To examine the effects of 4-methylthio-3-butenyl isothiocyanate on esophageal carcinogenesis, male 6-week-old F344 rats were subcutaneously injected with 0.5 mg/kg body weight N-nitrosomethylbenzylamine three times per week for 5 weeks and fed a diet supplemented with 80 ppm 4-methylthio-3-butenyl isothiocyanate, equivalent to 6.05 mg/kg body weight/day for the initiation stage, 4.03 mg/kg body weight/day for the promotion stage, or 4.79 mg/kg body weight/day for all stages. Although the incidence of lesions was not affected by 4-methylthio-3-butenyl isothiocyanate treatment, the multiplicity of squamous cell papilloma in the esophagus was significantly decreased in rats in the 4-methylthio-3-butenyl isothiocyanate initiation stage group (1...

Aberrant methylation of DNA is a common event in the development of cancers, including squamous cell carcinoma (SCC) of the human esophagus. In the present study, we determined: (a) whether aberrant DNA methylation also occurs in the development of N-nitrosomethylbenzylamine (NMBA)-induced tumorigenesis in the rat esophagus, a model of human esophageal SCC; and (b) if so, whether dietary black raspberries (BRBs) are capable of preventing this aberrant DNA methylation. A diet containing 5% BRBs inhibited the development of NMBA-induced tumors in the rat esophagus...

CONTEXT: To identify the incidence of human papilloma virus (HPV) infection in squamous esophageal cancer. AIMS: To identify high-risk (HR) HPV positivity rates in patients with squamous carcinoma esophagus and to compare their characteristics with HPV negative counterparts. SETTINGS AND DESIGN: A prospective study, in which tumor biopsies of 18 consecutive patients with squamous carcinoma of the esophagus treated with definitive chemo-radiotherapy (CT-RT) were evaluated for the presence of HPV...

BACKGROUND AND AIMS: There has been a recent increase in the incidence of oropharyngeal cancer (OPC) associated with high-risk human papilloma virus (HPV) infection. We investigated the incidence of esophageal papilloma and the presence of high-risk HPV infection. METHODS: This is a cross-sectional study conducted at a County teaching hospital. Patients with esophageal papilloma between January 2000 and December 2013 were identified. Patients with sufficient specimens were tested for the HPV virus...

AIM: To better understand some of the superficial tiny lesions that are recognized as squamous papilloma of the esophagus (SPE) and receive a different pathological diagnosis. METHODS: All consecutive patients with esophageal polypoid lesions detected by routine endoscopy at our Endoscopy Centre between October 2009 and June 2014 were retrospectively analysed. We enrolled patients with SPE or other superficial lesions to investigate four key endoscopic appearances (whitish color, exophytic growth, wart-like shape, and surface vessels) and used narrow band imaging (NBI) to distinguish their differences...

BACKGROUND: Esophageal squamous cell carcinoma (ESCC) is a common cancer in the north east of India. The present study concerned the prevalence of human papilloma virus (HPV) in the ESCC in north eastern India and its impact on response to chemotherapy. MATERIALS AND METHODS: p16 expression, a surrogate marker for HPV infection was assessed in 101 pre-treatment biopsies of locally advanced ESCC, reported from a comprehensive cancer centre in north east India, using immunohistochemistry...

BACKGROUND: Cancers are the second most common cause of non-accidental deaths in Iran, after cardiovascular mortality. Although most cases of esophageal squamous cell carcinoma (ESCC) in the USA and western populations have been attributed to high levels of exposure to tobacco and alcohol, but in Iranian populations, other risk factors especially infectious agents have been postulated as possible causes, particularly human papillomavirus (HPV). This study aimed to determine the prevalence and the types of HPV infection in biopsy samples taken from non-cancerous esophageal lesions during upper endoscopy...

