Outcomes of Patients with Child-Pugh B and Unresectable Hepatocellular Carcinoma Undergoing First-Line Systemic Treatment with Sorafenib, Lenvatinib, or Atezolizumab Plus Bevacizumab.

INTRODUCTION: Systemic therapy is recommended for patients with Child-Pugh A in hepatocellular carcinoma (HCC). We analyzed the outcomes of a cohort of patients with HCC who received either sorafenib (Sor), lenvatinib (Len) or atezolizumab plus bevacizumab (Atezo + Bev) as first-line systemic therapy for HCC, with the aim of identifying prognostic factors for survival. METHODS: A total of 825 patients with advanced HCC and Child-Pugh A or B received either Sor, Len or Atezo + Bev as first-line systemic therapy. Liver function was assessed according to the Child-Pugh score and the modified albumin-bilirubin (mALBI) grade. RESULTS: Prognosis was analyzed according to liver function such as Child-Pugh classifications, scores, and mALBI grades that worsened with a decline in liver function (p <0.001 for all). A Child-Pugh score of 7 was a factor significantly associated with OS. In patients with a Child-Pugh score of 7, an mALBI grade of 3 was an independent predictor of OS. In Child-Pugh B patients with HCC, receiving Atezo + Bev was identified as a factor associated with PFS. CONCLUSION: Determining the hepatic reserve of patients with unresectable HCC might be useful for identifying patents suitable for systemic treatment for HCC. Atezo + Bev might prolong the PFS of patients with a Child-Pugh score of 7.

The Analysis of Muscle Volume Measured by Bioelectrical Impedance in Patients with Hepatocellular Carcinoma Treated with First-Line Atezolizumab plus Bevacizumab Combination Therapy or First-Line Lenvatinib.

INTRODUCTION: Measurements of body composition, such as the skeletal muscle index (SMI), are useful for predicting prognosis in hepatocellular carcinoma (HCC). This study aimed to analyze the relationship between skeletal muscle changes during therapy with atezolizumab plus bevacizumab (Atezo + Beva) or lenvatinib (Len) and the association between SMI and prognosis. METHODS: Patients with advanced HCC and Child-Pugh A status received Atezo + Beva or Len as first-line systemic chemotherapy. We assessed prognosis and body composition obtained by bioelectrical impedance analysis. RESULTS: A total of 109 patients received treatment (Atezo + Beva, n = 47; Len, n = 62). During treatment, the arm SMI was reduced in the Len group and maintained in the Atezo + Beva group. The extracellular water to total body water ratio (ECW/TBW) increased significantly in both groups during treatment. In the Atezo + Beva group, no factor was associated with prognosis. Multivariate analysis showed that in the Len group, the arm SMI (hazard ratio [HR], 0.5; 95% CI: 0.26-0.89; p = 0.02), ECW/TBW (HR: 2.7; 95% CI: 1.21-6.01; p = 0.01), and Child-Pugh score (HR: 2.3; 95% CI: 1.31-6.13; p = 0.004) were associated with progression-free survival. CONCLUSION: Assessing body composition with BIA before Atezo + Beva and Len treatment may be useful.

Enhancement of the mechanical properties of organic-inorganic hybrid elastomers by introducing movable and reversible crosslinks.

