RESUMEN
ABSTRACT: The study aimed to test if Briganti's 2012 nomogram could be associated with the risk of prostate cancer (PCa) progression in European Association of Urology (EAU) intermediate-risk patients treated with robotic surgery. From January 2013 to December 2021, 527 consecutive patients belonging to the EAU intermediate-risk class were selected. Briganti's 2012 nomogram, which predicts the risk of pelvic lymph node invasion (PLNI), was assessed as a continuous and dichotomous variable that categorized up to the median of 3.0%. Disease progression defined as biochemical recurrence and/or metastatic progression was evaluated by Cox proportional hazards (univariate and multivariate analysis). After a median follow-up of 95.0 months (95% confidence interval [CI]: 78.5-111.4), PCa progression occurred in 108 (20.5%) patients who were more likely to present with an unfavorable nomogram risk score, independently by the occurrence of unfavorable pathology including tumor upgrading and upstaging as well as PLNI. Accordingly, as Briganti's 2012 risk score increased, patients were more likely to experience disease progression (hazard ratio [HR] = 1.060; 95% CI: 1.021-1.100; P = 0.002); moreover, it also remained significant when dichotomized above a risk score of 3.0% (HR = 2.052; 95% CI: 1.298-3.243; P < 0.0001) after adjustment for clinical factors. In the studied risk population, PCa progression was independently predicted by Briganti's 2012 nomogram. Specifically, we found that patients were more likely to experience disease progression as their risk score increased. Because of the significant association between risk score and tumor behavior, the nomogram can further stratify intermediate-risk PCa patients, who represent a heterogeneous risk category for which different treatment paradigms exist.
RESUMEN
OBJECTIVES: To assess the prognostic impact and predictors of adverse tumor grade in very favorable low- and intermediate-risk prostate cancer (PCa) patients treated with robot-assisted radical prostatectomy (RARP). METHODS: Data of low- and intermediate PCa risk-class patients were retrieved from a prospectively maintained institutional database. Adverse tumor grade was defined as pathology ISUP grade group > 2. Disease progression was defined as a biochemical recurrence event and/or local recurrence and/or distant metastases. Associations were assessed by Cox's proportional hazards and logistic regression model. RESULTS: Between January 2013 and October 2020, the study evaluated a population of 289 patients, including 178 low-risk cases (61.1%) and 111 intermediate-risk subjects (38.4%); unfavorable tumor grade was detected in 82 cases (28.4%). PCa progression, which occurred in 29 patients (10%), was independently predicted by adverse tumor grade and biopsy ISUP grade group 2, with the former showing stronger associations (hazard ratio, HR = 4.478; 95% CI: 1.840-10.895; p = 0.001) than the latter (HR = 2.336; 95% CI: 1.057-5.164; p = 0.036). Older age and biopsy ISUP grade group 2 were independent clinical predictors of adverse tumor grade, associated with larger tumors that eventually presented non-organ-confined disease. CONCLUSIONS: In a very favorable PCa patient population, adverse tumor grade was an unfavorable prognostic factor for disease progression. Active surveillance in very favorable intermediate-risk patients is still a hazard, so molecular and genetic testing of biopsy specimens is needed.
RESUMEN
BACKGROUND: The aim is to evaluate factors impacting operating time (OT) during robot-assisted radical prostatectomy (RARP) with or without extended pelvic lymph node dissection (ePLND) for prostate cancer. METHODS: Overall, 1289 patients underwent RARP from January 2013 to December 2021. ePLND was performed in 825 cases. Factors potentially associated with OT variations were assessed. Three low-volume (LVS) and two high-volume surgeons (HVS) performed the procedures. A linear regression model was computed to assess associations with OT variations. RESULTS: When RARP was performed by HVS an OT decrease was observed independently by significant clinical (Body Mass Index [BMI]; prostate volume [PV]) and anatomical/perioperative features (prostate weight [PW]; intraoperative blood loss [BL]) both in clinical (change in OT: -42.979 minutes; 95% CI: -51.789; -34.169; P<0.0001) and anatomical/perioperative models (change in OT: -40.020 minutes; 95% CI: -48.494; -31.587; P<0.0001). A decreased OT was observed in clinical (change in OT: -27.656 minutes; 95% CI: -33.449; -21.864; P<0.0001) and anatomical/perioperative (change in OT: -24.935 minutes; 95% CI: -30.562; -19.308; P<0.0001) models also in case of RARP with ePLND performed by HVS, independently by BMI, PV, PSA as well as for PW, seminal vesicle invasion, positive surgical margins, and BL. CONCLUSIONS: In a tertiary academic referral center, OT decreased when RARP was performed by HVS, independently of adverse clinical and anatomical/perioperative factors. Available OT loads can be planned to optimize waiting lists, teaching tasks, operative costs, and surgeon's volume.

