1. Selection of screening method
It is well documented that the most effective way to maximize detection of early curable prostate cancer is to perform annual serum prostate-specific antigen (PSA), prostate finger examination (DRE) and transrectal ultrasound (TRUS) in all men over 45 years of age. Although the highest number of prostate cancer cases are detected by performing these three tests simultaneously, this approach requires a large number of professionals and is not easily accepted by the asymptomatic general population, so a stepwise planning is reasonable in terms of affordability and acceptability. The American Cancer Society recommends transrectal examinations and serum PSA and fPSA measurements as the “first-line” screening methods, and transrectal ultrasonography and ultrasound-guided multi-point puncture biopsy as the “second-line” screening methods. 2.Screening age range
The screening range is appropriate for men aged 50 to 70 years old, and asymptomatic people under 50 years old and over 75 years old with poor general condition are not included in the screening, especially the latter cannot be treated radically even if the diagnosis is positive. 3, the time of screening is generally considered appropriate to check once a year. 4.Screening procedure
Participants should first fill out a family history of prostate cancer, urological history and current symptoms and then undergo transrectal finger examination and determination of serum PSA and fPSA. TRUS (transrectal prostate ultrasound) and ultrasound-guided multi-point puncture biopsy will be performed only if the serum PSA and fPSA are abnormal and/or the rectal finger examination is problematic.
