Conventional regimens for unresectable intrahepatic cholangiocarcinoma are considered of limited effectiveness. To evaluate the efficacy and toxicity of combination chemotherapy with hepatic arterial infusion of IA-call (a fine-powder formulation of cisplatin) plus oral S-1 in patients with unresectable intrahepatic cholangiocarcinoma. The clinicopathological data and long-term outcome of 12 patients who were received with IA-call plus S-1 were compared with those of 16 patients who were received other treatments, such as radiation therapy, trans-arterial chemoembolization, and systemic chemotherapy...

Glioblastoma is the most frequent primary malignant brain tumor in adults. With the number of symptoms and signs, it belongs to diseases where a lot of treatment modalities are often applied. A standard treatment for patients with glioblastoma includes surgical resection followed by radiotherapy with concomitant and adjuvant temozolomide. Each type of treatment has its own toxicity. Temozolomide is an oral alkylating cytotoxic drug and like any other alkylating agent can induce side effects. Although temozolomide is generally a well tolerated drug, with rare severe toxic effects, sometimes certain toxicities can overcome the life risk of the underlying malignancy...

Purpose: Adoptive cell therapy (ACT) using tumor-infiltrating lymphocytes (TIL) for metastatic melanoma can be highly effective, but attrition due to progression before TIL administration (32% in prior institutional experience) remains a limitation. We hypothesized that combining ACT with cytotoxic T lymphocyte-associated antigen 4 blockade would decrease attrition and allow more patients to receive TIL. Experimental design: Thirteen patients with metastatic melanoma were enrolled...

We report a case of an 81-year-old woman with multifocal hepatocellular carcinoma who underwent transarterial chemoembolization. The patient had significant superior mesenteric artery (SMA) ostial stenosis, which led to retrograde flow in the retroportal artery to the SMA. The authors adopted several approaches to avoid potential nontarget embolization that might result from the change in the hemodynamics in the hepatoenteric arteries by initially stenting the SMA ostial stenosis as well as the use of the Surefire infusion system and balloon occlusion for delivery of chemoembolization material to tumors in the hepatic lobes...

The hepatic VX2 carcinoma model in rabbits is widely used for the preclinical study of hepatocellular carcinoma. In the present study, a modification was made to the conventional method to establish the animal model, as the conventional method gives rise to frequent tumor seeding due to the drop-out of tumor fragments. In order to evaluate each distinct method of establishing the model, the rabbits were divided into two groups: Group A (the conventional method; n=20) and group B (the modified method; n=20)...

Golgi Protein 73 (GP73) is a newly identified diagnostic and prognostic marker for liver cancer. GP73 is highly expressed in liver cancer tissues, however, the mechanism of its overexpression in tumors remains unknown. In the present study, the effect of hepatitis B virus (HBV) on GP73 expression was investigated in HepG2 cells, which are negative for HBV, and in HepG2.2.12 cells, which are integrated with HBV, using reverse transcription-quantitative polymerase chain reaction and western blot analysis. In addition, the cells were transfected with plasmid constructs overexpressing hepatitis B virus protein X (HBx), hypoxia-inducible factor (HIF)-1α, or HIF-2α in order to examine their roles in GP73 expression...

Inflammatory cells such as macrophages can play a pro-tumorigenic role in the tumor stroma. Tumor-associated macrophages (TAMs) generally display an M2 phenotype with tumor-promoting activity; however, the mechanisms regulating the TAM phenotype remain unclear. Complement 5a (C5a) is a cytokine-like polypeptide that is generated during complement system activation and is known to promote tumor growth. Herein, we investigated the role of C5a on macrophage polarization in colon cancer metastasis in mice. We found that deficiency of the C5a receptor (C5aR) severely impairs the metastatic ability of implanted colon cancer cells...