PURPOSE: We assessed the prognostic impact of the 2012 Briganti nomogram on prostate cancer (PCa) progression in intermediate-risk (IR) patients presenting with PSA <10ng/mL, ISUP grade group 3, and clinical stage up to cT2b treated with robot assisted radical prostatectomy eventually associated with extended pelvic lymph node dissection. MATERIALS AND METHODS: From January 2013 to December 2021, data of surgically treated IR PCa patients were retrospectively evaluated. Only patients presenting with the above-mentioned features were considered. The 2012 Briganti nomogram was assessed either as a continuous and a categorical variable (up to the median, which was detected as 6%, vs. above the median). The association with PCa progression, defined as biochemical recurrence, and/or metastatic progression, was evaluated by Cox proportional hazard regression models. RESULTS: Overall, 147 patients were included. Compared to subjects with a nomogram score up to 6%, those presenting with a score above 6% were more likely to be younger, had larger/palpable tumors, presented with higher PSA, underwent tumor upgrading, harbored non-organ confined disease, and had positive surgical margins at final pathology. PCa progression, which occurred in 32 (21.7%) cases, was independently predicted by the 2012 Briganti nomogram both considered as a continuous (Hazard Ratio [HR]:1.04, 95% Confidence Interval [CI]:1.01-1.08;p=0.021), and a categorical variable (HR:2.32; 95%CI:1.11-4.87;p=0.026), even after adjustment for tumor upgrading. CONCLUSIONS: In IR PCa patients with PSA <10ng/mL, ISUP grade group 3, and clinical stage up to cT2b, the 2012 Briganti nomogram independently predicts PCa progression. In this challenging subset of patients, this tool can identify prognostic subgroups, independently by upgrading issues.

BACKGROUND: To investigate the potential prognostic impact of Briganti's 2012 nomogram in EAU intermediate-risk patients presenting with an unfavorable tumor grade and treated with robot-assisted radical prostatectomy, eventually associated with extended pelvic lymph node dissection. MATERIALS AND METHODS: From January 2013 to December 2021, the study included 179 EAU intermediate-risk patients presenting with an unfavorable tumor grade (ISUP 3), eventually associated with a PSA of 10-20 ng/ml and/or cT-2b. Briganti's 2012 nomogram was assessed as both a continuous and dichotomous variable, categorized according to the median (risk score ⩾7% vs <7%). Disease progression, defined as biochemical recurrence and/or metastatic progression, was evaluated using Cox proportional hazards in both univariate and multivariate analyses. RESULTS: Disease progression occurred in 43 (24%) patients after a median (95% CI) follow-up of 78 (65.7-88.4) months. The nomogram risk score predicted disease progression, evaluated both as a continuous variable (hazard ratio, HR = 1.064; 95% CI: 1.035-1.093; p < 0.0001) and as a categorical variable (HR = 3.399; 95% CI: 1.740-6.638; p < 0.0001). This association was confirmed in multivariate analysis, where hazard ratios remained consistent even after adjusting for clinical and pathological factors. CONCLUSIONS: In EAU intermediate-risk PCa cases presenting with an unfavorable tumor grade and treated surgically, Briganti's 2012 nomogram was associated with disease progression after surgery. Consequently, as the nomogram risk score increased, patients were more likely to experience PCa progression, facilitating the stratification of the patient population into distinct prognostic subgroups.

