OBJECTIVES Evidence suggests a possible role of Fusobacterium nucleatum in colorectal carcinogenesis, especially in right-sided proximal colorectum. Considering a change in bowel contents and microbiome from proximal to distal colorectal segments, we hypothesized that the proportion of colorectal carcinoma enriched with F. nucleatum might gradually increase along the bowel subsites from rectum ...
AIM Extracellular matrix metalloprotease inducer (EMMPRIN) expression was demonstrated in several cancers, but its expression profile in colorectal cancers remains unclear. Epidermal growth factor receptor (EGFR) was reported to regulate EMMPRIN expression in human epithelial cancers. Our purpose was to determine EMMPRIN expression and its relationship with EGFR in colorectal cancers. METHODS...
This study was conducted to determine the use of screening for stomach, liver, colorectal, breast, and cervical cancers, which are included in the Korean National Cancer Screening Programme. In 2011 the National Cancer Centre in Korea conducted a nationwide, population-based, cross-sectional interview survey using multi-stage random sampling. Participants included 4,100 cancer-free men 40 years...
Advances have been made in the adjuvant therapy of colorectal cancers. Fluorouracil-based chemotherapy has now been demonstrated to improve long-term disease-free survival rates in patients with resected stage III colon cancer. Combined radiation therapy plus fluorouracil-based chemotherapy has been shown to improve both local control and disease-free survival in patients with stage II and III ...
BRAF mutations occur in 10% to 15% of colorectal cancers and confer adverse outcome in the metastatic setting. Although RAF inhibitors such as vemurafenib (PLX4032) have proven effective in the treatment of BRAF-mutant melanoma, they are surprisingly ineffective in BRAF-mutant colorectal cancers, and the reason for this disparity remains unclear. Compared with BRAF-mutant melanoma cells, BRAF-m...
Background & Aims: Colorectal cancer is one of the most common cancers and one of the leading cause of morbidity and mortality worldwide. Accounting that the risk of colorectal cancer is associated with blood sugar indices as well as the role of CEA in the prognosis of patients with colorectal cancer, this study was fulfilled to determine the relationship between serum level of CEA and HOMA2-IR...
Cancer is the second leading cause of death in the European Union (EU) after diseases of the circulatory system [1]. In 2012, the estimated number of new cases of cancer was 3.4 million (1.8 million occurring in men, 1.6 million occurring in women) and 1.75 million people (976,000 men, 779,000 women) died from cancer in the EU member states [2]. Estimates of incidence in Spain from the most rec...
Biallelic promoter methylation and transcriptional silencing of the MLH1 gene occurs in the majority of sporadic colorectal cancers exhibiting microsatellite instability due to defective DNA mismatch repair. Long-range epigenetic silencing of contiguous genes has been found on chromosome 2q14 in colorectal cancer. We hypothesized that epigenetic silencing of MLH1 could occur on a regional scale...
STUDY OBJECTIVE To investigate the hypothesis that biological aging, as measured by age at diagnosis of some common cancers, is socioeconomically patterned. DESIGN A cross sectional analysis of the association between an area based measure of material deprivation and age at diagnosis of four common cancers (breast, prostate, colorectal, and lung cancers). A further analysis, restricted to bre...
