Accumulating data indicates that certain microRNAs (miRNAs or miRs) are differently expressed in samples of tumors and paired non-tumorous samples taken from the same patients with colorectal tumors. We previously reported to clarify the relationship between the expression of the miRNAs and the endoscopic morphological appearance of the colorectal tumors. In this report, we focused on colorectal adenoma (tubular or tubulovillous adenoma), or tubular early carcinoma or type 2 adenocarcinoma, familial adenomatous polyposis (FAP), ulcerative colitis-associated tumor (UCAT), and sessile serrated adenoma/polyp (SSA/P)...

Approximately 10-20% of inflammatory bowel disease (IBD) cases are diagnosed after 60 years of age. Due to the high prevalence of conditions mimicking IBD at older age - including bowel disease associated with non-steroidal anti-inflammatory drugs, diverticulitis, and microscopic colitis - differential diagnosis of IBD among older adults is frequently delayed. Late-onset IBD is characterized by a predominance of colonic disease and an overall milder disease course; disease progression and new intestinal manifestations are rare...

Background: Cancer and death are the most severe outcomes that affect patients with inflammatory bowel disease (IBD). These outcomes are even more severe if they occur at a young age but are rare, even in the general population. We conducted a systematic review to provide an overview of all reported pediatric (PIBD) patients with severe outcome. Methods: A literature search identified publications that reported development of cancer or fatal outcome in PIBD patients...

Ulcerative colitis (UC) is a chronic, relapsing, inflammatory bowel disease, and patients with long-standing UC are at high risk of developing colorectal cancer as a typical case of the organ-specific chronic inflammation-carcinoma sequence. Interactions between epithelial and stromal cells and alterations in a variety of stromal microenvironments have been demonstrated to have important roles in the carcinogenesis of UC-associated carcinoma. Therefore, the identification of proteins in the inflammatory microenvironment is important not only in the epithelium, however also in the stroma of UC inflammatory foci...

Impaired epithelial regeneration is a crucial pathophysiological feature of ulcerative colitis (UC). Yes-associated protein (YAP1) appears to control cell proliferation and differentiation. In this study, we sought to identify the roles of YAP in intestinal epithelial cell (IEC) self-renewal, regeneration and tumorigenesis. We first observed that YAP was significantly reduced in 62.5% (45/72) of human UC tissues and it was dramatically enhanced during epithelial regeneration in a murine colitis model. Using lentiviral infection, we established a YAP-overexpression (YAPWT ) mouse model...

Ulcerative colitis(UC)is a chronic inflammatorydisease. Since it is known to be a risk factor for colorectal cancer, severe cases, refractorycases, or cases with cancer are often treated with surgery. We report a case of anal canal squamous cell carcinoma(SCC)found 9 years after subtotal colectomy for UC. A 32-year-old man underwent subtotal colectomyand ileorectum anastomosis 9 years ago for fulminant UC. Anemia was detected during treatment with infliximab, which was initiated 2 years ago. Endoscopic findings revealed a type 3 tumor at the anal canal in the anastomotic region, and he presented to our department...

We report the case of a 55-year-old man who successfully underwent resection of a recurrence of ulcerative colitis(UC)- associated colon cancer located in the pancreatic body and left kidney. The patient had undergone an emergency laparotomy (total proctocolectomy with stapled ileal-pouch anal anastomosis)for the treatment of a descending colon cancer with retroperitoneal penetration associated with UC at the age of 50 years. At that time, histological examinations revealed a mucinous carcinoma that was classified as Stage II colon cancer...

BACKGROUND: In ulcerative colitis (UC), the majority of colorectal carcinomas (CRC) arise in the vast colorectal mucosal domain built with mucus-producing goblet cells and columnar cells. Conversely, CRC in UC rarely evolve in the tiny, spotty gut-associated lymphoid tissue (GALT) mucosal domain. Here we review the four reported cases of colonic carcinoma developing in GALT mucosa in UC, searching for possible precursor lesions connected with the evolution of these tumours. MATERIALS AND METHODS: The clinical history, age, gender, endoscopic descriptions, and the pathology (localization, gross and histological descriptions of the luminal surface) of the four UC-GALT carcinomas reported in the literature were reviewed...

A 37-year-old male with long-standing and extensive ulcerative pancolitis developed a rapidly lethal poorly differentiated neuroendocrine carcinoma (NEC) in the sigmoid colon. Prior biopsies obtained from multiple sites of the colon during endoscopic surveillance showed minimal inflammatory changes and no sign of dysplasia. Patients with inflammatory bowel disease (IBD) are at increased risk of colorectal malignancies, and adenocarcinoma is the most common type of colorectal neoplasm associated with ulcerative colitis and Crohn's disease, but other types of epithelial and nonepithelial tumors have also been described in IBD...

