Purpose:
We determined whether the clinical and pathological features of hereditary prostate cancer differ from those of sporadic prostate cancer.
Materials And Methods:
We compared the clinical and pathological features of radical prostatectomy specimens from 50 men with and 50 without a family history of prostate cancer who were matched for age and date of surgery.
Results:
Median serum prostate specific antigen concentration was not significantly different in the 2 groups. Mean Gleason score plus or minus standard deviation in the 50 men with sporadic prostate cancer was 6.2 +/- 1 compared to 5.6 +/- 0.9 in those with hereditary disease (p = 0.008). Of the 50 hereditary and 50 sporadic prostate cancers 35 (70%) and 33 (66%), respectively, were pathologically organ confined (p = 0.69). Median percentage of carcinoma within the gland (determined morphometrically) in men with hereditary disease was 11.4 +/- 8.3 compared to 10.9 +/- 8.9 for those with sporadic cancer (p = 0.63).
Conclusions:
In our study population hereditary prostate cancers have significantly lower Gleason scores compared to sporadic carcinomas. Otherwise, there appear to be no substantial clinical or pathological differences.
