RATIONALE: Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Recombinant interferon alfa-2b may interfere with the growth of cancer cells and slow the growth of kidney cancer. Giving celecoxib together with recombinant interferon alpha-2b may kill more tumor cells and be an effective treatment for metastatic kidney cancer.
PURPOSE: This phase II trial is studying how well giving celecoxib together with recombinant interferon alfa-2b works in treating patients with metastatic kidney cancer who have undergone surgery.
I. To estimate the objective response rate of interferon alpha plus celecoxib in metastatic RCC patients with 3+ COX-2 tumor immunostaining.
I. To compare cellular immune parameters in metastatic RCC patients with 3+ COX-2 tumor immunostaining to patients with < 1+ tumor immunostaining.
II. To evaluate the effect of celecoxib and interferon alpha therapy on cellular immune parameters in metastatic RCC patients with 3+ COX-2 tumor immunostaining.
Patients receive oral celecoxib twice daily and recombinant interferon alpha-2b subcutaneously, once daily, 5 times a week. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
