Mass screening for prostate cancer in Korea: a population based study

Area of Science:

• Urology
• Oncology
• Public Health

Background:

• Prostate cancer screening is crucial for early detection.
• Population-based screening can identify cancer in asymptomatic individuals.
• Understanding cancer detection rates in specific demographics is essential for public health strategies.

Purpose of the Study:

• To determine the prostate cancer detection rate in Korean men aged 55 and older using population-based mass screening.
• To analyze prostate-specific antigen (PSA) levels and cancer detection rates based on age and region.
• To establish a baseline for future prostate cancer surveillance in South Korea.

Main Methods:

• Serum PSA levels were measured in 3,943 Korean men aged 55 or older across three regions.
• A PSA threshold of 3.0 ng/ml was used to recommend 12-site transrectal biopsy.
• Cancer detection rates were analyzed by age groups, PSA levels, and biopsy results.

Main Results:

• The overall estimated prostate cancer detection rate was 3.36% in men aged 55 and older.
• PSA levels and cancer detection rates significantly increased with age.
• No significant regional differences in PSA levels or detection rates were observed.
• Higher PSA levels correlated with increased cancer detection rates (12.3% at 3.0-4.0 ng/ml to 64.1% at >10.0 ng/ml).

Conclusions:

• The estimated prostate cancer detection rate of 3.36% in Korean men aged 55 and older warrants further investigation.
• Repeat screening and continued surveillance are recommended to ascertain the clinical significance of these findings.
• The study highlights the importance of age-specific screening protocols and PSA level stratification for prostate cancer detection.
