Transperineal laser ablation of the prostate as a treatment for benign prostatic hyperplasia and prostate cancer: The results of a Delphi consensus project.

Objective: To evaluate transperineal laser ablation (TPLA) with Echolaser® (Echolaser® TPLA, Elesta S.p.A., Calenzano, Italy) as a treatment for benign prostatic hyperplasia (BPH) and prostate cancer (PCa) using the Delphi consensus method. Methods: Italian and international experts on BPH and PCa participated in a collaborative consensus project. During two rounds, they expressed their opinions on Echolaser® TPLA for the treatment of BPH and PCa answering online questionnaires on indications, methodology, and potential complications of this technology. Level of agreement or disagreement to reach consensus was set at 75%. If the consensus was not achieved, questions were modified after each round. A final round was performed during an online meeting, in which results were discussed and finalized. Results: Thirty-two out of forty invited experts participated and consensus was reached on all topics. Agreement was achieved on recommending Echolaser® TPLA as a treatment of BPH in patients with ample range of prostate volume, from <40 mL (80%) to >80 mL (80%), comorbidities (100%), antiplatelet or anticoagulant treatment (96%), indwelling catheter (77%), and strong will of preserving ejaculatory function (100%). Majority of respondents agreed that Echolaser® TPLA is a potential option for the treatment of localized PCa (78%) and recommended it for low-risk PCa (90%). During the final round, experts concluded that it can be used for intermediate-risk PCa and it should be proposed as an effective alternative to radical prostatectomy for patients with strong will of avoiding urinary incontinence and sexual dysfunction. Almost all participants agreed that the transperineal approach of this organ-sparing technique is safer than transrectal and transurethral approaches typical of other techniques (97% of agreement among experts). Pre-procedural assessment, technical aspects, post-procedural catheterization, pharmacological therapy, and expected outcomes were discussed, leading to statements and recommendations. Conclusion: Echolaser® TPLA is a safe and effective procedure that treats BPH and localized PCa with satisfactory functional and sexual outcomes.

Case report: PSMA PET/CT addresses the correct diagnosis in a patient with metastatic prostate cancer despite negative core biopsies and mpMRI. A diagnostic challenge.

This is a case of [68 Ga]Ga-Prostate-specific membrane antigen (PSMA)-11 PET/CT in a 73-years old patient presenting high Prostate Specific Antigen (PSA) levels despite both multi-parametric magnetic resonance imaging (mpMRI) and 12-core saturation biopsy negative for prostate cancer (Pca). This is a highly interesting case because, despite the advanced metastatic spread at initial presentation as showed by [68Ga]Ga-PSMA-PET/CT, the primary Pca was detected by none of the diagnostic techniques (12 random sample biopsy, mpMRI, PSMA PET/CT). However, [68Ga]Ga-PSMA-PET/CT showed a suspicious axillary lesion suitable for biopsy, which finally resulted as Pca metastasis. This case report is therefore a brilliant example of how [68Ga]Ga-PSMA-PET/CT optimized patient's management.

Twenty Years' Experience in Retroperitoneal Lymph Node Dissection for Testicular Cancer in a Tertiary Referral Center.

Background and Objectives: The aim of this article is to present a single-surgeon, open retroperitoneal lymph node dissection (RPLND) series for testicular cancer in a high-volume center. Materials and Methods: We reviewed data from patients who underwent RPLND performed by an experienced surgeon at our institution between 2000 and 2019. We evaluated surgical and perioperative outcomes, complications, Recurrence-Free Survival (RFS), Overall Survival (OS), and Cancer-Specific Survival (CSS). Results: RPLND was performed in primary and secondary settings in 21 (32%) and 44 (68%) patients, respectively. Median operative time was 180 min. Median hospital stay was 6 days. Complications occurred in 23 (35%) patients, with 9 (14%) events reported as Clavien grade ≥ 3. Patients in the primary RPLND group were significantly younger, more likely to have NSGCT, had higher clinical N0 and M0, and had higher nerve-sparing RPLND (all p ≤ 0.04) compared to those in the secondary RPLND group. In the median follow-up of 120 (56-180) months, 10 (15%) patients experienced recurrence. Finally, 20-year OS, CSS, and RFS were 89%, 92%, and 85%, respectively, with no significant difference in survival rates between primary vs. secondary RPLND subgroups (p = 0.64, p = 0.7, and p = 0.31, respectively). Conclusions: Open RPLND performed by an experienced high-volume surgeon achieves excellent oncological and functional outcomes supporting the centralization of these complex procedures.

