AbstractBackground: Prostate cancer clinical stage T2 (cT2) subclassifications, as determined by digital rectal examination (DRE), are a historic method of staging prostate cancer. However, given the potential discomfort associated with prostate examination and the wide availability of other prognostic tests, the necessity of DRE is uncertain. This study sought to determine the prognostic value of the prostate cancer cT2 subclassifications in a contemporary cohort of patients. Methods: The National Cancer Database was used to identify a cohort of men with high-risk clinical T2N0M0 prostate cancer treated with external-beam radiotherapy and androgen deprivation therapies ± surgery from 2004 to 2010. We assessed overall survival from a landmark time of 10 months using Kaplan-Meier and log-rank test analysis. A multivariate proportional hazards model was used to estimate the simultaneous effects of multiple factors, including cT2 subclassification and other well-established prognostic indicators of overall survival in prostate cancer. Results: A total of 5,291 men were included in the final analysis, with a median follow-up of 5.4 years. The cT2a, cT2b, and cT2c subclassifications demonstrated increasing hazard ratios of 1.00 (reference), 1.25 (95% CI, 1.07–1.45; P=.0046), and 1.43 (95% CI, 1.25–1.63; P<.0001), respectively, reflecting a higher probability of death with each incremental increase in cT2 subclassification. This finding was independent of other known prognostic variables on multivariate analysis. Conclusions: Results show that cT2 subclassifications had independent prognostic value in a large and contemporary cohort of men. cT2 classification remains an important, low-cost prognostic tool for men with prostatic adenocarcinoma. The clinical relevance of this test should be appreciated and accounted for by providers treating prostate adenocarcinoma.

27 Background: The correlation between PDE5-I use to improve erectile function post RP and BCRF and OS on prostate cancer (PCa) patients (pts) has yielded conflicting results among prior retrospective cohort studies (Michl, 2015). Recent data suggests that these drugs may have an impact on immunity that may explain possible benefits. This study’s purpose was to determine whether PDE5-I use affects BCRF and OS for pts treated with RP for PCa. Methods: This is an IRB approved retrospective cohort study analyzing a subset of pts consented to the SPORE in PCa at Northwestern University’s Lurie Cancer Center. Inclusion criteria included men diagnosed with PCa and treated with RP with curative intent between 2003-2015. Study population (n = 2,410) showed 834 (34.6%) received a PDE5-I post-RP, while 1,576 (65.4%) did not. Pts were grouped based on PDE5-I use and no PDE5-I use after RP. A PDE5-I user must have filled at least 2 prescriptions or completed at least 2 inpatient administrations of a PDE5-I. Continuous variables were summarized by descriptive statistics and differences between groups were assessed via the Wilcoxon rank sum test. Categorical variables were reported by frequencies and percentages and compared via Fisher’s exact test. OS and BCRF survival were summarized for 10-yr rates using Kaplan-Meier estimates. The difference in BCRF and OS between groups was evaluated via log-rank test. Results: Mean age at RP was 60, and 90.95 % were Caucasian. Except for pairwise comparisons for significance of Gleason 3+3 vs. 3+4 histology with higher prevalence of 3+4 in the PDE5-I group (p = 0.0004) and a higher percent of clinical stage T2b-c than T2a in the no PDE5-I group (p = 0.01), no differences were noted in demographics. The 10-yr BCRF survival among PDE5-I users was 92.53% compared to 79.63% among non-users after RP (p < 0.0001). The 10-yr OS rate among PDE5-I users was 97.22% compared to 92.69% among non-users (p = 0.008). Conclusions: This retrospective analysis suggests that PDE5-I use improves biochemical recurrence free survival and overall survival in pts treated with RP for PCa.

