Active clinical trials for "Colorectal Neoplasms"

The aim is to conduct a prospective multicentre randomised study comparing two different control regimens after resection for colorectal cancer stage II - III. Follow-up after surgery for colorectal cancer is a controversial issue. The reasons for follow-up are: to obtain a better overall survival, for scientific purposes and/or for psychological reasons and/or as quality assessment. Meta-analyses of randomised controlled studies have lately shown that a beneficial effect on the overall mortality could be found with intense follow-up compared to sporadic. This study compares the regimen of CT-scan or MR scan of the liver, control of the carcinoembryonic antigen (CEA), and CT-scan or X-ray of the lungs in two groups with either control after 12 and 36 months, or after 6, 12, 18, 24, and 36 months. The efficacy parameters are total and cancer-specific mortality.

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: Randomized phase III trial to compare the effectiveness of intravenous infusion or intrahepatic infusion of fluorouracil and leucovorin in treating patients with colorectal cancer metastatic 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, giving the drugs in different ways, and combining chemotherapy with radiation therapy may kill more tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy plus fluorouracil and leucovorin before surgery given with or without fluorouracil and leucovorin after surgery in patients with locally advanced rectal 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/II trial to study the effectiveness of combination chemotherapy consisting of fluorouracil, leucovorin, and gemcitabine in treating patients with recurrent or metastatic colorectal cancer.

RATIONALE: Drugs used in chemotherapy, such as fluorouracil, leucovorin, and irinotecan, use different ways to stop tumor cells from dividing so they stop growing or die. Giving more than one chemotherapy drug may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving fluorouracil together with leucovorin and irinotecan works in treating patients with recurrent or refractory metastatic unresectable 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 which regimen of chemotherapy is more effective for metastatic colorectal cancer. PURPOSE: Phase III trial to compare the effectiveness of three chemotherapy regimens in treating 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. Combining more than one drug may kill more tumor cells. It is not yet known which regimen of combination chemotherapy is more effective for metastatic colorectal cancer. PURPOSE: Randomized phase III trial to compare the effectiveness of two combination chemotherapy regimens in treating patients who have metastatic colorectal cancer.

The specific aims of this study are as follows: Primary endpoint: to evaluate the clinical responses of vaccinated patients. Secondary endpoint: to evaluate the safety of this treatment and the immune responses against CEA before and after the treatment

This study is a Phase I/II study. In Phase I of this study, the objective is to determine the maximum tolerated dose (MTD) of combination therapy with Aroplatin and capecitabine in subjects with unresectable, local recurrence or distant metastases of colorectal cancer refractory to 5-FU/leucovorin and irinotecan. In Phase II, the primary objective is to evaluate the response proportion and duration with Aroplatin/capecitabine therapy. Secondary objectives are to evaluate frequency and severity of adverse events.

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 combination chemotherapy in treating patients who have metastatic colorectal cancer that has not responded to previous chemotherapy.
