Stage at presentation and survival of white and black patients with prostate carcinoma.

BACKGROUND: Black men are known to have a higher incidence and mortality from prostate carcinoma than white men and are more likely to have a more advanced stage or grade of disease diagnosed. METHODS: In a Veterans Administration Medical Center where black and white men have the same eligibility for medical care, the authors reviewed the stage at presentation of 861 consecutive cases of prostate carcinoma diagnosed from 1969-1990. In addition, survival, stratified by race, stage, and grade, was determined on all men in whom prostate cancer was diagnosed from 1969-1985 (525 patients). RESULTS: It was found that 26% of white and 52% of black men with prostate carcinoma presented with Stage D disease. Similar proportions of white and black men with prostate carcinoma presented with Stage D disease between 1969-73 as between 1986-90. The overall survival was poorer for black men because of their higher proportion of Stage D disease, but stratified for grade and stage, survival was similar in both races. CONCLUSIONS: This study suggests that factors other than eligibility for medical care may be responsible for the higher proportion of black men with prostate carcinoma presenting with Stage D prostate carcinoma.

Atypical hyperplasia in prostates of 20 to 40 year old men.

One hundred prostates from 20 to 40 year old men obtained at necropsy were completely sectioned and studied microscopically. Atypical hyperplasia was found in 10 (20%) of 20-29 year old men and in 12 (24%) of 30-40 year old men. The prostates with atypical hyperplasia had similar weights as those without, and the atypical hyperplasia was most common in the lateral lobes of the prostate and near the apex. The atypical hyperplasias were (i) usually mild in degree rather than moderate or severe; (ii) almost equally divided between circumscribed and "infiltrating" lesions; (iii) usually occurred as multiple foci within the same prostate rather than as a single focus of atypical hyperplasia; and (iv) were not associated with inflammation. The finding that atypical hyperplasia is common in men between the ages of 20 and 40 years may be helpful in increasing the understanding of the histopathology of the prostate.
