Yield of prostate cancer screening at a community based clinic in Saudi Arabia.

Objectives: To estimate the incidence and prevalence of prostate cancer in Saudi Arabia.
Methods: This is a retrospective cohort study including male patients aged 40 years and over. The prostate-specific antigen screening tests were carried out in a community-based clinic affiliated with King Faisal Specialist Hospital and Research Centre, Riyadh, Kingdom of Saudi Arabia between September 2002 and December 2016.
Results: A total of 2,160 male patients were included in the study. Of these, 1,521 (70%) were Saudi nationals and 639 (30%) were non-Saudi nationals. A total of 108 (5%) patients underwent a prostate biopsy. The biopsy results confirmed that 31 (2%) Saudi patients and 6 (0.93%) non-Saudi patients had prostate adenocarcinoma. The age-standardized incidence rate of prostate cancer in the Saudi male population is 70 per 100,000 males. Nearly two-thirds (71%) of the Saudi patients' prostate cancer was found to be in the early stages. Conclusion: The prevalence of prostate cancer in the Saudi male population is higher than that reported by the Saudi Cancer Registry; however, it is low compared with prevalences in developed countries. The mortality rate is also very low. Prostate-specific antigen screening in Saudi Arabia should not be carried out routinely; instead, it should only be carried out on an individual basis.
