OBJECTIVE To investigate the reproducibility of diffusion-weighted magnetic resonance imaging (DW-MRI) in assessing tumor response early in the course of neoadjuvant chemoradiotherapy in patients with operable esophageal cancer. METHODS Eleven male patients (mean age 54.8 years) with newly diagnosed esophageal cancer underwent DW-MRI before and 10 days after start of chemoradiotherapy. Reprod...
Esophageal cancer is among the most deadly malignant diseases. However, the genetic factors contributing to its occurrence are poorly understood. Multiple studies with large clinic-based cohorts revealed that variations of the phospholipase C epsilon (PLCE1) gene were associated with esophageal cancer susceptibility. However, the causative role of PLCE1 in esophageal cancer is not clear. We ina...
Leiomyoma is one of the most commonly observed esophageal submucosal tumors, often appearing as a smooth-surfaced and semicircular protruded lesion. It sometimes grows toward the esophageal lumen and may be pedunculated in rare cases. We encountered a case of a pedunculated esophageal submucosal tumor diagnosed before treatment as a leiomyoma originating in the muscularis mucosae of a 68-year-o...
Esophageal carcinoid tumors remain some of the rarest of all carcinoid tumors, with only several cases previously reported in the literature. The endoscopic mucosal resection of selected carcinoid tumors has been shown to be a valid, safe, and effective method of treatment. Endoscopic ultrasonography is the technique of choice to select patients eligible for endoscopic resection. Here, we repor...
BACKGROUND Esophageal cancer in Iran is the sixth most common cancer and is particularly important in east Azerbaijan. The aim of this study was to calculate survival rates and define prognostic factors in esophageal cancer patients. METHODS In this study, all patients with esophageal cancer registered in the Radiation Therapy Center, during March 2006 to March 2011, were analyzed and followe...
Objective: To compare the result of preoperative computed tomography (CT) and postoperative pathological measurements of tumor length in cases of carcinoma esophagus. Material and Methods: Computed tomography thorax and upper abdomen with oral and intravenous contrast was done of biopsy proven 100 cases of carcinoma esophagus. The patients were then referred to Cardiothoracic Surgery Unit, PGMI...
AIM The present study aimed to investigate the influence of histological factors on survival of patients with esophageal cancer. BACKGROUND Esophageal cancer is almost the common form of malignancy in the eastern world. PATIENTS AND METHODS Through a retrospective cohort study a consecutive series of 134 patients with definite diagnosis of esophageal cancer who had been hospitalized at the ...
The purpose of this study was to determine the angiogenic profile of human esophageal carcinomas. The expression of vascular endothelial growth factor (VEGF) was examined in 6 esophageal carcinoma cell lines and 119 human esophageal carcinoma tissues by Northern blot analysis and immunohistochemistry, respectively. Immunohistochemistry using antibodies against CD34 (endothelial cell specific) w...
OBJECTIVE This study aims to explore the clinical characteristics of ABCE1 in esophageal cancers and its roles in the proliferation, invasiveness, migration and apoptosis of the esophageal carcinoma Eca109 cell line. METHODS The expression of ABCE1 and its target protein-RNase L, were first studied in tumor tissues of esophageal carcinoma and adjacent non-tumor tissues. The siRNA green fluore...
Esophageal cancer incidence is increasing and has few treatment options. In studying receptor tyrosine kinases associated with esophageal cancers, we have identified EPHB4 to be robustly overexpressed in cell lines and primary tumor tissues. In total, 94 squamous cell carcinoma, 82 adenocarcinoma, 25 dysplasia, 13 Barrett esophagus, and 25 adjacent or unrelated normal esophageal tissues were ev...
