We updated the NPT by covering subjects aged 40-79 years and resetting the cut-off values. Thus, the updated NPT is an elderly and modern subject-compliant application. This update may improve the diagnostic ability of covert hepatic encephalopathy in contemporary cirrhotic patients.

BACKROUND: Not all patients with hepatocellular carcinoma (HCC) benefit from treatment with molecular targeted agents such as sorafenib. We investigated whether New-FP (fine-powder cisplatin and 5-fluorouracil), a hepatic arterial infusion chemotherapy regimen, is more favorable than sorafenib as an initial treatment for locally progressed HCC. METHODS: To avoid selection bias, we corrected the data from different facilities that did or did not perform New-FP therapy. In total, 1709 consecutive patients with HCC initially treated with New-FP or sorafenib; 1624 (New-FP, n = 644; sorafenib n = 980) were assessed. After propensity score matching (PSM), overall survival (OS) and prognostic factors were assessed (n = 344 each). Additionally, the patients were categorized into four groups: cohort-1 [(without macrovascular invasion (MVI) and extrahepatic spread (EHS)], cohort-2 (with MVI), cohort-3 (with EHS), and cohort-4 (with MVI and EHS) to clarify the efficacy of each treatment. RESULTS: New-FP prolonged OS than sorafenib after PSM (New-FP, 12 months; sorafenib, 7.9 months; p < 0.001). Sorafenib treatment, and severe MVI and EHS were poor prognostic factors. In the subgroup analyses, the OS was significantly longer the New-FP group in cohort-2. CONCLUSIONS: Local treatment using New-FP is a potentially superior initial treatment compared with sorafenib as a multidisciplinary treatment in locally progressed HCC without EHS.

The combination therapy of PEG-IFNα-2b and 5-FU for advanced ICC seems not to be worse than the results of the previous studies. Furthermore, most adverse effects are transient and well tolerated. Based on the present findings, this combination therapy may be useful for patients with advanced ICC as one of the therapeutic option.

A quantitative analysis of this phenomenon using MRS may contribute to an early and objective diagnosis of MHE.

Objective To prevent the development of overt hepatic encephalopathy, the early intervention for minimal hepatic encephalopathy (MHE) based on an accurate diagnosis is essential. This study investigated whether or not magnetic resonance diffusion kurtosis imaging (DKI) and diffusion tensor imaging (DTI) could detect brain microstructure abnormalities in MHE. The aim was to confirm whether or not brain microstructure abnormalities detected by magnetic resonance (MR) imaging could be used for the diagnosis of MHE. Methods Thirty-two subjects were prospectively examined with a 3-T MR scanner. Tract-based spatial statistics and region of interest analyses of diffusion imaging were performed to compare the mean kurtosis (MK), fractional anisotropy (FA), and mean diffusivity (MD) values between patients with and without minimal hepatic encephalopathy. The diagnostic performance for the detection of MHE was assessed with a receiver operating characteristic analysis. Results Ten subjects were diagnosed with MHE by neuropsychological testing. After the exclusion of unsuitable subjects, we analyzed 9 subjects with MHE and 14 without MHE. The patients with MHE had a reduced MK in the widespread white matter. We also found significant decreases in the MK in the caudate nucleus, putamen, globus pallidus, and/or thalamus in the subjects with MHE. The MK in the putamen showed the best diagnostic performance for differentiating the subjects with MHE from those without MHE (cut-off value, 0.74; sensitivity, 0.89; specificity, 0.86). Conclusion DKI detects changes in the cerebral white matter and basal ganglia regions of patients with MHE more sensitively than DTI. The MK values in the putamen can be a useful marker for diagnosing MHE from cirrhotic patients without MHE.

There is limited information regarding the oncological benefits of microwave ablation using ThermosphereTM technology for hepatocellular carcinoma. This study compared the overall survival and recurrence-free survival outcomes among patients with hepatocellular carcinoma after microwave ablation using ThermosphereTM technology and after radiofrequency ablation. Between December 2017 and August 2020, 410 patients with hepatocellular carcinoma (a single lesion that was ≤5 cm or ≤3 lesions that were ≤3 cm) underwent ablation at our institution. Propensity score matching identified 150 matched pairs of patients with well-balanced characteristics. The microwave ablation and radiofrequency ablation groups had similar overall survival rates at 1 year (99.3% vs. 98.2%) and at 2 years (88.4% vs. 87.5%) (p = 0.728), as well as similar recurrence-free survival rates at 1 year (81.1% vs. 76.2%) and at 2 years (60.5% vs. 62.1%) (p = 0.492). However, the microwave ablation group had a significantly lower mean number of total insertions (1.22 ± 0.49 vs. 1.59 ± 0.94; p < 0.0001). This retrospective study revealed no significant differences in the overall survival and recurrence-free survival outcomes after microwave ablation or radiofrequency ablation. However, we recommend microwave ablation for hepatocellular carcinoma tumors with a diameter of >2 cm based on the lower number of insertions.

A 69‐year‐old male complained of general fatigue and presented with elevation of liver enzymes without any cause of liver injury. We diagnosed him with hepatocellular drug‐induced liver injury (DILI). Liver stiffness, which was evaluated according to the shear wave velocity (SWV) using virtual touch tissue quantification, was serially observed during hospitalization. A fast SWV was noted on the date of admission, indicating a “hard” degree of liver stiffness. The SWV gradually decreased until the 20th hospital day. However, the patient's liver enzymes again became elevated on the 20th hospital day, and the SWV simultaneously increased in association with a rise in the total bilirubin level. The laboratory data for the second peak of the SWV indicated mixed‐type DILI; therefore, the patient's pathological state transitioned from the hepatocellular type to the mixed type. A liver biopsy performed before discharge revealed a state of recovery from acute inflammation without fibrotic changes. We conclude that the second peak of the SWV may be affected by the presence of intrahepatic cholestasis. We herein report the occurrence of bimodal peaks of liver stiffness in a patient with DILI. In such cases, each peak of liver stiffness may be the result of a different pathological mechanism, namely acute inflammation versus acute intrahepatic cholestasis. Although the detailed mechanisms underlying the development of liver stiffness due to intrahepatic cholestasis remain unclear, this case presented a limitation of virtual touch tissue quantification for evaluation of liver stiffness as fibrosis marker in the liver with intrahepatic cholestasis.
