The development of targeted therapies for KRAS, EGFR and HER2 may increase the range of response in patients with colorectal cancer. Mutation at codons 12 and 13 of the KRAS gene has been shown to be predictive of cetuximab response in colorectal cancer. However, due to the combined effects of multiple oncogenes involved in disease progression of patients with colorectal cancer, it seems to be ...
PURPOSE Recent reports revealed that the kinase domain of the ERBB2 gene is somatically mutated in lung adenocarcinoma, suggesting the mutated ERBB2 gene as an oncogene in human cancers. However, because previous reports focused the mutational search of ERBB2 primarily on lung cancers, the data on ERBB2 mutations in other types of human cancers have been largely unknown. EXPERIMENTAL DESIGN H...
BACKGROUND In separate Women's Health Initiative randomized trials, combined hormone therapy with estrogen plus progestin reduced colorectal cancer incidence but estrogen alone in women with hysterectomy did not. We now analyze features of the colorectal cancers that developed and examine the survival of women following colorectal cancer diagnosis in the latter trial. PARTICIPANTS AND METHODS...
Abstract Background: Colorectal cancer is one of the most common cancers of gastrointestinal tract in Iran and the other parts of the world. Colorectal cancer is the fourth leading cause of cancer death in throughout the world. Almost every year recognizes one million new cases of colorectal cancer that nearly half a million of them die due to this disease. Materials and methods: In this ...
The peripheral benzodiazepine receptor (PBR) is overexpressed in a variety of cancers. In Unio Internationale Contra Cancrum (UICC) III colorectal cancers, a high level of PBR overexpression correlates with poor prognosis. However, little is known about the role of PBR in the development and progression of colorectal cancer. This study addresses the up-regulation of PBR during colorectal carcin...
BACKGROUND Colorectal cancer is the third most common cancer worldwide. Diet has been hypothesized as involved in colorectal cancer etiology, but few studies on the influence of total dietary antioxidant intake on colorectal cancer risk have been performed. METHODS We investigated the association between colorectal cancer risk and the total antioxidant capacity (TAC) of the diet, and also of ...
INTRODUCTION Monitoring cancer trends can help evaluate progress in cancer control while reinforcing prevention activities. This analysis examines long-term trends for selected cancers in Canada using data from national databases. METHODS Annual changes in trends for age-standardized incidence and mortality rates between 1970 and 2007 were examined by sex for 1) all cancers combined, 2) the f...
Although most colorectal cancers are chromosomally unstable, the basis for this instability has not been defined. To determine whether genes shown to cause chromosomal instability in model systems were mutated in colorectal cancers, we identified their human homologues and determined their sequence in a panel of colorectal cancers. We found 19 somatic mutations in five genes representing three ...
Immune checkpoint inhibitors represent revolutionary anti-cancer agents, being rapidly approved in different malignancies and settings. Gastrointestinal (GI) cancers represent a wide variety of tumors with specific characteristics and different responses to various therapeutic alternatives; while some are chemo-sensitive others are chemo-resistant and only respond to more aggressive cytotoxic r...
Colorectal cancer (CRC) is one of the most common cancers, but the mechanisms underlying its initiation and progression are largely unknown. TGIF1 (TGFB induced factor homeobox 1) is a transcriptional corepressor that belongs to the three-amino acid loop extension (TALE) superclass of atypical homeodomains. It has been reported that TGIF1 is highly expressed in mammary cancer and non-small cell...
