Comparative application of MAFLD and MASLD diagnostic criteria on NAFLD patients: insights from a single-center cohort

The diagnostic criteria for Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD) and Metabolic Associated Steatotic Liver Disease (MASLD) aim to refine the classification of fatty liver diseases previously grouped under Non-Alcoholic Fatty Liver Disease (NAFLD). This study evaluates the applicability of the MAFLD and MASLD frameworks in NAFLD patients, exploring their clinical utility in identifying high-risk patients. A total of 369 NAFLD patients were assessed using MAFLD and MASLD diagnostic criteria. Baseline characteristics, metabolic profiles, hepatic fibrosis, and cardiovascular risks were compared across the groups. Among NAFLD patients, 97.55% (n = 359) met MASLD criteria, and 97.01% (n = 357) fulfilled MAFLD criteria. Both frameworks MAFLD and MASLD captured overlapping populations, with MASLD encompassing slightly more cases. No significant differences were observed in metabolic risk factors, fibrosis indices (APRI, FIB-4, NAFLD fibrosis score), or cardiovascular risk (10-year ASCVD score). A small subset of lean NAFLD patients (10 cases) with distinct profiles remained uncategorized by either framework. Pure NAFLD cases (n = 10) were with mild insulin resistance (HOMA-IR: 3.07 ± 0.33) and slightly elevated LDL (102.5 ± 42.87 mg/dL), while fibrosis indices indicated low fibrosis risk. Steatosis indices supported the diagnosis of early-stage NAFLD with preserved liver function. These patients do not meet the criteria for inclusion in the MAFLD or MASLD frameworks, highlighting a gap in the current diagnostic systems. MAFLD and MASLD criteria align closely with NAFLD in capturing patients with metabolic risk with MASLD-enhanced inclusivity. Further refinement is required to address heterogeneity, particularly in lean NAFLD patients. Hypertension prevalence was comparable (17.4% in NAFLD, 18.2% in MAFLD, 17.8% in MASLD; p = 0.960), as was diabetes mellitus (36.7%, 37.8%, and 37.6%, respectively; p = 0.945). Body mass index was also similar across groups, with medians of 33.25, 33.6, and 33.4 kg/m2 (p = 0.731). Non-invasive markers of hepatic fibrosis, including APRI, FIB-4, and NAFLD fibrosis scores, did not differ significantly, with median FIB-4 scores around 1.05 (p = 0.953). Similarly, were the results of hepatic steatosis index and ASCVD score.

In Vitro Evaluation of Probiotic Activities and Anti-Obesity Effects of Enterococcus faecalis EF-1 in Mice Fed a High-Fat Diet.

This research sought to assess the anti-obesity potential of Enterococcus faecalis EF-1. An extensive and robust in vitro methodology confirmed EF-1's significant potential in combating obesity, probably due to its excellent gastrointestinal tract adaptability, cholesterol-lowering property, bile salt hydrolase activity, α-glucosidase inhibition, and fatty acid absorption ability. Moreover, EF-1 exhibited antimicrobial activity against several pathogenic strains, lacked hemolytic activity, and was sensitive to all antibiotics tested. To further investigate EF-1's anti-obesity properties in vivo, a high-fat diet (HFD) was used to induce obesity in C57BL/6J mice. Treatment with EF-1 (2 × 109 CFU/day) mitigated HFD-induced body weight gain, reduced adipose tissue weight, and preserved liver function. EF-1 also ameliorated obesity-associated microbiota imbalances, such as decreasing the Firmicutes/Bacteroidetes ratio and boosting the levels of bacteria (Faecalibacterium, Mucispirillum, Desulfovibrio, Bacteroides, and Lachnospiraceae_NK4A136_group), which are responsible for the generation of short-chain fatty acids (SCFAs). Concurrently, the levels of total SCFAs were elevated. Thus, following comprehensive safety and efficacy assessments in vitro and in vivo, our results demonstrate that E. faecalis EF-1 inhibits HFD-induced obesity through the regulation of gut microbiota and enhancing SCFA production. This strain appears to be a highly promising candidate for anti-obesity therapeutics or functional foods.

