Abstract Background Fib4 index (Fib4) is clinically used as a noninvasive marker of liver fibrosis. In this study, we aimed to preliminarily investigate whether Fib4 can be used to detect individuals who need assessment for alcoholic liver disease (ALD) in the general population by clarifying the detailed association of Fib4 with alcohol consumption and gamma-glutamyl transferase (GGT) among male workers. Methods We analyzed data sets on the comprehensive medical examinations of male workers as cross-sectional and retrospectively longitudinal studies. We enrolled 10 782 males (mean age: 52.2 ± 10.2 years) in FY2019 and 7845 males (mean follow-up: 12.6 ± 6.7 years) who could be consecutively followed up for 20 years from FY2000 to FY2019. Data were evaluated using logistic regression and COX proportional analysis. Results In the cross-sectional setting, the rate of Fib4 ≥ 2.67 in heavy drinkers (≥ 40 g of ethanol/day) was increased dose dependently in those over 65 years old, and that of body mass index ≥ 30 kg/m2 was increased in those over 60 years old, but not in those with fatty liver. The odds ratio (OR) (95% confidence interval [CI]) for heavy drinking was 4.30 (95% CI = 1.90–9.72), and GGT ≥ 200 IU/L was considerably high (OR = 29.05 [95% CI = 17.03–49.56]). In the longitudinal setting, heavy drinkers and those with GGT ≥ 200 IU/L at 10 years after the baseline showed an increased risk for Fib4 ≥ 2.67 (hazard ratio = 2.17 [95% CI = 1.58–2.98] and 7.65 [95% CI 5.26–11.12], respectively). Conclusions The development of Fib4 ≥ 2.67 after 10 years was associated with heavy alcohol drinking and GGT level ≥ 200 IU/L. Therefore, Fib4 combined with GGT could indicate high risk of ALD. However, clinical examinations and course observations are essentially needed.

BackgroundIn Japan, health checkups for workers are legally compulsory. Considering legal health checkup items are important for Japanese workers' health problems. To date, the legal health checkup items for blood cell counts include only red blood cell counts and hemoglobin but not platelet counts. This study aimed to investigate the significance of measuring platelets in workers by showing the association between the FIB-4 index (FIB-4), which can be easily calculated from factors including platelet counts and viral hepatitis infection.MethodBoth cross-sectional and longitudinal analyses were conducted on the comprehensive medical examinations of male workers. In fiscal year (FY) 2019, a logistic regression model was applied to 12,918 examinees. For 13,459 examinees (mean age = 47.5 ± 9.3 SD), FY2000 was set to be followed until FY2019. A total of 149,956 records between FY2000 and FY2019 were analyzed cross-sectionally, and 8,038 men who were consecutively examined to FY2019 at the longest were analyzed longitudinally. Receiver operating characteristic (ROC) curve–area under the ROC curve (ROC–AUC) and Cox proportional methods were used to examine the association between platelet-related indices and viral hepatitis infection.ResultsLogistic regression showed that the risk of FIB-4 ≥ 2.67 was mostly associated with hepatitis C virus antibody (HCVAb) positivity [odds ratio (OR) = 2.51, 95% confidence interval (CI) = 1.08–5.86], while negatively associated with body mass index (BMI) (OR = 0.54, 95% CI = 0.30–0.97), and not associated with the presence of fatty liver. To detect HVC Ab positivity, ROC–AUC showed more effectiveness in FIB-4 than in the AST/ALT ratio (0.776, 95% CI = 0.747–0.773 vs. 0.552; 95% CI = 0.543–0.561). The Cox analysis showed that the risk of FIB-4 ≥ 2.67 was closely associated with hepatitis B virus surface antigen (HBsAg) [hazard ratio (HR) = 3.1, 95% CI = 2.0–4.6] and HCV Ab positivity (HR = 3.2, 95% CI = 2.0–5.0).ConclusionOur results suggest that it might be worth considering that usage of information on platelets in legal health checkups could be some help not to overlook workers with hepatitis virus carriers as a complementary countermeasure, although further investigations are needed into its practical application.

