Development of a microultrasound-based nomogram to predict extra-prostatic extension in patients with prostate cancer undergoing robot-assisted radical prostatectomy. Urol Oncol 2024; 42:159.e9-159.e16. [PMID: 38423852 DOI: 10.1016/j.urolonc.2024.01.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 01/12/2024] [Accepted: 01/26/2024] [Indexed: 03/02/2024]
Abstract
OBJECTIVES To develop a microultrasound-based nomogram including clinicopathological parameters and microultrasound findings to predict the presence of extra-prostatic extension and guide the grade of nerve-sparing. MATERIAL AND METHODS All patients underwent microultrasound the day before robot-assisted radical prostatectomy. Variables significantly associated with extra-prostatic extension at univariable analysis were used to build the multivariable logistic model, and the regression coefficients were used to develop the nomogram. The model was subjected to 1000 bootstrap resamples for internal validation. The performance of the microultrasound-based model was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve, calibration plot, and decision curve analysis (DCA). RESULTS Overall, 122/295 (41.4%) patients had a diagnosis of extra-prostatic extension on definitive pathology. Microultrasound correctly identify extra-prostatic extension in 84/122 (68.9%) cases showing a sensitivity and a specificity of 68.9% and 84.4%, with an AUC of 76.6%. After 1000 bootstrap resamples, the predictive accuracy of the microultrasound-based model was 85.9%. The calibration plot showed a satisfactory concordance between predicted probabilities and observed frequencies of extra-prostatic extension. The DCA showed a higher clinical net-benefit compared to the model including only clinical parameters. Considering a 4% cut-off, nerve-sparing was recommended in 173 (58.6%) patients and extra-prostatic extension was detected in 32 (18.5%) of them. CONCLUSION We developed a microultrasound-based nomogram for the prediction of extra-prostatic extension that could aid in the decision whether to preserve or not neurovascular bundles. External validation and a direct comparison with mpMRI-based nomogram is crucial to corroborate our results.

Fine-scale foraging ecology and habitat use of sympatric green and hawksbill turtles in the Western Indian ocean. MARINE ENVIRONMENTAL RESEARCH 2024; 198:106529. [PMID: 38688109 DOI: 10.1016/j.marenvres.2024.106529] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 04/01/2024] [Accepted: 04/26/2024] [Indexed: 05/02/2024]
Abstract
Using stable isotope analysis of carbon and nitrogen of turtle tissues and putative prey items, we investigated the diet of immature green turtles and hawksbill turtles foraging in the lagoon of Aldabra Atoll, a relatively undisturbed atoll in the southern Seychelles. Aldabra offers a unique environment for understanding sea turtle ecology. Green turtles mostly consumed seagrass and brown algae while hawksbill turtles mainly consumed mangroves and invertebrates. Green turtles showed a dietary shift with size (a proxy for age). There was minimal niche overlap between species and evidence of small-scale foraging site fidelity with turtle tissue reflecting site-specific prey. This highlights the ecological importance of seagrass and mangrove habitats and suggests that turtles play a role in controlling algal biomass at Aldabra. This study is the first to closely examine the foraging ecology of these sympatric turtle species in the Western Indian Ocean, a globally important region for both species.

Ureteral stricture rate after endoscopic treatments for urolithiasis and related risk factors: systematic review and meta-analysis. World J Urol 2024; 42:234. [PMID: 38613692 DOI: 10.1007/s00345-024-04933-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 03/15/2024] [Indexed: 04/15/2024] Open
Abstract
PURPOSE We aimed to accurately determine ureteral stricture (US) rates following urolithiasis treatments and their related risk factors. METHODS We conducted a systematic review and meta-analysis following the PRISMA guidelines using databases from inception to November 2023. Studies were deemed eligible for analysis if they included ≥ 18 years old patients with urinary lithiasis (Patients) who were subjected to endoscopic treatment (Intervention) with ureteroscopy (URS), percutaneous nephrolithotomy (PCNL), or shock wave lithotripsy (SWL) (Comparator) to assess the incidence of US (Outcome) in prospective and retrospective studies (Study design). RESULTS A total of 43 studies were included. The pooled US rate was 1.3% post-SWL and 2.1% post-PCNL. The pooled rate of US post-URS was 1.9% but raised to 2.7% considering the last five years' studies and 4.9% if the stone was impacted. Moreover, the pooled US rate differed if follow-ups were under or over six months. Patients with proximal ureteral stone, preoperative hydronephrosis, intraoperative ureteral perforation, and impacted stones showed higher US risk post-endoscopic intervention with odds ratio of 1.6 (P = 0.05), 2.6 (P = 0.009), 7.1 (P < 0.001), and 7.47 (P = 0.003), respectively. CONCLUSIONS The overall US rate ranges from 0.3 to 4.9%, with an increasing trend in the last few years. It is influenced by type of treatment, stone location and impaction, preoperative hydronephrosis and intraoperative perforation. Future standardized reporting and prospective and more extended follow-up studies might contribute to a better understanding of US risks related to calculi treatment.

