LS values at CVR are useful for predicting forthcoming LRE development. Thus, in the era of potent antiviral therapy, tailored surveillance strategies might be established based upon LS values at CVR.

AIMS: The prognosis of metaplastic breast cancer (MBC) is reportedly worse than that of triple-negative invasive ductal carcinoma (TN-IDC), but the determinants of poor prognosis are not yet known. METHODS: Patients from two Korean cancer centres were included in this study (67 MBC and 520 TN-IDC). Characteristics of the two disease groups, including clinical parameters, histological features, chemoresponsiveness, disease recurrence and survival estimates, were evaluated. RESULTS: MBC presented

Chronic hepatitis B virus (HBV) infection is a major global health problem. It can cause progressive liver fibrosis leading to cirrhosis with end-stage liver disease, and a markedly increased risk of hepatocellular carcinoma. In the last two decades, substantial progress has been made in the treatment of chronic hepatitis, B. However, HBV is often reactivated after stopping nucloes(t)ide analogues because antivirals alone do not directly target covalently closed circular DNA, which is the templa

This novel TE-based CLA model showed acceptable accuracy in discriminating NASH from simple steatosis. However, further studies are required for external validation.

BACKGROUND AND AIMS: Type 2 diabetes is an important risk factor for nonalcoholic fatty liver disease (NAFLD) and advanced fibrosis. Current international guidelines recommend the use of noninvasive tests as initial assessments for NAFLD, but the role of noninvasive tests as monitoring tools has not been established. We aimed to study the role of transient elastography as a monitoring tool in patients with type 2 diabetes. APPROACH AND RESULTS: We recruited patients with type 2 diabetes without

Chronic hepatitis B virus (HBV) infection is a major cause of cirrhosis and hepatocellular carcinoma (HCC). Applying the same strategies for antiviral therapy and HCC surveillance to all chronic hepatitis B (CHB) patients would be a burden worldwide. To properly manage CHB patients, it is necessary to identify and classify the risk for HCC development in such patients. Several HCC risk scores based on risk factors such as cirrhosis, age, male gender, and high viral load have been used, and have

To determine a cellular factor supporting the survival of gastric cancer cells, a comparative study was performed using two human adenocarcinoma cell lines, SNU-16 and SNU-620. The latter cells were significantly less susceptible to various lethal stimuli including anti-Fas, H(2)O(2), etoposide, and serum withdrawal than the former. These stimuli were found to kill the SNU-16 cells by activating stress-activated protein kinase (SAPK)/c-Jun NH(2)-terminal kinase (JNK), whereas SAPK/JNK activation

This report presented the subtype-specific statistical analysis of lymphoid malignancies in the Korean population, showing increasing incidences and survival rates in most subtypes.

Most patients with hepatocellular carcinoma (HCC) are diagnosed at an advanced stage of disease. Until recently, systemic treatment options that showed survival benefits in HCC have been limited to tyrosine kinase inhibitors, antibodies targeting oncogenic signaling pathways or VEGF receptors. The HCC tumor microenvironment is characterized by a dysfunction of the immune system through multiple mechanisms, including accumulation of various immunosuppressive factors, recruitment of regulatory T c

Abstract Purpose: To assess the antitumor activity and safety of tipifarnib, a highly potent and selective farnesyltransferase inhibitor, we performed a phase II clinical trial in patients with advanced and refractory urothelial carcinoma harboring missense HRAS mutations. Patients and Methods: A total of 245 adult patients with previously treated, advanced urothelial carcinoma entered the molecular screening program including HRAS. Those with missense HRAS mutations or STK11:rs2075606 received

BACKGROUND & AIMS: Precise assessment of liver fibrosis is necessary in patients with chronic liver disease. We investigated the performance of red cell volume distribution width-to-platelet ratio for the assessment of liver fibrosis in patients with chronic hepatitis B. METHODS: A total of 482 consecutive patients with chronic hepatitis B who underwent liver biopsy between October 2005 and May 2014 were recruited. Liver stiffness was measured using transient elastography. FIB-4 score, red cell

BACKGROUND AND AIMS: The modified PAGE-B (mPAGE-B) score comprising age, gender, platelet count and albumin was recently proposed to predict hepatocellular carcinoma (HCC) risk among chronic hepatitis B (CHB) patients undergoing antivirals. Here, in the independent cohort, we externally validated the predictive performance of the mPAGE-B score and compared it with those of conventional HCC prediction models. METHODS: We consecutively recruited CHB patients treated with lamivudine, entecavir or t

Our data demonstrated that VFA and TG is significantly related to hepatic steatosis assessed by CAP not BMI. This finding suggests that surveillance for subjects with NAFLD should incorporate an indicator of visceral obesity, and not simply rely on BMI.
