The pathogenesis of eosinophilic esophagitis (EoE) is incompletely understood. In certain eosinophilic diseases, activation of tyrosine kinase after fusion of the Fip1-like-1 and platelet-derived growth factor receptor-α genes (F-P fusion gene) mediates eosinophilia via downstream effectors such as
This phase I trial investigates the safety of combining radiation, 5-fluorouracil (5-FU) and cisplatin with the epidermal growth factor receptor tyrosine kinase inhibitor, erlotinib, in patients with esophageal carcinoma. From April 2000 to January 2005, 11 patients with squamous or adenocarcinoma
Esophagitis after total gastrectomy has been associated with biliary and pancreatic reflux into the esophagus. The purpose of this study is to clarify the effect of FOY-305 on these factors in the esophagitis. We initially produced esophagitis in rats with total gastrectomy followed by an
OBJECTIVE
Eosinophilic esophagitis (EoE) is a chronic allergic disease triggered by food allergens with an increasing prevalence. This review highlights recent research advances in EoE with a focus on the literature of the past 18 months.
RESULTS
The incidence of EoE in the black population is
Previous case reports have described esophagitis thought to be secondary to crizotinib, an oral tyrosine-kinase inhibitor used in the treatment of anaplastic lymphoma kinase- (ALK-) positive non-small cell lung cancer (NSCLC). In those reports, the interval development of esophagitis was between two
Crizotinib is an oral tyrosine kinase inhibitor, approved by the FDA in 2011, for use in anaplastic lymphoma kinase positive, metastatic, non-small cell lung cancer. Crizotinib inhibits oncogenic protein expression and impairs cellular proliferation in tumors with an overexpressed anaplastic
OBJECTIVE
To establish the safety profile and efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) concurrent with individualized radiotherapy (RT) in patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC).
METHODS
Between June 2007 and January
Crizotinib is an oral tyrosine-kinase inhibitor that inhibits anaplastic lymphoma kinase (ALK) in gene-rearranged non-small cell lung cancer (NSCLC). In 2011, the Food and Drug Administration approved crizotinib for treatment of locally advanced or metastatic ALK-positive NSCLC. The crizotinib
Although interleukin (IL)-13 and neurotrophins are functionally important for the pathogenesis of immune responses, the interaction of these pathways has not been explored. Herein, by interrogating IL-13-induced responses in human epithelial cells we show that neurotrophic tyrosine kinase receptor,
Esophageal adenocarcinoma (EAC) is the eighth most common cancer worldwide, and approximately 15% of patients survive 5years. Reflux disease (GERD) and Barrett's esophagus (BE) are major risk factors for the development of EAC, and epidemiologic studies highlight a strong association with obesity.
OBJECTIVE
Experimental studies suggest that free radicals are involved in acid and pepsin-induced damage of esophageal mucosa. The profile and balance between free radicals and antioxidant systems in human esophagitis are unknown.
METHODS
Superoxide anion and its powerful oxidant reaction with
Many pediatric diseases demonstrate blood or tissue eosinophilia. Included among these disorders are common atopic diatheses such as asthma as well as the rarer conditions of hypereosinophilic syndrome and eosinophilic gastrointestinal disorders. Eosinophil trafficking and activation in target
The incidence of eosinophilic esophagitis (EoE) is greater in male than female subjects, and the underlying molecular basis for this sex bias remains unclear.We sought to delineate the contribution of the sex hormone estrogen to the EoE phenotype and Reflux esophagitis results from repeated exposure of the esophagus to acidic gastric juice or bile-containing duodenal contents. In Barrett's adenocarcinoma, acid increases proliferation via ERK and p38 MAPK activation. This study was focused on determination of the mechanism(s) underlying MAPKs
Concurrent chemoradiotherapy is the standard treatment for patients with locally advanced esophageal squamous cell carcinoma. However, a number of patients present intolerance to chemoradiotherapy because of advanced age or malnutrition. Erlotinib, an inhibitor of epidermal growth factor receptor
