RESUMO
OBJECTIVE: Metabolic dysfunction-associated steatotic liver disease (MASLD) and cardiometabolic conditions affect populations across economic strata. Nevertheless, there are limited epidemiological studies addressing these diseases in low (LICs) and lower-middle-income countries (lower MICs). Therefore, an analysis of the trend of MASLD and cardiometabolic conditions in these countries is necessary. METHODS: From 2000 to 2019, jointpoint regression analysis was employed to calculate the prevalence, mortality, and disability-adjusted life years (DALYs) for cardiometabolic conditions including MASLD, type 2 diabetes mellitus (T2DM), dyslipidemia (DLP), hypertension (HTN), obesity, peripheral artery disease (PAD), atrial fibrillation and flutter (AF/AFL), ischemic heart disease (IHD), stroke, and chronic kidney disease from HTN and T2DM, in LICs and lower MICs (according to the World Bank Classification 2019) using the Global Burden of Disease 2019 data. RESULTS: Among the eleven cardiometabolic conditions, MASLD (533.65 million), T2DM (162.96 million), and IHD (76.81 million) had the highest prevalence in LICs and Lower MICs in 2019. MASLD represented the largest proportion of global prevalence in these countries (43 %). From 2000 to 2019, mortality in LICs and lower MICs increased in all cardiometabolic conditions, with obesity-related mortality having the highest increase (+134 %). During this timeframe, there were increased age-standardized death rates (ASDR) from obesity, PAD, and AF/AFL. From all conditions, the DALYs-to-prevalence ratio was higher in LICs and lower MICs than the global average. CONCLUSION: The burden of MASLD and cardiometabolic conditions is increasing worldwide, with LICs and lower MICs experiencing higher (DALYs) disability per prevalence. As these conditions are preventable, counteracting these trends requires not only the modification of ongoing actions but also the strategizing of immediate interventions.

Ultrasonography is a noninvasive and widely accessible modality in clinical practice. Recently, ultrasonography has been used to evaluate tissue stiffness; the two representative techniques are transient elastography (FibroScan®) and shear wave elastography. These modalities are now generally used for the assessment of liver fibrosis, the prediction of hepatocarcinogenesis, and determining prognosis. In addition, shear wave elastography is available, not only for the liver but also for various other organs, including the breast and brain. In the breast and brain, shear wave elastography distinguishes malignant lesions from benign ones. Moreover, shear wave elastography can be useful for differentiating between ischemic and hemorrhagic strokes. This review summarizes the recent progress in transient elastography and shear wave elastography of the liver and introduces the advantages of ultrasonographic assessment of tissue stiffness in various organs, including the breast, brain, kidney, heart, thyroid, pancreas, muscle, and bone.

AIM: In patients with steatotic liver disease (SLD), significant hepatic fibrosis is a prognostic factor with various etiologies, including inflammation and metabolic dysfunction. This study aimed to investigate independent factors and profiles associated with significant hepatic fibrosis, including alanine aminotransferase (ALT) levels >30 U/L and metabolic dysfunction-associated SLD (MASLD), in health check-up examinees. METHODS: This single-center, retrospective, observational cohort study enrolled 1378 consecutive health checkup examinees from April 2018 to September 2022. Shear wave elastography (SWE) was performed during a routine ultrasound examination, and patients with liver stiffness ≥6.60 kPa were defined as having significant hepatic fibrosis. Patients were classified into nonsignificant hepatic fibrosis (n = 1220) or a significant hepatic fibrosis (n = 158) group according to this definition. RESULTS: In multivariate analysis, the independent factor for significant hepatic fibrosis was aging (≥65 years; OR 9.637, 95% CI 6.704-13.852, p < 0.0001). According to decision tree analysis, the initial classifier was aging (≥65 years). After aging, an ALT level >30 U/L was the second relevant factor for significant hepatic fibrosis, regardless of age. An undirected graphical model showed that an ALT level of >30 U/L was directly associated with significant hepatic fibrosis. In patients aged ≥65 years with an ALT level >30 U/L, significant hepatic fibrosis was observed in 52% of the patients. Meanwhile, in patients aged ≥65 years with an ALT level ≤30 U/L, MASLD was the third classifier, with significant hepatic fibrosis observed in 38% of patients. CONCLUSIONS: ALT levels >30 U/L and MASLD may be involved in the pathogenesis of significant hepatic fibrosis in patients aged ≥65 years.
RESUMO
This study aimed to evaluate the effect of lenvatinib (LEN) combined with transcatheter intra-arterial therapy (TIT) for advanced-stage hepatocellular carcinoma (HCC) after propensity score matching (PSM). This retrospective study enrolled 115 patients with advanced-stage HCC who received LEN treatment. The patients were categorized into the LEN combined with TIT group (n = 30) or the LEN monotherapy group (n = 85). After PSM, 38 patients (LEN + TIT group, n = 19; LEN monotherapy group, n = 19) were analyzed. The median overall survival (OS) in the LEN + TIT group was significantly higher than that in the LEN monotherapy group (median survival time (MST): 28.1 months vs. 11.6 months, p = 0.014). The OS in the LEN combined with transcatheter arterial chemoembolization and LEN combined with hepatic arterial infusion chemotherapy groups was significantly higher than that in the LEN monotherapy group (MST 20.0 vs. 11.6 months, 30.2 vs. 11.6 months, p = 0.048, and p = 0.029, respectively). Independent factors associated with OS were alpha-fetoprotein and LEN combined with TIT. The indications for LEN combined with TIT were age <75 years and modified albumin bilirubin (m-ALBI) grade 1. We concluded that LEN combined with TIT may improve prognosis compared with LEN monotherapy in patients with advanced-stage HCC.

