Brief Summary: RATIONALE Monoclonal antibodies such as 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 Cetuximab may also stop the growth of colorectal cancer by blocking blood flow to the tumor Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth Giving cetuximab together with celecoxib may kill more tumor cells

PURPOSE This phase II trial is studying how well giving cetuximab together with celecoxib works in treating patients with metastatic colorectal cancer or colorectal cancer that cannot be removed by surgery
Detailed Description: OBJECTIVES

Primary

Determine the time to progression in patients with unresectable or metastatic colorectal cancer treated with cetuximab and celecoxib

Secondary

Determine the response rate median survival and 1-year survival rate of patients treated with this regimen
Determine the toxicity profile of this regimen in these patients
Determine the feasibility of testing urinary PGE-M in patients treated with this regimen
Determine the feasibility of testing serum transforming growth factor-α and amphiregulin in patients treated with this regimen
Determine the effects of this regimen on the EGFR pathway in tumor cells ie phosphorylated EGFr phosphorylated AKT activated mitogen-activated protein kinase
Determine the effects of this regimen on the cyclooxygenase-2 pathway in tumor cells by measuring PGE-2 levels

OUTLINE Patients receive cetuximab IV over 1-2 hours once weekly and oral celecoxib twice daily on days 1-28 Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity

Serum and urine samples are collected at baseline after week 1 and every other course thereafter for evaluation of PGE-2 by mass spectrometry cyclooxygenase-2 activity and phospho-EGFR levels by western blot analysis and immunohistochemistry Samples are also analyzed for TGF-α and amphiregulin proteomics

PROJECTED ACCRUAL A total of 54 patients will be accrued for this study
