Background Head and neck is one of the most prevalent site for cancers along with lungs, cervix, breast and stomach. Hospital based cancer registries required for effective evaluation of diagnosis and management of cancer is inadequate in Nepal. Cancer registry system established by WHO is acquired by seven major hospitals in our country. However, data from tertiary health care centres like ours remain undocumented. Objective The objective of this study is to perform retrospective analysis of clinicohistopathological types of head and neck lesions which were eventually diagnosed as cancer in Dhulikel Hospital, a tertiary health care centre of Central East Nepal...

The presence of toxic metals in soil per se, and in soil impacted by mining, industry, agriculture and urbanisation in particular, is a major concern for both human health and ecotoxicology. The dual aim of this study was: to ascertain whether topsoil composition could influence the spatial distribution of mortality due to different types of cancer and to identify possible errors committed by epidemiological studies which analyse soil composition data as a closed number system. We conducted an ecological cancer mortality study, covering 861,440 cancer deaths (27 cancer sites) in 7917 Spanish mainland towns, from 1999 to 2008...

BACKGROUND: Patients with Barrett's oesophagus may be at increased risk of mortality overall, and cardiovascular disease has been suggested as the main underlying cause of death. AIM: To examine cause-specific mortality and risk of cardiovascular events among patients with Barrett's oesophagus. METHODS: Utilising existing Danish data sources (1997-2011), we identified all patients with histologically verified Barrett's oesophagus (n = 13 435) and 123 526 members of the general population matched by age, sex and individual comorbidities...

The increased risk of subsequent primary malignancies (SPM) in survivors of adult-onset Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) remains a challenging clinical problem worldwide. The German cancer registry database, pooled from 14 federal states, was used to calculate the standardized incidence ratio (SIR) and excess absolute risk (EAR) of SPM in 128 587 patients registered with first primary HL/NHL between 1990 and 2012. Conversely, SIRs were also calculated for a subsequent HL/NHL following other first cancers...

BACKGROUND: Raised levels of systemic inflammatory markers are associated with poor survival in patients with cancer. The aim of this study was to assess the prognostic value of markers of systemic inflammation in patients with adenocarcinoma of the oesophagus or gastro-oesophageal junction. METHODS: Data from a consecutive series of patients undergoing transthoracic oesophagectomy following neoadjuvant therapy at a single centre were analysed. Fibrinogen, albumin, C-reactive protein, leucocyte differential and platelet counts were measured before surgery...

Oesophageal cancer affects more than 450000 people worldwide and despite continued medical advancements the incidence of oesophageal cancer is increasing. Oesophageal cancer has a 5 year survival of 15%-25% and now globally attempts are made to more aggressively diagnose and treat Barrett's oesophagus the known precursor to invasive disease. Currently diagnosis the of Barrett's oesophagus is predominantly made after endoscopic visualisation and histopathological confirmation. Minimally invasive techniques are being developed to improve the viability of screening programs...

Helicobacter pylori is an important human pathogen, associated with a substantial burden from both malignant and non-malignant diseases. The bacterium is classed as a human carcinogen, being strongly linked with gastric cancer, the third most common cause of cancer death worldwide and is also associated with common conditions such as dyspepsia and peptic ulcer. Eradication of H. pylori reduces the incidence of gastric cancer and peptic ulcer, as well as the prevalence and costs of managing dyspepsia. Economic analyses suggest that eradication of H...

OBJECTIVE: Barrett's oesophagus (BE) increases the risk of oesophageal adenocarcinoma by 10-55 times that of the general population, but no community-based cancer-specific incidence and cause-specific mortality risk estimates exist for large cohorts in the USA. DESIGN: Within Kaiser Permanente Northern California (KPNC), we identified patients with BE diagnosed during 1995-2012. KPNC cancer registry and mortality files were used to estimate standardised incidence ratios (SIR), standardised mortality ratios (SMR) and excess absolute risks...

Oesophageal cancers are prominent worldwide; however, there are few targeted therapies and survival rates for these cancers remain dismal. Here we performed a comprehensive molecular analysis of 164 carcinomas of the oesophagus derived from Western and Eastern populations. Beyond known histopathological and epidemiologic distinctions, molecular features differentiated oesophageal squamous cell carcinomas from oesophageal adenocarcinomas. Oesophageal squamous cell carcinomas resembled squamous carcinomas of other organs more than they did oesophageal adenocarcinomas...

