BACKGROUND: Oesophageal cancer is one of the most common malignancies worldwide,and oesophageal squamous cell carcinoma (ESCC) is the predominant histological type both globally and in China. Collagen triple helix repeat containing 1 (CTHRC1) has been found to be upregulated in ESCC. However, its role in tumourigenesis and progression of ESCC remains unclear. METHODS: Using our previous ESCC mRNA profiling data, we screened upregulated genes to identify those required for proliferation...

Alcohol is a major risk factor for oesophageal squamous cell carcinoma (OSCC), the most prevalent histological subtype of oesophageal cancer (OC) worldwide. The metabolism of alcohol is regulated by specific enzymes whose activity and expression is influenced by genetic polymorphisms. We conducted a systematic review of current epidemiological evidence of the relationship between alcohol intake and OC risk, including the role of tobacco smoking and functional polymorphisms of dehydrogenases (ADHs) and aldehyde dehydrogenases (ALDHs)...

A 50-year-old male with a 7 month history of progressive dysphagia to solids then subsequently to liquids. He underwent a diagnostic gastroscopy which was normal. A further barium swallow suggested achalasia. He was referred to a tertiary centre, where he underwent pH and manometry studies which confirmed a diagnosis of achalasia. He was referred for a laparoscopic cardiomyotomy, and at surgery there was a suspected tumour at the gastro-oesophageal junction. A follow-up endoscopy with biopsies was normal...

Oesophageal cancer (OC) is associated with high morbidity and mortality, and surgery is the most effective approach to treat it. In order to reduce surgical risks and duration of surgery, we explored a new strategy to determine tumour margins in surgery. In this study, we included 128 cancerous and 128 noncancerous database entries obtained from 32 human patients. Using internal extractive electrospray ionization-MS, in positive ion detection mode, the relative abundances of m/z 104.13, m/z 116.10, m/z 132...

Larynx is the second most common site for cancer in the upper aerodigestive tract. One of the dreaded complications following total laryngectomy has been pharyngo cutaneous fistula (PCF). PCF merits special attention due to its significant negative impact on the recovery process. Total laryngectomy profoundly alters speech. Effective voice restoration is essential for the rehabilitation of these patients. Inadequate consensus exists as to the best technique of pharyngeal repair to decrease incidence of PCF and ensure good quality voice following total laryngectomy...

Development of simple and inexpensive method for the analysis of gene-specific DNA methylation is important for the diagnosis and prognosis of patients with cancer. Herein, we report a relatively simple and inexpensive electrochemical method for the sensitive and selective detection of gene-specific DNA methylation in oesophageal cancer. The underlying principle of the method relies on the affinity interaction between DNA bases and unmodified gold electrode. Since the affinity trend of DNA bases towards the gold surface follows as adenine (A) > cytosine (C) > guanine (G)> thymine (T), a relatively larger amount of bisulfite-treated adenine-enriched unmethylated DNA adsorbs on the screen-printed gold electrodes (SPE-Au) in comparison to the guanine-enriched methylated sample...

Ovarian cancer remains the leading cause of death from a gynecologic malignancy, and treatment of this disease is harder than any other type of female reproductive cancer. Improvements in the diagnosis and development of novel and effective treatment strategies for complex pathophysiologies, such as ovarian cancer, require a better understanding of disease emergence and mechanisms of progression through systems medicine approaches. RNA-level analyses generate new information that can help in understanding the mechanisms behind disease pathogenesis, to identify new biomarkers and therapeutic targets and in new drug discovery...

Synchronous primary tumours of the aerodigestive tract presenting with different histologies is a very rare event. A case with such an association is presented here. A 50-year-old lady presented with symptoms of abdominal obstruction like abdominal pain, distention and vomiting since one month. Her radiological imaging and biopsies revealed a primary oesophageal squamous cell carcinoma and primary gastric adenocarcinoma. Western medical literature has shown the occurrence of multiple synchronous cancers; however, cases from India have seldom been reported...

The objective of this study was to compare the efficacy and mechanism of lyophilized black raspberries (BRB) versus the combination of celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor, and S,S'-1,4-phenylene-bis(1,2-ethanediyl)bis-isothiourea (PBIT), a selective inducible nitric oxide synthase (iNOS) inhibitor in inhibition of carcinogen-induced esophageal squamous cell carcinoma in rats. Our data indicated that tumor multiplicity and histologic grade of esophageal precancerous lesions were reduced in animals fed BRB compared to those fed celecoxib + PBIT...