BACKGROUND AND AIMS: We aimed to validate the predictive factors for tumor response and the prognostic impact of conversion therapy aimed at cancer- and drug-free states in patients with unresectable hepatocellular carcinoma (u-HCC) undergoing atezolizumab plus bevacizumab (Atez/Bev) therapy. METHODS: This retrospective study enrolled 156 patients who were Child-Pugh class A with u-HCC treated using Atez/Beva. The profile of objective response was investigated using decision-tree analysis. Progression-free, recurrence-free, and overall survival were assessed. RESULTS: The progression-free and overall survival were 6.1 and 18.0 months, respectively. Objective response and disease control rates were 32.0% and 84.0%, respectively. Decision-tree analysis revealed that neutrophil-to-lymphocyte ratio (NLR) <3, modified albumin-bilirubin grade (m-ALBI) 1 or 2a, and age < 75 were sequential splitting variables for the objective response, respectively. In the multivariate analysis, NLR <3 and m-ALBI grade 1 or 2a were identified as predictive factors for objective response. We successfully achieved eligibility for conversion therapy in 17 patients after Atez/Bev therapy significant response. Following conversion therapy, the curative therapy group, including surgical resection or radiofrequency ablation (RFA), had significantly higher recurrence-free survival than did the transcatheter arterial chemoembolization (TACE) and Atez/Bev discontinuation (surgical resection or RFA; not reached vs. TACE; 5.3 months, p = 0.008, Atez/Bev discontinuation; 3.9 months, p = 0.048, respectively) groups. CONCLUSIONS: NLR <3 and m-ALBI grade 1 or 2a were predictive factors for conversion therapy, leading to cancer- and drug-free states in patients with u-HCC undergoing Atez/Bev therapy. Moreover, surgery or RFA may be suitable for conversion therapy for cancer-free status.

Striking advances in systemic therapy for unresectable advanced hepatocellular carcinoma (HCC) have improved the average prognosis of patients with HCC. As a result, the guidelines for the treatment of HCC have changed significantly. However, various issues have emerged in clinical practice. First, there is no established biomarker that can predict response to systemic therapy. Second, there is no established treatment regimen after primary systemic therapy, including combined immunotherapy. Third, there is no established treatment regimen for intermediate-stage HCC. These points make the current guidelines ambiguous. In this review, we present the Japanese guidelines for the diagnosis and treatment of HCC based on the latest evidence; introduce various efforts mainly in Japanese real-life practice to update these guidelines; and present our perspectives on future guidelines.

BACKGROUND AND AIM: This study aimed to investigate whether telephone follow-up by clinical pharmacists for unresectable hepatocellular carcinoma (HCC) patients treated with lenvatinib (LEN) contributes to improved adherence and treatment duration for LEN. METHODS: This retrospective study enrolled 132 patients with HCC who were treated with LEN. The patients were classified into non-telephone follow-up (n = 32) or telephone follow-up groups (n = 100) [the latter group was further classified into family-pharmacist (FP) telephone follow-up (n = 18), or hospital family-pharmacist (HFP) telephone follow-up (n = 82) groups]. RESULTS: The progression-free survival (PFS) in the telephone follow-up group was significantly higher than that in the non-telephone follow-up group (PFS 6.1 months vs 3.7 months, P = 0.001, respectively). Although treatment duration was significantly longer in the telephone follow-up group than in the non-telephone follow-up group [median treatment duration: 10.4 months vs 4.1 months, P = 0.001, respectively.], no significant differences were noted between the HFP telephone follow-up group and FP telephone follow-up groups (10.3 months vs 13.3 months, P = 0.543). Self-interruption and adverse-event discontinuation in the HFP-telephone follow-up group were significantly lower than those in the FP-telephone and non-telephone groups (0% vs 11.1% vs 18.8%; P < 0.001, 25.6% vs 33.3% vs 53.1%; P = 0.022, respectively). CONCLUSIONS: Telephone follow-up contributes to prolonged treatment duration for LEN in patients with HCC treated. Moreover, telephone follow-up with an HFP may further improve treatment adherence.

