BACKGROUND Wheat, rye, and barley proteins induce celiac disease, an autoimmune type of gastrointestinal disorder, in genetically susceptible persons. Because the disease may be underdiagnosed, we estimated the prevalence of the disease and tested the hypothesis that assays for serum autoantibodies can be used to detect untreated celiac disease and that(More)
The mRNA expression of 17beta-hydroxysteroid dehydrogenase (17HSD) types 1 and 2 enzymes catalyzing opposite reaction of estrogen metabolism was investigated in colon cancer. Further, the significance of the 17HSD type 2 enzyme as a possible marker of colorectal cancer (CRC) prognosis was studied. In the normal mucosa, 17HSD type 2 mRNA was predominantly(More)
Serrated colorectal carcinomas (CRCs) are morphologically different from conventional CRCs and have been proposed to follow a distinct pathway of CRC formation. Despite studies of single molecular events in this tumor type, the diagnosis of serrated CRC relies on morphology and the putative unique biological character of these tumors has not been(More)
BACKGROUND Inflammation contributes to the pathogenesis of colorectal cancer (CRC), and cytokine levels are altered during colorectal carcinogenesis. METHODS The serum levels of 13 cytokines and their relation to clinical and pathological parameters, and systemic inflammatory response (mGPS, CRP and neutrophil-lymphocyte ratio), were analysed from a(More)
BACKGROUND Toll-like receptor 5 (TLR5) is an immune receptor recognising bacterial flagellin. Activation of TLR5 results in cancer invasion and cytokine release. As certain bacteria have been linked to oral cancer, we wanted to study TLR5 expression in oral tongue squamous cell carcinoma (OTSCC). METHODS Samples from 119 patients with OTSCC were obtained,(More)
BACKGROUND Higher-grade inflammatory infiltrate is a promising marker for better prognosis in colorectal cancer (CRC). However, the knowledge on the interrelationships between different inflammatory cells and classifications is fragmentary. METHODS We analysed the densities of eight types of inflammatory cells in a prospectively recruited group of 117 CRC(More)
AIMS To define the occurrence of KRAS and BRAF mutations, microsatellite instability (MSI), and MGMT and hMLH1 methylation and expression in colorectal serrated adenocarcinoma. METHODS AND RESULTS KRAS codon 12/13 and 59/61 and BRAF V600E mutations, MSI, and MGMT and hMLH1 methylation and expression in 42 serrated adenocarcinomas and 17 serrated adenomas(More)
BACKGROUND Endostatin, a fragment of collagen XVIII, is an endogenous angiogenesis inhibitor with anti-tumour functions. However, elevated circulating endostatin concentrations have been found in several human cancers including colorectal cancer (CRC). METHODS Serum endostatin levels were measured by enzyme-linked immunoassay from a series of 143 patients(More)
Bacteria play a prominent role in immu-noregulation but also can cause local and systemic inflammation. Chronic inflammation as well as certain bacteria such as Helicobacter pylori have been shown to promote oncogenesis. The oral mucosa and gastrointestinal tract are highly colonized by commensal bacteria, helping to regulate the immune system, preventing(More)
Adjuvant therapies are increasingly used in colorectal cancers for the prevention of recurrence. These therapies have side-effects and should, thus, be used only if really beneficial. However, the development of recurrence cannot be predicted reliably at the moment of diagnosis, and targeting of adjuvant therapies is thus based only on the primary stage of(More)
