Evaluation of the sensitivity and specificity of sigmoidoscopy in comparison to colonoscopy regarding the detection of intestinal inflammatory activity in the follow-up of patients with ulcerative colitis. GASTROENTEROLOGIA Y HEPATOLOGIA 2024:502232. [PMID: 39029790 DOI: 10.1016/j.gastrohep.2024.502232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2024] [Revised: 07/04/2024] [Accepted: 07/07/2024] [Indexed: 07/21/2024]
Abstract
INTRODUCTION Ulcerative colitis (UC) is a chronic disease characterized by periods of inflammatory activity and remission, which vary from the rectum to the proximal colon. Currently, mucosal healing is a long-term goal in the management of inflammatory bowel disease, with colonoscopy and sigmoidoscopy being the recommended tools for evaluation. OBJECTIVE To assess the effectiveness of both examinations in determining the presence of inflammatory activity in the follow-up of patients with UC. METHODS Retrospective observational study analyzing colonoscopies performed as part of the follow-up of UC patients between January 2021 and July 2023 by gastroenterologists from the Inflammatory Bowel Disease Program at the Clínica Universidad de los Andes. The study compared endoscopic and histological activity observed in the rectosigmoid region with that found in the rest of the colon. Sensitivity and specificity were determined using concordance and correlations tests. RESULTS A very good concordance and correlation were observed regarding endoscopic findings, with a Kappa index of 0.97 and a Spearman coefficient of 0.97. The Positive Predictive Value (PPV) of sigmoidoscopy for endoscopic activity was 1, and the Negative Predictive Value (NPV) was 0.96. In relation to histological activity, the concordance had a Kappa index of 0.93 and a Spearman coefficient of 0.93, with a PPV of sigmoidoscopy for histological activity being 1 and an NPV of 0.91. CONCLUSION This cohort suggests that sigmoidoscopy is a cost-effective option for evaluating mucosal healing in UC patients in symptomatic and biomarker remission. However, complete colonoscopy should be considered in cases of discrepancies with the clinical picture or in colorectal cancer surveillance.

Abstract
This paper is an update of the diagnostic and therapeutic recommendations of the National Consultant for Gastroenterology and the Polish Society of Gastroenterology from 2013. It contains 49 recommendations for the diagnosis and treatment, both pharmacological and surgical, of ulcerative colitis in adults. The guidelines were developed by a group of experts appointed by the Polish Society of Gastroenterology and the National Consultant in the field of Gastroenterology. The methodology related to the GRADE methodology was used to assess the quality of available evidence and the strength of therapeutic recommendations. The degree of expert support for the proposed statements was assessed on a 6-point Likert scale. Voting results, together with comments, are included with each statement.

Abstract
Simple Summary Colorectal cancer (CRC) is one of the most serious potential complications of inflammatory bowel diseases (IBDs). The aging of patients affected by IBDs makes this issue a challenge that will increasingly be faced by clinicians in clinical practice, especially in light of the poorer prognosis for CRC in this group of people when compared with the general population. In this review, we summarize the current epidemiology, risk factors and various prevention strategies proposed for CRC in patients with IBDs. Abstract Colorectal cancer (CRC) is currently the third most frequent form of malignancy and the second in terms of mortality. Inflammatory bowel diseases (IBDs) are recognized risk factors for this type of cancer. Despite a worldwide increase in the incidence of CRC, the risk of CRC-related death in IBD patients has declined over time, probably because of successful surveillance strategies, the use of more effective drugs in the management of remission and improved indications to colectomy. This notwithstanding, CRC 5-year survival in patients with IBD is poorer than in the general population. This review provides a summary of the epidemiological features, risk factors and various prevention strategies proposed for CRC in IBD patients. Moreover, there is a special focus on reporting and highlighting the various prevention strategies proposed by the most important international scientific societies, both in terms of chemoprevention and endoscopic surveillance. Indeed, in conducting the analysis, we have given attention to the current primary, secondary and tertiary prevention guidelines, attempting to emphasize unresolved research and clinical problems related to this topic in order to improve diagnostic strategies and management.

[PMID: 36059706 PMCID: PMC9428707 DOI: 10.3389/fonc.2022.912882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 07/18/2022] [Indexed: 12/09/2022] Open
Abstract
Background Early diagnosis of colorectal cancer could significantly improve the prognosis and reduce mortality. However, indeterminate diagnosis is often met in pathology diagnosis in biopsy samples. Abnormal expression of long non-coding RNA (lncRNA) is associated with the initiation and progression of colorectal cancer. It is of great value and clinical significance to explore lncRNAs as candidate diagnostic biomarkers in colorectal cancer. Methods Based on the within-sample relative expression levels of lncRNA pairs, we identified a group of candidate diagnostic biomarkers for colorectal cancer. In addition, we validated it in independent datasets produced by different laboratories and different platforms. We also tested it in colorectal cancer tissue samples using quantitative real-time polymerase chain reaction (RT-qPCR). Results A biomarker consisting of six lncRNA pairs including nine lncRNAs was identified for the diagnosis of colorectal cancer. For a total of 950 cancer samples and 247 non-cancer samples, both of the sensitivity and specificity could achieve approximately 90%. For adenoma samples, the accuracy could achieve 73%. For normal tissues from inflammatory bowel disease patients, 93% (14/15) were correctly classified as non-cancer. Furthermore, the lncRNA pair biomarker showed excellent performance in all clinical stages; even in the early stage, the accuracy could achieve 87% and 82% in stage I and II. Meanwhile, the biomarker was also robust to the microsatellite instability status. More importantly, we measured the biomarker in 35 colorectal cancer and 30 cancer-adjacent tissue samples using quantitative real-time polymerase chain reaction (RT-qPCR). The accuracy could achieve 93.3% (70/75). Specially, even in early-stage tumors (I and II), the accuracy could also achieve 90.9% (30/33). The enrichment analysis revealed that these lncRNAs were involved in highly associated cancer pathways and immune-related pathways. Immune analysis showed that these marker lncRNAs were associated with multiple immune cells, implying that they might be involved in the regulation of immune cell functions in colorectal cancer. Most of the biomarker lncRNAs were also differentially expressed between the mutant group and wild-type group of colorectal cancer driver genes. Conclusion We identified and validated six lncRNA pairs including nine lncRNAs as a biomarker for assisting in the diagnosis of colorectal cancer.
