    Abstract:
    BACKGROUND: Few studies of ethnicity and prostate cancer have included Latino men in analyses of baseline clinical characteristics, treatment selection, and disease-free survival (DFS). The present study examines the impact of Latino ethnicity on these parameters in a large, multiinstitutional database of men with prostate cancer. METHODS: We compared baseline disease characteristics and clinical outcomes for Latino (N = 138), non-Latino White (NLW, N = 5619), and African-American (AA, N = 608) men with localized prostate cancer by using chi-square and ANOVA for baseline variables and survival analysis to examine differences in time to recurrence. RESULTS: Latino men resembled AA men more than NLW on sociodemographic characteristics. AA men had higher Gleason scores and prostate-specific antigen (PSA) at diagnosis than Latino or NLW men (both P < 0.01). 10% of both Latino and AA men presented with advanced disease (T3b/T4/N+/M+) versus 4% of NLW (P < 0.01). Latino men did not receive different treatments than NLW or AA men after controlling for clinical and demographic factors; however, AA men were more likely to receive external beam radiation (OR = 1.51, 95% confidence interval [CI] = 0.99-2.31) and hormone treatment (OR = 1.56, 95% CI = 1.05-2.32) then NLW men. For prostatectomy patients, 3-year actuarial DFS rates were 83% for NLW men and 86% for Latino men versus 69% for AA men (P < 0.01). After controlling for clinical and sociodemographic variables, AA men were somewhat more likely than NLW to experience disease recurrence after radical prostatectomy (RP) (HR = 1.38, 95% CI = 0.98-1.94, P = 0.06). CONCLUSIONS: Latinos are more similar to African Americans on sociodemographic characteristics but more similar to NLW on clinical presentation, treatments received, and DFS.
