Long-term Favorable Efficacy of Regular and Repeated Hospitalizations with a Personalized Diet and Exercise Treatment for Steatotic Liver Disease.

Objective The long-term impact of personalized diet and exercise programs for steatotic liver disease (SLD) remains unclear. Materials The subjects of this retrospective cohort study included 104 consecutive Japanese patients with SLD. The long-term treatment efficacy of personalized diet and exercise treatment was evaluated two years after the start of observation. Regular and repeated hospitalizations every 6 months (RRH group, n=23) indicated the 4 times of the number of hospitalizations, and irregular hospitalizations (IH group, n=56) showed the 1 to three times. The group without hospitalization was defined as the no hospitalization group (NH group, n=25). To balance confounding biases, the difference in treatment efficacy between the RRH and IH groups was evaluated using propensity score (PS)-matched analysis. A diet of 25 to 30 kcal/kg multiplied by ideal body weight (BW) daily, and aerobic and resistance exercise (exercise intensity of 4 to 5 metabolic equivalents daily, respectively) was performed for 6 days. Results At 2 years compared to baseline, the decrease rates of liver function tests, HbA1c, and physical findings in the RRH group were significantly higher than those in the NH or IH groups by multiple comparisons. According to the liver function tests and physical findings, the rate of decrease in the RRH group (17 cases) was significantly higher than that in the IH group (17 cases) using a PS-matched analysis. Conclusion The present study indicated the long-term favorable efficacy of personalized diet and exercise programs for SLD. In particular, this RRH program was effective in improving the findings of liver function tests and might help to sustain diet and exercise.

Comparison of spin-echo echo planar imaging and gradient-recalled echo sequences in magnetic resonance elastography of liver at 1.5T same MRI scanner.

PURPOSE: Magnetic resonance elastography (MRE) is used to measure liver stiffness with gradient-recalled echo (GRE)-based and spin-echo echo planar imaging (SE-EPI)-based sequences. We compared the liver stiffness (LS) values of the two sequences on a 1.5-T MR imaging scanner. METHODS: This is a retrospective study. An MRE imaging section was obtained from a horizontal section of the liver. Region of interest was drawn on the elastogram, and the mean LS and pixel values were measured and compared. The correlations between proton density fat fraction, R2* values, and biochemical data from electronic medical records were confirmed, and multivariate analysis was performed. RESULTS: The mean LS values were 3.01 ± 1.78 kPa for GRE and 3.13 ± 1.57 kPa for SE-EPI, showing excellent agreement and a strong correlation between the two sequences (correlation coefficient r = 0.96). The mean pixel values were 369.5 ± 142.7 pixels for GRE and 490.1 ± 197.9 pixels for SE-EPI, showing a significant difference by the Wilcoxon rank sum test (p < 0.01). There were no LS unmeasurable cases in SE-EPI, but seven (2.5%) were unmeasurable in GRE, and multivariate analysis showed a significant difference with p < 0.001 in R2* values (mean, 92.7 Hz) for the GRE method. CONCLUSION: The GRE and SE-EPI methods were comparable for LS measurements in 1.5-T liver MRE, indicating that SE-EPI MRE is more useful because GRE MRE may not measure cases with high R2* values and the region of interest tends to be smaller.

Impact of genetic polymorphism on personalized diet and exercise program for steatotic liver disease.

AIMS: The effects of genetic polymorphism on a personalized diet and exercise program for steatotic liver disease (SLD) are still unclear. METHODS: Participants of this retrospective cohort study were 203 Japanese patients with SLD diagnosed by abdominal ultrasonography. All of them were introduced the personalized diet and exercise treatment. A diet of 25-30 kcal/kg multiplied by ideal body weight (BW) daily and aerobic and resistance exercise (exercise intensity of 4-5 metabolic equivalents daily, respectively) were performed for 6 days. Treatment efficacy was evaluated in terms of the rate of decrease of liver function tests, glycolipid metabolism markers, physical findings, image findings, and cardiovascular disease (CVD) risk score at 6 months compared with baseline. Furthermore, the impact of genetic polymorphism was also investigated. RESULTS: At 6 months compared with baseline, liver function tests (AST, ALT, γGTP), glycolipid metabolism markers (hemoglobin A1c, triglycerides [TG], low-density lipoprotein cholesterol), physical findings (BW, body mass index), image finding (liver stiffness measurement), and CVD risk score (Suita score) improved significantly. There was no significant difference in treatment efficacy, except for the rates of decrease of TG, according to genotype PNPLA3 rs738409, TM6SF2 rs58542926, and HSD17B13 rs6834314. The rates of decrease of TG with TM6SF2 CT were significantly higher than those with CC or TT, and the rates of TG with HSD17B13 AA were significantly higher than those with AG by multiple comparisons. CONCLUSION: Personalized diet and exercise program for SLD improved liver function tests, physical findings, glycolipid metabolism markers, and CVD risk score. Genetic polymorphism might partially affect treatment efficacy. Further studies should be performed to develop an individualized program for SLD, considering genetic polymorphism.