Prognostic role of platelet-to-lymphocyte ratio and neutrophil-to-lymphocyte ratio in patients with non-metastatic and metastatic prostate cancer: A meta-analysis and systematic review. Asian J Urol 2024; 11:191-207. [PMID: 38680577 PMCID: PMC11053338 DOI: 10.1016/j.ajur.2023.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2022] [Accepted: 10/13/2022] [Indexed: 02/08/2023] Open
Abstract
Objective To analyze data available in the literature regarding a possible prognostic value of the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) in prostate cancer (PCa) patients stratified in non-metastatic and metastatic diseases. Methods A literature search process was performed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. In our meta-analysis, the pooled event rate estimated and the pooled hazard ratio were calculated using a random effect model. Results Forty-two articles were selected for our analysis. The pooled risk difference for non-organ confined PCa between high and low NLR cases was 0.06 (95% confidence interval [CI]: -0.03-0.15) and between high and low PLR cases increased to 0.30 (95% CI: 0.16-0.43). In non-metastatic PCa cases, the pooled hazard ratio for overall mortality between high and low NLR was 1.33 (95% CI: 0.78-1.88) and between high and low PLR was 1.47 (95% CI: 0.91-2.03), whereas in metastatic PCa cases, between high and low NLR was 1.79 (95% CI: 1.44-2.13) and between high and low PLR was 1.05 (95% CI: 0.87-1.24). Conclusion The prognostic values of NLR and PLR in terms of PCa characteristics and responses after treatment show a high level of heterogeneity of results among studies. These two ratios can represent the inflammatory and immunity status of the patient related to several conditions. A higher predictive value is related to a high NLR in terms of risk for overall mortality in metastatic PCa cases under systemic treatments.

A Comparative Evaluation of Multiparametric Magnetic Resonance Imaging and Micro-Ultrasound for the Detection of Clinically Significant Prostate Cancer in Patients with Prior Negative Biopsies. Diagnostics (Basel) 2024; 14:525. [PMID: 38472997 DOI: 10.3390/diagnostics14050525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 02/25/2024] [Accepted: 02/27/2024] [Indexed: 03/14/2024] Open
Abstract
BACKGROUND The diagnostic process for prostate cancer after a negative biopsy is challenging. This study compares the diagnostic accuracy of micro-ultrasound (mUS) with multiparametric magnetic resonance imaging (mpMRI) for such cases. METHODS A retrospective cohort study was performed, targeting men with previous negative biopsies and using mUS and mpMRI to detect prostate cancer and clinically significant prostate cancer (csPCa). RESULTS In our cohort of 1397 men, 304 had a history of negative biopsies. mUS was more sensitive than mpMRI, with better predictive value for negative results. Importantly, mUS was significantly associated with csPCa detection (adjusted odds ratio [aOR]: 6.58; 95% confidence interval [CI]: 1.15-37.8; p = 0.035). CONCLUSIONS mUS may be preferable for diagnosing prostate cancer in previously biopsy-negative patients. However, the retrospective design of this study at a single institution suggests that further research across multiple centers is warranted.

Is multiparametric MRI always needed in biopsy-naïve patients with abnormal digital rectal examination? A single-institutional experience combining clinical and micro-ultrasonography-based factors to optimize prostate cancer detection. World J Urol 2024; 42:9.

Abstract
PURPOSE To assess the diagnostic performance of microultrasound-targeted biopsy (microUSTBx) and systematic biopsy (SBx) in detecting clinically significant prostate cancer (csPCa) among men with abnormal digital rectal examination (DRE) and suspicious lesions at multiparametric magnetic resonance imaging (mpMRI), and to compare the diagnostic performance of this approach with a mpMRI-guided targeted biopsy (MTBx) plus SBx-based strategy. METHODS Biopsy-naïve men with suspicious lesions at mpMRI and abnormal DRE were prospectively evaluated between October 2017 and January 2023. csPCa detection rate by microUSTBx plus SBx and MTBx plus SBx was assessed and then compared by McNemar's test. The added value of prostate-specific antigen density (PSAd) was also evaluated. RESULTS Overall, 182 biopsy naïve men were included. MicroUSTBx plus SBx achieved comparable detection rate to MTBx plus SBx in diagnosis of ciPCa and csPCa (ciPCa: 9.3% [17/182] vs 10% [19/182]; csPCa: 63% [114/182] vs 62% [113/182]). MicroUSTBx outperformed MTBx (ciPCa: 5.5% [10/182] vs 6.0% [11/182]; csPCa: 57% [103/182] vs 54% [99/182]). Using microUSTBx plus SBx would have avoided 68/182 (37%) unnecessary mpMRI, while missing only 2/116 (1.7%) csPCa. The decision curve analysis of suspicious microUS plus PSAd ≥ 0.15 ng/ml showed higher net benefit in the ability to identify true positives and reduce the number of unnecessary prostate biopsy in this subcategory of patients. CONCLUSIONS The combination of microUSTBx and SBx showed equal diagnostic performance to an mpMRI-based approach in biopsy-naïve patients with an abnormal DRE. The combination of this approach with PSAd maximize the diagnostic accuracy while lowering the need for unnecessary biopsies.

Abstract
IMPORTANCE Vesicouterine fistula (VUF) is an iatrogenic consequence of cesarean section in the vast majority of cases. The worldwide increase of cesarean delivery rates is likely to be accompanied by a rise of this complication, and surgery is the mainstay treatment. OBJECTIVE The aim of the study is to assess current evidence on VUF pathogenesis and management. STUDY DESIGN The study is a case report and literature review on PubMed and Embase spanning over the past 2 decades. RESULTS An early VUF developed after a cesarean section at full cervical dilation and concurrent incidental bladder injury. A transabdominal extravesical repair was performed 3 months after cesarean delivery. Both the cystotomy and hysterotomy were repaired in a double-layer fashion with no interposition flap. A contemporary literature review including 25 patients showed that VUF was repaired transabdominally in 21 patients (84%), and an open approach was adopted in 18 patients (85.7%). In most patients, the uterine side was closed with a single-layer suture and an interposition flap was used to reinforce the repair. Concomitant hysterectomy was performed in 6 patients (24%). Overall, successful term pregnancies were reported in 2 patients after VUF repair. CONCLUSIONS Vesicouterine fistula is a rare event and is commonly associated with cesarean sections, especially those with a concurrent bladder injury. Careful and meticulous surgical technique may prevent the occurrence of this condition. Delayed repair and double-layer closure of both bladder and uterus, with or without an interposition flap, are recommended.

