OBJECTIVETo analyze the clinicopathologic characteristics of well-differentiated hepatocellular carcinoma (WD-HCC), and to find clues for its pathologic diagnosis and differential diagnosis.

METHODSSeventy-three cases of WD-HCC were studied with clinical data analysis, gross and microscopic examination.

RESULTSAmong the 73 cases, the prevalence of HBV (+) and/or HCV (+) was 94.5% (69/73), liver cirrhosis was 80.8% (59/73), increased hepatic cell density was 95.9% (70/73), dilated and irregular hepatic sinus was 89.0% (65/73), prominent trabecularism was 89.0% (65/73), increased cytoplasmic eosinophilia or basophilia was 90.4% (66/73), glandular-like structure was 16.4% (12/73, and fatty degeneration was 42.4% (31/73) .

CONCLUSIONSThere are important clinicopathologic features associated with WD-HCC. These features are useful in the differential diagnosis of WD-HCC with dysplastic nodule (DN), focal nodular hyperplasia (FNH) and hepatocellular adenoma.

OBJECTIVE: To explore the diagnostic value of the serum metabolites identified by high-performance liquid chromatography-mass spectrometry (HPLC/MS) for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). METHODS: A total of 126 patients admitted to Tianjin Third Central Hospital were enrolled, including 27 patients with HBV-related hepatitis with negative viral DNA (DNA-N), 24 with HBV-related hepatitis with positive viral DNA, 24 with HBV-related liver cirrhosis, 27 with HBV-related HCC undergoing surgeries or radiofrequency ablation, and 24 with HBV-related HCC receiving interventional therapy, with 25 healthy volunteers as the normal control group. Serum samples were collected from all the subjects for HPLC/MS analysis, and the data were pretreated to establish an orthogonal partial least- squares discriminant analysis (OPLS-DA) model. The differential serum metabolites were preliminarily screened by comparisons between the HBV groups and the control group, and the characteristic metabolites were identified according to the results of non-parametric test. The potential clinical values of these characteristic metabolites were evaluated using receiver operator characteristic curve (ROC) analysis. RESULTS: A total of 25 characteristic metabolites were identified in the HBV- infected patients, including 9 lysophosphatidylcholines, 2 fatty acids, 17α-estradiol, sphinganine, 5-methylcytidine, vitamin K2, lysophosphatidic acid, glycocholic acid and 8 metabolites with few reports. The patients with HBV- related HCC showed 22 differential serum metabolites compared with the control group, 4 differential metabolites compared with patients with HBV-related liver cirrhosis; 10 differential metabolites were identified in patients with HBV-related HCC receiving interventional therapy compared with those receiving surgical resection or radiofrequency ablation. From the normal control group to HBV-related HCC treated by interventional therapy, many metabolites underwent variations following a similar pattern. CONCLUSIONS We identified 25 characteristic metabolites in patients with HBV-related HCC, and these metabolites may have potential clinical values in the diagnosis of HBV-related HCC. The continuous change of some of these metabolites may indicate the possibility of tumorigenesis, and some may also have indications for the choice of surgical approach.

OBJECTIVEBy means of observing the clinical development of asymptomatic chronic HBsAg carriers (AsC) to explore the clinical rule of development of chronic hepatitis B (CHB) to liver cirrhosis (LC) to hepatocellular carcinoma (HCC) and to seek effective method for blocking the procedure.

METHODSAsCs were selected from health examination according to the diagnostic standard from the National Program for Prevention and Treatment of Viral Hepatitis, by periodical or non-periodical conventional examination of liver diseases, mixed infection of HCV was excluded. A 16-year systematic observation on clinical process of HBV infection series was completed.

RESULTSIn the 217 AsCs observed, 21 cases (9.68%) with the HBsAg negatively converted, the average year negative conversion rate being 0.58%, among them, 13/21 cases (61.9%) had production of anti-HBs antigen; 20 cases were clinically cured; 1 case transferred to HCC; 124 cases (57.14%) remained asymptomatic carriers; 73 transferred to chronic liver disease, showing a tendency of gradually developing from CHB to LC to HCC, the year transferring rate from AsC to LC and HCC being 1.04% and 0.40%, respectively. Fifteen patients died of liver diseases, in which one died of severe CHB, 3 of LC and 11 of HCC.

CONCLUSIONDifferent clinical end-results may reveal in AsCs according to their age and regulation on immune response to HBV. Few of the HCC and LC patients were HBeAg (e+) positive, they often reveal HBeAg (e-) negative or anti-HBe positive. HCC always develops on the basis of liver fibrosis or cirrhosis, which are the prophase of HCC, and patients with liver fibrosis or cirrhosis are the high risk group of developing HCC. HCC is not only the terminal pathologic stage of hepatopathy, but also one of the most important factors that causes death of chronic hepatopathy. From the viewpoint of integrative medicine in typing hepatopathy to observe the clinical speciality of AsC developing to CHB, LC and HCC, it is considered that the degree of blood stasis is in accordance with the development of hepatopathy.