Hyperglycaemic influence on carcinogenesis and tumour progression is emerging as a link between diabetes and cancer. This work establishes the disturbed structural integrity of nucleosomal linker histone H1 by methyglyoxal (MG) and then correlates the role of modified H1 in the auto-immunopathogenesis of multiple cancers. MG modification caused a loss of free ε-amino groups in H1 and raised its β-sheet structural component with a consequence of non amyloid aggregation. It changed the folding-unfolding denaturation pattern of H1 and attached itself to the lysine residues of the protein eventually making up N(ε)-(carboxyethyl) lysine...

INTRODUCTION: There is a growing interest in the study of radiation-induced secondary cancer. The aim of this work is (i) to estimate the peripheral doses attributable to intensity modulated radiotherapy (IMRT) and mega-voltage cone beam computed tomography (MV-CBCT) for some organs at risk (OARs) which surround the target being treated (Nasopharynx) in paediatric patients. (ii) To estimate the risk of radiation-induced secondary cancers attributable to patient setup verification imaging dose using MV-CBCT for Nasopharyngeal Carcinoma (NPC) in paediatric patients and comparing it with that attributable to the therapeutic dose using IMRT...

There has been a rapid increase in the incidence of oesophageal adenocarcinoma in most Western countries over the past thirty years. Barrett's oesophagus (BE) is a common premalignant lesion of oesophageal adenocarcinoma, although the risk of developing cancer in BE remains low. Therefore, screening is not recommended in the general population. Surveillance of BE is recommended to detect high grade dysplasia or carcinoma in an early stage, although there is no clear evidence that surveillance leads to a reduced mortality...

Gastrointestinal (GI) diseases are among the leading causes of death in the world. To reduce the burden of GI diseases, surveillance is recommended for some diseases, including for patients with inflammatory bowel diseases, Barrett's oesophagus, precancerous gastric lesions, colorectal adenoma, and pancreatic neoplasms. This review aims to provide an overview of the evidence on cost-effectiveness of surveillance of individuals with GI conditions predisposing them to cancer, specifically focussing on the aforementioned conditions...

INTRODUCTION: Barrett's oesophagus (BO), a metaplastic condition affecting the lower oesophagus due to long-standing gastro-oesophageal reflux and chronic inflammation, is a precursor lesion for oesophageal adenocarcinoma (OADC). There is no clinical test to predict which patients with BO will progress to OADC. The British Society of Gastroenterology recommends endoscopic surveillance of patients with BO. Epigenetic changes have been well characterised in the neoplastic progression of ulcerative colitis to colonic carcinoma, another gastrointestinal cancer associated with chronic inflammation...

Complete pharyngo-oesophageal stricture (PES) after radiotherapy for head and neck cancer is a relatively rare and difficult complication to manage. Historically this condition has been treated surgically, but endoscopic approaches are now available. We present a 61-year-old man with an epidermoid carcinoma of the supraglottic stage and a micro-invasive epidermoid carcinoma of the oropharynx treated surgically and subsequently by adjuvant radiotherapy. Eight months after the end of the radiotherapy, a complete PES was diagnosed and treated with a combined anterograde-retrograde endoscopic dilation (CARD)...

Bile acids are components of gastro-duodenal refluxate and regarded as causative agents in oesophageal disease but the precise mechanisms are unknown. Here we demonstrate that a specific subset of physiological bile acids affect the protein secretory pathway by inducing ER stress, activating the Unfolded Protein Response (UPR) and causing disassembly of the Golgi apparatus in oesophageal cells. Deoxycholic acid (DCA), Chemodeoxycholic acid (CDCA) and Lithocholic acid (LCA) activated the PERK arm of the UPR, via phosphorylation of eIF2α and up-regulation of ATF3, CHOP and BiP/GRP78...

Cumulative relative survival curves for many cancers reach a plateau several years after diagnosis, indicating that the cancer survivor group has reached "statistical" cure. Parametric mixture cure model analysis on grouped relative survival curves provide an interesting way to determine the proportion of statistically cured cases and the mean survival time of the fatal cases in particular for population-based cancer registries. Based on the relative survival data from the Belgian Cancer Registry, parametric cure models were applied to seven cancer sites (cervix, colon, corpus uteri, skin melanoma, pancreas, stomach and oesophagus), at the Flemish Regional level for the incidence period 1999-2011...

BACKGROUND: Research on a possible causal association between alcohol consumption and risk of prostate cancer is inconclusive. Recent studies on associations between alcohol consumption and other health outcomes suggest these are influenced by drinker misclassification errors and other study quality characteristics. The influence of these factors on estimates of the relationship between alcohol consumption and prostate cancer has not been previously investigated. METHODS: PubMed and Web of Science searches were made for case-control and cohort studies of alcohol consumption and prostate cancer morbidity and mortality (ICD-10: C61) up to December 2014...
