AIM To investigate the putative role of human papillomavirus (HPV) infection in the carcinogenesis of esophageal squamous cell carcinoma in China. METHODS Twenty-three esophageal squamous cell carcinoma samples and the distal normal epithelium from Shanxi Province, and 25 more esophageal squamous cell carcinoma samples from Anyang city, two areas with a high incidence of esophageal cancer in ...
Particularly interesting new cysteine-histidine rich protein (PINCH), as a newly discovered protein of LIM family members, may play a role in signal transduction of integrin and growth factor, and involved in the incidence and development of tumors. PINCH protein is overexpressed in tumor-associated stroma of several types of tumors. However, there is no study of the PINCH in esophageal cancer,...
HEADINGS Esophageal neoplasms. Neoplasms, squamous cell. Adenocarcinoma. Esophagectomy. ABSTRACT Background Medical literature has recorded a significant and progressive increase in the prevalence of esophageal adenocarcinoma in recent years, and this fact has epidemiological importance in the treatment, in the evolution and prognosis of patients. Aim A retrospective study of esophageal tumors ...
Cyclo-oxygenase (COX)-2 is not usually detectable in normal tissues but is induced in inflammation and carcinogenesis. The level of COX-2 is elevated in cancer tissues of the colon, bladder, and skin. In the esophagus, squamous cell carcinoma and adenocarcinoma are known to express COX-2. The purpose of this study was to clarify the association of COX-2 expression with clinicopathological facto...
Introduction: Despite the high incidence of esophageal and thymic carcinoma in human being, co-existence of these two malignant lesions is very rare. In this study we have reported an 81 year old man with a huge mediastinal tumor (Thymoma) and Squamous Cell Carcinoma (SCC) of esophagus. Case report: An 81 year old man presented with hiccups and progressive dysphagia for solids and was admit...
A case of esophageal carcinoma exclusively composed of adenocarcinoma simulating an esophageal gland duct in a 61-year-old man is presented. The tumor arose as a slightly elevated lesion in the middle intrathoracic esophagus. It was almost completely overlaid with non-neoplastic stratified squamous epithelial cells. Beneath the overlying surface epithelium, an adenocarcinoma that was bilayered ...
stenosis, more than 10 cm of the esophagogastric junction. The biopsy diagnosed esophageal squamous carcinoma and gastric adenocarcinoma. CT of chest, abdomen and pelvis dismissed pleural effusion or chest lymphnodes. Showed concentric thickening of the lower third of the esophagus, in gastroesophageal junction, antrum and lymph node along the lesser gastric curvature . Liver was normal in size...
Esophageal cancer (EC) occurs commonly, particularly in Asia, and it is the sixth leading cause of cancer deaths worldwide [1]. Esophageal cancer classically happens in one of two forms, squamous cell carcinomas (SCCs) arising from the stratified squamous epithelial lining of the organ, and adenocarcinoma (AC) arising from columnar glandular cells that replace the squamous epithelium [2]. Sarco...
BACKGROUND The Wilms' tumor gene WT1 is overexpressed in various kinds of solid cancers. However, it remains unclear whether WT1 is expressed in esophageal squamous cell carcinoma. MATERIALS AND METHODS Expression of the WT1 gene was examined by real-time RT-PCR in 12 esophageal squamous cell carcinoma (ESCC) and by immunohistochemistry in 9 of these 12 and another 29. RESULTS Real-time RT-...
Background: Esophageal Squamous Cell Carcinoma (ESCC) is the seventh most common and lethal malignancy worldwide with a high incidence in Iran. Esophageal cancer has a poor prognosis and low 5-years survival rate. Despite several studies on esophageal cancer, its underlying mechanism remains unclear. Therefore, it is significant to analyze the molecular factors involved in disease for introduci...
