BACKGROUND: It is currently uncertain whether non-alcoholic fatty liver disease (NAFLD) is associated with an increased risk of colorectal tumours. We performed a meta-analysis of relevant observational studies to quantify the magnitude of the association between NAFLD and risk of colorectal adenomas and cancer. METHODS: We searched PubMed, Scopus and Web of Science from January 2000 to November 2017 using pre-defined keywords to identify observational studies of asymptomatic adults undergoing screening colonoscopy, in which NAFLD was diagnosed by imaging or histology...

Nrf2 is a transcription factor that regulates cellular stress response and irinotecan-metabolising pathways. Its aberrant activity has been reported in a number of cancers, although relatively few studies have explored a role for Nrf2 in colorectal cancer (CRC). This study assessed the expression of Nrf2 in patient CRC tissues and explored the effect of Nrf2 modulation alone, or in combination with irinotecan, in human (HCT116) and murine (CT26) cell lines in vitro and in an orthotopic syngeneic mouse model utilising bioluminescent imaging...

AIM: Pelvic exenteration surgery remains the only curative option for recurrent rectal cancer. Microscopically involved surgical margins (R1) are associated with a higher risk of local recurrence and decreased survival. Our study aimed to develop a post hoc multidisciplinary case conference review and investigate its potential for identifying areas for improvement. METHOD: Patients who underwent pelvic exenteration surgery for recurrent rectal cancer with R1 resections at a tertiary referral center between April 2014- January 2016 were retrospectively reviewed from a prospectively maintained database...

Acid ceramidase (ASAH1) has been implicated in the progression and chemoresistance in different cancers. Its role in colon cancer biology and response to standard chemotherapy has been poorly addressed so far. Here, we have investigated ASAH1 expression at the protein level in human colon cancer cell lines and tissues from colon cancer patients, and have examined in vitro the possible link between ASAH1 expression and functional activity of p53 protein whose inactivation is associated with the progression from adenoma to malignant tumour in colon cancer...

AIM: In 2014, a national colorectal cancer (CRC) screening program was launched in the Netherlands. It is difficult to assess for the individual CRC patient whether the oncological benefits of surgery will outweigh the morbidity of the procedure, especially in early lesions. This study compares patient and tumour characteristics between screen-detected and non-screen-detected patients. Secondly, we present an overview of treatment options and clinical dilemmas when treating patients with early stage colorectal disease...

PURPOSE: The aim of our study was to compare the characteristics and prognosis between right- and left-sided metastatic colorectal carcinomas. METHODS: Data from 937 patients with stage IV colorectal carcinomas (synchronous distant metastasis) who had a resection of the primary tumour between 1985 and 2014 were analysed. Carcinomas in the caecum to transverse colon were defined as right-sided (n = 250; 26.7%). They were compared to tumours located from the splenic flexure to the rectum categorised as left-sided (n = 687; 73...

Mixed adenoneuroendocrine carcinoma (MANEC) are rare cancers of the gastrointestinal (GI) and pancreatobiliary tract. They are characterized by the presence of a combination of epithelial and neuroendocrine elements, where each component represents at least 30% of the tumour. Review of literature and consolidation of clinicopathological data. Sixty-one cases of colorectal MANEC have been reported in literature and one seen in this centre. The median age of the patients affected was 61.9 ± 12.4 years (20-94 years)...

PURPOSE: MLH1 is a major tumour suppressor gene involved in the pathogenesis of Lynch syndrome and various sporadic cancers. Despite their potential pathogenic importance, genomic regions capable of regulating MLH1 expression over long distances have yet to be identified. EXPERIMENTAL DESIGN: Here we use chromosome conformation capture (3C) to screen a 650-kb region flanking the MLH1 locus to identify interactions between the MLH1 promoter and distal regions in MLH1 expressing and non-expressing cells...

Carcinoembryonic antigen (CEA) is still the most widely used tumour marker for gastrointestinal cancer. CEA was originally thought to be a specific marker for colorectal cancer, but it turned out to be a non-specific marker for further studies. CEA levels can be elevated in breast, lung and liver cancers, among others, including medullary thyroid cancer. The authors report a case of a 73-year-old woman who had a right hemicolectomy for an ascending colon adenocarcinoma and showed a persistent elevation in the CEA marker during follow-up...

The presence of tumor deposits (TD) in colorectal cancer (CRC) is associated with poor prognosis. The 7th edition of TNM subclassified a new nodal stage, N1c, characterized by the presence of TD without any concurrent positive lymph node (LN). It is not clear if the N1c category is equal or not to LN metastasis. We aimed to examine the prevalence, characteristics and prognostic significance of this new subcategory METHODS: Consecutive patients who underwent surgery for CRC in two centers (2011-2014) were analyzed...

BACKGROUND: Indications for surgical resection of non-colorectal, non-neuroendocrine (NCNNE) liver metastases are unclear. This study analysed the influence of response to neoadjuvant chemotherapy and the presence of extrahepatic disease (EHD) on outcomes. METHODS: Patients who underwent hepatic resection for NCNNE liver metastases and who received neoadjuvant chemotherapy at a single centre between 1982 and 2016 were analysed retrospectively. Patients were classified as having no EHD, controlled EHD or non-controlled EHD...

Background: Colorectal cancer (CRC) is both a global and national burden, being the third most common malignancy in men and the second in women, worldwide. The prognosis of CRC is affected by various factors like the histological grade, angiolymphatic invasion, and distant metastases. Metastasis is an intricate process; one of the possible mechanisms is through the interaction of the chemokines CXCL12 and CXCR4. This study aims to reveal the expression patterns of CXCL12 and CXCR4 in CRC...

Biochanin A has been reported to be associated to tumour cell proliferation, apoptosis and drug resistance in hepatocellular carcinoma, prostate cancer, and colorectal cancer, etc, while the relation of biochanin A on osteosarcoma is not clear. Hence, in this study, we examined the effects of biochanin A treatment on osteosarcoma cell lines MG63 and U2OS on proliferation, apoptosis, invasion and migration. We then investigated the involved molecular mechanism and found a time- and dose-dependent inhibition of cell viability in MG63 and U2OS cells with biochanin A treatment...
