Abstract
PURPOSE The diagnostic accuracy of Narrow Band Imaging (NBI) in the endoscopic surveillance of ulcerative colitis (UC) has been disappointing in most trials which used the Kudo classification. We aim to compare the performance of NBI in the lesion characterization of UC, when applied according to three different classifications (NICE, Kudo, Kudo-IBD). METHODS In a prospective, real-life study, all visible lesions found during consecutive surveillance colonoscopies with NBI (Exera-II CV-180) for UC were classified as suspected or non-suspected for neoplasia according to the NICE, Kudo and Kudo-IBD criteria. The sensitivity (SE), specificity (SP), positive (+LR) and negative (-LR) likelihood ratios of the three classifications were calculated, using histology as the reference standard. RESULTS 394 lesions (mean size 6 mm, range 2-40 mm) from 84 patients were analysed. Twenty-one neoplastic (5%), 49 hyperplastic (12%), and 324 inflammatory (82%) lesions were found. The diagnostic accuracy of the NICE, Kudo and Kudo-IBD classifications were, respectively: SE 76%-71%-86%; SP 55-69%-79% (p < 0.05 Kudo-IBD vs. both Kudo and NICE); +LR 1.69-2.34-4.15 (p < 0.05 Kudo-IBD vs. both Kudo and NICE); -LR 0.43-0.41-0.18. CONCLUSION The diagnostic accuracy of NBI in the differentiation of neoplastic and non-neoplastic lesions in UC is low if used with conventional classifications of the general population, but it is significantly better with the modified Kudo classification specific for UC.

Abstract
INTRODUCTION Patients with ulcerative colitis (UC) develop not only UC-associated neoplasias but also sporadic neoplasias (SNs). However, few studies have described the characteristics of SNs in patients with UC. Therefore, this study aimed to evaluate the clinical features and prognosis of SNs in patients with UC. METHODS A total of 141 SNs in 59 patients with UC, detected by surveillance colonoscopy at Hiroshima University Hospital between January 1999 and December 2021, were included. SNs were diagnosed based on their location, endoscopic features, and histopathologic findings along with immunohistochemical staining for Ki67 and p53. RESULTS Of the SNs, 91.5% were diagnosed as adenoma and 8.5% were diagnosed as carcinoma (Tis carcinoma, 3.5%; T1 carcinoma, 5.0%). 61.0% of the SNs were located in the right colon, 31.2% were located in the left colon, and 7.8% were located in the rectum. When classified based on the site of the lesion, 70.9% of SNs occurred outside and 29.1% within the affected area. Of all SNs included, 95.7% were endoscopically resected and 4.3% were surgically resected. Among the 59 patients included, synchronous SNs occurred in 23.7% and metachronous multiple SNs occurred in 40.7% during surveillance. The 5-year cumulative incidence of metachronous multiple SNs was higher in patients with synchronous multiple SNs (54.2%) than in those without synchronous multiple SNs (46.4%). CONCLUSION Patients with UC with synchronous multiple SNs are at a higher risk of developing metachronous multiple SNs and may require a closer follow-up by total colonoscopy than patients without synchronous SNs.

SLC1A1, SLC16A9, and CNTN3 Are Potential Biomarkers for the Occurrence of Colorectal Cancer. BIOMED RESEARCH INTERNATIONAL 2020; 2020:1204605. [PMID: 32566650 PMCID: PMC7273407 DOI: 10.1155/2020/1204605] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 04/29/2020] [Accepted: 05/01/2020] [Indexed: 12/13/2022]
Abstract
Background This study is aimed at identifying unknown clinically relevant genes involved in colorectal cancer using bioinformatics analysis. Methods Original microarray datasets GSE107499 (ulcerative colitis), GSE8671 (colorectal adenoma), and GSE32323 (colorectal cancer) were downloaded from the Gene Expression Omnibus. Common differentially expressed genes were filtered from the three datasets above. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed, followed by construction of a protein-protein interaction network to identify hub genes. Kaplan-Meier survival analysis and TIMER database analysis were used to screen the genes related to the prognosis and tumour-infiltrating immune cells of colorectal cancer. Receiver operating characteristic curves were used to assess whether the genes could be used as markers for the diagnosis of ulcerative colitis, colorectal adenoma, and colorectal cancer. Results A total of 237 differentially expressed genes common to the three datasets were identified, of which 60 were upregulated, 125 were downregulated, and 52 genes that were inconsistently up- and downregulated. Common differentially expressed genes were mainly enriched in the cellular component of extracellular exosome and integral component of membrane categories. Eight hub genes, i.e., CXCL3, CXCL8, CEACAM7, CNTN3, SLC1A1, SLC16A9, SLC4A4, and TIMP1, were related to the prognosis and tumour-infiltrating immune cells of colorectal cancer, and these genes have diagnostic value for ulcerative colitis, colorectal adenoma, and colorectal cancer. Conclusion Three novel genes, CNTN3, SLC1A1, and SLC16A9 were shown to have diagnostic value with respect to the occurrence of colorectal cancer and should be verified in future studies.

