Background: Knowing esophageal tumors behavior in relationship to lymph node involvement, distant metastases and local tumor invasion is of paramount importance for the best esophageal tumors management. Aim: To describe lymph node involvement, distant metastases, and local tumor invasion in esophageal carcinoma, according to tumor topography and histology. Methods: A total of 444 patien...
The study was conducted to determine the manifestation of esophageal carcinoma in Iranian patients. 92 cases with esophageal carcinoma that hospitalized in Rasool - E Akram and Rahnamoon General Hospitals were studied retrospectively. 57% of the patients were males and 62% in 50 - 70 years old ages. The common symptoms were: dysphagia (96%), odynophagia (69%) , restrosternal pain (59%) , regurg...
INTRODUCTION Esophageal cancer portends a grim prognosis. Most patients present with incurable disease. Scanty epidemiologic data on the disease has contributed to its low priority on the national. We sought to evaluate the current national trend in the presentation and outcome of esophageal cancer using our institutional experience from 1992 - 2010. METHODS This is a retrospective study base...
A case of collision carcinoma (squamous cell carcinoma and Barrett's adenocarcinoma) in the residual cervical esophagus of a 68-year-old woman at 27 years after subtotal esophagectomy for thoracic esophageal carcinoma is reported. The patient initially noticed cervical dysphagia in 2002, but did not seek treatment. In April 2004, the patient was referred to our department by a local physician w...
“The preoperative staging of esophageal carcinoma is critically important for selecting the most appropriate treatment,” study author Ichiro Yamada, MD, of the department of diagnostic radiology and oncology at Tokyo Medical and Dental University told Diagnostic Imaging. However, according to background information in the study, current imaging modalities including computed tomography, ultrason...
BACKGROUND Worldwide, esophageal carcinoma is one of the most aggressive cancers. It is relatively common in many countries and characterized by poor prognosis and rapid clinical progression. PURPOSE In this study, we aimed to evaluate the role of CD34, the marker of vascular endothelial cells, MMP-9 (matrix metalloproteinase type 9) and p53 in esophageal carcinoma. MATERIALS AND METHODS Fo...
The risk of the future development of primary esophageal cancer after endoscopic esophageal mucosal resection of esophageal cancer is not known; hence, there are no established guidelines for follow-up surveillance programs. Simultaneous occurrence of multiple cancers associated with esophageal cancer is common among heavy drinkers who have the inactive form of aldehyde dehydrogenase-2 (ALDH2) ...
In the present study, we examined the expression of peroxisome proliferator-activated receptor gamma (PPARgamma) and the growth-inhibitory effects of Troglitazone and Pioglitazone, selective ligands for PPARgamma, using a series of human esophageal carcinoma cell lines (TE-1, -3, -7, -8, -12 and -13). PPARgamma expression was detected in all six human esophageal carcinoma cell lines. The esopha...
BACKGROUND A malignant tracheoesophageal/bronchoesophageal fistula (TEF) is a life-threatening complication of esophageal squamous cell carcinoma. A feeding gastrostomy/jejunostomy had been the most common treatment method for patients with TEF before the era of stenting. The aim of this retrospective study is to compare the prognosis of esophageal squamous cell carcinoma patients with TEF trea...
The genetic alterations that occur during esophageal tumorigenesis have yet to be determined. We previously established a Wister rat carcinogenesis model of esophageal squamous cell carcinoma. To understand more about the molecular mechanisms during carcinogenesis, we produced esophageal neoplastic lesions by administering N-amyl-N-methylnitrosamine and 12-O-tetradecanoylphorbol-13-acetate to r...
