Synchronous multifocal tumors are common in the hepatobiliary and pancreatic system but because of similarities in their histological features, oncologists have difficulty in identifying their precise tissue clonal origin through routine histopathological methods. To address this problem and assist in more precise diagnosis, we developed a computational approach for tissue origin diagnosis based on naive Bayes algorithm (TOD-Bayes) using ubiquitous RNA-Seq data. Massive tissue-specific RNA-Seq data sets were first obtained from The Cancer Genome Atlas (TCGA) and ∼1,000 feature genes were used to train and validate the TOD-Bayes algorithm...

PURPOSE: The purpose of this study is to assess the dose of ionizing radiation caused by repeated CT scans performed to investigate non-traumatic acute abdominal conditions in young adults. METHODS: Over 26 months, we collected a cohort of patients aged 18 to 45 years who were subject to at least one urgent contrast-enhanced abdomen/pelvis CT. Patients affected with urolithiasis, HIV infection, tumors, and vascular and chronic inflammatory bowel diseases were excluded...

Molecular imaging using radiolabeled Tyrosine Kinase Inhibitors (TKI) is a promising strategy for detection and staging of EGFR-positive cancers. A novel analogue of one such TKI, Erlotinib has been developed for PET imaging by derivatizing the parent Erlotinib molecule for conjugation with the bifunctional chelator p-SCN-Bn-NOTA towards radiolabeling with (68)Ga. NOTA-Erlotinib conjugate was synthesized and characterized by NMR and ESI-MS techniques. The conjugate was radiolabeled with (68)Ga in 95±2% yield, as evidenced by HPLC characterization...

Objective: To study the association between the AKAP12 promoter methylation and recurrence of hepatocellular carcinoma. Methods: A total of 142 primary liver cancer patients underwent surgery in department of Hepatobiliary surgery in Peking University Cancer Hospital from 2003 to 2009 were selected as subjects in the survey; with the inclusion criteria as hepatocellular carcinoma, no cancer cells were observed in the surgical margin(SM) samples. All patients had neither lymph nor distant metastasis at the time of surgery, and receiving complete follow-up data for at least 3 years...

BACKGROUNDS/AIMS: The risk of malignancies in autoimmune diseases is high and is regarded to be due to immunological abnormalities, the use of immunosuppressive agents, and/or chronic inflammation. The aim of this study was to investigate the incidence and risk of malignancies in patients with autoimmune hepatitis (AIH) type 1 in Japan. METHODS: Two hundred and fifty-six patients diagnosed with AIH were enrolled. A person-year calculation was performed for AIH patients, and the numbers of expected events were clarified using data from "The Monitoring of Cancer Incidence in Japan Project" in order to examine the standard incident rate (SIR) of each type of malignancy...

OBJECTIVE: This study aimed to investigate the correlation between the transient segmental enhancement (TSE) of liver abscesses on contrast-enhanced ultrasound (CEUS) imaging and contrast-enhanced computed tomography (CT) scans. METHODS: In total, 42 abscesses in 38 patients were evaluated with real-time CEUS and contrast-enhanced CT imaging. The CT imaging and CEUS examinations were performed within one to 2 days of each other in all cases. The initial reports of the observations of TSE on CEUS scans were correlated later with the findings of TSE on contrast-enhanced CT images...

Health related quality of life (HRQOL) is increasingly recognized as an important clinical parameter and research endpoint in patients with hepatocellular carcinoma (HCC). HRQOL in HCC patients is multifaceted and affected by medical factor which encompasses HCC and its complications, oncological and palliative treatment for HCC, underlying liver disease, as well as the psychological, social or spiritual reaction to the disease. Many patients presented late with advanced disease and limited survival, plagued with multiple symptoms, rendering QOL a very important aspect in their general well being...

The objective of this study is to compare cancer risk among different generations of Middle Eastern immigrants (ME) and non-Hispanic whites (NHW) in California between 1988 and 2013. We used data from the California Cancer Registry to identify invasive primary incident cancer cases in three population groups: (i) first-generation ME immigrants, (ii) second- or subsequent-generations ME immigrants, and (iii) NHW. Proportional incidence ratio (PIR) was used to compare cancer risk of the 15 selected most common cancers in the 3 population groups taking into consideration time since immigration for first-generation ME immigrants...

The epidermal growth factor receptor (EGFR) regulates cellular expression levels of breast cancer resistance protein (humans: ABCG2, rodents: Abcg2) via its downstream signaling pathways. Drugs that inhibit EGFR signaling (e.g. tyrosine kinase inhibitors, antibodies) may lead to ABCG2-mediated drug-drug interactions (DDIs) by changing disposition of concomitantly administered ABCG2 substrate drugs. In this study we used positron emission tomography (PET)/magnetic resonance (MR) imaging to compare disposition of the model Abcg2 substrate [(11)C]erlotinib in a mouse model of hepatocyte-specific deletion of EGFR (EGFR(Δhep) mice, n = 5) with EGFR(fl/fl) control mice (n = 6), which have normal EGFR expression levels in all tissues...

Metabolomics is now widely used to characterize metabolic phenotypes associated with lifestyle risk factors such as obesity. The objective of the present study was to explore the associations of body mass index (BMI) with 145 metabolites measured in blood samples in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Metabolites were measured in blood from 392 men from the Oxford (UK) cohort (EPIC-Oxford) and in 327 control subjects who were part of a nested case-control study on hepatobiliary carcinomas (EPIC-Hepatobiliary)...

We evaluated the association between histologic grade of hepatocellular carcinoma (HCC) and degree of HCC enhancement on Gd-EOB-DTPA (Gadoxetic acid, Primovist)-enhanced magnetic resonance images (MRI) in HCC patients.A total of 121 patients who underwent curative surgical resection for HCC at our institution between January 2012 and March 2015 were retrospectively analyzed. Gadoxetic acid enhanced MRI was performed in all patients before surgery. Signal intensities of HCC and peri-HCC areas were measured using regions of interest...

Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare and abstruse neoplasms with increasing incidence and clinical relevance. The National Cancer Data Base was examined to identify GEP-NET cases from 2004 to 2013. In total, 39,454 patients diagnosed with GEP-NET were identified. Median age was 61 years. Majority was female (50.13%), white (79.49%), and had low-grade neoplasms (84.39%). On univariate analysis, age, sex, race, primary site, tumor size, and regional lymph node involvement were associated with tumor grade (P < 0...

Gastrointestinal (GI) cancers such as gastric, esophageal, pancreas, hepatobiliary, colorectal and anal cancers are a major cause of cancer related mortality worldwide. Traditional treatment options such as chemotherapy, surgery, radiation therapy, monoclonal antibodies and anti-angiogenic agents have been the backbone of treatment of GI cancers in various stages. Current cancer research is moving forward to incorporate immunotherapies in the treatment of GI cancers either as single agent or in combination with current available treatment modalities...

BACKGROUND: European liver fluke Opisthorchis felineus, causing opisthorchiasis disease, is widespread in Russia, Ukraine, Kazakhstan and sporadically detected in the EU countries. O. felineus infection leads to hepatobiliary pathological changes, cholangitis, fibrosis and, in severe cases, malignant transformation of bile ducts. Due to absence of specific symptoms, the infection is frequently neglected for a long period. The association of opisthorchiasis with almost incurable bile duct cancer and rising international migration of people that increases the risk of the parasitic etiology of liver fibrosis in non-endemic regions determine high demand for development of approaches to opisthorchiasis detection...
