Abstract
BACKGROUND IPAA is often required for patients with ulcerative colitis or familial adenomatous polyposis after colectomy. This procedure reduces but does not completely eliminate the risk of neoplasia. OBJECTIVE This study focuses on the histopathology of neoplasia in the ileal pouch, rectal cuff, and anal transition zone. DATA SOURCES We performed a MEDLINE search for English-language studies published between 1981 and 2022 using the PubMed search engine. The terms "ileal pouch-anal anastomosis," "pouchitis," "pouch dysplasia," "pouch lymphoma," "pouch squamous cell carcinoma," "pouch adenocarcinoma," "pouch neoplasia," "dysplasia of rectal cuff," and "colitis-associated dysplasia" were used. STUDY SELECTION Human studies of neoplasia occurring in the pouch and para-pouch were selected, and the full text was reviewed. Comparisons were made within and across studies, with key concepts selected for inclusion in this article. CONCLUSIONS Neoplasia in the pouch is a rare complication in patients with IPAA. Annual endoscopic surveillance is recommended for familial adenomatous polyposis patients and ulcerative colitis patients with a history of prior dysplasia or carcinoma. In familial adenomatous polyposis, dysplastic polyps of the pouch are visible and readily amenable to endoscopic removal; however, glandular dysplasia in the setting of ulcerative colitis may be invisible on endoscopy. Therefore, random biopsies and adequate tissue sampling of the pouch and rectal cuff are recommended in this setting. The histological diagnosis of IBD-associated dysplasia can be challenging and should be confirmed by at least 1 expert GI pathologist. See video from the symposium.

Abstract
One of the earliest applications of flow cytometry was the measurement of DNA content in cells. This method is based on the ability to stain DNA in a stoichiometric manner (i.e., the amount of stain is directly proportional to the amount of DNA within the cell). For more than 40years, a number of studies have consistently demonstrated the utility of DNA flow cytometry as a potential diagnostic and/or prognostic tool in patients with most epithelial tumors, including pre-invasive lesions (such as dysplasia) in the gastrointestinal tract. However, its availability as a clinical test has been limited to few medical centers due to the requirement for fresh tissue in earlier studies and perceived technical demands. However, more recent studies have successfully utilized formalin-fixed paraffin-embedded (FFPE) tissue to generate high-quality DNA content histograms, demonstrating the feasibility of this methodology. This review summarizes step-by-step methods on how to perform DNA flow cytometry using FFPE tissue and analyze DNA content histograms based on the published consensus guidelines in order to assist in the diagnosis and/or risk stratification of many different epithelial tumors, with particular emphasis on dysplasia associated with Barrett's esophagus and inflammatory bowel disease.

Abstract
The term nonconventional dysplasia has been coined to describe several underrecognized morphologic patterns of epithelial dysplasia in inflammatory bowel disease (IBD), but to date, the full recognition of these newly characterized lesions by pathologists is uneven. The identification of nonconventional dysplastic subtypes is becoming increasingly important, as they often present as invisible/flat dysplasia and are more frequently associated with advanced neoplasia than conventional dysplasia on follow-up. This review describes the morphologic, clinicopathologic, and molecular characteristics of seven nonconventional subtypes known to date, as well as their potential significance in the clinical management of IBD patients.

Molecular characterization of visible low-grade dysplastic lesions in patients with inflammatory bowel disease. Hum Pathol 2023; 135:108-116. [PMID: 36754311 DOI: 10.1016/j.humpath.2023.01.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 01/18/2023] [Accepted: 01/26/2023] [Indexed: 02/08/2023]
Abstract
We studied pathogenic gene mutations and tumor mutation burden (TMB) in visible low-grade dysplastic lesions in patients with inflammatory bowel disease (IBD). The dysplastic lesions with histologically normal mucosa in the background (group 1) were compared with dysplastic lesions occurring either in a background of chronic active colitis (group 2) or associated with synchronous carcinomas regardless of the status of the background mucosa (group 3). The TMB in group 3 was consistently higher in comparison to the group 1 and group 2 lesions, although the difference was not statistically significant. There also seem to be different mutation profiles between the groups, indicating different pathways of tumor pathogenesis. More frequent APC mutations were seen in group 1 as compared to other groups and TP53 mutations were seen in groups 2 and 3, but none in group 1. Molecular characterization could potentially be used as an ancillary prognostic marker in challenging cases to guide the further management of IBD patients with visible dysplastic lesions.

Abstract
BACKGROUND To date, the optimal management of patients with inflammatory bowel disease (IBD) and flat low-grade dysplasia (fLGD) of the colon or rectum remains controversial. METHODS A systematic review was reported in accordance with PRISMA 2020 (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). Patients diagnosed with fLGD on surveillance endoscopy were pooled from studies published between 2000 and 2020. Advanced neoplasia was defined by the presence of HGD, CRC or small bowel adenocarcinoma detected on subsequent surveillance endoscopy or from examination of resection specimens. We estimated the pooled annual incidence rate of colorectal cancer (CRC) and advanced neoplasia, and the risk factors associated with neoplastic progression. RESULTS We identified 24 articles and 738 IBD patients were diagnosed with fLGD on endoscopy. Two hundred thirty-six patients (32%) underwent immediate surgery with surgical specimens demonstrating CRC in 8 patients (pooled prevalence, 8.66%; 95% CI 3.58-19.46) and HGD (high grade dysplasia) in 11 patients (pooled prevalence, 13.97%; 95% CI 5.65-30.65). Five hundred-two patients (68%) underwent endoscopic surveillance with 63 patients with fLGD progressing to advanced neoplasia during endoscopic surveillance (38 HGD, 24 CRC and one patient developing small bowel adenocarcinoma). The mean duration of follow-up after fLGD diagnosis was 71 months (10.9-212). The pooled incidence of CRC and advanced neoplasia was 0.5 (95% CI 0.23-0.77) and 1.71 per 100 patient-year (95% CI 0.88-2.54) respectively. The use of corticosteroids and location of fLGD in the distal colon were significantly associated with neoplastic progression. CONCLUSIONS This study provides a summary incidence rate of CRC and advanced neoplasia in patients with IBD and fLGD to inform surgeons' and endoscopists' decision-making thus reducing potential ineffective treatments.

Abstract
Inflammatory bowel diseases (IBD), including Crohn disease and ulcerative colitis, are chronic inflammatory conditions of the gastrointestinal tract. Individuals with IBD are at increased risk for several malignancies originating in the intestine, such as colorectal cancer, small bowel adenocarcinoma, intestinal lymphoma, and anal cancer. There are also several extraintestinal malignancies associated with IBD and IBD therapies, including cholangiocarcinoma, skin cancer, hematologic malignancies, genitourinary cancer, cervical cancer, and prostate cancer. The authors summarize the risk of cancer in patients with IBD, diagnosis and management of colorectal neoplasia in IBD, and management of patients with IBD and active or recent cancer.

Abstract
BACKGROUND Due to limited research on the natural history of indefinite for dysplasia (IND) and low-grade dysplasia (LGD) in inflammatory bowel disease (IBD), the management of these patients is controversial. AIMS This systematic review and meta-analysis aimed to estimate the incidence and identify the risk factors for advanced neoplasia in IBD patients with IND and LGD. METHODS PubMed, Embase and Cochrane Central Register of Controlled Trials were searched until 24 December, 2021, to identify studies that reported pathological results of follow-up colonoscopy or surgery in IBD patients with IND and LGD. The main outcomes were the incidence and risk factors for advanced neoplasia in IBD patients with IND and LGD. RESULTS Based on the analysis of 38 studies, the pooled incidences of advanced neoplasia in IBD patients with IND and LGD were 9.9% (95% CI 4.4%-15.4%) and 10.7% (95% CI 7.0%-14.4%) respectively. The risk factors for advanced neoplasia in IND patients were primary sclerosing cholangitis (PSC) and aneuploidy. The risk factors for advanced neoplasia in LGD patients included male, PSC, previous IND, colonic stricture, index lesion ≥1 cm, distal location, multifocal lesions, distal and flat lesions, nonpolypoid/flat lesions and invisible lesions. CONCLUSIONS The incidence of advanced neoplasia was similar between IND and LGD in IBD patients, as high as one in ten, so more rigorous surveillance is also suggested in IND patients. Since the effects of most factors were derived from the pooled results of only two to three studies, further research was needed to confirm our results.