Clinical outcome after cessation of nucleos(t)ide analog treatment in chronic hepatitis B patients who achieved HBsAg seroclearance.

BACKGROUND: We determined the long-term clinical outcome and the durability of treatment cessation after HBsAg seroclearance following nucleos(t)ide analog (NA) therapy in patients with chronic hepatitis B (CHB). METHODS: We analyzed virological relapse (VR), HBsAg reversion, clinical relapse, and changes in HBsAg and HBcrAg levels by iTACT assay after treatment cessation of 90 CHB patients who achieved HBsAg seroclearance by NA treatment. RESULTS: Median age of patients at treatment cessation was 57 years. Median duration of NA treatment and follow-up from cessation of NA were 9.25 and 5.2 years, respectively. Although VR occurred in 19 of 90 (21.1%) patients, HBV DNA levels of 18 patients had temporal elevations and sustained levels under the detection level thereafter. HBsAg reversion using Architect HBsAg QT assay occurred in six patients (6.7%) after cessation of NA. Five patients had temporal HBsAg level elevations and sustained levels under the detection level thereafter. One patient had virological and clinical relapse at 6 months after cessation of NA, and received NA re-treatment. HBsAg levels by iTACT assay from end of treatment (EOT) gradually decreased and in 18 of 28 (64%) patients reached an undetectable level at 5 years after EOT. In contrast, HBcrAg levels by iTACT assay slowly decreased, and in 8 of 29 patients (28%) reached an undetectable level at 5 years after EOT. CONCLUSIONS: Patients receiving NA treatment who achieved HBsAg seroclearance as determined by HBsAg QT assay rarely experienced virological or clinical relapse after the cessation of treatment.

Utility of liver stiffness measurement in the diagnosis of sinusoidal obstruction syndrome/veno-occlusive disease after hematopoietic stem cell transplantation.

PURPOSE: We aimed to assess the role of liver stiffness measurement (LSM), evaluated using transient elastography (TE), for the diagnosis of sinusoidal obstruction syndrome (SOS)/veno-occlusive disease (VOD), a complication of hematopoietic stem cell transplantation (HSCT). METHODS: In this retrospective study, ultrasonography (US) and LSM were performed on 86 adult patients (55 men and 31 women) undergoing HSCT between January 2016 and December 2022. Characteristics and changes in liver stiffness (LS) were compared between patients with and without SOS/VOD. RESULTS: Of the 86 patients, 14 were diagnosed with SOS/VOD. A significant increase in LS (ranging from 12.6 to 55.1 kPa, median 23.8 kPa) compared to pre-HSCT values was observed in all patients who developed SOS/VOD. The area under the receiver operating characteristic curve (AUROC) for the diagnosis of SOS/VOD was 0.9663 (0.933-0.995) for LS ≥ 17.4 kPa after HSCT. Post-transplant LS exceeded 17.4 kPa in all 14 patients in the SOS/VOD group (100%) and in seven patients in the non-SOS/VOD group (9.7%). The sensitivity and specificity were 100% and 90.3%, respectively. AUROC for the diagnosis of SOS/VOD was 0.973 (0.943-1.000) for LS increase ≥ + 12.6 kPa from baseline after HSCT. The change of ≥ + 12.6 kPa from baseline was observed in all 14 patients in the SOS/VOD group (100%) and in four patients in the non-SOS/VOD group (5.6%). The sensitivity and specificity were 100% and 94.4%, respectively. CONCLUSION: LSM using TE may contribute to establishing the diagnosis of SOS/VOD after HSCT.

