|Brief Title ICMJE||Dexamethasone, Aspirin, and Diethylstilbestrol in Treating Patients With Locally Advanced or Metastatic Prostate Cancer|
|Official Title ICMJE||A Randomized Phase III Trial of Dexamethasone and Aspirin (DA) Versus Dexamethasone, Diethylstilbestrol and Aspirin (DAS) in Locally Advanced or Metastatic Cancer of the Prostate - Immediate Versus Deferred Diethylstilbestrol|
RATIONALE: Giving dexamethasone together with aspirin and diethylstilbestrol may be effective in lowering prostate-specific antigen levels and may slow or stop the growth of prostate cancer. It is not yet known which schedule of dexamethasone, aspirin, and diethylstilbestrol is more effective in treating prostate cancer.
PURPOSE: This randomized phase III trial is studying dexamethasone and aspirin when given together with two different schedules of diethylstilbestrol to compare how well they work in treating patients with locally advanced or metastatic prostate cancer.
OUTLINE: This is a randomized, controlled, multicenter study. Patients are stratified according to ECOG performance status (0 vs 1-3), prostate-specific antigen (PSA) response to prior therapy (PSA normalization vs inability to normalize), and bone scan (positive vs negative for bony metastases). Patients are randomized to 1 of 2 treatment arms.
Quality of life is evaluated monthly during study treatment.
After completion of study treatment, patients are followed every 3 months for 1 year and then every 6 months thereafter.
PROJECTED ACCRUAL: A total of 260 patients will be accrued for this study.
