Family history, race, and prostate cancer.

225Background: African American (AA) race and family history (FH) of prostate cancer (PCa) increase the incidence and mortality of PCa. The goal of this study was to assess and compare FH in AA and Caucasian (C) men. Methods: During June 2015 through September 2016, 338 men with prostate cancer had FH collected at Tulane Cancer Center (C = 266 and AA = 72). A FH was defined as ≥ 1 1st degree relative with PCa and/or ≥ 2 affected 2nd/3rddegree relatives. Documented clinical factors were age at diagnosis (dx), Gleason score, incidence of radical prostatectomy (RP), and presence of metastases (at any time). Chi-square and Mann-Whitney U tests were performed to identify potential clinical correlates with regard to FH and race. Results: For demographics see table below. On average, men with a FH of PCa (n = 110) had a median age at dx of 59.6 as compared to those without a FH of PCa (n = 151) (median age at dx = 63.0). Overall FH patients (pts) were younger at dx (p = 0.00046). FH had a particularly impactful ...