A new imaging classification for safer radial access visceral intervention of the liver and optimal case selection: A preliminary report.

AIM: The aim of this study was to evaluate the use of a new classification for safer transradial access hepatic interventional radiology, based on preoperative evaluation of the location of the left subclavian artery bifurcation in the aortic arch. METHODS: A total of 38 consecutive patients with hepatocellular carcinoma and 74 sessions of radial access for visceral intervention (R.A.V.I.) were reviewed. We classified the location of the left subclavian artery bifurcation in the aortic arch in three areas using an oblique view computed tomography image matched with the curve of the aortic arches according to a new criteria Three Areas Criteria For R.A.V.I. (named "TAC-F-R"), and measured the required time from initial left radial artery arteriography to celiac artery or superior mesenteric artery arteriography. RESULTS: The median time required for left radial artery arteriography to the celiac artery or superior mesenteric artery arteriography in each of the three areas were: area A, 0:11:10 (h, min, s); area B, 0:14:44; and area C, 0:31:51. There were significant differences between each area after Bonferroni correction (p < 0.01; A vs. B, p = 0.086; A vs. C, p = 0.001; and B vs. C, p = 0.045), with areas A and B requiring a significantly shorter time. Finally, no patients showed neurogenic disfunction within 1 week after the R.A.V.I. CONCLUSIONS: The new classification, "TAC-F-R," for safer transradial access hepatic interventional radiology is effective for avoiding difficult cases, and selects more suitable patients with hepatocellular carcinoma for the R.A.V.I.

Favorable Impact of Serum TERT C228T for Prognosis after Surgical Resection for Liver Cancer.

INTRODUCTION: Personalized medicine and molecular therapies with the diagnosis of somatic genetic alterations are expected to be developed for liver cancer. Nevertheless, it is unknown whether a mutation in the telomere reverse transcriptase promoter (TERT C228T) in serum cfDNA might be useful for making prognostic predictions after surgical resection for primary liver cancer. METHODS: This cohort study retrospectively investigated 111 patients who had undergone surgical resection of liver cancer for the first time. We investigated the differences between clinicopathological features and prognosis according to classification of three tumor markers, including AFP, PIVKAII, and TERT C228T. RESULTS: Multivariate analysis identified etiology (fatty liver disease vs. HBV odds ratio [OR] 6.853) and fibrosis stage (2-4, OR: 0.137) as determinants of TERT C228T-positive liver cancer with normal levels of AFP and PIVKAII (TERT single positive liver cancer). TERT single positive (Yes, OR: 0.301), fibrosis (FIB)-4 index (≥3.25, OR: 2.038), Child-Pugh classification (B, OR: 4.975), and number of tumors (≥2, OR: 4.098) were identified as determinants of the recurrence of liver cancer. TERT single positive (Yes, OR: 3.311), FIB-4 index (≥3.25, OR: 0.433), and number of tumors (≥2, OR: 0.262) were identified as determinants of disease-free survival. CONCLUSIONS: Our results highlight the impact of classification of prognostic tumor markers. TERT single positive is one predictor of favorable prognosis after surgical resection for liver cancer.

Efficacy of the Combination of Systemic Sequential Therapy and Locoregional Therapy in the Long-Term Survival of Patients with BCLC Stage C Hepatocellular Carcinoma.

BACKGROUND: The aim of this study was to evaluate the clinical impact of a combination of systemic sequential therapy and locoregional therapy on the long-term survival of patients with Barcelona Clinic Liver Cancer (BCLC) stage C hepatocellular carcinoma (HCC). METHODS: Sixty-four consecutive patients with intrahepatic target nodules who had initially received systemic therapy (lenvatinib and atezolizumab plus bevacizumab) were reviewed. The clinical impact of the combined use of systemic sequential therapy and locoregional therapy was evaluated by determining overall survival (OS). The combined use of systemic sequential therapy with more than two agents and locoregional treatment was defined as multidisciplinary combination therapy (MCT), while only systemic sequential therapy and repeated locoregional-treatment was defined as a single treatment procedure (STP). RESULTS: R0 resection, MCT, and STP resulted in significantly better OS compared with no additional treatment (median OS, not reached vs. 18.2 months and 12.6 vs. 8.1 months, respectively; p = 0.002). Multivariate analysis confirmed that the use of R0 resection and MCT were associated with better OS (hazard ratio [HR]; 0.053, p = 0.006 and 0.189, p < 0.001, respectively) compared with that for STP (HR; 0.279, p = 0.003). CONCLUSIONS: MCT is may effective in patients with BCLC stage C HCC and intrahepatic target nodules who have previously received systemic therapy-based treatment.

