N2 - This study evaluated the relationship between caffeinated and decaffeinated coffee and prostate cancer (CaP) aggressiveness using data from a population-based incident CaP study within the North Carolina-Louisiana Prostate Cancer Project (PCaP). Classification of CaP aggressiveness at diagnosis was based on clinical criteria for 1,049 African-American (AA) and 1,083 Caucasian-American (CA) research subjects. Coffee consumption was measured using a modified NCI Dietary History Questionnaire. No significant associations were found between CaP aggressiveness and consumption of either caffeinated or decaffeinated coffee. The OR for high aggressive CaP among consumers of more than 4 cups per day was 0.92 (95%CI = 0.61, 1.39), compared to non-coffee-drinkers. Results stratified by race found no significant associations and no noticeable trends in either AAs (P for trend = 0. 62) or CAs (P for trend = 0.42). In contrast to a recent report on a select population that has less complete information on CaP aggressiveness suggesting that coffee prevents aggressive CaP, this rapid case ascertainment population-based study, in a biracial population with differing risks of CaP did not demonstrate a protective relationship between high coffee consumption and risk of high aggressive CaP.
