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.
OBJECTIVES: I. Determine the response rate of patients with irinotecan-refractory, stage IV colorectal cancer when treated with cetuximab. II. Determine the safety and toxic effects of this drug in these patients. III. Determine the time to progression of patients treated with this drug.
OUTLINE: This is a multicenter study. Patients receive cetuximab IV over 1-2 hours weekly for 6 weeks. Treatment repeats in the absence of disease progression or unacceptable toxicity. Patients are followed at 4 weeks and then every 3 months thereafter.
PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study within 4 months.
Primary Purpose: Treatment

In this study, the investigational drug, temsirolimus, will be combined with cetuximab, a biologic agent used in the treatment of colorectal cancer. Cetuximab in combination with temsirol...
To evaluate the emergence of RAS mutation in patients with metastatic colorectal cancer, circulating free DNA will be analyzed using mass spectrometric genotyping in subjects during cetuxi...
The purpose of this clinical research study is to learn about the safety of cetuximab in patients with stage IV colorectal cancer, and who may benefit from cetuximab.
This study is being performed to test if the use of high dose of cetuximab in combination with irinotecan overcomes the resistance seen with standard dose of cetuximab plus irinotecan in p...
To compare the efficacy in terms of progression free survival (PFS) of the addition of cetuximab to FOLFIRI versus FOLFIRI alone given as first line therapy in patients with advanced color...
Colorectal cancer is the second most common cancer, representing 13% of all diagnosed cancers. Cetuximab is a recombinant chimeric monoclonal IgG1 antibody and epidermal growth factor receptor (EGFR) ...
This study aimed to investigate theranostic strategies in colorectal and skin cancer based on fragments of cetuximab, an anti-EGFR mAb, labeled with radionuclide with imaging and therapeutic propertie...
Few clinical studies have investigated the association between neutrophil-lymphocyte ratio (NLR) and treatment with cetuximab-based chemotherapy in metastatic colorectal cancer (mCRC). The NLR may ref...
Therapies may be more efficacious when targeting a patient subpopulation with specific attributes, thereby enhancing the cost-effectiveness of treatment. In the CRYSTAL study, patients with metastatic...
The present study investigated the molecular mechanism by which the epidermal growth factor receptor (EGFR) inhibitor cetuximab enhances the antitumor activity of the mitogen-activated protein kinase ...
Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.
Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).
Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.
A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.
Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.
