESULTS

Fifteen patients were included in the safety and efficacy population: 73% had nonviral cirrhosis; median age was 72 years. Child-Pugh class was A in 14 patients. Median tumor size was 4 cm. Ten patients (67%) received pembrolizumab after one TACE; 5 patients after two (33%). Pembrolizumab yielded no synergistic toxicity nor dose-limiting toxicities post-TACE. Treatment-related adverse events occurred in 93% of patients, most commonly skin rash (40%), fatigue, and diarrhea (27%). After a median follow-up of 38.5 months, objective response rate 12 weeks post-TACE was 53%. PFS rate at 12 weeks was 93% and median PFS was 8.95 months [95% confidence interval (CI): 7.30-NE (not estimable)]. Median duration of response was 7.3 months (95% CI: 6.3-8.3). Median overall survival was 33.5 months (95% CI: 11.6-NE). Dynamic changes in peripheral T-cell subsets, circulating tumor DNA, serum metabolites, and in stool bacterial profiles highlight potential mechanisms of action of multimodal therapy.

CONCLUSIONS

TACE plus pembrolizumab was tolerable with no evidence of synergistic toxicity, encouraging further clinical development of immunotherapy alongside TACE.

Unaddressed regulatory issues in xenotransplantation: a hypothetical example

The last few years have seen a significant increase in the use of technology to manipulate genetic sequences and generate animals as a source of xeno-organs. This has made the generation of genetically bespoke organisms a reality. This paper will analyze the regulatory and practical aspects of such an innovative approach to xenotransplantation on the basis of a hypothetical case study applied to Germany and highlight the gaps in the current regulation. This paper thus provides the basis for legal debate within a specific country. In addition, the identified gaps also pose a barrier toward the harmonization of international regulation. This publication therefore lays the groundwork for guiding the international debate regarding the regulatory framework for solid organ xenotransplantation toward specific issues.

Egyptian Society of Liver Cancer Recommendation Guidelines for the Management of Hepatocellular Carcinoma

Globally, hepatocellular carcinoma (HCC) is the fourth most common cause of death from cancer. The prevalence of this pathology, which has been on the rise in the last 30 years, has been predicted to continue increasing. HCC is the most common cause of cancer-related morbidity and mortality in Egypt and is also the most common cancer in males. Chronic liver diseases, including chronic hepatitis C, which is a primary health concern in Egypt, are considered major risk factors for HCC. However, HCC surveillance is recommended for patients with chronic hepatitis B virus (HBV) and liver cirrhosis; those above 40 with HBV but without cirrhosis; individuals with hepatitis D co-infection or a family history of HCC; and Nonalcoholic fatty liver disease (NAFLD) patients exhibiting significant fibrosis or cirrhosis. Several international guidelines aid physicians in the management of HCC. However, the availability and cost of diagnostic modalities and treatment options vary from one country to another. Therefore, the current guidelines aim to standardize the management of HCC in Egypt. The recommendations presented in this report represent the current management strategy at HCC treatment centers in Egypt. Recommendations were developed by an expert panel consisting of hepatologists, oncologists, gastroenterologists, surgeons, pathologists, and radiologists working under the umbrella of the Egyptian Society of Liver Cancer. The recommendations, which are based on the currently available local diagnostic aids and treatments in the country, include recommendations for future prospects.

Evaluating the benefit of surgical resection for hepatocellular carcinoma with multifocality or intrahepatic vascular invasion

BACKGROUND

The role of hepatectomy for hepatocellular carcinoma (HCC) with multifocality or intrahepatic vascular involvement remains ill-defined. Our objective was to evaluate benefits of surgical resection for patients with these high-risk features.

METHODS

The National Cancer Database was used to identify HCC patients with vascular involvement and/or multifocality (T2/T3, N-/M-) from 2011 to 2015. Propensity score matching (k-nearest neighbors, no replacement, 1:1) grouped patients by treatment: surgical resection versus non-surgical modalities. Groups were matched using patient, clinical, and liver-specific characteristics. Median overall survival (OS) was calculated using Kaplan-Meier, and adjusted analyses were performed using shared frailty models.