Treatment efficacy of diet and exercise program for fatty liver and pretreatment predictors.

AIMS: Both diet and exercise counseling are recommended for patients with fatty liver, including nonalcoholic fatty liver disease (NAFLD), to achieve weight loss goals. However, data evaluating treatment efficacy are limited. METHODS: The subjects of this retrospective cohort study were 186 consecutive Japanese cases with fatty liver diagnosed by abdominal ultrasonography. Treatment efficacy and predictive factors of "Hospitalization Program for Improvement Purpose for Fatty Liver" as a combined diet and aerobic and resistance exercise program were evaluated according to the hospitalization group (153 cases) or the no hospitalization group (33 cases). To balance the confounding biases, treatment efficacy was evaluated using propensity score-matched analysis. In the hospitalization group, a diet of 25-30 kcal/kg multiplied by ideal body weight (BW) daily and aerobic and resistance exercise (exercise intensity of 4-5 metabolic equivalents daily, respectively) were performed for 6 days. RESULTS: In liver function tests and BW at 6 months compared with baseline, the rates of decrease of the hospitalization group (24 cases) were significantly higher than those of the no hospitalization group (24 cases), using propensity score-matched analysis. In markers of glycolipid metabolism and ferritin levels, the rates of the hospitalization group were not different from those of the no hospitalization group. In the hospitalization group (153 cases), multivariate regression analysis identified the etiology of non-NAFLD, the presence of diabetes mellitus, and large waist circumference as independent predictors of decreased rates of hemoglobin A1c levels. CONCLUSION: The diet and exercise program for fatty liver improved liver function tests and BW. Further study should be performed to develop a feasible and suitable program.

Simple Predictive Markers and Clinicopathological Features of Primary Liver Cancer following HCV Clearance with Direct-Acting Antivirals.

INTRODUCTION: Simple predictive markers enabling even nonspecialized medical doctors and clinicopathological features of primary liver cancer (PLC) following HCV clearance with direct-acting antivirals (DAAs) are unclear. METHODS: The subjects of this retrospective study were 2,476 patients following HCV clearance with DAAs. All patients were confirmed to be PLC-free before and during DAAs. RESULTS: PLC was diagnosed in 73 patients during the follow-up, with an incidence rate per 1 000 person-years of 5.9. The annual rate of PLC during the first 6 years was 0.6%. Multivariate analysis identified gender, GGT, and FIB-4 index as the significant determinants of PLC. According to a combination of these risk factors, the cumulative PLC incidence rates were significantly different among the five subgroups based on the number of PLC risk scores. In 73 patients with PLC, the rates of abnormal AFP, PIVKAII, and serum TERT C228T positive were 37.0, 32.4, and 22.2%. PIVKAII levels in BCLC stage A and B were significantly higher than those in stage 0. In 41 patients, who underwent surgical resection for PLC, maximum tumor diameters of abnormal PIVKAII were significantly larger than those of normal PIVKAII. PLC of abnormal PIVKAII significantly indicated presence of vp more than that of normal PIVKAII, and did not contain well-differentiated HCC. CONCLUSIONS: Combination of simple markers, enabling even nonspecialized medical doctors, is useful for the evaluation of PLC risk following HCV clearance with DAAs. However, imaging studies are regularly recommended for the early detection of PLC.

Well-preserved liver function enhances the clinical impact of curative-intent subsequent treatment during lenvatinib treatment for unresectable hepatocellular carcinoma.