Organic-inorganic materials have been widely utilized in various fields as multifunctional materials. Poly(dimethyl siloxane) (PDMS), a typical inorganic polymer, has industrially appealing functions, such as transparency, biocompatibility, and gas permeability; however, it has poor mechanical properties. We incorporated organic-inorganic hybrid elastomers (PDMS-γCD-AAl⊃P(EA-HEMA) (x)) with movable crosslinks, and we utilized hydrogen bonds as reversible crosslinks. The organic polymer poly ethyl acrylate-r-hydroxy ethyl methacrylate (P(EA-HEMA)) penetrated the cavity of triacetylated γ-cyclodextrin (γCD), which was introduced into the side chains of PDMS, and it compounded with PDMS at the nanoscale. Structural studies involving visual and X-ray scattering measurements revealed that movable crosslinks improved the compatibility levels of PDMS and acrylate copolymers. However, macroscopic phase separation occurred when the number of reversible crosslinks increased. Furthermore, studies on the mobility levels of acrylate copolymers and movable crosslinks indicated that the relaxation behaviour of PDMS-γCD-AAl⊃P(EA-HEMA) (x) changed with changing numbers of reversible crosslinks. Introducing reversible crosslinks improved the Young's modulus and toughness values. The movable and reversible crosslinks between the organic and inorganic polymers contributed to the high elongation properties. The design of PDMS-γCD-AAl⊃P(EA-HEMA) (x) incorporated cooperatively movable and reversible crosslinks to achieve high compatibility of immiscible polymers and to control the mechanical properties.

Interfacial Selective Study on the Gelation Behavior of Aqueous Methylcellulose Solution via a Quartz Crystal Microbalance.

It is important to understand the interfacial structure and physical properties of a polymer material to improve its function. In this study, we used a quartz crystal microbalance (QCM) and neutron reflectivity (NR) measurements to evaluate the viscoelasticity and structure of an aqueous methylcellulose solution near the gold interface. The apparent shear modulus, which was calculated from the complex frequency, was used to assess gelation behavior. The apparent shear modulus determined via the QCM suggested high-frequency rheological properties that reflected the relaxation of skeletal stretching and rotational motion of polymer segments, as well as cooperative motion of the various functional groups. The gelation temperature was found to be lowered at the interface in comparison with that of the bulk. It is suggested that the QCM can evaluate the shear modulus accompanying the gelation near the interface. The interfacial segregation on the gold substrate caused by the surface free energy and long-range van der Waals interaction was observed from NR measurements.

Evaluation of cold snare polypectomy for small pedunculated (Ip) polyps with thin stalks: a prospective clinical feasibility study.

BACKGROUND: Although the use of cold snare polypectomy (CSP) has spread rapidly, no prospective studies evaluating the safety of CSP for pedunculated (Ip) polyps have been carried out. AIM: We performed this study to provide an accurate evaluation of the safety of CSP for Ip polyps. METHODS: This is a prospective study (UMIN000035687). From January 2019 to February 2021, the safety of CSP for use on Ip polyps <10 mm with thin stalks was evaluated at our hospital. The primary outcome measure was the incidence of bleeding (delayed post-polypectomy bleeding (DPPB) and immediate bleeding). RESULTS: During the study period, 89 consecutive patients (including 92 colonoscopies and 114 polyps) were prospectively enrolled. The en-bloc resection rate was 100%. The rate of DPPB after CSP was 0%, however, DPPB after conversion to HSP occurred in 1 case (33.3% (1/3)). The rate of immediate bleeding during CSP was 28.9% (33/114). Polyps with diameters ≥6 mm (OR (95% CI): 2.77 (1.041-7.376); p = .041) were extracted as independent risk factors for immediate bleeding during CSP for Ip polyps. In all, 104 (91.2%) polyps were low-grade adenomas, and the percentage of cases with negative pathological margins was 96.5% (110/114). CONCLUSIONS: CSP for Ip polyps was safe and had good outcomes. We believe that Ip polyps could be included as an indication for CSP, and that CSP may become the next step in the 'cold revolution.' To confirm our results and verify CSP's inclusion in future guidelines, prospective, randomized studies are necessary.

Efficacy and safety of chemoradiation therapy using one-shot cisplatin via hepatic arterial infusion for advanced hepatocellular carcinoma with major macrovascular invasion: a single-arm retrospective cohort study.

