简要总结
RATIONALE: Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving celecoxib before surgery may reduce the amount of normal tissue that needs to be removed. Collecting and storing samples of tumor tissue, blood, and urine from patients with head and neck cancer to study in the laboratory may help doctors learn more about the cancer and predict how well patients will respond to treatment with celecoxib.
PURPOSE: This phase I/II trial is studying changes in tumor cells and how well celecoxib works in treating patients with head and neck cancer that can be removed by surgery.
详细描述
OBJECTIVES:
Primary
- Evaluate the changes in molecular markers of angiogenesis before and after treatment with celecoxib in tumor tissues of patients with resectable head and neck squamous cell carcinoma.
Secondary
- Evaluate the changes in molecular markers of angiogenesis before and after treatment with celecoxib in blood tissues of these patients.
- Evaluate the effects of celecoxib on indirect measures of tumor perfusion, as measured by perfusion CT scan, in these patients.
- Evaluate the effects of celecoxib on apoptosis and proliferation rate on tumor cells and on endothelial cells in these patients.
- Identify potential new markers of the activity of cyclooxygenase-2 inhibitors and identify new pathways of potential interests by performing gene expression profiling of tumor tissues before and after exposure to celecoxib.
