چکیده

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 adenomatous polyps). we also estimated homeostasis model assessment insulin resistance index (homa-ir) in two groups. statistical analyses were performed using the student t-test and chi-square test. for all tests a p value ≤ 0.05 was considered to be statistically significant. results: the mean of waist circumference (p < 0.01), waist to hip ratio (p < 0.01), fasting serum glucose (p < 0.05), total cholesterol (p < 0.05), and ldl (p < 0.05) were significantly higher in patients with adenomatous polyps. the mean of hdl was significantly lower in patients with adenomatous polyps (p < 0.01). there was no relation between fasting serum insulin, igf-1 and glucose tolerance test with adenomatous polyps. hence homa-ir was higher in patients with adenomatous polyps (2.9 ± 2.6 vs. 2.82 ± 2.1), this difference was not significant statistically. conclusion: fasting hyperglycemia could be a risk factor to adenomatous polyps’ development. although this study did not show any relation between insulin resistance index and adenomatous polyps, further studies are needed for more evaluation.

Epidemiology of colorectal adenomatous polyps.

Colorectal cancer is currently the second leading cause of cancer death in the United States (1); nearly 7% of Americans are expected to develop this disease within their lifetime (2). Efforts to identify causes and effective preventive measures for this disease have led to the hypothesis that adenomatous polyps (adenomas), benign tumors that arise in the large bowel, are precursor lesions for ...

Interobserver Agreement in Assessing Dysplasia in Colorectal Adenomatous Polyps: A Multicentric Iranian Study

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...

The APC E1317Q variant in adenomatous polyps and colorectal cancers.

Genetic susceptibility may play a role in many colorectal cancers (CRCs). Known syndromes such as familial adenomatous polyposis and hereditary nonpolyposis CRC account for <5% of CRCs. The germ-line missense variant of the APC gene, E1317Q, has been proposed to confer a risk for colonic adenomatous polyps (adenomas), but not for CRCs in the general population. These findings are contradictory ...

Tobacco smoking and colorectal hyperplastic and adenomatous polyps.

Colorectal adenomas and possibly some hyperplastic polyps are precursors of colorectal cancer. Tobacco use is associated in epidemiologic studies with these polyps, although links between smoking and colorectal cancer are less consistent. To characterize the role of tobacco in early colorectal carcinogenesis, we compared tobacco use among 4,383 subjects with histologically verified benign (hype...

Analysis of mtDNA sequence variants in colorectal adenomatous polyps

Colorectal tumors mostly arise from sporadic adenomatous polyps. Polyps are defined as a mass of cells that protrudes into the lumen of the colon. Adenomatous polyps are benign neoplasms that, by definition display some characteristics of dysplasia. It has been shown that polyps were benign tumors which may undergo malignant transformation. Adenomatous polyps have been classified into three his...
