RESUMO
A 19-year-old Japanese man was referred for a further evaluation of liver dysfunction. Despite the absence of symptoms or obesity, the liver biopsy results were consistent with non-alcoholic steatohepatitis. Subsequent investigations revealed low serum ceruloplasmin, increased urinary copper excretion, and a known mutation c.3809A>G (p.Asn1270Ser) in the copper-transporting enzyme P-type ATPase (ATP7B) gene, leading to a diagnosis of Wilson's disease. A previously unreported variant, i.e., c.3866A>T (p.Asp1289Val) was detected on the patient's other allele and was considered a novel mutation, classified as 'likely pathogenic' according to the American College of Medical Genetics guidelines.
RESUMO
Introduction: Immune checkpoint inhibitors are sometimes associated with immune-related adverse events during or after treatment. Among these, aseptic meningitis is a rare and serious complication. We report the first case of atezolizumab-induced aseptic meningitis, which occurred during treatment for advanced hepatocellular carcinoma (HCC). Case Presentation: A 74-year-old woman diagnosed with advanced HCC and treated with first-line atezolizumab plus bevacizumab developed anorexia, fatigue, and fever, after three treatment cycles. Cerebrospinal fluid examination showed slightly increased cell count and protein level but no infection or malignancy. Contrast enhancement along the cerebral sulcus was evident in contrast-enhanced magnetic resonance imaging, and the patient was diagnosed with aseptic meningitis associated with atezolizumab. Steroid therapy soon improved her clinical symptoms, and the contrast enhancement along the cerebral sulcus disappeared. Conclusion: Clinicians should monitor to avoid serious immune-related adverse events, such as aseptic meningitis, in patients during treatment of HCC with immune checkpoint inhibitors and make the diagnosis as soon as possible.
RESUMO
AIM: Sequential therapies are essential to extend overall survival (OS) in patients with unresectable hepatocellular carcinoma (HCC). Several second-line treatments with molecular target agents have shown survival benefits. However, the significance of post-progression survival (PPS) in extending OS in patients with HCC given such treatments remains uncertain. METHODS: Through a systematic review of the literature in the PubMed database, this study investigated the correlation between PPS and OS and that between progression-free survival (PFS) and OS in patients with HCC given second-line treatments. RESULTS: In total, 3935 patients who had received second-line treatment with regorafenib, ramucirumab, or cabozantinib, which are approved molecular target agents, were identified. In the patients treated with regorafenib, PPS showed a strong correlation with OS (R2 = 0.729, R = 0.854, p < 0.001) whereas PFS showed a weak correlation (R2 = 0.218, R = 0.467, p = 0.021). In the patients treated with ramucirumab, PPS showed a strong correlation with OS (R2 = 0.800, R = 0.894, p = 0.016) whereas PFS showed a negligible correlation (R2 = 0.020, R = 0.140, p = 0.791). In the patients treated with cabozantinib, PPS showed a strong correlation with OS (R2 = 0.856, R = 0.925, p = 0.003) as did PFS (R2 = 0.946, R = 0.973, p < 0.001). CONCLUSIONS: PPS plays a more significant role than PFS in extending OS in patients given second-line treatment for unresectable HCC. Sequential therapies after disease progression in second-line treatment are essential to acquire good OS. Maintenance of hepatic reserve function and the patient's general condition is essential during systemic treatments for unresectable HCC.
RESUMO
INTRODUCTION: Atezolizumab plus bevacizumab (Atez/Bev) is a standard treatment for unresectable hepatocellular carcinoma (HCC) due to its good antitumor and survival prolongation effects. Post-progression survival (PPS) has been reported to be a great contributor in the treatment with tyrosine kinase inhibitors for unresectable HCC. This study aimed to clarify the significance of progression-free survival (PFS) or PPS of Atez/Bev treatment for HCC. METHODS: We analyzed the correlations of PFS and PPS with overall survival (OS) in studies of HCC patients treated with Atez/Bev and evaluated the contribution to OS in Atez/Bev treatment with patients at our institutions as clinical practice. RESULTS: Analysis of 18 studies involving 3,752 patients treated with Atez/Bev found that PPS had a stronger correlation with OS (R2 = 0.872, p < 0.001) than did PFS (R2 = 0.605, p = 0.001). Analysis of 80 patients with unresectable HCC treated with Atez/Bev found that presence of antitumor responses during Atez/Bev was the most significant contributor to OS, and post-progression treatment after Atez/Bev also significantly contribute to OS. CONCLUSION: The presence of antitumor response with tumor shrinkage during Atez/Bev treatment contributes to good OS through its durable response. Atez/Bev treatment could be considered as first-line treatment for unresectable HCC. However, there is a need for optimal biomarkers for good antitumor response.

