We report on a case of a 57-year-old male who underwent a curative resection for hepatocellular carcinoma (HCC) with histological confirmation of a spontaneously necrotized tumor. Initial serum AFP level was 4,778 ng/mL. A 3.7 cm hyperechoic mass in segment 6 of the liver was observed on ultrasonography and dynamic contrast-enhanced liver MRI showed a 3.7x3.1 cm sized HCC. He was scheduled to undergo curative surgical resection under the clinical diagnosis of an early stage HCC (Barcelona Clinic Liver Cancer stage A). Without treatment, the serum AFP level declined rapidly to 50 ng/mL over five weeks. He underwent curative wedge resection of segment 6 of the liver. Histology revealed complete necrosis of the mass rimmed by inflamed fibrous capsule on a background of HBV-related cirrhosis with infiltration of lymphoplasma cells. Exact pathophysiology underlying this event is unknown. Among the proposed mechanisms of spontaneous neoplastic remission of HCC, circulatory disturbance and activation of host immune response offer the most scientific explanation for the complete histologic necrosis of HCC in the resected mass seen in our patient.

BACKGROUND/AIMS: Transient elastography (Fibroscan, Echosens, France) is a new, simple, and non-invasive method to assess the degree of hepatic fibrosis by measuring liver stiffness. Recent reports have shown that liver stiffness measurement using Fibroscan allowed accurate prediction of hepatic fibrosis in patient with chronic hepatitis C. The aim of this study was to evaluate accuracy of Fibroscan for the detection of hepatic fibrosis in Korea with various etiologies of chronic liver disease by comparison with fibrosis assessed by histologic examination. METHODS: Fifty-four patients with chronic liver diseases, which were histologically confirmed within recent 6 months were enrolled. Etiologies were HBV, HCV infection, autoimmune hepatitis, and non alcoholic steatohepatitis. Hepatic fibrosis was graded on the basis of standard guideline proposed by the Korean Study Group for the Pathology of Digestive Diseases. RESULTS: Fibroscan values were significantly higher in F3 (16.96 kPa) and F4 (19.86 kPa) than others (p=0.003). Liver stiffness measurement was significantly correlated to the fibrosis stage (r=0.614, p<0.0001). CONCLUSIONS: Liver stiffness measurement by Fibroscan is a promising method for the assessment of hepatic fibrosis in chronic liver disease because it accompanies no complication.

Breast cancer is a rare disease in men. We report a case of 53-year-old obese male, with known cryptogenic cirrhosis and hepatocellular carcinoma, presenting a tender mass on left breast. He was diagnosed with invasive intraductal carcinoma, which was consistent with a sporadic lesion. On the basis of previous literatures, obesity can be regarded as a cause for breast cancer even in men. However, there has been inconsistent data about link between liver cirrhosis and male breast cancer, which can be due to heterogenity in the etiology of cirrhosis. Through this case, it can be postulated that the risk for male breast cancer may vary according to the etiology of cirrhosis.

BACKGROUND/AIMS: The red-blood-cell distribution width (RDW) is a newly recognized risk marker in patients with cardiovascular disease, but its role in nonalcoholic fatty liver disease (NAFLD) has not been well defined. The aim of the present study was to determine the association between RDW values and the level of fibrosis in NAFLD according to BARD and FIB-4 scores. METHODS: This study included 24,547 subjects who had been diagnosed with NAFLD based on abdominal ultrasonography and questionnaires about alcohol consumption. The degree of liver fibrosis was determined according to BARD and FIB-4 scores. The association between RDW values and the degree of fibrosis in NAFLD was analyzed retrospectively. RESULTS: After adjusting for age, hemoglobin level, mean corpuscular volume, history of hypertension, history of diabetes, and high-sensitivity C-reactive protein, the RDW values were 12.61+/-0.41% (mean+/-SD), 12.70+/-0.70%, 12.77+/-0.62%, 12.87+/-0.82%, and 13.25+/-0.90% for those with BARD scores of 0, 1, 2, 3, and 4, respectively, and 12.71+/-0.72%, 12.79+/-0.66%, and 13.23+/-1.52% for those with FIB-4 scores of <1.30, 1.31-2.66, and > or =2.67, respectively (P<0.05). The prevalence of advanced fibrosis (BARD score of 24 and FIB-4 score of > or =1.3) increased with the RDW [BARD score: 51.1% in quartile 1 (Q1) vs. 63.6% in Q4; FIB-4 score: 6.9% in Q1 vs. 10.5% in Q4; P<0.001]. After adjustments, the odds ratio of having advanced fibrosis for those in Q4 compared to Q1 were 1.76 (95%CI=1.55-2.00, P<0.001) relative to BARD score and 1.69 (95%CI=1.52-1.98, P<0.001) relative to FIB-4 score. CONCLUSIONS: Elevated RDW is independently associated with advanced fibrosis in NAFLD.