Доклиническое исследование визуализационных свойств комплекса Mn(II)–D-мио-инозитол-1, 2, 3, 4, 5, 6-гексакисдигидрофосфорная кислота как гепатоспецифичного парамагнитного контрастного соединения

Purpose: We tried to create a hepatospecific paramagnetic contrast agent – a paramagnetic analogue of 99mTc-technefit, by obtaining a paramagnetic Mn(II) complex with phytic (D-myo-inositol-1, 2, 3, 4, 5, 6– hexakisdihydrophosphoric) acid. Material and methods: A hepatotropic magnetic resonance contrast compound was obtained as an aqueous solution containing a paramagnetic Mn(II) complex with D-myo-inositol-1, 2, 3, 4, 5, 6-hexakis dihydrophosphoric (phytic) acid in a concentration of 0.5 M, with the addition of a 0.5M aqueous solution of meglumine (N-methylglucamine) in a ratio of 1:4 by volume to maintain pH in the range of 6.2–7.8, as well as to improve the stability of the solution. The working name of the Mn(II) complex with phytic acid phytomang®. The toxicological properties of the compound were evaluated when administered to laboratory mice, R1 relaxation and imaging properties in Wistar laboratory rats weighing 350-400 g, using low-field (field strength 0.2 T) and high-field (field strength 1.5 T) MR tomographs. Results: For 0.5 M of an aqueous solution of Mn-phytate, with the addition of meglumine, LD50, when administered acutely to laboratory animals – mice, is more than 18.7 ml / kg of body weight, which allows this compound to be classified according to GOST 12.1.007-76 standards to group 4 – low-hazard substances. The thermodynamic stability constant was 17.5. Spin-lattice relaxivity R1 in aqueous solution at a field strength of 0.2T: R1 = 6.82 1/ms. After intravenous administration to healthy rats with preserved liver function, Mn-phytate is distributed in the bloodstream, with rapid absorption within 5 minutes by liver tissue, followed by partial (up to 7 ± 3 % of the dose) excretion into bile after 30 minutes or more. The total uptake of the drug by the liver is 72 ± 7 % of the administered dose. Conclusion: The complex compound Mn (II) with D-myo-inositol-1, 2, 3, 4, 5, 6– hexakis dihydrophosphoric (phytic) acid belongs to low-toxic substances, is stable in aqueous media and has a high relaxability R1, selectively accumulates and intensively contrasts the liver parenchyma, and can be considered as the basis for creating a hepatospecific paramagnetic contrast preparation for use in MRI diagnostics liver in experimental and clinical studies.

Effectiveness of sorafenib in treating intermediate-stage hepatocellular carcinoma patients refractory to transarterial chemoembolization

BackgroundSwitching to systemic therapy after transarterial chemoembolization (TACE) refractoriness is more inclined to preserve liver function and decrease disease progression. Hence, we conducted a comparison between the advantages of sorafenib therapy and the continuation of TACE in patients with intermediate-stage hepatocellular carcinoma (HCC) who developed TACE refractoriness.MethodsThis retrospective cohort work involved 1,200 patients with HCC who received TACE therapy at our institution between January 2018 and December 2022. Out of these, a total of 436 participants were determined to be resistant to TACE treatment throughout their clinical progression. Out of them, 271 were finally included and categorized into two groups: (1) patients who shifted from TACE to sorafenib, and (2) patients who maintained TACE treatment. The study assessed the overall survival (OS) and time to disease progression (TTDP) of patients who were resistant to TACE, comparing both groups based on when they achieved Child-Pugh C or acquired advanced-stage HCC.ResultsFollowing confirmation of refractoriness to TACE therapy, 163 opted to continue with TACE (TACE group), whereas 108 shifted to sorafenib treatment (sorafenib group). The median TTDP was 23.36 months, while the median OS was 25.3 months, in the sorafenib group, and 11.6 and 14.2 months, correspondingly, in the TACE group (p = 0.0001).ConclusionSwitching to sorafenib treatment significantly improved OS and TTDP in patients with intermediate-stage HCC who were refractory to TACE. These finding highlights sorafenib’s potential as an effective alternative for managing disease progression in patients unresponsive to TACE, offering a valuable treatment option in this challenging clinical scenario.

Atezolizumab/bevacizumab and lenvatinib for hepatocellular carcinoma: A comparative analysis in a European real-world cohort.

Immunotherapy-based combinations are currently the standard of care in the systemic treatment of patients with HCC. Recent studies have reported unexpectedly long survival with lenvatinib (LEN), supporting its use in first-line treatment for HCC. This study aims to compare the real-world effectiveness of LEN to atezolizumab/bevacizumab (AZ/BV). A retrospective analysis was conducted to evaluate the effectiveness and safety of frontline AZ/BV or LEN therapy in patients with advanced HCC across 18 university hospitals in Europe. The study included 412 patients (AZ/BV: n=207; LEN: n=205). Baseline characteristics were comparable between the 2 treatment groups. However, patients treated with AZ/BV had a significantly longer median progression-free survival compared to those receiving LEN. The risk of hepatic decompensation was significantly higher in patients with impaired baseline liver function (albumin-bilirubin [ALBI] grade 2) treated with AZ/BV compared to those with preserved liver function. Patients with alcohol-associated liver disease had poorer baseline liver function compared to other etiologies and exhibited a worse outcome under AZ/BV. In this real-world cohort, survival rates were similar between patients treated with LEN and those treated with AZ/BV, confirming that both are viable first-line options for HCC. The increased risk of hepatic decompensation in patients treated with AZ/BV who have impaired baseline liver function underscores the need for careful monitoring. Future trials should aim to distinguish more clearly between metabolic dysfunction-associated steatotic liver disease and alcohol-associated liver disease.