PURPOSE: We sought to investigate predictors of unfavorable tumor upgrading in very favorable intermediate-risk (IR) prostate cancer (PCa) patients treated with robot-assisted radical prostatectomy, in addition to evaluate how it may affect the risk of disease progression. METHODS: A very favorable subset of IR PCa patients presenting with prostate-specific antigen (PSA) < 10 ng/mL, percentage of biopsy positive cores (BPC) < 50%, and either International Society of Urological Pathology (ISUP) grade group 1 and clinical stage T2b or ISUP grade group 2 and clinical stage T1c-2b was identified. Unfavorable pathology at radical prostatectomy was defined as the presence of ISUP grade group > 2 (unfavorable tumor upgrading), extracapsular extension (ECE), and seminal vesicle invasion (SVI). Disease progression was defined as the event of biochemical recurrence and/or local recurrence and/or distant metastases. Associations were evaluated by Cox regression and logistic regression analyses. RESULTS: Overall, 210 patients were identified between January 2013 and October 2020. Unfavorable tumor upgrading was detected in 71 (33.8%) cases, and adverse tumor stage, including ECE or SVI in 18 (8.6%) and 11 (5.2%) patients, respectively. Median (interquartile range) follow-up was 38.5 (16-61) months. PCa progression occurred in 24 (11.4%) patients. Very favorable IR PCa patients with unfavorable tumor upgrading at final pathology showed a persistent risk of disease progression, which hold significance after adjustment for all factors (Hazard Ratio [HR]: 5.95, 95% Confidence Interval [CI]: 1.97-17.92, p = 0.002) of which PSA was an independent predictor (HR: 1.52, 95% CI 1.12-2.08, p = 0.008). Moreover, these subjects were more likely to belong to the biopsy ISUP grade group 2. CONCLUSIONS: Very favorable IR PCa patients hiding unfavorable tumor upgrading were more likely to experience disease progression. Unfavorable tumor upgrading involved about one-third of cases and was less likely to occur in patients presenting with biopsy ISUP grade group 1. Tumor misclassification is an issue to discuss, when counseling this subset of patients for active surveillance because of the risk of delayed active treatment.

To evaluate the prognostic potential of the 2012 Briganti nomogram for pelvic lymph node invasion on disease progression after surgery in intermediate-risk (IR) prostate cancer (PCa) patients with favorable tumor grade (International Society of Urological Pathology grade group 1 or 2), eventually associated with adverse clinical features as PSA between 10 and 20 ng/mL and/or clinical stage T2b. All IR PCa patients treated with robot-assisted radical prostatectomy and eventually extended pelvic lymph node dissection at the Department of Urology of the Integrated University Hospital of Verona between 2013 and 2021, with the abovementioned features, and available follow-up were considered. The 2012 Briganti nomogram score was assessed both as a continuous and dichotomous variable, where a mean risk score of 4% was used a threshold. The independent predictor status of the nomogram score on disease progression defined as the occurrence of biochemical recurrence and/or metastatic progression was evaluated using the Cox regression analysis. Overall, 348 patients were enrolled in the study. Median (interquartile range) follow-up was 98 (83.5-112.4) months. At multivariable Cox regression analysis, PCa progression, which occurred in 65 (18.7%) cases, was independently predicted only by the 2012 Briganti nomogram score evaluated as a continuous variable, among all considered clinical features (HR 1.16; 95%CI 1.08-1.24; p < 0.001). In addition, patients presenting with a nomogram score ≥ 4% were more likely to experience disease progression even after adjustment for clinical (HR 2.22, 95%CI 1.02-4.79; p = 0.043) and pathological (HR 1.80; 95%CI 1.06-3.05; p = 0.031) factors. In the examined patient population, the 2012 Briganti nomogram predicted PCa progression after surgery. Accordingly, as the risk score increased, patients were more likely to progress, independently by the occurrence of adverse pathology in the surgical specimen. The 2012 Briganti nomogram score categorized according to the mean value allowed to identify prognostic subgroups.

Background: Treatment outcomes in intermediate-risk prostate cancer (PCa) may be impaired by adverse pathology misclassification including tumor upgrading and upstaging. Clinical predictors of disease progression need to be improved in this category of patients. Objectives: To identify PCa prognostic factors to define prognostic groups in intermediate-risk patients treated with robot-assisted radical prostatectomy (RARP). Design: Data from 1143 patients undergoing RARP from January 2013 to October 2020 were collected: 901 subjects had available follow-up, of whom 479 were at intermediate risk. Methods: PCa progression was defined as biochemical recurrence and/or local recurrence and/or distant metastases. Study endpoints were evaluated by statistical methods including Cox's proportional hazards, Kaplan-Meyer survival curves, and binomial and multinomial logistic regression models. Results: After a median (interquartile range) of 35 months (15-57 months), 84 patients (17.5%) had disease progression, which was independently predicted by the percentage of biopsy-positive cores ⩾ 50% and the International Society of Urological Pathology (ISUP) grade group 3 for clinical factors and by ISUP > 2, positive surgical margins and pelvic lymph node invasion for pathological features. Patients were classified into clinical and pathological groups as favorable, unfavorable (one prognostic factor), and adverse (more than one prognostic factor). The risk of PCa progression increased with worsening prognosis through groups. A significant positive association was found between the two groups; consequently, as clinical prognosis worsened, the risk of detecting unfavorable and adverse pathological prognostic clusters increased in both unadjusted and adjusted models. Conclusion: The study identified factors predicting disease progression that allowed the computation of highly correlated prognostic groups. As the prognosis worsened, the risk of PCa progression increased. Intermediate-risk PCa needs more prognostic stratification for appropriate management.