INTRODUCTION: Given the difficulty in accessing to the excluded stomach after gastric bypass and the increase in gastroesophageal reflux after sleeve gastrectomy, it is justified to perform a preoperative fibrogastroscopy.The influence of the fibrogastroscopy (FGS) findings in the therapeutic approach is analyzed. PATIENTS AND METHODS: A retrospective study of preoperative FGS findings is performed, from 04/06 to 12/12. The influence of the FGS results on the surgical technique selection, in the endoscopic or medical treatment and its relation to gastric fistula is analyzed by means of multivariate regression (confounding factors: Age, body mass index, arterial hypertension, diabetes mellitus, antiplatelet therapy, surgical technique (bariatric surgery, sleeve gastrectomy)...

BACKGROUND AND STUDY AIMS: Esophageal squamous papilloma (ESP) is a rare lesion. The aims of this study were to assess the prevalence of ESP in northeastern France and the risk of associated squamous cell carcinoma (SCC). PATIENTS AND METHODS: The charts of 78 patients who were diagnosed with ESP between January 2005 and February 2013 at three hospitals in northeastern France were reviewed. RESULTS: A total of 55 305 endoscopies were performed and 78 ESP were diagnosed (0...

Cyclin D1 is frequently overexpressed in esophageal squamous cell carcinoma (ESCC) and is considered a key driver of this disease. Mutations in FBXO4, F-box specificity factor that directs SCF-mediated ubiquitylation of cyclin D1, occur in ESCC with concurrent overexpression of cyclin D1 suggesting a potential tumor suppressor role for FBXO4. To evaluate the contribution of FBXO4-dependent regulation cyclin D1 in esophageal squamous cell homeostasis, we exposed FBXO4 knockout mice to N-nitrosomethylbenzylamine (NMBA), an esophageal carcinogen...

A polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was developed to detect and type bovine papillomaviruses (BPVs) from tumors in cattle. Two degenerate primer sets targeting the BPV L1 gene, subAup/subAdw and subBup/subBdw, and one restriction enzyme RsaI were used in this assay. In silico analyses of the restriction enzyme sites in the PCR fragments of 13 BPV sequences (BPV-1 to -13) revealed that all known BPVs are differentiated by the PCR-RFLP assay. Analyses of 63 previously typed clinical samples, that included teat papillomas and both esophageal and urinary bladder cancer biopsies, show that the assay clearly differentiates between eight clinically important BPV types (BPV-1 to -6, -9, -10), and discriminates between single and multiple infections...

Squamous papilloma of the esophagus is a rare benign lesion of the esophagus. Radiofrequency ablation is an established endoscopic technique for the eradication of Barrett esophagus. No cases of endoscopic ablation of esophageal papilloma by radiofrequency ablation (RFA) have been reported. We report a case of esophageal papilloma successfully treated with a single session of radiofrequency ablation. Endoscopic ablation of the lesion was achieved by radiofrequency using a new catheter inserted through the working channel of endoscope...

Worldwide, approximately 5 to 10% of the population is infected by a Human Papilloma Virus (HPV). Some of these viruses, with a high oncogenic risk (HPV HR), are responsible for about 5% of cancer. It is now accepted that almost all carcinomas of the cervix and the vulva are due to an HPV HR (HPV16 and 18) infection. However, these viruses are known to be involved in the carcinogenesis of many other cancers (head and neck [SCCHN], penis, anus). For head and neck cancer, HPV infection is considered as a good prognostic factor...

Benign esophageal lesions have a wide spectrum of clinical and pathologic features. Understanding the endoscopic and pathologic features of esophageal lesions is essential for their detection, differential diagnosis, and management. The purpose of this review is to provide updated features that may help physicians to appropriately manage these esophageal lesions. The endoscopic features of 2997 patients are reviewed. In epithelial lesions, the frequency of occurrence was in the following order: glycogenic acanthosis, heterotopic gastric mucosa, squamous papilloma, hyperplastic polyp, ectopic sebaceous gland and xanthoma...
