Su2047 Perihepatic Lymph Node Enlargement is a Negative Predictor of Liver Cancer Development in Chronic Hepatitis C Patients
ABSTRACT BACKGROUND: Perihepatic lymph node enlargement (PLNE) is a common ultrasound finding in chronic hepatitis C patients. Although PLNE is considered to reflect the inflammatory response to hepatitis C virus (HCV), its clinical significance remains unclear. METHODS: Between December 2004 and June 2005, we enrolled 846 chronic hepatitis C patients in whom adequate ultrasound examinations had been performed. PLNE was defined as a perihepatic lymph node that was at least 1 cm in the longest axis by ultrasonography. We analyzed the clinical features of patients with PLNE and prospectively investigated the association between PLNE and hepatocellular carcinoma (HCC) development. RESULTS: We detected PLNE in 169 (20.0 %) patients. Female sex, lower body mass index (BMI), and HCV serotype 1 were independently associated with the presence of PLNE. However, there were no significant differences in liver function tests, liver stiffness, and hepatitis C viral loads between patients with and without PLNE. During the follow-up period (mean 4.8 years), HCC developed in 121 patients. Unexpectedly, patients with PLNE revealed a significantly lower risk of HCC development than those without PLNE (p = 0.019, log rank test). Multivariate analysis revealed that the presence of PLNE was an independent negative predictor of HCC development (hazard ratio 0.551, p = 0.042). In addition, the sustained viral response rate in patients who received interferon (IFN) therapy was significantly lower in patients with PLNE than in patients without PLNE. CONCLUSIONS: Patients with PLNE had a lower risk of HCC development than those without PLNE. This study may provide new insights into daily clinical practice and the pathophysiology of HCV-induced hepatitis and hepatocarcinogenesis.

ABSTRACT: AimAlthough perihepatic lymph node enlargement (PLNE) is reportedly associated with the negative outcome of interferon therapy for chronic hepatitis C, there were limitations in that the results were obtained in patients with various genotypes, viral loads and treatment regimens. We aimed to precisely clarify the significance of PLNE in interferon therapy for chronic hepatitis C. Methods Between December 2004 and June 2005, 112 patients with hepatitis C virus (HCV) genotype 1 and HCV RNA of more than 100KIU/mL were enrolled, who underwent pegylated interferon- plus ribavirin therapy thereafter. PLNE was defined as a perihepatic lymph node of more than 1cm in the longest axis by ultrasonography. ResultsThe sustained virological response (SVR) rate was lower in patients with PLNE (4/22, 18.2%) than in those without (37/90, 41.1%; P=0.045) and viral load decline was smaller in patients with PLNE than in those without (P=0.028). The proportion of PLNE positive patients was the smallest in the SVR group (P=0.033) among the patient groups divided by the treatment outcome. PLNE was retained as a negative predictor for SVR by multivariate logistic regression analysis (P=0.012). Furthermore, PLNE was not significantly associated with the mutations at HCV core protein and at interferon sensitivity-determining region, or interleukin-28B polymorphism in 45 patients with HCV genotype 1, enrolled between December 2011 and March 2012. ConclusionPLNE is a negative predictor for SVR in patients with HCV genotype 1 and HCV RNA of more than 100KIU/mL treated with pegylated interferon- plus ribavirin, independent of other known predictors for SVR.Hepatology Research 01/2013; 43(10).

ABSTRACT: Background & AimsAlthough perihepatic lymph node enlargement (PLNE) is frequently observed in chronic liver disease, little is known about PLNE in chronic hepatitis B virus (HBV) infection. We aimed to evaluate this issue.Methods We originally enrolled consecutive 502 patients with chronic HBV infection. Among them, 288 patients without history of interferon based or nucleoside-analog treatment and hepatocellular carcinoma (HCC) were primarily analyzed.ResultsPLNE was detected in 27 of 288 (9.4%) patients, which was fewer than that in chronic hepatitis C patients but more than that in subjects undertaking a general health examination as previously reported. The presence of PLNE was significantly associated with a higher probability of having an APRI >1.5 (11.1% vs. 1.5%, P = 0.01), a higher AST level (38.0 vs. 26.8 U/L, P = 0.001), a higher ALT level (50.1 vs. 28.0 U/L, P <0.0001), and a lower platelet count (18.6 vs. 20.6 × 104/μL, P = 0.048) after adjustment for sex and age. However, in our original sample (n = 502), PLNE was observed in 1.4% of the patients with HCC and/or its history whereas 9.2% of the patients without HCC, and the proportion was significantly lower in patients with HCC and/or its history (P = 0.03).ConclusionsPLNE was associated with liver fibrosis and hepatocellular injury, but was negatively associated with HCC in chronic HBV infection.Hepatology Research 05/2014; 45(4).