A study on 479 patients looked at how prognostic group classification affects progression in patients with intermediate-risk prostate cancer treated with robot-assisted radical prostatectomy Prostate cancer is a serious health concern in men, and those with intermediate-risk prostate cancer may experience disease progression. Urologists use various methods to predict the risk of progression in these patients. However, sometimes the predictions are not accurate. Therefore, researchers conducted a study to identify factors that could help predict disease progression in patients with intermediate-risk prostate cancer who underwent robot-assisted surgery. This study on 479 patients found that a percentage of biopsy-positive cores ⩾ 50% and the International Society of Urological Pathology (ISUP) grade group 3 were predictive factors of disease progression. Additionally, factors like ISUP > 2, positive surgical margins, and pelvic lymph node invasion also predicted disease progression. Patients were classified into three groups based on their clinical and pathological features: favorable, unfavorable (one negative prognostic factor), and adverse (more than one negative prognostic factor). The risk of prostate cancer progression increased as the prognosis worsened through these groups. The study concluded that a more accurate stratification of intermediate-risk prostate cancer patients is needed to manage the disease effectively.
RESUMEN
OBJECTIVE: To evaluate the influence of endogenous testosterone density (ETD) and tumor load density (TLD) in the surgical specimen of prostate cancer (PCa) patients. METHODS: ETD was assessed as the ratio of endogenous testosterone (ET) to prostate volume (PV). TLD was calculated as the ratio of tumor load (TL) to prostate weight. Preoperative prostate-specific antigen relative densities (PSAD) and percentage of biopsy-positive cores (BPCD) were also assessed. The association of high TLD (above the first quartile) with clinical and pathological factors was assessed by the logistic regression model (univariate and multivariate analysis). RESULTS: Between November 2014 and December 2019, ET was measured in 805 cases treated with radical prostatectomy (RP). Median (IQR) of ET and ETD was 412 (321.4-519 ng/dL) and 9.8 (6.8-14.4 ng/(dLxmL)) as well as for TL and TLD was 20 (10-30%) and 0.33 (0.17-0.58%/gr), respectively. As a result, high TLD was detected in 75% of cases. A positive independent association was found between high TLD and ETD. Accordingly, as ETD levels increased, the risk of detecting high TLD in the surgical specimen increased, regardless of PSAD and BPCD. CONCLUSIONS: At diagnosis of PCa, a positive independent association was found between ETD and risk of high TLD. Subjects with increasing ETD levels were more likely to have high TLD, associated with unfavorable pathology features. The positive association between ETD and TLD in the prostate microenvironment might adversely influence PCa's natural history.

CONTEXT: Despite negative preoperative conventional imaging, up to 10% of patients with prostate cancer (PCa) harbor lymph-node involvement (LNI) at radical prostatectomy (RP). The advent of more accurate imaging modalities such as PET/CT improved the detection of LNI. However, their clinical impact and prognostic value are still unclear. We aimed to investigate the prognostic value of preoperative PET/CT in patients node positive (pN+) at RP. EVIDENCE SYNTHESIS: We retrospectively identified cN0M0 patients at conventional imaging (CT and/or MRI, and bone scan) who had pN+ PCa at RP at 17 referral centers. Patients with cN+ at PSMA/Choline PET/CT but cN0M0 at conventional imaging were also included. Systemic progression/recurrence was the primary outcome; Cox proportional hazards models were used for multivariate analysis. EVIDENCE ACQUISITION: We included 1163 pN+ men out of whom 95 and 100 had preoperative PSMA and/or Choline PET/CT, respectively. ISUP grade ≥4 was detected in 66.6%. Overall, 42% of patients had postoperative PSA persistence (≥0.1 ng/mL). Postoperative management included initial observation (34%), ADT (22.7%) and adjuvant RT+/-ADT (42.8%). Median follow-up was 42 months. Patients with cN+ on PSMA PET/CT had an increased risk of systemic progression (52.9% vs. 13.6% cN0 PSMA PET/CT vs. 21.5% cN0 at conventional imaging; P < .01). This held true at multivariable analysis: (HR 6.184, 95% CI: 3.386-11-295; P < .001) whilst no significant results were highlighted for Choline PET/CT. No significant associations for both PET types were found for local progression, BCR, and overall mortality (all P > .05). Observation as an initial management strategy instead of adjuvant treatments was related with an increased risk of metastases (HR 1.808; 95% CI: 1.069-3.058; P < .05). CONCLUSIONS: PSMA PET/CT cN+ patients with negative conventional imaging have an increased risk of systemic progression after RP compared to their counterparts with cN0M0 disease both at conventional and/or molecular imaging.