Abstract
OBJECTIVE To create and validate 2 models called RENSAFE (RENalSAFEty) to predict postoperative acute kidney injury (AKI) and development of chronic kidney disease (CKD) stage 3b in patients undergoing partial (PN) or radical nephrectomy (RN) for kidney cancer. METHODS Primary objective was to develop a predictive model for AKI (reduction >25% of preoperative eGFR) and de novo CKD≥3b (<45 ml/min/1.73m2), through stepwise logistic regression. Secondary outcomes include elucidation of the relationship between AKI and de novo CKD≥3a (<60 ml/min/1.73m2). Accuracy was tested with receiver operator characteristic area under the curve (AUC). RESULTS AKI occurred in 452/1,517 patients (29.8%) and CKD≥3b in 116/903 patients (12.8%). Logistic regression demonstrated male sex (OR = 1.3, P = 0.02), ASA score (OR = 1.3, P < 0.01), hypertension (OR = 1.6, P < 0.001), R.E.N.A.L. score (OR = 1.2, P < 0.001), preoperative eGFR<60 (OR = 1.8, P = 0.009), and RN (OR = 10.4, P < 0.0001) as predictors for AKI. Age (OR 1.0, P < 0.001), diabetes mellitus (OR 2.5, P < 0.001), preoperative eGFR <60 (OR 3.6, P < 0.001) and RN (OR 2.2, P < 0.01) were predictors for CKD≥3b. AUC for RENSAFE AKI was 0.80 and 0.76 for CKD≥3b. AKI was predictive for CKD≥3a (OR = 2.2, P < 0.001), but not CKD≥3b (P = 0.1). Using 21% threshold probability for AKI achieved sensitivity: 80.3%, specificity: 61.7% and negative predictive value (NPV): 88.1%. Using 8% cutoff for CKD≥3b achieved sensitivity: 75%, specificity: 65.7%, and NPV: 96%. CONCLUSION RENSAFE models utilizing perioperative variables that can predict AKI and CKD may help guide shared decision making. Impact of postsurgical AKI was limited to less severe CKD (eGFR<60 ml/min 71.73m2). Confirmatory studies are requisite.

Male awareness of prostate cancer risk remains poor in relatives of women with germline variants in DNA-repair genes. BJUI COMPASS 2023; 4:738-745.

Abstract
Abstract. Objective The aim of this study is to evaluate male awareness of developing prostate cancer (PCa) in families with germline DNA-repair genes (DRG) variants. Materials and methods Data were collected from a prospective, monocentric cohort study. The study was conducted in a university hospital with a multidisciplinary approach to the patient (collaboration of the Departments of Oncology, Urology, Pathology, Radiology, and Medical Genetics Laboratory). We recruited healthy males, relatives of families of women with breast or ovarian cancer who tested positive for pathogenic variants (PVs) or likely pathogenic variants (LPVs) in DRGs. A dedicated PCa screening was designed and offered to men aged 35 to 69 years, based on early visits with digital rectal examination (DRE), prostate health index (PHI) measurement, multiparametric magnetic resonance imaging (mpMRI) and, if necessary, targeted/systematic prostate biopsies. The primary endpoint was to evaluate the willingness of healthy men from families with a DRG variants detected in female relatives affected with breast and/or ovarian cancer to be tested for the presence of familial PVs. The secondary endpoints were the acceptance to participate if resulted positive and compliance with the screening programme. Results Over 1256 families, of which 139 resulted positive for PVs in DRGs, we identified 378 'healthy' men aged between 35 and 69 years old. Two hundred sixty-one (69.0%) refused to be tested for DRG variants, 66 (17.5%) declared to have been previously tested, and 51 (13.5%) males were interested to be tested. Between those previously tested and those who accepted to be tested, 62 (53.0%) were positive for a DRG variant, and all of them accepted to participate in the subsequent surveillance steps. The main limitation is that is a single-centre study and a short follow-up. Conclusions All men tested positive for a DRG variants agreed to go under the surveillance scheme. However, only 31% of 'men at risk' (i.e., relative of a DRG variant carrier) expressed their willingness to be tested for the familial DRG variant. This observation strongly supports the urgent need to implement awareness of genetic risk for PCa within the male population.