To explore the clinical and pathological characteristics of hepatosplenic gammadelta T-cell lymphoma and its relationship with Epstein-Barr virus infection, the clinical features of a 9-year-old girl with hepatosplenic gammadelta T-cell lymphoma were investigated, the smears of bone marrow was stained with Wright' s stain, biopsies of bone marrow and liver specimen were embedded in plastic and sliced about 4 microm in thickness and routinely stained with HE staining, the immunohistochemical staining was used to mark the tumor cells, and EBER probes were used to detect Epstein-Barr virus RNA. The results showed that the girl presented with prolonged fever, anemia, thrombocytopenia, hepatosplenomegaly, chronic active Epstein-Barr virus infection, and elevated levels of serum ferritin and lactate dehydrogenase. Bone marrow aspirate revealed the infiltration of atypical lymphocytes in the bone marrow stroma. The liver biopsy specimen revealed the infiltration of lymphocytes in the sinusoids, which was positive for the T-cell associated marker CD3 and activated cytotoxicity-associated marker granzyme B. In-situ hybridization analysis with EBER probes revealed that the above-mentioned characteristics were negative in neoplastic cells. It is concluded that hepatosplenic gammadelta T-cell lymphoma is a disease with distinctive clinical, histopathologic, and phenotypic characteristics. Hepatic and/or splenic and/or bone marrow biopsy with combined phenotype is beneficial to diagnosis. Epstein-Barr virus infection is late event involving an already transformed gammadelta T-cell clone.

BACKGROUNDEvaluating a change in the screening rate for hepatocellular carcinoma (HCC) is critical for understanding screening implementation, and whether targeted population groups are receiving proper screening. This study examined recent nationwide changes in HCC screening use among hepatitis B virus (HBV)-infected populations after the introduction of the Korean National Cancer Screening Program and predictors of screening adherence.

METHODSWe analyzed 165 and 276 participants ≥40 years of age who were hepatitis B surface antigen-positive from 2001 (14,936 participants) to 2010-2011 (9159 participants) Korea National Health and Nutrition Examination Surveys, respectively. Demographic data, socioeconomic factors, and HCC screening use were collected by means of self-reported questionnaires.

RESULTSThe rate of HCC screening within the previous 2 years increased significantly from 17.5% in 2001 to 40.3% in 2010-2011 (P < 0.0001). The rate of HCC screening use increased from 2001 to 2010-2011 in all study populations. Subjects who had a higher income status and were aware of their infection were more likely to have undergone recent HCC screening.

CONCLUSIONSThis study showed a substantial increase in HCC screening in high-risk HBV-infected subjects from 2001 to 2010-2011. However, the HCC screening participation rate remained suboptimal despite the introduction of the nationwide screening program. Efforts should be made to identify high-risk individuals and increase attendance at HCC screening events among high-risk groups.

BACKGROUND/AIMS: Serum alpha fetoprotein (alpha-FP) measurement has a limitation to detect hepatocellular carcinoma (HCC) because it is elevated in various liver diseases. Therefore, we studied the sensitivity and specificity of high alpha-FP in the diagnosis of HCC. METHODS: We studied 253 patients with HBsAg positive liver cirrhosis prospectively. We analyzed incidence of HCC related cut-off values of serum alpha-FP levels. During the follow-up period, we analyzed sensitivity and specificity of cut-off values of alpha-FP for the diagnosis of HCC, and alpha-FP elevation rate in relation to mass size. RESULTS: One hundred and twenty-five patients had a transient elevation of alpha-FP levels above 20 ng/mL. The corresponding incidences of HCC were 27.2% (34/125) and 15.6% (20/128 patients without elevation of alpha-FP), respectively with a statistically significant difference (p=0.03). Among 54 patients with HCC, 18 patients (33.0%) had levels of alpha-FP below 20 ng/mL on the time of diagnosis of HCC. When we defined cut-off values of serum alpha-FP as 20, 100 and 500 ng/mL, the corresponding sensitivity and specificity for HCC were 62.9% and 24.0%, 7.4% and 54.2%, 77.3% and 91.9%, respectively. We studied sensitivity according to cut-off values of alpha-FP defined as 20, 100, 200, 500 ng/mL in patients with small HCC below 2 cm. The corresponding sensitivity were 50.0%, 43.7%, 25.0%, 18.7%, respectively. In patients with levels of serum alpha-FP below 20 ng/mL, percentages of mass size less than 2 cm, 2~3 cm, 3~5 cm and more than 5 cm were 50.0%, 25.0%, 28.5% and 25.0%, respectively. CONCLUSIONS: We suggested that in order to detect HCC, careful periodic monitoring with alpha-FP, ultrasonography and abdominal computed tomography is needed in patients with HBsAg positive liver cirrhosis and whose serum level of alpha-FP is above 20 ng/mL.

