Background: Prostate cancer is the most common malignancy among men in the western hemisphere, including Trinidad and Tobago. The aim of this study is to describe the epidemiological features of prostate cancer among patients admitted to a tertiary level teaching hospital during 2002 to 2005. We assessed the long term survival of patients with prostate cancer and the epidemiology of the disease.Methods: We reviewed the admissions data for the period 2002-2005. Demographic, clinical and outcomes (survival or death) data were collected and analysed, using SPSS version 16. Statistical analysis included Kaplan-Mier survival analysis, Cox regression models and the log-rank test. A p value of <0.05 was considered statistically significant.Results: Of the 1250 cases reviewed, 242 participants were selected. Patients of African ancestry, older than 60 years and a Gleason score greater than 7 had an increased risk of mortality. Patients with prostate-specific antigen (PSA) ≥100 ng/L had a 3-fold increasedrisk of mortality. Survival rates declined between 2002 and 2005.Conclusion: This is the first study of its kind to demonstrate survival rates among patients with prostate cancer in Trinidad. The following epidemiological features were identified: average age of occurrence of 71 years, ethnic disparity with higher occurrence in African men than all other ethnic groups and a PSA of >100 ng/dL. These features were associated with a 3-fold higher risk of death. A Gleason score of 8 to 10 was also associated with lower survival rates.

330 Background: We evaluated whether the intermediate-risk factors of percentage of positive biopsies (PPB), clinical tumor category, and prostate-specific antigen (PSA) level, in addition to age, were associated with the risk of prostate cancer-specific mortality (PCSM) among men with Gleason 3+4 prostate cancer treated with brachytherapy (BT) alone or BT and a short course of androgen deprivation therapy (ADT). Methods: We conducted a prospective cohort study of 1920 consecutively treated men with Gleason 3+4 adenocarcinoma of the prostate who received BT or BT and a median of 4 months of ADT between 10/14/1997 and 5/28/2013. Separate multivariable Fine and Gray competing risks regression models among men treated with BT or BT and ADT were used to assess whether PPB, cT2b-T2c, and PSA of 10.1-20.0 ng/ml, in addition to age greater than the median of 70 years, were associated with the risk of PCSM after adjustment for comorbidity. Results: After a median follow-up of 7.8 years (interquartile range 5.2-10.4 years), 284 men (14.8%) had died, including 31 (10.9% of deaths) from PC of which 18 (58.1%) and 13 (41.9%) occurred in men treated with BT or BT and ADT, respectively. For men treated with BT alone, increasing PPB, PSA of 10.1-20.0 vs 4.0-10.0 ng/mL, and age >70 vs ≤70 years were significantly associated with an increased risk of PCSM (adjusted hazard ratio [AHR] 1.015 95% confidence interval [CI] 1.000-1.031, P=0.048; AHR 5.55, 95% CI 2.01-15.29, P<0.001; and AHR 3.66, 95% CI 1.16-11.56, P=0.03, respectively). The respective results for men treated with BT and ADT were AHR 1.009, 95% CI 0.987-1.031, P=0.44; AHR 4.17, 95% CI 1.29-13.50, P=0.02; and AHR 3.74, 95% CI 0.87-16.05, P=0.08. The clinical tumor category was not significantly associated with the risk of PCSM. Conclusions: Among men with biopsy Gleason score 3+4 PC, both age >70 years and PSA of 10.1-20.0 ng/ml were significantly associated with an increased risk of PCSM following BT, and adding 4 months of ADT may not be sufficient to mitigate this risk. Advanced imaging and targeted biopsy of suspicious areas should be considered to personalize treatment in order to minimize the risk of PCSM in these men.