Background: The aims of this study were to evaluate the efficacy of additional treatment, especially lenvatinib-transarterial chemoembolization (TACE) sequential therapy, for unresectable hepatocellular carcinoma (HCC). Methods: Consecutive 56 patients who underwent lenvatinib treatment were reviewed. Oncological aggressiveness of tumor was estimated using a dynamic CT enhancement pattern classification, and clinical impact of subsequent treatment was investigated through analysis of progression-free survival (PFS), post-progression survival (PPS), and multivariate analysis of potential confounders for survival after progression during lenvatinib therapy. Results: Heterogeneous enhancement patterns (Type-3 and -4), which are reportedly associated with higher oncological aggressiveness of HCC, were associated with better objective response to lenvatinib compared to homogeneous enhancement pattern (Type-2) (86 and 85% vs. 53% in modified Response Evaluation Criteria in Solid Tumors), resulting in similar PFS (p = 0.313). Because of significantly worse PPS, overall survival of Type-4 tumor was poor compared to Type-2 or -3 tumors (p = 0.009). However, subgroup of patients who achieved subsequent treatment showed significantly better PPS, regardless of CT enhancement pattern. Multivariate analysis confirmed that use of lenvatinib-TACE sequential treatment after progression during lenvatinib therapy was associated with better PPS (hazard ratio [HR], 0.08; 95% CI, 0.01–0.71; p = 0.023), while Type-4 enhancement pattern was correlated with worse PPS (HR, 2.92; 95% CI, 1.06–8.05; p = 0.039). Conclusion: Oncological aggressiveness of HCC estimated by CT enhancement pattern was predictive of PPS after progression during lenvatinib. Successful subsequent treatment with lenvatinib-TACE sequential therapy may offer survival benefit regardless of CT enhancement pattern of HCC.

Objective: The aim of this study was to evaluate the performance of pretreatment computed tomography (CT) enhancement of hepatocellular carcinoma (HCC) as a potential predictor of response to lenvatinib and its relevance to survival outcomes. Methods: We evaluated 51 consecutive patients who received lenvatinib treatment for unresectable HCC. On imaging analysis, pretreatment arterial/portal phase dynamic CT images were classified as follows: type 2, homogeneous enhancement pattern with increased arterial blood flow; type 3, heterogeneous enhancement pattern with a septum-like structure; and type 4, heterogeneous enhancement pattern with irregularly shaped ring structures. Treatment response was evaluated using modified Response Evaluation Criteria in Solid Tumors at 2-12 weeks after initiation of lenvatinib, and the correlations between the CT enhancement patterns and response to lenvatinib or survival outcomes were investigated. Results: Of the 51 patients, 38 (75%) experienced an objective response (OR). ORs were significantly more common in heterogeneously enhanced HCC (types 3 and 4) than in homogeneous HCC (type 2) (83 vs. 53%, respectively; p = 0.037). Multivariate analysis revealed that pretreatment heterogeneous enhancement pattern is an independent predictor for response to lenvatinib (odds ratio, 4.75; p = 0.042). Presence of OR was associated with longer progression-free survival (PFS) (hazard ratio, 0.36; p = 0.017), and patients with oncologically aggressive type 3 and 4 tumors showed similar PFS to those harboring type 2 tumors (p = 0.455), reflecting that OR was more common in type 3 or 4 tumors compared with type 2 tumors. Although postprogression survival was extremely poor in patients with type 4 tumors (p = 0.064), overall survival after introduction of lenvatinib was not statistically different among the three groups of patients (p = 0.053). Conclusion: The CT enhancement pattern of HCC may predict response to lenvatinib. OR seems to occur more frequently in HCC with oncologically aggressive features and may contribute to prolonged survival through a prolonged progression-free interval, even in an oncologically poor-risk group of patients.
