OBJECTIVES: To investigate fasting glucose, glucose tolerance, insulin resistance and insulin–like growth factor 1 in patients with or without colorectal polyps. MATERIALS AND METHODS: In this cross-sectional study, we evaluated fasting glucose, insulin, insulin–like growth factor 1 (IGF-1), lipid profile and glucose tolerance test in 103 patients undergoing colonoscopy (52 normal and 53 wit...
Background & Aims: Polyp is a protruding mass into the intestinal tract, which can be pedunculated or not. It is believed that most of colorectal cancers arise from adenomatous polyps. Materials & Methods: In this cross-sectional study pathology reports of 246 patients were evaluated. Results: In our study 64.2% of patients were male and 35.8% were female. The mean age of patients was 52.54±1...
Background & Objective: Most colorectal cancers (CRCs) arise from adenomatous polyps, and clinical management of this type of polyp is highly dependent on the reliability and validity of the pathological diagnosis. The aim of this study was to examine the interobserver agreement of five pathologists in assessing dysplasia in adenomatous polyps. Methods: I...
objectives: to investigate fasting glucose, glucose tolerance, insulin resistance and insulin–like growth factor 1 in patients with or without colorectal polyps. materials and methods: in this cross-sectional study, we evaluated fasting glucose, insulin, insulin–like growth factor 1 (igf-1), lipid profile and glucose tolerance test in 103 patients undergoing colonoscopy (52 normal and 53 with a...
Background & Aim: Colorectal polyps are among the commonest lesions encountered by surgical pathologist. In the United States, colonoscopy and flexible sigmoidoscopy are recommended for almost all people over the age of 40 years. The development of carcinoma from adenomatous lesions is referred to as the adenoma-carcinoma sequence. Virtually, all colorectal carcinomas exhibit genetic altera...
Background and purpose: Colorectal cancer is one of the most common types of cancers worldwide. Most of the times it is superimposed on an adenomatous polyp. Today, colonoscopy is the gold standard screening test for diagnosis of colorectal cancer which prevents developing cancer on the adenocarcinoma sequence path way. The goal of this study was to evaluate the gross and microscopic characteri...
Background and objective: Helicobacter pylori infection is one of the most common chronic bacterial infections in the world, especially in the developing countries. This bacterium is the cause of many diseases such as lymphoma, gastritis, peptic ulcers, and stomach cancer. According to recent reports, H. pylori infection can potentially increase the risk of colon cancer. The cu...
Microbiota is a collection of microorganisms that live in the oral cavity, respiratory tract and intestine of multicellular organisms. Microbiota exerts numerous physiological and pathological effects on the organism in which it resides. Increasing attention has been directed to the host-microbiota interaction, which is highly relevant to the development of carcinogenesis. Changes in the compos...
Background: Most of colorectal cancers arise from intestinal polyps. Evaluating of the expression level of genes that are involved in tumors growth and development, may consider as diagnostic factor of malignancy in the polyps. Failure of apoptosis is one of the causes of cancers. One of the key molecules in this pathway is Bid gene which connects the extrinsic to the intrinsic apoptosis pathwa...
AIM To investigate the relationship between non-alcoholic fatty liver disease (NAFLD) and colorectal adenomatous and hyperplastic polyps. METHODS A retrospective cross-sectional study was conducted on 3686 individuals undergoing health checkups (2430 males and 1256 females). All subjects underwent laboratory testing, abdominal ultrasonography, colonoscopy, and an interview to ascertain the ba...