Abstract
PURPOSE We sought to determine if the International Bladder Cancer Group IR-NMIBC (Intermediate-risk Nonmuscle-invasive Bladder Cancer) scoring system can predict the requirement of delayed transurethral resection of bladder tumor in low-grade nonmuscle-invasive bladder cancer managed by active surveillance. MATERIALS AND METHODS We prospectively studied recurrent low-grade Ta/T1 nonmuscle-invasive bladder cancer patients managed with active surveillance with the following characteristics: low-grade papillary nonmuscle-invasive bladder cancer, ≤5 apparent low-grade nonmuscle-invasive bladder tumors, tumor diameter ≤1 cm, absence of gross hematuria, and negative urinary cytology. Subsequent transurethral resection of bladder tumor was offered to patients who no longer met the inclusion criteria or patient choice. The ability of the International Bladder Cancer Group IR-NMIBC scoring system to predict receipt of subsequent transurethral resection of bladder tumor was determined. Multivariable Cox proportional hazards analysis was used to determine factors associated with subsequent transurethral resection of bladder tumor. RESULTS A total of 163 patients with low-grade Ta/T1 nonmuscle-invasive bladder cancer were included for analysis. After a median follow-up of 33 months (IQR: 21-46), transurethral resection of bladder tumor was performed on 109 patients. At landmark time point of 24 months, patients with 0 risk factors were over 2-fold more likely to continue active surveillance compared to patients with ≥3 risk factors (59% vs 24%). Multivariable Cox regression suggested that the International Bladder Cancer Group IR-NMIBC scoring system was associated with subsequent transurethral resection of bladder tumor (1-2 risk factors [HR: 1.66, 95% CI: 0.96-2.90, P = .072], ≥3 risk factors [HR: 3.21, 95% CI: 1.70-6.09, P < .001]) after adjusting for age, T stage, and sex. CONCLUSIONS The International Bladder Cancer Group IR-NMIBC scoring system can predict the risk of subsequent transurethral resection of bladder tumor in patients with low-grade nonmuscle-invasive bladder cancer on active surveillance.

Diagnostic accuracy of multiparametric MRI- and microultrasound-targeted biopsy in biopsy-naïve patients with a PI-RADS 5 lesion: a single-institutional study. World J Urol 2023; 41:2335-2342. [PMID: 37418017 DOI: 10.1007/s00345-023-04480-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2023] [Accepted: 06/02/2023] [Indexed: 07/08/2023] Open
Abstract
PURPOSE To evaluate the diagnostic accuracy of multiparametric magnetic resonance imaging (MRI)- and microultrasound (microUS)-guided targeted biopsy (TBx) in detecting prostate cancer (PCa) and clinically significant (cs) PCa among men with Prostate Imaging Reporting and Data System (PI-RADS 5) lesions and to compare this combined TBx (CTBx) strategy with CTBx plus systemic biopsy (SBx). METHODS One hundred and thirty-six biopsy-naïve patients with PI-RADS 5 lesion at multiparametric MRI undergoing CTBx plus SBx were retrospectively evaluated. Analysis of diagnostic performance of microUS-TBx, MRI-TBx, CTBx, SBx and combined CTBx plus SBx was performed. Cost (downgrade, upgrade and biopsy core) to effectiveness (detection rate) was compared. RESULTS CTBx achieved a comparable detection rate to CTBx plus SBx in diagnosis of PCa and csPCa (PCa: 78.7% [107/136] vs 79.4% [108/136]; csPCa: 67.6% [92/136] vs 67.6% [92/136]; p > 0.05) and outperformed SBx (PCa: 58.8% [80/136]; csPCa: 47.8% [65/136]; p < 0.001). Using CTB would have avoided 41.1% (56/136) unnecessary SBx, without missing any csPCa. The rate of any upgrading or csPCa upgrading was significantly higher by SBx than by CTBx [33/65 (50.8%) vs 17/65 (26.1%) and 20/65 (30.8%) vs 4/65 (6.15%), respectively, p < 0.05]. Considering csPCa detection rate, microUS showed high sensitivity and positive predictive value (94.6%, 87.9%, respectively), with lower specificity and negative predictive value (25.0% and 44.4%, respectively). At multivariable logistic regression models, positive microUS was identified as an independent predictor of csPCa (p = 0.024). CONCLUSIONS A combined microUS/MRI-TBx approach could be the ideal imaging tool for characterizing primary disease in PI-RADS five patients, allowing SBx to be avoided.

Is It Time to Anticipate the Use of PARP Inhibition in Prostate Cancer Patients? Curr Oncol 2023; 30:8054-8067. [PMID: 37754499 PMCID: PMC10528501 DOI: 10.3390/curroncol30090584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Revised: 08/28/2023] [Accepted: 08/29/2023] [Indexed: 09/28/2023] Open
Abstract
The increasing diffusion of genetic analysis regarding the pathogenetic variants (PVs) of genes involved in DNA Damage Repair (DDR) mechanisms and the development of Poly ADP ribose polymerase (PARP) inhibitors (PARPis) led to the first valid precision medicine option tailored toward metastatic prostate cancer (mPC). The concept of anticipation in the systemic treatment of mPC was initially adopted for androgen receptor signaling inhibitors (ARSIs) to describe the expansion of their indications, from the setting of the late-stage second-line treatment of metastatic castration-resistant prostate cancer (mCRPC) to first-line therapy in selected cases. There is already mounting evidence in favor of the anticipation of PARPis in the first line of mCRPC therapy, and further evidence in favor of mHSPC is emerging. Many studies have demonstrated the synergism between ARSIs and PARP inhibitors. Recent discoveries regarding the crosstalk between the androgen receptor (AR) and DNA repair mechanisms are disconnecting the use of PARPis from genetic analysis. The new message emerging is that the combination of PARPis with ARSIs may work independently of DDR mutational status. As a matter of fact, most of the recent trials analyzing the combination of PARPis with abiraterone or enzalutamide as a first-line therapy enrolled mCRPC patients irrespective of their mutational status. The PROPEL trial concluded that the advantage of the combination was independent of PV status, despite a higher advantage being reported in the BRCA1/2 mutated subgroup. The MAGNITUDE trial, however, showed a significant advantage only in the DDR mutated subgroup, and the DDR non-mutated cohort was closed for further enrollment. The combination of PARPis with ARSIs represents a significant strategy with a view to the anticipation and intensification of care in mPC. However, it should not nullify the advantages of precision medicine linked to the genetic analysis of DDR genes.