BACKGROUND: Patients with hepatocellular carcinoma (HCC) and macrovascular invasion (MVI) who receive systemic chemotherapy have a poor prognosis. This study aimed to determine if one-shot cisplatin (CDDP) chemotherapy via hepatic arterial infusion (HAI) combined with radiation therapy (RT) prior to systemic chemotherapy could improve the outcomes of these patients. METHODS: This study consisted of 32 HCC patients with the following eligibility criteria: (i) portal vein invasion 3/4 and/or hepatic vein invasion 2/3; (ii) received one-shot CDDP via HAI; (iii) received RT for MVI, (iv) a Child-Pugh score ≤ 7; and (v) an Eastern Clinical Oncology Group Performance Status score of 0 or 1. To determine the therapeutic effect, we collected information on patient characteristics and took contrast-enhanced computed tomography at the start of the therapy and every 2 to 4 months after the start of therapy. We evaluated the overall response of the tumor and tumor thrombosis according to modified Response Evaluation Criteria in Solid Tumors. We assessed patient data using the Mann-Whitney U and Fisher exact tests and evaluated overall survival and progression-free survival using the log-rank test. RESULTS: The overall response rate at the first evaluation performed a median of 1.4 weeks after HAI was 16% for the main intrahepatic tumor and 59% for the MVI. The best responses were the same as those of the first-time responses. The duration of median survival was 8.6 months, and progression-free survival of the main intrahepatic tumor was 3.2 months. Predictive factors for overall survival were the relative tumor volume in the liver and the first therapeutic response of MVI. There were no severe adverse events or radiation-induced hepatic complications. CONCLUSIONS: One-shot CDDP via HAI and RT were well tolerated and showed immediate and favorable control of MVI. Thus, this combination shows potential as a bridging therapy to systemic chemotherapy.

Extracellular water to total body water ratio obtained by bioelectrical impedance analysis determines the dose intensity of lenvatinib for the treatment of patients with advanced hepatocellular carcinoma.

BACKGROUND AND AIM: The aim of this study was to identify the factors that contribute to the maintenance of relative dose intensity (RDI) of lenvatinib in hepatocellular carcinoma (HCC) patients. METHODS: Thirty-two patients with advanced HCC treated with lenvatinib were enrolled. We evaluated the relationship between maintenance of RDI and various clinical data, parameters obtained by body composition measurements with bioelectrical impedance analysis (BIA) and grip strength at the start of lenvatinib treatment. RESULTS: Multivariate analysis showed that only the extracellular water to total body water ratio (ECW/TBW) ≤ 0.400 at initiation of treatment was associated with RDI ≥ 50% (odds ratio, 6.94; 95% confidence interval [CI], 1.00-48.00; P = 0.049). When the RDI was compared between ECW/TBW ≤ 0.400 group and ECW/TBW > 0.400 group, the RDI was significantly higher in the ECW/TBW ≤ 0.400 group at each of 0-4W, 4-6W, and 6-8W points. The P value at each point was 0.003, 0.003, and 0.005, respectively. On the other hand, multivariate analysis showed that only the ECW/TBW ≤ 0.400 at initiation of treatment was associated with the extension of duration until reduction or withdrawal of lenvatinib (hazard ratio, 4.86; 95% CI, 1.52-15.50; P = 0.007). CONCLUSION: The extracellular water to total body water ratio, a parameter of body composition measurement by BIA, was significantly associated with the maintenance of RDI and the duration until reduction or withdrawal of lenvatinib in HCC patients. In addition to standard predictors such as Child-Pugh score and modified albumin-bilirubin grade that have been used to date, ECW/TBW might be a new predictor of RDI in HCC patients treated with lenvatinib.

Trends in Hepatic Functional Reserve of Patients with Hepatocellular Carcinoma Treated with Tyrosine Kinase Inhibitors.

