There is a relative increase in the risk of colon cancer in patients with inflammatory bowel disease (IBD) affecting the colon, and endoscopic surveillance is advocated to mitigate this risk. The current standard practice is to survey this high-risk patient population using colonoscopy. Chromoendoscopy with targeted biopsies has emerged as the colonoscopy modality recommended by the major societies to optimize dysplasia detection. Studies over the past year support the improved yield from targeted as compared to random biopsies and improved dysplasia detection from chromoendoscopy as compared to white light endoscopy...

Colonic inflammation seen in inflammatory bowel disease (IBD) predisposes to the development of colorectal adenocarcinoma. In contrast, colorectal neuroendocrine carcinomas (NECs) have rarely been reported in the setting of IBD, and no definitive relationship between these tumours and IBD has been established. Dysplasia from chronic inflammation leading to neuroendocrine cell differentiation may be responsible for NEC development, though this finding has not been seen consistently. We present a case of large-cell neuroendocrine carcinoma of the sigmoid colon in a 65-year-old woman with long-standing ulcerative colitis...

Receptive anal intercourse and its association with sexually transmitted infections and human papillomavirus-related anal dysplasia has been well studied in various at-risk groups including men who have sex with men. However, the relationship between receptive anal intercourse and its potential complications in patients with inflammatory bowel disease is not fully understood. This narrative review discusses sexually transmitted infections and anal dysplasia in patients with inflammatory bowel disease who engage in receptive anal intercourse and the lack of evidence-based data to guide clinical practice...

Despite significant therapeutic progress in recent years, inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis, remains a challenge regarding its pathogenesis and long-term complications. New concepts have emerged in the management of this disease, such as the "treat-to-target" concept, in which mucosal healing plays a key role in the evolution of IBD, the risk of recurrence and the need for surgery. Endoscopy is essential for the assessment of mucosal inflammation and plays a pivotal role in the analysis of mucosal healing in patients with IBD...

A 68-year-old woman, with a 75-pack-year smoking history and a history of chronic excess alcohol intake, presented with a 5-week history of worsening perianal pain and ulceration. She recently had an inpatient admission with back pain and urinary tract infection during which she developed diarrhea and fecal incontinence. Initially, the perianal ulceration was diagnosed as severe irritant contact dermatitis and treated with barrier creams and topical clobetasone 17-butyrate 0.05% weight for weight, oxytetracycline 3...

BACKGROUND & AIMS: Inflammatory bowel disease (IBD) may increase risk of small bowel cancer (SBC). However, little is known of the characteristics and features of IBD-SBC, due to a low number of cases worldwide. We performed a population-based study of IBD and SBC to calculate risk and increase our understanding of clinical characteristics and histopathological and molecular features. METHODS: The study population consisted of all individuals aged 16 years or older living in Denmark during 1978-2010...

Screening for colorectal cancer (CRC) in patients with inflammatory bowel disease (IBD) is recommended by all scientific societies. However, there are differences in the recommendations they make regarding screening and surveillance. We address a series of questions that come up in the daily clinical practice of a physician. The first two questions that are raised are: (1) Who should be offered screening for CRC? and (2) When should the first colonoscopy be performed? The next step is to decide who should undergo endoscopic surveillance and at what intervals they should be performed...

The prevalence of colorectal cancer (CRC) in inflammatory bowel disease (IBD) is estimated at 3.7%. Risk factors for CRC include more severe disease (as reflected by the extent of disease and the duration of poorly controlled disease), family history of CRC, pseudopolyps, primary sclerosing cholangitis, and male sex. In addition, both early and late onset of IBD have been shown to be risk factors in different studies. Most societal guidelines recommend initiation of surveillance colonoscopy at 8 to 10 years after IBD symptom onset, followed by subsequent surveillance in 1- to 2-year intervals...

Chromoendoscopy pertains to image-enhanced endoscopic techniques such as dye-based chromoendoscopy and electronic chromoendoscopy using narrow-band imaging, flexible spectral imaging color enhancement, and i-scan. Dye-based chromoendoscopy has been demonstrated to improve colorectal dysplasia detection in high-risk patients with long-term inflammatory bowel disease, and electronic chromoendoscopy techniques have been shown to improve characterization of diminutive colorectal lesions, allowing for optical diagnosis during a colonoscopy examination...

Non-familial small bowel carcinomas are relatively rare and have a poor prognosis. Two small bowel carcinoma subsets may arise in distinct immune-inflammatory diseases (celiac disease and Crohn's disease) and have been recently suggested to differ in prognosis, celiac disease-associated carcinoma cases showing a better outcome, possibly due to their higher DNA microsatellite instability and tumor-infiltrating T lymphocytes. In this study, we investigated the histological structure (glandular vs diffuse/poorly cohesive, mixed or solid), cell phenotype (intestinal vs gastric/pancreatobiliary duct type) and Wnt signaling activation (β-catenin and/or SOX-9 nuclear expression) in a series of 26 celiac disease-associated small bowel carcinoma, 25 Crohn's disease-associated small bowel carcinoma and 25 sporadic small bowel carcinoma cases, searching for new prognostic parameters...