3D renal model for surgical planning of partial nephrectomy: A way to improve surgical outcomes.

Objective: to evaluate the impact of 3D model for a comprehensive assessment of surgical planning and quality of partial nephrectomy (PN). Materials and methods: 195 patients with cT1-T2 renal mass scheduled for PN were enrolled in two groups: Study Group (n= 100), including patients referred to PN with revision of both 2D computed tomography (CT) imaging and 3D model; Control group (n= 95), including patients referred to PN with revision of 2D CT imaging. Overall, 20 individuals were switched to radical nephrectomy (RN). The primary outcome was the impact of 3D models-based surgical planning on Trifecta achievement (defined as the contemporary absence of positive surgical margin, major complications and ≤30% postoperative eGFR reduction). The secondary outcome was the impact of 3D models on surgical planning of PN. Multivariate logistic regressions were used to identify predictors of selective clamping and Trifecta's achievement in patients treated with PN (n=175). Results: Overall, 73 (80.2%) patients in Study group and 53 (63.1%) patients in Control group achieved the Trifecta (p=0.01). The preoperative plan of arterial clamping was recorded as clampless, main artery and selective in 22 (24.2%), 22 (24.2%) and 47 (51.6%) cases in Study group vs. 31 (36.9%), 46 (54.8%) and 7 (8.3%) cases in Control group, respectively (p<0.001). At multivariate logistic regressions, the use of 3D model was found to be independent predictor of both selective or super-selective clamping and Trifecta's achievement. Conclusion: 3D-guided approach to PN increase the adoption of selective clamping and better predict the achievement of Trifecta.

Novel Volumetric and Morphological Parameters Derived from Three-dimensional Virtual Modeling to Improve Comprehension of Tumor's Anatomy in Patients with Renal Cancer.

BACKGROUND: Three-dimensional (3D) models improve the comprehension of renal anatomy. OBJECTIVE: To evaluate the impact of novel 3D-derived parameters, to predict surgical outcomes after robot-assisted partial nephrectomy (RAPN). DESIGN, SETTING, AND PARTICIPANTS: Sixty-nine patients with cT1-T2 renal mass scheduled for RAPN were included. Three-dimensional virtual modeling was achieved from computed tomography. The following volumetric and morphological 3D parameters were calculated: VT (volume of the tumor); VT/VK (ratio between tumor volume and kidney volume); CSA3D (ie, contact surface area); UCS3D (contact to the urinary collecting system); Tumor-Artery3D: tumor's blood supply by tertiary segmental arteries (score = 1), secondary segmental artery (score = 2), or primary segmental/main renal artery (scoren = 3); ST (tumor's sphericity); ConvT (tumor's convexity); and Endophyticity3D (ratio between the CSA3D and the global tumor surface). INTERVENTION: RAPN with a 3D model. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Three-dimensional parameters were compared between patients with and without complications. Univariate logistic regression was used to predict overall complications and type of clamping; linear regression was used to predict operative time, warm ischemia time, and estimated blood loss. RESULTS AND LIMITATIONS: Overall, 11 (15%) individuals experienced overall complications (7.2% had Clavien ≥3 complications). Patients with urinary collecting system (UCS) involvement at 3D model (UCS3D = 2), tumor with blood supply by primary or secondary segmentary arteries (Tumor-Artery3D = 1 and 2), and high Endophyticity3D values had significantly higher rates of overall complications (all p ≤ 0.03). At univariate analysis, UCS3D, Tumor-Artery3D, and Endophyticity3D are significantly associated with overall complications; CSA3D and Endophyticity3D were associated with warm ischemia time; and CSA3D was associated with selective clamping (all p ≤ 0.03). Sample size and the lack of interobserver variability are the main limits. CONCLUSIONS: Three-dimensional modeling provides novel volumetric and morphological parameters to predict surgical outcomes after RAPN. PATIENT SUMMARY: Novel morphological and volumetric parameters can be derived from a three-dimensional model to describe surgical complexity of renal mass and to predict surgical outcomes after robot-assisted partial nephrectomy.

