Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of sulindac may be an effective way to prevent colon cancer. Eating a diet rich in fruits and vegetables appears to reduce the risk of some types of cancer. Curcumin, rutin, and quercetin are compounds found in plants that may prevent the development of colon cancer. PURPOSE: Randomized clinical trial to study the effectiveness of sulindac, curcumin, rutin, and quercetin in preventing colon cancer.

RATIONALE: Monoclonal antibodies can find and locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. 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 combining chemotherapy with monoclonal antibody therapy may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy plus combination chemotherapy in treating patients with advanced colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: Phase II trial to study the effectiveness of irinotecan in treating patients with metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy, such as capecitabine and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. PURPOSE: This phase II trial is studying how well giving capecitabine together with oxaliplatin works in treating older patients with metastatic colorectal cancer.

The purpose of this study is to evaluate oncological outcome of patients for T3 and T4 colorectal cancer undergoing laparoscopic versus open surgery.

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 may kill more tumor cells. Leucovorin may increase the effectiveness of fluorouracil by making tumor cells more sensitive to the drug. PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy consisting of oxaliplatin, fluorouracil, and leucovorin in treating patients who have colorectal cancer.

RATIONALE: Radiofrequency ablation may be able to shrink or destroy cancer cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Chemotherapy delivered directly into the blood vessels of the liver may prevent new tumors from growing. Combining these therapies may be an effective treatment for colorectal cancer that has spread to the liver. PURPOSE: Phase II trial to study the effectiveness of radiofrequency ablation followed by chemotherapy delivered directly into the blood vessels of the liver in treating patients who have colorectal cancer that has spread to the liver.

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 may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of fluorouracil-uracil and leucovorin in treating elderly patients who have metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. SU5416 may stop the growth of colorectal cancer by stopping blood flow to the tumor. It is not yet known whether chemotherapy is more effective with or without SU5416 in treating metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of leucovorin and fluorouracil with or without SU5416 in treating patients who have metastatic colorectal cancer.

The purpose of this study is to compare treatment with oxaliplatin/5-FU/leucovorin plus vatalanib versus oxaliplatin/5-FU/leucovorin plus placebo in patients with colorectal cancer that has spread to other organs and whose disease has worsened after treatment with irinotecan.
