Prevalence, treatment modalities and prognosis of familial prostate cancer in a screened population

Purpose: A family history of prostate cancer is an important risk factor for this disease. The clinical presentation and prognosis of familial disease remain uncertain. In this study these entities are evaluated in the first and second rounds of a screening program in The Netherlands. Materials and Methods: Of all men randomized in the Rotterdam section of the ERSPC, 19,970 men were eligible for screening. Information regarding the family history was obtained by a self-administered questionnaire at baseline. Results: In the prevalence screen the cancer detection rate in 1,364 men (7.1%) with a positive family history was 7.7% (106 cancers in 1,364 screened men with a positive family history) while the positive predictive value of the biopsies was 32.2% (154 cancers of 532 biopsies). In 12,803 sporadic cases the detection rate was 4.7% and the positive predictive value was 23.6% (p <0.0001 and 0.003, RR 1.63). No clinicopathological differences were found in the 1,559 men diagnosed in the first and second rounds. The overall biochemical-free survival rate after a mean followup of 56.8 months (range 0 to 129.9) was 76.8%, and was not significantly different in familial and sporadic cases (p = 0.840). These findings were consistent for the specific treatment modalities as well. Conclusions: Although screened men 55 to 75 years old with a father or a brother having prostate cancer themselves are at a substantially greater risk for the disease, the clinical presentation, treatment modalities and prognosis by biochemical progression are not different compared to sporadic cases.
