We encountered a rare case of metastatic brain tumors in the bilateral cerebellopontine angles. The patient was a 61-year-old man, who visited an otorhinolaryngology clinic with complaints of rapidly progressing bilateral hearing impairment and facial palsy. The patient was referred to our hospital because tumorous lesions were suspected in the bilateral cerebellopontine angles on brain magnetic resonance imaging. Regarding tumor markers, the patient's cancer antigen 19-9 and carcinoembryonic antigen levels were high, which suggested metastasis...

BACKGROUND: The liver fluke Opisthorchis viverrini, highly prevalent in Southeast Asia, is an important public health burden, including a risk factor for developing an aggressive bile duct cancer, cholangiocarcinoma, in chronically infected patients. Praziquantel, administered at single 40 mg/kg in preventive chemotherapy programs and 3 x 25 mg/kg for individual treatment is the drug of choice, yet information on the nature of the dose-response relationship is lacking. METHODS: We performed a randomized, parallel, single blind dose-ranging Phase 2 trial in Lao PDR in O...

Wilms tumor 1 (WT1) is considered to be a promising target of cancer treatment because it has been reported to be frequently expressed at high levels in various malignancies. Although WT1-targeted cancer treatment has been initiated, conclusive detection methods for WT1 are not established. The present study aimed to consolidate immunohistochemistry for WT1 with statistical basis. Transfected cells with forced WT1 expression yielded specific western blot bands and nuclear immunostaining; cytoplasmic immunostaining was not specifically recognized...

Despite considerable advances in understanding hepatocellular carcinoma, it is one of the common and deadliest cancers worldwide. Hence, increasing efforts are needed for early diagnosis and effective treatments. Saffron has been recently found to inhibit growth of liver cancer in rats. The aim of this study was to develop an effective method for treatment of liver cancer using magnetite nanoparticles (MNPs) coated with crocin, the main active component of saffron. MNPs were prepared and initially coated with dextran and a cross-linker to enhance conjugation of crocin using a modified coprecipitation method...

BACKGROUND: Radical resection is an effective therapeutic method to increase the survival rate of patients with gallbladder cancer (GBC). In addition to the surgical approach, the relationships between various clinicopathologic factors and the outcome of patients with GBC remain controversial. METHODS: Clinical and laboratory examination characteristics, pathological and surgical data, and post-operative survival time of 338 patients with advanced GBC who received treatment at the First Affiliated Hospital of Xi'an Jiaotong University, China from January 2008 to December 2012 were analyzed retrospectively...

BACKGROUND: Because of its high rate of early recurrence and its poor prognosis, long-term survival after cholangiocarcinoma is rare; therefore, only limited information on patients surviving more than 5 years after surgical therapy is available. CASE PRESENTATION: We report the case of a 57-year-old white man who developed a distal bile duct carcinoma 9 years after curative surgical therapy of intrahepatic cholangiocarcinoma. He had undergone a right lobe hemihepatectomy 11 years ago...

Between the years of 2010-2012, it was estimated there were a total of 112,392 new cases of cancers in Thailand, thus, the total age-standardized rate (ASR) per 100,000 is 137.6. In regards to the most prevalent types of cancer in female, breast cancer has the highest ASR, followed by cervical cancer (ASR=14.4); liver and bile duct cancer; colon and rectum cancer; trachea, bronchus and lung cancer; ovarian cancer (ASR=6.0); thyroid cancer; non-Hodgkin lymphoma and uterine cancer (ASR=4.3). The trend of cervical cancer in Thailand is decreasing, one key factor in making this possible was the employment of dual tract strategy (Pap smear and visual inspection with acetic acid [VIA]) by the government in 2005...

Gastrointestinal (GI) cancers are the leading cause of mortality worldwide. These cancers are the end result of a complex interplay between gene and environment. Bacteria, parasites, and viruses have been implicated in some cancers. Recent data have put at focus the gut microbiome as the key player firing tumorigenesis. Experimental and human studies have provided evidence on the role of microbiota in cancer development. Although subject to changes in different settings such as antibiotic treatment, diet or lifestyle, our microbiome is quite stable and is capable of increasing susceptibility to cancer or decrease and halt its progression...

Surgical resection remains the most important treatment for patients with biliary tract cancer (BTC), but despite radical surgical techniques many patients ultimately develop recurrent disease. BTC encompasses several distinct disease entities-intrahepatic, perihilar and distal bile duct cholangiocarcinoma as well as gallbladder cancer. These tumors are histologically similar, but have different etiologies and recent information regarding their genomic footprint has questioned their biological similarity. Surgical approaches are also necessarily varied based on the site of the tumor...

