[Mass screening for detection of prostatic carcinoma]

Area of Science:

• Oncology
• Urology
• Public Health

Context:

• Breast cancer screening success fuels global advocacy for similar approaches.
• Concerns exist regarding overdiagnosis and overtreatment in cancer screening programs.
• The definitive benefit of early prostate cancer detection is still under investigation.

Purpose:

• To evaluate the necessity and efficacy of prostate cancer screening.
• To address the lack of pretreatment prognostic factors for distinguishing aggressive from indolent prostate cancers.
• To determine if prostate cancer screening reduces mortality and improves quality of life.

Summary:

• Active screening for breast cancer is widely accepted due to positive outcomes.
• Prostate cancer screening's value in detecting asymptomatic disease is uncertain.
• Identifying prognostic factors is crucial for managing prostate cancer effectively.

Impact:

• Randomized studies are essential to prove the mortality benefits of prostate cancer screening.
• Ongoing research in the USA, Canada, and Europe aims to resolve screening efficacy.
• Clarifying screening benefits is vital for patient outcomes and healthcare resource allocation.
