Active clinical trials for "Colorectal Neoplasms"

RATIONALE: Drugs used in chemotherapy, such as irinotecan, fluorouracil, leucovorin, and oxaliplatin, work in 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 combination chemotherapy as first-line therapy in treating patients who have metastatic colorectal cancer.

RATIONALE: OSI-7904L may stop the growth of tumor cells by blocking the enzymes necessary for their growth. Drugs used in chemotherapy, such as oxaliplatin, work in different ways to stop tumor cells from dividing so they stop growing or die. Combining OSI-7904L with oxaliplatin may kill more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of OSI-7904L and oxaliplatin in treating patients with refractory or recurrent advanced colorectal 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 may kill more tumor cells. It is not yet known which treatment regimen is more effective for colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of immediate with delayed fluorouracil plus leucovorin in treating patients with advanced colorectal cancer without signs or symptoms of disease.

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 cancer cells. It is not yet known which chemotherapy regimen is more effective for metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of intrahepatic floxuridine, leucovorin, and dexamethasone with that of systemic fluorouracil and leucovorin in treating patients who have unresectable liver metastases from colorectal cancer.

RATIONALE: Cryosurgery for liver metastases may have fewer side effects and improve recovery. PURPOSE: Phase II trial to study the effectiveness of cryosurgery for patients with unresectable liver metastases from colorectal 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 may kill more tumor cells. PURPOSE: Phase I trial to study the effectiveness of raltitrexed and fluorouracil in treating patients who have colorectal cancer that is metastatic, recurrent, or cannot be surgically removed.

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 after surgery may kill more tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of fluorouracil and leucovorin with or without irinotecan in treating patients who have undergone surgery for stage III colorectal cancer.

RATIONALE: Biological therapies such as gefitinib may interfere with the growth of tumor cells and slow the growth of the tumor. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug with gefitinib may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of gefitinib and oxaliplatin combined with leucovorin and fluorouracil in treating patients who have advanced solid tumors or colorectal cancer.

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving the drugs in different combinations may kill more tumor cells. PURPOSE: Phase II trial to compare the effectiveness of either irinotecan or fluorouracil plus leucovorin in treating patients who have metastatic colorectal cancer that has been previously treated with oxaliplatin with or without irinotecan.