Abstract
BACKGROUND Patients with Crohn's disease [CD] and ulcerative colitis [UC] are at increased risk for colorectal dysplasia [CRD] and colorectal cancer [CRC]. Adherence to CRC surveillance guidelines is reportedly low internationally. AIM To evaluate surveillance practices at the tertiary IBD Center of the McGill University Health Center [MUHC] and to determine CRD/CRC incidence. METHODS A representative inflammatory bowel disease cohort with at least 8 years of disease duration [or with primary sclerosing cholangitis] who visited the MUHC between July 1 and December 31, 2016 were included. Adherence to surveillance guidelines was compared to modified 2010 British Society of Gastroenterology guidelines. Incidence rates of CRC, high-grade dysplasia [HGD], low-grade dysplasia [LGD] and colorectal adenomas [CRA] were calculated based on pathology. RESULTS In total, 1356 CD and UC patients (disease duration: 12 [interquartile range: 6-22) and 10 [interquartile range: 5-19] years) were identified. The surveillance cohort consisted of 680 patients [296 UC and 384 CD]. Adherence to surveillance guidelines was 76/82% in UC/colonic CD. An adequate number of biopsies were taken in 54/54% of UC/colonic CD patients. The incidence of CRC/HGD in UC and CD with colonic involvement was 19.5/58.5 and 25.1/37.6 per 100,000 patient-years, respectively. The incidence of dysplasia before 8 years of disease duration was low in both UC/CD [19.5 and 12.5/100,000 patient-years] with no CRC detected. The CRA rate was 30/38% in UC/colonic CD. CONCLUSION High adherence to surveillance guidelines and low CRC and dysplasia, but not CRA rates were found, suggesting that adhering to updated, stratified, surveillance recommendations may result in low advanced neoplasia rates. The incidence of dysplasia before the start of surveillance was low.

Abstract
GOALS The aim of this study was to analyze the performance of Fuji Intelligent Color Enhancement (FICE) using the classification of Kudo in the differentiation of neoplastic and non-neoplastic raised lesions in ulcerative colitis (UC). BACKGROUND The Kudo classification of mucosal pit patterns is an aid for the differential diagnosis of colorectal polyps in the general population, but no systematic studies are available for all forms of raised lesions in UC. STUDY All raised, polypoid and nonpolypoid, lesions found during consecutive surveillance colonoscopies with FICE for long-standing UC were included. In the primary prospective analysis, the Kudo classification was used to predict the histology by FICE. In a post hoc analysis, further endoscopic markers were also explored. RESULTS Two hundred and five lesions (mean size, 8 mm; range, 2 to 30 mm) from 59 patients (mean age, 56 y; range, 21 to 79 y) were analyzed. Twenty-three neoplastic (11%), 18 hyperplastic (9%), and 164 inflammatory (80%) lesions were found. Thirty-one lesions (15%), none of which were neoplastic, were unclassifiable according to Kudo. After logistic regression, a strong negative association resulted between endoscopic activity and neoplasia, whereas the presence of a fibrin cap was significantly associated with endoscopic activity. Using FICE, the sensitivity, specificity, and positive and negative likelihood ratios of the Kudo classification were 91%, 76%, 3.8, and 0.12, respectively. The corresponding values by adding the fibrin cap as a marker of inflammation were 91%, 93%, 13, and 0.10, respectively. CONCLUSIONS FICE can help to predict the histology of raised lesions in UC. A new classification of pit patterns, based on inflammatory markers, should be developed in the setting of UC to improve the diagnostic performance.

