A consistent rate of patients who are classified as “node-negative” after radical prostatectomy and pelvic lymph-node dissection (PLND) experience a nodal disease relapse. Routine pathological examination can miss micro-metastatic tumor foci in the lymph nodes (LN) of patients with prostate cancer (PCa), resulting in confused tumor staging and clinical decision-making. The aim of the present perspective study was to evaluate the impact of micro-metastasis assessed by serial section (SS), immunohistochemistry (IHC) and real time-Polymerase Chain Reaction (RT-PCR) in patient submitted to radical prostatectomy with extended PLND.

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.

BACKGROUND: We report long-term oncologic outcomes in patients with positive surgical margins (PSMs) at radical prostatectomy (RP) and the oncologic impact of different scenarios of PSMs presentation. METHODS: We selected 494 men with at least 3 years follow-up after surgery. PSMs patterns were recorded as: burden (focal vs multifocal), site (apical-anterior vs posterolateral vs base-bladder neck vs multiple) and side (unilateral vs bilateral). Kaplan-Meier curves depicted the clinical recurrence-free survival (CR-FS) rates at 10-year in the overall population, after biochemical recurrence and according to different PSMs patterns. Multivariate Cox-regression analysis was performed to predict CR. RESULTS: Overall, PSMs sites were apical-anterior, postero-lateral, base-bladder neck and multiple in 19.8%, 23.7%, 3.4% and 43.8%, respectively. Out of 494 patients, 278 (56.3%) had a focal margin, while 216 (43.7%) had a multifocal margin. In 268 (54.3%) and 87 (17.6%) men, PSMs were unilateral and bilateral, respectively. Median follow-up was 93 months. No significant differences were found in CR-FS rates after stratifying according to burden and site of PSMs. Men with unilateral PSMs experienced significant higher CR-FS rates compared to those with bilateral PSMs (87.1% vs. 71,3% at 10 years, p

Purpose To evaluate the accuracy of 11C-choline positron emission tomography (PET)/computed tomography (CT) for nodal staging of prostate cancer (PCa) in different populations of high-risk patients. Patients and Methods We evaluated 262 individuals with intermediate- or high-risk PCa submitted to radical prostatectomy and extended pelvic lymph node dissection. Within men with high-risk disease, we identified a subgroup of individuals harboring very high-risk (VHR, n = 28) disease: clinical stage ≥ T2c and more than 5 cores with Gleason score 8-10; primary biopsy Gleason score of 5; 3 high-risk features; or prostate-specific antigen ≥ 30 ng/mL. The diagnostic accuracy of PET/CT and contrast-enhanced CT (CECT) was assessed after stratifying patients according to risk group classification on a patient- and anatomic region–based analysis. Results On patient-based analysis, considering high-risk patients (n = 155), 11C-choline PET/CT versus CECT had sensitivity and specificity of 50% and 76% versus 21% and 92%, respectively. Considering VHR men as separate subgroups (n = 28), 11C-choline PET/CT versus CECT had sensitivity and specificity of 71% and 93% versus 25% and 79%, respectively. Accordingly, in the VHR category, the area under the curve of 11C-choline PET/CT versus CECT was 0.86 (95% confidence interval, 0.71-1.0) versus 0.69 (95% confidence interval, 0.52-0.86), respectively. On anatomic region–based analysis, considering the VHR group, 11C-choline PET/CT versus CECT had sensitivity and specificity of 70.6% and 95.5% versus 35.3% and 98.5%, respectively. Conclusion Patients with VHR characteristics could represent the ideal candidate to undergo disease staging with PET/CT before surgery with the highest cost efficacy.

