Background
The effects of direct-acting antivirals (DAAs) on survival and recurrence rates after curative hepatocellular carcinoma (HCC) treatment in patients with hepatitis C virus (HCV) infection ...remain controversial.
Methods
This retrospective, multicenter study involved Child–Pugh class A patients within the Milan criteria who had a first diagnosis of HCC and survived 6 months or longer after undergoing hepatectomy or radiofrequency ablation (RFA). The DAA-treated group (DAA group) included 56 patients, and the DAA-untreated group (untreated group) included 261 patients. The study was conducted using the propensity score-matched (1:2) DAA group and untreated group, 56 and 112 patients, respectively.
Results
The survival rate at 48 months in the DAA group and the untreated group was 91.0% and 68.7%, respectively, showing significantly better survival in the DAA group (HR: 0.33; 95% CI 0.13–0.84;
p
= 0.021). The recurrence rate at 48 months was 36.7% and 66.7%, respectively, showing a significantly lower recurrence rate in the DAA group (HR, 0.46; 95% CI 0.27–0.77;
p
= 0.003). The median albumin–bilirubin (ALBI) score at 3 years post-HCC treatment was − 2.84 in the DAA group and − 2.34 in the untreated group. The ALBI score showed a significant improvement from baseline to 3 years post-HCC treatment (
p
= 0.001), whereas that in the untreated group showed a significant decline (
p
= 0.040).
Conclusions
DAAs after HCC treatment prevents deterioration of hepatic functional reserve and significantly improves both recurrence and survival rates.
Aim
The present study has developed and evaluated the effectiveness of a new echo attenuation measurement function combined with an ultrasonic diagnostic system for the accurate diagnosis of liver ...steatosis.
Methods
A multicenter prospective study involving patients with chronic hepatitis was carried out. All patients underwent liver biopsy, and attenuation coefficient (ATT) was measured on the same day. The fat area (%) of biopsy specimens was quantitatively evaluated. Correlations between ATT, steatosis grade, and fat area were evaluated.
Results
A total of 351 patients were enrolled in this study. The median values of fat area for steatosis grades S0, S1, S2, and S3 were 0.6%, 3.2%, 6.4%, and 15.5%, respectively. A significant correlation was found between fat area and steatosis grade (P < 0.001). Similarly, the median values of ATT for steatosis grades S0, S1, S2, and S3 were 0.55, 0.63, 0.69, and 0.85 dB/cm/MHz, respectively, and ATT increased with an increase in the steatosis grade (P < 0.001). Attenuation coefficient was significantly correlated with fat area (r = 0.50, P < 0.001). The area under the receiver operating characteristic curve corresponding to S ≥ 1, S ≥ 2, and S ≥ 3 were 0.79, 0.87, and 0.96, respectively. Similarly, the sensitivity and specificity of S ≥ 1, S ≥ 2, and S ≥ 3 were 72%, 82%, and 87% and 72%, 82%, and 89%, respectively.
Conclusions
The newly developed ATT measurement for evaluation of liver steatosis was closely correlated with steatosis grade and automated quantification of fat area, and it provides clinically relevant information.
Abstract
It was recently reported that hepatocellular carcinoma (HCC) patients with non-alcoholic steatohepatitis (NASH) are not responsive to immune-checkpoint inhibitor (ICI) treatment. The present ...study aimed to evaluate the therapeutic efficacy of lenvatinib in patients with non-alcoholic fatty liver disease (NAFLD)/NASH-related unresectable-HCC (u-HCC). Five hundred thirty u-HCC patients with Child–Pugh A were enrolled, and divided into the NAFLD/NASH (n = 103) and Viral/Alcohol (n = 427) groups. Clinical features were compared in a retrospective manner. Progression-free survival (PFS) was better in the NAFLD/NASH than the Viral/Alcohol group (median 9.3 vs. 7.5 months, P = 0.012), while there was no significant difference in overall survival (OS) (20.5 vs. 16.9 months, P = 0.057). In Cox-hazard analysis of prognostic factors for PFS, elevated ALT (≥ 30 U/L) (HR 1.247, P = 0.029), modified ALBI grade 2b (HR 1.236, P = 0.047), elevated AFP (≥ 400 ng/mL) (HR 1.294, P = 0.014), and NAFLD/NASH etiology (HR 0.763, P = 0.036) were significant prognostic factors. NAFLD/NASH etiology was not a significant prognostic factor in Cox-hazard analysis for OS (HR0.758, P = 0.092), whereas AFP (≥ 400 ng/mL) (HR 1.402, P = 0.009), BCLC C stage (HR 1.297, P = 0.035), later line use (HR 0.737, P = 0.014), and modified ALBI grade 2b (HR 1.875, P < 0.001) were significant. Lenvatinib can improve the prognosis of patients affected by u-HCC irrespective of HCC etiology or its line of treatment.
We have developed a diagnostic technique to evaluate hepatic steatosis using the attenuation coefficient (ATT) in ultrasound B mode imaging. A controlled attenuation parameter (CAP) by ...vibration-controlled transient elastography (VCTE) has also been used to evaluate hepatic steatosis. As that method uses ultrasound A mode, visualizing the liver in real time is difficult. We designed this clinical study to evaluate the diagnostic advantage of our technique using ATT compared to CAP.