Same-day discharge for endoscopic enucleation of the prostate: a systematic review and meta-analysis. World J Urol 2023; 41:2099-2106. [PMID: 37395755 DOI: 10.1007/s00345-023-04471-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Accepted: 05/31/2023] [Indexed: 07/04/2023] Open
Abstract
PURPOSE To systematically review studies focused on the feasibility and outcomes of outpatient endoscopic enucleation of the prostate for benign prostatic obstruction. METHODS A literature search was conducted through December 2022 using PubMed/Medline, Web of Science, and Embase databases. Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed to identify eligible studies. Risk of bias assessment was performed according to the Newcastle-Ottawa Scale for case control studies. RESULTS Of 773 studies, ten were included in the systematic review (n = 1942 patients) and four in the meta-analysis (n = 1228 patients). The pooled incidence of successful same-day discharge was 84% (95% CI 0.72-0.91). Unplanned readmission was recorded in 3% (95% CI 0.02-0.06) of ambulatory cases. In the reported criteria-selected patients submitted to SDD surgery, the forest plot suggested a lower rate of postoperative readmission (OR 0.56, 95% CI 0.34-0.91, p = 0.02) and complications (OR 0.69, 95% CI 0.48-1, p < 0.05) rates compared to standard protocols. CONCLUSION We provide the first systematic review and meta-analysis on SDD for endoscopic prostate enucleation. Despite the lack of randomized controlled trials, we confirm the feasibility and safety of the protocol with no increase in complications or readmission rate in well-selected patients.

Abstract
BACKGROUND T1 high-grade (HG) non-muscle invasive bladder cancer (NMIBC) has a significant risk of recurrence and progression, and the European Association of Urology recommends a second transurethral resection of the bladder (ReTUR). Stage at ReTUR has been shown to be a reliable predictor of survival, therefore, we sought to assess clinical and pathological predictors associated with the persistence of T1 at ReTUR in our retrospective multicentric cohort. METHODS This is a retrospective multicentric study of T1 HG patients at transurethral resection of the bladder (TURB) who underwent subsequent ReTUR. All histological samples were sub-classified according to Rete Oncologica Lombarda (ROL) T1 sub-staging system. RESULTS One hundred and sixty-six patients were enrolled. Forty-four (26.5%) had T1 HG tumor at ReTUR while 93 (56%) had residual tumor of any stage. Lesion size was significantly greater in T1 HG patients at ReTUR, as well as the prevalence of multifocality. The multivariable logistic regression model showed lesion dimension and multifocality as predictors of T1 HG at ReTUR, after adjusting for significant covariables (CIS and detrusor muscle presence). ROL sub-staging system was not a significant predictor, but ROL2 prevalence was higher in the T1 HG at ReTUR group. CONCLUSIONS Lesion size and multifocality were independent predictors of T1 HG persistence at ReTUR, and patients at risk should be promptly identified and treated accordingly. Our results could help physicians make patient-tailored decisions by identifying those most likely to benefit from a second resection.

Evaluation of Semen Self-Sampling Yield Predictors and CTC Isolation by Multi-Color Flow Cytometry for Liquid Biopsy of Localized Prostate Cancer. Cancers (Basel) 2023; 15:2666. [PMID: 37345004 DOI: 10.3390/cancers15102666] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 05/01/2023] [Accepted: 05/06/2023] [Indexed: 06/23/2023] Open
Abstract
Liquid biopsy (LB) for prostate cancer (PCa) detection could represent an alternative to biopsy. Seminal fluid (SF) is a source of PCa-specific biomarkers, as 40% of ejaculate derives from the prostate. We tested the feasibility of an SF-based LB by evaluating the yield of semen self-sampling in a cohort of >750 patients with clinically localized PCa. The overall SF collection yield was 18.2% (39% when considering only compliant patients), with about a half of the patients (53.15%) not consenting to SF donation. Independent favorable predictors for SF collection were younger age and lower prostate volume. We implemented a protocol to enrich prostate-derived cells by multi-color flow cytometry and applied it on SF and urine samples from 100 patients. The number of prostate-enriched cells (SYTO-16+ PSMA+ CD45-) was variable, with higher numbers of cells isolated from SF than urine (p value < 0.001). Putative cancer cells (EpCAMhigh) were 2% of isolated cells in both specimens. The fraction of EpCAMhigh cells over prostate-enriched cells (PSMA+) significantly correlated with patient age in both semen and urine, but not with other clinical parameters, such as Gleason Score, ISUP, or TNM stage. Hence, enumeration of prostate-derived cells is not sufficient to guide PCa diagnosis; additional molecular analyses to detect patient-specific cancer lesions will be needed.

