Background. Laparoscopy or its combination with endoscopy is the next step for "difficult" polyps. The purpose of the paper was to review the outcomes of the laparoscopic approach to the management of "difficult" colorectal polyps. Materials and methods. From 2006 to 2016, 58 patients who underwent laparoscopic treatment for "difficult" polyps that could not be treated by endoscopy at the National Cancer Institute, Lithuania, were included. The demographic data, the type of surgery, length of post-operative stay, complications, and final pathology were reviewed prospectively...

BACKGROUND & AIMS: Low activity of natural killer (NK) cells has been associated with increased risk of cancer and has been reported in patients with colorectal cancer (CRC). Activity of NK cells can be measured in a small volume of whole blood by a commercially available test. We investigated whether this test could be used to identify patients with CRC, using findings from colonoscopy as a reference standard. METHODS: We performed an open-label, prospective, cross-sectional study of 872 high-risk subjects (more than 40 years old) screened for CRC by colonoscopy at a university hospital in Montreal, Canada from October 2014 through January 2016...

In the era of precision medicine, efforts are needed to identify and tailor screening recommendations among elevated-risk patients. Individuals younger than 50years are an important target population, as they comprise 15% of colorectal (CRC) cases and often present with more advanced disease than their 50+ counterparts. In this large study, 2470 patients ages 25-49 used a tablet-based program that assessed risks, matched risks with screening guidelines, and generated tailored printed guideline-concordant recommendations for patients and their providers...

BACKGROUND: Colorectal cancer in Egypt has a higher incidence in young patients compared to western countries, where the disease is more prevalent in the old age group. This difference has been attributed to higher incidence of hereditary cancers in young Egyptian patients. The aim of this study is to compare the family history criteria and pathology features of tumors in young (<40 years) and old (>40 years) Egyptian patients with adenocarcinoma of the colon and rectum. MATERIALS AND METHODS: This is the analysis of our prospectively collected data on the pathology features of tumors in 313 consecutive patients (133 young, 180 old) with colorectal cancer presenting to the Department of Surgery within an eight-year period...

CX3CR1(+) macrophages in the intestinal lamina propria contribute to gut homeostasis through the immunomodulatory interleukin IL-10, but there is little knowledge on how these cells or the CX3CR1 receptor may affect colorectal carcinogenesis. In this study, we show that CX3CR1-deficient mice fail to resolve gut inflammation despite high production of IL-10 and have increased colitis and adenomatous polyps in chemical and genetic models of colon carcinogenesis. Mechanistically, CX3CL1-mediated engagement of the CX3CR1 receptor induced upregulation of hemoxygenase-1 (HMOX-1), an antioxidant and anti-inflammatory enzyme...

Inflammatory colorectal polyps (ICRPs) in miniature dachshunds (MDs) are a possible novel form of breed-specific canine inflammatory bowel disease (IBD). In this pilot study, we investigated the effects of different Toll like receptor (TLR2, TLR4, TLR5 and TLR9) ligands on pro-inflammatory cytokines (IL-1β, IL-6, IL-8 and TNF-α) gene expression in ex vivo-cultured colorectal samples from four MDs with ICRPs and four healthy MDs. At baseline, no significant difference in the mRNA expression levels of TLRs and pro-inflammatory cytokines was observed between cases and control MDs...

Background and study aims Up to 25 % colorectal adenomas are missed during colonoscopy. The aim of this study was to investigate whether the endocuff could improve polyp detection in an organized bowel cancer screening program (BCSP). Patients and methods This parallel group, single-blinded, randomized controlled trial included patients with positive fecal occult blood test (FOBT) who were attending for BCSP colonoscopy. The primary outcome was the number of polyps per patient. Secondary outcomes included the number of adenomas per patient, adenoma and polyp detection rates, and withdrawal times...

Sessile serrated adenoma/polyps (SSA/Ps) are believed to be the major precursor of serrated pathway-derived colorectal carcinomas. To better characterize the process of progression from SSA/Ps to carcinomas, we analyzed 46 SSA/Ps with dysplasia and 45 SSA/Ps without dysplasia using targeted next-generation sequencing and immunohistochemistry. Among the WNT pathway genes analyzed, protein-truncating mutations of RNF43, APC, and ZNRF3 were identified in 23 (50%), 4 (9%), and 3 (7%) SSA/Ps with dysplasia, respectively...

