Familial Prostate Cancer in Three Brothers

We treated a family of 3 brothers with prostate cancer, which is the first report of familial prostate cancer in Korea. Prostate cancer was diagnosed in the first brother with a prostate-specific antigen (PSA) level of 12.70 ng/ml of at the age of 68 years. He underwent a radical retropubic prostatectomy (RRP); the cancer was pathologically staged to T_2cN₁M_o. He received adjuvant hormonal therapy postoperatively. Three years later, prostate cancer was diagnosed in the third brother at the age of 61 years with a high PSA level of 4.45 ng/ml. He underwent RRP, which revealed the pathological stage to be T_2cN₀M₀. Three months later, the second brother, who had visited our hospital for lower urinary tract symptoms and for a PSA screening test was diagnosed with prostate cancer at the age of 60 years (PSA level of 3.96 ng/ml). He also underwent RRP, and his cancer was staged pathologically as T_2cN₀M₀.