OBJECTIVE: To investigate the clinicopathological features and prognosis of colorectal synchronous multiple primary cancer(SMPC). METHODS: From January 2008 to June 2011, 51 patients diagnosed with colorectal SMPC underwent surgery at Department of General Surgery of Peking University First Hospital. Their clinicopathological features, diagnosis, treatment and prognosis were summarized and analyzed. SMPC was diagnosed according to the following criteria: each tumor must have a definite pathologic picture of malignancy; metastasis or recurrence from another colorectal cancer was excluded; tumors must be distinctly separated by at least 5 cm of all intact bowel wall from each other; SMPC has abnormal cells between tumor and normal mucosa and abnormal gland of transitional zone; each cancer is infiltrating carcinoma except the carcinoma in situ; all the cancers are detected at the same time or within 6 months...

Importance: Based on evidence of human papillomavirus (HPV)-induced immune evasion, immunotherapy may be an attractive strategy in cervical cancer. Ipilimumab is a fully humanized monoclonal antibody that blocks cytotoxic T-lymphocyte antigen-4 (CTLA-4), which acts to downregulate the T-cell immune response. Objective: To assess the safety and antitumor activity of ipilimumab in recurrent cervical cancer. Design, Setting, and Participants: A multicenter trial was designed for patients with metastatic cervical cancer (squamous cell carcinoma or adenocarcinoma) with measurable disease and progression after at least 1 line of platinum chemotherapy...

Background: Bile acid diarrhoea (BAD) is a common cause of chronic diarrhoea with a population prevalence of primary BAD around 1%. Previous studies have identified associations with low levels of the ileal hormone fibroblast growth factor 19 (FGF19), obesity and hypertriglyceridaemia. The aim of this study was to identify further associations of BAD. Methods: A cohort of patients with chronic diarrhoea who underwent 75selenohomocholic acid taurate (SeHCAT) testing for BAD was further analysed retrospectively...

Deregulation of the bone morphogenetic protein (BMP) pathway has been documented in colorectal cancer (CRC). Previously, we investigated possible associations between urokinase-type plasminogen activator (uPA) deficiency and expression of extracellular constituents of BMP signaling in a newly developed mouse model of inflammation-driven intestinal neoplasmatogenesis, in which chronic colitis and CRC are induced using dextran sodium sulfate (DSS). In this report, we explored the contribution of intracellular components of Smad-mediated BMP signal transduction using the same model...

Background: Treatment of cancers with programmed cell death protein 1 (PD-1) pathway inhibitors can lead to immune-related adverse events (irAEs), which could be serious and even fetal. Therefore, clinicians should be aware of the characteristics of irAEs associated with the use of such drugs. Methods: The MEDLINE, EMBASE, and Cochrane databases were searched to find potential studies using the following strategies: anti-PD-1/PD-L1 treatment; irAEs; and cancer. R© package Meta was used to pool incidence. Results: Forty-six studies representing 12,808 oncologic patients treated with anti-PD-1/PD-L1 agents were included in the meta-analysis...

BACKGROUND: Tumor suppressor gene p53 expression has been reported in patients with ulcerative colitis (UC). However, the correlation between p53 expression and UC remains controversial. The aim of this meta-analysis was to investigate the association between p53 expression and different pathological types of UC. METHODS: Publications were searched in the PubMed, Embase, EBSCO, Wangfang, and CNKI databases. The overall odds ratios (ORs) and their corresponding 95% confidence intervals (95% CIs) were summarized in this study...

BACKGROUND: While carcinogenesis in Sporadic Colorectal Cancer (SCC) has been thoroughly studied, less is known about Ulcerative Colitis associated Colorectal Cancer (UCC). This study aimed to identify and validate differentially expressed proteins between clinical samples of SCC and UCC to elucidate new insights of UCC/SCC carcinogenesis and progression. RESULTS: Multiplex-fluorescence two-dimensional gel electrophoresis (2-D DIGE) and mass spectrometry identified 67 proteoforms representing 43 distinct proteins...

MTG16 is a member of the myeloid translocation gene (MTG) family of transcriptional corepressors. While MTGs were originally identified in chromosomal translocations in acute myeloid leukemia, recent studies have uncovered a role in intestinal biology. For example, Mtg16-/- mice have increased intestinal proliferation and are more sensitive to intestinal injury in colitis models. MTG16 is also underexpressed in patients with moderate/severe ulcerative colitis. Based on these findings, we postulated that MTG16 might protect against colitis-associated carcinogenesis...

Dysregulation of c-Jun N-terminal kinase (JNK) activation promoted DNA damage response bypass and tumorigenesis in our model of hydrogen peroxide-associated ulcerative colitis (UC) and in patients with quiescent UC (QUC), UC-related dysplasia, and UC-related carcinoma (UC-CRC), thereby adapting to oxidative stress. In the UC model, we have observed features of oncogenic transformation: increased proliferation, undetected DNA damage, and apoptosis resistance. Here, we show that Chk1 was downregulated but activated in the acute and quiescent chronic phases...

AIMS: The majority of the colorectal carcinomas (CRC) arise in a vast mucosal area built with columnar cells and mucus-producing goblet cells. These carcinomas evolve via the conventional (tubular/villous) adenoma-carcinoma pathway, or the serrated adenoma-carcinoma pathway. Much less frequently CRC arise in the gut-associated lymphoid tissue (GALT) mucosal domain via the third pathway of colorectal carcinogenesis. METHODS: All publications on human colorectal GALT carcinomas in the literature were reviewed...