Comparative analysis of treatment modalities for solitary, small (≤3 cm) hepatocellular carcinoma: A systematic review and network meta-analysis of oncologic outcomes

BackgroundSolitary hepatocellular carcinoma measuring ≤3 cm represents approximately 30% of hepatocellular carcinoma cases, yet treatment guidelines lack robust evidence. This study compares oncologic outcomes after ablation, liver resection, and liver transplantation for solitary, small hepatocellular carcinoma. MethodsWe systematically searched databases up to 7 February 2022, for studies including adults with solitary hepatocellular carcinoma ≤3 cm treated by any ablation, liver resection, or liver transplantation. We excluded non-hepatocellular carcinoma cancers, recurrent/metastatic diseases, and alternative therapies. A frequentist network meta-analysis assessed 5-year overall survival and recurrence-free survival using only adjusted effect estimates while accounting for bias risk. ResultsWe identified 80 studies (4 randomized controlled trials, 72 retrospectives, and 4 prospective cohorts) with 28,211 patients. In the network meta-analysis for 5-year overall survival (26 studies), liver transplantation was associated with the lowest mortality hazard (hazard ratio, 0.47; 95% confidence interval, 0.31–0.73, referenced to liver resection), followed by liver resection (reference), whereas ablation had the greatest mortality hazard (hazard ratio, 1.32; 95% confidence interval, 1.16–1.49, referenced to liver resection). For 5-year recurrence-free survival (19 studies), liver transplantation had the best outcome (hazard ratio, 0.36; 95% confidence interval, 0.20–0.63, referenced to liver transplantation), followed by liver resection (reference), with ablation showing the least favorable outcome (hazard ratio, 1.67; 95% confidence interval, 1.45–1.93, referenced to liver resection). ConclusionsThis network meta-analysis provides the evidence for comparing treatment modality outcomes for solitary, small (≤3 cm) hepatocellular carcinoma. LT emerges as the superior choice for achieving a better 5-year OS, followed by liver resection, then ablation. When feasible to preserve liver function, liver resection can be prioritized. Ablation with close surveillance should be reserved for individuals unfit for surgery.

5-Fluorouracil combined with CalliSphere drug-eluting beads or conventional transarterial chemoembolization for unresectable hepatocellular carcinoma: a propensity score weighting analysis

This study aimed to assess the effectiveness and safety of 5-Fluorouracil (5-Fu) combined with conventional transarterial chemoembolization (cTACE) compared to 5-Fu combined with drug-eluting bead transarterial chemoembolization (DEB-TACE) using CalliSpheres for the treatment of unresectable hepatocellular carcinoma (HCC) using propensity score weighting methods. This retrospective analysis included 131 patients with HCC treated with 5-Fu combined with cTACE (5-Fu-cTACE group, n = 65) or DEB-TACE (5-Fu-DEB-TACE group, n = 66) at the Affiliated Hospital of North Sichuan Medical College from January 2019 to December 2022. Based on the baseline data and laboratory indicators, propensity score weighting was used to reduce confounding bias. Modified response evaluation criteria in solid tumors (mRECIST) were used to evaluate clinical efficacy. The primary endpoint was progression-free survival (PFS), and the secondary endpoints were the disease control rate (DCR), objective response rate (ORR) and adverse events (AEs). PFS was assessed using Kaplan‒Meier analysis and Cox proportional hazards models. The ORRs at 1 month (M1) after treatment in the 5-Fu-DEB-TACE group and 5-Fu-cTACE group were 90.9% and 76.9%, respectively (P = 0.029), while at this time, the DCRs were 93.9% in the 5-Fu-DEB-TACE group and 90.8% in the 5-Fu-cTACE group (P = 0.494). At 3 months (M3) after treatment, the 5-Fu-DEB-TACE group had a higher ORR (84.8% vs. 56.9%, P < 0.001) and DCR (84.8% vs. 72.3%, P = 0.08). The ORR at 6 months (M6) was also higher in the 5-Fu-DEB-TACE group than in the 5-Fu-cTACE group (72.7% vs. 50.8%, P = 0.01). The median PFS after treatment with 5-Fu-DEB-TACE was longer than that after treatment with 5-Fu-cTACE (11 months vs. 6 months) (P = 0.004). Cox proportional hazards regression analysis indicated that 5-Fu-DEB-TACE (HR = 0.590, P = 0.044), Model for End-Stage Liver Disease (MELD) intermediate risk (HR = 2.470, P = 0.010), BCLC stage B (HR = 2.303, P = 0.036), BCLC stage C (HR = 3.354, P = 0.002) and ascitic fluid (HR = 2.004, P = 0.046) were independent predictors of PFS. No treatment-related deaths occurred in this study. The 5-Fu-DEB-TACE group had a greater incidence of abdominal pain (72.7% vs. 47.7%, P = 0.003). However, the incidence of postoperative elevated transaminase levels was higher in the 5-Fu-cTACE group (83.1% vs. 66.6%, P = 0.031). Subgroups analysis showed patients receiving 5-Fu-DEB-TACE have better PFS compared to those receiving 5-Fu-cTACE in the BCLC stage A group (P = 0.0093), BCLC stage B group (P = 0.0096), multifocal group (P = 0.0056), Child-Pugh stage A group (P<0.001), non- extrahepatic metastasis group (P = 0.022), non-vascular invasion group (P = 0.0093), and the group with a largest tumor diameter ≥ 5 cm (P = 0.0048). At M1, M3, and M6, patients with preserved liver function and in some cases of low tumor burden had higher Objective Response Rate (ORR) and Disease Control Rate (DCR) (P < 0.05). Compared with 5-Fu-cTACE, 5-Fu-DEB-TACE has superior therapeutic efficacy, prolongs PFS, and reduces hepatotoxicity. However, it is associated with an increased incidence of postoperative abdominal pain.

