Differences in clinical characteristics and disease-free survival for Latino, African American, and non-Latino white men with localized prostate cancer: data from CaPSURE.
BackgroundFew 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.MethodsWe 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.ResultsLatino 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).ConclusionsLatinos are more similar to African Americans on sociodemographic characteristics but more similar to NLW on clinical presentation, treatments received, and DFS

Impact of obesity on prostate cancer recurrence after radical prostatectomy: data from CaPSURE.
ObjectivesTo determine the association between obesity and prostate cancer recurrence after primary treatment with radical prostatectomy.MethodsData were abstracted from CaPSURE, a disease registry of 10,018 men with prostate cancer. We included 2131 men who had undergone radical prostatectomy between 1989 and 2003 and had body mass index (BMI) information available. Recurrence was defined as two consecutive prostate-specific antigen (PSA) levels of 0.2 ng/mL or greater or any second treatment. Patients were risk stratified using the PSA level, Gleason grade, and clinical T stage.ResultsPatients were followed up for a median of 23 months. Of the 2131 patients, 251 (12%) developed recurrence at a median of 13 months (range 1 to 107); 183 (9%) of these men had PSA failure and 68 (3%) received a second treatment. After adjusting for risk group, ethnicity, age, and comorbidities, a significant association was found between an increasing BMI and disease recurrence (P = 0.028). Very obese patients (BMI 35 kg/m2 or more) were 1.69 times more likely to have recurrence relative to men of normal weight (BMI less than 25.0 kg/m2; 95% confidence interval [CI] 1.01 to 2.84). An increasing PSA level (P <0.0001) and Gleason grade (P <0.0001) were also associated with recurrence. Ethnicity was not significantly associated with either BMI or PSA recurrence (P = 0.685 and P = 0.068, respectively).ConclusionsThe results of our study have shown that obesity is an independent predictor of prostate cancer recurrence. Because of the increased comorbidities and greater rates of recurrence, obese individuals undergoing radical prostatectomy need vigilant follow-up care