BACKGROUND: The aims of this study were to evaluate the clinical impact of curative-intent subsequent treatment on overall prognosis in lenvatinib-treated hepatocellular carcinoma (HCC) patients. METHODS: Eighty-three consecutive patients with intrahepatic target nodules who received lenvatinib were reviewed. The clinical impact of curative-intent subsequent treatments was investigated through analysis of overall survival (OS) according to pathological deterioration stratified by mALBI grade. RESULTS: In patients with mALBI grade 1 and 2a liver function, R0 resection and lenvatinib-transarterial chemoembolization (lenvatinib-TACE) sequential therapy resulted in significantly better OS compared with other, non-curative-intent subsequent therapy and lack of additional treatment (median OS, 37.6 vs 29.0 months and 17.1 vs 8.9 months, respectively; P < 0.001). Multivariate analysis confirmed that use of R0 resection and lenvatinib-TACE sequential therapy were associated with better OS (hazard ratio [HR], 0.021; P < 0.001 and 0.108; P < 0.001) compared with other, non-curative-intent subsequent treatment (HR 0.256; P = 0.010). In contrast, in patients with mALBI grade 2b liver function, multivariate analysis confirmed higher treatment efficacy for non-curative-intent subsequent treatment with respect to OS (HR 0.041; P < 0.001) compared with R0 resection and lenvatinib-TACE sequential therapy (HR 0.057; P = 0.027 and 0.063; P = 0.001). CONCLUSION: Curative-intent subsequent treatment is more useful for HCC patients with better liver function (mALBI grade 1 and 2a) and intrahepatic target nodules who have received lenvatini b-based treatment.

The Impact of Lenvatinib on Tumor Blood Vessel Shrinkage of Hepatocellular Carcinoma during Treatment: An Imaging-Based Analysis.

INTRODUCTION: When lenvatinib is administered to people with hepatocellular carcinoma (HCC), tumor blood flow is reduced due to the inhibition of the vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR). Few studies have examined the decrease in tumor blood flow with respect to changes in tumor blood vessels (TBVs) in clinical practice. We investigated the mechanism of tumor blood flow control by investigating changes in the diameter of relatively large TBVs in large-sized lesions with high blood flow. METHODS: From January 2011 to October 2021, patients receiving lenvatinib for unresectable intrahepatic HCC at Toranomon Hospital, Tokyo, Japan, were considered for inclusion. We investigated the TBV diameter in the arterial phase of dynamic computed tomography before treatment and its change over time (2-12 weeks after lenvatinib initiation). The relationship between changes in TBV diameter and prognosis was also examined. RESULTS: Of 114 patients treated with lenvatinib for HCC, 26 patients who had intrahepatic lesions with a tumor diameter of 30 mm or more enrolled in the study. The median tumor and TBV diameters before treatment were 58 mm and 2.55 mm, respectively. Twenty-five patients (96%) had a shrinkage in TBV diameter 2-12 weeks after lenvatinib administration. The maximum TBV diameter shrinkage of 20% or more was observed in 19 patients (73%), and progression-free survival was prolonged in these patients compared to the group with less than 20% TBV diameter shrinkage (p = 0.039). DISCUSSION/CONCLUSION: Due to the antiangiogenic effect of lenvatinib, a shrinkage in the TBV diameter of HCC was observed. The shrinkage of TBV may be regarded as a process of normalization of TBVs. The shrinkage of TBVs in imaging analysis may be associated with improved prognosis; however, additional studies are still required.

A case of drug-induced acute liver failure caused by corticosteroids.

We report a 61-year-old man treated with betamethasone for sudden-onset deafness. Several days later, he had a temperature > 38 °C. He sought care at another hospital and was admitted based on abnormal liver function tests (aspartate aminotransferase [AST], 866 IU/L [normal < 31 IU/L] and alanine aminotransferase [ALT] 1524 IU/L [normal < 31 IU/L]). Liver function improved daily and the patient was discharged from the hospital after 5 days. Two days after discharge, he had a recurrent fever and liver dysfunction. After admission to our hospital, liver function improved spontaneously. A liver biopsy was performed, but a diagnosis was not established; however, a tentative diagnosis of antinuclear antibody-negative autoimmune hepatitis was made and the patient was started on prednisolone (30 mg). Two days later, he developed a fever and persistent liver dysfunction, thus the prednisolone was discontinued. The next day, the AST and ALT increased significantly (18,000 and 12,000 U/L, respectively). Because the level of consciousness was altered, plasma exchange was started for acute liver failure. After discontinuing the prednisolone, the hospital course was uneventful. Drug-induced liver injury due to corticosteroids is rare. Herein, we report a patient with acute liver failure who survived with timely treatment.