Locoregional Therapies and Interventional Radiology in Managing Hepatocellular Carcinoma: A Comprehensive Approach to Bridging, Downstaging, and Liver Transplantation

AbstractHepatocellular carcinoma (HCC) remains a significant global health challenge, particularly for patients awaiting liver transplants (LTs) due to the scarcity of donor organs. During the waiting period, a multidisciplinary approach becomes crucial to optimize tumor treatment and preserve liver function. In recent years, interventional radiology has emerged as an integral part of treatment strategies. It has played a pivotal role in bridging and downstaging patients on the path to transplantation. Interventional radiologists administer minimally invasive locoregional therapies to HCC patients on LT waiting lists. Additionally, they address complications such as portal hypertension and portal vein thrombosis, which can lead to clinical deterioration and jeopardize transplant candidacy. This article examines the pivotal role of interventional radiology in the management of HCC, highlighting recent studies and advancements within the field. Additionally, it provides a concise review of the eligibility criteria for LT in patients with HCC, alongside a discussion of the surgical techniques employed in LT for these patients.

Laparoscopic central hepatectomy: Feasibility and safety.

Anatomical liver resection is the gold standard for hepatocellular carcinoma (HCC), enhancing survival and disease-free outcomes. For centrally located tumors, major resections are necessary but risky, especially for patients with liver disease. Central hepatectomy (CH) offers a parenchymal-sparing alternative to extended or hemihepatectomy (HH), reducing postoperative liver failure risk. However, its complexity and the large transection area make it challenging, especially with laparoscopic techniques. This study evaluates the feasibility and safety of laparoscopic CH for centrally located HCC, comparing surgical outcomes with those of the HH group. A total of 1592 laparoscopic hepatectomy cases from January 2011 to April 2023 were reviewed in a single institution. Patients undergoing laparoscopic CH were compared to those receiving HH during the same period. Exclusion criteria included non-HCC diagnosis, non-central tumors, and cases involving combined procedures. 70 cases of laparoscopic CH and 32 cases of laparoscopic HH were included. The CH and HH groups showed similar estimated blood loss (median 400ml vs. 290ml, p = 0.187) and intraoperative blood transfusion rates (10% vs. 15%, p = 0.413). Operation time did not significantly differ (median 330min vs. 360min, p = 0.862). Postoperative hospital stay was shorter in CH (median 6days vs. 9days, p = 0.018), with fewer ICU transfers (19% vs. 44%, p = 0.014) and lower 90-day mortality (1% vs. 9%, p = 0.055) compared to HH. Complication rates were similar overall (26% vs. 41%, p = 0.069), but HH had more Clavien-Dindo class I and II complications (13% vs. 19%, p = 0.040). Long-term survival did not significantly differ, but tended to favor the CH group. Despite the complexity, laparoscopic CH offers comparable perioperative outcomes and favorable long-term survival compared to HH. It can be considered a viable option for centrally located HCC, preserving liver function.