Aim: The success of Robot Assisted Laparoscopic Prostatectomy (RALP) is mainly due to his relatively short learning curve. Twenty cases are needed to reach a “4 hours-proficiency”. However, to achieve optimal functional outcomes such as urinary continence and potency recovery may require more experience. We aim to report the perioperative and early functional outcomes of patients undergoing RALP, after a structured modular training program. Methods: A surgeon with no previous laparoscopic or robotic experience attained a 3 month modular training including: a) e-learning; b) assistance and training to the operating table; c) dry console training; d) step by step in vivo modular training performing 40 surgical steps in increasing difficulty, under the supervision of an experienced mentor. Demographics, intraoperative and postoperative functional outcomes were recorded after his first 120 procedures, considering four groups of 30 cases. Results: All procedures were completed successfully without conversion to open approach. Overall 19 (15%) post operative complications were observed and 84% were graded as minor (Clavien I-II). Overall operative time and console time gradually decreased during the learning curve, with statistical significance in favour of Group 4. The overall continence rate at 1 and 3 months was 74% and 87% respectively with a significant improvement in continence rate throughout the four groups (p = 0.04). Considering those patients submitted to nerve-sparing procedure we found a significant increase in potency recovery over the four groups (p = 0.04) with the higher potency recovery rate up to 80% in the last 30 cases. Conclusions: Optimal perioperative and functional outcomes have been attained since early phase of the learning curve after an intensive structured modular training and less than 100 consecutive procedures seem needed in order to achieve optimal urinary continence and erectile function recovery.

Introduction We investigated the diagnostic performance of in-bore endorectal magnetic resonance imaging-guided biopsy (MRI-GB) with a 1.5-T MRI scanner using a 32-channel coil in patients with suspected prostate cancer (PCa). Patients and Methods Seventy patients with ≥ 1 suspicious area found on the preliminary multiparametric MRI scan were enrolled. The index lesion was defined as the lesion with the greatest Prostate Imaging Reporting and Data System, version 2 (PIRADS-v2), score. MRI-GBs were performed with a nonmagnetic biopsy device, needle guide, and titanium double-shoot biopsy gun with dedicated software for needle tracking. Clinically significant PCa was defined as the presence of Gleason score ≥ 7 in the biopsy specimen. Results Seventy index lesions were scheduled for MRI-GB. The median PIRADS-v2 score and the median number of cores per patient was 4 of 5 (interquartile range, 3-5) and 2 (interquartile range, 1-3), respectively. The PCa detection rate was 45.7%. Of the 70 patients, 24 (75%) had clinically significant PCa, with a significant correlation between the PIRADS-v2 score and the Gleason score in the MRI-GB cores ( r = 0.839; 95% confidence interval, 0.535-0.951; P = .003). According to the PIRADs-v2 scheme, the proportion of PCa in the central and anterior regions of the gland was greater in the entire population and in the subgroup of patients with a history of negative transrectal ultrasound-guided biopsy findings ( P ≤ .01 for all). On multivariate analysis, a PIRADS-v2 score of 5 of 5 correlated significantly with the likelihood of PCa at biopsy (hazard ratio, 4.69; 95% confidence interval, 0.92-23.74; P = .04). No major complications were recorded. Conclusion MRI-GB has a high detection rate for PCa, especially for lesions located in the central and anterior regions of the prostate.

BACKGROUND: To assess whether the addition of clinical Gleason score (Gs) 3+4 to the Prostate Cancer Research International: Active Surveillance (PRIAS) criteria affects pathologic results in patients who are potentially suitable for active surveillance (AS) and to identify possible clinical predictors of unfavourable outcome. METHODS: Three hundred and twenty-nine men who underwent radical prostatectomy with complete clinical and follow-up data and who would have fulfilled the inclusion criteria of the PRIAS protocol at the time of biopsy except for the addition of biopsy Gs=3+4 and with at least 10 cores taken have been evaluated. One experienced genitourinary pathologist selected those with real Gs=3+3 and 3+4 in only one core according to the 2005 International Society of Urological Pathology criteria. The primary end point was the proportion of unfavourable outcome (nonorgan confined disease or Gs⩾4+3). Logistic regressions explored the association between preoperative characteristics and the primary end point. RESULTS: Two hundred and four patients were evaluated and 46 (22.5%) patients harboured unfavourable disease at final pathology. After a median follow-up of 73.5 months, there was no cancer-specific death, and 4 (2.0%) patients had biochemical relapse. There were no significant differences in terms of high Gs, locally advanced disease, unfavourable disease and biochemical relapse-free survival among patients with clinical Gs=3+3 vs Gs=3+4. At multivariable analysis, the presence of atypical small acinar proliferation (ASAP) and lower number of core taken were independently associated with a higher risk of unfavourable disease. CONCLUSION: The inclusion of Gs=3+4 in patients suitable to AS does not enhance the risk of unfavourable disease after radical prostatectomy. Additional factors such as number of cores taken and the presence of ASAP should be considered in patients suitable for AS