RESULTS

14,557 patients met inclusion criteria, including 1892 (9.4%) treated with surgical resection. Median cohort OS was 20.5 months. After adjustment, surgical resection was associated with survival advantage compared to non-surgical treatment (37.8 versus 15.7 months, log-rank P < .001; adjusted hazard ratio 0.49, 95% confidence interval, 0.45-0.54). Patients with minimal comorbidity, unifocal disease, and age <54 had highest probability of survival one year post-surgery.

CONCLUSIONS

Surgical resection is associated with a survival advantage in HCC with multifocality and/or intrahepatic vascular involvement. The presence of these features should not contraindicate consideration of hepatectomy in suitable surgical candidates.

Comparison of CalliSpheres® microspheres drug-eluting beads and conventional transarterial chemoembolization in hepatocellular carcinoma patients: a randomized controlled trial

BACKGROUND

This trial aimed to compare the outcomes of drug-eluting beads transarterial chemoembolization (DEB-TACE) with CalliSpheres^® microspheres (CSM) and conventional transarterial chemoembolization cTACE in the treatment of patients with unresectable hepatocellular carcinoma (HCC).

PATIENTS AND METHODS

A total of 90 patients were divided into DEB-TACE group (n = 45) and cTACE group (n = 45). The treatment response, overall survival (OS), progression-free survival (PFS), and the safety were compared between the two groups.

RESULTS

The objective response rate (ORR) in the DEB-TACE group was significantly higher than that in cTACE group at 1, 3, and 6 months of follow-up (P = 0.031, P = 0.003, P = 0.002). The complete response (CR) in DEB-TACE group was significantly higher than that in cTACE group at 3 months (P = 0.036). Survival analysis revealed that, DEB-TACE group had better survival benefits than cTACE group (median OS: 534 days vs. 367 days, P = 0.027; median PFS: 352 days vs. 278 days P = 0.004). The degree of liver function injury was more serious in DEB-TACE group at 1 week, but was similar between the two groups at 1 month. DEB-TACE with CSM caused a high incidence of fever and a severe abdominal pain (P = 0.031, P = 0.037).

CONCLUSIONS

DEB-TACE with CSM showed better treatment response and survival benefits than cTACE group. Although a transient more severe liver damage, high incidence of fever and a severe abdominal pain occurred in the DEB-TACE group, it could be resolved through symptomatic treatment.

Investigating Up-to-Seven Criteria and APRI (AST Platelet Ratio) as Prognostic Factors in Intermediate-Stage Hepatocellular Carcinoma Patients Who Received Transarterial Chemoembolization

BACKGROUND

Transarterial chemoembolization (TACE) is one of the locoregional treatments for intermediate-stage hepatocellular carcinoma (HCC). Multidetector computed tomography (MDCT) is a widely used diagnostic tool for HCC. It can also evaluate tumor size, tumor number, and tumor invasion. This study aimed to determine the median survival time in intermediate-stage HCC patients who underwent TACE and to find out  prognostic factors influencing patients' survival time after TACE.

METHODS

A computerized search of medical record database in Maharaj Nakorn ChiangMai Hospital from January 2016 to December 2019 revealed 187 intermediate-stage HCC patients who received TACE as the first-line treatment.

RESULTS

The median survival time of patients in this study was 9.9 months (95% CI: 8.3-11.6). The patients with aspartate aminotransferase-to-platelet ratio (APRI) less than 0.5 had a significantly better median survival time as compared with patients with APRI ratio more than 0.5; (13.2 months versus 9.9 months, p-value < 0.05). Univariate and multivariate Cox regression analysis demonstrated that tumor number > 7 and tumor size > 5 centimeters (cm) could be considered as independent parameters predicting poor overall survival time in the sufferers (HR 2.64 95%CI 1.68-4.15 and HR 2.38 95%CI 1.32-4.31, respectively).