Various domestic or industrial chemicals may cause significant upper aerodigestive tract burns. Preventive measures should be up-scaled, especially in the developing world, to reduce the epidemic of accidental victims, largely unsupervised preschool children. External signs do not predict degree of injury. Non-invasive diagnostic screening includes radio-nuclear imaging, but early oesophago-gastroduodenoscopy remains the standard to predict stricture formation from circumferential submucosal scarring. Serial dilation is the mainstay of oesophageal stricture therapy, with oesophageal replacement reserved for severe refractory strictures...

Approximately half of the world's 500,000 new oesophageal squamous-cell carcinoma (ESCC) cases each year occur in China. Here, we show whole-genome sequencing of DNA and RNA in 94 Chinese individuals with ESCC. We identify six mutational signatures (E1-E6), and Signature E4 is unique in ESCC linked to alcohol intake and genetic variants in alcohol-metabolizing enzymes. We discover significantly recurrent mutations in 20 protein-coding genes, 4 long non-coding RNAs and 10 untranslational regions. Functional analyses show six genes that have recurrent copy-number variants in three squamous-cell carcinomas (oesophageal, head and neck and lung) significantly promote cancer cell proliferation, migration and invasion...

We report a simple colorimetric (naked-eye) and electrochemical method for the rapid, sensitive and specific quantification of global methylation levels using only 25 ng of input DNA. Our approach utilises a three-step strategy; (i) initial adsorption of the extracted, purified and denatured bisulfite-treated DNA on a screen-printed gold electrode (SPE-Au), (ii) immuno-recognition of methylated DNA using a horseradish peroxidase (HRP)-conjugated methylcytosine (HRP-5mC) antibody and (iii) subsequent colorimetric detection by the enzymatic oxidation of 3,3',5,5'-tetramethylbenzidin (TMB)/H2O2 which generated a blue-coloured product in the presence of methylated DNA and HRP-5mC immunocomplex...

The Polycomb group (PcG) genes are a general class of regulators that are responsible for maintaining homeotic gene expression throughout cell division. PcG expression plays an important role in oncogenesis of several types of human cancer. Mel-18 and Bmi-1 are key PcG proteins. Studies have shown that Mel-18 is a potential tumour suppression and Bmi-1 is overexpressed in several human malignancies. However, the roles of Mel-18 and Bmi-1 in oesophageal squamous cell carcinoma (ESCC) are still unclear. In this study, we analysed the expression levels of Mel-18 and Bmi-1 in 89 oesophageal cancer tissues and paired normal mucosal tissues using immunohistochemistry, Western blotting and quantitative real-time PCR (QRT-PCR) analyses...

Trimodal therapy consisting of neoadjuvant chemoradiation followed by esophagectomy has become the standard of care in North America for locally advanced esophageal cancer. While cisplatin/5-fluorouracil has been a common concurrent chemotherapy regimen since the 1980s, its utilization has declined in recent years as the Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) trial regimen of carboplatin/paclitaxel has become widely adopted. The efficacy of the CROSS regimen compared to alternate chemotherapy choices, however, has rarely been evaluated when each is used as a component of a trimodal treatment approach...

Gamma-glutamyltransferase (GGT) is a marker for hepatic injury and alcohol consumption. However, the association of GGT with the risk of oesophageal carcinoma (OC) has not been fully recognized to date. Therefore, this study aimed to determine the association between elevated GGT and OC, by also considering the body mass index (BMI) of the subjects. Clinical data from 8,388,256 Korean individuals, who were aged 40 years and over and who received healthcare check-ups arranged by the national insurance program in 2007 and 2008, were analysed...

BACKGROUND: Right para-oesophageal lymph nodes (RPELN) are included among the right central compartment lymph nodes (rCLN) and located behind right recurrent laryngeal nerve (rRLN). However, due to the likelihood of increasing postoperative complications, and the extremely difficulties of RPELN dissection, the decision to perform RPELN dissection remains controversial. The aim of this study was to explore the risk factors of RPELN metastasis and evaluate RPELN metastasis by preoperative examination...