Background. Prostate cancer is the second most common cancer among men globally. A few studies that have been done in Uganda on survival of patients with prostate cancer indicate that, the overall survival of patients with prostate cancer in Uganda is poor. The aim of this study was to determine the 3-year overall survival rate of a cohort of patients with prostate cancer residing in Kyadondo County who were diagnosed from 2012 to 2014. The secondary objective was to correlate the overall survival with the clinicopathological prognostic factors. Materials and Methods. This was a retrospective cohort study which involved 136 patients who were diagnosed histologically with prostate cancer at the department of pathology between 2012 and 2014. The cases were registered at the Kampala cancer registry and followed up to 31st December 2017. Data analysis was done using STATA version 12.0. The Kaplan-Meir curves were used for analysis of the 3-year overall survival rate. Hazard ratio (HR) and Log-rank test at 95% confidence interval under Cox-regression model were used to evaluate the effect of the covariates on the 3-year overall survival rate. p<0.05 was considered statistically significant. Results. More than half of the cases, 55.9% (n=76) had Gleason score >8. Most of the patients, 67.7% (n=92) had advanced disease at diagnosis. The 3-year overall survival rate was 67.6% with median survival of 36.5 months and range of 0–65 months. Clinical stage of the patients (HR = 1.65, p=0.039), Gleason score (HR = 1.88, p=0.008), and lymphovascular invasion (HR = 0.37, p=0.002) were the independent predictors of the 3-year overall survival rate in this study. Conclusion. The 3-year overall survival of prostate cancer patients in Uganda is poor. Most of the patients with are diagnosed with advanced clinical stages (stage III and IV). The Gleason score, clinical stage and lymphovascular invasion can powerfully predict independently the overall survival of patients with prostate cancer. This implies that the Gleason score, clinical stage and lymphovascular invasion may be used to predict the overall survival of patients with prostate cancer even prior prostatectomy.

Abstract Background Being diagnosed with cancer, irrespective of type initiates a serious psychological concern. The increasing rate of detection of indolent prostate cancers is a source of worry to public health. Digital rectal examination and prostate-specific antigen tests are the commonly used prostate cancer screening tests. Understanding the diagnostic accuracies of these tests may provide clearer pictures of their characteristics and values in prostate cancer diagnosis. This review compared the sensitivities and specificities of digital rectal examination and prostate-specific antigen test in detection of clinically important prostate cancers using studies from wider population. Main body We conducted literature search in PubMed, Medline, Science Direct, Wiley Online, CINAHL, Scopus, AJOL and Google Scholar, using key words and Boolean operators. Studies comparing the sensitivity and specificity of digital rectal examination and prostate-specific antigen tests in men 40 years and above, using biopsy as reference standard were retrieved. Data were extracted and analysed using Review manager (RevMan 5.3) statistical software. The overall quality of the studies was good, and heterogeneity was observed across the studies. The result comparatively shows that prostate-specific antigen test has higher sensitivity (P < 0.00001, RR 0.74, CI 0.67–0.83) and specificity (P < 0.00001, RR 1.81, CI 1.54–2.12) in the detection of prostate cancers than digital rectal examination. Conclusion Prostate-specific antigen test has higher sensitivity and specificity in detecting prostate cancers from men of multiple ethnic origins. However, combination of prostate-specific antigen test and standardized digital rectal examination procedure, along with patients history, may improve the accuracy and minimize over-diagnoses of indolent prostate cancers.

ABSTRACT Objective: to develop a predictive model to estimate the probability of prostate cancer prior to biopsy. Methods: from September 2009 to January 2014, 445 men underwent prostate biopsy in a radiology service. We excluded from the study patients with diseases that could compromise the data analysis, who had undergone prostatic resection or used 5-alpha-reductase inhibitors. Thus, we selected 412 patients. Variables included in the model were age, prostate specific antigen (PSA), digital rectal examination, prostate volume and abnormal sonographic findings. We constructed Receiver Operating Characteristic (ROC) curves and calculated the areas under the curve, as well as the model's Positive Predictive Value (PPV) . Results: of the 412 men, 155 (37.62%) had prostate cancer (PC). The mean age was 63.8 years and the median PSA was 7.22ng/ml. In addition, 21.6% and 20.6% of patients had abnormalities on digital rectal examination and image suggestive of cancer by ultrasound, respectively. The median prostate volume and PSA density were 45.15cm3 and 0.15ng/ml/cm3, respectively. Univariate and multivariate analyses showed that only five studied risk factors are predictors of PC in the study (p<0.05). The PSA density was excluded from the model (p=0.314). The area under the ROC curve for PC prediction was 0.86. The PPV was 48.08% for 95%sensitivity and 52.37% for 90% sensitivity. Conclusion: the results indicate that clinical, laboratory and ultrasound data, besides easily obtained, can better stratify the risk of patients undergoing prostate biopsy.