INTRODUCTION: Dorsophilia protein, mothers against decapentaplegic homolog 4 (SMAD4) is a key mediator in the transforming growth factor (TGF)-β signaling pathway and SMAD4 gene mutations are thought to play a critical role in colorectal cancer (CRC) progression. However, little is known about its influence on survival in patients undergoing resection for colorectal liver metastases (CLM). METHODS: Between 2005 and 2015, all patients with known SMAD4 mutation status who underwent resection of CLM were identified...

BACKGROUND: Human leukocyte antigen (HLA)-G is a nonclassical HLA class I molecule with modulatory effects on NK and T cells. Because HLA-G expression is frequently detected in different solid tumors, it may be involved in tumor immune evasion. OBJECTIVE: This study was designed to elucidate the prognostic value of HLA-G in hepatocellular carcinoma (HCC) and pancreatic adenocarcinoma (PADC). The influence of hepatitis B virus (HBV) infection on HLA-G expression was also evaluated in patients with HCC...

BACKGROUND: Neuroendocrine tumors (NETs) are uncommon type of cancers, also known as APUD (amine precursor uptake decarboxylation) tumors, which are becoming increasingly prevalent. Alkaline phosphatase (ALP) is a poor prognosis factor in a number of hepatic diseases. However, its distribution and prognostic value in primary hepatic neuroendocrine tumors (PHNETs) are still not clear. In this study, our aim is to investigate the correlations between ALP and clinicopathological features and prognostic factors of PHNETs...

The liver is one of the common metastatic sites for many cancers. The obstruction of sinusoids by circulating tumor cells changes liver microenvironments and is thus considered a source of hepatic metastases. To date, few studies provide detailed information, either experimentally or theoretically, concerning the changes in blood and oxygen distributions induced by the obstruction of sinusoids. In this study, we utilized a 3D porous medium-vascular tree geometric structure to mimic the hepatic lobule and studied theoretical blood flow and oxygen transport in the lobule...

Cholangiocarcinoma (CCA) is one of the most common hepatic and biliary malignancies, accounting for about 3% of all gastrointestinal tumors. GATA5 is a transcription factor capable of suppressing the development of various human cancer types. Transcriptional inactivation and CpG island (CGI) methylation of GATA3 and GATA5, two members of the GATA family of transcription factors, have been observed in some human cancers. But whether high-density CGI methylation of GATA5 is associated with the clinical course of CCA patients has not been clarified...

Coffee roasting affects the taste, color, and aroma of coffee. The Maillard reaction, a major reaction during the roasting process, produces melanoidin, which affects the overall antioxidant capacity and anti-inflammatory effects of coffee. In this experiment, coffee roasting was divided into four degrees: Light, Medium, City, and French. To examine the in vivo antioxidant and anti-inflammatory effects of coffee extracts with different roasting degrees, we used 10-week-old male C57BL/6 mice. Mice were pre-treated with coffee extracts for 10 days by oral gavage (300 mg/Kg...

OBJECTIVE: Visceral adiposity index (VAI) is a mathematical model associated with cardiometabolic risk in adults, but studies on children failed to support this association. Our group has proposed a pediatric VAI model using pediatric ranges, but it has not yet been evaluated and needs further adjustments. The objective of this study was to further adjust the proposed pediatric VAI by age, creating a new pediatric metabolic index (PMI), and assess the correlation of the PMI with insulin resistance indexes and hepatic enzymes...

A 72-year-old woman with advanced ascending colon cancer and an intraductal papillary mucinous neoplasm (IPMN) of the pancreatic head was treated by right hemicolectomy (RHC) and pylorus-preserving pancreaticoduodenectomy (PpPD). Adjuvant chemotherapy was not administered. Multimodal examinations at 5 months after surgery detected a solitary metastatic liver tumor derived from cancer of the ascending colon. Liver resection proceeded at 7 months after the first surgery. A pathological study of a surgical specimen of the liver identified a necrotic nodule that did not contain viable tumor cells...