BACKGROUND: Routine processing of prostate biopsies requires conventional steps that usually take a few days. The aim of this study was to validate the use of fluorescence laser confocal microscopy (FCM) for real-time diagnostics. METHODS: We prospectively tested images from prostate needle biopsies (75 images were evaluated by FCM and conventional slides). Two pathologists reviewed the images and assessed agreements between FCM versus conventional slides and between pathologists (κ-values). Interpretation was performed on digital images from the VivaScope 2500 confocal microscope (MAVIG GmbH, Munich, Germany; Caliber I.D., Rochester, NY, USA) placed in the urological operating room. Cancerous versus benign tissue was the primary focus, then the application of the grading system. RESULTS: Cancer was diagnosed in 24 conventional slides (on 75 images) in which agreement among pathologists was high for both conventional (κ=0.96) and FMC (κ=0.84). 1/24 (4%) was ISUP/WHO grade group I, 12/24 (50%) II, 8/24 (33%) III, 2/24 (8%) IV and 1/24 (4%) grade V. Near perfect agreement was obtained for grades I, IV and V (κ=0.85). Grade III values achieved a moderate agreement (κ=0.55). The mean time for laser scanning was 9 minutes. For the remaining non-tumor images, agreement was nearly perfect (κ=0.81). CONCLUSIONS: We validated the use of FCM for real-time cancer detection in prostate biopsies.

OBJECTIVE: This study aimed to evaluate the impact of palpable prostate tumors on digital rectal exam (DRE) on the disease progression of prostate cancer (PCa) treated with RARP surgery in a tertiary referral center. MATERIALS AND METHODS: Overall, 901 patients were evaluated in a period ranging from January 2013 to October 2020. In the surgical specimen, unfavorable pathology included ISUP grade group ≥3, seminal vesicle invasion (SVI), and pelvic lymph node invasion (PLNI). Disease progression was defined as the occurrence of biochemical recurrence and/or local recurrence and/or distant metastases; its association with the primary endpoint was evaluated by Cox's proportional model. RESULTS: Palpable prostate tumors were detected in 359 (39.8%) patients. The overall median (IQR) follow-up was 40 months (17-59). PCa progressed in 159 cases (17.6%). Nodularity or induration of the prostate at DRE was significantly associated with features of unfavorable pathology, increased risk of PCa progression (hazard ratio, HR = 1.902; 95% CI: 1.389-2.605; p < 0.0001) and, on multivariable analysis, was an independent prognostic factor for disease progression after adjusting for clinical and pathological variables. CONCLUSIONS: Prostate tumors presenting with an abnormal DRE finding have an independent adverse outcome for disease progression after PCa surgery. They provide also independent prognostic information, as they may be more aggressive than impalpable PCa.

OBJECTIVES: This study aimed to assess more clinical and pathological factors associated with prostate cancer (PCa) progression in high-risk PCa patients treated primarily with robot-assisted radical prostatectomy (RARP) and extended pelvic lymph node dissection (ePLND) in a tertiary referral center. MATERIALS AND METHODS: In a period ranging from January 2013 to October 2020, RARP and ePLND were performed on 180 high-risk patients at Azienda Ospedaliera Universitaria Integrata of Verona (Italy). PCa progression was defined as biochemical recurrence/persistence and/or local recurrence and/or distant metastases. Statistical methods evaluated study endpoints, including Cox's proportional hazards, Kaplan-Meyer survival curves, and binomial logistic regression models. RESULTS: The median age of included patients was 66.5 [62-71] years. Disease progression occurred in 55 patients (30.6%), who were more likely to have advanced age, palpable tumors, and unfavorable pathologic features, including high tumor grade, stage, and pelvic lymph node invasion (PLNI). On multivariate analysis, PCa progression was predicted by advanced age (≥ 70 years) (HR = 2.183; 95% CI = 1.089-4377, p = 0.028), palpable tumors (HR = 3.113; 95% CI = 1.499-6.465), p = 0.002), and PLNI (HR = 2.945; 95% CI = 1.441-6.018, p = 0.003), which were associated with clinical standard factors defining high-risk PCa. Age had a negative prognostic impact on elderly patients, who were less likely to have palpable tumors but more likely to have high-grade tumors. CONCLUSIONS: High-risk PCa progression was independently predicted by advanced age, palpable tumors, and PLNI, which is associated with standard clinical prognostic factors. Consequently, with increasing age, the prognosis is worse in elderly patients, who represent an unfavorable age group that needs extensive counseling for appropriate and personalized management decisions.

