Active clinical trials for "Colorectal Neoplasms"

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.

RATIONALE: Drugs used in chemotherapy such as irinotecan, capecitabine, leucovorin, and fluorouracil use different ways to stop tumor cells from dividing so they stop growing or die. Celecoxib may stop the growth of colorectal cancer by stopping blood flow to the tumor. It is not yet known which combination chemotherapy regimen with or without celecoxib is more effective in treating metastatic colorectal cancer. PURPOSE: This randomized phase III trial is studying two combination chemotherapy regimens and celecoxib to see how well they work compared to two combination chemotherapy regimens alone in treating patients with metastatic colorectal cancer.

The purpose of this study is to evaluate how tumors in patients with colorectal carcinoma respond to treatment with VELCADE alone versus VELCADE given with irinotecan, and also to see what effects (good and bad) it has on you and your cancer.

The purpose of this study is to compare overall survival in patients with previously-treated metastatic, epidermal growth factor receptor (EGFR)-positive colorectal cancer treated with oxaliplatin, 5-fluorouracil and leucovorin (FOLFOX4) and cetuximab with FOLFOX4 alone.

The purpose of the present study is to investigate the benefit of anti-cancer therapy administered on the basis of drug sensitivity testing. This concerns colorectal cancer patients who have previously received standard treatment.

Colorectal cancer is the fourth most common cancer in the UK. Surgical resection is the mainstay of curative therapy. With the screening program enabling early detection, surgery plays an important role in treatment strategies. Surgery imparts a significant physiological and psychological stress on cancer patients.Recent research has demonstrated that a fast-track approach utilising regional anaesthesia, early mobilisation and good oral intake can improve outcomes by reducing the physiological stress response to surgery. The primary objective of this study is to determine whether a defined exercise programme can improve recovery and reduce complications after surgery.

Treatment of patients with metastatic colorectal carcinoma is surgical resection. Only 10-15% of the patients will be candidates for curative resection. After response to chemotherapy this figure rises 10-13% more. To perform the surgery it is necessary to have a sufficient remnant liver volume (RLV), which allows maintaining optimal liver function after resection. If the estimated RLV is insufficient preoperatively, portal venous embolization site (PVE) is performed for compensatory hypertrophy, thus increasing the number of resections 19%. Still, in 20% of these patients surgery can not be performed because RLV is not achieved or because the disease progresses while waiting for growth. Therefore, it is necessary to improve liver regeneration without promoting tumor growth. Studies on liver regeneration, have determined that cells (CD133 +) are involved in the liver hypertrophy that occurs after hepatectomy. CD133 + have been used to induce liver hypertrophy with encouraging results. This population of CD133 +, can be selected from peripheral blood after stimulation with Granulocyte colony-stimulating factor (G-CSF), being able to obtain a large number of them. The investigators propose to treat patients who do not meet criteria for surgery because of insufficient volume <40%, with CD133 + and portal embolization in order to carry out a surgical resection in a second place.

Using Moviprep patients use shorter time to do a bowel prep before colonoscopy. No major single center has docuemted the advantage of using moviprep as bowel prep before colonoscopy.This randomised study was conducted to compare moviprep with the present standard: Phosphoral to investigate the degree of bowel cleasing before colonoscopy in patients suspected of colorectal cancer, and to investigate number of days where patients need to stay home.
