PURPOSE: There are conflicting reports concerning whether prostate cancer in families with multiple affected members has different clinical and pathological features than sporadic cases. In our study we compared the clinical characteristics, pathological outcomes and the 7-year biochemical progression-free rate in patients with apparent sporadic prostate cancer, affected sibling pairs, families with multiple affected members and families meeting the Johns Hopkins criteria for hereditary prostate cancer. MATERIALS AND METHODS: From 1983 to 2003, 3,478 men underwent radical retropubic prostatectomy by a single surgeon (WJC). Of these men 1,186 reported family history status. We compared age at surgery, prostate specific antigen at diagnosis, pathological tumor stage, Gleason score, tumor characteristics and 7-year biochemical progression-free survival rates in the groups using chi-square, 1-way ANOVA or Cox proportional hazards regression analysis. RESULTS: The 7-year biochemical progression-free survival rates were 81% for sporadic cases, 71% for sibling pairs, 72% for hereditary cases and 81% for high density family members (p = 0.3). Of the clinical and pathological features examined only age (p <0.0001) and positive surgical margin rate (p = 0.03) were significantly different among groups. CONCLUSIONS: In our study population clinicopathological features and progression-free survival are similar between sporadic and familial prostate cancer cases. The sibling pairs had a trend toward less favorable tumor features and progression-free survival, but the difference was not statistically significant.