Abstract
BACKGROUND Active surveillance (AS) represents a standard of care of low-risk prostate cancer (PCa). However, identification and monitoring of AS candidates remains challenging. Micro-ultrasound (microUS) is a novel high-resolution imaging modality for transrectal ultrasonography (TRUS). We explored the impact of microUS TRUS and targeted biopsies in mpMRI-guided confirmatory biopsies. METHODS Between October 2017 and September 2021 we prospectively enrolled 100 patients scheduled for MRI-guided confirmatory biopsy at 1 year from diagnosis of ISUP 1 PCa. TRUS was performed using the ExactVu microUS system; PRI-MUS protocol was applied to identify suspicious lesions (i.e. PRIMUS score ≥3). All patients received targeted biopsies of any identified microUS and mpMRI lesions and complementary systematic biopsies. The proportion of patients upgraded to clinically significant PCa (defined as ISUP≥2 cancer; csPCa) at confirmatory biopsies was determined, and the diagnostic performance of microUS and mpMRI were compared. RESULTS 92 patients had a suspicious MRI lesion classified PI-RADS 3, 4 and 5 in respectively 28, 16 and 18 patients. MicroUS identified 82 patients with suspicious lesions, classified as PRI-MUS 3, 4 and 5 in respectively 20, 50 and 12 patients, while 18 individuals had no lesions. 34 patients were upgraded to ISUP≥2 cancer and excluded from AS. MicroUS and mpMRI showed a sensitivity of 94.1% and 100% and a NPV of 88.9% and 100% respectively in detecting ISUP≥2 patients. A microUS-mandated protocol would have avoided confirmatory biopsies in 18 patients with no PRI-MUS ≥3 lesions at the cost of missing 4 upgraded patients. CONCLUSIONS MicroUS and mpMRI represent valuable imaging modalities showing high sensitivity and NPV in detecting csPCa, thus allowing their use for event-triggered confirmatory biopsies in AS patients. MicroUS offers an alternative imaging modality to mpMRI for the identification and real-time targeting of suspicious lesions in AS patients. This article is protected by copyright.

Evaluating the Protective Effect of Intravesical Bacillus Calmette-Guerin against SARS-CoV-2 in Non-Muscle Invasive Bladder Cancer Patients: A Multicenter Observational Trial. Cancers (Basel) 2023; 15:cancers15051618. [PMID: 36900409 PMCID: PMC10000457 DOI: 10.3390/cancers15051618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 02/17/2023] [Accepted: 02/24/2023] [Indexed: 03/08/2023] Open
Abstract
We aim to evaluate the potential protective role of intravesical Bacillus Calmette-Guerin (BCG) against SARS-CoV-2 in patients with non-muscle invasive bladder cancer (NMIBC). Patients treated with intravesical adjuvant therapy for NMIBC between January 2018 and December 2019 at two Italian referral centers were divided into two groups based on the received intravesical treatment regimen (BCG vs. chemotherapy). The study's primary endpoint was evaluating SARS-CoV-2 disease incidence and severity among patients treated with intravesical BCG compared to the control group. The study's secondary endpoint was the evaluation of SARS-CoV-2 infection (estimated with serology testing) in the study groups. Overall, 340 patients treated with BCG and 166 treated with intravesical chemotherapy were included in the study. Among patients treated with BCG, 165 (49%) experienced BCG-related adverse events, and serious adverse events occurred in 33 (10%) patients. Receiving BCG or experiencing systemic BCG-related adverse events were not associated with symptomatic proven SARS-CoV-2 infection (p = 0.9) nor with a positive serology test (p = 0.5). The main limitations are related to the retrospective nature of the study. In this multicenter observational trial, a protective role of intravesical BCG against SARS-CoV-2 could not be demonstrated. These results may be used for decision-making regarding ongoing and future trials.

Abstract
BACKGROUND Patients with multiple ipsilateral renal masses have an augmented risk of metachronous contralateral lesions and are likely to undergo repeated surgeries. We report our experience with the technologies currently available and the surgical techniques to preserve healthy parenchyma while guaranteeing oncological radicality during robot-assisted partial nephrectomy (RAPN). METHODS The data were collected at three tertiary-care centers, where 61 patients with multiple ipsilateral renal masses were treated with RAPN between 2012 and 2021. RAPN was performed with da Vinci Si or Xi surgical system using TilePro (Life360; San Francisco, CA, USA), indocyanine green fluorescence and intraoperative ultrasound. Three-dimensional reconstructions were built in some cases preoperatively. Different techniques were employed for hilum management. The primary endpoint is to report intra- and postoperative complications. Secondary endpoints were the estimated blood loss (EBL), warm ischemia time (WIT) and positive surgical margins (PSM) rate. RESULTS Median preoperative size of the largest mass was 37.5 mm (24-51) with a median PADUA and R.E.N.A.L. score of 8 (7-9) and 7 (6-9). One hundred forty-two tumors were excised, with a mean number of 2.32. The median WIT was 17 (12-24) minutes, and the median EBL was 200 (100-400) mL. Intraoperative ultrasound was employed in 40 (67.8%) patients. The rate of early unclamping, selective clamping and zero-ischemia were respectively 13 (21.3%), 6 (9.8%) and 13 (21.3%). ICG fluorescence was employed in 21 (34.42%) patients and three-dimensional reconstructions were built in 7 (11.47%) patients. Three (4.8%) intraoperative complications occurred, all classified as grade-1 according to EAUiaiC. Postoperative complications were reported in 14 (22.9%) cases with 2 Clavien-Dindo grade >2 complications. Four (6.56%) patients had PSM. Mean period of follow-up was 21 months. CONCLUSIONS In experienced hands, with the employment of the currently available technologies and surgical techniques, RAPN can guarantee optimal outcomes in patients with multiple ipsilateral renal masses.