Regulatory T cells (Tregs), a subset of CD4(+) or CD8(+) T cells, play a pivotal role in regulating immune homeostasis. An increase in Tregs was reported in many tumors to be associated with immune suppression and evasion in cancer patients. Despite the importance of Tregs, the molecular signatures that contributed to their pathophysiological relevance remain poorly understood and controversial. In this study, we explored the gene expression profiles in Tregs derived from patients with colorectal cancer [colorectal carcinoma (CRC), n = 15], colorectal polyps (P, n = 15), and in healthy volunteers (N, n = 15)...

INTRODUCTION AND AIMS: A high quality colonoscopy is key in preventing colorectal cancer, but the risk of colorectal cancer (CRC) exists. The aims of the study were to investigate the incidence, characteristics and predictive factors of post-colonoscopy colorectal cancer (PCCRC). MATERIAL AND METHOD: A retrospective and prospective observational study was designed. A population undergoing colonoscopy between 1-01-1997 and 31-12-2014 was included. We analysed demographic variables, characteristics of the diagnostic colonoscopy of CRC, of the previous ones and the lesions found in them...

Through germline multigene panel testing, we discovered the co-occurrence of Lynch syndrome due to a PMS2 mutation and juvenile polyposis syndrome due to a BMPR1A mutation in a young man with synchronous bladder and colorectal cancers and a family history of colorectal polyps. To our knowledge, this is the first report of an individual having these two hereditary colorectal cancer syndromes. This discovery highlights the benefit of multigene testing over traditional stepwise genetic testing, particularly when a clinical presentation suggests more than one underlying genetic cause...

In a randomized trial of folic acid supplementation for the prevention of colorectal adenomas, we previously found indications of increased risk during later treatment and follow-up. This could have been due to the unmetabolized folic acid or natural reduced and methylated folates to which it is metabolized. In post hoc analyses, we measured methylated folates (mF, the sum of 5-methyl-tetrahydrofolate and 4-alfa-hydroxy-5-methyl-THF) and unmetabolized folic acid (UFA) concentrations in the serum of 924 participants...

The present study aimed to investigate the occurrence and clinical features of cases of multiple primary cancers including colorectal cancer (MPCC). The medical records of patients with colorectal cancer (CRC) who underwent surgery at the Third Xiangya Hospital of Central South University (Changsha, China) between August 2007 and August 2014 were retrospectively analyzed. Patients with MPCCs were identified and mutation analyses were performed on colon specimens. The results revealed that among 1,311 patients with CRC, 59 had MPCC (including 35 cases of ≥1 CRC with ≥1 other cancer type, and 24 cases with multiple CRCs and no other primary cancers)...

It is important to establish effective methods for preventing colorectal cancer because the number of colorectal cancer deaths is increasing. Erythromycin one of the macrolide antibiotics, has been shown to exert pleiotropic effects, such as anti-inflammatory and anti-oxidative effects, on mammalian cells. In the present study, we aimed to evaluate the preventive effects of erythromycin on intestinal carcinogenesis. We first confirmed that erythromycin suppresses the transcriptional activity of nuclear factor-κB and activator protein-1 and the expression of its downstream targets, interleukin-6 and cyclooxygenase-2 in human colon cancer cells...

We aimed to identify the effects of physical activity and body composition on colorectal polyp recurrence in patients with previous colorectal cancer. Three hundred patients were selected randomly from the colorectal cancer survivor cohort of Severance Hospital, Seoul, Korea. Patients reported various recreational physical activities, and received surveillance colonoscopy. Body composition was measured with a body composition analyzer. We compared patients who exercised for at least 1 h/week (active) with those who exercised less frequently or not at all (sedentary)...

BACKGROUND & AIMS: Among patients with large colorectal sessile polyps or laterally spreading lesions, it is important to identify those at risk for submucosal invasive cancer (SMIC). Lesions with overt endoscopic evidence of SMIC are referred for surgery, although those without these features might still contain SMIC that is not visible on endoscopic inspection (covert SMIC). Lesions with a high covert SMIC risk might be better suited for endoscopic submucosal dissection (ESD) than for endoscopic mucosal resection (EMR)...

The WNT signaling pathway is commonly altered during colorectal cancer development. The E3 ubiquitin ligase, RNF43, negatively regulates the WNT signal through increased ubiquitination and subsequent degradation of the Frizzled receptor. RNF43 has recently been reported to harbor frequent truncating frameshift mutations in sporadic microsatellite unstable (MSI) colorectal cancers. This study assesses the relative frequency of RNF43 mutations in hereditary colorectal cancers arising in the setting of Lynch syndrome...