An 80-year-old Japanese man presented to our hospital with intra-abdominal hemorrhage due to a ruptured liver tumor. Transcatheter arterial embolization (TAE) temporarily achieved hemostasis, but he died following re-rupture 4 days later. Based on autopsy findings, the liver tumor was diagnosed as hepatic angiosarcoma. Embolic agents used during embolization were identified within the hepatic small interlobular arteries. However, there were no findings of tumor cell necrosis or ischemic change in the angiosarcoma. In the present case, TAE alone did not induce ischemia-induced tumor necrosis, suggesting that TAE might be unsuitable to treat hepatic angiosarcoma. Treatment optimization for ruptured hepatic angiosarcoma is desired.
RESUMO
BACKGROUND: Thrombocytopenia due to hypersplenism is a major complication of hepatitis C virus (HCV)-associated cirrhosis. HCV eradication improves these complications in some patients, but the long-term effects of HCV eradication on these complications remain unclear, especially in patients treated with direct acting antivirals (DAAs). The aim was to evaluate long term changes in thrombocytopenia and leucopenia after HCV eradication with DAAs. METHODS: The present multicenter study retrospectively evaluated changes over 5 years in thrombocytopenia and leukocytopenia, as well as changes in liver fibrosis markers and spleen size, in 115 patients with HCV-cirrhosis treated with DAAs. RESULTS: Thrombocytopenia and leukocytopenia were improved 4 weeks after DAA administration, with thrombocytopenia show further gradual improvement over the next year. Fib-4 index was markedly reduced 1 year after DAA, followed by subsequent gradual reduction over the next 4 years. Spleen size showed gradual annual reductions, with patients experiencing spleen size reduction characterized at baseline by bilirubinemia. CONCLUSIONS: Rapid DAA-associated HCV eradication might lead to rapid disappearance of liver inflammation and bone marrow suppression due to HCV infection. HCV eradication may gradually improve portal hypertension, reducing spleen size.

Sarcomatoid hepatocellular carcinoma (sHCC) is a rare phenotype of HCC with extremely poor prognosis and no established pharmacological treatment. Interventional therapies such as radiofrequency ablation (RFA) or transcatheter arterial embolization (TAE) have been shown to limit the development of sHCC through mechanisms involving hypoxia-induced epithelial-mesenchymal transition. This report describes an 83-year-old man who developed sHCC 2 years after RFA treatment for HCC and experienced sHCC rupture. Following TAE-induced hematostasis, he was administered lenvatinib for tumor control. Although his physical status had improved, due to loss of fever and attenuation of arterial enhancement in the tumor, for 1 month after lenvatinib administration, tumor re-growth was observed 2 months after lenvatinib treatment. His general condition was preserved, and he was treated with 10 courses of atezolizumab plus bevacizumab (Atez+Bev), resulting in tumor shrinkage that was maintained for 3-8 months after Atez+Bev. Findings in this patient showed that combined immunotherapy was effective for sHCC. Further investigation in additional patients is required to maximize prognosis in patients with sHCC.

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.

BACKGROUND/AIM: Lenvatinib is a tyrosine kinase inhibitor (TKI) more effective against hepatocellular carcinoma (HCC) than sorafenib, making lenvatinib a first-line treatment option for patients with unresectable HCC. In patients treated with sorafenib, post-progression survival (PPS) rather than progression-free survival (PFS) is essential for overall survival (OS). However, the importance of PPS for OS in patients treated with lenvatinib is uncertain, and optimal treatment after lenvatinib failure has not yet been established. PATIENTS AND METHODS: The present study investigated the correlations of PFS and PPS with OS in studies of HCC patients treated with lenvatinib by weighted linear regression analysis. Furthermore, the contribution of treatment regimens after lenvatinib failure to OS were evaluated in daily clinical practice. RESULTS: An analysis of 20 studies with 4,054 patients found that PPS had a stronger correlation with OS (r=0.869, p<0.001) than did PFS (r=0.505, p=0.007). Analysis of 79 patients with unresectable HCC treated with first-line lenvatinib showed that subsequent treatment was the most significant contributor to OS. Second-line sorafenib was administered to 25 patients, with late transition to third-line treatment being highest among patients who received second-line treatment. CONCLUSION: PPS contributes significantly to OS in HCC treatment with TKIs, with multi-sequential treatment being a key determinant of longer OS.