Is Segmental Ureterectomy Associated with Inferior Survival for Localized Upper-Tract Urothelial Carcinoma of the Ureter Compared to Radical Nephroureterectomy? Cancers (Basel) 2023; 15:cancers15051373. [PMID: 36900166 PMCID: PMC10000204 DOI: 10.3390/cancers15051373] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2022] [Revised: 02/08/2023] [Accepted: 02/14/2023] [Indexed: 02/24/2023] Open
Abstract
Segmental ureterectomy (SU) is an alternative to radical nephroureterectomy (RNU) in the treatment of upper-tract urothelial carcinoma (UTUC) of the ureter. SU generally preserves renal function, at the expense of less intensive cancer control. We aim to assess whether SU is associated with inferior survival compared to RNU. Using the National Cancer Database (NCDB), we identified patients diagnosed with localized UTUC of the ureter between 2004-2015. We used a propensity-score-overlap-weighted (PSOW) multivariable survival model to compare survival following SU vs. RNU. PSOW-adjusted Kaplan-Meier curves were generated and we performed a non-inferiority test of overall survival. A population of 13,061 individuals with UTUC of the ureter receiving either SU or RNU was identified; of these, 9016 underwent RNU and 4045 SU. Factors associated with decreased likelihood of receiving SU were female gender (OR, 0.81; 95% CI, 0.75-0.88; p < 0.001), advanced clinical T stage (cT4) (OR, 0.51; 95% CI, 0.30-0.88; p = 0.015), and high-grade tumor (OR, 0.76; 95% CI, 0.67-0.86; p < 0.001). Age greater than 79 years was associated with increased probability of undergoing SU (OR, 1.18; 95% CI, 1.00-1.38; p = 0.047). There was no statistically significant difference in OS between SU and RNU (HR, 0.98; 95% CI, 0.93-1.04; p = 0.538). SU was not inferior to RNU in PSOW-adjusted Cox regression analysis (p < 0.001 for non-inferiority). In weighted cohorts of individuals with UTUC of the ureter, the use of SU was not associated with inferior survival compared to RNU. Urologists should continue to utilize SU in appropriately selected patients.

Abstract
328 Background: Although one of the most important risk factors for prostate cancer (PCa) is a family history of the disease, there is a poor awareness of genetic risk. The aim of the current study is to investigate the awareness of genetic risk for PCa in men belonging to female families with germline variants in DNA-repair genes (DRGs). Methods: Data were extracted by a prospective observational study designed to select men with germline pathogenic variants (PVs) and offer them a dedicated PCa screening. The selection of probands was performed by genetic counseling and testing of male grade I relatives of female patients with a PVs. Male candidates were identified after reviewing the genealogical trees of all women who had received the diagnosis of breast and/or ovarian cancer and tested positive for a PVs. All the probands, 35-69 yrs old, who resulted positive for PVs were offered to participate to a specific PCa screening based on annually digital rectal examination (DRE), detection of PHI, which is a blood test including total PSA, free PSA, free/total PSA and -2proPSA, and multiparametric MRI. The primary outcome was the “willing to be tested”, defined as a proxy for male awareness of PCa risk. The secondary endpoint was the acceptance rate to be screened. Results: We reviewed the genealogical trees of breast/ovarian cancer female patients from January 2017 to December 2021 and we identified, over 1256 families, 139 positive cases for PVs in DRGs. Among 139 families, we identified 378 “healthy” 35-69 yrs old men, who were offered a genetic counseling, and if they agree a genetic testing. Overall 117/378 (31%) healthy males declared to be interested to be tested. Out of the 51 new tests (66 men already tested out of the study), we found 30 (58.8%) positive men. All the new positive tested men accepted to attend the PCa screening. Living in Northern Italy, having at least one child and higher (degree) level of education were the strongest predictors of willing for testing (p<0.01). Conclusions: Our data reveals a limited will to be tested, but all men tested positive for PVs accepted to participate to the PCa screening. These findings strongly support the urgent need to implement awareness of genetic risk for PCa.

Abstract
TPS578 Background: Approximately 75-85% of vesical urothelial carcinomas are non-muscle invasive bladder cancers (NMIBC). The primary treatment is transurethral resection (TUR) followed by adjuvant intravesical therapies with immunotherapy (BCG) and/or chemotherapy agents (i.e. mitomycin C - MMC). Unfortunately, the response to intravesical treatments is variable and incomplete and there is a un-met clinical need to improve its efficacy for reducing the recurrence rate and progression to muscle invasive BC (MIBC). Recently, has been showed that MMC induces immunogenic cell death (ICD), determining the expression of specific damage signals, like HMGB1 molecule, that favors the phagocytosis of dying tumor cells, the activation of innate immune cells and the presentation of tumor antigens to T lymphocytes [1]. The identification of ICD as a novel immune-related mechanism of action of MMC could provide opportunities to optimize bladder cancer management by proposing the use of MMC in a “neoadjuvant” setting. The aim of current clinical trial is to test the hypothesis that the neoadjuvant instillation of MMC in patients with NMIBC may reduce the recurrence rate and/or progression to MIBC. Methods: This is a prospective phase III randomized clinical trial in patients with primary treatment-naïve NMIBC recruiting since March 2022 (EudraCT 2021-003751-42_studio ICH-013-MMC). Patients are randomized 1:1 to neo-adjuvant MMC or standard of care. Patients enrolled in the neo-MMC group receive two intravesical instillations of MMC (40 mg/40 ml saline) in the 2 weeks before (days: -14 and -7) the scheduled TUR (day: 0). After TUR, as for clinical practice, both controls and neoMMC subjects, undergo adjuvant treatment, if required, based on the histological evaluation of the tumor and following EAU/PMID: 33040478 guidelines. The primary endpoint of the study is to evaluate the efficacy of MMC neoadjuvant treatment in reducing the recurrence rate of BC calculated as the proportion of patients who achieve a complete response (no evidence of BC after 3, 6, 12 and 24 mo.). The secondary clinical endpoint will be the analysis of the rate of grade and stage progression to MIBC in case of recurrence and the correlation with specific biomarker (i.e. expression of HMGB1). Consider that the primary aim of the study is to see a reduction of relapse, leading to an HR of 0.6, estimating on the control group a 30% relapse free at 12 months. With equal-sized group, a two-sided significance level test (α =0.05) with power 80% power (β=0.2), and assume that recruitment was to be terminated after 12 months, with a 2-year follow up, the required sample size is approximate 160 patient, 80 in each group (control / neoMMC).