Small particle drug-eluting beads-transarterial chemoembolization combined with targeted therapy in the clinical treatment of unresectable liver cancer.

Liver cancer is a highly malignant tumor with significant clinical impact. Chemotherapy alone often yields suboptimal outcomes in both the short and long term, characterized by high rates of local recurrence and distant metastasis, leading to a poor long-term prognosis. To evaluate the clinical efficacy of small particle drug-eluting beads-transarterial chemoembolization (DEB-TACE) combined with targeted therapy for the treatment of unresectable liver cancer. We analyzed clinical data from 74 patients with unresectable liver cancer admitted between January 2019 and December 2020. Based on the different treatment regimens administered, patients were divided into the control (36 patients receiving sorafenib alone) and joint (38 patients receiving small particle DEB-TACE combined with sorafenib) groups. We compared liver function indicators [alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), albumin (ALB)] and serum tumor markers [alpha fetoprotein (AFP)] before and after treatment in both groups. Short-term efficacy measures [complete response (CR), partial response, progression disease, stable disease, objective response rate (ORR), and disease control rate (DCR)] were assessed post-treatment. Long-term follow-up evaluated median overall survival (OS), progression-free survival (PFS), and adverse reaction rates between the two groups. One month post-treatment, the joint group demonstrated significantly higher rates of CR, ORR, and DCR compared to the control group (P < 0.05). Three days after treatment, the joint group showed elevated levels of ALT, AST, and TBIL but reduced levels of ALB and AFP compared to the control group (P < 0.05). The median OS was 18 months for the control group and 25 months for the joint group, while the median PFS was 15 months for the control group and 22 months for the joint group, with significant differences observed (log-rank: χ 2 = 7.824, 6.861, respectively; P = 0.005, 0.009, respectively). The incidence of adverse reactions was not significantly different between the groups (P > 0.05). The combination of small particle DEB-TACE and sorafenib significantly improves both short- and long-term outcomes in the treatment of unresectable liver cancer while preserving liver function.

Incorporating ALBI Grade with Geriatric Nutritional Risk Index Enhances Hepatocellular Carcinoma Risk Stratification

Plain Language SummaryNutritional assessment is often overlooked in hepatocellular carcinoma (HCC) management despite its prognostic value. Geriatric nutritional risk index (GNRI), an objective measure of nutritional status, has shown significant prognostic relevance in HCC. Our research investigates the integration of the albumin-bilirubin (ALBI) grade with the GNRI to enhance prognostic stratification for patients with HCC. Utilizing data from a large nationwide registry cohort of 16,416 HCC patients, we examined the combined impact of ALBI grade and GNRI on overall survival in patients with HCC. Our findings demonstrate that incorporating ALBI grade with GNRI significantly improves risk stratification and provides a more precise prognosis, particularly in patients with preserved liver function (ALBI grade 1/2). Our results underscore the importance of integrating nutritional assessments into HCC management to enhance prognostic accuracy and optimize treatment plans.

Sequential living donor liver transplantation after liver resection optimizes outcomes for patients with high-risk hepatocellular carcinoma

BackgroundHepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality. While liver transplantation (LT) provides the best long-term survival, it is constrained by organ scarcity and strict criteria. Liver resection (LR) is often the initial treatment for patients with solitary tumors and preserved liver function. The high recurrence rates associated with LR has prompted the exploration of sequential living donor liver transplantation (seqLDLT) after LR as a strategy for HCC patients with high-risk of recurrence. MethodsWe analyzed data from 27 adult patients who underwent seqLDLT after LR for HCC at Kaohsiung Chang Gung Memorial Hospital (KCGMH) between June 1994 and December 2023. Patients were selected based on high-risk histopathological features post-LR or as part of downstaging strategy. Outcomes measured included overall survival (OS) and disease-free survival (DFS). ResultsAmong 765 HCC patients who underwent LDLT, 204 received LR before LDLT, and 27 underwent seqLDLT. Five patients (19%) underwent living donor liver transplantation (LDLT) following LR as a downstaging strategy while the rest received seqLDLT as a preemptive strategy. The median age was 53.5 years with 85% males. Chronic hepatitis B was the predominant underlying disease (74%). The 1-, 3-, and 5-year OS and DFS rates were 100%, 96.0%, 96.0% and 100%, 96.2%, 96.2%, respectively, with two patients experiencing HCC recurrence. One patient died from HCC recurrence. High-risk histopathological features included microvascular invasion (52%), satellite nodules (15%), multiple tumors (26%), tumors > 5 cm (19%), and a total tumor diameter > 10 cm (7%). ConclusionsSeqLDLT offers a promising, tailored approach for managing HCC with adverse histopathologic features. Combining seqLDLT, downstaging strategies, and multidisciplinary treatments can achieve satisfactory OS and DFS in carefully selected patients, highlighting the need for refined criteria to identify the best candidates.