Percutaneous ablation or minimally invasive partial nephrectomy for cT1a renal masses? A propensity score-matched analysis.

OBJECTIVE: Local tumor ablation to treat small renal mass is increasing. The aim of the present study was to compare oncologic outcomes among patients with T1 renal mass treated with partial nephrectomy and local tumor ablation. METHODS: To reduce the inherent differences between patients undergoing laparoscopic or robot-assisted partial nephrectomy (n = 405) and local tumor ablation (n = 137), we used a 1:1 propensity score-matched analysis. Local tumor ablation consisted of radiofrequency ablation and cryoablation. Disease-free survival, overall survival and other causes mortality-free survival rates were estimated using the Kaplan-Meier method. Multivariable logistic regression and competing-risk regression models were used to identify predictors of complications, recurrence and other causes mortality, respectively. RESULTS: Partial nephrectomy had higher disease-free survival estimates, as compared with local tumor ablation (92.8% vs 80.4% at 5 years, P = 0.02), with no significant difference between radiofrequency ablation and cryoablation (P = 0.9). Ablation showed comparable overall survival estimates to partial nephrectomy (91% vs 95.8% at 5 years, P = 0.6). The 5-year recurrence rates were 7.9% versus 23.8% for patients aged ≤70 years, and 2.5% versus 11.9% for patients aged >70 years treated with partial nephrectomy and ablation, respectively; the 5-year other causes mortality rates were 0% and 2.2% for patients treated with partial nephrectomy and ablation aged ≤70 years, and 3% versus 10.9% for patients aged >70 years treated with partial nephrectomy and ablation, respectively. At multivariable analysis, ablation was associated with fewer complications (odds ratio 0.41; P = 0.01). At competing risks analysis, age (hazard ratio 0.96) and ablation (hazard ratio 4.56) were independent predictors of disease recurrence (all P ≤ 0.008). CONCLUSIONS: Local tumor ablation showed a higher risk of recurrence and lower risk of complications compared with partial nephrectomy, with comparable overall survival rates.

Interpreting nephrometry scores with three-dimensional virtual modelling for better planning of robotic partial nephrectomy and predicting complications.

OBJECTIVE: 3D models are increasingly used as additional preoperative tools for renal surgery. We aim to evaluate the impact of 3D renal models in the assessment of PADUA, RENAL, Contact Surface Area (CSA) and Arterial Based Complexity (ABC) for the prediction of complications after Robot assisted Partial Nephrectomy (RAPN). METHODS AND MATERIALS: Overall, 57 patients with T1 and 1 patient with T2 renal mass referred to RAPN, were prospectively enrolled. 3D virtual modelling was obtained from 2D computed tomography (CT). Two radiologists recorded PADUA2D, RENAL2D, CSA2D and ABC2D by evaluation of 2D images; two bioengineers recorded PADUA3D, RENAL3D, CSA3D and ABC3D by evaluation of the 3D model, using MeshMixer software. To evaluate the concordance between 2D and 3D nephrometry scores, Cohen's j coefficient was calculated. Receiver-operating characteristic (ROC) curves were generated to evaluate the accuracy of 3D and 2D nephrometry scores to predict overall complications. Finally, the impact of 3D model on clamping approach during RAPN was compared to 2D imaging. RESULTS: PADUA3D, RENAL3D, CSA3D and ABC3D scores had a significant different distribution compared to PADUA2D, RENAL2D, CSA2D and ABC2D (all p≤0.03). 2D nephrometry scores may be unchanged, reduced or increased after assessment by 3D models: CSA3D, PADUA3D, RENAL3D and ABC3D were reduced in14%, 26%, 29% and 16% and increased in 16%, 36%, 38% and 29% of cases, respectively. At ROC curve analysis, PADUA3D, RENAL3D and ABC3D showed were significantly better accuracy to predict complications compared to PADUA2D, RENAL2D and ABC2D. PADUA3D (OR: 1.66), RENAL3D (OR: 1.69) and ABC3D (OR: 2.44) revealed a significant correlation with postoperative complications (all P ≤0.03). CONCLUSION: Nephrometry scores calculated via 3D models predict complications after RAPN with higher accuracy than conventional 2D imaging.

