Active clinical trials for "Colorectal Neoplasms"

This prospective, multi-center, observational study will assess the safety and efficacy of Avastin (bevacizumab) in daily practice in patients with metastatic colorectal cancer who have received no previous treatment for advanced disease and are receiving Avastin in combination with a standard of care first-line chemotherapy regimen. Data will be collected for 1.5 years or until death.

RATIONALE: A disease management program may be more effective than standard therapy in improving quality of life and controlling symptoms in patients with cancer. PURPOSE: This clinical trial is studying a disease management program to see how well it works compared with usual care in patients with stage III or stage IV lung cancer, stage III or stage IV pancreatic cancer, stage III or stage IV ovarian cancer, or stage III or stage IV colorectal cancer, and their caregivers.

This is a study to determine how much nausea and or vomiting is caused by irinotecan-based chemotherapy in patients with colorectal cancer. Patients with colorectal cancer scheduled to receive their first cycle of an irinotecan-based chemotherapy regimen are eligible. Any chemotherapy agents administered in combination with irinotecan must have low-minimal potential to cause nausea and or vomiting. Examples of acceptable regimens would be irinotecan in combination with infusional fluorouracil and leucovorin (FOLFRI) with or without bevacizumab and irinotecan in combination with cetuximab. Patients who have received prior non-irinotecan-based chemotherapy are eligible providing they experienced no vomiting and no greater than mild nausea with their prior chemotherapy.

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.

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: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research trial is studying matrix metalloproteinases after surgery or radiofrequency ablation in patients with liver metastases from colorectal cancer.

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in the immune system that may help kill cancer cells. PURPOSE: This laboratory study is looking at anticancer immune responses in the peripheral blood of patients with colon cancer.

RATIONALE: Studying samples of blood, urine, and tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients respond to treatment. PURPOSE: This laboratory study is analyzing the DNA in tissue samples from patients with advanced colorectal cancer treated with fluorouracil and oxaliplatin with or without bevacizumab on clinical trial E-3200.
