www.onk.ns.ac.rs/Archive Vol 20, No. 3-4, December 2012 PET IMAGING IN ESOPHAGEAL CARCINOMA Esophageal carcinoma is a relatively rare disease with approximately 13,200 new cases detected in 2001 in the United States (1). It is most common between 50 and 60 years of age with a male to female ratio of 4:1 (2). According to the SEER database, an annual age-adjusted incidence rate is 4.5 per 100,00...

PURPOSE Fascin, an actin bundling protein, induces membrane protrusions and increased cell motility in various transformed cells. The expression of fascin in epithelial neoplasms has been described only recently, and the role of fascin in esophageal squamous cell carcinoma (ESCC) is still unknown. EXPERIMENTAL DESIGN Paraffin sections of 200 patients with ESCC were immunohistochemically inves...

Secondary achalasia or pseudoachalasia is a rare esophageal motor abnormality, which mimics primary achalasia; it is not easily distinguishable from idiopathic achalasia by manometry, radiological examination, or endoscopy. Although the majority of reported pseudoachalasia cases are associated with neoplasms at or near the esophagogastric (EG) junction, other neoplastic processes or even chroni...

DNA damage response and repair are carried out by certain proteins following damage by environmental clastogens, such as ionizing radiation and reactive oxygen species. It has been reported that many carcinomas that are characterized by resistance to chemotherapy and poor outcomes show dysfunction of these proteins. Chromobox homologue 8 (CBX8), a member of the polycomb group of proteins, has b...

BACKGROUND Malignant melanoma in the gastrointestinal tract may be primary or metastatic. Mucosal melanoma is a quite rare and aggressive disease, growing hidden and diagnosed with a certain delay which makes treatment difficult. CASE REPORT The authors present the first patient with c-kit exon 11 mutated primary esophageal melanoma treated with oral tyrosine kinase inhibitor masitinib. A 55-...

Background & objective:Primary pleural neoplasms are rare entities compared with the pleural involvement by metastatic carcinoma. The current study aimed at investigating the complete spectrum of pleural neoplasms and differentiating between them with the aid of immunohistochemistry (IHC). Methods: Consecutive pleu...

  Introduction: Esophageal Squamous-Cell Carcinoma (SCC) is one of the most common malignancies in Iran. To reduce the incidence of esophageal SCC, it is important to recognize the controllable risk factors and prevent them. Celiac disease is widely known as a possible risk factor for esophageal SCC.  Thus, we decided to assess the frequency of celiac disease in esophageal SCC patients in North...

The carcinogenic effects of sequential treatment of female F344 rats with two nitrosamines were studied. The animals received either methylethylnitrosamine (NMEA), a strong liver carcinogen, N-nitrosomethylaniline (NMA), a moderately strong esophageal carcinogen, or N-nitrosopyrrolidine, (NPyr), a weaker liver carcinogen. The sequentially treated groups were given NMEA followed by NMA and vice ...

Esophageal malignancy encompasses a group of diseases that are mostly represented by the squamous cell carcinoma and the adenocarcinoma. Quite frequently, these neoplasms present aggressive behavior; therefore, the diagnosis is often made when the condition is in advanced stages. Dysphagia is the typical clinical complaint, although it is present only when most of the lumen is obstructed. There...