The robotic approach improves the outcomes of ERAS protocol after radical cystectomy: A prospective case-control analysis.

BACKGROUND: Minimally-invasive approach is one of the mainstays of Enhanced Recovery After Surgery (ERAS) pathways. Robot-assisted radical cystectomy (RARC) introduction has reduced the surgical burden on patient's recovery. Accordingly, ERAS protocol benefits may be more striking in RARC patients. We evaluated the impact of surgical approach on perioperative outcomes, Fast Track (FT) recovery steps and Trifecta success rates in patients undergoing RC followed by FT protocol. MATERIALS AND METHODS: We considered 147 patients who underwent RC, with open (Open radical cystectomy [ORC]; 47.6%) or robotic (RARC; 52.4%) approach at 2 tertiary centers. Urinary diversions were ileal conduit or orthotopic neobladder. All patients underwent FT protocol. We analyzed perioperative surgical and functional outcomes and Trifecta success rates (namely, defecation <5 days, in-hospital stay <10 days and no major complications). Uni and multivariable logistic regression explored the predictors for Trifecta success and the impact of surgical approach on recovery steps. RESULTS: Patients undergoing RARC had higher FT adherence (95% vs. 61%) compared to ORCs (P < 0.01). Trifecta success rates were higher for RARC (79.2% vs 28.6%; P < 0.001). At multivariable analyses, RARC was an independent predictor for Trifecta success (OR 9.1), early mobilization (OR 5.9) and FT adherence (OR 3.33; all P < 0.001). Surgical technique was not associated with major complications or readmission within 90 days (all P > 0.05). CONCLUSION: RARC has more favorable perioperative outcomes compared to ORC, with higher Trifecta success rates. Accordingly, robotic approach should be ideally included in every center where ERAS protocol is applied to RC for maximizing patient's recovery.

Diagnostic performance of MRI/TRUS fusion-guided biopsies vs. systematic prostate biopsies in biopsy-naïve, previous negative biopsy patients and men undergoing active surveillance.

BACKGROUND: We aimed to assess the detection rate of overall PCa and csPCa, and the clinical impact of MRI/TRUS fusion targeted biopsy (FUSION-TB) compared to TRUS guided systematic biopsy (SB) in patients with different biopsy settings. METHODS: Three hundred and five patients were submitted to FUSION-TB, divided into three groups: biopsy naïve patients, previous negative biopsies and patients under active surveillance (AS). All patients had a single suspicious index lesion at mpMRI. Within these groups, we enrolled men underwent both to FUSION-TB and SB in the same session. Overall detection rate of PCa and csPCa for the two biopsy methods were compared separately between the three groups of patients. RESULTS: No differences were observed between the three groups concerning clinical and radiological characteristics. We found no differences in terms of overall PCa detection (66% vs. 63.8%, P=0.617) and csPCa detection (56.4% vs. 51.1%; P=0.225) concerning biopsy naïve patients. In patients previously submitted to a negative biopsy, FUSION-TB showed higher detection rate of csPCa compared to SB alone (41,3% vs. 27% respectively, P=0.038). In patients under AS, no differences were observed between FUSION-TB and SB in terms of overall PCa (50% vs. 73.1%) and csPCa (30.8% vs. 26.9%, respectively; P=0.705) detection. CONCLUSIONS: Our results suggest that in men with previously negative biopsy, FUSION-TB showed significantly higher diagnostic performance for clinically significant PCa as compared to SB. Combination of FUSION-TB and SB should be recommended in AS population to offer higher chance of csPCa diagnosis.

Oncologic outcomes of patients with incidental prostate cancer who underwent RARC: a comparison between nerve sparing and non-nerve sparing approach.

