Celecoxib in Preventing Cancer in Patients With Oral Leukoplakia and/or Head and Neck Dysplasia
RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. Celecoxib may be effective in preventing head and neck cancer in patients who have oral leukoplakia or head and neck dysplasia.
PURPOSE: Phase II trial to study the effectiveness of celecoxib in preventing cancer in patients who have oral leukoplakia and/or head and neck dysplasia.
- Determine the response rate, in terms of prostaglandin E2 expression, in patients with oral leukoplakia and/or dysplasia treated with celecoxib.
- Determine the change in other biomarkers including COX-2, Ak+, Ki-67, BCL2, BAX, VEGF, and CD31, in patients treated with this drug.
- Determine the efficacy of this drug, in terms of reducing the size of oral leukoplakia lesions and presence of dysplasia, in these patients.
- Correlate change in biomarker expression with response of oral leukoplakia lesions and/or dysplasia in patients treated with this drug.
- Determine the toxic effects of this drug in these patients.
OUTLINE: This is an open-label, multicenter study.
Patients receive oral celecoxib twice daily for 3 months. After 3 months, patients undergo a repeat biopsy. Patients with a positive response receive celecoxib for an additional 9 months.
Patients are followed every 3-6 months for 1 year.
PROJECTED ACCRUAL: A total of 20 patients will be accrued for this study within 30 months.

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...

Medical and Biotech [MESH] Definitions
Soft tissue tumors or cancer arising from the mucosal surfaces of the LIP; oral cavity; PHARYNX; LARYNX; and cervical esophagus. Other sites included are the NOSE and PARANASAL SINUSES; SALIVARY GLANDS; THYROID GLAND and PARATHYROID GLANDS; and MELANOMA and non-melanoma skin cancers of the head and neck. (from Holland et al., Cancer Medicine, 4th ed, p1651)
Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
A form of RHABDOMYOSARCOMA arising primarily in the head and neck, especially the orbit, of children below the age of 10. The cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. This cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (From Holland et al., Cancer Medicine, 3d ed, p2188)
A symptom, not a disease, of a twisted neck. In most instances, the head is tipped toward one side and the chin rotated toward the other. The involuntary muscle contractions in the neck region of patients with torticollis can be due to congenital defects, trauma, inflammation, tumors, and neurological or other factors.
Large veins on either side of the root of the neck formed by the junction of the internal jugular and subclavian veins. They drain blood from the head, neck, and upper extremities, and unite to form the superior vena cava.