CONCLUSION

Based on our findings, patients with intermediate-stage HCC who received TACE had a lower median survival time compared to previous studies. However, we identified APRI less than 0.5, tumor size less than 5 cm, and tumor number less than 7 as prognostic factors improving survival time in intermediate-stage HCC patients.

Antiviral Therapy Improves Survival in Hepatocellular Carcinoma with Microvascular Invasion: A Propensity Score Analysis

BACKGROUND AND AIMS

To investigate the effect of postoperative adjuvant antiviral therapy (AVT) on hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) with microvascular invasion (MVI) after R0 liver resection.

METHODS

A total of 1008 patients with HBV-related HCC with MVI were recruited, which comprises 378 non-AVT groups and 630 AVT groups. Propensity score matching (PSM) was developed to reduce any bias in patient selection. Independent risk factors were identified by Cox regression analysis.

RESULTS

After PSM, the 1-, 3-, and 5-year overall survival rates in the AVT group and non-AVT group were 89.2%, 62.4%, 42.1%, and 73.3%, 46.3%, 22.1%, (p < 0.01), respectively. The 1-, 3-, and 5-year recurrence-free survival rates in the AVT group and non-AVT group were 52.5%, 30.4%, 22.1%, and 46.3%, 26.8%, 13.2% (p = 0.02), respectively. Multivariate Cox analysis revealed that postoperative adjuvant AVT was the independent protective factor associated with mortality (HR = 0.55, 95%CI = 0.46-0.67, p < 0.01) and tumor recurrence (HR = 0.81, 95%CI = 0.69-0.96, p = 0.01).

CONCLUSIONS

Among patients who underwent curative hepatectomy for HBV-related HCC with MVI, postoperative adjuvant AVT was the independent protective factor associated with mortality and tumor recurrence. Given the high rate of postoperative recurrence and poor prognosis of HBV-related HCC with MVI, our findings may have useful clinical significance in the prevention of tumor recurrence in these patients.

Radiofrequency ablation vs radiation therapy vs transarterial chemoembolization vs yttrium 90 for local treatment of liver cancer - a systematic review and network meta-analysis of survival data

INTRODUCTION

The comparative effectiveness of radiofrequency ablation (RFA), radiation therapy (RT), transarterial chemoembolization (TACE) and transarterial radioembolization with Yttrium-90 (Y90) relative to one another for the treatment of hepatocellular carcinoma (HCC) is unclear. The aim of this systematic review and network meta-analysis is to compare RFA to RT to TACE to Y90 in the treatment of HCC.

METHODS

Pubmed, Embase and Cochrane CENTRAL were searched up until April 19, 2021. Observational analyses with propensity score matched (PSM) cohort analyses and randomized controlled trials (RCT) reporting on two or more treatments relative to one another with respect to overall survival (OS) and/or progression free survival (PFS) were included. Survival data were extracted from Kaplan-Meier survival curves, and meta-analyzed using a multivariate network meta-analysis.

RESULTS

After exclusions, 24 RCTs or PSM observational studies reporting on 5549 patients were included. While 1-year OS was greater for Y90 than TACE (RR 0.85, 95% CI: 0.72-0.99), all other 1-year OS comparisons across the 4 modalities yielded similar OS, and there were no differences across any modalities in 2-year and 3-year OS. TACE had a modest PFS advantage relative to RFA (RR 0.81, 95% CI: 0.68-0.95) and RT (RR 0.65, 95% CI: 0.51-0.83) at 2 years.

CONCLUSION

All modalities assessed resulted in similar OS, which explains the current heterogenous practice patterns. This conclusion may assist in decision making based on administrative and patient costs, and implementation of these modalities. Other factors such as toxicity rate specific to individual patients could not be assessed using network meta-analysis and may also play a role in selection of modality. Further studies, ideally using PSM cohort analyses or RCT study design, reporting on OS, PFS, local control, complete response and toxicity are needed prior to drawing definitive conclusions.