BACKGROUND: Incidental Prostate cancer (iPCa) is a relatively common finding during histopathological evaluation of radical cystectomy (RC) specimens. To reduce the high impact of RC on erectile function, several sexual-preserving techniques have been proposed. The aim of this study was to evaluate and compare the oncologic outcomes of patients with iPCa who underwent nerve spring and no-nerve sparing robot-assisted radical cystectomy (RARC). METHODS: The clinicopathologic data of male patients who underwent RARC at our institution between 2006 and 2016 were retrospectively analysed. Patients with iPCa at definitive pathological examinations were stratified in two groups, according to the preservation of the neurovascular bundles (nerve sparing vs no nerve sparing). Significant PCa was defined as any Gleason score ≥ 3 + 4. Biochemical recurrence (BR) was defined as a sustained PSA level > 0.2 ng/mL on two or more consecutive appraisals. BR rate was assessed only in patients with incidental prostate cancer and at least 2 years of follow-up. Differences in categorical and continuous variables were analysed using the chi-squared test and the Mann-Withney U test, respectively. Biochemical recurrence curves were generated using the Kaplan-Meier method and compared with the Log-rank test. RESULTS: Overall, 343 male patients underwent RARC for bladder cancer within the study period. Nerve-sparing surgery was performed in 143 patients (41%), of these 110 had at least 2 years of follow up after surgery. Patients who underwent nerve-sparing surgery were significantly younger (p < 0.001). Clinically significant PCa was found in 24% of patients. No significant differences regarding preoperative PSA value (p = 0.3), PCa pathological stage (p = 0.5), Gleason score (p = 0.3) and positive surgical margin rates (p = 0.3) were found between the two groups. After a median follow-up of 51 months only one patient, in the no-nerve-sparing group had developed a biochemical recurrence (p = 0.4). CONCLUSIONS: In our series most of the iPca detected in RC specimens can be considered as insignificant with a low rate of BR (0.9%). Nerve-sparing RARC is a safe procedure which did not affect oncological outcomes of patients with iPCa.

Percutaneous tumor ablation versus partial nephrectomy for small renal mass: the impact of histologic variant and tumor size.

BACKGROUND: The aim, of this study was to investigate recurrence rates in patients with T1 renal cell carcinoma (RCC) undergone partial nephrectomy (PN), radiofrequency ablation (RFA) or cryoablation (Cryo). METHODS: We retrospectively evaluated data from 665 (81.4%), 68 (8.3%) and 83 (10.3%) patients who underwent PN, RFA and Cryo, respectively. Kaplan-Meier curves depict recurrence-free survival (RFS) rates in the overall population and after stratifying according to tumor's histology (namely, clear cell RCC and non-clear RCC) and size (namely <2 cm and 2-4 cm). Multivariable Cox regression model was used to identify predictors of recurrence. Cumulative-incidence plots evaluated disease recurrence and other causes of mortality (OCM). RESULTS: Patients referred to PN experienced higher RFS rate compared to those treated with RFA and Cryo at 60-month in the overall population (96.4% vs. 79.4% vs. 87.8%), in patients with clear cell RCC (93.3% vs. 75% vs. 80.4%) and in those with tumor of 2-4 cm (97.3% vs. 78% and 84.4%; all P≤0.01). In patients with non-clear cell RCC and with tumor <2cm, PN showed higher RFS rate at 60-month as compared to RFA (97.9% vs. 84.4% and 95.1% vs. 78.1%, respectively: all P≤0.02). At multi-variate analysis, ablative techniques (RFA [HR=4.03] and Cryo [HR=3.86]) were independent predictors of recurrence (all P<0.03). At competing risks analysis, recurrence rate and OCM were 7.3% and 1.3% vs. 25% and 7.2% vs. 19.9% and 19.9% for PN, RFA and Cryo, respectively. CONCLUSIONS: PN and Cryo showed similar RFS rates in patients with non-clear cell RCC and with renal mass <2cm.

Postoperative outcomes of Fast-Track-enhanced recovery protocol in open radical cystectomy: comparison with standard management in a high-volume center and Trifecta proposal.