Abstract
Patients with inflammatory bowel disease (IBD) are at increased risk of developing colorectal cancer (CRC), despite decreases in CRC incidence in recent years. Chronic inflammation is the driver of neoplastic progression, resulting in dysplastic precursor lesions that may arise in multiple areas of the colon through a process of field cancerization. Colitis-associated CRC shares many molecular similarities with sporadic CRC, and preclinical investigations have demonstrated a potential role for the microbiome in concert with the host immune system in the development of colitis-associated colorectal cancer (CAC). Some unique molecular differences occur in CAC, but their role in the pathogenesis and behavior of inflammation-associated cancers remains to be elucidated. Nonconventional types of dysplasia have been increasingly recognized, but their natural history is not well defined, and they have not been incorporated into surveillance algorithms. The concept of cumulative inflammatory burden highlights the importance of considering histologic inflammation over time as an important risk factor for CAC. Dysplasia is arguably the most important risk factor for developing CAC, and advances have been made in the endoscopic detection and removal of precancerous lesions, thereby deferring or avoiding surgical resection. Some of the agents used to treat IBD are chemopreventive. It is hoped that by gaining better control of the underlying inflammation with newer medications and better endoscopic detection and management, a more sophisticated appreciation of clinicopathologic risk factors, and growing awareness of the genetic, immunologic, and environmental causes of colitis- associated neoplasia, that colitis-associated colorectal neoplasia will become even more predictable and manageable in the coming years.

Abstract
Patients with inflammatory bowel disease are at significantly increased risk of dysplasia and colorectal cancer (CRC). The early detection, histologic grading, and removal of dysplasia plays a critical role in preventing the development of CRC. With advances in endoscopic visualization and resection techniques, colectomy is no longer recommended to manage dysplasia, unless surveillance colonoscopy detects flat/invisible dysplasia (either high-grade dysplasia or multifocal low-grade dysplasia) or an endoscopically unresectable lesion. Although there are numerous review articles and book chapters on the morphologic criteria of conventional (intestinal type) dysplasia, the most well-recognized form of dysplasia, at least 7 distinct nonconventional morphologic patterns of epithelial dysplasia have been recently described in inflammatory bowel disease. Most practicing pathologists are not familiar with these nonconventional subtypes and thus, may even overlook some of these dysplastic lesions as benign or reactive. However, the recognition of these subtypes is important, as some of them appear to have a high risk of developing advanced neoplasia (high-grade dysplasia or CRC) and often show molecular alterations characteristic of advanced neoplasia. This review briefly describes the morphologic criteria of conventional dysplasia but predominantly focuses on all 7 nonconventional subtypes as well as our understanding of their clinicopathologic and molecular features that can assist in their risk stratification.

Abstract
Ulcerative colitis (UC) is a risk factor for the development of inflammation-associated dysplasia or colitis-associated neoplasia (CAN). This transformation results from chronic inflammation, which induces changes in epithelial proliferation, survival, and migration via the induction of chemokines and cytokines. There are notable differences in genetic mutation profiles between CAN in UC patients and sporadic colorectal cancer in the general population. Colonoscopy is the cornerstone for surveillance and management of dysplasia in these patients. There are several modalities to augment the quality of endoscopy for the better detection of dysplastic or neoplastic lesions, including the use of high-definition white-light exam and image-enhanced colonoscopy, which are described in this review. Clinical practice guidelines regarding surveillance strategies in UC have been put forth by various GI societies, and overall, there is agreement between them except for some differences, which we highlight in this article. These guidelines recommend that endoscopically detected dysplasia, if feasible, should be resected endoscopically. Advanced newer techniques, such as endoscopic mucosal resection and endoscopic submucosal dissection, have been utilized in the treatment of CAN. Surgery has traditionally been the mainstay of treating such advanced lesions, and in cases where endoscopic resection is not feasible, a proctocolectomy, followed by ileal pouch-anal anastomosis, is generally recommended. In this review we summarize the approach to surveillance for cancer and dysplasia in UC. We also highlight management strategies if dysplasia is detected.

Abstract
BACKGROUND Recommendations regarding management of colorectal dysplasia in the setting of IBD continue to evolve. OBJECTIVE This study aimed to determine the rate of progression from dysplasia to adenocarcinoma, specifically focusing on the differences in unifocal and multifocal low-grade dysplasia and dysplasia found on random biopsy versus targeted biopsies. DESIGN This is a retrospective review. SETTING This study was conducted at an IBD referral center. PATIENTS All adult patients (≥18 years of age) with a known diagnosis of either ulcerative colitis or Crohn's disease, who underwent a surveillance colonoscopy between January 1, 2010 and January 1, 2019, were selected. MAIN OUTCOMES MEASURES The primary outcomes measured were the progression of dysplasia and the risk factors for progression. RESULTS A total of 23,751 surveillance colonoscopies were performed among 12,289 patients between January 1, 2010 and January 1, 2019. The mean age at colonoscopy was 52.1 years (SD 16.9 years), 307 patients (2.5%) had a history of primary sclerosing cholangitis, and 3887 (3.15%) had a family history of colorectal cancer. There was a total of 668 patients (5.4%) with low-grade dysplasia, 76 patients (0.62%) with high-grade dysplasia, and 68 patients (0.55%) with adenocarcinoma in the series. The 1-, 2-, and 5-year cumulative incidence rate of progressing from low-grade dysplasia to high-grade dysplasia were 1.6%, 4.8%, and 7.8%. The 1- and 2-year cumulative incidence rates of progressing from low-grade dysplasia to adenocarcinoma were 0.7% and 1.6%. There were no significant differences in unifocal and multifocal progression. Primary sclerosing cholangitis, ulcerative colitis, male sex, and advanced age were all found to be significant risk factors for neoplasia on multivariable analysis. LIMITATIONS A retrospective database was a source of information. CONCLUSION Progression of low-grade dysplasia to adenocarcinoma, regardless of its being unifocal or multifocal, remains very low in the setting of adequate surveillance and medical management. The presence of multifocal low-grade dysplasia should not change the decision making to pursue ongoing endoscopic surveillance versus proctocolectomy. Patients who had primary sclerosing cholangitis with dysplasia found on random biopsies may be at highest risk for dysplasia progression. See Video Abstract at http://links.lww.com/DCR/A649.

La edad media en el momento de la colonoscopia fue de 52,1 años (DE 16,9 años), 307 pacientes (2,5%) tenían antecedentes de colangitis esclerosante primaria y 3887 (3,15%) tenían antecedentes familiares de cáncer colorrectal. Hubo un total de 668 pacientes (5,4%) con displasia de bajo grado, 76 pacientes (0,62%) con displasia de alto grado y 68 pacientes (0,55%) con adenocarcinoma en la serie. La tasa de incidencia acumulada de 1, 2, 5 años de progresión de displasia de bajo grado a displasia de alto grado fue del 1,6%, 4,8% y 7,8%. Las tasas de incidencia acumulada de 1 y 2 años de progresión de displasia de bajo grado a adenocarcinoma fueron 0,7% y 1,6%, respectivamente. No hubo diferencias significativas en la progresión unifocal y multifocal. Se encontró que la colangitis esclerosante primaria, la colitis ulcerosa, el sexo masculino y la edad avanzada eran factores de riesgo significativos de neoplasia en el análisis multivariable.LIMITACIONES:Base de datos retrospectiva.CONCLUSIÓN:La progresión de la displasia de bajo grado a adenocarcinoma, independientemente de que sea unifocal o multifocal, sigue siendo muy baja en el contexto de una vigilancia y un tratamiento médico adecuados. La presencia de displasia multifocal de bajo grado no debería cambiar la toma de decisión para continuar con vigilancia endoscópica continua o realizar la proctocolectomía. Los pacientes con colangitis esclerosante primaria y displasia encontrada en biopsias aleatorias pueden tener una mayor progresión de la displasia.