Ramucirumab for Patients with Intermediate-Stage Hepatocellular Carcinoma and Elevated Alpha-Fetoprotein: Pooled Results from Two Phase 3 Studies (REACH and REACH-2)

BACKGROUND

Intermediate-stage hepatocellular carcinoma (HCC), as defined by Barcelona Clinic Liver Cancer (BCLC) stage B, is heterogeneous in terms of liver function and tumor burden. REACH and REACH-2 investigated ramucirumab in patients with HCC after prior sorafenib, with REACH-2 enrolling only patients with baseline α-fetoprotein (AFP) ≥400 ng/mL. An exploratory analysis of outcomes by BCLC stage was performed.

METHODS

A pooled meta-analysis of independent patient data (stratified by study) from REACH (AFP ≥ 400 ng/mL) and REACH-2 was performed. All patients had Child-Pugh A, Eastern Cooperative Oncology Group performance status 0-1, prior sorafenib treatment, and either HCC BCLC stage B (refractory/not amenable to locoregional therapy) or BCLC stage C. Patients were randomized to ramucirumab 8 mg/kg or placebo every 2 weeks. Median overall survival (OS) and progression-free survival were estimated by the Kaplan-Meier method. Treatment effects in BCLC stage B and C were evaluated by Cox proportional-hazards model; prognosis of BCLC staging for OS was evaluated by multivariate Cox proportional-hazards model. Tumor responses were evaluated according to Response Evaluation in Solid Tumors v1.1. Liver function was assessed with albumin-bilirubin score.

RESULTS

Baseline characteristics were generally balanced between treatment arms in each BCLC stage. BCLC staging trended as an independent prognostic factor for OS (B vs. C; hazard ratio [HR] 0.756 [95% CI 0.546-1.046]). Consistent treatment benefit was observed for ramucirumab versus placebo across BCLC stages. Median OS for ramucirumab versus placebo was 13.7 versus 8.2 months; HR (95%): 0.43 (0.23-0.83) and 7.7 versus 4.8 months; HR (95%): 0.72 (0.59-0.89) for BCLC stage B and C, respectively. Adverse events (AEs) were consistent with observations from both studies; hypertension was the most frequent grade ≥3 AE. Liver function was preserved throughout the study and similar between treatment arms in both BCLC stages.

CONCLUSIONS

Ramucirumab provided a better survival benefit irrespective of BCLC stage and was well tolerated without compromising liver function during treatment.

Incorporating albumin-bilirubin grade and up-to-seven criteria to predict outcomes of patients with intermediate stage hepatocellular carcinoma after transarterial (chemo)embolization

BACKGROUND/PURPOSE

This study is to use albumin-bilirubin (ALBI) grade and up-to-7 (UT7) criteria to assess outcomes of patients with intermediate stage hepatocellular carcinoma (HCC) after transarterial (chemo)embolization (TA(C)E).

METHODS

Between January 2012 and January 2019, newly diagnosed intermediate HCC patients underwent TA(C)E were enrolled and analyzed. The demographics, clinical characteristics and survival were obtained from medical chart reviews.

RESULTS

A total of 359 patients were enrolled and 30.4% of them were within UT7 criteria (UT7 (-)). There were 36.5%, 59.3%, and 4.2% of the patients with ALBI grade I, II, and III, respectively. Beyond UT7 (UT7 (+)) and ALBI grade II/III were associated with overall mortality in multivariate analysis. Based on ALBI grade I/II/III and UT7 -/+, patients were classified into six groups as ALBI grade I plus UT7 (-), II plus UT7 (-), III plus UT7 (-), I plus UT7 (+), II plus UT7 (+), and III plus UT7(+). Distributions of median survival were 47.5, 32.9, 15, 34.3, 16.7 and 14.3 months, respectively. Patients with statistically insignificant survivals were further combined. Patients with ALBI grade I plus UT7 (-) were reclassified as ALBI-U class I, whereas ALBI grade II plus UT7 (-) and I plus UT7 (+) were ALBI-U class II, and the others were ALBI-U class III. There were 8.4%, 48.7%, and 42.9% of patients in ALBI-U class I, II, and III, respectively. The 5-year survival rate was 48.8%, 22.5%, and 13.7% in ALBI-U class I, II, and III, respectively (p < 0.01).