Clinical significance of surgical resection for hepatocellular carcinoma with portal vein invasion: a nationwide cohort study.

Hepatocellular carcinoma (HCC) with portal vein invasion (PVI) is considered an advanced stage with a poor prognosis. Although current guidelines recommend systemic treatment for HCC with PVI, surgical resection could produce acceptable outcomes in selected patients. This study aimed to identify the clinical significance of surgical resection for HCC with PVI patients using a large-scale nationwide registry. This retrospective, multicenter, observational cohort analyzed data from the Korean Primary Liver Cancer Registry. A total of 16,781 patients who were newly diagnosed with HCC between 2008 and 2018 were enrolled in this study. Patients with worse Child-Turcotte-Pugh scores (≥7) or performance status (≥2) were excluded. Among them, 998 patients who received treatment for HCC with PVI were included in the analysis and were divided into two groups: resection group of 151 (15.1%) and palliative group of 847 (84.9%) who received transarterial and systemic therapy according to the treatment intent. After matching the number and size of the tumors and model for end-stage liver disease (MELD) score between the groups, the final study cohort for analysis comprised 151 (26.6%) patients in the resection group and 417 (73.4%) in the palliative group. The primary endpoints were overall survival (OS) and cancer-specific survival (CSS). The number and maximum size of HCC did not differ between the resection and palliative groups after matching [1 (range, 1-5) vs. 1 (range, 1-6), P=0.11 and 5.5 (range, 1.2-20.6) vs. 6.0 (range, 1.0-20.5) cm, P=0.24, respectively]. Tumor markers, including alpha-fetoprotein (AFP) and protein induced by vitamin K absence or antagonist-II (PIVKA-II), also did not differ between the groups (P=0.29 and P=0.36, respectively). The 5-year OS and CSS rates of the resection and palliative groups were 44.8% and 17.4% (P<0.001) and 47.7% and 18.6% (P<0.001), respectively. Multivariate analysis showed that palliative treatment intent was the most significant risk factor for OS and CSS [odds ratio (OR) =2.24; 95% confidence interval (CI): 1.66-3.02; P<0.001 and OR =2.29; 95% CI: 1.68-3.12; P<0.001, respectively]. Surgical resection could significantly improve OS and CSS in selected HCC with PVI patients who have preserved liver function and performance status.

Optimizing Prognostic Precision in Hepatocellular Carcinoma: Integrating PWR with ALBI and PALPI Scores.

Enhancing prognostication in Hepatocellular Carcinoma (HCC) remains an unmet need, especially in patients with preserved liver function. This study aimed to integrate the Platelet-to-White Blood Cell Ratio (PWR) with albumin-bilirubin (ALBI) and platelets-albumin-bilirubin (PALBI) scores for improved assessment of mortality and treatment responses in hepatocellular carcinoma (HCC) patients. In this prospective study, 262 patients with hepatocellular carcinoma (HCC) were included, with basic data collected and followed up for one year or until death. All prognostic scores were calculated by integrating the PWR with the ALBI and PALBI scores, examining their relationship with treatment responses and mortality rates. The patients were mainly males (69.5%), aged 59.6 ± 8.09 years. The predictive power of the integrated PALBI+PWR score at different time points 1 (P 0.004), 3 months, and 6 months (P 0.004) overpowered all other scores. However, late at the 12-month follow-up, ALBI score had reported superiority on PALPI+PWR (AUC 0.631, 0.617), respectively. Regression analyses confirmed the high performance of PALBI+PWR factors in influencing treatment response (P 0.009-OR 0.562 (0.365 - 0.867)). Regarding mortality prediction, PALPI+PWR proved the highest efficacy in regression analysis (P <0.001) OR (2.451 (1.555 - 3.862). Integrating PWR with the PALBI score enhances prognostic precision in patients with HCC, offering improved predictive power for treatment responses and mortality in the early stages of HCC with preserved liver function.