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.

The aim of this study was to determine the impact at 5 years of sodium-glucose cotransporter 2 inhibitor (SGLT2i) in nonalcoholic fatty liver disease (NAFLD) with type 2 diabetes mellitus (T2DM) on liver histopathology and clinical features. In this retrospective study, the histological impacts at 5 years after the start of SGLT2i in NAFLD with T2DM were investigated. Six patients with NAFLD and T2DM were treated for the long term with canagliflozin of SGLT2i, and liver biopsies were obtained at the points of the pretreatment, 24 weeks, 3 years, and 5 years after the start of treatment. The primary outcome was liver histopathological changes at 5 years (defined as decrease in NAFLD activity score of one point or more without worsening in fibrosis stage, compared with the pretreatment). The additional treatment of glucagon-like peptide 1 receptor agonist (GLP-1RA) was performed in 2 patients after the point of 3 years, and evaluated as histological worsening. As the primary outcome, histological improvement, no change, and worsening were 50%, 17%, and 33% at 5 years, respectively. Overall, the scores of steatosis, lobular inflammation, ballooning, and fibrosis stage decreased at 5 years in 67%, 33%, 0%, and 33%, respectively. As the secondary outcomes, homeostasis model assessment of insulin resistance and serum ferritin decreased significantly at 5 years. None developed 3-point major adverse cardiovascular events. Two patients with the addition of GLP-1RA on SGLT2i did not show the worsening of steatosis, ballooning, and fibrosis stage at 5 years compared with 3 years. Conclusion: A 5-year follow-up study with SGLT2i indicated the favorable histological impact on NAFLD with T2DM.

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.

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.

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.

INTRODUCTION: It is unclear whether the relationships between changes in fibrosis and circulating microRNA-122 (miR-122) dynamics might influence the prognosis of nonalcoholic fatty liver disease (NAFLD). METHODS: This study investigates the impact of serum miR-122 dynamics and histological changes on the incidence of liver cancer and mortality in 81 Japanese NAFLD patients who underwent serial liver biopsies. The median interval between the first and second liver biopsies was 2.9 years. RESULTS: The fibrosis stage scores indicated progression, no change, and improvement (a decrease of one point or more) in 21.0%, 56.8%, and 22.2% of the patients, respectively. There were 64 patients in the high-risk group who had no improvement in stage scores. Among these, the miR-122 levels were significantly lower in 7 patients with liver cancer than those of the 54 patients who had no liver cancer at the second liver biopsy. The cumulative rates of liver cancer were significantly higher in cases with miR-122 ratios <0.5 (serum miR-122 level at second biopsy to that at first biopsy) than those with ratios ≥0.5. The cumulative survival rates in cases with miR-122 ratios <0.5 tended to be lower than those with ratios ≥0.5. Of the 64 high-risk patients, 39 indicated stage 2 or greater (severe fibrosis stage) at the first liver biopsy and also showed similar results of cumulative liver cancer and survival rates. CONCLUSIONS: Longitudinal examination of serial liver biopsies indicated that the circulating miR-122 dynamics might be useful in predicting the prognosis for NAFLD patients with severe fibrosis stage and no improvement of the stage scores.

Objective The relationship between the prognosis and magnitude of a decrease in tumor blood flow according to estimated tumor differentiation remains unclear. This study investigated the relationship between reductions in the rate of mean computed tomography (CT) attenuation values and the clinical prognosis. Methods We evaluated 63 consecutive patients who received lenvatinib treatment for unresectable hepatocellular carcinoma (HCC). The oncological aggressiveness of the tumors was estimated using classification by dynamic CT enhancement patterns. The utility of changes in mean CT attenuation values of intra-hepatic targets during treatment to estimate the prognosis was investigated by calculating the progression-free survival (PFS) and post-progression survival (PPS). A multivariate analysis was used to identify potential confounders for the survival after progression during lenvatinib therapy. Results The rate of decrease in the mean CT attenuation value gradually increased according to the degree of deterioration in estimated tumor differentiation, and the rate of a decrease in attenuation ≥40% showed a tendency to increase (p=0.064). This trend was reflected by a better objective response in oncological aggressiveness heterogeneous enhancement patterns (Type-3 and Type-4) than a homogeneous enhancement pattern (Type-2) (83% vs. 56% of modified Response Evaluation Criteria in Solid Tumors). This resulted in a similar PFS between the groups (p=0.773), whereas the PPS was significantly worse when the rate of decrease in the attenuation value was ≥40% (p=0.012). A multivariate analysis confirmed that a rate of decease in attenuation value ≥40% was a poor prognostic factor for the PPS (hazard ratio, 2.993; 95% confidence interval, 1.196-7.490; p=0.019). Conclusion A rate of decrease in attenuation ≥40% may reflect a good response of a highly malignant tumor to lenvatinib. Therefore, this value may have utility as a surrogate marker for estimating the oncological aggressiveness of tumors and their associated prognosis.

