Heterogeneity in colorectal cancer incidence among people recommended 3-yearly surveillance post-polypectomy: a validation study

Conclusion As previously demonstrated for hospital patients, screening participants classified as intermediate risk comprised two risk subgroups. Surveillance clearly benefited the higher-risk subgroup. [...] © Georg Thieme Verlag KG Stuttgart · New YorkArticle in Thieme eJournals: Table of contents  |  Abstract  |  open access Full text

In this study, we examined whether HASPIN inhibitor CHR-6494 suppresses cancer progression in ApcMin/+ mice, a familial colon tumor disease model. Mice were treated by intraperitoneal injection of CHR-6494 for 50 days. Following the treatment period, intestinal polyps were counted and testosterone and spermatogenesis levels were observed. Intraperitoneal administration of CHR-6494 significantly inhibited intestinal polyp development and recovered body weight in ApcMin/+ mice. Although spermatogenesis was inhibited with increasing age in ApcMin/+ mice, CHR-6494 significantly improved blood testosterone levels and spermatoge...

CONCLUSIONS: Calcium alone or in combination with vitamin D may reduce the risk of SCC, but not BCC. This trial was registered at clinicaltrials.gov as NCT00153816. PMID: 33022713 [PubMed - as supplied by publisher]

Fluorescence molecular endoscopy (FME) is an emerging technique that has the potential to improve the 22% colorectal polyp detection miss-rate. We determined the optimal dose-to-imaging interval and safety of FME using EMI-137, a c-Met–targeted fluorescent peptide, in a population at high risk for colorectal cancer. Methods: We performed in vivo FME and quantification of fluorescence by multidiameter single-fiber reflectance/single-fiber fluorescence spectroscopy in 15 patients with a dysplastic colorectal adenoma. EMI-137 was intravenously administered (0.13 mg/kg) at a 1-, 2- or 3-h dose-to-imaging interval (n = 3 ...

Colonoscopy is the most commonly performed endoscopic examination worldwide and is considered the gold standard for colorectal cancer screening.The quality of examination and endoscopic treatment is affected by a number of factors that are verified by recognized parameters, such as cecal intubation rate and time, withdrawal time, adenoma detection rate and polyp detection rate.The aim of the study was to assess the suitability of 330-degree panoramic colonoscopy for the detection of colorectal lesions and to analyze the functionality of a special endoscope series in regard to cecal intubation rate, cecal intubation time, and withdrawal time.

CONCLUSION: This study provides additional evidence of the association between low fruit and vegetable consumption and colorectal polyps. Enhancing people fiber eating behavior may help preventing colorectal cancer risk. PMID: 32986375 [PubMed - as supplied by publisher]

Conclusions: Adenomatous polyps are very important in childhood because of rarity. In particular, the presence of cafe au lait spots and a history of malignancy detected in relatives at an early age must be considered for CMMRD.

bel Trias José Ignacio Busteros Gemma Mateu Francesc Balaguer María-Teresa Fernández-Figueras Manel Esteller Eva Musulén The use of epithelial cell adhesion molecule (EPCAM) immunohistochemistry (IHC) is not included in the colorectal cancer (CRC) screening algorithm to detect Lynch syndrome (LS) patients. The aim of the present study was to demonstrate that EPCAM IHC is a useful tool to guide the LS germ-line analysis when a loss of MSH2 expression was present. We retrospectively studied MSH2 and EPCAM IHC in a large series of 190 lesions composed of malignant neoplasms (102), p...

AbstractPurposeIGF-1Ec is an isoform of Insulin-like growth factor 1 (IGF-1) and has recently been identified to be overexpressed in cancers including prostate and neuroendocrine tumours. The aim of this paper is to investigate the expression of IGF-1Ec in colorectal cancer and polyps compared to normal colon tissues and its association with recurrent disease using semi-quantitative immunohistochemistry.MethodsImmunohistochemistry for IGF-1Ec expression was performed for colorectal cancer, colorectal polyps and normal colonic tissues. The quantification of IGF-1Ec expression was performed with the use of Image J software a...

A 64-year-old man presented with large colon polyp detected by screening colonoscopy. The colonoscopy showed a 20-mm pedunculated polyp with a thick and bulging stalk in the sigmoid colon (Figure A). Endoscopic ultrasonography revealed that the stalk consisted of a low echoic structure in the submucosa, considering of a cystic component (Figure B, arrows). Although the polyp was suspected of an invasive cancer, biopsies from the polyp head revealed tubular adenoma. Endoscopic resection was performed for pathological diagnosis and local treatment at the patient ’s request.
