Filter by:RATIONALE: Monoclonal antibodies, such as Cetuximab, can target tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.This is an anti-cancer drug which has already been approved by the FDA for use in patients who have Colorectal Cancer. Cetuximab 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. Radiation Therapy uses high-energy x-rays to kill tumor cells and cause less damage to normal tissue . Giving the drug Cetuximab together with Radiation Therapy may kill more tumor cells. Surgery is the most common treatment for Colorectal Cancer to remove the tumor, as well as a small margin of surrounding normal tissue and possibly nearby lymph nodes. Surgery is usually used in conjunction with other conventional treatments such as Radiation Therapy. Radiation Therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Radiation Therapy after surgery may kill any tumor cells that remain after surgery. Screening test such as Fecal Occult Blood Test (FOBT) and Colonoscopy has to be done. Tumor markers for Colorectal Carcinoma are Carcinoembryonic antigen (CAE) and CA 19-9 and to assess the response of tumor markers Carcinoembryonic antigen (CAE) and CA 19-9 will be used and periodically Colonoscopy has to be done. Colorectal Cancer Surgery are Colon resection (Colectomy), Rectum resection (Proctectomy), Colostomy, and Radiofrequency ablation. PURPOSE: Determine the tumor response rate treated with Cetuximab and Radiation Therapy Vs Surgery before or after Radiation Therapy in patients with Colorectal Cancer from stage II to IV
The purpose of this study is to determine whether MRI with manganese containing contrast agent detects more livermetastasis compared to CT scan
This single arm study will assess the efficacy and safety of a combination of modified FOLFIRI (irinotecan, 5-FU and leucovirin), Avastin and cetuximab in patients with previously untreated metastatic colorectal cancer. Patients will receive modified FOLFIRI (irinotecan 180mg/m2 iv, leucovirin 200mg/m2 iv, and 5-FU 400mg/m2 iv) on day 1 of each 2 week cycle, in combination with Avastin (5mg/kg iv on day 1 of each cycle) and cetuximab (loading dose of 400mg/m2 followed by 250mg/m2 on day 3 of each cycle). The anticipated time on study treatment is until disease progression or unacceptable toxicity, and the target sample size is <100 individuals.
When used with a different radioactive tracer called FMISO, a PET scan can find areas of low oxygen in the tumor. We think that having areas of low oxygen is a reason why some tumors are hard to treat with radiation. In a past study, FMISO PET scans were performed in 6 patients with rectal cancer that could not be operated on and that had spread to other areas. In this group of patients, FMISO PET scans were able to find the low oxygen areas in their tumors. But this study included only a few patients. In the present study, we want to use FMISO PET scans in patients who have tumors that can be operated on. This group of patients will have radiation, chemotherapy or both before they have their surgery. We want to see if FMISO PET can find low oxygen areas in this distinct group of patients.
RATIONALE: Monoclonal antibodies, such as cetuximab and 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 may also stop the growth of tumor cells by blocking blood flow to the tumor. Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving monoclonal antibodies together with combination chemotherapy may kill more tumor cells. PURPOSE: This randomized phase II trial is studying how well giving cetuximab together bevacizumab works as first-line therapy, followed by combination chemotherapy and bevacizumab with or without cetuximab as second-line therapy in treating patients with stage IV colorectal cancer.
The study will compare patient's experience between those taking a standard bowel cleansing regimen with minimal laxative tagging regimen of senna and gastrofin. Additionally comparing any possible reduction in diagnostic accuracy that may ensue from an increased quantity of retained faecal residue.
RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, 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 may also stop the growth of tumor cells by blocking blood flow to the tumor. Radiofrequency ablation uses a high-frequency, electric current to kill tumor cells. Giving chemotherapy and bevacizumab before surgery or radiofrequency ablation may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well giving oxaliplatin and capecitabine together with bevacizumab followed by surgery and/or radiofrequency ablation works in treating patients with colorectal cancer that has spread to the liver and cannot be removed by surgery.
The purpose of this clinical trial is to determine whether the combination of 5-fluorouracil (5-FU) plus a DAVANAT (carbohydrate polymer) along with Avastin and Leucovorin (LV) is beneficial in treating colorectal cancer in patients unable to tolerate intensive chemotherapy.
Hepatic artery infusion (HAI) with oxaliplatin (OX), systemic 5 fluorouracil (5FU), and leucovorin (HAI/OX/FU) will be implemented using an interventional radiology technique to obviate the need for initial major surgery (catheter placement) in patients who have unresectable liver metastasis from colorectal cancer. The study goal is to reduce tumor size to make possible a complete resection of all lesions. Secondary goals are to reduce or eliminate the complexity usually associated with HAI, to accomplish most or all of the treatment as an outpatient, to reduce costs, and to avoid the hepatotoxicity associated with HAI/floxuridine (FUDR). Oxaliplatin has been selected because of its ease of use, known toxicology, and established efficacy in colorectal cancer.
The aim of the study is to determine if Iressa added to chemotherapy with Irinotecan, 5Fluorouracil and Leucovorin can prolong the period of time without any disease worsening (Time to Progression) in patients with metastatic colorectal cancer.
