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. PURPOSE: Clinical trial to study the effectiveness of oxaliplatin in treating patients who have locally advanced or metastatic colorectal cancer that has been previously treated.

RATIONALE: Monoclonal antibodies, such as cetuximab, can 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. PURPOSE: Phase II trial to study the effectiveness of cetuximab and irinotecan in treating patients who have advanced colorectal cancer that has not responded to previous treatment.

RATIONALE: Eniluracil may increase the effectiveness of chemotherapy by blocking tumor enzymes that break down chemotherapy drugs. PURPOSE: Randomized phase II trial to determine the effectiveness of eniluracil followed by surgery in treating patients who have primary or metastatic colorectal cancer.

The purpose of this study is test the safety of Tarceva, find the best dose, and see what effects (good and bad) it has on you and your colorectal cancer. The effects of Tarceva will be evaluated in combination with 5-fluorouracil, leucovorin, and irinotecan, with or without Bevacizumab.

This multi-center photodynamic therapy study plans to treat patients with large tumors in any superficial location, sarcoma, tumors of oral/oro-pharyngeal cavity, tumors with extensive pelvic involvement, or liver metastasis. The treatment is limited to patients that have failed to respond to currently approved methods of treatment. The study involves a single, intravenous administration of an investigational drug, LS11 (previously studied in approximately 80 cancer patients) and the placement of a novel, flexible light delivery catheter inside the tumor by a minor surgical procedure. The activation of LS11 by the light delivery catheter over a period of 1-24 hrs may result in destruction of tumor tissue.

RATIONALE: Vaccines made from a peptide may make the body build an immune response and kill tumor cells. PURPOSE: Randomized phase I trial to study the effectiveness of vaccine therapy in treating patients who have metastatic cancer that has not responded to previous therapy.

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. It is not yet known which chemotherapy regimen is most effective for colorectal cancer that has spread to the liver. PURPOSE: Randomized phase III trial to compare the effectiveness of combination chemotherapy with or without isolated hepatic perfusion with melphalan 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. Biological therapies such as gefitinib may interfere with the growth of the tumor cells and slow the growth of colorectal cancer. Combining chemotherapy with gefitinib may kill more tumor cells. PURPOSE: Phase I/II trial to compare the effectiveness of chemotherapy with or without gefitinib in treating patients who have metastatic or locally recurrent colorectal cancer.

RATIONALE: Embolization blocks blood flow to part of an organ and/or tumor. Blocking the portal vein on one side of the liver may cause the opposite side of the liver to increase in size and decrease the risk of liver failure following surgery. PURPOSE: Phase II trial to study the effectiveness of portal vein embolization in treating patients who have liver metastases from primary colorectal cancer.

RATIONALE: Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining biological therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase I/II trial to study the effectiveness of biological therapy combined with chemotherapy in treating patients who have metastatic kidney cancer or colorectal cancer.
