Esophageal cancer is the sixth leading cause of death from cancer and one of the least studied cancers worldwide. The global microRNA expression profile of esophageal cancer has not been reported previously. Here, for the first time, we have investigated expressed microRNAs in cryopreserved esophageal cancer tissues using advanced microRNA microarray techniques. Our microarray analyses identifi...

Background. Ultrasound (US) is the most accurate tool in the diagnosis of thyroid nodules if performed by expert physician. Misdiagnosis due to extrathyroidal lesions mimicking thyroid nodules is reported in literature. We describe the first case of an esophageal fibrovascular polyp misdiagnosed as a thyroid nodule on US examination. Patient Findings. A 54-year-old woman presented to emergency ...

OBJECTIVE To summarize the endoscopic screening findings in high-risk population of esophageal and gastric carcinoma and analyze influential factors related to screening. METHODS In seven selected cities and counties with high incidences of esophageal carcinoma, people at age of 40-69 were set as the target population. Those with gastroscopy contradictions were excluded, and all who were volu...

BACKGROUND Esophageal xanthoma is a very rare lesion which can be incidentally discovered during endoscopy. Only eleven cases have been reported, including ours. CASE REPORTS We present two new cases of esophageal xanthoma localized in the lower esophagus in a 56-year-old woman and a 62-year-old man. Endoscopically, esophageal xanthoma appears as yellowish granular spots or a slightly elevate...

BACKGROUND Esophageal cancer is one of the most serious tumor diseases worldwide, owing to its rapid development and fatal prognosis in most cases. To compare epidemiologic characteristics, data published by the International Agency for Research on Cancer, Lyon, France and data from Masaryk Memorial Cancer Institute, Brno, Czech Republic were used. METHODS We conducted a search of selected Cz...

As one of the most aggressive cancers, esophageal squamous cell carcinoma (ESCC) is the sixth leading cause of cancer deaths worldwide and particularly common in Asia. Over the decades, the clinical management of ESCC patients has barely advanced; and the overall survival remains poor, largely because its molecular basis, especially the genomic abnormalities, is obscure, and no targeted therapy...

Esophageal melanosis which is characterized by melanocytic proliferation in the squamous epithelium of the esophagus and melanin accumulatin of esophageal mucosa (EM) is a rare disease of the digestive system. Although esophageal melanosis is considered to be a benign disease, its etiology is not cleared and has been reported to be the precursor lesion of esophageal primary melanomas. In this r...

Gastroesophageal reflux disorder (GERD), a common disorder in the Western world, can lead to complications that include esophageal stricture and esophageal adenocarcinoma. Multiple challenges are associated with GERD treatment. First, lack of symptoms does not correlate with the absence of or the healing of esophageal lesions. Second, proton pump inhibitors, the current standard of care for GER...

The patient was a 76-year-old woman who had noticed slight difficulty in swallowing in the 3 years prior to this presentation. Her dysphagia progressed while she was hospitalized following cervical cancer surgery. Esophagogastroduodenoscopy and an esophagram showed circumferential erosion and a stricture of the thoracic esophagus. Esophageal resection was performed; the resected specimens showe...
