Cyclophosphamide and Celecoxib in Treating Patients With Advanced Cancer
RATIONALE: Drugs used in chemotherapy, such as cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Celecoxib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving cyclophosphamide together with celecoxib may help kill more cancer cells.
PURPOSE: This phase I trial is studying the side effects and best dose of celecoxib when given together with cyclophosphamide in treating patients with advanced cancer.
Unspecified Adult Solid Tumor, Protocol Specific

- To describe the toxicities of oral cyclophosphamide when administered with escalating doses of celecoxib in patients with advanced malignancies.
- To evaluate the effects of this regimen on plasma levels of vascular endothelial growth factor.
OUTLINE: This is a dose-escalation study of celecoxib.
In the first course, patients receive oral cyclophosphamide once daily on days 1-35 and oral celecoxib twice daily on days 8-35. In all subsequent courses, patients receive oral cyclophosphamide once daily and oral celecoxib twice daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Blood samples are collected at baseline, periodically during treatment, and at time of tumor progression. Samples are analyzed for vascular endothelial growth factor levels and stored for future analysis of circulating DNA of angiogenic biomarkers.
After completion of study therapy, patients are followed periodically.
