Active clinical trials for "Colorectal Neoplasms"

The purpose of the study is to investigate whether the information about a doctor or possibility to choose doctor's gender included in invitation letter is associated with attendance rate to screening colonoscopy.

The purpose of this study is to determine in a randomized, placebo-controlled, phase II trial if the combination of sulindac and erlotinib causes a significant regression of duodenal and colorectal adenomas in familial adenomatous polyposis (FAP) and attenuated FAP (AFAP) patients.

Primary Objective : Compare the risk of occurrence of Grade3-4 cumulative peripheral sensory neuropathy (PSN) relative to cumulative dose of oxaliplatin between treatment group and placebo group. Main Secondary Objective : Compare the response rate (RR) between treatment group and placebo group in order to ensure that the efficacy of the chemotherapy is not compromised by the addition of xaliproden to the chemotherapeutic regimen. Other Secondary Objectives : study of the neurotoxicity parameters (Duration of oxaliplatin-induced PSN (G2,3,4); overall incidence of PSN during treatment; dose of onset of PSN ; incidence of dose-reduction and dose delay due to PSN; incidence of oxaliplatin treatment discontinuation due to PSN; change in Nerve Conduction Studies (NCS)) ; study of the safety profile (other than PSN) ; study of the chemotherapy efficacy (progression free survival, overall survival).

The overall objective of this study is to conduct a three-arm randomized controlled trial to evaluate the impact of an interactive, web-based decision aid on shared decision-making and patient adherence to colorectal cancer (CRC) screening recommendations.

RATIONALE: Evaluating the knowledge and attitudes of healthy participants toward a new diet and gene test for colorectal cancer risk may help doctors improve acceptance of colorectal cancer screening. PURPOSE: This clinical trial is studying the knowledge and attitudes of healthy participants toward genetic and environmental risk assessment for colorectal cancer.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of folic acid may be an effective way to prevent colorectal cancer in patients with polyps that have been surgically removed. PURPOSE: Randomized phase II trial to study the effectiveness of high-dose folic acid in preventing colorectal cancer in patients who have had polyps surgically removed within 18 months of the trial.

RATIONALE: Celecoxib may be effective in preventing colorectal cancer in patients who have a history of rectal polyps or colorectal neoplasia. PURPOSE: Randomized phase II trial to study the effectiveness of celecoxib in preventing colorectal cancer in patients who have a history of rectal polyps or colorectal neoplasia.

This is a Phase I safety study of a gene transfer drug for colorectal cancer that has spread to the liver. The main purpose of this study is to determine if it is safe to give this new intervention to persons with cancer, but we will also look for indications that the drug is effective. Although the findings in animals that have cancer are encouraging, this is the first time humans will receive this experimental gene transfer drug. A gene called cyclin G1 has been shown to play a very important part in cancer growth. In animal experiments, a genetically modified virus (or vector)carrying a modified cyclin G1 gene caused the cancerous tumors to grow much slower or even die. In this safety study, the drug will be injected through the liver artery to get it near the cancer that has spread to the liver. The way the gene gets into the cancer cells is by using a targeted vector that concentrates in the area of the cancer to improve the delivery of the killing gene into cancer cells. The vector we are using is a virus that has been changed so that the infectious genes have been removed and instead carries the modified cyclin G1 gene.

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development of cancer. Curcumin may be effective in preventing the development of colon cancer. PURPOSE: Phase I trial to determine the dose amount of curcumin that can be tolerated to help in preventing colon cancer in healthy men and women.

This phase I trial studies how well dolcanatide works in preventing colorectal cancer in healthy participants. Dolcanatide is similar to a natural hormone released into the intestine. It is thought that people who have low levels of the hormone are more likely to get colon cancer. It may be possible to prevent colon cancer by giving a drug that is similar to the hormone, such as dolcanatide.