BACKGROUND: We aimed at comparing perioperative outcomes in patients submitted to radical cystectomy followed by Fast Track (FT) protocol or standard management, and propose a definition of Trifecta, to improve standardized quality assessment for RC. METHODS: We considered 191 patients submitted to RC between January 2017 and January 2019. Patients followed FT or standard management according to surgeon's preference. Preoperative and intraoperative characteristics, alongside with postoperative outcomes were compared between the two groups. Trifecta was defined as follows: in-hospital stay (HS) ≤ 10 days, time to defecation (TtD) below the overall mean and no major (≥ Clavien-Dindo grade III) complications. Finally, Trifecta achievement rates were assessed in both groups. RESULTS: Seventy-five patients (39%) followed the FT protocol and 116 (61%) standard management. The two groups were homogeneous for preoperative, intraoperative and pathological characteristics. Patients in the FT group had shorter TtD (5 vs. 6 days P=0.006), HS (12 vs. 14 days P=0.008) and lower readmission rate (8% vs. 19% P=0.04). Early complication rates and grades were similar, while less late complications were found in FT group (6.7% vs. 21.6% P=0.006). Trifecta achievement rate was higher for FT group (31% vs. 8% P<0.001). Single-item failure percentages for HS, TtD and major grade complications were respectively 90%, 60% and 19%, with no difference between the two groups. CONCLUSIONS: FT protocol can safely consent faster bowel recovery and earlier discharge after RC, plus reducing readmission rates. Using a Trifecta incorporating essential perioperative outcomes, could improve standardized quality assessment for RC.

Holmium laser prostatectomy in a tertiary Italian center: A prospective cost analysis in comparison with bipolar TURP and open prostatectomy.

OBJECTIVE: To assess the economic impact of Holmium laser enucleation of prostate (HoLEP) in comparison with transurethral resection of prostate (TURP) and open prostatectomy (OP). METHODS: Between January 2017 and January 2018, we prospectively enrolled 151 men who underwent HoLEP, TURP or OP at tertiary Italian center, due to bladder outflow obstruction symptoms. Patients with prostate volume ≤ 70 cc and those with prostate volume > 70 cc were scheduled for TURP or HoLEP and OP or HoLEP, respectively. Intraoperative and early post-operative functional outcomes were recorded up to 6 months follow up. Cost analysis was carried out considering direct costs (operating room [OR] utilization costs, nurse, surgeons and anesthesiologists' costs, OR disposable products costs and OR products sterilization costs), indirect costs (hospital stay costs and diagnostics costs) and global costs as sum of both direct and indirect plus general costs related to hospitalization. Cost analysis was performed comparing patients referred to TURP and HoLEP with prostate volume ≤ 70 cc and men underwent OP and HoLEP with prostate volume > 70 cc respectively. RESULTS: Overall, 53 (35.1%), 51 (33.7%) and 47 (31.1%) were scheduled to HoLEP, TURP and OP, respectively. Both TURP, HoLEP and OP proved to effectively improve urinary symptoms related to BPE. Considering patients with prostate volume ≤ 70 cc, median global cost of HoLEP was similar to median global cost of TURP (2151.69 € vs. 2185.61 €, respectively; p = 0.61). Considering patients with prostate volume > 70 cc, median global cost of HoLEP was found to be significantly lower than median global cost of OP (2174.15 € vs. 4064.97 €, respectively; p ≤ 0.001). CONCLUSIONS: Global costs of HoLEP are comparable to those of TURP, offering a cost saving of only 11.4 € in favor of HoLEP. Conversely, HoLEP proved to be a strong competitor of OP because of significant global cost sparing amounting to 1890.82 € in favor of HoLEP.

The Impact of 3D Digital Reconstruction on the Surgical Planning of Partial Nephrectomy: A Case-control Study. Still Time for a Novel Surgical Trend?

INTRODUCTION: The purpose of this study was to evaluate the impact of 3-dimensional (3D) digital reconstructions of renal models on the arterial clamping approach during partial nephrectomy (PN). PATIENTS AND METHODS: Fifty-seven patients with T1 renal mass, referred for PN, were prospectively enrolled in 2 groups: Group 1 (n = 32) with revision of both 2-dimensional (2D) computed tomography (CT) imaging and 3D virtual model before surgery; Group 2 (n = 25) with revision of 2D CT imaging. Segmentation of the 3D models from preoperative high-quality CT scan was achieved using D2P software. In a sub-analysis of patients treated with PN with the on-clamp approach (n = 36), the effective intraoperative level of arterial clamping was compared with the preoperative planning. RESULTS: In the sub-group of patients referred to PN with the on-clamp approach, the intraoperative selective clamping was performed in 12 (57.1%) patients of Group 1 and in 2 (13.3%) cases of Group 2 (P = .01). The intraoperative management of the renal pedicle was done as preoperatively planned in 61.9% of patients in Group 1 and in 86.6% of cases in Group 2 (P = .1). CONCLUSION: The 3D-guided plan of PN allows to perform selective clamping in higher proportion of patients compared with the standard 2D-guided approach without increasing intraoperative and postoperative complications.