OBJECTIVE: Functional hepatic reserve is important when considering sequential tyrosine kinase inhibitor (TKI) therapy for patients with advanced hepatocellular carcinoma (HCC). We assessed albumin-bilirubin (ALBI) score and Child-Pugh class as indices of liver function during sorafenib and lenvatinib treatment. METHODS: A total of 212 patients with advanced HCC and Child-Pugh class A status who initiated TKI treatment at our hospital were enrolled in this retrospective cohort study. A total of 74 of the 212 patients underwent blood testing before starting sorafenib treatment and every 2 months after treatment initiation. RESULTS: In 74 patients, the median ALBI score before TKI treatment was -2.53, and after 2, 4, and 6 months it was -2.45, -2.44, and -2.36, respectively. ALBI scores tended to increase during TKI therapy. Among patients who experienced a time to progression ≤3.8 months, ALBI scores had increased 2 months after treatment initiation, and at 4 and 6 months, significant differences were observed (p < 0.01). In all 212 patients, during first-line TKI treatment, the Child-Pugh class deteriorated to B or C in 72.2% of the patients, and the median time to deterioration was 3.9 months. The factors in hepatic reserve deterioration were serum albumin ≤3.8 g/dL and the presence of macroscopic vascular invasion. The hepatic reserve of 68.0% of the patients with deterioration of liver function recovered to Child-Pugh class A following dose reduction, drug withdrawal, or treatment intended for recovery of liver function. CONCLUSION: ALBI scores deteriorate in patients treated with TKIs, suggesting that tumor progression induces these changes.

Analysis of Post-Progression Survival in Patients with Unresectable Hepatocellular Carcinoma Treated with Lenvatinib.

BACKGROUND: Although a strong antitumor effect of lenvatinib (LEN) has been noted for patients with unresectable hepatocellular carcinoma (HCC), there are still no reports on the prognosis for patients with disease progression after first-line LEN therapy. METHODS: Patients (n = 141) with unresectable HCC, Child-Pugh class A liver function, and an Eastern Cooperative Oncology Group performance status (ECOG-PS) of 0 or 1 who were treated with LEN from March 2018 to December 2019 were enrolled. RESULTS: One hundred and five patients were treated with LEN as first-line therapy, 53 of whom had progressive disease (PD) at the radiological evaluation. Among the 53 patients with PD, there were 27 candidates for second-line therapy, who had Child-Pugh class A liver function and an ECOG-PS of 0 or 1 at progression. After progression on first-line LEN, 28 patients were treated with a molecular targeted agent (MTA) as second-line therapy (sorafenib: n = 26; ramucirumab: n = 2). Multivariate analysis identified modified albumin-bilirubin grade 1 or 2a at LEN initiation (odds ratio 5.18, 95% confidence interval [CI] 1.465-18.31, p = 0.011) as a significant and independent factor for candidates. The median post-progression survival after PD on first-line LEN was 8.3 months. Cox hazard multivariate analysis showed that a low alpha-fetoprotein level (<400 ng/mL; hazard ratio [HR] 0.297, 95% CI 0.099-0.886, p = 0.003), a relative tumor volume <50% at the time of progression (HR 0.204, 95% CI 0.07-0.592, p = 0.03), and switching to MTAs as second-line treatment after LEN (HR 0.299, 95% CI 0.12-0.746, p = 0.01) were significant prognostic factors. CONCLUSION: Among patients with PD on first-line LEN, good liver function at introduction of LEN was an important and favorable factor related to eligibility for second-line therapy. In addition, post-progression treatment with MTAs could improve the prognosis for patients who had been treated with first-line LEN.

Incidence of microsatellite instability-high hepatocellular carcinoma among Japanese patients and response to pembrolizumab.

AIM: Pembrolizumab has been quickly approved in many countries for the treatment of patients with unresectable or metastatic, microsatellite instability-high (MSI-H) solid tumors, which have progressed following previous treatment and who have no satisfactory alternative treatment options. We aimed to determine the incidence of MSI-H tumors in Japanese patients with advanced hepatocellular carcinoma (HCC). METHODS: We investigated the incidence of MSI-H tumors in 82 consecutive Japanese patients with unresectable HCC that had progressed after standard of care treatment. Using a companion diagnostic sequencing kit (polymerase chain reaction analysis of five microsatellite markers: BAT25, BAT26, NR21, NR24 and MONO27), we analyzed 49 biopsy specimens and 33 resection specimens. Responses to pembrolizumab were assessed with the modified Response Evaluation Criteria in Solid Tumors. RESULTS: MSI-H tumors were found in only two patients (2.4%), in whom all five markers showed slight shortening. One patient had a complete response to pembrolizumab for over 10 months, and the other was a non-responder. CONCLUSIONS: MSI-H tumor status was found in only two of 82 (2.4%) Japanese patients with advanced HCC, one of whom had a complete response to pembrolizumab. Thus, MSI status should be assessed in patients with HCC who progress after standard of care treatment.

