Study Suggests Radical Prostatectomy Does Not Significantly Reduce All-Cause or Prostate-Cancer Mortality


BACKGROUND:
The treatment of early-stage prostate cancer remains controversial, especially for tumors detected by means of prostate-specific antigen (PSA) testing. Moreover, although the lifetime risk of receiving a diagnosis of prostate cancer is about 17%, the risk of dying from the disease is approximately 3%, suggesting that conservative management may be appropriate for many men. This randomized trial compared radical prostatectomy with observation in 731 men who had received a diagnosis of clinically localized prostate cancer in the early era of PSA testing. Enrollment of patients in this study began in 11/94 and ended in 1/02, with follow-up through 1/10. Patients were recruited from 44 VAMCs and 8 National Cancer Institute (NCI) sites. Study visits were scheduled every six months for a minimum of 8 years and a maximum of 15 years, or until the patient died. Investigators analyzed death from any cause, death from prostate cancer or treatment (with death from other causes treated as a competing risk), and bone metastases.

FINDINGS:

  • Among men with localized prostate cancer, which was detected during the early era of PSA testing, radical prostatectomy did not significantly reduce all-cause or prostate cancer mortality, as compared with observation, through at least 12 years. During the median follow-up of 10 years, 171 of 364 men (47%) assigned to radical prostatectomy died, compared with 183 of 367 men (50%) that were assigned to observation. Among men assigned to radical prostatectomy, 21 (6%) died from prostate cancer or treatment compared with 31 men (8%) assigned to observation.
  • Sub-group analyses suggest that surgery might reduce mortality among men with higher PSA values and possibly among men with higher-risk tumors (absolute reductions in mortality between 7% and 13%), but not among men with PSA levels of 10 ng per milliliter or less, or among men with low-risk tumors.
  • The effect of treatment on all-cause and prostate cancer mortality did not differ according to the patient's age, race, co-existing conditions, or self-reported performance status.
  • Peri-operative complications during the first 30 days after surgery occurred in 21% of men who underwent a radical prostatectomy, and included one death.

NOTE:
The authors note that their study was conducted in the early era of PSA testing. Current practices of performing repeated PSA testing, using a lower threshold for biopsy, obtaining more tissue-biopsy cores, and performing a repeat biopsy after initially negative findings increase the detection of smaller-volume indolent cancers. Along with histologic upgrading, these factors increase the likelihood of over-diagnosis and over-treatment. As a result, potential benefits of prostatectomy would likely be even smaller for men with a current diagnosis of prostate cancer.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