BACKGROUND: It is unclear whether intensive surveillance protocols have resulted in a decreased incidence of colorectal cancer (CRC) in inflammatory bowel disease (IBD). AIMS: To determine the prevalence and characteristics of IBD associated high-grade dysplasia (HGD) or CRC that was undetected on prior colonoscopy. METHODS: This is a single-center, retrospective study from 1994 to 2013. All participants had a confirmed IBD diagnosis and underwent a colectomy with either HGD or CRC found in the colectomy specimen...

The association between inflammatory bowel disease (IBD) and colorectal cancer (CRC) is being increasingly investigated. HtrA1 overexpression inhibits cell growth and proliferation by influencing apoptosis, invasiveness and migration of tumour cells. In the present study, HtrA1 expression was analysed in 228 colon tissue samples from patients with CRC, adenoma with high-grade dysplasia (AHD), adenoma with low-grade dysplasia (ALD), ulcerative colitis of >10 year duration (UCL), ulcerative colitis of <5 year duration (UCS) and colonic diverticulitis (D), and was compared with its expression in normal colon tissues (NCTs) collected 5 cm from the CRC lesion and in healthy colon mucosa (HC), to establish whether HtrA1 can serve as a biomarker for these conditions...

BACKGROUND: Long-standing ulcerative colitis (UC) leading to colorectal cancer (CRC) is one of the most serious and life-threatening consequences acknowledged globally. Ulcerative colitis-associated colorectal carcinogenesis showed distinct molecular alterations when compared with sporadic colorectal carcinoma. METHODS: Targeted sequencing of 409 genes in tissue samples of 18 long-standing UC subjects at high risk of colorectal carcinoma (UCHR) was performed to identify somatic driver mutations, which may be involved in the molecular changes during the transformation of non-dysplastic mucosa to high-grade dysplasia...

Inflammatory bowel disease is associated with an increased risk of dysplasia and cancer. Improvements in medical management and endoscopic surveillance have reduced these risks. Patients can develop cancer even in the absence of dysplasia or with indefinite or low-grade dysplasia. Most guidelines recommend starting surveillance colonoscopy 6 to 10 years after initial diagnosis with interval surveillance afterward every 1 to 5 years depending on risk and/or individual characteristics. Most patients should undergo total proctocolectomy with end ileostomy or reconstruction with ileal pouch anal anastomosis because segmental and subtotal resections carry a higher risk of metachronous cancers...

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...

HuR is an RNA-binding protein implicated in immune homeostasis and various cancers, including colorectal cancer. HuR binding to AU-rich elements within the 3' untranslated region of mRNAs encoding oncogenes, growth factors, and various cytokines leads message stability and translation. In this study, we evaluated HuR as a small-molecule target for preventing colorectal cancer in high-risk groups such as those with familial adenomatosis polyposis (FAP) or inflammatory bowel disease (IBD). In human specimens, levels of cytoplasmic HuR were increased in colonic epithelial cells from patients with IBD, IBD-cancer, FAP-adenoma, and colorectal cancer, but not in patients with IBD-dysplasia...

Background and Aims: The extent of lymph node harvesting during surgery for colorectal neoplasm [dysplasia and/or cancer] complicating inflammatory bowel disease [IBD] is a matter of debate. This study aimed to assess the risk of invasive rectal cancer in patients undergoing ileal pouch-anal anastomosis [IPAA] for colonic neoplasm complicating IBD, and thus to clarify whether a systematic total mesorectal excision [TME] should be systematically performed, or not, in those patients. Methods: From 1998 to 2015, all patients who underwent IPAA for colorectal neoplasm complicating IBD were included...

PURPOSE OF REVIEW: To summarize the literature regarding appropriate endoscopic sampling and surveillance protocols for common inflammatory diseases of the digestive tract. Gastroenterologists increasingly use endoscopy with mucosal biopsy to detect inflammatory diseases, assess response to therapy, and monitor for progression to dysplasia. RECENT FINDINGS: Many diseases show a patchy distribution in the digestive tract and there may be poor correlation between the endoscopic appearance and presence of histologic abnormalities...

Mesenchymal stromal cells (MSCs), first found in bone marrow (BM), are the structural architects of all organs, participating in most biological functions. MSCs possess tissue-specific signatures that allow their discrimination according to their origin and location. Among their multiple functions, MSCs closely interact with immune cells, orchestrating their activity to maintain overall homeostasis. The phenotype of tissue MSCs residing in the bowel overlaps with myofibroblasts, lining the bottom walls of intestinal crypts (pericryptal) or interspersed within intestinal submucosa (intercryptal)...

Pseudopolyps are a well described entity in the literature and even though the exact pathogenesis of their formation is not completely understood, they are considered non-neoplastic lesions originating from the mucosa after repeated periods of inflammation and ulceration associated with excessive healing processes. Their occurrence is less common in Crohn's disease than in ulcerative colitis, and their overall prevalence ranges from 4% to 74%; moreover, they are found more often in colon but have been detected in other parts of the gastrointestinal tract as well...