CONCLUSION

ALBI-U classification was useful in predicting outcomes of patient with intermediate stage HCC after TA(C)E.

Role of modern radiotherapy in managing patients with hepatocellular carcinoma

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. Several treatment options are available for managing HCC patients, classified roughly as local, local-regional, and systemic therapies. The high post-monotherapy recurrence rate of HCC urges the need for the use of combined modalities to increase tumor control and patient survival. Different international guidelines offer treatment recommendations based on different points of view and classification systems. Radiotherapy (RT) is a well-known local-regional treatment modality for managing many types of cancers, including HCC. However, only some of these treatment guidelines include RT, and the role of combined modalities is rarely mentioned. Hence, the present study reviewed clinical evidence for the use of different combined modalities in managing HCC, focusing on modern RT's role. Modern RT has an increased utility in managing HCC patients, mainly due to two driving forces. First, technological advancement (e.g., stereotactic body radiotherapy and advanced proton-beam therapy) enables precise delivery of radiation to increase tumor control and reduce side effects in the surrounding normal tissue. Second, the boom in developing target therapies and checkpoint-blockade immunotherapy prolongs overall survival in HCC patients, re-emphasizing the importance of local tumor control. Remarkably, RT combines with systemic therapies to generate the systemic therapy augmented by radiotherapy effect, a benefit now being actively investigated.

Comparing the diagnostic value of serum oligosaccharide chain (G-test) and alpha-fetoprotein for hepatitis B virus-related liver cancer

OBJECTIVES

The study compared the diagnostic efficiency of serum oligosaccharide chain (G-test) and alpha-fetoprotein (AFP) for hepatitis B-related hepatocellular carcinoma (HCC).

METHODS

Serum samples from 100 patients (divided into five groups of 20 each, namely the hepatitis, liver cirrhosis, liver cancer, health, and interference groups) who were admitted to the Second Affiliated Hospital of Nanchang University from October 2019 to January 2020 were collected, and the levels of G-test and AFP were determined. The sensitivity and specificity of the two indicators were compared, and the receiver operating characteristic curve of the subjects was drawn to evaluate the diagnostic values of G-test and AFP for HCC.

RESULTS

The diagnostic ability of G-test (area under the curve [AUC]: 0.88 ± 0.05) was better than that of AFP (AUC: 0.76 ± 0.05). When G-test and AFP were combined for detection, the AUC was larger than that of either indicator. The G-test was superior to AFP in the differential diagnosis of early HCC and cirrhosis. A combination of the two indicators (AUC: 0.769 ± 0.05) significantly improved the diagnostic rate for early HCC, indicating that G-test and AFP complemented each other.

CONCLUSION

G-test was better than AFP for screening HCC in patients with chronic hepatitis B and cirrhosis. The combination of the two further improved the diagnostic rate of hepatitis B-related liver cancer. The G-test improves the screening rate of early HCC in patients with cirrhosis. Therefore, these markers are of great clinical significance and can improve the sensitivity of HCC detection and reduce missed diagnosis rates.

Transarterial Chemoembolization Combined With Hepatectomy for the Treatment of Intermediate-Stage Hepatocellular Carcinoma

Background

Transarterial chemoembolization (TACE) is currently the recommended treatment for intermediate-stage hepatocellular carcinoma (HCC). Liver resection (LR) may be an effective option, although recurrences are not uncommon. TACE prior to LR has been proposed as an even better alternative.

Methods

Patients with intermediate-stage HCC who underwent curative resection were enrolled between January 2007 and December 2015. We compared overall survival (OS) and recurrence-free survival (RFS) for the 2 groups using the Kaplan-Meier method, and we determined independent risk factors for death and recurrence using multivariate regression analyses.