Abstract
BACKGROUND The Japanese Society of Gastroenterology (JSGE) published ''Daicho Polyp Shinryo Guideline 2014'' in Japanese and a part of this guideline was published in English as "Evidence-based clinical practice guidelines for management of colorectal polyps" in the Journal of Gastroenterology in 2015. A revised version of the Japanese-language guideline was published in 2020, and here we introduce a part of the contents of revised version. METHODS The guideline committee discussed and drew up a series of clinical questions (CQs). Recommendation statements for the CQs were limited to items with multiple therapeutic options. Items with established conclusions that had 100% agreement with previous guidelines (background questions) and items with no (or old) evidence that are topics for future research (future research questions: FRQs) were given descriptions only. To address the CQs and FRQs, PubMed, ICHUSHI, and other sources were searched for relevant articles published in English from 1983 to October 2018 and articles published in Japanese from 1983 to November 2018. The Japan Medical Library Association was also commissioned to search for relevant materials. Manual searches were performed for questions with insufficient online references. RESULTS The professional committee created 18 CQs and statements concerning the current concept and diagnosis/treatment of various colorectal polyps, including their epidemiology, screening, pathophysiology, definition and classification, diagnosis, management, practical treatment, complications, and surveillance after treatment, and other colorectal lesions (submucosal tumors, nonneoplastic polyps, polyposis, hereditary tumors, ulcerative colitis-associated tumors/carcinomas). CONCLUSIONS After evaluation by the moderators, evidence-based clinical practice guidelines for management of colorectal polyps were proposed for 2020. This report addresses the therapeutic related CQs introduced when formulating these guidelines.

Abstract
The early detection and grading of dysplasia is the current standard of care to minimize mortality from colorectal cancer (CRC) in patients with inflammatory bowel disease. With the development of advanced endoscopic resection techniques, colectomy is now reserved for patients with invisible/flat dysplasia (either high-grade [HGD] or multifocal low-grade dysplasia) or endoscopically unresectable lesions. Although most pathologists are familiar with the morphologic criteria of conventional (intestinal type) dysplasia, the most well-recognized form of dysplasia, an increasing number of diagnostic material has led to the recognition of several different morphologic patterns of epithelial dysplasia. The term “non-conventional” dysplasia has been coined to describe these changes, but to date, the recognition and full appreciation of these novel forms of dysplasia by practicing pathologists is uneven. The recognition of these non-conventional subtypes is becoming increasingly important, as some of them appear to have a higher risk of developing HGD or CRC than conventional dysplasia or sporadic adenomas. This review describes the morphologic characteristics of all seven non-conventional subtypes that have been reported to date as well as our current understanding of their clinicopathologic and molecular features that distinguish them from conventional dysplasia or sporadic adenomas.

Abstract
BACKGROUND We sought to determine the rate of progression from dysplasia to adenocarcinoma in ulcerative colitis [UC] vs Crohn's diseases [CD] and describe the risk factors unique to each. METHODS All adult patients [≥18 years] with a known diagnosis of either UC or CD who underwent a surveillance colonoscopy between January 1, 2010 and January 1, 2020 were included. RESULTS A total of 23 751 surveillance colonoscopies were performed among 12 289 patients between January 1, 2010 and January 1, 2020; 6909 [56.2%] had a diagnosis of CD and 5380 [43.8%] had a diagnosis of UC. There were a total of 668 patients [5.4%] with low-grade dysplasia [LGD], 76 patients [0.62%] with high-grade dysplasia [HGD], and 68 patients [0.55%] with adenocarcinoma in the series; the majority of the dysplastic events were located in the right colon. Significantly more UC patients had a dysplastic event, but the rate of LGD and HGD dysplasia progression to adenocarcinoma was not significantly different in CD or UC [p = 0.682 and p = 1.0, respectively]. There was no significant difference in the rate of progression from LGD/HGD to adenocarcinoma based on random biopsies vs targeted biopsies of visible lesions [p = 0.37]. However, the rate of progression from LGD vs HGD to adenocarcinoma was significantly greater for HGD [p < 0.001]. CONCLUSION While more UC patients were found to have neoplasia on colonoscopy, the rate of progression from LGD and HGD to adenocarcinoma was equivalent in UC and CD, suggesting that endoscopic surveillance strategies can remain consistent for all IBD patients.

Abstract
Longstanding and extensive ulcerative colitis (UC) are associated with the subsequent development of colorectal cancer (CRC). This article summarizes key strategies for colonoscopic surveillance, the most widely used and evidence-based method of CRC prevention. As currently constituted and practiced, surveillance examinations every 1 to 3 years with lesion detection and removal using high-definition endoscopic systems with or without pancolonic spray-dye chromoendoscopy is the best method for mitigating the development of CRC morbidity and mortality. For patients with primary sclerosing cholangitis with UC, surveillance should begin at the time of diagnosis and colonoscopy should be performed annually.

Abstract
INTRODUCTION Endoscopy plays a key role in the management of inflammatory bowel disease (IBD). There is an increased need for quality assurance programs that evaluate the quality, safety and patient experiences of endoscopy, by assessing procedural and clinical outcomes. AREAS COVERED This review aims to summarize the most important quality indicators of endoscopy in IBD patients and could serve as the basis to improve quality endoscopic procedures and patients' perception of endoscopy in the future. However, further studies and consensus reports are necessary to standardize the quality of care in the endoscopy unit of all IBD centers. EXPERT COMMENTARY Developing an understanding of the patient-reported perception is important for both clinicians and patients, as it facilitates patient engagement with their care. Moreover, implementing education in reporting is crucial f and the use of verifiable databases, generated from electronic reporting systems, should be encouraged rather than unverified self-reporting, to have greater validity for documenting and to formally evaluate endoscopic practice data with audits. The use of artificial intelligence may improve the quality of endoscopy, by increasing the adenoma detection rate and helping endoscopists in the challenging differentiation between inflammatory and neoplastic lesions.

Abstract
INTRODUCTION The prognosis of dysplasia in patients with IBD is largely determined from observational studies from the pre-videoendoscopic era (pre-1990s) that does not reflect recent advances in endoscopic imaging and resection. AIMS To better understand the risk of synchronous colorectal cancer and metachronous advanced neoplasia (ie high-grade dysplasia or cancer) associated with dysplasia diagnosed in the videoendoscopic era, and to stratify risk according to a lesion's morphology, endoscopic resection status or whether it was incidentally detected on biopsy of macroscopically normal colonic mucosa (ie invisible). METHODS A systematic search of original articles published between 1990 and February 2020 was performed. Eligible studies reported on incidence of advanced neoplasia at follow-up colectomy or colonoscopy for IBD-dysplasia patients. Quantitative and qualitative analyses were performed. RESULTS Thirty-three studies were eligible for qualitative analysis (five for the meta-analysis). Pooled estimated proportions of incidental synchronous cancers found at colectomy performed for a pre-operative diagnosis of visible high-grade dysplasia, invisible high-grade dysplasia, visible low-grade dysplasia and invisible low-grade dysplasia were 13.7% (95% CI 0.0-54.1), 11.4% (95% CI 4.6-20.3), 2.7% (95% CI 0.0-7.1) and 2.4% (95% CI 0.0-8.5) respectively. The lowest incidences of metachronous advanced neoplasia, for dysplasia not managed with immediate colectomy but followed up with surveillance, tended to be reported by the studies where high definition imaging and/or chromoendoscopy was used and endoscopic resection of visible dysplasia was histologically confirmed. CONCLUSIONS The prognosis of IBD-dysplasia diagnosed in the videoendoscopic era appears to have been improved but the quality of evidence remains low. Larger, prospective studies are needed to guide management. PROSPERO registration no: CRD42019105736.