A novel human pain insensitivity disorder caused by a point mutation in ZFHX2.

Chronic pain is a major global public health issue causing a severe impact on both the quality of life for sufferers and the wider economy. Despite the significant clinical burden, little progress has been made in terms of therapeutic development. A unique approach to identifying new human-validated analgesic drug targets is to study rare families with inherited pain insensitivity. Here we have analysed an otherwise normal family where six affected individuals display a pain insensitive phenotype that is characterized by hyposensitivity to noxious heat and painless bone fractures. This autosomal dominant disorder is found in three generations and is not associated with a peripheral neuropathy. A novel point mutation in ZFHX2, encoding a putative transcription factor expressed in small diameter sensory neurons, was identified by whole exome sequencing that segregates with the pain insensitivity. The mutation is predicted to change an evolutionarily highly conserved arginine residue 1913 to a lysine within a homeodomain. Bacterial artificial chromosome (BAC) transgenic mice bearing the orthologous murine p.R1907K mutation, as well as Zfhx2 null mutant mice, have significant deficits in pain sensitivity. Gene expression analyses in dorsal root ganglia from mutant and wild-type mice show altered expression of genes implicated in peripheral pain mechanisms. The ZFHX2 variant and downstream regulated genes associated with a human pain-insensitive phenotype are therefore potential novel targets for the development of new analgesic drugs.awx326media15680039660001.

Improvement in Cohesive Properties of Adhesion Systems Using Movable Cross-Linked Materials with Stress Relaxation Properties.

A strong, tough, and stable adhesion system used in various environments must be developed. A long-lasting adhesion system should effectively perform in the following five aspects: adhesion strength, toughness, energy dissipation property, self-restoration property, and creep resistance property. However, these properties are difficult to balance using conventional adhesives. Here, a new topological adhesion system using single-movable cross-network (SC) materials [SC(DMAAm) Adh] was designed. 3-(Trimethoxysilyl) propyl acrylate was used as the anchor, N,N-dimethyl acrylamide (DMAAm) was used as the main chain monomer, and γ-cyclodextrin (γ-CD) units acted as movable cross-links. The movable cross-links provided SC(DMAAm) Adh with energy dissipation properties, thereby improving its toughness. The γ-CD units also acted as bulky stoppers that provided a high adhesion strength and self-restoration properties. Moreover, the combination of the movable cross-links and bulky stoppers provided creep resistance to SC(DMAAm) Adh. The performance of the adhesion systems under different mobilities of the polymer chains was examined by adjusting the water content. In proper water-containing states, all mechanical properties of SC(DMAAm) Adh were better than those of the adhesion systems using homopolymers [P(DMAAm) Adh] and polymers with covalent cross-linking points [CP(DMAAm) Adh].

Recyclable Tough Adhesive Sheets with Movable Cross-Links for Sustainable Use.

Acrylic adhesive sheets have been used for many applications, from popular seal materials to high-end electrical devices. One of the basic and critical design features of adhesives is effective covalent cross-linking for superior adhesive properties. On the other hand, covalent cross-linking prevents reuse or recycling of the adhesive. This makes the adhesive sheets insoluble and poorly workable. For development of sustainable adhesives, we investigated the adhesive sheets based on acrylic elastomers with "Movable Cross-links" (M-PEA-CD (0.5)) copolymerized with 0.5 mol % cyclodextrin monomers. The peel strength and creep resistance of M-PEA-CD (0.5) were greater than those of adhesives (N-PEA) without any cross-links. M-PEA-CD (0.5) was recyclable via dissolution in ethyl acetate. Furthermore, the recycled M-PEA-CD (0.5) from solution exhibited the same adhesion properties as virgin M-PEA-CD (0.5). Spectroscopic and mechanical measurements indicated that topological cross-linking with Cyclodextrin (CD) moieties generated novel recyclable adhesive sheets without restricting the polymer main chains, unlike covalent cross-linking (CC-PEA). The movable cross-links were maintained in both the solid state and in solution, which allowed recycling of the elastomer via simple methods.