BACKGROUND: Antiangiogenic tyrosine kinase inhibitors (TKIs) provide one of the few therapeutic options for effective treatment of hepatocellular carcinoma (HCC). However, patients with HCC often develop resistance toward antiangiogenic TKIs, and the underlying mechanisms are not understood. The aim of this study was to determine the mechanisms underlying antiangiogenic TKI resistance in HCC. METHODS: We used an unbiased proteomic approach to define proteins that were responsible for the resistance to antiangiogenic TKIs in HCC patients. We evaluated the prognosis, therapeutic response, and serum insulin-like growth factor-binding protein-1 (IGFBP-1) levels of 31 lenvatinib-treated HCC patients. Based on the array of results, a retrospective clinical study and preclinical experiments using mouse and human hepatoma cells were conducted. Additionally, in vivo genetic and pharmacological gain- and loss-of-function experiments were performed. RESULTS: In the patient cohort, IGFBP-1 was identified as the signaling molecule with the highest expression that was inversely associated with overall survival. Mechanistically, antiangiogenic TKI treatment markedly elevated tumor IGFBP-1 levels via the hypoxia-hypoxia inducible factor signaling. IGFBP-1 stimulated angiogenesis through activation of the integrin α5ß1-focal adhesion kinase pathway. Consequently, loss of IGFBP-1 and integrin α5ß1 by genetic and pharmacological approaches re-sensitized HCC to lenvatinib treatment. CONCLUSIONS: Together, our data shed light on mechanisms underlying acquired resistance of HCC to antiangiogenic TKIs. Antiangiogenic TKIs induced an increase of tumor IGFBP-1, which promoted angiogenesis through activating the IGFBP-1-integrin α5ß1 pathway. These data bolster the application of a new therapeutic concept by combining antiangiogenic TKIs with IGFBP-1 inhibitors.