Comparison of surgical outcomes between shunt surgery and devascularization in non-cirrhotic portal hypertension

Objective: Non-cirrhotic portal hypertension (NCPH) is the most common cause of portal hypertension and upper gastro-intestinal bleeding in children and adolescents in developing nations. It is characterized by features of portal hypertension with preserved liver function. Proximal splenorenal shunt (PSRS) and esophagogastric devascularization are the two most commonly performed surgeries for its management. The present study is aimed at comparison of surgical outcomes between these two procedures. Material and Methods: Between April 2018 and March 2022, prospectively maintained data of consecutive NCPH cases who underwent surgical intervention was reviewed retrospectively. Cases were categorized into two groups- shunt surgery and devascularization. The pre-operative characteristics, peri-operative morbidity and long-term outcomes were compared between the groups. Results: Of 112 cases who were treated during the study period, 54 cases which underwent surgery were included in the study. Of these, 20 cases underwent PSRS, and splenectomy and devascularization was performed in 34 cases. There was no difference in pre-operative variables between the two groups. Patients undergoing PSRS experienced longer duration of surgery (260 vs. 200 minutes, p&lt; 0.001), and those in the devascularization group had significantly greater operative blood loss (350 vs. 455 ml, p&lt; 0.001). Post-operative morbidity was comparable between the two groups. Hypersplenism was corrected in all cases and no cases reported rebleeding after median follow-up of 30 months. Three cases in each group developed features of portal biliopathy in follow up period. Conclusion: Both PSRS and devascularization procedures have comparable efficacy and safety in the management of NCPH.

Primary treatments for solitary hepatocellular carcinoma ≤ 3 cm: A systematic review and network meta-analysis.

Various treatment modalities are available for small solitary hepatocellular carcinoma (HCC), yet the optimal primary treatment strategy for tumors ≤ 3 cm remains unclear. This network meta-analysis investigates the comparative efficacy of various interventions on the long-term outcomes of patients with solitary HCC ≤ 3 cm. A systematic search of electronic databases from January 2000 to December 2023 was conducted to identify studies that compared at least two of the following treatments: surgical resection (SR), radiofrequency ablation (RFA), microwave ablation (MWA), and transarterial chemoembolization (TACE). Survival data were extracted, and pooled hazard ratios with 95% confidence intervals were calculated using a frequentist network meta-analysis. A total of 30 studies, comprising 2 randomized controlled trials and 28 retrospective studies, involving 8,053 patients were analyzed. Surgical resection showed the highest overall survival benefit with a p-score of 0.95, followed by RFA at 0.59, MWA at 0.23, and TACE, also at 0.23. Moreover, SR provided the most significant recurrence-free survival advantage, with a p-score of 0.95, followed by RFA at 0.31 and MWA at 0.19. Sensitivity analyses, excluding low-quality or retrospective non-matched studies, corroborated these findings. This network meta-analysis demonstrates that SR is the most effective first-line curative treatment for single HCC ≤ 3 cm, followed by RFA in patients with preserved liver function. The limited data on MWA and TACE underscore the need for further studies.

Real-World Study of Systemic Treatment after First-Line Atezolizumab plus Bevacizumab for Hepatocellular Carcinoma in Asia-Pacific Countries

Introduction: Atezolizumab plus bevacizumab is a commonly used first-line regimen for advanced hepatocellular carcinoma (HCC) treatment owing to its superior outcomes compared to sorafenib. However, optimal subsequent treatment options for patients with HCC who progressed on first-line atezolizumab plus bevacizumab remain unclear. Methods: This multinational, multi-institutional, retrospective study included patients with HCC from 22 centers in five Asia-Pacific countries who were treated with first-line atezolizumab plus bevacizumab, which was discontinued for any reason. The endpoints included progression-free survival (PFS) and overall survival (OS) according to patient characteristics and second-line regimens. Results: Between June 2016 and May 2023, 1,141 patients were treated with first-line atezolizumab plus bevacizumab, of whom 629 (55.1%) received subsequent treatment. Sorafenib and lenvatinib were the most commonly administered second-line regimens (53.9% and 25.6%, respectively). Overall, the median PFS and OS were 2.9 and 8.0 months, respectively. Lenvatinib had longer PFS (4.0 vs. 2.3 months) and OS (8.0 vs. 6.3 months) than sorafenib. Patients treated with tyrosine kinase inhibitor (TKI) plus immune checkpoint inhibitor (ICI) (n = 50, 8.3%) showed PFS and OS of 5.4 and 12.6 months, respectively. Lower tumor burden and lenvatinib or TKI plus ICI use were associated with longer second-line PFS. Preserved liver function was associated with improved OS. Conclusions: In patients with HCC who progressed on first-line atezolizumab plus bevacizumab, sorafenib and lenvatinib were the most commonly used second-line regimens in Asia-Pacific countries, with lenvatinib resulting in longer OS than sorafenib. The second-line TKI plus ICI combination exhibited promising efficacy, suggesting the potential role of continuing ICIs beyond disease progression.

The usefulness of head computed tomography in patients with known cirrhosis presenting to emergency department with suspected hepatic encephalopathy.

