Area of Science:

  • Oncology
  • Preventive Medicine
  • Clinical Trials

Background:

  • Prostate cancer is a highly prevalent genitourinary malignancy.
  • Prevention research is crucial for managing widespread cancers.
  • The Prostate Cancer Prevention Trial (PCPT) was designed to investigate interventions.

Purpose of the Study:

  • To present the rationale, design, and status of the PCPT.
  • To evaluate the efficacy of finasteride in preventing prostate cancer.
  • To address potential biases in prostate cancer detection.

Main Methods:

  • A large-scale, randomized prevention study involving 18,882 men.
  • Use of finasteride as the intervention.
  • Planned end-of-study biopsies for all participants to mitigate detection bias.

Main Results:

  • The study was terminated early by the Data and Safety Monitoring Committee.
  • Finasteride showed a 24.8% reduction in prostate cancer incidence.
  • Significant accrual of participants was achieved over a 3-year period.

Conclusions:

  • The PCPT's success underscores the potential of large prospective studies in cancer prevention.
  • Positive trial results support increased focus on prevention strategies for genitourinary cancers.
  • Further research into cancer prevention is warranted.
