Active clinical trials for "Colorectal Neoplasms"

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. It is not yet known which regimen of combination chemotherapy is more effective in treating patients with recurrent or metastatic colorectal cancer. PURPOSE: Randomized phase III trial to study the effectiveness of combining fluorouracil, leucovorin, and oxaliplatin in different ways in treating patients with recurrent or metastatic colorectal cancer.

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: 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 radiation therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy consisting of fluorouracil-uracil and leucovorin plus radiation therapy in treating patients with colorectal cancer who have undergone surgery to remove the tumor.

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 work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, 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. Bevacizumab (Bv) may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving combination chemotherapy together with bevacizumab after surgery may kill any tumor cells that remain after surgery. It is not yet known whether giving combination chemotherapy together with bevacizumab is more effective than combination chemotherapy alone in treating colon cancer in adjuvant setting. PURPOSE: This randomized phase III trial is studying two different combination chemotherapy regimens with or without bevacizumab to compare how well they work in treating patients who have undergone surgery for high risk stage II or stage III colon 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. PURPOSE: Phase II trial to study the effectiveness of BMS-247550 in treating patients who have recurrent or metastatic colorectal cancer.

RATIONALE: 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 irinotecan is more effective with or without oxaliplatin in treating metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of irinotecan with or without oxaliplatin in treating patients who have metastatic colorectal cancer.
