RATIONALE: Drugs used in chemotherapy such as paclitaxel work in different ways to stop tumor cells from dividing so they stop growing or die. Celecoxib may stop the growth of cancer by stopping blood flow to the tumor and may increase the effectiveness of paclitaxel by making tumor cells more sensitive to the drug. Combining celecoxib with paclitaxel may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining paclitaxel with celecoxib in treating patients who have recurrent or persistent platinum-resistant ovarian epithelial or primary peritoneal cancer.

Condition	Treatment or Intervention	Phase
recurrent ovarian epithelial cancer peritoneal cavity cancer	Drug: celecoxib  Drug: paclitaxel  Procedure: anti-cytokine therapy  Procedure: antiangiogenesis therapy  Procedure: biological response modifier therapy  Procedure: chemosensitization/potentiation  Procedure: chemotherapy  Procedure: growth factor antagonist therapy	Phase II

OBJECTIVES:

• Determine the antitumor activity of paclitaxel and celecoxib in patients with recurrent or persistent platinum-resistant ovarian epithelial or primary peritoneal cancer.
• Determine the nature and degree of toxicity of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15 and oral celecoxib twice daily on days 2-6, 9-13, and 16-27. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for 2 years and then every 6 months for 3 years.

PROJECTED ACCRUAL: A total of 19-51 patients will be accrued for this study within 11-22 months.

Ages Eligible for Study:  18 Years and above,  Genders Eligible for Study:  Both
