Abstract: Background: Health care providers play an important role in planning & implementing policies to improve health behavior in the general population and increase participation in screening programs for early detection of cancer. This study was conducted to examine the effect of education on knowledge and the rate of participation of official administrative personnel with average risk fo...
Background: As the third leading cause of death, cancers have a special place in the Iranian health system. Several studies have been done in some regions of the country with few years of follow-ups, but this was the first standardized study to investigate the incidence trends of colorectal cancer in Iran in a one-decade period. Methods: The registered data for colorectal cancer cases...
Abstract Background : Cancer has not been elucidated in colerectal site. C-reactive protein (CRP) is a product synthesized in hepatocytes and has been reported to be up-regulated by such proinflammatory cytokines as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor (TNF). The significance of a preoperative serum elevation was evaluated using CRP as a predictive i...
Background: The molecular studies indicate some of the genes in the promoter region itself, will undergo methylation. Methylation of CpG islands in the promoter region of that cause silence or reduced expression of genes involved in cell growth pathways, which are colorectal cancer causing agents. Detection of methylation status can be used as a marker for cancer diagnosis and prediction of dis...
Introduction: Colorectal cancer is the third most common cancer in Iran. Some studies have shown that age and sex are associated with the course and prognosis of colorectal cancer. Due to the fact that recognizing the factors affecting colorectal cancer improves the screening system and selects better treatment modalities, and due to the lack of such studies in Iran, in this study, the relation...
Background and Purpose: Each year, about 50,000 new cases of cancer occur in Iran and the most common being the gastrointestinal (GI) tract (38%). Colorectal cancers account for the 3rd and 4th most prevalent cancers in Iranian men and women, respectively. Since genetic and environmental factors lead to differences in colorectal cancer occurrence in different geographic regions and races, we ...
Background: Colorectal cancer is the third most common type of aggressive cancers. Chemotherapy, surgery,and radiotherapy are the common therapeutic options for treating this cancer. Due to the adverse side-eff ects of these methods, immunotherapy is considered as an appropriate alternative therapeutic option. Treatment through the application of monoclonal antibodies is considered as a n...
Backgrounds: SIRT1 plays an important role in many physiological processes, including metabolism, neuronal protection, senecence and inflammatory, by staging histones and multiple transcription factors. However, the complex mechanisms of SIRT1 signaling in tumors are not yet fully understood, as it acts as both an oncogen and a tumor suppressor. On the other hand, it has been shown that the Lnc...
background: individuals with a positive family history of colorectal cancer have an increased risk of developing this type of cancer. the number of affected relatives and the age at diagnosis are two factors that increase the risk of colorectal cancer. the aim of this study was to assess the prevalence of a positive family history of colorectal cancer in a random sample among the iranian genera...
Background: Red Blood Cell's (RBC)’s folate may be related to decreased risk of colorectal adenoma. Methylenetetrahydrofolate reductase (MTHFR) is a key regulatory enzyme in folate metabolism. The MTHFR C677T polymorphism is located in the Exon 4 region and is associated with the change of folate level. This study evaluated the associations between RBC’s Folate levels and colorectal adenoma ris...