AIM: Lenvatinib is used to treat advanced hepatocellular carcinoma (HCC). Metabolic dysfunction-associated fatty liver disease (MAFLD) is becoming a major etiology of HCC. We aimed to evaluate the impact of MAFLD on the efficacy of lenvatinib. METHODS: We enrolled 320 patients with HCC who were treated with lenvatinib. All patients were classified into the MAFLD (n = 155) and non-MAFLD (n = 165) groups. Independent factors for overall survival (OS) were analyzed. In the stratification analysis, HCC was categorized as non-viral (n = 115) or viral HCC (n = 205). RESULTS: The OS rate was significantly higher in the MAFLD group than in the non-MAFLD group (median 21.1 vs. 15.1 months, p = 0.002). Multivariate analysis demonstrated that, in addition to albumin-bilirubin grade and Barcelona Clinic Liver Cancer stage, MAFLD was identified as an independent factor for OS (HR 0.722, 95% CI 0.539-0.966, p = 0.028). In the stratification analysis, the OS rate was significantly higher in the MAFLD group than in the non-MAFLD group among patients with non-viral HCC (median 21.1 vs. 15.1 months, p = 0.002), but not in patients with viral HCC. Furthermore, MAFLD was an independent negative risk factor for OS in patients with non-viral HCC (HR 0.506, 95% CI 0.297-0.864, P < 0.01). However, MAFLD was not an independent factor for OS in patients with viral HCC. CONCLUSIONS: MAFLD was a beneficial factor for survival in patients with HCC treated with lenvatinib. Moreover, the better OS of the MAFLD group was more pronounced in patients with non-viral HCC. Lenvatinib may be a suitable agent for patients with non-viral HCC and MAFLD.
RESUMO
AIM: Few studies have reported the efficacy and safety of ramucirumab (RAM) after atezolizumab plus bevacizumab (Atezo/Beva) treatment and the overall associated outcomes. Thus, we aimed to evaluate the therapeutic effects and safety of RAM post-treatment with Atezo/Beva. METHODS: This retrospective study enrolled 46 patients with unresectable hepatocellular carcinoma who were treated with RAM. The patients were classified into the RAM administered following Atezo/Beva failure (n = 12) or RAM administered following other drug failure (n = 34) groups. Progression-free survival (PFS), overall survival (OS), and adverse event (AE) rates were assessed. RESULTS: There were significant differences in the objective response rates and disease control rates between the RAM administered following Atezo/Beva and RAM administered following others groups (objective response rate 33.3%. vs. 0.0%, p = 0.001; disease control rate 83.3% vs. 32.3, p = 0.001). Although there was no significant difference in the OS rates, the median PFS rates in the RAM administered following Atezo/Beva group was significantly higher than in the RAM administered following others group (PFS 3.9 months. vs. 1.9 months, p = 0.047). The AE rates were comparable between the two groups; ascites was the most common AE (45.6%). Using decision tree analysis, the presence of splenomegaly and body mass index (BMI) < 19.8 were the first and second splitting variables for RAM-related ascites, respectively. CONCLUSIONS: The therapeutic effect of RAM increased in patients with Atezo/Beva failure. Patients with splenomegaly and low BMI should be monitored for ascites during RAM treatment.
RESUMO
This study aimed to investigate the clinical characteristics of patients with unresectable hepatocellular carcinoma (HCC), who were eligible for sequential systemic therapy. We evaluated 365 patients with HCC who underwent systemic therapy after 2017. The overall survival (OS) was 13.7 months, 19.2 months, and 35.6 months in the first-line, second-line, and third-line or later therapy groups, respectively. Multivariate analysis revealed that the modified-albumin-bilirubin (m-ALBI) grade, macrovascular invasion, extrahepatic spread, discontinuation due to adverse events (AEs), and sequential therapy were independent factors for OS. At the end of each therapy, the ALBI score was significantly worse among patients with discontinuation due to AEs than among those without. The conversion rate to second-line and third-line therapy among patients with discontinuation due to AEs was significantly lower than that among patients without (30.4% vs. 69.2%, p < 0.001; 6.7% vs. 58.3%; p < 0.001, respectively). In the decision tree analysis, m-ALBI grade 1 or 2a and non-advanced age were selected splitting variables, respectively, for sequential systemic therapy. In conclusion, sequential therapy prolonged the OS of unresectable HCC. Additionally, good hepatic function and non-advanced age were clinically eligible characteristics for sequential systemic therapy.

This study aimed to evaluate the correlation between adverse events (AEs) and overall survival (OS) in patients with unresectable hepatocellular carcinoma treated with atezolizumab plus bevacizumab (atezo/beva). This was a multicenter study in which 130 patients were enrolled. Hypertension and skin disorders had a significant correlation with longer survival (median survival time (MST): not reached vs. 14.3 months and not reached vs. 14.8 months, p = 0.001 and p = 0.047, respectively). In contrast, liver injuries were significantly correlated with shorter survival (MST: 14.7 months vs. not reached, p = 0.036), and the median development time was 21 days. In a logistic regression analysis, fatigue ≥ grade 2, liver injury ≥ grade 3, and modified albumin-bilirubin grade 2b were identified as independent factors for discontinuation due to AEs. The OS in the no discontinuation due to AE group was significantly longer than that in the discontinuation due to AEs group (MST not reached vs. 11.2 months, p = 0.001). We concluded that the development of liver injury was a negative factor for OS and that we should be vigilant in monitoring AE during atezo/beva treatments.
RESUMO
Recently, a combined regimen of atezolizumab and bevacizumab (AB) treatment has been approved as a first-line treatment in patients with advanced hepatocellular carcinoma (HCC), contributing to prolonged survival. However, we often encounter cases where treatment must be discontinued due to the occurrence of adverse events. One of these events, which is often fatal, is gastrointestinal bleeding. To clarify the clinical effects of gastrointestinal bleeding after AB treatment, we evaluated patients with HCC who were treated with AB at our institution. Of the 105 patients, five treated with AB developed gastrointestinal bleeding, necessitating treatment discontinuation. Additionally, we encountered two cases where exacerbation of varicose veins was observed, and AB therapy could be continued by preventive treatment of varices. In conclusion, an appropriate follow-up is required during treatment with AB to prevent possible exacerbation of varicose veins.
RESUMO
Phytohormones are produced by plants and play central roles in interactions with pathogenic and beneficial microbes as well as plant growth and development. Each phytohormone pathway consists of its biosynthesis, transport, perception, and signaling and is intertwined with each other at various levels to form phytohormone networks in plants. Different kinds of microbes also produce phytohormones that exert physiological roles within microbes and manipulate phytohormone networks in plants by using phytohormones, their mimics, and proteinaceous effectors. In turn, plant-derived phytohormones can directly or indirectly through plant signaling networks affect microbial metabolism and community assembly. Therefore, phytohormone networks in plants and microbes are connected through plant and microbial phytohormones and other molecules to form inter-organismal phytohormone networks. In this review, we summarize recent progress on molecular mechanisms of inter-organismal phytohormone networks and discuss future steps necessary for advancing our understanding of phytohormone networks.