PURPOSE: To test the role of endogenous total testosterone (ETT) as a predictor of prostate cancer (PCa) progression in patients treated with robot assisted radical prostatectomy for clinically localized disease. METHODS: Between November 2014 and December 2019, 580 consecutive patients were evaluated. Preoperative ETT levels were classified as ≤ 350 ng/dL vs. > 350 ng/dL. The associations between ETT levels and the risk of PCa progression, defined as any event of biochemical recurrence and/or local recurrence and/or distant metastases, or other clinical and pathological factors were evaluated by regression analyses. RESULTS: Preoperative ETT levels resulted ≤ 350 ng/dL in 173 (29.8%) patients. Disease progression occurred in 101 (17.1%) cases. Progressing patients were more likely to present with PSA levels > 10 ng/mL, as well as with unfavorable tumor grade (ISUP 4-5) and stage (pT3b) at final pathology, but less likely to have ETT levels ≤ 350 ng/mL. On clinical multivariable Cox regression models, ETT ≤ 350 ng/mL exhibited a statistically significant protective effect on tumor progression (hazard ratio: 0.57, p = 0.013). Subjects presenting with ETT levels ≤ 350 ng/mL were less likely to harbor ISUP 4-5 tumor grade either at biopsy (odds ratio [OR]: 0.46, p = 0.028) or final pathology (OR: 0.45, p = 0.032). CONCLUSIONS: At PCa diagnosis, ETT, which associates with ISUP tumor grade, is an independent predictor of disease progression. Accordingly, as ETT decreases to levels ≤ 350 ng/dL, the risk of unfavorable tumor grade decreases, and a more favorable prognosis is expected. Preoperative ETT levels may allow further patient stratification along prognostic risk groups.

Background: The impact of senior age on prostate cancer (PCa) oncological outcomes following radical prostatectomy (RP) is controversial, and further clinical factors could help stratifying risk categories in these patients. Objective: We tested the association between endogenous testosterone (ET) and risk of PCa progression in elderly patients treated with RP. Design: Data from PCa patients treated with RP at a single tertiary referral center, between November 2014 and December 2019 with available follow-up, were retrospectively evaluated. Methods: Preoperative ET (classified as normal if >350 ng/dl) was measured for each patient. Patients were divided according to a cut-off age of 70 years. Unfavorable pathology consisted of International Society of Urologic Pathology (ISUP) grade group >2, seminal vesicle, and pelvic lymph node invasion. Cox regression models tested the association between clinical/pathological tumor features and risk of PCa progression in each age subgroup. Results: Of 651 included patients, 190 (29.2%) were elderly. Abnormal ET levels were detected in 195 (30.0%) cases. Compared with their younger counterparts, elderly patients were more likely to have pathological ISUP grade group >2 (49.0% versus 63.2%). Disease progression occurred in 108 (16.6%) cases with no statistically significant difference between age subgroups. Among the elderly, clinically progressing patients were more likely to have normal ET levels (77.4% versus 67.9%) and unfavorable tumor grades (90.3% versus 57.9%) than patients who did not progress. In multivariable Cox regression models, normal ET [hazard ratio (HR) = 3.29; 95% confidence interval (CI) = 1.27-8.55; p = 0.014] and pathological ISUP grade group >2 (HR = 5.62; 95% CI = 1.60-19.79; p = 0.007) were independent predictors of PCa progression. On clinical multivariable models, elderly patients were more likely to progress for normal ET levels (HR = 3.42; 95% CI = 1.34-8.70; p = 0.010), independently by belonging to high-risk category. Elderly patients with normal ET progressed more rapidly than those with abnormal ET. Conclusion: In elderly patients, normal preoperative ET independently predicted PCa progression. Elderly patients with normal ET progressed more rapidly than controls, suggesting that longer exposure time to high-grade tumors could adversely impact sequential cancer mutations, where normal ET is not anymore protective on disease progression.
