AIM Orthotopic models utilizing orthotopic implantation have been used for developing cancer models of multiple tumor entities. The aim of this study was to evaluate the role of orthotopic injection in establishing a model of esophageal cancer using a human green fluorescent protein (GFP) cell line of human esophageal carcinoma. MATERIALS AND METHODS Nude mice were orthotopically injected in ...

Introduction: Early diagnosis and appropriate treatment is required in esophageal cancer due to its invasive nature. The aim of this study was to evaluate early post-esophagectomy complications in patients with esophageal cancer who received neoadjuvant chemoradiotherapy (NACR).   Materials and Methods: This randomized clinical trial was carried out between 2009 and 2011. Patients with lower-th...

In Japan and China, esophageal cancer is common and more than 90% of esophageal cancers are squamous cell carcinoma. Esophageal squamous cell carcinoma (ESCC) shows a poor prognosis, but the mechanism of ESCC and target genes for treatment remains unclear. We searched for genes related to ESCC, and identified a novel gene, FLJ11021, which was designated arginine/serine-rich coiled-coil 2 (RSRC2...

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 habits...

Esophageal cancer incidence rates have been increasing over the past years and survival remain low. According to Global Cancer Observatory, 3.1% of new cases consists esophageal 5.5% deaths was due cancer. Histologic classification comprises either squamous cell carcinoma (SCC) or Adenocarcinoma. Other types are reported be uncommon. We present a case 33-year old male admitted progressive dysph...

Resistance to chemotherapeutic agents is the main reason for treatment failure in patients with cancer. The primary mechanism of multidrug resistance (MDR) is the overexpression of drug efflux transporters, including ATP‑binding cassette transporter G2 (ABCG2). To the best of our knowledge, the MDR mechanisms of esophageal cancer have not been described. An adriamycin (ADM)-resistant subline, Ec...

esophageal cancer is one of the most common malignancies in our country. patients often seek medical advice in advanced and inoperable stages or with cervical esophageal cancer, in which operation is accompanied by sever morbidity. in this conditions many of them cannot tolerate chemo-radiation, or refuse it. therefore radiotherapy is applied as a single modality in palliation of many patients ...