Impact of MAFLD criteria on postoperative recurrence of non-B, non-C HCC.

BACKGROUND: This study aimed to clarify the population in whom the presence of metabolic dysfunction-associated fatty liver disease (MAFLD) especially contributes to recurrence after liver resection for non-B, non-C hepatocellular carcinoma (NBNC-HCC). METHODS: Of the 199 patients who underwent liver resection for NBNC-HCC, those who exceeded Milan criteria and with pathologically proven vascular invasion, intrahepatic metastasis, and positive resection margins were excluded, and the remaining 94 were eligible for this study. We explored factors contributing to postoperative recurrence in populations with and without advanced liver fibrosis. RESULTS: Independent factors contributing to postoperative recurrence in the study population were male sex ( P  = 0.023) and presence of type 2 diabetes (DM) ( P  = 0.006) and advanced liver fibrosis ( P  < 0.001). Factors in cases with advanced liver fibrosis (n = 43) were non-overweight ( P  = 0.02), type 2 DM ( P  = 0.006), and preoperative alpha-fetoprotein level of 8.2 ng/ml or higher ( P  = 0.021). In cases without advanced liver fibrosis (n = 51), only presence of all three MAFLD criteria was related to recurrence. CONCLUSION: Liver fibrosis is a strong factor contributing to postoperative recurrence of NBNC-HCC, as previously reported. In patients with advanced liver fibrosis, presence of type 2 DM was the only factor associated with recurrence among MAFLD criteria. On the other hand, in patients without advanced liver fibrosis, the combination of all MAFLD criteria, rather than a specific criterion alone, contributed to recurrence. MAFLD criteria were found to have utility as predictors of postoperative recurrence in NBNC-HCC.

Efficacy and safety of atezolizumab plus bevacizumab in patients with portal hypertension for unresectable hepatocellular carcinoma.

AIM: Atezolizumab plus bevacizumab combination therapy (Atezo + Beva) is used as the first-line therapy for unresectable hepatocellular carcinoma (u-HCC). Serious adverse events (AEs), including rupture of esophagogastric varices, have been seen during treatment. Therefore, the relationships of efficacy, safety, and portal hypertension (PH) were analyzed. METHODS: A total of 146 patients with u-HCC and Child-Pugh Scores of 5-7 received Atezo + Beva. Prophylactic treatment for varices was performed for patients with the risk of rupture of varices before the start of Atezo + Beva. A propensity score-matched cohort was created to minimize the risk of potential confounders. Efficacy was assessed in 41 propensity score-matched pairs. AEs were assessed between patients without PH (n = 80) and with PH (n = 66). RESULTS: In patients without PH and with PH, median overall survival was 18.4 months and 18.8 months (p = 0.71), and median progression-free survival was 8.6 months and 5.8 months (p = 0.92), respectively. On the best radiological response evaluation for Response Evaluation Criteria in Solid Tumors, the objective response rate was 31.7% and 26.8% (p = 0.81), respectively. Variceal rupture occurred in three patients with PH, but there were no significant differences in the occurrence of variceal rupture (p = 0.090) and Grade 3-4 AEs between patients without and with PH. CONCLUSIONS: No significant differences in efficacy and safety were observed with PH. Prophylactic treatment for varices before the start of Atezo + Beva would allow treatment to continue relatively safely.

The indirect corticopontine pathway relays perioral sensory signals to the cerebellum via the mesodiencephalic junction.