RESUMEN
We tested the association between endogenous testosterone density (ETD; the ratio between endogenous testosterone [ET] and prostate volume) and prostate cancer (PCa) aggressiveness in very favorable low- and intermediate-risk PCa patients who underwent radical prostatectomy (RP). Only patients with prostate-specific antigen (PSA) within 10 ng ml -1 , clinical stage T1c, and International Society of Urological Pathology (ISUP) grade group 1 or 2 were included. Preoperative ET levels up to 350 ng dl -1 were classified as abnormal. Tumor quantitation density factors were evaluated as the ratio between percentage of biopsy-positive cores and prostate volume (biopsy-positive cores density, BPCD) and the ratio between percentage of cancer invasion at final pathology and prostate weight (tumor load density, TLD). Disease upgrading was coded as ISUP grade group >2, and progression as recurrence (biochemical and/or local and/or distant). Risk associations were evaluated by multivariable Cox and logistic regression models. Of 320 patients, 151 (47.2%) had intermediate-risk PCa. ET (median: 402.3 ng dl -1 ) resulted abnormal in 111 (34.7%) cases (median ETD: 9.8 ng dl -1 ml -1 ). Upgrading and progression occurred in 109 (34.1%) and 32 (10.6%) cases, respectively. Progression was predicted by ISUP grade group 2 (hazard ratio [HR]: 2.290; P = 0.029) and upgrading (HR: 3.098; P = 0.003), which was associated with ISUP grade group 2 (odds ratio [OR]: 1.785; P = 0.017) and TLD above the median (OR: 2.261; P = 0.001). After adjustment for PSA density and body mass index (BMI), ETD above the median was positively associated with BPCD (OR: 3.404; P < 0.001) and TLD (OR: 5.238; P < 0.001). Notably, subjects with abnormal ET were more likely to have higher BPCD (OR: 5.566; P = 0.002), as well as TLD (OR: 14.998; P = 0.016). Independently by routinely evaluated factors, as ETD increased, BPCD and TLD increased, but increments were higher for abnormal ET levels. In very favorable cohorts, ETD may further stratify the risk of aggressive PCa.
RESUMEN
BACKGROUND: Since before the COVID-19 pandemic, hospital-acquired infections (HAIs) represented a global healthcare crisis. Few studies suggested that COVID-19-related basic hygiene measures (BHM) could lower HAIs rates, reaching inconclusive results. The aim of this study was to investigate the hypothetical benefit on HAIs rate of COVID-19-enhanced BHM systematic introduction after major elective urological surgery. METHODS: Since the pandemic began, our hospital has implemented BHM to limit the spread of COVID-19. We compared patients operated in the pre-COVID-19 era (no-BHM period) with those operated after the pandemic started (BHM period). Outcomes were the incidence of HAIs and postoperative complications, and the length of hospital stay (LOS). Two balanced groups were generated by propensity score 1:1 matching. RESULTS: Of 1053 major urological interventions, 604 were performed in the no-BHM period, and 449 in the BHM period. After matched analysis, the comparison groups consisted of 310 patients each. Of 107 recorded HAIs, 43 occurred during the BHM period (13.9%), and 64 during the no-BHM period (20.7%), with a statistically significant difference in multivariable analysis (OR 0.5 [95% CI 0.3-0.8], P=0.004). Postoperative complications rate was significantly lower in the BHM period than in the no-BHM period (29.0% versus 36.5%, OR 0.6 [95% CI 0.4-0.9], P=0.01). The LOS differed significantly between BHM and no-BHM periods: a median of 5 (5-8) days versus 6 (5-8), respectively (P<0.001). CONCLUSIONS: The risk of infections, postoperative complications, and prolonged LOS after major urological surgery was significantly reduced with the systematic introduction of COVID-19-related BHM, their application could, therefore, be prolonged with lasting benefits.