The study group included 94 patients with chronic liver disease who had undergone both ATT and CAP assessment at the time of liver biopsy. The M-probe and XL-probe were used for CAP measurement. Data for ATT and CAP were compared as a function of the steatosis grade.
The area under the receiver operating characteristic curve (AUC-ROCs) for ATT and PAC as a function of the steatosis grade were as follows: grade 1, 0.74 and 0.81; grade 2, 0.80 and 0.85; and grade 3, 0.96 and 0.98, respectively.
The accuracy of steatosis grade diagnosis using ATT was the same as that using CAP, with no significant differences and with the added advantage of B mode ultrasound being more convenient and rapid, compared to A mode ultrasound, particularly for patients with subcutaneous fat thickness ≥2 cm.

In patients with compensated advanced chronic liver disease (cACLD), the invasive measurement of hepatic venous pressure gradient is the best predictor of hepatic decompensation. This study aimed at ...developing an alternative risk prediction model to provide a decompensation risk assessment in cACLD.
Patients with cACLD were retrospectively included from 9 international centers within the Portal Hypertension Alliance in China (CHESS) network. Baseline variables from a Japanese cohort of 197 patients with cACLD were examined and fitted a Cox hazard regression model to develop a specific score for predicting hepatic decompensation. The novel score was validated in an external cohort (n = 770) from 5 centers in China, Singapore, Korea, and Egypt, and was further assessed for the ability of predicting clinically significant portal hypertension in a hepatic venous pressure gradient cohort (n = 285).
In the derivation cohort, independent predictors of hepatic decompensation were identified including Stiffness of liver, Albumin, Varices, and platElets and fitted to develop the novel score, termed "SAVE" score. This score performed significantly better (all P < 0.05) than other assessed methods with a time-dependent receiver operating characteristic curve of 0.89 (95% confidence interval CI: 0.83-0.94) and 0.83 (95% CI: 0.73-0.92) in the derivation and validation cohorts, respectively. The decompensation risk was best stratified by the cutoff values at -6 and -4.5. The 5-year cumulative incidences of decompensation were 0%, 24.9%, and 69.0% in the low-risk, middle-risk, and high-risk groups, respectively ( P < 0.001). The SAVE score also accurately predicted clinically significant portal hypertension (AUC, 0.85 95% CI: 0.80-0.90).
The SAVE score can be readily incorporated into clinical practice to accurately predict the individual risk of hepatic decompensation in cACLD.
For patients with cirrhosis, no definitive predictor of the efficacy and prognosis of tolvaptan treatment exists. We assessed the cisterna chyli's utility as an optimal marker. We retrospectively ...enrolled 172 patients with cirrhosis. The effect of tolvaptan was evaluated using post-treatment survival time. The overall response to tolvaptan was 52.3%. The median cisterna chyli diameter was 4.1 mm. Of 172 patients, 100 were included in the pilot set and 72 in the validation set. According to the Youden index, the cisterna chyli diameter's cutoff value was 4 mm, with a sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio of 92%, 83%, 86%, 91%, 5.43, and 0.09, respectively, in the pilot set. The area under the curve of the cisterna chyli diameter for evaluating tolvaptan's effect was 0.911 and 0.988 in the pilot and validation sets, respectively. During multivariate analysis, cisterna chyli narrowing and furosemide treatment were significant predictive factors for tolvaptan's insufficient effect. Cumulative liver transplantation-free survival rates were significantly higher in patients with cisterna chyli dilatation than in those without (p = 0.028). Our findings suggest a strong association of cisterna chyli with tolvaptan treatment response in patients with cirrhosis and hepatic edema.
Endoplasmic reticulum (ER) stress plays an important role in hepatocyte degeneration, especially in patients with chronic liver injury. Protein kinase R-like endoplasmic reticulum kinase (PERK) is a ...key molecule in ER stress. PERK may contribute to apoptotic cell death in HCC, however the details of the mechanism are not clear. In this study, we identified PERK-associated molecules using transcriptome analysis. We modulated PERK expression using a plasmid, tunicamycin and siRNA against PERK, and then confirmed the target gene expression with real-time PCR and Northern blotting. We further analyzed the apoptotic function. Transcriptome analysis revealed that expression of the RNA component of mitochondrial RNA processing endoribonuclease (RMRP), which is a long noncoding RNA, was strongly correlated with the function of PERK. The expression of RMRP was correlated with the expression of PERK in experiments with the siRNA and PERK plasmid in both HCC cell lines and human HCC tissue. Furthermore, RMRP downregulation induced apoptotic cell death. RMRP is downregulated by PERK, which induces apoptosis in HCC. RMRP could be a new therapeutic target to regulate HCC in patients with chronic liver diseases associated with ER stress.