Abstract
BACKGROUND & AIMS Little is known about the clinical significance of indefinite dysplasia (IND) in patients with inflammatory bowel diseases (IBD) undergoing colonoscopic surveillance for colorectal neoplasia. METHODS We conducted a retrospective cohort analysis of 492 patients with colonic IBD for 8 or more years or concomitant primary sclerosing cholangitis, with no history of advanced colorectal neoplasia (high-grade dysplasia or colorectal cancer) or colectomy, undergoing colorectal neoplasia surveillance at a tertiary IBD referral center from 2001 through 2017. Subjects received consistent histopathologic grading of dysplasia. We collected data on time to development of (advanced) colorectal neoplasia or colectomy using Kaplan Meier methods. We identified factors independently associated with (advanced) colorectal neoplasia with multivariable Cox regression analysis. RESULTS After 2149 person-years of follow-up, 53 patients (10.8%) received a diagnosis of IND without prior or synchronous low-grade dysplasia (LGD). Compared to patients without dysplasia, patients with IND had a significantly higher risk of advanced colorectal neoplasia (adjusted hazard ratio, 6.85; 95% CI, 1.78-26.4) and colorectal neoplasia (adjusted hazard ratio, 3.25; 95% CI, 1.50-7.05), but not colectomy (P = .78). Compared to IND, LGD was associated with a significantly higher risk of advanced colorectal neoplasia (P = .05). Following a diagnosis of no dysplasia, IND only, or LGD, the incidence rates of advanced colorectal neoplasia were 0.4% per patient-year, 3.1% per patient-year, and 8.4% per patient-year, respectively. CONCLUSIONS In a retrospective analysis of patients with IBD undergoing colorectal neoplasia surveillance with consistent histopathologic grading of dysplasia, IND was independently associated with a significant increase in risk of advanced colorectal neoplasia. These findings require validation and if confirmed, a reappraisal of the colorectal neoplasia surveillance guidelines.

Abstract
Patients with inflammatory bowel disease (IBD) are at an increased risk of developing intestinal neoplasia-particularly colorectal neoplasia, including dysplasia and colorectal cancer (CRC)-as a primary consequence of chronic inflammation. While the current incidence of CRC in IBD is lower compared with prior decades, due, in large part, to more effective therapies and improved colonoscopic technologies, CRC still accounts for a significant proportion of IBD-related deaths. The focus of this review is on the pathogenesis; epidemiology, including disease- and patient-related risk factors; diagnosis; surveillance; and management of IBD-associated neoplasia.

Abstract
BACKGROUND AND AIMS The long-term risk of high-grade dysplasia [HGD] and colorectal cancer [CRC] following low-grade dysplasia [LGD] in inflammatory bowel disease [IBD] patients is relatively unknown. We aimed to determine the long-term cumulative incidence of advanced neoplasia [HGD and/or CRC], and to identify risk factors for advanced neoplasia in a nationwide IBD cohort with a history of LGD. METHODS This is a nationwide cohort study using data from the Dutch National Pathology Registry [PALGA] to identify all IBD patients with LGD between 1991 and 2010 in the Netherlands. Follow-up data were collected until January 2016. We determined the cumulative incidence of advanced neoplasia and identified risk factors via multivariable Cox regression analysis. RESULTS We identified 4284 patients with colonic LGD with a median follow-up of 6.4 years after initial LGD diagnosis. The cumulative incidence of subsequent advanced neoplasia was 3.6, 8.5, 14.4 and 21.7%, after 1, 5, 10 and 15 years, respectively. The median time to develop advanced neoplasia after LGD was 3.6 years. Older age [≥ 55 years] at moment of LGD (hazard ratio [HR] 1.73, 95% confidence interval [CI] 1.44-2.06), male sex [HR 1.33, 95% CI 1.10-1.60], and follow-up at an academic [vs non-academic] medical centre [HR 1.37, 95% CI 1.07-1.76] were independent risk factors for advanced neoplasia following LGD. CONCLUSIONS In a large nationwide cohort with long-term follow-up of IBD patients with LGD, the cumulative incidence of advanced neoplasia was 21.7% after 15 years. Older age at LGD [≥55 years], male sex and follow-up by a tertiary IBD referral centre were independent risk factors for advanced neoplasia development after initial LGD.

Abstract
This article begins with a brief overview of risk factors for colorectal neoplasia in inflammatory bowel disease to concretize the approach to risk stratification. It then provides an up-to-date review of diagnosis and management of dysplasia in inflammatory bowel disease, which integrates new and emerging data in the field. This is particularly relevant in an era of increased attention to cost- and resource-containment from the health systems vantage point, coupled with a heightened prioritization of patient quality of life and shared decision-making. Also provided is a brief discussion of the status of newer therapeutic techniques, such as endoscopic submucosal dissection.

Abstract
BACKGROUND AND AIMS The clinical significance of 'indefinite for dysplasia' [IND] in patients with inflammatory bowel disease remains unclear. Currently, no biomarker can reliably differentiate reactive changes from true dysplasia and/or risk stratify IND. METHODS A total of 52 IND colon biopsies were analysed by DNA flow cytometry. The follow-up result of each biopsy was determined by reviewing all subsequent biopsies and endoscopic reports for the occurrence of high-grade dysplasia [HGD] or colorectal cancer [CRC] at the site of previous biopsy or in the same segment of colon. RESULTS The overall 1-, 3-, 5-, and 7-year detection rates of HGD or CRC in all 52 IND cases were 4.6% (95% confidence interval [CI], 0.0%-10.6%), 18.2% [95% CI, 3.5%-30.7%], 26.3% [95% CI, 8.4%-40.7%], and 31.6% [95% CI, 11.2%-47.4%], respectively. More interestingly, 10.6% of IND cases with aneuploidy were subsequently found to have HGD or CRC within 1 year [95% CI, 0.0%-23.7%], with 36.4% [95% CI, 7.1%-56.5%], 51.7% [95% CI, 16.1%-72.2%], and 59.8% [95% CI, 21.4%-79.5%] detected within 3, 5, and 7 years, respectively. By comparison, in the setting of normal DNA content, 1-, 3-, 5-, and 7-year detection rates of HGD or CRC were 0.8% [95% CI, 0.0%-2.7%], 3.3% [95% CI, 0.0%-9.6%], 5.2% [95% CI, 0.0%-14.7%], and 6.5% [95% CI, 0.0%-18.1%], respectively. Only the presence of aneuploidy was found to be a significant predictor of HGD or CRC with the estimated univariate and multivariate hazard ratios of 13.8 [p = 0.016] and 50.3 [p = 0.010], respectively. CONCLUSIONS IND may not be a low-risk condition for HGD or CRC. In this regard, the presence of aneuploidy can identify a subset of IND cases that are at increased risk for subsequent detection of HGD or CRC.

Abstract
Compared with the general population, patients with inflammatory bowel disease [IBD] have an increased risk of developing colorectal cancer. Molecular mechanisms underlying colorectal carcinogenesis in the setting of IBD are not well understood. However, modern molecular investigative tools have facilitated the identification of features that help distinguish IBD-related carcinoma from sporadic carcinoma. Moreover, with advances in endoscopic technology and improved understanding of the natural history, the management of colorectal neoplastic lesions in IBD patients has evolved. This review discusses the clinicopathological and molecular features of colorectal neoplastic lesions complicating IBD. Chronic inflammation is believed to promote the development of neoplasia, partly by producing reactive oxygen and nitrogen species [ROS and NOS], which may interact with genes involved in carcinogenetic pathways. Furthermore, alterations in microbiota and in the innate and adaptive immune responses might contribute to this process, particularly by initiating, regulating, and sustaining chronic inflammation. Earlier detection and better characterization of neoplastic colorectal lesions complicating IBD and a better knowledge of the molecular mechanisms underlying carcinogenesis in this setting should facilitate improvements in the risk stratification of patients with longstanding IBD and in the management of dysplastic and malignant colorectal lesions that arise in this setting.