Abstract
BACKGROUND This prospective single-arm study is designed to compare in parallel 68Ga-PSMA PET/TRUS (transrectal or transperineal) fusion biopsy ("experimental test") with multiparametric MRI (mpMRI)/TRUS fusion prostate biopsy ("standard test") in men with a high suspicion of prostate cancer (PCa) after at least one negative biopsy. The primary objective was to evaluate the diagnostic performance of 68Ga-PSMA PET/TRUS fusion prostate biopsy in comparison to mpMRI/TRUS fusion prostate biopsy analyzed in parallel. Secondarily, we aimed to determine the relationship between the "experimental test" and the histopathological characteristics of the specimen, along with the clinical utility of the "experimental test" compared to the "standard test." SUMMARY To test the superiority of 68Ga-PSMA PET/CT compared to mpMRI, we will enroll a minimum cohort of 128 patients. Inclusion criteria comprise: age >18 years; blood PSA level >4.0 ng/mL; free-to-total PSA ratio <20%; progressive rise of PSA levels in two consecutive blood samples despite antibiotics; serum blood tests suspicious for PCa; at least one previous negative biopsy; ASAP and/or high-grade PIN; negative digital rectal examination. All eligible patients will undergo 68Ga-PSMA PET/CT and mpMRI scans within 1 month's distance from each other, followed by biopsy session to be completed within 1 month's distance. Targeted TRUS fusion needle biopsy will be performed for all lesions detected with PET and mpMRI. The total duration of the study is 36 months. KEY MESSAGES By comparing the "experimental test" and the "standard test" in parallel, we will be able to determine the superior diagnostic performance of 68Ga-PSMA PET/CT over mpMRI in detecting PCa, and in particular clinically significant PCa, in the specific cohort of patients with a high suspicion of PCa who are candidates to re-biopsy. The clinical impact of the "experimental test" will be subsequently analyzed in terms of the number of prostate biopsies that could be spared, time-consuming, patient friendliness, and cost-effectiveness.

How the Analysis of the Pathogenetic Variants of DDR Genes Will Change the Management of Prostate Cancer Patients. Int J Mol Sci 2022; 24:ijms24010674. [PMID: 36614122 PMCID: PMC9821239 DOI: 10.3390/ijms24010674] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 12/20/2022] [Accepted: 12/22/2022] [Indexed: 01/03/2023] Open
Abstract
Herein, we analyze answers achieved, open questions, and future perspectives regarding the analysis of the pathogenetic variants (PV) of DNA damage response (and repair) (DDR) genes in prostate cancer (PC) patients. The incidence of PVs in homologous recombination repair (HRR) genes among men with metastatic PC varied between 11% and 33%, which was significantly higher than that in non-metastatic PC, and BRCA2 mutations were more frequent when compared to other DDR genes. The determination of the somatic or germline PVs of BRCA2 was able to define a tailored therapy using PARP inhibitors in metastatic castration-resistant prostate cancer (mCRPC) progression after first-line therapy, with significant improvements in the radiologic progression-free survival (rPFS) and overall survival (OS) rates. We propose testing all metastatic PC patients for somatic and germline HRR mutations. Somatic determination on the primary site or on historic paraffin preparations with a temporal distance of no longer than 5 years should be preferred over metastatic site biopsies. The prognostic use of DDR PVs will also be used in selected high-risk cases with non-metastatic stages to better arrange controls and therapeutic primary options. We anticipate that the use of poly-ADP-ribose polymerase (PARP) inhibitors in hormone-sensitive prostate cancer (HSPC) and in combination with androgen receptor signaling inhibitors (ARSI) will be new strategies.

Abstract
BACKGROUND Prediction of complications and surgical outcomes is of outmost importance even in patients with benign renal masses. The aim of our study is to test the PADUA, SPARE and R.E.N.A.L. scores to predict nephron sparing surgery (NSS) outcomes in patients presenting with renal angiomyolipoma (RAML). METHODS We retrospectively analyzed the clinical and pathological data of 93 patients with AML treated with robot-assisted partial nephrectomy (RAPN) at three tertiary care referral centers. Renal masses were classified according to the PADUA, SPARE and R.E.N.A.L. nephrometry scores. Surgical success was defined according to the novel Trifecta Score. Logistic regression models (LRM) were fitted to predict the achievement of novel Trifecta and the risk of high-grade Clavien-Dindo (CD) complication. The receiver operating characteristics (ROC) curve analysis was used to estimate the accuracy of LRMs. RESULTS Of 93 patients, 66 (69.9%) were females; median tumor size was 42 (36-48) mm. Novel Trifecta was achieved in 79 patients (84.9%) and postoperative complications classified as CD>2 occurred in 7 (7.5%) patients. At univariate and multivariate LRMs all three nephrometry scores were significantly associated with novel Trifecta achievement. Similar findings were observed for the prediction of CD>2 complications. The AUCs to predict optimal surgical outcomes and CD>2 complications were 0.791 and 0.912 for PADUA, 0.767 and 0.836 for SPARE and 0.756 and 0.842 for RENAL Score, respectively. CONCLUSIONS RAPN appears to be a feasible and safe surgical technique for the treatment of RAML. PADUA, SPARE and RENAL scores can be safely adopted to predict surgical outcomes, with the first one showing a higher accuracy.