A Collaborative Study on the Classification of Silicone Oil Droplets and Protein Particles Using Flow Imaging Method.

In this study, we conducted a collaborative study on the classification between silicone oil droplets and protein particles detected using the flow imaging (FI) method toward proposing a standardized classifier/model. We compared four approaches, including a classification filter composed of particle characteristic parameters, principal component analysis, decision tree, and convolutional neural network in the performance of the developed classifier/model. Finally, the points to be considered were summarized for measurement using the FI method, and for establishing the classifier/model using machine learning to differentiate silicone oil droplets and protein particles.

Impact of Poloxamer 188 Material Attributes on Proteinaceous Visible Particle Formation in Liquid Monoclonal Antibody Formulations.

Surfactants such as Poloxamer 188 (PX188) play an important role in controlling particle formation in biotherapeutic formulations due to interfacial stresses. This study demonstrates for the first time that hydrophobicity of PX188 is a potential critical material attribute (CMA) as far as control of visible particle (VP) formation is concerned. We have found that within PX188 lots satisfying pharmacopeial specifications, there is variability in material attributes such as hydrophobicity, as determined from their reversed-phase high-performance liquid chromatography profiles. However, it currently remains unknown how such variability in hydrophobicity of PX188 affects surfactant function and VP formation. Here, we compared the effect of seven PX188 lots in two monoclonal antibody drug product formulations under various stress conditions. Notably, proteinaceous VP formation was reduced while using a PX188 lot with higher hydrophobicity. Our findings emphasize the importance of monitoring lot-to-lot variability of PX188 and provide insight into potential CMA for improving and controlling material attributes of PX188 for use in liquid biotherapeutic formulations.

Serum TERT C228T is an important predictor of non-viral liver cancer with fatty liver disease.

BACKGROUND: Molecular therapies and precision medicine are expected to be developed for liver cancer based on the diagnosis of DNA somatic alterations. However, it remains unclear whether TERT promoter mutation (TERT C228T) in serum cfDNA is useful for the diagnosis of liver cancer with non-viral fatty liver disease (FLD). METHODS: This retrospective cohort study examined 258 Japanese patients who had a confirmed diagnosis of primary liver cancer. We investigated the factors associated with TERT C228T and abnormal levels of liver cancer-specific tumor markers (AFP and PIVKAII) in serum samples. RESULTS: Multivariate analysis identified the etiology of FLD, vascular invasion, and non-cirrhosis as determinants of TERT C228T-positive liver cancer. Rates of positive TERT C228T in FLD were significantly higher than those of HBV and HCV. Conversely, rates of abnormal AFP in FLD were significantly lower than those of HBV and HCV. Viral suppression of HBV/HCV and alcohol intake did not affect TERT C228T, but AFP was significantly reduced by viral suppression. The rates of positive TERT C228T were significantly lower in HCV patients with viral clearance than those of FLD patients. CONCLUSION: Our results highlight the importance of serum TERT C228T for the detection of non-viral FLD-related liver cancer. TERT C228T is a tumor marker that might not be influenced by inflammation.

The useful predictors of zinc deficiency for the management of chronic liver disease.