Abstract
There are few abbreviations in surgical pathology that are associated with as much immediate recognition, frustration, and confusion as DALM (dysplasia-associated lesion or mass). DALM is used to describe endoscopically visible dysplastic lesions in the surveillance of patients with inflammatory bowel disease. However, the diagnosis of DALM has been complicated by the inconsistent criteria and use of terminology for describing dysplasia in inflammatory bowel disease, and a tendency to relate DALM with the need for colectomy. Fortunately, advancements in both endoscopic visualization and local excision capability have allowed for a more defined management of dysplasia in inflammatory bowel disease. In 2015, the Surveillance for Colorectal Endoscopic Neoplasia Detection and Management in Inflammatory Bowel Disease Patients International Consensus Recommendations (SCENIC) Development Panel, a panel of predominantly expert gastroenterologists and endoscopists in surveillance of inflammatory bowel disease, published a consensus statement. One recommendation was to abandon DALM-related terminology in favor of endoscopic descriptors modified from the Paris endoscopic classification. Recommendations on surveillance and management of dysplastic lesions were also provided. Nevertheless, interval carcinomas and metachronous neoplasia remain persistent issues. This review aims to provide an update on the post-DALM terminology and management recommendations for inflammatory bowel disease-associated dysplasia necessary for a meaningful communication between pathologists and clinicians.

High Risk of Advanced Colorectal Neoplasia in Patients With Primary Sclerosing Cholangitis Associated With Inflammatory Bowel Disease. Clin Gastroenterol Hepatol 2018; 16:1106-1113.e3.

Abstract
BACKGROUND & AIMS Patients with inflammatory bowel disease (IBD) and primary sclerosing cholangitis (PSC, termed PSC-IBD) are at increased risk for colorectal cancer, but their risk following a diagnosis of low-grade dysplasia (LGD) is not well described. We aimed to determine the rate of advanced colorectal neoplasia (aCRN), defined as high-grade dysplasia and/or colorectal cancer, following a diagnosis of indefinite dysplasia or LGD in this population. METHODS We performed a retrospective, longitudinal study of 1911 patients with colonic IBD (293 with PSC and 1618 without PSC) who underwent more than 2 surveillance colonoscopies from 2000 through 2015 in The Netherlands or the United States (9265 patient-years of follow-up evaluation). We collected data on clinical and demographic features of patients, as well as data from each surveillance colonoscopy and histologic report. For each surveillance colonoscopy, the severity of active inflammation was documented. The primary outcome was a diagnosis of aCRN during follow-up evaluation. We also investigated factors associated with aCRN in patients with or without a prior diagnosis of indefinite dysplasia or LGD. RESULTS Patients with PSC-IBD had a 2-fold higher risk of developing aCRN than patients with non-PSC IBD. Mean inflammation scores did not differ significantly between patients with PSC-IBD (0.55) vs patients with non-PSC IBD (0.56) (P = .89), nor did proportions of patients with LGD (21% of patients with PSC-IBD vs 18% of patients with non-PSC IBD) differ significantly (P = .37). However, the rate of aCRN following a diagnosis of LGD was significantly higher in patients with PSC-IBD (8.4 per 100 patient-years) than patients with non-PSC IBD (3.0 per 100 patient-years; P = .01). PSC (adjusted hazard ratio [aHR], 2.01; 95% CI, 1.09-3.71), increasing age (aHR 1.03; 95% CI, 1.01-1.05), and active inflammation (aHR, 2.39; 95% CI, 1.63-3.49) were independent risk factors for aCRN. Dysplasia was more often endoscopically invisible in patients with PSC-IBD than in patients with non-PSC IBD. CONCLUSIONS In a longitudinal study of almost 2000 patients with colonic IBD, PSC remained a strong independent risk factor for aCRN. Once LGD is detected, aCRN develops at a higher rate in patients with PSC and is more often endoscopically invisible than in patients with only IBD. Our findings support recommendations for careful annual colonoscopic surveillance for patients with IBD and PSC, and consideration of colectomy once LGD is detected.

Assessment of peri-polyp biopsy specimens of flat mucosa in patients with inflammatory bowel disease. Gastrointest Endosc 2018; 87:1304-1309.

Abstract
BACKGROUND AND AIMS When colon polyps are removed in the setting of inflammatory bowel disease (IBD) involving the large intestine, biopsy sampling of the flat mucosa surrounding such polyps have been recommended, but there are no data to support this practice. METHODS We reviewed endoscopic and pathologic findings in IBD patients who had dysplastic polyps removed and biopsy sampling of the adjacent flat mucosa. We assessed risk for subsequent neoplasia based on the presence or absence of dysplasia in the peri-polyp flat mucosa and based on number and grade of index polypoid lesions. Kaplan-Meier survival analysis was performed. RESULTS Fifty-six IBD patients (68% ulcerative colitis [UC]) underwent 102 colonoscopies, in which 129 dysplastic polyps were resected. Five hundred three biopsy procedures of the surrounding flat mucosa were performed (mean, 3.9 biopsy samples per polyp), of which 16 (3.2%) were dysplastic. Thirty-four patients (21 UC) had follow-up in a median of 1.7 years (range, .02-15) and 147 colonoscopies. The presence of dysplasia in peri-polyp biopsy specimens during index colonoscopy was not associated with risk of developing high-grade dysplasia (HGD) or cancer (Pearson χ2 test = .19). The size and number of dysplastic polyps were not predictive of neoplastic outcomes, but the probability of developing subsequent advanced neoplasia for polypoid low-grade dysplasia was 18%, 29%, and 40% by 1, 3, and 5 years, respectively, and for polypoid HGD was 50%, 60%, and 70% by 1, 3, and 5 years, respectively (hazard ratio, 7.0; standard error, 4.8). CONCLUSIONS In patients with IBD-associated colitis, biopsy sampling of the mucosa adjacent to discrete dysplastic polypoid lesions are low yield and do not predict findings in follow-up examinations. However, the grade of dysplasia of the polyp itself is predictive of subsequent advanced neoplasia.

Abstract
Background The rationale behind this study was to find out the frequency of dysplasia and colorectal cancer (CRC) in young patients with ulcerative colitis (UC) using histopathological examination. This facilitated early detection of dysplasia and CRC by regular endoscopic biopsies and also guided physicians on appropriate surveillance and management, thus improved outcome. Methods It was a prospective cross-sectional study conducted at the Department of Pathology, PIMS, Islamabad. Seventy-six biopsies of already diagnosed cases of UC of young patients aged between 15 and 40 years of either gender were included. Specimens were fixed in 10% buffer formalin, paraffin embedded followed by cutting, slide preparation, and staining with hematoxylin and eosin (H&E) stain, and examined under light microscope. Statistical package for social sciences (SPSS 21) was used for data compilation and analysis. Mean and standard deviation were calculated for quantitative variables. Frequency and percentage were calculated for qualitative variables. Results There were 13 (17.2%) patients who were diagnosed with colorectal dysplasia, 3 (4.0%) with indefinite for dysplasia, 8 (10.5%) with low-grade dysplasia, and 2 (2.6%) with high-grade dysplasia. There were three (3.9%) patients who were diagnosed for colorectal carcinoma, one (1.3%) with grade 1, one (1.3%) with grade 2, and one (1.3%) with grade 3 CRC. Conclusion Routine biopsies can identify dysplastic epithelium, which is an established sign for synchronized carcinoma with ulcerative colitis, and give the rationale for surveillance of the patients.

Abstract
PURPOSE OF REVIEW Patients with long-standing ulcerative colitis have an increased risk for the development of colorectal cancer (CRC). Colitis-related dysplasia appears to confer the greatest risk. Colonoscopic surveillance to detect dysplasia has been advocated by gastrointestinal societies. The aim of surveillance is the reduction of mortality and morbidity of CRC through detection and resection of dysplasia or detecting CRC at an earlier and potentially curable stage. Traditional surveillance has relied on mucosal assessment with targeted biopsy of visible lesions and random biopsy sampling on the premise that dysplasia was not visible at endoscopy. Advances in optical technology permitting increased detection of dysplasia and evidence that most dysplasia is visible has had practice-changing implications. RECENT FINDINGS Emerging evidence favours chromoendoscopy (CE) for dysplasia detection and is gaining wider acceptance through recent international (International Consensus Statement on Surveillance and Management of Dysplasia in Inflammatory Bowel Disease (SCENIC)) recommendations and endorsed by many gastrointestinal societies. Adoption of CE as the gold standard of surveillance has been met with by scepticism, from conflicting data, operational barriers and the need to understand the true impact of increasingly higher dysplasia detection on overall CRC mortality. Valid debate notwithstanding, implementation of a risk stratification protocol that includes CE is an effective approach allowing earlier detection of dysplasia and colorectal neoplasia, determination of surveillance intervals with appropriate allocation of resources and limiting morbidity from CRC and colonoscopy itself. Further prospective data should define the true and long-term impact of dysplasia detection with modern techniques.

