Active clinical trials for "Colonic Neoplasms"

RATIONALE: Drugs used in chemotherapy, such as tegafur-uracil, leucovorin, and S-1, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving tegafur-uracil together with leucovorin is more effective than giving S-1 in treating patients with stage III colon cancer. PURPOSE: This randomized phase III trial is studying giving tegafur-uracil together with leucovorin to see how well it works compared with giving S-1 in treating patients with stage III colon cancer that has been completely removed by surgery.

This study is for people with solid tumors cancer for which the standard chemotherapy drugs have not worked. The purpose of this research is to evaluate the side effects of Xeloda (also called capecitabine) in combination with a new anticancer agent called Gleevec (also called imatinib mesylate). Xeloda is an anticancer drug, and can be taken by mouth. The active ingredient is a well-studied cancer drug called 5-FU. Xeloda is approved by the FDA for the treatment of colon cancer. Gleevec is approved in the US for the treatment of patients with a leukemia called CML (increase of white blood cells) after failure of standard therapy. It is also approved by the FDA for patients with Gastrointestinal Stromal Tumors (a rare tumor in the digestive tract). This study will test how much Gleevec we can safely give with Xeloda. Xeloda will be given at the recommended dose for colorectal cancer and Gleevec will be given in increasing amounts.

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, leucovorin, or fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving combination chemotherapy with or without cetuximab after surgery may kill any remaining tumor cells and keep colon cancer from coming back. It is not yet known whether giving combination chemotherapy together with cetuximab is more effective than giving combination chemotherapy alone in treating colon cancer. PURPOSE: This randomized phase III trial is studying combination chemotherapy and cetuximab to see how well they work compared to combination chemotherapy alone in treating patients with stage III colon cancer that was completely removed by surgery.

To evaluate the FOLFOX regimen versus LV5FU2 in the adjuvant treatment of stage II and III colon cancer. Primary objective: Disease Free Survival (DFS) Secondary objective: Overall Survival (OS), safety (including long term toxicity)

Resveratrol is purported to possess cancer preventive activity, especially for colon cancer, though its mechanisms of action are not well defined. Resveratrol is found in the skin of grapes and has anti-oxidative and pro-apoptotic effects on cancer cell lines in vitro. The main dietary sources of resveratrol are grapes, grape products, and red wine, and small amounts may be found in mulberries. A prior report and compelling preliminary data from our laboratory suggest that resveratrol modulates Wnt signaling, a signaling pathway which is activated in over 85% of colon cancers. In this proposal, studies were performed to define the actions of resveratrol on the Wnt signaling pathway in a clinical trial in which patients with colon cancer received treatment with Resveratrol, and correlative laboratory studies examined its effects directly on colon cancer and normal colonic mucosa. These studies provided data on the mechanisms of resveratrol action and provided a foundation for future prevention trials, correlative studies and therapeutic clinical research with this agent.

The purpose of the study is to verify superiority of 1-LV/5FU therapy to UFT Therapy of relapse-free survival time in patients with Dukes C and Cure A colon cancer. Secondary endpoints include disease-free survival time, survival time, and safety.

The recent introduction of robotic surgical system has revolutionized the field of minimally invasive surgery. The investigators hypothesized that adoption of a robotic surgical system for patients with right-side colon cancer seems appealing because This system provides high-definition three-dimensional vision, eliminates physiologic tremor, and better ergonomics. This randomized controlled trial was designed to determine the safety and efficacy of robotic right hemicolectomy in comparison with laparoscopic right hemicolectomy.

The present feasibility study is designed to find out whether pre-treatment with the compound mangafodipir lowers the frequency and severity of side effects during adjuvant chemotherapy according to the FOLFOX6 regimen in patients operated upon colon cancer in stage Dukes' C.

This is a randomized, parallel, multi-center, single-blind study, comparing BLI850 to an FDA approved bowel preparation in adult subjects undergoing colonoscopy.

This clinical trial will compare the efficacy and safety of the combination of AMG 386 and FOLFIRI with FOLFIRI alone in second line treatment of metastatic colorectal cancer.