BACKGROUND/AIMS: Serum alpha-fetoprotein (AFP) is frequently used for the diagnosis of hepatocellular carcinoma (HCC). Most available data concerning AFP came from studies of patients with chronic hepatitis B or mixed etiologies. Studies concerning the diagnostic value of AFP for HCV-related liver cirrhosis (LC) are limited. We evaluated the factors influencing AFP elevation in the absence of HCC and analyzed the diagnostic value of serum AFP in HCC surveillance of HCV-related LC patients. METHODS: We enrolled 55 patients of HCV-related LC with HCC and 62 patients without HCC as a case-control study were analyzed. The sensitivity and specificity were calculated and the clinical and biochemical factors influencing serum AFP levels. RESULTS: The sensitivities and specificities of serum AFP for the detection of HCC in HCV-related LC were 72.7% and 59.7% for AFP> or =20 ng/mL, and 47.3% and 92.5% for AFP> or =100 ng/mL, respectively. Elevated serum AST was independently associated with elevated serum AFP level in HCV-related LC. In cases of AST< or =2 x upper limit of normal (ULN), the specificity of AFP> or =100 ng/mL for the diagnosis of HCC was 100%. However, in case of AST>2 x ULN, the specificity was 85.0% for AFP> or =100 ng/mL and 95.0% for AFP> or =200 ng/mL. CONCLUSIONS: Serum AST levels influence serum AFP level in HCV-related LC. In cases of AST< or =2 x ULN, AFP greater than 100 ng/mL highly indicates HCC in HCV-related LC, but not in case of AST>2 x ULN.

Dermatomyositis is an idiopathic inflammatory myopathy with typical cutaneous manifestations. It has been proposed that dermatomyositis may be caused by autoimmune responses to viral infections. Previous studies have shown an association between dermatomyositis and malignant tumors such as ovarian cancer, lung cancer, and colorectal cancer. However, a chronic hepatitis B virus (HBV) infection associated with dermatomyositis and hepatocellular carcinoma (HCC) has been very rarely reported. Here, we report a rare case of dermatomyositis coinciding with HBV-associated HCC. A 55-year-old male was confirmed to have HCC and dermatomyositis based on proximal muscle weakness, typical skin manifestations, elevated muscle enzyme levels, and muscle biopsy findings. This case suggests that HCC and/or a chronic HBV infection may be factors in the pathogenesis of dermatomyositis through a paraneoplastic mechanism.

OBJECTIVETo investigate the role of absent ductular reaction (DR) at hepatocellular-stromal boundaries in early stage hepatocellular carcinoma (HCC) with cirrhosis in patients with chronic hepatitis B.

METHODSCytokeratin (CK)7 and CK19 expression was detected by the SP immunohistochemistry method in 112 hepatic nodules taken from 20 cases of early HCC, 26 cases of HCC with nodules more than 3 cm, 20 cases of high-grade dysplastic nodule (HGDN), 26 cases of low-grade dysplastic nodule (LGDN), and 20 cases of cirrhosis (CIR). DR/CK7 and DR/CK19 were assessed separately on a semi-quantitative scale and statistically analyzed.

RESULTSThe mean age of the patients in the study was 53.71 years-old, and the study population consisted of 73 males and 39 females. The follow-up time ranged from 3 to 90 months. Positive CK7 and CK19 staining was detected in the cytoplasm of DR-positive hepatobiliary cells, interlobular bile duct, and a portion of hepatic cells. All of the DR/CK7- and DR/CK19-positive cells were localized around the non-invasive nodules. Specimens with focal or diffuse DR/CK7- and DR/CK19-loss had more robust stromal invasion. Specimens from early HCC cases showed greater DR/CK19 loss than specimens from HGDN cases, LGDN cases and CIR cases (all P less than 0.01). DR/CK7 loss of early HCC was less than HCC with nodules more than 3 cm (P less than 0.05), and more than LGDN cases and CIR cases (both P less than 0.01).The area under the receiver operating characteristic curve of DR/CK7 was very similar to that of DR/CK19 (P more than 0.05). Pearson's correlation analysis indicated that DR/CK7 and DR/CK19 were positively correlated with tumor-free time (P less than 0.01) and negatively correlated with early recurrence time as well as death rate (both P less than 0.01). Furthermore, cases showing DR/CK7 or DR/CK19 loss had lower overall survival rate and tumor-free survival rate (P less than 0.01) and higher early recurrence rate (P less than 0.01).

CONCLUSIONDR/CK7 and DR/CK19 immunostaining may help to distinguish non-invasive HGDNs from both minimally-invasive and overtly-invasive HCCs by identifying small foci of invasion and predicting increased risk of invasiveness.