In the cerebro-cerebellar loop, outputs from the cerebral cortex are thought to be transmitted via monosynaptic corticopontine gray (PG) pathways and subsequently relayed to the cerebellum. However, it is unclear whether this pathway is used constitutively for cerebro-cerebellar transduction. We examined perioral sensory pathways by unit recording from Purkinje cells in ketamine/xylazine-anesthetized mice. Infraorbital nerve stimulations enhanced simple spikes (SSs) with short and long latencies (first and second peaks), followed by SS inhibition. The second peak and SS inhibition were suppressed by muscimol (a GABAA agonist) injections into not only the PG but also the mesodiencephalic junction (MDJ). The pathway from the secondary somatosensory area (SII) to the MDJ, but not the cortico-PG pathway, transmitted the second peak signals. SS inhibition was processed in the SII and primary motor area. Thus, the indirect cortico-PG pathway, via the MDJ, is recruited for perioral sensory transduction.

Sodium-glucose cotransporter-2 inhibitors improve FibroScan-aspartate aminotransferase scores in patients with nonalcoholic fatty liver disease complicated by type 2 diabetes.

BACKGROUND AND AIM: Nonalcoholic fatty liver disease (NAFLD) is a chronic liver disease caused by excessive lipid accumulation in the liver, and its global incidence is increasing. Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are oral antidiabetes drugs that promote glucose excretion into the urine and have been reported to exert therapeutic effects in NAFLD, but liver stiffness measurements (LSMs) determined by transient elastography are inconsistent. In addition, the effects of SGLT2is on the FibroScan-aspartate aminotransferase (FAST) scores have not been reported. We evaluated the effect of SGLT2is on patients with NAFLD complicated by type 2 diabetes using biochemical tests, transient elastography, and FAST scores. METHODS: Fifty-two patients with type 2 diabetes complicated by NAFLD who started SGLT2i treatment between 2014 and 2020 at our hospital were selected from the database. Pre- and post-treatment serum parameters, transient elastography, and FAST scores were compared. RESULTS: After 48 weeks of SGLT2i treatment, body weight, fasting blood glucose, hemoglobin A1c, AST, alanine aminotransferase, gamma-glutamyltransferase, uric acid, fibrosis-4 index, and AST to platelet ratio index improved. Median LSM decreased from 7.0 kPa to 6.2 kPa ( P  = 0.023) and the median controlled attenuation parameter decreased from 304 dB/m to 283 dB/m ( P  = 0.022). Median FAST score decreased from 0.40 to 0.22 ( P  < 0.001), and the number of cases with a cutoff value of ≥0.35 decreased from 15 to 6 ( P  = 0.001). CONCLUSION: SGLT2i use not only improves weight loss and blood glucose levels but also improves hepatic fibrosis by ameliorating hepatic steatosis and inflammation.

Effectiveness of Repeated Stereotactic Body Radiation Therapy for Hepatocellular Carcinoma-Consideration of the Locations of Target Lesions.

The present study retrospectively evaluated the efficacy of stereotactic body radiation therapy (SBRT), including repeated SBRT, for hepatocellular carcinoma. Participants comprised 220 HCC patients treated with SBRT in Hiroshima University Hospital between December 2008 and December 2021. Median overall survival (OS) and disease-free survival were 52 months (range, 45-64 months) and 17 months (range, 14-23 months), respectively. The 5-year local tumor recurrence rate was 3.4% (95% confidence interval (CI), 1.3-6.9%). Fifty-three patients underwent repeated SBRT (twice, 53 cases; three times, 10 cases; four times, 4 cases; five times, 1 case). Median interval between first and second SBRT was 20 months. Median OS from first SBRT was 76 months (95% CI, 50-102 months). Among patients with repeated SBRT, only one case showed local recurrence after second SBRT. Albumin-bilirubin score increased significantly from 6 to 12 months after repeated SBRT, both in the same segment and in remote segments, but the increase was not significant in the same segment. Only one case of grade 3 bile duct stricture was observed in patients who were treated with repeated SBRT. In conclusion, repeated SBRT provides good local control and a low risk of side effects.
