Objectives: We evaluate the role of prostate-specific antigen (PSA) density to predict Gleason score upgrade between prostate biopsy material and radical prostatectomy specimen examination in patients with low-risk prostate cancer.Methods: Between January 2007 and November 2011, 133 low-risk patients underwent a radical prostatectomy. Using the modified Gleason criteria, tumour grade of the surgical specimens was examined and compared to the biopsy results.Results: A tumour upgrade was noticed in 57 (42.9%) patients. Organ-confined disease was found in 110 (82.7%) patients, while extracapsular disease and seminal vesicles invasion was found in 19 (14.3%) and 4 (3.0%) patients, respectively. Positive surgical margins were reported in 23 (17.3%) patients. A statistical significant correlation between the preoperative PSA density value and postoperative upgrade was found (p = 0.001) and this observation had a predictive value (p = 0.002); this is in contrast to the other studied parameters which failed to reach significance, including PSA, percentage of cancer in biopsy and number of biopsy cores. Tumour upgrade was also highly associated with extracapsularcancer extension (p = 0.017) and the presence of positive surgical margins (p = 0.017).Conclusions: PSA density represents a strong predictor for Gleason score upgrade after radical prostatectomy in patients with clinical low-risk disease. Since tumour upgrade increases the potential for postoperative pathological adverse findings and prognosis, PSA density should be considered when treating and consulting patients with low-risk prostate cancer.

Introduction: Preoperative Gleason score is crucial, in combination with other preoperative parameters, in selecting the appropriate treatment for patients with clinically localized prostate cancer. The aim of the present study is to determine the clinical and pathological variables that can predict differences in Gleason score between biopsy and radical prostatectomy.Methods: We retrospectively analyzed the medical records of 302 patients who had a radical prostatectomy between January 2005 and September 2010. The association between grade changes and preoperative Gleason score, age, prostate volume, prostate-specific antigen (PSA), PSA density, number of biopsy cores, presence of prostatitis and high-grade prostatic intraepithelial neoplasia was analyzed. We also conducted a secondary analysis of the factors that influence upgrading in patients with preoperative Gleason score ≤6 (group 1) and downgrading in patients with Gleason score ≤7 (group 2).Results: No difference in Gleason score was noted in 44.3% of patients, while a downgrade was noted in 13.7% and upgrade in 42.1%. About 2/3 of patients with a Gleason score of ≤6 upgraded after radical prostatectomy. PSA density (p = 0.008) and prostate volume (p = 0.032) were significantly correlated with upgrade. No significant predictors were found for patients with Gleason score ≤7 who downgraded postoperatively.Conclusion: Smaller prostate volume and higher values of PSA density are predictors for upgrade in patients with biopsy Gleason score ≤6 and this should be considered when deferred treatment modalities are planned.

Ligoniai ir metodai Į tyrimą įtraukti 142 prostatos vėžiu sergantys ligoniai, kuriems buvo atliktos radikalios prostatektomijos. Ankstyvas biocheminis atkrytis konstatuotas, kai prostatos specifinio antigeno koncentracija, praėjus 3 mėn. po operacijos, buvo >0,2 ng/ml. Neoadjuvantinė terapija (hormonų ar spindulių) buvo pagrindinis atmetimo kriterijus. Vertinta prostatos specifinio antigeno koncentracija, vėžio diferenciacijos laipsnis iki ir po operacijos, vėžio stadija, prostatos chirurginio šalinimo išlaidos. Rezultatai Galutinei analizei panaudoti 94 ligonų duomenys. Vidutinis jų amžius buvo 66,6 metų, prostatos specifinis antigenas iki operacijos – 9,87 ng/ml, Gleason diferenciacijos laipsnis iki operacijos – 5,87, diferenciacijos laipsnis po operacijos – 6,38, teigiami rezekciniai kraštai rasti 36 (38%), ankstyvas biocheminis atkrytis – 13 (14%) pacientų. Atlikus logistinę regresijos analizę nustatyta, jog ankstyvą biocheminį atkrytį galima patikimai prognozuoti, kai Gleason pooperacinis vėžio diferenciacijos laipsnis didesnis nei 7 (p = 0,02, tikimybių santykis – 7,8) ir vėžio stadija T3b (p = 0,012, tikimybių santykis – 6,76). Išvados Remiantis ikioperaciniais objektyviais veiksniais negalima patikimai prognozuoti ankstyvo biocheminio atkryčio. Prostatos vėžio išplitimas į sėklines pūsleles (T3b stadija) ir Gleasono pooperacinis vėžio diferenciacijos laipsnis > 7 leidžia reikšmingai prognozuoti ankstyvą biocheminį atkryti, po radikalios prostatektomijos, tokiems ligoniams indikuojamas ankstyvas adjuvantinis gydymas, nelaukiant biocheminio atkryčio požymių. Reikšminiai žodžiai: prostatos vėžys, radikali prostatektomija, ankstyvas biocheminis atkrytis Can objective preoperative parameters predict early biochemical recurrence after radical prostatectomy?

