Background and Aim Based on up-to-seven criteria and Child- Pugh score, four substages of Barcelona Clinic Liver Cancer ( BCLC) intermediate hepatocellular carcinoma ( HCC) were proposed. The purpose of this study was to validate and modify this proposal. Methods Between January 2002 and February 2011, newly diagnosed intermediate HCC patients underwent transarterial embolization ( TAE) were enrolled. Patients were stratified into four ( B1- B4) substages and followed up until death or end of 2012. Patients' survivals and discriminatory ability of substaging systems were compared. Results Five-hundred and eighty patients were enrolled. There were 56.6%, 33.8%, 7.4%, and 2.2% in substage B1, B2, B3, and B4. The 5-year survival rate was 21.4%, 13.9%, 7.4%, and 7.7% with median survival time of 2.4, 1.3, 0.5, and 0.8 years ( P < 0.001). In addition to substage B1- B4, α-fetoprotein ( AFP) level was an independent factor associated with survival in multivariate analysis. According to AFP < or > 200 ng/mL, B1 was classified into B1a and B1b, and B2 into B2a and B2b. There were no differences in survivals between B1b and B2a ( P = 0.174), and B2b and B3 ( P = 0.785). Patients were re-classified into modified (m) B1 ( B1a), mB2 ( B1b + B2a), m B3 ( B2b + B3). The modified substages (m B1-m B3) showed a more desirable substaging system. Conclusions For BCLC intermediate HCC patients, substages B1- B4 were useful in predicting survival after TAE. However, modified substaging system provided better prognostic prediction.

Background and Aims: Hepatitis C virus (HCV) infection is reported to be associated with or to cause type 2 diabetes mellitus (T2DM). Our study aimed to elucidate the role of triglyceride (TG) and cholesterol (CHOL) levels in the association between anti-HCV seropositivity and T2DM in an HCV-endemic area. Methods: We analyzed a computerized dataset of 56 338 residents from a community-based comprehensive screening program in Tainan County in southern Taiwan. Fasting glucose, anti-HCV status, hepatitis B surface antigen (HBsAg) status, platelet counts, TG levels, CHOL levels, age, gender, and body mass index were included in the analyses. Multivariate logistic analysis was used to identify factors independently associated with T2DM. Results: Older age, being overweight, thrombocytopenia, hypertriglyceridemia, hypercholesterolemia, anti-HCV seropositivity, and HBsAg seronegativity were common factors independently associated with diabetes. Among all models of multiple logistic regression analysis used for identifying factors independently associated with T2DM, anti-HCV seropositivity was only identified in the models that included either hypertriglyceridemia or hypercholesterolemia. When subjects were divided into hyperlipidemia (CHOL, > 200 or TG, > 150 mg/dL; n = 33 393) or non-hyperlipidemia subgroups (CHOL, < 200 and TG, < 150 mg/dL; n = 22 945), anti-HCV seropositivity was identified as an independent factor only in the non-hyperlipidemia subgroup. The odds ratio was 1.35, with a 95% confidence interval of 1.17-1.55. Conclusions: This study demonstrates that the lipid level is associated with the relationship between T2DM and anti-HCV seropositivity in non-hyperlipidemic individuals. However, the relationship between HCV and T2DM did not exist when the lipid level was not included in the analysis. [ABSTRACT FROM AUTHOR]

Background and Aim: Long-term trends of anti-hepatitis C virus (HCV) antibody titer and their associated factors in patients with sustained virological response (SVR) were investigated. Methods: From May 1999 to July 2005, a total of 166 SVR consecutive patients (M/F: 86/80) were enrolled. Anti-HCV titer, samples to cut-off (S/CO) ratios, were measured with AxSYM HCV version 3.0. Their S/CO ratios were followed every 6 months after SVR and the patterns over time were identified by trajectory analyses. Changes of recombinant immunoblot assay (RIBA) pattern before treatment and end of follow-up were compared ( n = 64). Results: The mean duration of follow-up was 4.7 ± 1.5 years (median 4.3; range 3-9 years). The rates of S/CO ratios decreased annually ( P < 0.001). Two of them (1.2%) achieved seroreversion. Trajectory groups included lower pretreatment S/CO ratios (LAB, n = 83), rapid decrease (RD, n = 62) and slow decrease (SD, n = 21) groups. Comparing LAB to RD group, odds ratio (OR) of increased platelet count per 1 unit and interferon regimen was 1.12 (95% confidence interval [CI] 1.04-1.20) and 2.17 (95% CI 1.04-4.52) respectively. Comparing SD to LAB and RD groups, the OR of advanced fibrotic stage, using mild fibrotic stage as a reference, was 4.33 (95% CI 1.49-12.63). Reaction strength of all four RIBA bands decreased significantly at the end of follow-up. Conclusions: Anti-HCV titers decreased annually during long-term follow-up after SVR. Higher pretreatment platelet count, interferon regimen and mild fibrosis were associated with decreased anti-HCV titers. However, only a few cases achieved seroreversion. All RIBA bands decreased significantly after long-term follow-up. [ABSTRACT FROM AUTHOR]