Results

A total of 488 patients with HCC at BCLC B (265 patients with LR, 223 patients with TACE+LR) enrolled from our center. Mean follow-up was 40.2 (range, 3.0-128.7) months. For patients receiving TACE+LR and LR, estimated 1-, 3-, and 5-year OS rates were 90.6% and 73.3%, 61.7% and 43.5%, and 52.9% and 33.8%, respectively (all P < 0.001) and estimated 1-, 2-, and 3-year RFS rates were 54.6% and 39.4%, 41.4% and 29.4%, and 36.3% and 26.3%, respectively (P < 0.001, P = 0.002, and P = 0.008, respectively). Significant independent predictors of poor OS were more than 3 (vs. 3 or fewer) tumors (HR=2.19, 95% CI 1.69-2.84), non-anatomical (vs. anatomical) hepatectomy (HR=1.29, 95% CI 1.01-1.66), microscopic vascular invasion (HR=1.46, 95% CI 1.15-.90), cirrhosis (HR=2.41, 95%CI 1.88-3.01), and intraoperative blood transfusion (HR=1.29, 95% CI 1.01-1.66).

Conclusion

Preoperative TACE with LR may result in better oncological outcomes than either TACE or LR alone, without a substantial increase in morbidity, and could be considered an effective combination treatment for intermediate-stage HCC.

Drug-eluting Bead-Transcatheter Arterial Chemoembolization for Advanced Hepatocellular Carcinoma Refractory to Conventional Lipiodol-based Transcatheter Arterial Chemoembolization

Purpose

To evaluate the potential of drug-eluting bead (DEB)-transcatheter arterial chemoembolization (TACE) as a treatment option for patients with refractory to conventional lipiodol-based TACE (c-TACE) especially with decreased liver function.

Patients and Methods

We retrospectively evaluated the treatment results of DEB-TACE for 89 HCC nodules in 27 patients with c-TACE refractory according to liver function.

Results

Although overall survival was significantly better in Child–Pugh A patients than in Child–Pugh B patients (median survival time, MST: 561 vs 347 days, p=0.031), progression-free survival was almost similar in both patients between Child–Pugh A and B (MST: 79 vs 87 days, p=0.534). Regarding antitumor response, the objective response rate (ORR) and disease-control rate (DCR) were 5.3/12.5% and 52.7/87.5% in Child–Pugh A/B, respectively. In each 89 HCC nodules, ORR and DCR were almost similar between Child–Pugh A and B (ORR, 20.3 vs 13.3%; DCR, 77.0 vs 73.3%, respectively). Adverse events of DEB-TACE were well-tolerated, and liver function was reserved during DEB-TACE procedures.

Conclusion

DEB-TACE could be a therapeutic option for advanced HCC patients with c-TACE refractory and decreased liver function.

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.

Preoperative antiviral therapy and microvascular invasion in hepatitis B virus-related hepatocellular carcinoma: A meta-analysis

Microvascular invasion (MVI) is an important predictor of metastatic tumour recurrence and is associated with adverse outcomes and poor prognosis in Hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) patients. The association between varying regimens of anti-viral drugs with the incidence of MVI in HBV-related HCC has been demonstrated, however, no meta-analysis of the available data has been conducted. Therefore, the current study sought to evaluate the association of preoperative antiviral therapy with incidence of microvascular invasion in HCC hepatitis virus patients. A systematic search of the literature was performed in MEDLINE/PubMed, Web of Science (WoS), and Scopus, up to January 2020. A random-effects model was used to estimate pooled odds ratios (ORs). Overall, six studies, with 4988 patients, met our inclusion criteria. The pooled OR of MVI in the patients who had preoperative antiviral therapy versus the patients who did not have antiviral therapy was; OR: 0.60, 95% Confidence Interval (CI): 0.49-0.73; I² = 25%. In this study, a significant reduction in the OR of MVI was evident in patients who had anti-viral therapy.