Abstract
Background Patients with ulcerative colitis (UC) have an increased risk of colorectal cancer. Scarce data regarding the development of adenomas in these patients are available both for normal and colitic mucosa. Objective The objective of this article is to evaluate the prevalence of adenomatous polyps and associated risk factors in patients with UC. Methods Patients with UC were identified from the databases of two tertiary referral centers. Medical, endoscopic and histologic reports were reviewed. Results A total of 403 patients were included (53% male; 33% extensive colitis) and 1065 colonoscopies (median per patient, 2) were recorded and analyzed. Seventy-four adenomas in 47 patients (11.7%) and three cases of colorectal cancer were found during a median follow-up of 6.3 years. The cumulative risk of colorectal adenoma was 4.7%, 16.7%, 23.6% and 34.4% at 10, 20, 30 and 40 years from UC diagnosis, respectively. The cumulative risk of developing metachronous colorectal adenoma was 66.7%, 87.9%, and 90.9% at 5, 10, and 15 years from first adenoma detection. Older age at UC diagnosis and longer disease duration were independent risk factors for colorectal adenoma development. Conclusions The prevalence of colorectal adenomas among UC patients seems to be higher than previously reported, although lower than in the background population.

Abstract
BACKGROUND AND AIMS Patients with ulcerative colitis (UC) are prone to colorectal cancer and dysplastic polyps and also have sporadic adenomas. There is scant information, however, relating the prevalence of sporadic adenomas in UC patients compared with normal subjects. The aim of this study was to assess the prevalence of all dysplastic lesions in UC and compare the prevalence of adenomas to that in the general population. METHODS A single-center retrospective study, in which all patients with diagnosed UC were followed during a ten-year period. The incidence of polyps and colorectal cancers were recorded and compared to that of an age-matched group in the general population who had screening colonoscopy. RESULTS A total of 229 UC patients were included compared with 450 age-matched subjects who underwent a single colonoscopy. The average number of colonoscopies per UC patient was 3. The rate of sporadic adenomas among UC patients (9.6%), as well as the rate of all dysplastic polyps (11.2%) in these patients, were significantly lower than the rate of adenomas among the control population (24%; OR 0.33-0.44; P<0.0001). Despite this, the rates of colon cancer were comparable between the groups (2.1% vs. 1.5%, P=0.55). CONCLUSIONS In spite of the observed lower rate of dysplastic polyps in UC patients, this should not preclude tight surveillance in this high-risk population.

Abstract
BACKGROUND AND AIMS Literature data about the outcome of segmental colitis associated with diverticulosis (SCAD) are scarce. Our aim was to assess the clinical outcome of SCAD according to the type of disease. PATIENTS/METHODS Twenty-seven SCAD patients underwent a 5-year follow-up (13 males, 14 females; mean age, 63.71 years; range, 50-85 years). Eleven patients were affected by type A, eight by type B, four by type C and four by type D SCAD. During the follow-up, all type B, C, and D patients were under continuous medical treatment. Five type A patients refused any maintaining treatment, but accepted to undergo the clinical, endoscopic, and histological follow-up. RESULTS/FINDINGS Five type A patients taking therapy (83.33%), two type A not taking therapy (50%), all type C patients (100%), five type B patients (62.5%) and none of type D (0%) were under continuous remission at the end of the follow-up. All type D patients required further steroid course to obtain remission, and two patients required azathioprine to maintain remission. INTERPRETATIONS/CONCLUSIONS: SCAD B and D patients fail to maintain long-term remission, often requiring immunosuppressive treatment. SCAD A and C patients show a more benign course; however, long-term treatment guarantees longer remission also in those patients.

Abstract
OBJECTIVE There is an increased risk of colorectal cancer in patients with inflammatory bowel disease (IBD). The aim of this study was to compare the prevalence of left sided adenomas in patients with IBD aged 55-64 years with a local age matched control population. METHOD A review of clinical notes. The prevalence of adenomas in patients with IBD attending for either sigmoidoscopy or colonoscopy was compared with local age matched controls that participated in the national screening trial for colorectal cancer with flexible sigmoidoscopy. RESULTS Of 106 patients (61 male, 45 female, mean age of 59 years), 80 suffered from ulcerative colitis, 20 from Crohn's disease, and six from indeterminate colitis. All patients had undergone at least one flexible sigmoidoscopy and 75 had a colonoscopy. Distal adenomas were found in three patients with ulcerative colitis compared with 67 of 749 controls (2.8% v 8.9%, chi(2) = 4.6, p = 0.03). CONCLUSIONS The results suggest that distal adenomatous polyps are rare in patients aged 55-64 years with IBD compared with a control population. This supports the hypothesis that lesions other than polyps are important for the development of colorectal cancer in patients with IBD.
