Background and Objectives: Colorectal cancer is the fourth leading cause of cancer death worldwide. Annually 1430000 cases would be diagnosed and half of these people would die of the disease. In Iran, colorectal cancer is the fifth common cancer among men and is the thirdamong women. This study was designed to estimate survival rates for patients with colorectal cancer and related factors. ...
evaluation of p53 codon 72 polymorphism in adenocarcinoma of the colon and rectum in guilan province
background : colorectal cancer is the second cause of mortality in developed countries. the p53gene and some of it's polymorphisms are among the causes for cancer development.the purpose of this study is to evaluate the relationship between the p53 codon 72 polymorphism in colorectal adenocarcinoma specimens compared with controls. materials and methods : we performed a case-control study among...
colorectal cancer is the most common gastrointestinal cancer and the second leading cause of cancer deaths worldwide. the purpose of this study is to investigate the prevalence of epstein-barr virus in patients with colorectal carcinomas and polyps in comparison with healthy people. in this analytical case-control study, 15 patients with colorectal cancer and 20 patients with colorectal polyp ...
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 colorectal cancer is classified in to three forms: sporadic (70-75%), familial (20-25%) and hereditary (5-10%). hereditary colorectal cancer syndromes classified into two different subtypes: polyposis and non polyposis. familial adenomatous polyposis (fap; omim #175100) is the most common polyposis syndrome, account for <1...
Introduction & Objective: One candidate gene for colorectal cancer susceptibility is exonuclease1 (EXO1) .It is a member of RAD2 nuclease family. It plays a main role in mismatch repair. EXO1 acts also in DNA replication and recombination. Single nucleotide polymorphisms (SNPs) are shown to be related with cancer incidence. The aim of the present study was to examine the association between P...
Colorectal cancer (CRC) is one of the most common types of cancers worldwide. Despite the improved therapeutic and diagnostic strategies and screening programs, morbidity and mortality of CRC is still considerable. Currently, most common approaches for diagnosis of CRC are colonoscopy and fecal occult blood test (FOBT). Because of the invasive nature of colonoscopy and low sensitivity of FOBT, ...
introduction: colo-rectal cancer has 10% prevalence, among all of the cancer proportionally and also it is the third common cancer in the both sexes. two recently introduced active drugs in the treatment of advanced colorectal cancer (acc) are irinotecan and oxaliplatin. the combinations of oxaliplatin (oxa) or irinotecan (iri) with 5fu-lv have been accepted as standard treatment for metastatic...
Abstract Background: Colorectal cancer is one of the most common cancers of gastrointestinal tract in Iran and the other parts of the world. Colorectal cancer is the fourth leading cause of cancer death in throughout the world. Almost every year recognizes one million new cases of colorectal cancer that nearly half a million of them die due to this disease. Materials and methods: In this ...
background: efficient screening for detection of colorectal cancer (crc) at earlier stages reduces its mortality. the purpose of this study was to investigate expression of carcinoembryonic antigen (cea) and human telomerase reverse transcriptase (htert) mrna in peripheral blood of crc patients and to present strategies for early detection screen test. methods: twenty seven patients in non-meta...
background kras and braf gene mutations are considered as key events in carcinogenesis progression of colorectal cancer. given the importance of these gene mutations evaluations, especially in metastatic patients, in terms of determination of therapeutic strategies, we studied the prevalence of kras and braf mutations in tabriz city. materials and methods deoxyribonucleic acid (dna) extracted...
