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<0.001).
A family history of prostate cancer in Korean men was a significant factor for predicting prostate cancer. Moreover, significant differences in the aggressive features of the disease were identified between patients with and without a family history.
