Study Characteristics

Objectives

The primary objective of this study is to determine which of two strategies is superior for the management of clinically localized prostate cancer

  • Radical prostatectomy with early aggressive intervention for disease persistence or recurrence
  • Expectant management with reservation of therapy for palliative treatment of symptomatic or metastatic disease progression

Era of Service

All

Population

Male patients diagnosed with or treated for early-stage (I/II) prostate cancer within the Department of Veterans Affairs (VA) health care system.

Study Design

Randomized controlled clinical trial

Intervention

  • Intervention: Radical prostatectomy (surgical removal of the prostate)
  • No intervention: Expectant management (closely watching, waiting, and treating symptoms if cancer progresses)

Time Period

November 1994 – January 2010

Setting

National

N

731 (expectant management n=367, radical prostatectomy n =364)

Response Rate

All-cause Mortality (as of 1/31/10):

  • Expectant Management:  183 deaths in 367 randomized (49.9%)
  • Radical Prostatectomy: 171 deaths in 364 randomized (47.0%)

Recruitment Method

13,022 men with prostate cancer were screened at 44 VA and 8 National Cancer Institute sites for potential enrollment. 5,023 met initial age, comorbidity, and disease eligibility criteria, and a total of 731 men agreed to participate and were randomized.

Compensation

None

Data Collected