Abstract
Colitis-associated cancer is a relatively rare form of cancer with an unclear pathogenesis. Colitis-associated cancer serves as a prototype of inflammation-associated cancers. Advanced colonoscopic techniques are considered standard of care for surveillance in patients with long-standing colitis, especially those with other risk factors, including sclerosing cholangitis and a family history of colorectal cancer. When colitis-associated cancer is diagnosed, the standard operation involves total proctocolectomy. Restorative procedures and surveillance after colectomy require special considerations. In these contexts, new 3-dimensional human models may be used to usher in personalized medicine.

Abstract
BACKGROUND AND AIMS There is uncertainty regarding the optimal management of endoscopically invisible (flat) low-grade dysplasia in ulcerative colitis. Such a finding does not currently provide an automatic indication for colectomy; however, a recommendation of surveillance instead of surgery is controversial. The aim of this study was to determine the clinical and cost-effectiveness of colonoscopic surveillance versus colectomy for endoscopically invisible low-grade dysplasia of the colon in ulcerative colitis. METHODS A Markov model was used to evaluate the costs and health outcomes of surveillance and surgery over a 20-year timeframe. Outcomes evaluated were life years gained and quality-adjusted life years (QALYs). Cohorts of patients aged 25 to 75 were modeled, including estimates from a validated surgical risk calculator and considering none, 1, or both of 2 key comorbidities: heart failure and obstructive airway disease. RESULTS Surveillance is associated with more life years and QALYs compared with surgery from age 61 for those with no comorbidities, age 51 for those with 1 comorbidity and age 25 for those with 2 comorbidities. At the current United Kingdom National Institute for Health and Care Excellence threshold of $25,800 per QALY, ongoing surveillance was cost-effective at age 65 in those without comorbidities and at age 60 in those with either 1 or more comorbidities. CONCLUSIONS Surveillance can be recommended from age 65 for those with no comorbidities; however, in younger patients with typical postsurgical quality of life, colectomy may be more effective clinically and more cost-effective. The results were sensitive to the colorectal cancer incidence rate in patients under surveillance and to quality of life after surgery.

Abstract
BACKGROUND AND AIMS Long-standing ulcerative colitis is an established risk factor for colorectal neoplasia. A number of observational studies have suggested that evidence of mucosal inflammation (endoscopic or histologic) is associated with a greater risk for colorectal neoplasia than is mucosal healing. Our goal was to systematically analyze the risk of colorectal neoplasia in patients with ulcerative colitis who have ongoing mucosal inflammation to better inform surveillance strategies. METHODS We performed a systematic review and meta-analysis of the effect of endoscopic and/or histologic inflammation on the risk of colorectal neoplasia in cohort and case-control studies. Sensitivity analyses for study setting and case definition were performed. RESULTS Six studies met the inclusion criteria, incorporating outcomes in 1443 patients. No study used a single validated measure for mucosal inflammation. The pooled odds ratio for colorectal neoplasia was 3.5 (95% confidence interval [CI], 2.6-4.8; P < .001) in those with any mucosal inflammation and 2.6 (95% CI, 1.5-4.5; P = .01) in those with histologic inflammation, when compared with those with mucosal healing. The overall quality of the studies was good. CONCLUSION The presence of objective evidence of mucosal inflammation during follow-up in patients with ulcerative colitis is associated with a greater risk of subsequent colorectal neoplasia than in those with mucosal healing. This risk factor should be considered in guidelines on surveillance intervals for these patients.

Abstract
Long-standing intestinal inflammation in patients with inflammatory bowel disease (IBD) induces dysplastic change in the intestinal mucosa and increases the risk of subsequent colorectal cancer. The evolving endoscopic techniques and technologies, including dye spraying methods and high-definition images, have been replacing random biopsies and have been revealed as more practical and efficient for detection of dysplasia in IBD patients. In addition, they have potential usefulness in detailed characterization of lesions and in the assessment of endoscopic resectability. Most dysplastic lesions without an unclear margin, definite ulceration, non-lifting sign, and high index of malignant change with suspicion for lymph node or distant metastases can be removed endoscopically. However, endoscopic resection of dysplasia in chronic IBD patients is usually difficult because it is often complicated by submucosal fibrosis. In patients with dysplasias that demonstrate submucosa fibrosis or a large size (≥20 mm), endoscopic submucosal dissection (ESD) or ESD with snaring (simplified or hybrid ESD) is an alternative option and may avoid a colectomy. However, a standardized endoscopic therapeutic approach for dysplasia in IBD has not been established yet, and dedicated specialized endoscopists with interest in IBD are needed to fully investigate recent emerging techniques and technologies.

Abstract
Inflammatory bowel disease (IBD) patients are at an increased risk of developing colorectal cancer (CRC), a devastating complication of which intestinal dysplasia is the precursor. Considerable progress has been made to determine CRC risk in IBD, identification & management of dysplasia and preventative methods. Traditionally, surveillance colonoscopies with random colonic biopsies was used. However recent data suggests that chromoendoscopy is a better method of surveillance. Using 5-aminosalicylic acid agents primarily for chemoprevention is an ongoing debate however, when prescribed along with other strategies to control inflammation, their use is considered of benefit. This review presents current understanding of risk factors of neoplasia focusing on dysplasia and preventive strategies. Areas covered: PubMed search was done using key words to assess current evidence. Along with genetics, risk factors, strategies that modify the risk of dysplasia, and CRC in IBD are discussed in detail. Expert commentary: The role of our strategies in modifying CRC risk needs further assessment. Future research should aim to fill knowledge gaps such as high quality evidence for Chromoendoscopy and development of molecular markers for dysplasia detection. Our ultimate goal would be to eliminate CRC and is possible by better understanding of key pathogenic mechanisms in IBD.

Abstract
Colitis-associated cancer (CAC) represents a concrete risk of morbidity and mortality in patients with long lasting inflammatory bowel diseases. Surveillance colonoscopy is a rapidly evolving research field with profound changes from the traditional approach based on scheduled controls and random biopsy protocols. Areas covered: A literature search was performed using PubMed/Embase to review the latest evidence supporting the need for surveillance colonoscopy. By focusing on the most promising recent advances in this field, we provide a state-of-the-art overview of the current gold standards for the diagnosis and management of colitis-associated dysplasia. Expert commentary: Evidence-based and emerging data have questioned the efficacy and effectiveness of both standard surveillance colonoscopy and random biopsy protocols. The latest guidelines endorse early initiation of surveillance programs, risk-profiling assessment of colonoscopy intervals and standardized use of advanced imaging modalities to detect early dysplasia. Current trends clearly reveal increased attention to direct visualization and endoscopic management of visible dysplastic lesions, even in patients with longstanding colitis. Emerging technological advances in gastrointestinal endoscopy are expected to change the endoscopic surveillance protocols in the near future.

Abstract
BACKGROUND & AIMS Little is known about outcomes of patients with ulcerative colitis with low-grade dysplasia (UC-LGD). We estimated the incidence of and risk factors for progression to colorectal cancer (CRC) in cohorts of patients with UC-LGD who underwent surveillance (surveillance cohort), and the prevalence of dysplasia-related findings among patients who underwent colectomy for UC-LGD (surgical cohort). METHODS We performed a systematic literature review through June 1, 2016, to identify cohort studies of adults with UC-LGD. We estimated pooled incidence rates of CRC and risk factors associated with dysplasia progression in surveillance cohorts, and prevalence of synchronous advanced neoplasia (CRC and/or high-grade dysplasia) in surgical cohorts. RESULTS In 14 surveillance cohort studies of 671 patients with UC-LGD (52 developed CRC), the pooled annual incidence of CRC was 0.8% (95% confidence interval [CI], 0.4-1.3); the pooled annual incidence of advanced neoplasia was 1.8% (95% CI, 0.9-2.7). Risk of CRC was higher when LGD was diagnosed by expert gastrointestinal pathologist (1.5%) than by community pathologists (0.2%). Factors significantly associated with dysplasia progression were concomitant primary sclerosing cholangitis (odds ratio [OR], 3.4; 95% CI, 1.5-7.8), invisible dysplasia (vs visible dysplasia; OR, 1.9; 95% CI, 1.0-3.4), distal location (vs proximal location; OR, 2.0; 95% CI, 1.1-3.7), and multifocal dysplasia (vs unifocal dysplasia; OR, 3.5; 95% CI, 1.5-8.5). In 12 surgical cohort studies of 450 patients who underwent colectomy for UC-LGD, 34 patients had synchronous CRC (pooled prevalence, 17%; 95% CI, 8-33). CONCLUSION In a systematic review of the literature, we found that among patients with UC-LGD under surveillance, the annual incidence of progression to CRC was 0.8%; differences in rates of LGD diagnosis varied with pathologists' level of expertise. Concomitant primary sclerosing cholangitis, invisible dysplasia, distal location, and multifocal LGD are high-risk features associated with dysplasia progression.

