The incidence of prostate cancer in Iran: results of a population-based cancer registry.

BACKGROUND Little is known about the epidemiology of prostate cancer in Iranian men. We carried out an active prostate cancer surveillance program in five provinces of Iran. METHODS Data used in this study were obtained from population-based cancer registries between 1996 and 2000. RESULTS The age-standardized incidence rate of prostate carcinoma in the five provinces was 5.1 per 100,000 person-years. No significant difference was seen in the age-standardized incidence rate of prostate cancer within the provinces studied. The mean+/-SD age of patients with prostate cancer was 67+/-13.5 years. CONCLUSION The incidence of prostate cancer in Iran is very low as compared to the Western countries. This can partly be explained by lack of nationwide screening program, younger age structure and quality of cancer registration system in Iran.
