Prostate cancer in Asian men

Area of Science:

• Oncology
• Epidemiology
• Public Health

Background:

• Prostate cancer incidence and mortality are increasing in native Asian populations.
• Rates are lower than in Asian-American and other American cohorts, with potential influences from genetics, diet, and screening.
• Disparities in screening access may be a significant factor in observed epidemiological differences.

Purpose of the Study:

• To analyze the epidemiological variations in prostate cancer across Asian populations.
• To investigate the contributing factors, including screening, genetics, and environment, to these variations.
• To propose individualized management strategies for prostate cancer in Asian countries.

Main Methods:

• Comparative analysis of prostate cancer incidence and mortality data across different Asian and American cohorts.
• Evaluation of potential contributing factors such as genetic predispositions, dietary patterns (e.g., Western diet), and access to Prostate-Specific Antigen (PSA) screening.
• Assessment of the prevalence of metastatic prostate cancer in various populations.

Main Results:

• Native Asian populations show increasing prostate cancer rates, yet lower than Asian-American and Western cohorts.
• Lower exposure to PSA screening in Asian individuals is a potential key factor, alongside genetic and environmental influences.
• A higher proportion of metastatic prostate cancer is observed in Asian countries compared to Western populations, even in developed Asian nations.

Conclusions:

• Variations in prostate cancer epidemiology among native Asian populations may be linked to differences in access to PSA testing, urology clinics, and therapies.
• Individualized prostate cancer screening and treatment strategies are essential for Asian countries, considering specific epidemiological features and socioeconomic status.
• Addressing disparities in screening and treatment access is crucial for improving prostate cancer outcomes in Asia.