198 Background: Radical prostatectomy (RP) and brachytherapy (BT) are widely utilized treatments for favorable-risk prostate cancer (PC). We estimated the risk of PC-specific mortality (PCSM) following RP or BT in men with low- or intermediate-risk PC using prospectively collected data. Methods: The study cohort comprised 5,760 men with low-risk PC (prostate-specific antigen [PSA] level ≤ 10 ng/mL, clinical category T1c or 2a, and Gleason score ≤ 6), and 3,079 men with intermediate-risk PC (PSA level 10-20 ng/mL, clinical T2b or T2c, or Gleason score 7). Competing risks multivariable regression was performed to assess risk of PCSM after RP or BT, adjusting for age, treatment year, cardiovascular comorbidity, and known PC prognostic factors. Results: There was no significant difference in the risk of PCSM among men with low-risk PC (11 vs. 6 deaths: adjusted hazard ratio [AHR], 1.62; 95% CI, 0.59–4.45; P = 0.35) who received BT compared to RP. However among men with intermediate-risk PC, despite significantly shorter median follow-up for men undergoing BT as compared to RP (4.1 vs. 7.2 years, P < 0.001), there was a trend toward an increased risk of PCSM (18 vs. 9 deaths: AHR, 2.30; 95% CI, 0.95–5.58; P = 0.07) for men treated with BT. Conclusions: The risk of PCSM among men with low-risk PC was not significantly different following RP or BT, however there may be a reduced risk of PCSM after RP as compared to BT in men with intermediate-risk PC.

Increased Risk

Prostate cancer is among the most commonly diagnosed cancers among men, ranking second in cancer globally and first in Western countries. There are marked variations in incidence globally, and its incidence must be interpreted in the context of diagnostic intensity and screening. The uptake of prostate-specific antigen screening since the 1990s has led to dramatic increases in incidence in many countries, resulting in an increased proportion of indolent cancers that would never have come to light clinically in the absence of screening. Risk factors differ when studying prostate cancer overall versus advanced disease. Older age, African ancestry, and family history are established risk factors for prostate cancer. Obesity and smoking are not associated with risk overall, but are associated with increased risk of advanced prostate cancer. Several additional lifestyle factors, medications, and dietary factors are now emerging as risk factors for advanced disease.

Background. The aim of the study was to present the oncologic outcomes and to determine the prognostic factors of overall (OS) and cancer-specific survival (CSS) as well as disease-progression-free survival (DPFS) after surgery for pT3b prostate cancer. Materials and methods. In 2002–2007, a pT3b stage after radical prostatectomy was detected in 56 patients. Patients were divided into groups according to the prostate-specific antigen (PSA) level (20 ng/ml), lymph nodes status (N0 vs. Nx vs. N1) and the Gleason score (6–7 vs. 8–10). The Kaplan–Meier analysis was used to calculate OS, CSS and DPFS. The Cox regression was used to identify the predictive factors of survival. Results. Five-year OS, CSS and DPFS rates were 75.1%, 79.6% and 79.3%, respectively. The survival was significantly different when comparing the Gleason 6–7 and 8–10 groups. The 5-year OS, CSS and DPFS were 91.2% vs. 48.6%, 97.1% vs. 51.1% and 93.8 vs. 51.1%, respectively. There was no difference in survival among the groups with a different PSA level. The OS and CSS but not DPFS were significantly different when comparing the N0 and N1 groups. The 5-year OS and CSS was 84.4% vs. 37.5% and 87.3% vs. 47.6%, respectively. The specimen Gleason score was a significant predictor of OS and CSS. The risk of death increased up to 4-fold when a Gleason score 8–10 was present at the final pathology. Conclusions. Radical prostatectomy may offer acceptable CSS, DPFS and OS rates in pT3b PCa. However, outcomes in patients with N1 and specimen Gleason ≥8 were significantly worse, suggesting the need of multimodality treatment in such cases.

e562 Background: We estimated the natural history and predictive factors of oncological outcomes in patients with prostate cancer (PCa) after radical prostatectomy (RP). Methods: In this retrospective study, we reviewed the clinical and pathological records of 1083 PCa patients who underwent RP and bilateral pelvic lymphadenectomy with or without neoadjuvant therapy between July 1996 and December 2014 at Hirosaki University. All patients were followed-up by assessing serum prostate-specific antigen (PSA) and testosterone levels every 3 months for 5 years and every 6 months thereafter. The endpoint was the oncological outcomes after surgery. Univariate analyses were performed using the Kaplan-Meier and log-rank methods, and the multivariate analysis was performed using a Cox proportional hazard model. Results: The 5-year and 10-year overall survival rates were 98.5 % and 92.0 %, respectively. At the end of the study, 226 patients (20.8%) showed biochemical recurrence and 28 patients (2.6%) had developed castration-resistant Pca (CRPC). The patients with CRPC were significantly poor prognosis compared with those without CRPC (P < 0.01). On multivariate analysis, although preoperative variables were no significant differences, only CRPC was significantly associated with OS. Conclusions: RP was shown to provide excellent long-term survival with OS at 10 years. In addition, a small proportion of the patients treated with RP had CRPC and died of Pca within 10 years. Development to castration resistant status may have critical impact on OS.

