background: some recent studies reported human epidermal growth factor receptor (her-2/neu) as a marker that can be used in immunological studies of colorectal carcinoma for predicting the prognosis and the treatment. therefore, we aimed to investigate the frequency of her-2 expression in patients with colorectal cancer, and explore the relationship between clinicopathological prognostic factor...

Frizzled homolog 3 receptor was up-regulated in several gastrointestinal cancers such as esophageal and gastric cancers. Moreover, frizzled homolog 3 has recently reported to be expressed in colorectal adenoma specimens. In the present study, we investigated the clinical significance of frizzled homolog 3 protein in colorectal cancer patients. Using immunocytochemical staining, frizzled homolog...

intraocular metastatic tumors have been increasingly reported in the recent past. unlike choroidal metastasis, metastasis to retina is very rare and so far has been reported in very few case reports only. case presentation : a 56 year-old male who presented with a history of adenocarcinoma of the cecum and underwent lap colectomy for the primary cecal tumor, received adjuvant chemotherapy for a...

background: â  colorectal cancer (crc) is one of the most common invasive cancers responsible for physical and psychosocial morbidity. therefore, quality of life (qol) is an important outcome for these patients. despite advances in understanding qol, the majority of available research is from urban areas. the present study aims to compare qol between urban and rural crc patients. â  materials a...

mono-targeting by imatinib as a main antitumor agent does not always accomplish complete cancer suppression. 2,5-dimethyl-celecoxib (dmc) is a close structural analog of the selective cyclooxygenase-2 (cox-2) inhibitor, celecoxib, that lacks cox-2 inhibitory function. in this study, we aimed to show the apoptotic effects of imatinib in combination with dmc in human ht-29 colorectal cancer (crc)...

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...

PURPOSE Focal adhesion kinase (FAK), a protein tyrosine kinase that functions in signaling events between cells and their extracellular matrix, is overexpressed in a variety of human solid tumors. To determine whether FAK expression is up-regulated in colorectal cancer, we analyzed FAK mRNA and protein levels in primary colorectal tumors and colorectal liver metastases. EXPERIMENTAL DESIGN p1...

This study investigated the roles of Notch‑1 in colorectal carcinoma, to assess the mechanisms. The expression of Notch‑1 and its ligand-Jagged1 was detected in human colorectal carcinoma, colorectal adenoma, paracancerous tissue and normal colorectal tissue by immunohistochemistry. Colorectal carcinoma cell lines were utilized to confirm the expression of Notch‑1 in colorectal carcinoma cells....

Synchronous colorectal carcinoma refers to more than one primary colorectal carcinoma detected in a single patient at initial presentation. A literature review has shown that the prevalence of the disease is approximately 3.5% of all colorectal carcinomas. This disease has a male to female ratio of 1.8:1. The mean age at presentation of patients with synchronous colorectal cancer is in the earl...

it is clear that colorectal cancer (crc) develops through multiple genetic and epigenetic pathways. these pathways may be determined on the basis of three molecular features: (i) mutations in dna mismatch repair genes, leading to a dna microsatellite instability (msi) phenotype, (ii) mutations in apc and other genes that activate wnt pathway, characterized by chromosomal instability (cin) pheno...