Abstract
BACKGROUND AND AIMS Ulcerative colitis increases the risk of developing colorectal cancer. Colonoscopic surveillance is recommended although there are no randomized trials evaluating the efficacy of such a strategy. This study is an update of earlier studies from an ongoing colonoscopic surveillance program. MATERIAL AND METHODS All patients with ulcerative colitis were invited to the surveillance program that started in 1977 at Örnsköldsvik Hospital, located in the northern part of Sweden. Five principal endoscopists performed the colonoscopies and harvested mucosal sampling for histopathological evaluation. Some 323 patients from the defined catchment area were studied from 1977 to 2014. At the end of the study period, 130 patients, including those operated on, had had total colitis for more than 10 years. RESULTS In total, 1481 colonoscopies were performed on 323 patients during the study period without any major complications. In all, 10 cases of colorectal cancer were diagnosed in 9 patients, of whom 1 died from colorectal cancer. The cumulative incidence of colorectal cancer was 1.4% at 10 years, 2.0% at 20 years, 3.0% at 30 years, and 9.4% at 40 years of disease duration, respectively. The standardized colorectal cancer incidence ratio was 3.01 (95% confidence interval: 1.42-5.91). Major surgery was performed on 65 patients; for 20 of these, the indication for surgery was dysplasia or colorectal cancer. Panproctocolectomy was performed in 43 patients. CONCLUSION This study supports that colonoscopic surveillance is a safe and effective long-term measure to detect dysplasia and progression to cancer. The low numbers of colorectal cancer-related deaths in our study suggest that early detection of neoplasia and adequate surgical intervention within a surveillance program may reduce colorectal cancer mortality in ulcerative colitis patients.

Abstract
AIM Surgery aims to prevent cancer-related morbidity for patients with ulcerative colitis (UC) associated dysplasia. The literature varies widely regarding the likelihood of dysplastic progression to higher grades of dysplasia or cancer. The aim of this study was to characterize the likelihood of the development of colorectal cancer (CRC) of patients with UC-associated dysplasia who chose to defer surgery. METHOD A retrospective review was carried out of patients undergoing surgery for UC at the Mayo Clinic, who were diagnosed to have dysplasia between August 1993 and July 2012. The relationships between grade of dysplasia, time to surgery and the detection of unsuspected carcinoma were investigated. RESULTS In all, 175 patients underwent surgery at a median of 4.9 (interquartile range 2.5-8.9) months after a diagnosis of dysplasia. Their median age was 52 (interquartile range 43-59) years. An initial diagnosis of indeterminate dysplasia was not associated with CRC [0/23; 17.7 (8.1-29.6) months]. Thirty-six patients who had an initial diagnosis of dysplasia progressed from indeterminate to low-grade dysplasia [24.2 (11.0-30.4) months]. Low-grade dysplasia was associated with a 2% (1/56; T2N0M0) risk of CRC when present in random surveillance biopsies and a 3% (2/61; T1N0M0, T4N0M0) risk if detected in endoscopically visible lesions [7.4 (5.2-33.3) months]. Eighteen patients progressed from indeterminate to high-grade dysplasia [19.1 (9.2-133.9) months]. Seventeen patients progressed from low to high-grade dysplasia [11.0 (5.8-30.1) months]. None of the patients with high-grade dysplasia (0/35) progressed to CRC [4.5 (1.7-9.9) months]. CONCLUSION Dysplasia was associated with a low incidence of node negative CRC if surgery was deferred for up to 5 years. These findings may help inform the decision-making process for asymptomatic patients who are having to decide between intensive surveillance or surgery for UC-associated dysplasia.

Abstract
Inflammatory bowel disease (IBD) is an important etiologic factor in the development of colorectal cancer (CRC). The risk of CRC begins to increase 8 or 10 years after the diagnosis of IBD. This type of cancer is called colitis-associated CRC (CA-CRC). The molecular pathogenesis of inflammatory epithelium might play a critical role in the development of CA-CRC. Genetic alterations detected in CA-CRC such as genetic mutations, microsatellite instability, and DNA hypermethylation are also recognized in sporadic CRC; however, there are differences in the timing and frequency of molecular events between CA-CRC and sporadic CRC. Interaction between gene-environmental factors, including inflammation, lifestyle, psychological stress, and prior appendectomy, might be associated with the etiopathology of IBD. The mucosal inflammatory mediators, such as oxidant stress, free radicals, and chemokines, may cause the genetic alterations. Understanding the molecular mechanisms of CA-CRC might be important to develop clinical efficacies for patients with IBD. This review discusses the molecular characteristics of CA-CRC, especially ulcerative colitis-associated CRC, including clinical features, signaling pathways, and interactions between genetic alterations and environment involved in inflammatory carcinogenesis.

Abstract
Background and aims: We previously demonstrated a significant colorectal neoplasia risk in inflammatory bowel disease (IBD) patients with mucosal changes indefinite for dysplasia (IND) and the potential diagnostic utility of p53 and cytokeratin 7 immunohistochemistry in IBD-associated neoplasia. The primary aim of this exploratory study was to determine the predictive value of the two markers for neoplasia risk in the IBD-IND population. Methods: We identified 44 eligible cases with IBD and IND in colon biopsy from our pathology database. We semi-quantified the expression of p53 and cytokeratin 7 in the colon biopsies by immunohistochemistry and correlated their expression, demographic information, and clinical features with colorectal neoplasia outcome. Results: The mean age of the cohort was 46.6 ± 15.1 years, with 25 (56.8%) being male. The median follow-up was 101 months (range: 6–247) after IND diagnosis. Among these 44 patients, 11 (25%) progressed to neoplasia (low-grade dysplasia = 6; high-grade dysplasia = 2; cancer 3) at a median follow-up of 66 months (range: 19–145). Univariate analysis demonstrated that age and p53 overexpression were associated with progression to neoplasia. Conclusions: Twenty-five percent of patients with IBD and IND developed colorectal dysplasia or cancer. Overexpression of p53 and age are associated with neoplastic progression.

Abstract
In the last years, an increasing interest has been raised on non-polypoid colorectal tumors (NPT) and in particular on large flat neoplastic lesions beyond 10 mm tending to grow laterally, called laterally spreading tumors (LST). LSTs and large sessile polyps have a greater frequency of high-grade dysplasia and local invasiveness as compared to pedunculated lesions of the same size and usually represent a technical challenge for the endoscopist in terms of either diagnosis and resection. According to the Paris classification, NPTs are distinguished in slightly elevated (0-IIa, less than 2.5 mm), flat (0-IIb) or slightly depressed (0-IIc). NPTs are usually flat or slightly elevated and tend to spread laterally while in case of depressed lesions, cell proliferation growth progresses in depth in the colonic wall, thus leading to an increased risk of submucosal invasion (SMI) even for smaller neoplasms. NPTs may be frequently missed by inexperienced endoscopists, thus a careful training and precise assessment of all suspected mucosal areas should be performed. Chromoendoscopy or, if possible, narrow-band imaging technique should be considered for the estimation of SMI risk of NPTs, and the characterization of pit pattern and vascular pattern may be useful to predict the risk of SMI and, therefore, to guide the therapeutic decision. Lesions suitable to endoscopic resection are those confined to the mucosa (or superficial layer of submucosa in selected cases) whereas deeper invasion makes endoscopic therapy infeasible. Endoscopic mucosal resection (EMR, piecemeal for LSTs > 20 mm, en bloc for smaller neoplasms) remains the first-line therapy for NPTs, whereas endoscopic submucosal dissection in high-volume centers or surgery should be considered for large LSTs for which en bloc resection is mandatory and cannot be achieved by means of EMR. After piecemeal EMR, follow-up colonoscopy should be performed at 3 mo to assess resection completeness. In case of en bloc resection, surveillance colonoscopy should be scheduled at 3 years for adenomatous lesions ≥ 1 cm, or in presence of villous features or high-grade dysplasia patients (regardless of the size), while less intensive surveillance (colonoscopy at 5-10 years) is needed in case of single (or two) NPT < 1 cm presenting tubular features or low-grade dysplasia at histology.