Patients and methods The study embraced 142 patients that underwent radical retropubic prostatectomy. Early biochemical failure was defined as a prostate-specific antigen level 3 months after radical prostatectomy > 0.2 ng/ml. Neoadjuvant treatment (hormonal therapy or radiation) was the mane exclusion criteria. Preoperative antigen concentration, Gleason score at the biopsy, patients’ age, postoperative Gleason score, stage and surgical margins were investigated as possible predictors of early biochemical recurrence. Results Final analysis was done using data on 94 patients. The mean patients’ age was 66.6 years and mean preoperative prostate specific antigen concentration 9.87 (range 0.44–98.4) ng/ml. The mean Gleason score preoperatively was 5.87 (range 2–8) and postoperatively 6.38 (range 4–9). Positive surgical margins were in 36 (38%) and early biochemical failure was detected in 13 (14%) cases. Logistic regression analysis shows that postoperative Gleason score >7 (p = 0.02, OR-7.8) and stage pT3b (p = 0.012, OR-6.76) are powerful parameters for predicting early biochemical recurrence. Conclusions Preoperative parameters cannot predict early biochemical recurrence. Postoperative parameters such as Gleason score >7 and stage pT3b are useful in the prediction of early biochemical recurrence. In such patients early adjuvant treatment is advisable.

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.

Introduction: Prostate-specific antigen (PSA) and its kinetics have changed prostate cancer screening and diagnosis. The aim of the present study was to evaluate their value in prostate cancer prognosis by determining the predictive potential of PSA density for adverse pathologic features after radical prostatectomy, in terms of positive surgical margins (PSM), extracapsular disease (ECD), seminal vesicle invasion (SVI) and/or lymph node invasion (LNI), and to compare their predictive ability with preoperative PSA and biopsy Gleason score.Methods: We retrospectively analysed 285 patients diagnosed with prostate cancer and underwent a retropubic radical prostatectomy for clinically localized disease. Data concerning preoperative PSA, biopsy Gleason score and PSA density were collected and analyzed. PSA density was calculated by dividing preoperative PSA and the pathological volume of the prostate.Results: There was a significant difference in PSA density valuesbetween patients with PSM, ECD, SVI and LNI. Areas under thecurve for PSA density were higher than those of PSA and Gleason score for all parameters of adverse pathology. In multivariate analyses, it was shown that PSA density and Gleason score were the only statistically significant predictors for PSM and ECD, PSA density and PSA for SVI and only PSA density for LNI.Conclusion: PSA density is an accurate predictor for adverse pathology prediction in patients undergoing radical prostatectomy. Theseresults demonstrate that this parameter is useful to determine the aggressiveness of prostate cancer and can be used as an adjunct in predicting outcomes after surgery.

Background: Positive surgical margins (PSM) are an important determinant of biochemical recurrence after radical prostatectomy (RP). We use a population-based cancer registry to evaluate PSM by stage, Gleason and prostate-specific antigen (PSA).Methods: We identified men undergoing RP from the Surveillance, Epidemiology and End Results (SEER) database between 2004 and 2007. Differences between those with and without PSM were compared with chi-squared tests. The proportion of cases with PSM were stratified by PSA and Gleason sum for both pT2 and pT3a tumours. Factors associated with PSM were analyzed using chi-square and multivariate logistic regression analysis. A composite variable was used in a second multivariate analysis to display the odds ratio (OR) for a PSM for each discrete combination of PSA, Gleason score and pT stage.Results: In total, 28 461 RP patients were identified and a PSM was present in 19.5%. PSM were 42% in pT3a and 16% in pT2 cases. Higher PSAs (<4.0, 4-9.9, >10) were associated with higher proportions of PSM (12%, 20% and 28%, p < 0.001). Similarly, higher Gleason scores (≤6, 3+4, 4+3, ≥8) were associated with higher PSM (12%, 22%, 27% and 33%, p < 0.001). For pT2 tumours, the proportion of PSM ranged from 8% (Gleason ≤6, PSA <4.0) to 28% (Gleason 8-10, PSA ≥10). For pT3a tumours, the PSM was higher in each Gleason/PSA strata compared to those with pT2 tumours, reaching 63% for those with pT3a, Gleason 8-10, PSA >10 disease. On multivariate analysis, stage was the largest predictor for PSM (OR 3.05, 95% confidence interval 2.81-3.30), although Gleason score and PSA remained statistically significant.Conclusion: In this population-based study of PSM after RP, the proportion of PSM vary significantly within different PSA and Gleason strata for organ-confined and extracapsular disease. These data can be used as a reference for urologist self-assessment.

Prostate cancer (PC) remains a cause of death worldwide. Here we investigate whether a single microfocus of PC at the biopsy (graded as Gleason 6 or less, ≤5% occupancy) and the PSA <10 ng/mL can define the archetype of low-risk prostate disease. 4500 consecutive patients were enrolled. Among them, 134 patients with a single micro-focus of PC were followed up, and the parameters influencing the biochemical relapse (BR) were analysed. Out of 134 patients, 94 had clinically significant disease, specifically in 74.26% of the patients with PSA <10 ng/mL. Positive surgical margins and the extracapsular invasion were found in 29.1% and 51.4% patients, respectively. BR was observed in 29.6% of the patients. Cox regression evidenced a correlation between the BR and Gleason grade at the retropubic radical prostatectomy (RRP), capsular invasion, and the presence of positive surgical margins. Multivariate regression analysis showed a statistically significant correlation between the presence of surgical margins at the RRP and BR. Considering a single micro-focus of PC at the biopsy and PSA serum level <10 ng/mL, clinically significant disease was found in 74.26% patients and only positive surgical margins are useful for predicting the BR.