BACKGROUND: Zinc deficiency is likely to occur in chronic liver disease. The aim of this study was to determine the prevalence of zinc deficiency in different types of chronic liver disease and to identify the factors that predicted low serum zinc levels. METHODS: The study was an observational single-center design. We obtained the medical records of 666 patients with chronic liver disease whose serum zinc levels had been measured. The cutoff value for zinc deficiency was a serum level < 70 µg/dL. RESULTS: Serum zinc levels in the alcoholic liver disease (ALD) group were significantly lower than in the other groups (hepatitis C virus [HCV], hepatitis B virus [HBV], and other cause) (P < 0.01). The CONUT and ALBI score (r = 0.527, P < 0.01), serum zinc level and ALBI score (r = - 0.607, P < 0.01), and serum zinc level and CONUT score (r = - 0.465, P < 0.01) correlated with each other. The prevalence of zinc deficiency were 44.8%, 63.2%, 86.7%, 97.1%, and 100% in the mALBI grade 1-CONUT normal, CONUT undernutrition, and mALBI grade 2a, 2b, and 3 groups, respectively. Multivariate analysis identified ALD, CONUT score, aspartate aminotransferase, and hemoglobin as significant, independent predictors of zinc deficiency (P < 0.05). CONCLUSIONS: This study identified ALD, CONUT score, aspartate aminotransferase, and hemoglobin as predictors of zinc deficiency in chronic liver disease. The rate of zinc deficiency is high even in patients classified as mALBI grade 1, especially in ALD, while caution may be required in those classified as mALBI grade 1-CONUT undernutrition.

Pretreatment Positron Emission Tomography with 18F-Fluorodeoxyglucose May Be a Useful New Predictor of Early Progressive Disease following Atezolizumab plus Bevacizumab in Patients with Unresectable Hepatocellular Carcinoma.

BACKGROUND AND AIMS: The aim of this study was to identify the utility of 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) as a predictor of early progressive disease (e-PD) in patients with hepatocellular carcinoma (HCC) treated with atezolizumab plus bevacizumab (Atezo/Bev). METHODS: Twenty consecutive patients with measurable intrahepatic target nodules who received Atezo/Bev treatment were reviewed. The oncological aggressiveness of tumors estimated by 18F-FDG-PET/CT was analyzed using the rate of e-PD within 12 weeks and early progression-free survival (e-PFS) and overall survival (OS). Multivariate analysis was used to identify potential confounders for PD during Atezo/Bev therapy. RESULTS: Using the Response Evaluation Criteria in Solid Tumors version 1.1, a tumor-to-normal liver ratio (TLR) ≥2, indicating higher oncological aggressiveness in HCCs, was associated with lower objective response rates compared with TLR values <2 (18% vs. 33%, respectively). Moreover, TLR values ≥2 were significantly associated with higher e-PD rates compared with TLR values <2 (64% vs. 11%, respectively) and worse e-PFS (p = 0.021). In multivariate analysis, TLR ≥2 showed marginal significance as a predictor of e-PD (p = 0.053), and utility as a predictor for worse e-PFS (hazard ratio, 7.153; 95% confidence interval, 1.258-40.689; p = 0.027). In contrast, no significant differences in OS with/without e-PD were observed during the treatment course. In this study, 8 patients experienced e-PD and almost 40% of patients experienced acceptable disease control following subsequent lenvatinib treatment. CONCLUSION: Pretreatment 18F-FDG-PET/CT may be a useful new predictor of e-PD and may enable early decision-making based on early treatment changes following Atezo/Bev treatment of HCC.

Clinicopathological assessment of steatohepatitic hepatocellular carcinoma.

AIM: To compare the clinicopathological features of typical steatohepatitic HCC (SH-HCC) with other HCCs. METHODS: Subjects were 486 patients with untreated HCC who underwent hepatectomy at our hospital from January 2015 to December 2020. We compared patient backgrounds, preoperative laboratory data, imaging findings (ultrasonography, computed tomography [CT], and magnetic resonance imaging [MRI]), and postoperative pathological findings (tumor and background of liver). The Liver Imaging Reporting And Data System (LI-RADS) was used to examine CT and MRI findings. RESULTS: Typical SH-HCCs were significantly different from other HCCs with respect to age, hepatitis B virus (HBV) infection, and nonalcoholic steatohepatitis (NASH). Diabetes and hyperlipidemia were also significantly more common. Regarding histopathology, tumor size and background steatosis were significantly different between groups. Although ultrasonography, CT, and MRI could each alone diagnose SH-HCCs with a diameter < 20 mm in ≥ 50% of patients, the combined use of these tests improved diagnostic accuracy. By LI-RADS, 87% of SH-HCC cases were classified as LR-5, which are considered to be malignant tumors. CONCLUSIONS: It seems possible to diagnose SH-HCC by combining ultrasonography, CT, and MRI.
