Detection and diagnosis of cancer are especially important for early prevention and effective treatments. Traditional methods of cancer detection are usually time-consuming and expensive. Liquid biopsy, a newly proposed noninvasive detection approach, can promote the accuracy and decrease the cost of detection according to a personalized expression profile. However, few studies have been performed to analyze this type of data, which can promote more effective methods for detection of different cancer subtypes...

Protein expression of major hepatobiliary drug transporters (NTCP, OATPs, OCT1, BSEP, BCRP, MATE1, MRPs and P-gp) in cancerous (C, n=8) and adjacent non-cancerous (NC, n=33) liver tissues obtained from chronic hepatitis C patients with hepatocellular carcinoma (HCV-HCC) were quantified by LC-MS/MS proteomics. Herein, we compare our results with our previous data from non-infected non-cirrhotic (control, n=36) and HCV-cirrhotic (n=30) livers. The amount of membrane protein yielded from NC and C HCV-HCC tissues decreased (31%, 67%) relative to control livers...

BACKGROUND: The improving efficacy of cancer treatment has resulted in an increasing array of treatment-related symptoms and associated burdens imposed on individuals undergoing aggressive treatment of their disease. Often, clinical trials compare therapies that have different types, and severities, of adverse effects. Whether rated by clinicians or patients themselves, it can be difficult to know which side effect profile is more disruptive or bothersome to patients. A simple summary index of bother can help to adjudicate the variability in adverse effects across treatments being compared with each other...

Vinflunine is to date the only registered agent for second-line treatment of metastatic urothelial cell carcinoma (UCC) in Europe. However, the effect is modest. Pemetrexed has demonstrated some single-agent activity in this disease entity. In order to improve treatment possibilities for UCC patients, a phase I trial (VINTREX) was undertaken to assess the safety of vinflunine and pemetrexed in metastatic UCC patients. A dose escalation design was planned to determine the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of a vinflunine/pemetrexed combination...

Arsenicosis, a syndrome caused by ingestion of arsenic contaminated drinking water, currently affects millions of people in South-East Asia and elsewhere. Previous animal studies revealed that the toxicity of arsenite essentially can be abolished if selenium is co-administered as selenite. Although subsequent studies have provided some insight into the biomolecular basis of this striking antagonism, many details of the biochemical pathways that ultimately result in the detoxification and excretion of arsenic using selenium supplements have yet to be thoroughly studied...

Background: The overall risk of cancer following ileal pouch-anal anastomosis [IPAA] is unknown, and pouch cancer surveillance is controversial. We evaluated long-term risk of cancer in a national cohort of patients with ulcerative colitis and IPAA, with emphasis on pouch cancer. Methods: Data on incident cancers were extracted from the national Danish Cancer Registry. Incidence rates for all site-specific cancers were compared between patients with IPAA and a gender- and age-matched comparison cohort from the background population to obtain incidence rate ratios [IRRs]...

Lynch syndrome or hereditary nonpolyposis colorectal cancer is the most common of hereditary colorectal cancer and accounts for 1-3%. Lynch and Chapelle estimated that it accounts 5-8% for all colorectal cancers. It is an autosomal dominant syndrome characterized by predisposition of various cancers (colorectal, stomach, endometrial, ovarian, renal, small bowel, and hepatobiliary tract) at earlier age than in general population and occurs as a result of mutation in DNA mismatch repair genes. This article presents a rare clinical of a 61-year-old female diagnosed with extracolonic Lynch syndrome with six metachronous tumours acquiring in digestive tract during the period from 1993 to 2014 (over 21 years)...

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...
