conclusions expression of armc3 in tumor samples and normal adjacent tissue is very important. the expression of this gene in tumor-adjacent tissue may be associated with the stage of cancer; it may be that these tissues are affected by epigenetic and oncogenic changes of breast cancer. accordingly, aberrant expression of armc3 in tumor samples may be an attractive candidate for use as a tumor ...

introduction: as one of the most common cancers among head and neck malignancies, cancer of the oral cavity probably has some variations in countries with a high prevalence of esophageal cancer.  materials and methods: patients with oral cavity cancer who were treated at two tertiary referral centers from january 1999 to january 2009 were included in this study. in addition to demographic data,...

background: brca1 and brca2 genes have been recognized to be responsible for 20-30% of hereditary breast can­cers and approximately 50% of familial breast and ovarian cancers. therefore, the demand for brca1 and brca2 muta­tion screening is rapidly increasing as their identification will affect medical management of people at increased risk. because of high costs involved in analysis of brca1 a...

background: metastasis and recurrence of colorectal cancer after treatment is attributed to stem cells. the aim of this study was to determine the relationship between the expression of stem cell marker cd166 in colorectal cancer by immunohistochemistry and clinicopathologic parameters.methods: from 2006 to 2012, 121 colectomy specimens of patients with colon cancer that were operated in babol ...

background : cancer stem cells are a subgroup of tumor cells that have the capability for self-renewal and differentiation and are characterized by multiple markers. several studies have been conducted to identify these cells in colorectal cancer, including stem cell marker cd24. this study has evaluatedtheassociation of cd24 expression with clinicopathologic features and survival in an immunoh...

aim : the present study aimed to evaluate the prevalence of positive family history of these cancers in a large population-based sample of tehran province, capital of iran. background : upper gastrointestinal (ugi) cancers (gastric and esophagus cancer) constitute a major health problem worldwide. a family history of cancer can increase the risk for developing cancer and recognized as one of th...