Abstract
Dysplasia that develops in the setting of inflammatory bowel disease precedes colorectal cancer (CRC). The category of "indefinite for dysplasia (IND)" is used often in equivocal cases, but its clinical significance remains unclear. Flow cytometric analysis of DNA content (aneuploidy) has shown some promise in stratifying patients into low or high risk of CRC, but there are few reports that have specifically evaluated the outcome of IND. As such, we analyzed a series of 84 IND inflammatory bowel disease patients seen at the University of Washington and Harborview Medical Centers from 2003 to 2013 to determine the outcome of IND. Hospital electronic medical records were further reviewed to correlate outcome with the type of lesion (flat versus polypoid), primary sclerosing cholangitis, active inflammation in the area of IND, and DNA flow cytometric data. The data show that 13% of IND cases were found to have low-grade dysplasia, whereas only 2% of IND cases showed advanced neoplasia (high-grade dysplasia or CRC) after a mean follow-up of 28 months. The risk of neoplasia was not significantly associated with the type of lesion (P = .94 from log-rank test), primary sclerosing cholangitis (P = .94), or active inflammation (P = .41) in this cohort. However, the finding of DNA aneuploidy at baseline IND was predictive of subsequent detection of neoplasia (P = .037). IND patients with abnormal DNA flow cytometric results may warrant more careful follow-up, but conversely, IND in the setting of normal DNA content may require less frequent surveillance colonoscopy.

Abstract
The incidence of dysplasia and colorectal cancer in patients with long-standing colitis seems to be decreasing and controversy surrounds our detection and management strategies. Dysplasia is rarer, flatter, and smaller than in previous decades. Current surveillance guidelines, onerous in terms of colonoscopic workload and an emphasis on random biopsies, have yet to be shown to prevent colon cancers and colon cancer death in these patients. The evidence base for adjunct techniques such as chromoendoscopy is strong but adoption has been slow. We need to better risk-stratify patients with colitis and direct diminishing medical resources accordingly. Modulating dysplasia and cancer risk will involve optimizing medical therapies and focusing our colonoscopic efforts on those who will most likely benefit.

Abstract
Background and aim: Crohn’s colitis (CC) is associated with primary sclerosing cholangitis (PSC). However the risk of colon cancer or dysplasia in CC and PSC is unclear. Our aim was to study the risk of colon neoplasia in CC in patients with and without PSC. Methods: This is a nested, case-control cohort study of all patients diagnosed with concurrent CC and PSC, seen at the Cleveland Clinic between 1985 and 2012. Forty-three patients with both CC and PSC were compared with a random sample of 159 CC controls without PSC during the same period. Results: Seven (16.3%) of 43 CC patients with PSC developed colon cancer or dysplasia, compared with 22 (13.8%) of 159 controls (P = 0.98). Of seven colon neoplasia cases in the PSC group, 100% occurred proximal to the splenic flexure, compared with 50% (11/22) cases of colon neoplasia in controls occurring in the proximal colon (P = 0.001). Based on Cox regression analysis, male gender independently increased the risk of neoplasia [hazard ratio (HR) = 2.68; 95% confidence interval (CI) 1.30–5.54; P = 0.008], as did age at CC diagnosis (HR = 1.29; 95% CI 1.14–1.47; P < 0.001), while the use of azathioprine/6-mercaptopurine was protective (HR = 0.30; 95% CI 0.13–0.70; P = 0.005). The presence of PSC did not increase the risk for colon neoplasia (HR = 0.45; 95% CI 0.18–1.13; P = 0.09). Conclusions: CC patients with PSC appear not to be at increased risk of developing colon neoplasia. Among patients in our cohort with colon neoplasia and concurrent PSC, the neoplasia occurred in the proximal colon in all cases.

Risk for colorectal neoplasia in patients with inflammatory bowel disease and mucosa indefinite for dysplasia. Inflamm Bowel Dis 2015; 21:378-84.

Abstract
BACKGROUND The management of colonic epithelial changes indefinite for dysplasia (IND) in patients with inflammatory bowel disease (IBD) remains controversial because of a paucity of published outcome data. METHODS We analyzed data from 93 patients with IBD who were IND and 52 IBD patients without dysplasia (controls) from the Department of Anatomic Pathology database at the Cleveland Clinic from 1989 to 2004. Pathology reports, histologic slides, clinical features, and outcomes were reviewed. RESULTS Twenty-two patients (23.7%) had surgical resections within 6 months of the IND assignment; of these, 6 had dysplasia (27.3%; 1 low-grade dysplasia and 5 high-grade dysplasia [HGD]). The remaining 71 patients received regular colonoscopy examinations for a mean period of 98.6 months; 18 patients developed dysplasia or carcinoma (25.2%; 10 low-grade dysplasia, 5 HGD, and 3 colorectal cancer). There was a mean interval of 53.9 months between an IND assignment and identification of dysplasia or carcinoma. Histology review of 59 cases revealed 3.2 cases per 100 person-years for neoplasia (low-grade dysplasia, HGD, or colorectal cancer) and 1.5 cases per 100 person-years for advanced neoplasia (HGD or colorectal cancer); these values were higher than those for controls (1.9 cases per 100 person-years for neoplasia and 0.7 cases per 100 person-years for advance neoplasia; P = 0.1 and P = 0.2, respectively, for IND versus controls). Patients aged more than 44 years when they were found to be IND were more likely than younger patients to develop neoplasia (hazard ratio, 6.7; P = 0.01). CONCLUSIONS Patients with IBD and IND are at significant risk for colorectal dysplasia and cancer. These patients should be closely followed.

Abstract
The association between ulcerative colitis (UC) and colorectal cancer (CRC) has been acknowledged. One of the most serious and life threatening consequences of UC is the development of CRC (UC-CRC). UC-CRC patients are younger, more frequently have multiple cancerous lesions, and histologically show mucinous or signet ring cell carcinomas. The risk of CRC begins to increase 8 or 10 years after the diagnosis of UC. Risk factors for CRC with UC patients include young age at diagnosis, longer duration, greater anatomical extent of colonic involvement, the degree of inflammation, family history of CRC, and presence of primary sclerosing cholangitis. CRC on the ground of UC develop from non-dysplastic mucosa to indefinite dysplasia, low-grade dysplasia, high-grade dysplasia and finally to invasive adenocarcinoma. Colonoscopy surveillance programs are recommended to reduce the risk of CRC and mortality in UC. Genetic alterations might play a role in the development of UC-CRC. 5-aminosalicylates might represent a favorable therapeutic option for chemoprevention of CRC.

Abstract
Endoscopic submucosal dissection is a minimally invasive endoscopic technique for the removal of gastrointestinal tumours that is increasingly being used for colonic neoplasms to spare resection of colon in selected patients. Colonic endoscopic submucosal dissection is technically challenging and was initially pioneered in Japan but increasingly used in selected western centres. Its use in Canada is currently limited, and the authors review the challenges and opportunities, in addition to the unique training infrastructure required to practice the procedure under supervision. Specific tools are required to perform endoscopic submucosal dissection and meticulous attention to detail is essential. The authors provide a combined Japanese and Canadian perspective to this technique, and discuss training and performance of endoscopic submucosal dissection as well as potential indications.