BACKGROUND AND AIM: 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 overall prognosis in patients with hepatocellular carcinoma treated with lenvatinib. METHODS: Forty-eight consecutive patients who received lenvatinib treatment were reviewed. The oncological aggressiveness of tumors estimated using 18F-FDG-PET/CT was investigated by the analysis of progression-free survival (PFS), post-progression survival (PPS), and overall survival (OS). Multivariate analysis was used to identify potential confounders for OS during lenvatinib therapy. RESULTS: Using the Modified Response Evaluation Criteria in Solid Tumors, a tumor-to-normal liver ratio (TLR) ≥2, indicating higher oncological aggressiveness in HCCs, was associated with a better objective response to lenvatinib than a TLR <2 (78 vs. 62%), resulting in a similar PFS (p = 0.751). Because of a significantly worse PPS, OS with a TLR ≥2 was poor compared to a TLR < 2 (p = 0.012). Multivariate analysis confirmed that a TLR ≥ 2 was associated with poor OS (hazard ratio, 2.709; 95% CI, 1.140-6.436; p = 0.024). Analysis of 24 patients who received a repeat 18F-FDG-PET/CT showed that daily changes expressed as ΔTLR × 103/day over the treatment course tended to be different among the types of subsequent treatment. A R0 resection and lenvatinib-TACE sequential therapy provided good disease control (median, -4.593 and -0.024, respectively) compared with other treatments (median, 5.278) (p = 0.075). CONCLUSION: Lenvatinib has acceptable disease control regardless of estimated tumor differentiation. A high TLR (≥2) is a poor prognostic factor of OS following lenvatinib treatment, while ΔTLR × 103/day provides useful information of disease control status.

We report a rare case of amebiasis associated with an intraabdominal abscess without colitis, an intestinal perforation, or other extraintestinal amebiasis. A patient was admitted with cirrhosis and a history of spontaneous bacterial peritonitis (SBP) and was found to have a high C-reactive protein (CRP) level. Dynamic CT and ultrasound echo findings showed an intraabdominal abscess. No intestinal lesions or extraintestinal lesions other than the intraabdominal abscess were observed. Blood cultures and puncture fluid cultures were negative for bacteria. However, microscopic examination of the puncture fluid showed a cystic form of amoeba, leading to a diagnosis of an amoeba abscess. The abscess disappeared after 10 days of oral treatment with metronidazole. When an abdominal abscess is seen in an immunocompromised patient such as a cirrhotic patient, amoeba infection should be considered as a possible diagnosis.

AIM: The number of patients with fatty liver disease (FLD) is increasing globally. Ethanol consumption in FLD is known to be associated with an increased risk of hepatocellular carcinoma (HCC), but the effects of alcohol consumption on the occurrence of multiple HCCs remain unclear. We explored the relationship between the daily ethanol intake and the HCC number. METHODS: This single-center retrospective study enrolled 114 patients without viral or immune hepatitis undergoing first-line HCC treatment who had been diagnosed with FLD by abdominal ultrasonography or a liver biopsy at the same time as or before HCC detection. We categorized patients into four groups according to the daily alcohol consumption (<20 g: non-alcoholic fatty liver disease, n = 45; 20-39 g: low-intermediate ethanol intake with FLD, n = 13; 40-69 g: high-intermediate ethanol intake with FLD, n = 31; ≥70 g: alcoholic fatty liver disease, n = 25). The relationship between the daily ethanol consumption and the number of HCCs (single or multiple) was examined. RESULTS: The risk of multiple HCCs was significantly higher in the high-intermediate ethanol intake with FLD (HR 2.89, 95% CI 1.04-8.02, P = 0.042) and alcoholic fatty liver disease (HR 3.14, 95% CI 1.07-9.22, P = 0.037) groups than in the others. A multivariate analysis showed that a daily ethanol intake ≥40 g was associated with a significantly increased risk of multiple HCCs (HR 2.82, 95% CI 1.16-6.88, P = 0.023). CONCLUSIONS: Our findings suggest that a high daily ethanol intake might lead to multiple hepatocarcinogenesis in patients with FLD.
