The molecular changes driving the carcinogenesis in Barrett's esophagus: which came first, the chicken or the egg?

2013

Esophageal adenocarcinoma originates from columnar metaplastic epithelium of the distal esophagus. Various steps for this carcinogenetic process are known. Before the onset of high-grade dysplasia and adenocarcinoma, endoscopic surveillance is possible. However, because of the high cost of long-term surveillance, predictive factors for cancer are being evaluated to identify subjects with metaplasia who have a higher risk of developing malignancy. Molecular changes seem suitable for this purpose, but could require a high resource expenditure. While trying to identify the best predictive factors for cancer risk, molecular changes and differences in miRNA expression profile between the various…

Lumevis ™: a new medical device to prepare patients for esophagogastroduodenoscopy. Experimental clinical study.

2020

Esophagogastroduodenoscopy (EGDS) is the gold standard exam for upper gastrointestinal diseases. EGDS is very important in Early Gastric Cancer diagnosis and treatment but it is an operator-dependent exam and there are lots of factors that reduce its visibility (mucus, bubbles and foam).The aim of our study is to evaluate if the use of Lumevis™ improves mucosa visualization during EGDS without increasing the examination time and complications' rate and comparing the differences in patients prepared with water or no intervention.we recruited 50 patients from 01/08/2020 to 31/08/2020 who came to our observation for epigastric pain, dyspepsia and gastroesophageal reflux (GERD).

A machine learning application to predict early lung involvement in scleroderma: A feasibility evaluation

2021

Introduction: Systemic sclerosis (SSc) is a systemic immune-mediated disease, featuring fibrosis of the skin and organs, and has the greatest mortality among rheumatic diseases. The nervous system involvement has recently been demonstrated, although actual lung involvement is considered the leading cause of death in SSc and, therefore, should be diagnosed early. Pulmonary function tests are not sensitive enough to be used for screening purposes, thus they should be flanked by other clinical examinations

Human exome and mouse embryonic expression data implicate ZFHX3, TRPS1, and CHD7 in human esophageal atresia

2020

Introduction Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) occurs approximately 1 in 3.500 live births representing the most common malformation of the upper digestive tract. Only half a century ago, EA/TEF was fatal among affected newborns suggesting that the steady birth prevalence might in parts be due to mutational de novo events in genes involved in foregut development. Methods To identify mutational de novo events in EA/TEF patients, we surveyed the exome of 30 case-parent trios. Identified and confirmed de novo variants were prioritized using in silico prediction tools. To investigate the embryonic role of genes harboring prioritized de novo variants we perfor…

Curative endoscopic therapy in patients with early esophageal squamous-cell carcinoma or high-grade intraepithelial neoplasia.

2007

Background and study aims Endoscopic resection of esophageal squamous-cell neoplasia with curative intent is considered to be a safe and effective alternative treatment to radical surgery in cases where the neoplasia is intraepithelial or limited to the mucosal layer. These patients are at risk for recurrent malignancy in the preserved esophagus, however. We conducted a prospective study to evaluate the efficacy and safety of endoscopic resection and to analyze variables associated with recurrence in patients with mucosal or intraepithelial squamous-cell neoplasia. Patients and methods Between December 1997 and September 2005, 65 patients (mean age +/- standard deviation [SD] 62.9 +/- 9.5 y…

Koinzidenz von Plattenepithelkarzinomen der Speiseröhre und Kopf-Hals-Karzinomen: Risiko und Früherkennung

2007

Patients suffering from head and neck cancer (HNC) have or will develop a second esophageal squamous cell cancer (ESCC) in 5 - 14 %. When a second esophageal neoplasm occurs in a HNC patient, the prognosis is generally determined by the ESCC, and unfortunately it is poor. Prospective clinical studies in Japan, Brazil, Taiwan, France and Germany have shown that screening or surveillance using Lugol chromoesophagoscopy enables early detection of second esophageal neoplasias. Such a surveillance results in a survival benefit for HNC patients. Vice versa, ESCC patients also have a risk of 9.3 - 11.4 % for a head and neck cancer. Periodic otolaryngeal examination and pharyngoscopy is recommended…