Cholangiocarcinoma (CCA) is a relatively rare malignancy of the intra- or extra-hepatic bile ducts that is classified according to its anatomical localization as intrahepatic, perihilar or distal. Overall, CCA has a dismal prognosis due to typical presentation at an advanced irresectable stage, lack of effective non-surgical treatments, and a high rate of disease recurrence. CCA frequently arises on a background of chronic liver inflammation and cholestasis. Chronic inflammation is accompanied by enhanced cell turnover with generation of additional inflammatory stimuli, and a microenvironment rich in pro-inflammatory mediators and proliferative factors that enable accumulation of mutations, transformation and expansion of mutated cells...

BACKGROUND: Periampullary cancer includes cancer of the head and neck of the pancreas, cancer of the distal end of the bile duct, cancer of the ampulla of Vater, and cancer of the second part of the duodenum. Surgical resection is the only established potentially curative treatment for pancreatic and periampullary cancer. A considerable proportion of patients undergo unnecessary laparotomy because of underestimation of the extent of the cancer on computed tomography (CT) scanning. Other imaging methods such as magnetic resonance imaging (MRI), positron emission tomography (PET), PET-CT, and endoscopic ultrasound (EUS) have been used to detect local invasion or distant metastases not visualised on CT scanning which could prevent unnecessary laparotomy...

BACKGROUND: Gallbladder toxicity was reported in most motesanib studies with varying frequency and at variable times after initiation of treatment. METHOD AND RESULTS: A 44-year-old man was admitted due to severe epigastric pain. The patient was diagnosed with non-small cell lung cancer 9 months ago and received 6 cycles of chemotherapy with motesanib, paclitaxel, and carboplatin. Ultrasonography showed a large amount of sludge within gallbladder. Computed tomography scan demonstrated diffuse dilatation of biliary tree with distended gallbladder without evidence of stone and mild pancreatic swelling...

Catheter-based radiofrequency ablation (RFA) delivered during endoscopic retrograde cholangiopancreatography (ERCP) may represent a viable treatment option for intraductal extension of ampullary neoplasms, however, clinical experience with this modality is limited. After ampullary resection, 4 patients with intraductal extension underwent adjunctive RFA of the distal bile duct. All patients received a temporary pancreatic stent to reduce the risk of pancreatitis, as well as a plastic biliary stent to prevent biliary obstruction...

Armillaria mellea is a honey mushroom often used in the traditional Chinese medicine "Tianma". Currently, this medicinal mushroom is also used as a dietary supplement in numerous Western and Eastern countries. Armillarikin was isolated from A. mellea, and we previously discovered that it induced cytotoxicity in human leukemia cells. In this study, we further investigated the cytotoxicity of armillarikin against liver and intrahepatic bile duct cancer cells. Armillarikin was cytotoxic against human hepatocellular carcinoma Huh7, HA22T, and HepG2 cells based on the 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium and alamarBlue(®) assays...

BACKGROUND: Nerium oleander L. (syn. Nerium indicum Mill, Nerium odorum Aiton) belongs to the family Apocynaceae. It is used for its anti-inflammatory, anti-diabetic, anti-cancer and hepatoprotective activities in traditional medicine. Previous pharmacognostic studies suggested that 70 % hydro-methanolic extracts of oleander possess potent free radical scavenging and anti-inflammatory activities, both of which are helpful against hepatotoxicity. METHODS: Hydro-methanolic extracts of oleander stem and root were evaluated for their hepatoprotective activities in acute CCl4 intoxicated mouse through in vitro and in vivo studies...

BACKGROUND: Hepatic inflammatory pseudotumor (IPT) is a rare disease which often mimics a malignant tumor and is therefore often misdiagnosed and surgically resected. Recently, a concept of IgG4-related diseases (IgG4-RD) has been proposed that is becoming widely recognized and includes IgG4-related hepatic IPT. Corticosteroids are widely accepted as the standard treatment. CASE PRESENTATION: A 72-year-old Japanese man, who had been followed for ten years after surgery and chemotherapy for treatment of hilar and lower bile duct cancers, developed intermittent fever and abdominal pain and visited this hospital...

Opisthorchis felineus (O. felineus) occurs in Western Siberia and many other parts of the Russian Federation (RF). The true extent of its distribution is not known. Chronic infection may lead to severe hepatobiliary morbidity. According to surgical and experimental reports, long-term infestation might significantly increase the risk for cholangiocarcinoma (CCA). To date, no association between O. felineus infection and CCA has been demonstrated. The objective of this study was to review existing health data on the incidence of O...
