BACKGROUND p53 gene mutations have been reported in over half of all human cancers and they appear to occur in the early stage of cancer, thus indicating the important role that such mutations may play in the carcinogenesis of the digestive tract. This study investigated the differences in p53 abnormalities between cancers of the upper and lower gastrointestinal tract. MATERIALS AND METHODS T...

Gout is a common inflammatory disease characterized by acute arthritis and hyperuricemia. A number of epidemiological studies have suggested the critical role of gout in carcinogenesis. The aim of this study was to estimate the association between gout and cancer risk by meta-analysis of all relevant studies published to date. A comprehensive literature search in PubMed and Embase databases fro...

Enhancer of zeste 2 (EZH2), a key component of polycomb repressive complex 2 (PRC2), was of great importance in human cancer pathogenesis. Various studies examined the relationship between EZH2 overexpression with the clinical outcome in patients with digestive cancers, but yielded conflicting results. Electronic databases updated to January 2015 were searched to find relevant studies. A meta-a...

BACKGROUND The prognostic value of loss of Krüppel-like factor 4 (KLF4) expression in digestive system cancers has not reached a consensus. This study aimed for a comprehensive investigation of the internal associations between KLF4 expression loss and prognostic implications in patients with digestive system cancers. METHODS We searched for all relevant literatures in the electronic database...

Recent evidence suggests that common functional polymorphisms in the hypoxia inducible factor-1α (HIF-1α) gene may play an important role in the development and progression of digestive cancer, but individually published results are inconclusive. Our meta-analysis is aimed to derive a more precise estimation of the relationships between HIF-1α gene polymorphisms and digestive cancer risk. An ex...

background: gastrointestinal and liver diseases (gild) constitute a noteworthy portion of causes of death and disability in iran. however, data on their prevalence and burden is sparse in iran. the global burden of disease (gbd) study in 2010 has provided invaluable comprehensive data on the burden of gild in iran methods: estimations of death, years of life lost due to premature death (yll), y...

The relationship between the ever-increasing cancer mortality and water pollution is an important public concern in China. This study aimed to explore the association between serious water pollution and increasing digestive cancer mortality in the Huai River Basin (HRB) in China. A series of frequency of serious pollution (FSP) indices including water quality grade (FSPWQG), biochemical oxygen ...

BACKGROUND Several studies have reported the role of the miR-146a rs2910164 G > C polymorphism as a susceptibility factor for several digestive cancers. However, the results have been controversial. Therefore, we conducted the present meta-analysis to obtain the most reliable estimate of the association. METHODS PubMed, Embase and Web of Science databases were searched. Crude odds ratios (ORs...

Objective: To analyse the role of various aspects of the Mediterranean diet in several common epithelial cancers, including digestive and selected non-digestive tract neoplasms. Design: Systematic analysis of data from a series of case–control studies. Setting: Northern Italy, between 1983 and 1998. Subjects: Over 12 000 cases of 20 cancer sites and 10 000 controls. Results: For most epithelial...