BACKGROUND/AIMS: The optimal management of patients exhibiting a partial virologic response (PVR) to entecavir (ETV) has not been determined . The aim of this study was to determine the long-term efficacy of prolonged ETV monotherapy in treatment-naive chronic hepatitis B (CHB) patients exhibiting a PVR to ETV therapy. METHODS: This study included 364 treatment-naive CHB patients treated with ETV for > or =48 weeks and who received continuous ETV monotherapy for > or =96 weeks. PVR was defined as a decrease in serum hepatitis B virus (HBV) DNA of more than 2 log10 IU/mL from baseline but with detectable HBV DNA by real-time PCR assay at week 48. RESULTS: Fifty-two of the 364 patients (14.3%) showed a PVR. Among them, 41 patients received continuous ETV monotherapy for > or =96 weeks (median duration 144 weeks, range 96-312 weeks), and 40 of these patients (95%) achieved a virologic response (VR, HBV DNA <20 IU/mL) during prolonged ETV monotherapy (median duration 78 weeks, range 60-288 weeks). The cumulative probabilities of a VR at weeks 96, 144, and 192 from treatment initiation were 78.0%, 92.7%, and 95.1%, respectively. The VR rate was 97.2% (35/36) in HBeAg-positive patients and 100% (5/5) in HBeAg-negative patients. In multivariate analysis, HBeAg positivity (odds ratio [OR], 9.231; 95% confidence interval [CI], 1.03-82.91; P=0.047) and a high baseline HBV DNA level (OR, 0.170; 95% CI, 0.08-0.37; P=0.000) were independently associated with a delayed virologic response. No patient developed genotypic resistance to ETV during follow-up. CONCLUSIONS: Long-term ETV monotherapy is effective for achieving a VR in treatment-naive CHB patients exhibiting a PVR to ETV. HBeAg positivity and high baseline HBV DNA level were independently associated with a delayed virologic response.

BACKGROUND/AIMS: Transient elastography is a new noninvasive tool for measuring liver stiffness that accurately predicts significant fibrosis and cirrhosis. However, several studies have indicated that liver stiffness can be significantly influenced by major changes in aminotransferase in patients with chronic viral hepatitis. The aim of this study was to determine the factors influencing liver stiffness in patients with chronic liver disease. METHODS: We studied 158 patients with chronic liver disease who underwent transient elastography and liver biopsy sampling. Histologic findings on fibrosis and necroinflammatory activity in the biopsy specimens were evaluated according to the Korean Society of Pathologists Scoring System. Routine biochemical tests were performed according to standard methods. RESULTS: Liver stiffness was strongly correlated with liver fibrosis stage (Spearman coefficient=0.636, P<0.001), lobular activity (Spearman coefficient=0.359, P<0.001), and portoperiportal activity grade (Spearman coefficient=0.448, P<0.001). Liver stiffness was significantly associated with serum levels of total bilirubin (P=0.025), direct bilirubin (P=0.049), gamma-glutamyl transpeptidase (P=0.014), platelet count (P=0.004), albumin (P<0.001), and international normalized ratio (P<0.001). Multivariate analysis showed that fibrosis stage (B 3.50, P=0.009) and lobular activity grade (B 3.25, P=0.047) were independently associated with liver stiffness. CONCLUSIONS: Liver stiffness as measured by transient elastography is associated with the grade of necroinflammatory activity and the stage of fibrosis, irrespective of serum ALT levels.
