Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Studying samples of blood and tissue in the laboratory from patients with cancer, patients with colorectal polyps and from patients without polyps may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. PURPOSE: This research study is looking at biomarkers in blood and tissue samples from patients with colorectal cancer or colorectal polyps and from patients without polyps (healthy volunteers).

Colorectal cancer kills forty five people in France every day. Epidemiological studies suggest that two cases out of three could be prevented and show that processed meat intake is a consistent risk factor. The aim of this study is to understand how meat promotes cancer, to find protective strategies, and to make compelling dietary recommendations.

RATIONALE: Learning how often patients experience nausea and vomiting after receiving anti-vomiting medicine and chemotherapy for colorectal cancer may help doctors plan better treatment and improve patients' quality of life. PURPOSE: This clinical trial is studying delayed nausea and vomiting in patients with colorectal cancer receiving standard anti-vomiting medicine during the first course of chemotherapy.

Epigenomics is developing a colon cancer screening assay based on differential methylation of specific CpG sites for the detection of early stage disease. A genome-wide methylation analysis and oligonucleotide array study using DNA from various stages of colon cancer and normal tissue have been completed to obtain candidate CpG markers. Based on results obtained in the above studies, Epigenomics has moved to the final stages of feasibility with a specific, highly sensitive real-time marker assay that is able to detect colon cancer DNA in blood plasma.

The purpose of this study is to evaluate a decision aid (written information booklet designed to facilitate informed decision making) to help people aged 55-64 years, with low levels of education and literacy, make an informed choice about bowel cancer screening, using faecal occult blood testing.

The purpose of this study is to determine whether direct mailings to patients with positive fecal occult blood tests can increase rates of performing followup colonoscopy.

RATIONALE: Genetic studies may help in understanding the genetic processes that cause some types of cancer. PURPOSE: Genetic trial to study certain genes of patients who have stage II or stage III colon cancer.

5-Fuorouracil (5-Fu) remains one of the most effective and most commonly used drugs to treat colorectal cancer. Mucositis is a major complication that occurs in approximately 80% of patients receiving 5-FU and results in abdominal bloating as well as vomiting and diarrhea. oral mucositis (OM) are often very painful and compromise nutrition and oral hygiene as well as increase risk for local and systemic infection. OM is characterized by an intense inflammatory reaction on the mucosa lamina propria cells, which results in activation of the transcription factor NF-kB. The activation of NF-kB leads to transcription of genes involved in the synthesis of pro-inflammatory cytokines, such as IL-1β, IL-6 and TNF-α. Agents known to attenuate the expression of cytokines have demonstrated efficacy in the prevention of experimental mucositis. The use of atorvastatin were associated with reduced production of TNF-α and IL-1β and decreased neutrophil infiltration evidenced by histopathological analysis and Myeloperoxidase (MPO) activity. In addition, atorvastatin also reduced oxidative stress and induced an increase in non-protein sulfhydryl groups showing anti-inflammatory and immunomodulatory action.

Our aim will be to evaluate the efficacy of perioperative Duloxetine in decreasing acute postoperative pain after laparoscopic colorectal cancer surgery and its role in reducing postoperative morphine requirements

The goal of distal attachment devices is to enhance an endoscopist's adenoma detection rate (ADR). A device called EndoCuff Vision (ECV) has been introduced that employs a single row of flexible arms to evert colonic folds, thus optimizing mucosal visualization and enhancing ADR. ECV has been shown to be efficacious in improving ADR within the context of randomized trials. However, no 'real-world' studies have been published assessing the effectiveness of ECV in non-trial settings. The primary objective of this study is to assess the effect of ECV use on ADR in a routine screening-related population.