A novel multitarget kinase inhibitor BZG with potent anticancer activity in vitro and vivo enhances efficacy of sorafenib through PI3K pathways in hepatocellular carcinoma cells

OBJECTIVES

BZG as a novel multitarget kinase inhibitor, has been proved to inhibit the proliferation of hepatocellular carcinoma (HCC) previously. In this study, we aimed at investigating the underlying mechanisms of BZG with and without sorafenib and evaluating their anti-tumor effects as well as whether BZG could inhibit the activation of phosphoinositide 3-kinase (PI3K)/AKT signaling which is associated with acquired resistance to sorafenib.

METHODS

We evaluated the proliferation of HCC cells by CCK-8 assay and colony formation assay. Cell apoptosis was assessed by Hoechst 33342 staining assay and flow cytometry. Western blot was used to detect the critical enzymes in the PI3K pathways and the expression of p-ERK after BZG alone and combined with sorafenib treatments. Huh-7 hepatocellular carcinoma xenograft model was used to evaluate the anti-carcinoma effects of BZG alone and in combination in vivo. HE staining and TUNEL assay tested the necrosis of tumor tissue and apoptosis of tumor cells.

RESULTS

BZG could inhibit the proliferation of HCC cells in a dose-dependent manner. The combination of BZG and sorafenib produced synergistic effects. PI3K and p-ERK pathway were involved in the anti-tumor functions of BZG alone and when combined with sorafenib. In addition, the combination treatment was seen to be more effective in inhibiting the expression of p-AKT, p-ERK and p-mTOR. Furthermore, Tumor necrosis and cell apoptosis were also observed in Huh-7 hepatocellular carcinoma xenograft models.

CONCLUSIONS

BZG is an attractive agent for treating HCC. The effects of BZG and sorafenib's co-treatment on HCC are more effective than BZG or sorafenib alone.

Increased Level of Systolic Blood Pressure in Hepatocellular Carcinoma Patients with Diabetes Mellitus

BACKGROUND

More than 50% of patients with type 2 diabetes mellitus (DM) also have hypertension. Moreover, hypertension has been regarded as one paraneoplastic phenomenon of hepatocellular carcinoma (HCC). Our study was designed to determine the relationship between blood pressure and DM in HCC patients.

PATIENTS AND METHODS

A total of 879 HCC patients were included and 151 (17.2%) were diagnosed with DM. Multivariable logistic regression analysis was used to determine the relationship and the results were expressed as adjusted odds ratios (AORs) and their 95% confidence intervals (CIs). Considering the effect of potential confounders, sub-group analysis was performed. We would further study the association of systolic blood pressure (SBP) with fasting glucose, and the association between DM duration/treatment and SBP level.

RESULTS

Compared with non-diabetic patients, the diabetic patients had increased levels of SBP (133.7±18.5 mmHg vs 128.3±15.2 mmHg, P=0.001) and fasting blood glucose (9.13±3.04 mmol/L vs 5.18±1.08 mmol/L, P<0.001), an elder age (58.5±10.2 years vs 55.3±11.2 years, P=0.001), a higher percentage of cirrhosis diagnosis (60.9% vs 48.2%, P=0.004), lower percentages of drinking (18.5% vs 30.8%, P=0.002) and smoking (30.5% vs 43.7%, P=0.003), and decreased levels of GGT (median/interquartile-range 88/53-177 U/L vs 117/58-248 U/L, P=0.037), platelet count (121.4±76.6 ×10⁹/L vs 151.2±82.8 ×10⁹/L, P<0.001) and hemoglobin (124.3±25.5 g/L vs 133.6±24.2 g/L, P<0.001). Multivariable analysis showed that, statistically significant differences were found for SBP ≥140 mmHg (AOR=2.101; 95% CI, 1.424-3.100; P<0.001), smoking (AOR=0.637; 95% CI, 0.415-0.979; P=0.040), hemoglobin (AOR=0.990; 95% CI, 0.983-0.998; P=0.010) and platelet count (AOR=0.996; 95% CI, 0.994-0.999; P=0.009). For the relationship between SBP and DM, the positive result was supported by most (10/14) of the subgroup analyses.

CONCLUSION

SBP level was increased in HCC patients with diabetes mellitus.
