Cytokeratins are thought to play a role in apoptosis. Cytokeratin 18 (CK18) is involved in the formation of intracellular cytoskeleton, and has been considered a promising apoptosis marker in gastrointestinal carcinomas. Growth factors, including hepatocyte growth factor (HGF), may provide a microenvironment for malignant cells. In this study, we aimed to compare serum HGF and CK18 levels betwe...

background: in northeastern iran there is an area of high incidence of esophageal cancer which is populated by residents of turkmen ancestry. several environmental risk factors for esophageal cancer have been proposed, but the roles of familial and genetic factors have not been studied extensively in the turkmen population. materials and methods: we evaluated the importance of familial risk fac...

Esophageal carcinoma is among the most common cancers worldwide and a leading cause of cancer death [1]. Large numbers of studies indicated that chronic inflammation is closely associated with its development [21, 25]. Furthermore, the JAK/STAT pathway, which plays a critical role in inflammation and immunity, has been implied in a number of malignancies [11]. It has been shown that targeting t...

Purpose: Preferential expression of the g2 chain of laminin-5 in invading carcinoma cells has been implicated in tumor invasion. The aim of this study was to clarify the clinicopathological and prognostic significance of laminin g2 chain expression in esophageal squamous cell carcinoma (SCC). Experimental Design: We analyzed the association between immunohistochemically detected laminin g2 chai...

BACKGROUND The FAS receptor-ligand system is a key regulator of apoptotic cell death, and loss of FAS expression and gain of FAS ligand (FASL) expression play important roles in the development and progression of cancer. Single-nucleotide polymorphisms in the promoter region of the FAS (G or A at position -1377 [FAS -1377G/A] and A or G at position -670 [FAS -670A/G]) and FASL (T or C at positi...

The two main histological esophageal cancer types, adenocarcinoma and squamous cell carcinoma, differ in incidence, geographic distribution, ethnic pattern and etiology. This article focuses on epidemiology with particular reference to geographic and temporal variations in incidence, along with a review of the evidence supporting environmental and genetic factors involved in esophageal carcinog...

It has recently been suggested that angiotensin-I converting enzyme (ACE) inhibitors decrease the risk of cancer. However, studies to date have not investigated esophageal carcinoma. Therefore, we investigated the inhibitory effect of ACE inhibitors on growth of esophageal carcinoma xenografts. We used the EC9706 cell line, which expresses the highest vascular endothelial growth factor (VEGF) m...

Herein, a case of solitary, unilateral renal metastasis in a patient with curatively resected thoracic esophageal carcinoma, who achieved a pathological complete remission after neoadjuvant concurrent chemoradiotherapy, is reported. The kidney is the 4(th) or 5(th) most common visceral metastasis site of a primary esophageal carcinoma. More than 50% of renal metastases typically show bilateral ...

The author reviewed 950 cases of consecutive esophageal biopsies in the last 15 years in out pathology laboratory of our hospital. There were 223 malignant lesions (23.5%). The number and frequency (percentages) were as follows: 54 mild dysplasia (5.7%), 30 moderate dyplasia (3.2%), 32 severe dysplasia (3.4%), 13 carcinoma in situ (1.4%), 71 squamous cell carcinoma (7.5%), 7 primary adenocarcin...

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...