BACKGROUND: We aimed to determine the prognostic role of tumor size in patients with stage pT3a renal cell carcinoma (RCC). PATIENTS AND METHODS: We analyzed our database of patients who underwent radical nephrectomy for RCC between July 2000 and December 2013. Clinical and pathologic data were obtained for each patient. Patients with stage pT3a disease were divided into 2 subgroups according to the most informative threshold for pathologic tumor dimension that was able to predict survival outcomes (group 1, ≤ 8 cm; group 2, > 8 cm). RESULTS: Globally, 185 consecutive patients were evaluated. The median (interquartile range [IQR]) follow-up was 32 months (18-62 months). The median (IQR) pathologic tumor size was 7.5 cm (5.7-10 cm). Seventy (34.3%) patients died of RCC during the follow-up period. Patients in group 2 experienced worse cancer-specific survival (CSS) rates compared with those in group 1, (5- and 10- year CSS, 52% and 40% vs. 67% and 63%, respectively; P = .001). Overall survival (OS) rates were significantly lower for patients included in group 2 compared with patients in group 1 (5- and 10- year OS rates, 46% and 38% vs. 60% and 57%, respectively; P = .01). Subgroup stratification (hazard ratio [HR], 3.65; P < .001), presence of positive surgical margins (HR, 3.86; P = .22), high Fuhrman grade (HR, 4.33; P < .001), and the presence of sarcomatoid cells (HR, 2.61; P = .02) were found to be independent predictors of CSS. CONCLUSION: Worse oncologic outcomes are observed in patients with stage pT3a RCC tumors > 8 cm. The current TNM classification still does not precisely correlate with CSS. Tumor size should be taken into account in a future revision of the TNM staging system.

INTRODUCTION: Radical orchiectomy (RO) is still considered the standard of care for malignant germ cell tumors, which represent the vast majority of the palpable testicular masses. In those patients diagnosed with small testicular masses (STMs), testis-sparing surgery (TSS) could be an alternative treatment to RO. The aim of this updated review is to evaluate the current indications for TSS, and discuss the oncological and functional results of patients who had undergone organ-sparing surgery for STMs. EVIDENCE ACQUISITION: A non-systematic review of the Literature using the Medline database has been performed, including a free-text protocol using the terms «testis sparing surgery», «testicular sparing surgery», «partial orchiectomy», «testis tumor», «sex cord tumor», and «testis function». Other significant studies cited in the reference lists of the selected papers were also evaluated. EVIDENCE SYNTHESIS: No randomized controlled trials comparing TSS with radical orchiectomy have been reported yet. In those patients with normal contra-lateral testis, the use of TSS is still controversial. In selected cases of gonadal masses

Background The purpose of the study was to evaluate the relationships between the patients' clinical characteristics and the growth pattern of SRMs, and to investigate the predictive factors of tumor growth rates in patients initially managed with AS. Materials and Methods We retrospectively reviewed data from our prospectively collected database of 70 patients diagnosed with 72 SRMs between 1996 and 2013. Clinical and demographic data, and linear and volumetric growth rates were recorded for each patient. A Pearson correlation test was used to evaluate initial tumor size and linear or volumetric growth rate. Logistic regression models were used to evaluate the predictive factors affecting tumor growth kinetics. Results The mean age was 76 ± 6.8 years, and 47 (67.1%) of patients were male. The mean (± SD) and the median (interquartile range [IQR]) tumor size at presentation were 2.1 ± 1.3 and 2.7 (1.8-3.7) cm, respectively. The mean (± SD) and the median (IQR) linear growth rate were 0.5 ± 0.3 and 0.6 (0.4-1.5) cm per year, respectively. Patients treated with delayed surgery experienced a significantly greater mean linear growth rate (1.4 vs. 0.3 cm per year) than those observed in the AS group (P
