VA Cooperative Study #553 is designed to prospectively evaluate the efficacy of early adjuvant chemotherapy using docetaxel and prednisone added to the standard of care for patients who are potentially cured by radical prostatectomy but who are at high risk for relapse. The standard of care is surveillance, with the addition of androgen deprivation at the time of biochemical relapse. This study will assess the effect of adding early chemotherapy to the standard of care on progression free survival in Veterans at high risk for progression after prostatectomy.
The ability of radical prostatectomy to cure prostate cancer and to therefore prevent the morbidity and mortality associated with progression to metastatic disease depends on effectively treating both local and potential systemic disease. In the United States alone, over 80,000 men per year are treated with prostatectomy to cure their disease. Because 20% of these men will be found to have locally advanced or high-grade disease, they will be at risk for relapse and morbidity from their prostate cancer. Although androgen deprivation, radiation therapy, and chemotherapy have been considered potentially effective adjuvant modalities for localized prostate cancer, there are no randomized studies that support the utility of any of these treatments as a standard of care. Ultimately, it is androgen independent prostate cancer, which causes morbidity for these patients. Docetaxel based chemotherapy has been shown to prolong survival and induce responses in up to 80% of patients with androgen independent disease, generating enthusiasm for the use of chemotherapy early in the treatment of prostate cancer. This study is designed to test the value of adjuvant chemotherapy in improving progression free survival, which is critical in preventing morbidity and mortality from relapse in patients with clinically localized, but high risk, prostate cancer.
After patients are stratified for PSA, Gleason score, tumor stage, the presence of positive margins, and the planned use of adjuvant radiation therapy, this study will randomized 300 patients from 30 VA sites, after prostatectomy, to the standard of care or to docetaxel and prednisone administered every 3 weeks for 18 weeks. Patients would then be observed with PSA for a minimum of one and a maximum of five years. The study is designed with 90% power to detect a reduction in the 5-year progression rate from 60% to 45% (15% absolute difference, 25% relative difference).
At the end of the study period (October 31, 2012), the patients in the study will continue to be passively followed for three more years. The follow-up study involved centralized remote access of the participants' medical records to obtain information on PSA levels and study endpoints.
Prostate cancer is the leading cause of malignancy for Veterans, and the second leading cause of death. Patients with high risk, localized disease account for 70% of all cancer deaths in patients treated for cure with radical prostatectomy. Effective adjuvant therapy is critical to reducing suffering and death from prostate cancer. The VA Cooperative Studies Program is uniquely placed to address this question. The VA has a longstanding history of important studies in prostate cancer, which have significantly changed the way urologic oncologists treat patients with this disease. The incidence of prostate cancer in our older, male population is substantial, the number of Veterans treated with prostatectomy continues to rise, and the incidence of high risk prostate cancer in Veterans is greater than that typically found in the community. For all of these reasons, carrying out this study within the VA through the VA Cooperative Studies Program is the optimal way to determine whether adjuvant chemotherapy will benefit men with high risk prostate cancer.

- Number of Participants With Progression-Free Survival [ Time Frame: Up to 100 months (centralized follow-up) ]The primary objective of this study is to determine whether adding early chemotherapy based on docetaxel plus prednisone compared to standard of care alone reduces disease progression as evidenced by detectable PSA in high risk patients with prostate cancer who have undergone radical prostatectomy.
