The methylenetetrahydrofolate reductase (MTHFR) gene is one of the most investigated of the genes associated with chronic human diseases because of its associations with hyperhomocysteinemia and toxicity. It has been proposed as a prototype gene for the prevention of colorectal cancer (CRC). The major objectives of this meta-analysis were to examine the polymorphism-mutation patterns of MTHFR and their associations with risk for CRC as well as potential contributing factors for mutations and disease risks. This analysis included 33,626 CRC cases and 48,688 controls across 92 studies for MTHFR 677 and 16,367 cases and 24,874 controls across 54 studies for MTHFR 1298, comprising data for various racial and ethnic groups, both genders, and multiple cancer sites...

BACKGROUND: Laparoscopic colectomy has been shown to have significant short- and long-term benefits compared to open approach. The incorporation of laparoscopy in developing countries is challenging, due to the high costs of equipment and lack of expertise. The aim of this study was to evaluate the safety and feasibility of laparoscopic colorectal surgery for cancer that could be performed in developing countries under different circumstances in developed countries. METHODS: Thirty-seven patients (23 males and 14 females) with colorectal cancer with a median age of 46 years (39-72) have been enrolled for laparoscopic colo-rectal surgery in a tertiary center in Egypt (South Egypt Cancer Institute) with the trend of reuse of some disposable laparoscopic instruments...

In Egypt colorectal carcinoma (CRC) is the most common type of malignancy of the digestive system. Selectively inhibiting neoangiogenesis by targeting tumor-associated blood vessels is an important therapeutic strategy. Prostate specific membrane antigen (PSMA) is expressed in the tumor-associated neovasculature of most solid cancers making it an interesting therapeutic target. We thought to study the expression of PSMA in a series of CRCs in order to test for its possible use as a target for antiangiogenic cancer therapy in Egyptian patients...

BACKGROUND: Epidermal growth factor receptor (EGFR) and its downstream factors KRAS and BRAF are mutated in several types of cancer, affecting the clinical response to EGFR inhibitors. Mutations in the EGFR kinase domain predict sensitivity to the tyrosine kinase inhibitors gefitinib and erlotinib in lung adenocarcinoma, while activating point mutations in KRAS and BRAF confer resistance to the anti-EGFR monoclonal antibody cetuximab in colorectal cancer. The development of new generation methods for systematic mutation screening of these genes will allow more appropriate therapeutic choices...

AIM: Prognosis of colorectal carcinoma depends on many factors, such as age and sex of patient; location; multiplicity; local extent and size of tumor, bowel obstruction, or perforation; as well as tumor microscopic type and grade; vascular and perineural invasion; and nodal and distant metastasis. The matrix metalloproteinases (MMPs) are a family of proteolytic enzymes strongly implicated in tumor invasion and metastasis, hence in tumor prognosis. The purpose of this study was to assess the role of MMP-2 and MMP-9 expression in colorectal tumorigenesis, invasion, and metastasis, hence their prognostic values...

Carcinoma of the large bowel is the fourth commonest cancer worldwide. The most frequent site for metastasis is the liver. Overall 30% of patients develop liver metastasis during the course of their illness; of these, 23% to 47% are synchronous lesions. These data are based on western studies. No data are published on patients with colorectal cancer from Egypt. We aimed to assess the incidence of colorectal liver metastasis in Egyptian patients and to evaluate the differences in the clinicopathological features and tumor behavior in patients with and without liver metastasis...

Mutations in the mitochondrial genome (mtDNA) are associated with different types of cancer, specifically colorectal cancer (CRC). However, few studies have been performed on precancerous lesions, such as ulcerative colitis (UC) lesions and adenomatous polyps (AP). The aim of this study was to identify mtDNA mutations in the cancerous and precancerous lesions of Egyptian patients. An analysis of the mutations found in six regions of the mtDNA genome (ND1, ND5, COI, tRNAser, D-loop 1, and 2) in 80 Egyptian patients (40 CRC, 20 UC, and 20 AP) was performed using polymerase chain reaction-single-strand conformational polymorphism techniques and followed up by direct sequencing...

BACKGROUND/AIMS: Colorectal cancer is one of the common cancers of the gastrointestinal tract in Egypt. It is characterized by a relatively earlier onset compared to that in the western world. Studying genetic alterations involved in colorectal cancer progression may help in identifying molecular biomarkers that can be used for early detection. METHODOLOGY: We analyzed DNA isolated from 83 cases including 38 colorectal carcinomas, 23 polyps (16 of which were adenomatous) and 22 cases with inflammatory bowel disease (IBD)...

OBJECTIVE: Colorectal cancer (CRC) is more common in developed countries and is the third most common cancer among both men and women. CRC provides an attractive model of tumour biology with normal mucosa to adenoma to carcinoma sequence. The TF-antigen (Thomsen-Friedenreich) can be identified by galactose oxidase-Schiff's (GOS) reaction either on tissues or on rectal mucus samples from patients with CRC. TF antigen is expressed in the neoplastic mucosa and not expressed in colonic mucosa of normal subjects...

BACKGROUND: In Egypt, few data are available on the outcome of colonoscopy. Epidemiologic studies have shown that inflammatory bowel disease (IBD) tends to increase. Endoscopists have reported an increasing incidence of IBD and colorectal cancer (CRC). This may be explained by an increasing index of suspicion and the availability of endoscopy. Population-based studies are lacking. AIM: The aim of our study was to retrospectively evaluate the patient characteristics and final diagnosis in patients subjected to colonoscopy in Tanta University Hospital and affiliated hospitals at the middle of Nile delta of Egypt, which is one of the most densely populated regions in the country...

PURPOSE: Lifestyle factors and environmental exposures might help explain the risk of colorectal carcinoma in countries where the incidence is low, but unique patterns of young onset and a high proportion of rectal cancer exist. METHODS: We obtained detailed lifestyle information from 421 patients with colorectal cancer and 439 hospital-controls in Egypt. Logistic regression models were computed to evaluate the risk factors of colorectal carcinoma. RESULTS: A history of pesticide exposure and more frequently eating food directly from farms were significantly associated with a higher risk of colorectal carcinoma (odds ratio = 2...

The study was planned as a pilot study to investigate two common polymorphisms in the MTHFR gene c.677C > T and c.1298A > C and their association with enhanced risk of colorectal cancer (CRC) in a sample of Egyptian individuals. Venous blood samples were withdrawn from 35 cases of CRC and 68 healthy controls. Specimens from colonic and rectal carcinoma tissues in addition to cancer free tissues were obtained from all cases. Frequencies of MTHFR677T and 1298C alleles were significantly higher among cases of CRC tumor tissues (50% and 56%, respectively) than germ line alleles in CRC patients (33% and 41%, respectively) and healthy controls (21% and 35%, respectively)...