Purpose Active surveillance is now considered a viable treatment option for men with low-risk prostate cancer. However, little is known regarding changes in Gleason grade on serial biopsies over an extended period of time. Patients and Methods Men diagnosed with prostate cancer between 1998 and 2009 who elected active surveillance as initial treatment, with 6 or more months of follow-up and a minimum of six cores at biopsy, were included in analysis. Upgrading and downgrading were defined as an increase or decrease in primary or secondary Gleason score. Means and frequency tables were used to describe patient characteristics, and treatment-free survival rates were determined by life-table product limit estimates. Results Three hundred seventy-seven men met inclusion criteria. Mean age at diagnosis was 61.9 years. Fifty-three percent of men had prostate-specific antigen of 6 ng/mL or less, and 94% had Gleason score of 6 or less. A majority of men were cT1 (62%), had less than 33% of biopsy cores involved (80%), and were low risk (77%) at diagnosis. Median number of cores taken at diagnostic biopsy was 13, mean time to follow-up was 18.5 months, and 29% of men had three or more repeat biopsies. Overall, 34% (129 men) were found to have an increase in Gleason grade. The majority of men who experienced an upgrade (81%) did so by their second repeat biopsy. Conclusion A proportion of men experience an upgrade in Gleason score while undergoing active surveillance. Men who experience early upgrading likely represent initial sampling error, whereas later upgrading may reflect tumor dedifferentiation.

Background and Purpose. Life expectancy data could identify men with favorable post-radiation prostate-specific antigen (PSA) failure kinetics unlikely to require androgen deprivation therapy (ADT).Materials and Methods. Of 206 men with unfavorable-risk prostate cancer in a randomized trial of radiation versus radiation and ADT, 53 experienced a PSA failure and were followed without salvage ADT. Comorbidity, age and established prognostic factors were assessed for relationship to death using Cox regression analyses.Results. The median age at failure, interval to PSA failure, and PSA doubling time were 76.6 years (interquartile range [IQR]: 71.8–79.3), 49.1 months (IQR: 37.7–87.4), and 25 months (IQR: 13.1–42.8), respectively. After a median follow up of 4.0 years following PSA failure, 45% of men had died, none from prostate cancer and no one had developed metastases. Both increasing age at PSA failure (HR: 1.14; 95% CI: 1.03–1.25;P=0.008) and the presence of moderate to severe comorbidity (HR: 12.5; 95% CI: 3.81–41.0;P<0.001) were significantly associated with an increased risk of death.Conclusions. Men over the age of 76 with significant comorbidity and a PSA doubling time >2 years following post-radiation PSA failure appear to be good candidates for observation without ADT intervention.

Therapeutic Decision Making

Older men are more likely to have advanced prostate cancer at time of their diagnosis, but whether prostate tumors are inherently (biologically) more aggressive with advancing age is uncertain. To address this gap in knowledge, we analyzed data from veterans (n=971) diagnosed with prostate cancer during 1991–1995. Factors included age, detection of prostate cancer by screening, prostate-specific antigen (PSA) level, anatomic stage, and Gleason score. Information on molecular markers obtained from immunohistochemical staining of prostate tissue, included B cell lymphoma-2 (bcl-2), p53, and microvessel density (MVD), each having a previously documented association with disease progression and increased risk of prostate cancer death. We first examined the bivariate association of demographic, clinical, and molecular factors with age, and found evidence that race, screening status, Gleason score, PSA, bcl-2, p53, and MVD varied across categories of age in this study population. After further characterizing the association between age and Gleason score, we used logistic regression to examine the association between age and molecular markers—accounting for race, screening status, PSA, and Gleason score. Comparing men older than 80 years to those younger than 70 years, adjusted ORs and 95% CIs were 1.89 (0.73 to 4.92), 1.91 (1.05 to 3.46), and 2.00 (1.06 to 3.78), for positive bcl-2, p53, and MVD markers, respectively; no statistically significant associations were found for men 70–79 years old, compared with men younger than 70 years. These novel findings suggest that very elderly men often present with biologically aggressive prostate cancer; the results also have potential implications for therapeutic decision-making.