OBJECTIVE: To investigate endogenous testosterone density (ETD) predicting disease progression from clinically localized impalpable prostate cancer (PCa) presenting with prostate-specific antigen (PSA) levels elevated up to 10 ng/mL and treated with radical prostatectomy. MATERIALS AND METHODS: In a period ranging from November 2014 to December 2019, 805 consecutive PCa patients who were not under androgen blockade had endogenous testosterone (ET, ng/dL) measured before surgery. ETD was evaluated as the ratio of ET on prostate volume (PV). Unfavorable disease was defined as including ISUP ≥ 3 and/or seminal vesicle invasion in the surgical specimen. The risk of disease progression was evaluated by statistical methods. RESULTS: Overall, the study selected 433 patients, of whom 353 (81.5%) had available follow-up. Unfavorable disease occurred in 46.7% of cases and was predicted by tumor quantitation features that were positively associated with ETD. Disease progression, which occurred for 46 (13%) cases, was independently predicted only by ETD (hazard ratio, HR = 1.037; 95% CI 1.004-1.072; p = 0.030) after adjusting for unfavorable disease. According to a multivariate model, ETD above the third quartile was confirmed to be an independent predictor for PCa progression (HR = 2.479; 95% CI 1.355-4.534; p = 0.003) after adjusting for unfavorable disease. The same ETD measurements, ET mean levels were significantly lower in progressing cancers. CONCLUSIONS: In this particular subset of patients, increased ETD with low ET levels, indicating androgen independence, resulted in a more aggressive disease with poorer prognosis.

To test the hypothesis of an association between the American Society of Anesthesiologists (ASA) physical status classification system and the risk of 90-days postoperative complications after robot-assisted radical prostatectomy (RARP), graded using the Clavien-Dindo classification system (CDS). In a period ranging from January 2013 to October 2020, 1143 patients were evaluated. ASA classification was computed by trained anesthesiologists. Postoperative complications at 90 days after RARP were grouped as greater than one (CDS between 2 and 4a) versus up to one (CDS between 0 and 1). The risk association was computed using logistic regression models. According to ASA physical status classification system, patients were distributed as follows: 102 (8.9%) ASA 1, 934 (81.7%) ASA 2, and 107 (9.4%) ASA 3. Overall, 90-days postoperative complications occurred in 277 (24.2%) cases, of which 137 (12%) were graded as CDS 1 vs. 105 (9.2%) CDS 2 vs. 17 (1.5%) CDS 3a vs. 15 (1.3%) CDS 3b vs. 3 (0.3%) CDS 4a. ASA 2 and 3 patient categories were more likely to have 90-days postoperative complications CDS > 1 (12.5% and 16.8%, respectively) compared to ASA 1 patients (4.9%). The risk association was stronger for ASA 3 (odds ratio, [OR]: 4.085; 95%CI: 1.457-11.455; p = 0.007) than for ASA 2 (OR: 2.907; 95%CI: 1.106-7.285; p = 0.023) patient categories. After adjustment for clinical, pathological, and perioperative covariates, including pelvic lymph node dissection (performed vs. not performed), either ASA 2 or 3 categories remained independent predictors of 90-days postoperative complications CDS > 1. The risk of 90-days postoperative complications CDS > 1 after RARP increased as the ASA physical status deteriorated independently by performing or not an extended pelvic lymph node dissection. In the ASA 3 patients category, RARP should be performed at tertiary referral centers to safely manage the risk of postoperative complications.

Objective: to evaluate predictors and the prognostic impact of favorable vs. unfavorable tumor upgrading among low-risk prostate cancer (LR PCa) patients treated with robot-assisted radical prostatectomy (RARP). Methods: From January 2013 to October 2020, LR PCa patients treated with RARP at our institution were identified. Unfavorable tumor upgrading was defined as the presence of an International Society of Urological Pathology (ISUP) grade group at final pathology > 2. Disease relapse was coded as biochemical recurrence and/or local recurrence and/or presence of distant metastases. Regression analyses tested the association between clinical and pathological features and the risk of unfavorable tumor upgrading and disease relapse. Results: Of the 237 total LR PCa patients, 60 (25.3%) harbored unfavorable tumor upgrading. Disease relapse occurred in 20 (8.4%) patients. Unfavorable upgrading represented an independent predictor of disease relapse, even after adjustment for other clinical and pathological variables. Conversely, favorable tumor upgrading did not show any statistically significant association with PCa relapse. Unfavorable tumor upgrading was associated with tumors being larger (OR: 1.03; p = 0.031), tumors extending beyond the gland (OR: 8.54, p < 0.001), age (OR: 1.07, p = 0.009), and PSA density (PSAD) ≥ 0.15 ng/mL/cc (OR: 1.07, p = 0.009). Conclusions: LR PCa patients with unfavorable upgrading at final pathology were more likely to be older, to have PSAD ≥ 0.15 ng/mL/cc, and to experience disease relapse. Unfavorable tumor upgrading is an issue to consider when counseling these patients to avoid delayed treatments, which may impair cancer-specific survival.