Which patients with clinical localized renal mass would achieve the trifecta after partial nephrectomy? The impact of surgical technique.

How does 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography impact the management of patients with prostate cancer recurrence after surgery?

OBJECTIVE: To evaluate the clinical impact of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography on the planned management of prostate cancer patients with biochemical recurrence after surgery. METHODS: We enrolled 276 prostate cancer patients referred to 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography due to biochemical recurrence after surgery (two consecutive prostate-specific antigen assays ≥0.2 ng/mL). First, the detection rate of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography was assessed according to different prostate-specific antigen levels. Second, the independent predictors of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography positive results were assessed. Finally, the intended treatment before revision of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography was assessed by a multidisciplinary team based on the European Association of Urology guidelines, patient clinical condition and clinical parameters. Then, re-assessment of the treatment plan was prospectively recorded by the same board after revision of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography. The effective clinical impact of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography was rated as major (change in therapeutic approach), minor (same treatment, but modified therapeutic strategy) or none. RESULTS: The overall detection rate of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography was 47.5%. Prostate-specific antigen at 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography (odds ratio 3.52) and prostate-specific antigen doubling time <3 months (odds ratio 3.98) were independent predictors of positive 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography results (all P ≤ 0.03). 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography led to a major treatment change in 177 cases (64.1%), with a minor clinical impact of 2.5%. The overall clinical impact of 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography was 42.4%, 27.7%, 21.2% and 8.7% in men with prostate-specific antigen at 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography of 0.2-0.4, 0.5-1, 1.1-2 and >2 ng/mL, respectively. CONCLUSIONS: 68 Ga-prostate-specific membrane antigen positron emission tomography/computed tomography allows clinicians to radically change the intended treatment approach before imaging evaluation, in roughly two out three individuals.

Clinical evaluation of the iXip index to reduce prostate re-biopsies.

BACKGROUND: Prostate biopsy is the gold standard for prostate cancer (PCa) diagnosis, but it's invasive and associated with adverse events. Novel reliable tumor biomarkers and accurate non-invasive tests are required to avoid biopsies. The immune complex PSA-IgM is a new marker for PCa, and it has been included in an algorithm to generate the diagnostic index iXip, which determines the probability of having PCa. In this study we evaluated the ability of iXip to reduce the number of repeat biopsies in patients with a previous negative biopsy and suspicious for PCa. PATIENTS AND METHODS: 219 patients referred for prostate rebiopsy were included in the study. Each patient underwent a trans-rectal ultrasound-guided prostate biopsy and prostate volume examination. Blood samples were collected before any prostatic manipulation to determine the serological levels of PSA-IgM and PSA. The iXip index was calculated as previously reported using an online calculator. RESULTS: iXip values in patients with a positive biopsy were significantly higher than the ones observed in negative patients (p-value = 0.001). Based on iXip values, patients were divided in five risk groups: those with iXip < 0.2 had 0% probability of having PCa. High values of the Gleason score (≥7) were observed mostly in patients with iXip 0.3-0.8. CONCLUSION: Our preliminary results show that iXip identifies a sub-group of patients who can safely avoid rebiopsy because they do not have PCa. The index is a promising tool that could reduce the number of unnecessary prostate biopsies and the relative clinical complications and expenses.

Italian Prostate Biopsies Group: 2016 Updated Guidelines Insights.

