OBJECTIVE The objective of the present investigation was to explore the expression and significance of Gal-3 and MUC1 in colorectal cancer tissue and tissue adjacent to carcinoma. METHODS In this study we collected colorectal cancer tissues and the tissues adjacent to carcinoma from 45 cases from the Colorectal Cancer Surgery Department of Zhengzhou People's Hospital from December of 2009 to ...
Chemokines are important in the proliferation and metastasis of tumors. CXCL14 is a member of the CXCL chemokine family and exhibits various expression patterns in different types of tumor, even those tumors that occur in the same type of tissue. The expression of CXCL14 and its clinical significance in colorectal carcinoma are unclear. In the present study, the expression levels of CXCL14 in c...
A recent phase II study of patients with metastatic colorectal carcinoma showed that mismatch repair gene status was predictive of clinical response to PD-1-targeting immune checkpoint blockade. Further examination revealed strong correlation between PD-L1 protein expression and microsatellite instability (MSI) in stage IV colorectal carcinoma, suggesting that the amount of PD-L1 protein expres...
tumor angiogenesis shown by microvessel count (mvc) or microvessel density (mvd), is assessed by several studies as prognostic factor in some types of tumors, and also in colorectal carcinoma. this article is payed to correlation between clincopathologic factors and tumor angiogenesis. in this study, immunohistochemical techniques are used for vascular evaluation in specimens from twenty-nine c...
Cancer risk in maintenance hemodialysis patients has been studied epidemiology, which might be influenced by various factors. On the contrary, investigation of cancer-bearing in non-dialysis chronic kidney disease patients has been rarely reported. Recently, we revealed relatively frequent past history of both colorectal cancer and renal cell carcinoma ahead of dialysis introduction and prevale...
Microsatellite instability implying multiple replication errors (RER+ phenotype) characterizes a proportion of colorectal carcinomas, particularly those from patients with the hereditary non-polyposis colorectal carcinoma syndrome. We studied the incidence of microsatellite instability in more than 500 sporadic tumors representing 6 different types of cancer. Apart from colorectal carcinoma [se...
CONTEXT NM23, a metastasis suppressor gene, may be associated with prognosis in patients with colorectal carcinoma. OBJECTIVE To analyze NM23 expression and its association with the presence of lymph node and liver metastases and survival in patients operated on for colorectal carcinoma. METHODS One hundred thirty patients operated on for colorectal carcinoma were investigated. Tissue micro...
PURPOSE If immune cells are involved in tumor surveillance and have a prognostic impact in most primary tumors, little is known about their significance in metastases. Because patients' survival is heterogeneous, even at metastatic stages, we hypothesized that immune cells may be involved in the control of metastases. We therefore characterized the tumor immune microenvironment and its prognost...
Ahigh percentage of colorectal carcinomas overexpress a lot of growth factors and their receptors, including fibroblast growth factor (FGF) and FGF receptor (FGFR). We previously reported that FGFR2 overexpression was associated with distant metastasis and that FGFR2 inhibition suppressed cell growth, migration, and invasion. The FGFR2 splicing isoform FGFR2IIIb is associated with well-differen...
BACKGROUND Several studies have reported inverse associations between folate intake and colorectal carcinoma risk. Few were prospective studies and none evaluated the association between the intake of individual folate vitamers and colorectal carcinoma risk. METHODS The aim of the current study was to investigate the relationship between dietary folate intake and the risk of colorectal carcin...
