Telomerase activation is one of the main pathways to immortalize cancer cells. In many kinds of cancer cells, this special reverse transcriptase stabilizes and elongates telomeres and prevents telomere erosion that naturally occurs in every cell division. Esophageal cancer is the fifth most frequent cause of cancer death worldwide, and is highly associated with alcohol, smoking, cultural ha...
Background: With approximately 386,000 deaths per year, esophageal cancer is the 6th most common cause of death due to cancer in the world. This cancer, like any other cancer, is the outcome of genetic alterations or environmental factors such as tobacco smoke and gastro-esophageal reflux. Tobacco smoking is a major etiologic factor for esophageal squamous cell carcinoma in western countries, a...
Abstract We show a robotic dissection with hook lymphadenectomy and ressection en bloc of distal esophageal tumor https://drive.google.com/file/d/1qnVnH3DTTv-uqnJRV3337sITqyZyX25K/view?usp=sharing.
total protein and dna extracted from histologically diagnosed normal nonmalignant and esophageal tumor tissues were used for analysis of polypeptides pattern by two-dimensional gel electrophoresis and dna transforming activity in nih 3t3 cell transfection assay, respectively. in comparison to normal tissues, eight polypeptides underwent down-regulation or disappeared, while seven polypeptides w...
BACKGROUND An attempt was made to improve metachronous oesophageal cancer prognosis through bi-annual systematic esophageal endoscopy screening in patients treated for head and neck cancer. PATIENTS AND METHODS Bi-annual esophageal endoscopy, without a staining procedure, was performed in 1560 patients from 1987 to 1997. The distribution of previous head and neck cancer was oral cavity (20%),...
Leiomyoma of the esophagus is rare, but it is the commonest among the benigh tumors of the esophagus. Among 95 cases of esophageal tumors, there was just 4 cases of Leiomyoma (3 were females and 1 was male) and this is contrary to the reports already published. Main symptoms of esophageal Leiomyoma include: Disphagia, pain and hematemesis from the above mentioned cases 1 tumor was in the thorac...
background: esophageal cancer is one of the prevalent cancers in east azerbaijan province. the aims of this study are to estimate the survival rate of patients with esophageal cancer by treatment modalities and tumor location, as well as risk factors such as cigarette smoking, family history, age at diagnosis, and gender. materials and methods: in a cross-sectional study we evaluated 142 patien...
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...
PURPOSE To establish effective antitumor immunotherapy for esophageal cancer, we tried to identify an useful target antigen of esophageal cancer. EXPERIMENTAL DESIGN We did cDNA microarray analysis to find a novel candidate antigen, proliferation potential-related protein (PP-RP). We examined cytotoxicity against tumor cells in vitro and in vivo of CTLs specific to PP-RP established from esop...
objective(s): cd44 is a member of the cell adhesion molecules family. naturally, cd44s, along with cd44v3 influence the cell motility, migration, and adhesion, while in tumor cells they lead to tumor invasion, progression, and metastasis. the purpose of this research is to evaluate the cd44s and cd44v3 expression in esophageal squamous cell carcinoma (escc) and to reveal their correlations wit...