Computed tomography of the head (CT head) is frequently used for patients with cirrhosis presenting with suspected hepatic encephalopathy (HE). The primary aims of this study were to assess the frequency of CT head usage in this patient population and to determine whether these scans yielded significant findings. Our secondary aims were to identify factors associated with the decision to order CTs and whether patients who received CTs had different outcomes. A single-centre, retrospective chart review was performed. Patients presenting to the University of Alberta Hospital with cirrhosis and common liver disease aetiologies over a 27-month period were identified via discharge diagnosis codes. Charts of patients with suspected HE were manually identified. The use of a CT head was documented, as were patient demographics, cirrhosis aetiology, MELD, and outcomes. Comparisons were made between patients with and without CT head. A total of 119 encounters from 100 patients met our inclusion criteria. In 57% of encounters, a CT scan was performed on presentation. None of these CT scans had significant findings. Patient factors associated with the decision to order CT included older age, more preserved liver function, and longer length of time between patient's current and previous presentations. Patients who did not receive CT head had higher in-hospital mortality, which was likely reflective of more severe underlying liver dysfunction in this group. The frequency of CT head usage in the studied patient population was high while the yield was low. This calls into question the usefulness of CT head in this population.

A real-world study of tyrosine kinase inhibitors plus anti-PD-1 immunotherapy with or without chemoembolization for hepatocellular carcinoma patients with main portal vein invasion.

Although systemic therapies are recommended for hepatocellular carcinoma (HCC) patients with main portal vein (MPV) invasion and preserved liver function, the outcome is limited. In the real-world, chemoembolization is a commonly used local treatment for advanced HCC. To evaluate whether the additional chemoembolization treatment yields survival benefits compared to systemic therapy for HCC patients with MPV invasion and preserved liver function (Child-Pugh score ≤ B7) in a real-world study from multiple centers. Between January 2020 and December 2022, 91 consecutive HCC patients with MPV invasion who received either systemic medical therapy (i.e., tyrosine kinase inhibitors (TKIs) plus anti-PD-1 immunotherapy, S group, n = 43) or in combination with chemoembolization treatment (S-T group, n = 48) from five centers were enrolled in the study. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS) and treatment response. Adverse events (AEs) related to treatment were also recorded. Survival curves were constructed with the Kaplan-Meier method and compared using the log-rank test. The baseline characteristics were comparable between the two groups. The mean number of chemoembolization sessions per patient was 2.1 (range 1-3). The median OS was 10.0months and 8.0months in the S-T group and S group, respectively (P = 0.254). The median PFS between the two groups was similar (4.0months vs. 4.0months, P = 0.404). The disease control rate between the S-T and S groups were comparable (60.4% vs. 62.8%, P = 0.816). Although no chemoembolization-related deaths occurred, 13 grade 3-4 AEs occurred in the S-T group. The results of the real-world study demonstrated that additional chemoembolization treatment did not yield survival benefits compared to TKIs plus anti-PD-1 immunotherapy for the overall patients with advanced HCC and MPV invasion.

No lipiodol, no beads-another transcatheter arterial chemoembolization (TACE) with fine cisplatin powder and porous gelatin particles for TACE-naïve, multifocal, up-to-seven out hepatocellular carcinoma.

The Japanese Interventional oncology group (JIVROSG) showed the efficacy and safety of nonselective transarterial chemoembolization (TACE) with fine cisplatin powder (diamminedichloroplatinum; DDP-H) (65 mg/m2) and porous gelatin particles (DDP-H TACE) without lipiodol for extensive multifocal hepatocellular carcinoma (HCC). However, there are no studies on this method following the JIVROSG study. Therefore, we aimed to evaluate the efficacy of this new DDP-H TACE and its effect on liver function. We retrospectively reviewed the medical records of TACE-naïve patients with multifocal HCC (Child-Pugh class A, up-to-seven out, no prior history of systemic therapy) who underwent whole-liver DDP-H TACE between January 2006 and December 2019. Sixty patients were included in this study. The median age of the patients was 71 (range, 35-88) years. The median maximum size of tumors was 26 (range, 8-184) mm; 86.7% of patients met the up-to-11 criteria out. The overall survival duration was 30.3 months. At the time of initial evaluation (median, 45 days), the overall response rate was 65.0%; the disease control rate was 86.7% based on the modified response evaluation criteria in solid tumors guideline. Although nine patients' liver function had deteriorated to Child-Pugh class B at initial evaluation, six of them recovered to Child-Pugh class A. Only three patients (5%) showed permanently impaired liver function. Whole-liver DDP-H TACE without lipiodol or beads effectively reduced tumors and preserved liver function.