In 2013 and 2014, the development of microcatheters with balloons for the 4-Fr system and new embolization materials provided various options for transarterial chemoembolization (TACE), expanding the range of treatment strategies. At our hospital, balloon-occluded TACE (B-TACE), conventional TACE (C-TACE), and drug-eluting bead TACE (DEB-TACE) have been actively performed for hepatocellular carcinoma (HCC). This study compared the local recurrence-free (LRF) periods of nodules with complete necrosis (TE4) obtained using each treatment method by extracting the nodules evaluated as complete response by the modified Response Evaluation Criteria in Solid Tumors. We performed 580 TACE procedures between June 2013 and April 2019. Among them, 58 HCC nodules in 43 patients, 33 nodules in 30 patients, and 45 nodules in 25 patients were evaluated as having complete necrosis after C-TACE, DEB-TACE, and B-TACE, respectively. The time to local recurrence for each nodule was defined as the LRF period, and the quality of TE4 for each TACE was examined. Factors related to overall survival and the LRF period were determined by univariate and multivariate analyses, and overall survival and the LRF period were analyzed using the Kaplan-Meier method. Multivariate analysis of the LRF period showed that B-TACE was an independent factor. The median LRF periods were 39.3, 13, and 9.1 months for B-TACE, C-TACE, and DEB-TACE, respectively. Moreover, B-TACE had a significantly longer LRF period than C-TACE and DEB-TACE. Conclusion: There was no significant difference between C-TACE and DEB-TACE. The LRF period of nodules with TE4 was the longest with B-TACE, suggesting that B-TACE should be used to achieve a radical cure in patients with HCC.

It remains unclear whether hepatocellular carcinoma (HCC) recurrence in hepatitis C virus (HCV)-infected patients can be suppressed by the elimination of the virus using direct-acting antivirals (DAAs) after radical HCC treatment. We evaluated the sustained inhibitory effect of DAAs on HCC recurrence after curative treatment. This multicenter retrospective study included 190 HCV-positive patients after radical treatment for early-stage HCC. Patients were classified into the DAA treatment group (n = 70) and the non-DAA treatment group (n = 120) after HCC treatment. After propensity score matching (PSM), 112 patients were assessed for first and second recurrences using the Kaplan-Meier method and analyzed using a log-rank test. The first recurrence rates at 1 and 3 years were 3.6% and 42.1% in the DAA treatment group and 21.7% and 61.9% in the non-DAA treatment group, respectively (p = 0.0026). Among 85 patients who received radical treatment, the second recurrence rate at 3 years was 2.2% in the DAA treatment group and 33.9% in the non-DAA treatment group (p = 0.0128). In HCV-positive patients with early-stage HCC, the first and second recurrences were suppressed by DAA therapy after radical treatment, suggesting that the inhibitory effect of DAA therapy on HCC recurrence was sustained.
RESUMO
Chemolipiodolization (CL) is less invasive than transarterial chemoembolization (TACE) for managing hepatocellular carcinoma (HCC) because it helps avoid embolization. However, the treatment outcomes of percutaneous radiofrequency ablation (PRFA) with or without CL for HCC remain unclear. Herein, we compared the prognostic factors for overall survival (OS) following PRFA with or without CL for HCC using propensity-score-matched analysis. A total of 221 patients with HCC treated with PRFA at Saga Central Hospital between April 2004 and October 2020, with or without CL, were enrolled. No significant difference was observed in OS between PRFA with and without CL cohorts (median survival time (MST): 4.5 vs. 5.4 years; p = 0.0806). To reduce the confounding effects of 12 variables, we performed propensity-score-matched analysis to match patients treated with PRFA with or without CL. No significant difference was observed in OS between PRFA with and without CL cohorts (MST: 4.0 vs. 3.6 years; p = 0.5474). After stratification according to tumor size, no significant difference was observed in OS for patients with tumor size ≥20 mm between PRFA with and without CL cohorts (MST: 3.5 vs. 3.4 years; p = 0.8236). PRFA with CL was not a significant prognostic factor in both univariate and multivariate analyses (p = 0.5477 and 0.9600, respectively). Our findings suggest that PRFA with CL does not demonstrate more favorable prognosis than PRFA without CL for HCC, regardless of tumor size.
