The association of family history of prostate cancer with the diagnosis of clinically significant prostate cancer in Korean population

The impact of family history on the diagnosis of the prostate cancer among Asian population remains controversial. We evaluated whether a positive family history of the prostate cancer in Korean men is associated with the diagnosis and aggressiveness of the prostate cancer. Patients who underwent a transrectal ultrasound-guided prostate biopsy from March 2015 to September 2017 were evaluated. Information on family history was obtained via a self-administered questionnaire. The presence of prostate cancer and clinically significant prostate cancer (Gleason score ≥7) was evaluated according to the presence of a family history. Of 602 patients (median age, 68.3 years; median prostate-specific antigen level, 6.28 ng/mL), 41 (6.8%) patients had a family history of prostate cancer. Family history was a significant factor for detecting prostate cancer (odds ratio [OR], 2.99; 95% confidence interval [CI], 1.330-6.704; p=0.008). In multivariate analysis for predicting clinically significant prostate cancer, family history was a significant predictor (OR, 6.32; 95% CI; 2.790-14.298; p
