The association between family history of prostate cancer and development of prostate cancer among Korean population A prospective cohort study using KoGES data

This study aimed to assess the impact of family history (FH) on prostate cancer (PCa) development among a general Korean population. We conducted a prospective cohort study based on the registry records of 211,789 participants in the database of the Korean Genome and Epidemiology Study from 2001 to 2013. A total of 69,693 men with appropriate records were evaluated by being categorizing into 2 groups; a PCa group (100) and control group (69,593). FH of PCa was also categorized as FH of total, father, or brother. Odds ratios (ORs) of PCa development were calculated by using stratified logistic regression models. The adjusted OR of PCa history of father was 27.7 (95% confidence interval [CI] = 9.7-79.2, P < .001) in PCa patients compared to control, and that of PCa history of brother was 15.8 (95% CI = 3.6-69.6, P < .001). Among the adjusted variables, age (OR, 1.17; 95% CI, 1.14-1.21; P < .001), and hyperlipidemia (OR, 2.25; CI, 1.32-3.84; P = .003) were also identified as significant predictors of PCa development. There was no difference in the impact of FH on PCa development between different age groups at PCa diagnosis (<60 vs >= 60 years). To our knowledge, this study represents the first prospective cohort study based on the registry data of a Korean population showing the significance of FH on PCa development. Additionally, the effect of FH on the early onset of PCa has not been confirmed in our analysis.

Automated summary

This study found that a family history of prostate cancer in fathers posed a higher risk for patients compared to a family history in brothers. Additionally, age and hyperlipidemia were significant predictors of prostate cancer development.