Background/Aim
Although systemic therapy is recommended for patients with multiple intermediate stage unresectable hepatocellular carcinoma (u‐HCC) classified as beyond the up‐to‐7 criteria (UT‐7 ...out/multiple) as a transcatheter arterial chemoembolization (TACE) unsuitable condition, few reports have examined the therapeutic efficacy of atezolizumab plus bevacizumab combination therapy (Atez/Bev) in such cases. This study aimed to elucidate the therapeutic response of Atez/Bev in u‐HCC patients classified as UT‐7 out/multiple.
Material/Methods
From September 2020 to September 2021, 95 u‐HCC Japanese patients classified as UT‐7 out/multiple/Child‐Pugh A were enrolled from 21 institutions (median age 76 years, males 73, Child‐Pugh 5:6 = 68:27, TNM stage II:III = 17:78). Therapeutic response was retrospectively evaluated using Response Evaluation Criteria in Solid Tumors (RECIST), ver. 1.1 and modified RECIST (mRECIST).
Results
Atez/Bev was given as first‐line treatment to 52 (54.7%). Objective response rate (ORR)/disease control rate (DCR) at six weeks of RECIST and mRECIST were 17.7%/84.7% and 42.5%/86.2%, respectively. Median PFS was 8.0 months (median observation period: 6.0 months). Child‐Pugh A/modified Albumin‐bilirubin grade (mALBI) 1 and 2a at baseline, 3, 6, and 9 weeks, were 100%/69.4%, 89.8%/57.3%, 94.8%/65.3%, and 91.4%/60.0%, respectively. Among adverse events (any‐grade, >10%) during the present observation period, general fatigue was most frequent (23.2%), followed by urine protein (21.1%), appetite loss (20.0%), and hypertension (13.7%).
Conclusion
Atez/Bev treatment showed favorable therapeutic response with less influence on hepatic function, suggesting it as a useful therapeutic option for patients with such condition.
Lenvatinib has anti-tumor activity against advanced hepatocellular carcinoma (HCC). Hypothyroidism is also a frequent complication in patients treated with lenvatinib. However, studies on ...lenvatinib-induced thyroid toxicity and destructive thyroiditis are limited. Therefore, this study aimed to clarify the frequency and timing of thyroid abnormalities in lenvatinib for unresectable HCC. This retrospective study enrolled 50 patients with advanced HCC treated with lenvatinib. Patients were classified to have euthyroid, subclinical hypothyroidism, overt hypothyroidism, and thyrotoxicosis. The timing of thyroid dysfunction was assessed, and risk factors for incident hypothyroidism or thyrotoxicosis were evaluated using multivariate models. Subclinical hypothyroidism, overt hypothyroidism, and thyrotoxicosis occurred in 7 (14.0%), 26 (52.0%), and 5 (10.0%) patients, respectively. In the 33 patients with hypothyroidism, 27 (84.4%) developed the condition within 2 weeks of starting lenvatinib treatment. Of the 5 patients with thyrotoxicosis, 3 developed the condition within 8 weeks of starting lenvatinib administration. One patient developed thyrotoxicosis in only 1 week of the initiation of treatment. No correlation between the presence of antibodies and the incidence and severity of thyroid dysfunction due to the autoimmune mechanism was observed. The progression-free survival was significantly better in the hypothyroidism group. Lenvatinib treatment for unresectable HCC not only causes hypothyroidism, but also thyrotoxicosis. Moreover, these thyroid conditions develop within the early period of treatment at a higher prevalence. Patients with thyroid dysfunction had better prognosis. Based on these results, in patients administered with lenvatinib, there is need for careful assessment for the possibility of thyroid dysfunction from the onset of treatment.
Aim
Regorafenib is a second‐line treatment for unresectable hepatocellular carcinoma after sorafenib‐refractory treatment. This study examined the effects of regorafenib administration on hepatic ...functional reserve and the treatment course after regorafenib discontinuation.
Methods
This retrospective, multicenter study involved 51 patients treated with regorafenib after sorafenib‐refractory treatment for u‐HCC at seven institutions before March 2021.
Results
Fourteen, 13, and 24 patients were classified based on modified albumin–bilirubin (mALBI) grade 1, 2a, and 2b, respectively. The median survival time and progression‐free survival were 16.7 and 3.3 months, respectively. Only mALBI grade 2b or 3 was significantly associated with survival rate (hazard ratio, 2.13; 95% confidence interval, 1.01–4.49; p = 0.047). A comparison of median ALBI scores at the initiation of regorafenib (−2.35) with those at 4 weeks (−1.93) revealed a significant relative change (p = 0.0001). After 4 weeks, grade 1 or 2a persisted in 15 patients (Group 1); grade 1 or 2a deteriorated to 2b in 12 patients (Group 2); grade 2b or 3 before regorafenib administration was present in 22 patients (Group 3); and MST was 33.3, 12.8, and 11.3 months in the three groups, respectively (p = 0.05). Patients treated with lenvatinib (LEN) (n = 27, MST = 23.4 months) after regorafenib had a significantly longer survival time from regorafenib initiation than those not treated with LEN (n = 24, 11.8 months; p = 0.043).
Conclusions
Hepatic functional reserve significantly declined after regorafenib administration. During regorafenib treatment, favorable hepatic functional reserve before administration and maintenance of favorable hepatic reserve after administration lead to prolonged prognosis.