AIM: To present a summary of the updated guidelines of the Italian Prostate Biopsies Group following the best recent evidence of the literature. MATERIALS AND METHODS: A systematic review of the new data emerging from 2012-2015 was performed by a panel of 14 selected Italian experts in urology, pathology and radiology. The experts collected articles published in the English-language literature by performing a search using Medline, EMBASE and the Cochrane Library database. The articles were evaluated using a systematic weighting and grading of the level of the evidence according to the Grading of Recommendations Assessment, Development and Evaluation framework system. RESULTS: An initial prostate biopsy is strongly recommended when i) prostate specific antigen (PSA) >10 ng/ml, ii) digital rectal examination is abnormal, iii) multiparametric magnetic resonance imaging (mpMRI) has a Prostate Imaging Reporting and Data System (PIRADS) ≥4, even if it is not recommended. The use of mpMRI is strongly recommended only in patients with previous negative biopsy. At least 12 cores should be taken in each patient plus targeted (fusion or cognitive) biopsies of suspicious area (at mpMRI or transrectal ultrasound). Saturation biopsies are optional in all settings. The optimal strategy for reducing infection complications is still a controversial topic and the instruments to reduce them are actually weak. The adoption of Gleason grade groups in adjunction to the Gleason score when reporting prostate biopsy results is advisable. CONCLUSION: These updated guidelines and recommendations are intended to assist physicians and patients in the decision-making regarding when and how to perform a prostatic biopsy.

Empiric antibiotics therapy for mildly elevated prostate specific antigen: Helpful to avoid unnecessary biopsies?

PURPOSE: The management of mildly elevated (4.0-10.0 ng/ml) prostate specific antigen (PSA) is uncertain. Immediate prostate biopsy, antibiotic treatment, or monitoring PSA level for 1-3 months is still in controversy. MATERIALS AND METHODS: We retrospectively analysed the effect of empiric antibiotics on an increased PSA in a mono-institutional study. We analysed the data of 100 patients with a PSA of 4-10 ng/ml and normal digital rectal examination undergoing their first prostate biopsy. Patients were divided in two different cohorts. One cohort was submitted to antibiotic therapy (Levoxacin 500 mg daily for 20 days) and both cohort had a re-dosing of PSA before the prostate biopsy. RESULTS: Average age of the whole group of patients was 66.48 ± 8.32 years and their average initial PSA level was 6.67 ± 1.57 ng/mL. In the treated group (N = 49) 29 patients had a decreasing PSA value from mean baseline PSA value of 6.6 ± 1.54 ng/ml to the re-dosed mean PSA level of 5.4 ± 1,61 ng/ml (p = 0.7); 20 patients didn't experience a decrease PSA value, with a mean PSA level of 6.9 ± 1.68 ng/ml. In the control group (N = 51), 30 patients had a decrease of PSA level from mean baseline PSA level of 6.5 ± 1,59 ng/ml to a re-dosed PSA level of 5.5 ± 1.57 ng/ml; 21 patients didn't experience a decrease of PSA value, with a mean PSA level of 6.7 ± 1.71 ng/ml. Multivariate analysis of age, PSA changes, antibiotics therapy and biopsy results (presence or absence of cancer) revealed no significant difference between the two cohorts. Sepsis after biopsy occurred in 3 patient in the antibiotics group (6%) and in one of the control group (2%). CONCLUSIONS: The study, even with some limitations, does not seem to show an advantage due to the administration of antibacterial therapy to reduce PSA values before prostate biopsy and subsequently to reduce unnecessary prostate biopsies.

Laparoscopic radical prostatectomy: 10 years of experience at a single institution.

BACKGROUND/AIM: The Urological Clinic of the S. Orsola-Malpighi University Hospital, Bologna has been carrying out laparoscopic radical prostatectomy since 2002. In this study, we report the results after 10 years of LRP, analyzing in particular the oncological and functional aspects. PATIENTS AND METHODS: Between March 2002 and August 2011, 400 patients underwent laparoscopic radical prostatectomy. Cancer control, recovery of continence and potency were evaluated at 1, 3, 6 and 12 months. All data were retrospectively collected on the basis of thorough clinical and pathological examination. RESULTS: Follow-up ranged from 10 to 122 months. Pathological examination revealed pT2 and pT3 cancers in 63.5% and 36.5% of patients, respectively. The incidence of positive surgical margins and biochemical relapse rate was 33.8% and 12.0%, respectively. CONCLUSION: 10 Years after the first laparoscopic radical prostatectomy was performed at our Center, we can state that it is a reliable alternative to traditional surgery, with satisfactory oncological and functional results.
