Purpose: Men with a family history of prostate cancer are at higher risk for prostate cancer. There are conflicting data regarding the impact of hereditary forms of prostate cancer on long-term outcomes after radical prostatectomy. We examined the impact of familial and hereditary prostate cancer treatment in the prostate specific antigen era.
Materials and methods: Patients who underwent radical prostatectomy for prostate cancer from 1987 to 1997 were surveyed (3,560 responders) to determine the family history of prostate cancer. Patients were categorized as having familial prostate cancer if they had at least 1 first-degree relative with prostate cancer. Hereditary prostate cancer was defined as nuclear families with 3 cases of prostate cancer, families with prostate cancer in each of 3 generations and families with 2 men diagnosed before age 55 years. Sporadic prostate cancer was defined as patients with no family history. Clinical and pathological features, and long-term outcome measures, including biochemical recurrence-free, systemic progression-free and cancer specific survival, were compared among patients with familial, hereditary and sporadic prostate cancer.
Results: A total of 865 and 133 patients were categorized as having familial prostate cancer and hereditary prostate cancer, respectively. Preoperatively prostate specific antigen was higher in patients with hereditary prostate cancer than in the other 2 groups (p = 0.04). Ten-year biochemical progression-free, systemic progression-free and cancer specific survival were equivalent.
Conclusions: Except for preoperative prostate specific antigen, clinicopathological features and long-term oncological outcomes are equivalent after radical prostatectomy in patients with familial, hereditary and sporadic prostate cancer.
