Active clinical trials for "Colonic Neoplasms"

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.

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)

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.

This phase I trial is studying the side effects and best dose of suberoylanilide hydroxamic acid when given together with fluorouracil, leucovorin, and oxaliplatin in treating patients with progressive metastatic or unresectable colorectal cancer or solid tumor. Drugs used in chemotherapy, such as suberoylanilide hydroxamic acid, fluorouracil, leucovorin, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Suberoylanilide hydroxamic acid may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving more than one drug (combination chemotherapy) may kill more tumor cells.

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.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving drugs in different ways may kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of chemotherapy given in different ways in treating patients with surgically removed stage II or stage III colon cancer at high risk of recurrence.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug and giving them in different ways may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of melphalan given as an isolated hepatic perfusion followed by chemotherapy infused into the liver in patients who have unresectable colorectal cancer that is metastatic to the liver.

This study will test the effectiveness of an experimental treatment for peritoneal cancer involving surgical removal of the tumor, perfusion of the abdomen during surgery with a heated solution of the drug cisplatin, and post-surgery combination chemotherapy in the abdomen with fluorouracil (5-FU) and paclitaxel. Patients with certain peritoneal cancer whose tumors are confined to the abdomen may be eligible for this study. Candidates are screened with a medical history and physical examination, including blood tests, electrocardiogram and possibly bone scan, brain magnetic resonance imaging (MRI), and chest, abdomen and pelvic CT scans. Participants undergo surgery to remove as much tumor as possible. Part of the intestines, pancreas, stomach or the entire spleen may also be removed if they are affected. During surgery, after the tumor has been removed, two catheters (thin plastic tubes) are placed in the abdomen. A chemotherapy solution containing the anti-cancer drug cisplatin heated to a temperature of about 108.6 degrees (10 degrees above normal body temperature) is then delivered into the abdomen through one catheter and drained through another. During treatment, a drug called sodium thiosulfate is given through a vein to reduce the risk of side effects of cisplatin, particularly kidney damage. After 90 minutes of bathing the abdomen with this solution, the drug is rinsed from the abdomen and the catheters removed. Another small catheter is then placed and left inside the abdomen with one end coming out through the skin. Seven to 12 days after the operation, the anti-cancer drugs 5-FU and paclitaxel are given through this catheter. After complete recovery from the surgery, the catheter is removed and the patient is discharged from the hospital. Clinic visits are scheduled for periodic follow-up examination, imaging, and tests 3 and 6 months after surgery and every 6 months for up to 5 years as long as the disease does not worsen. Patients whose disease progresses are taken off the study and referred back to their local physician or referred for alternative care or other research studies. Patients are also asked to assess how this therapy affects their general health and well being. This will require filling out two quality-of-life (QOL) questionnaires before surgery and again at each follow-up visit after surgery. Each questionnaire takes about 15 minutes to complete.

EP2101 is a new cancer vaccine containing 10 different peptide antigens. The vaccine is designed to activate the immune system to develop a response against tumor cells in order to delay or prevent the recurrence of cancer. This study will test the safety and measure the level of immune stimulating capability of EP2101 in patients with Colon Cancer.

Randomized phase III trial to compare the effectiveness of fluorouracil given by infusion with that of fluorouracil plus eniluracil given by mouth in treating patients who have metastatic, recurrent, or residual advanced colorectal cancer. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. It is not yet known if fluorouracil is more effective with or without eniluracil for advanced colorectal cancer