ObjectiveGiven a man’s current prostate- specific antigen (PSA) level, age and family history of prostate cancer, what are the benefits (decreased risk of higher Gleason score [GS] cancer at diagnosis) and harms (increased risk of false-positive biopsy recommendation) of waiting 1, 2, 3, 4 or 5–8 years until the next PSA test?DesignProspective cohort.SettingAll PSA tested men in Stockholm, Sweden, between 2003 and 2015.ParticipantsMen aged 50–74 years with at least two PSA tests between 2003 and 2015 (n=174 636).Main outcome measuresLog-binomial regression to calculate the risk ratio (RR) of GS ≥7 and GS 6 versus benign outcome at prostate biopsy and 12-year cumulative probability of experiencing a false-positive biopsy by testing interval, age, PSA level and first-degree family history.ResultsMen with PSA ≤1 ng/mL had low risk of GS ≥7 prostate cancer irrespective of testing interval; <3% had a PSA >3 at the next testing occasion, and of the 663 men biopsied after the next PSA test only 32 (5%) had GS ≥7 cancer. Men with PSA >1 ng/mL had increased risk of being diagnosed with GS ≥7 prostate cancer when screened with longer than annual intervals (RRs ranged from 1.4 to 3.2 depending on PSA level and testing interval). The results were consistent across age groups and family history status. This benefit needs to be balanced against the increased risk for false-positive biopsy recommendation with shorter testing intervals (twofold for annual vs biennial and threefold for annual vs triennial).ConclusionsMen aged 50–74 years with PSA ≤1 ng/mL can wait 3–4 years before having a new PSA test. For men with PSA >1 ng/mL, we observed an increased risk of being diagnosed with GS ≥7 prostate cancer with longer than annual testing intervals. This benefit needs to be balanced against the markedly increased risks for false-positive biopsy recommendations with shorter testing intervals recommendations.

PurposeWe examined whether time-dependent continuous prostate-specific antigen (PSA) velocity at recurrence was associated with all cause mortality (ACM) adjusting for comorbidity levels among men treated with definitive radiation therapy (RT) alone with or without androgen suppression therapy (AST) in the setting of a randomized controlled trial.Patients and MethodsFrom 1995 to 2001, 206 men with localized, unfavorable prostate cancer were randomly assigned to receive RT alone or RT and AST combined. Cox multivariate regression analysis was performed to evaluate the relationship between PSA velocity at recurrence and ACM, adjusting for known prostate cancer prognostic factors, including Adult Comorbidity Evaluation 27 comorbidity level.ResultsWith a median follow-up of 8.4 years, 89 biochemical recurrences and 74 ACM deaths occurred. Among all patients, higher PSA velocity was associated with increased ACM (hazard ratio [HR], 1.47; 95% CI, 1.07 to 1.44; P < .001) after adjusting for age, treatment arm, comorbidity score, and salvage AST. For 89 patients with biochemical recurrence, increasing PSA velocity at recurrence (HR, 1.60; 95% CI, 1.23 to 2.09; P ≤ .001) and moderate to severe comorbidity score (HR, 7.94; 95% CI, 1.55 to 40.52; P = .01) were associated with increased ACM. PSA velocity at recurrence was associated with significantly higher risk of ACM among patients with no or minimal comorbidity (P < .001), but not moderate to severe comorbidity (P = .12).ConclusionRapid PSA velocity at recurrence is significantly associated with an increased risk of ACM among patients with no or minimal comorbidity but not moderate to severe comorbidity. These findings support judicious use of salvage AST, particularly in men with moderate to severe comorbidities, where prospective surveillance protocols are needed.
