Purpose: Prostate cancer (PCa) is the second most common oncologic disease among men. Radical treatment with curative intent provides good oncological results for PCa survivors, although definitive therapy is associated with significant number of serious side-effects. In modern-era of medicine tissue-sparing techniques, such as focal HIFU, have been proposed for PCa patients in order to provide cancer control equivalent to the standard-of-care procedures while reducing morbidities and complications. The aim of this systematic review was to summarise the available evidence about focal HIFU therapy as a primary treatment for localized PCa. Material and methods: We conducted a comprehensive literature review of focal HIFU therapy in the MEDLINE database (PROSPERO: CRD42021235581). Articles published in the English language between 2010 and 2020 with more than 50 patients were included. Results: Clinically significant in-field recurrence and out-of-field progression were detected to 22% and 29% PCa patients, respectively. Higher ISUP grade group, more positive cores at biopsy and bilateral disease were identified as the main risk factors for disease recurrence. The most common strategy for recurrence management was definitive therapy. Six months after focal HIFU therapy 98% of patients were totally continent and 80% of patients retained sufficient erections for sexual intercourse. The majority of complications presented in the early postoperative period and were classified as low-grade. Conclusions: This review highlights that focal HIFU therapy appears to be a safe procedure, while short-term cancer control rate is encouraging. Though, second-line treatment or active surveillance seems to be necessary in a significant number of patients.

Focal instead of whole gland ablation for prostate cancer has been proposed to decrease treatment morbidity. We sought to determine differences in erectile function and urinary continence after focal and whole gland ablation for prostate cancer.From 2009 to 2018, 346 patients underwent high intensity focused ultrasound or cryotherapy for prostate cancer. Urinary continence was defined as use of no pads and sexual potency as enough erection for sexual penetration. Logistic regressions to treatment groups and covariates age, prostate specific antigen, International Society of Urological Pathology grading, prostate volume and energy modality were performed to access the effect of focal therapy in sexual potency and urinary continence after 3 and 12 months. IIEF-5 (International Index of Erectile Function) and I-PSS (International Prostate Symptom Score) questionnaires were evaluated. Propensity score matching was performed to adjust for potential baseline differences between groups.After exclusion, 195 post-focal therapy and 105 post-whole gland therapy patients were included in analysis. No significant difference was seen in baseline I-PSS and IIEF-5 scores. In multivariate models focal therapy was the most important factor related to sexual potency at 3 (OR 7.7) and 12 months (OR 3.9). Median IIEF-5 score at 3 months was 12 and 5 (p0.001), and at 12 months was 13 and 9 (p=0.04) in focal therapy and whole gland therapy groups, respectively. Focal therapy was the only factor related to continence (OR 0.7, p0.001). Results remained significant after propensity score matching.Focal ablation instead of whole gland therapy is the most important factor related to better sexual and urinary continence recovery after high intensity focused ultrasound and cryotherapy for prostate cancer.

Purpose To review the current evidence regarding protocols and outcomes of image-guided focal therapy (FT) for prostate cancer (PCa). Methods A literature search of the latest published studies assessing primary FT for PCa was carried out in Medline and Cochrane library databases followed by a critical review. FT modalities, follow-up strategies, and oncological and toxicity outcomes were summarized and discussed in this review. Results Twenty-four studies with six different sources of energy met the inclusion criteria. A heterogeneity of patient selection, energy sources, treatment templates, and definitions of failure was found among the studies. While a third of patients may be found to have additional cancer burden over 3-5 years following FT, most patients will remain free of a radical procedure. The vast majority of patients maintain urinary continence and good erectile function after FT. Acute urinary retention is the most common complication, whilst severe complications remain rare. Conclusion An increasing number of prospective studies with longer follow-up have been recently published. Acceptable cancer control and low treatment toxicity after FT have been consistently reported. Follow-up imaging and routine biopsy must be encouraged post-FT. While there is no reliable PSA threshold to predict failure after FT, reporting post-FT positive biopsies and retreatment rates appear to be standard when assessing treatment efficacy.

We report oncologic outcomes in patients treated with focal therapy for prostate cancer.We retrospectively analyzed a single institution cohort of men with localized prostate cancer who received focal therapy using high intensity focused ultrasound or cryotherapy from 2009 to 2018. Focal therapy was offered for low or intermediate risk disease (prostate specific antigen less than 20 ng/ml, Gleason score 7 or less and clinical stage T2b or less). Patients with previous prostate cancer treatment or less than 6 months of followup were excluded from study. Failure was defined as local or systemic salvage treatment, a positive biopsy Gleason score of 7 or greater in-field or out-of-field in nontreated patients, prostate cancer metastasis or prostate cancer specific death. Cox regression analysis was done to identify independent predictors of failure after focal therapy.Of the 309 patients included in study 190 and 119 were treated with high intensity focused ultrasound and cryotherapy, respectively. Median followup was 45 months. At 1, 3 and 5 years the failure-free survival rate was 95%, 67% and 54%, and the radical treatment-free survival rate was 99%, 79% and 67%, respectively. The 5-year metastasis-free survival rate was 98% and no prostate cancer specific death was registered in this cohort. Before focal therapy a biopsy Gleason score of 7 (3 + 4) or greater (HR 2.4, p0.001) and nadir prostate specific antigen (HR 2.2, p0.001) were independently associated with failed focal therapy. In the salvage focal therapy setting in-field recurrence after primary focal therapy was associated with poorer failure-free survival (p=0.02).Almost half of the men were free of focal therapy failure 5 years after treatment. Still, a significant proportion experienced recurrence at the midterm followup. The preoperative biopsy Gleason score and nadir prostate specific antigen were significantly associated with treatment failure.

Purpose: To describe the use of endocavitary ultrasound probe as an auxiliary tool when performing partial nephrectomy in cases of endophytic renal tumors, to standardize the method, and to report the preliminary results achieved with this technique. Methods: Fifteen patients diagnosed with completely endophytic underwent partial nephrectomy with the use of an endocavitary ultrasound probe. This article describes the technique involved in partial nephrectomy and details the preparation of the endocavitary ultrasound probe to ensure its safe use. Results: All the patients had a RENAL score between 8 and 11. The median time of warm ischemia was 26 and 18 minutes for laparoscopic or robot-assisted surgery, respectively. The median duration of surgery was 150 minutes, and the median console time was 145 minutes for the laparoscopic and robot-assisted surgery groups, respectively. The median estimate of blood loss was 200 mL. Only three patients in the laparoscopic group had focal positive surgical margins. There were no cases of infection at the site of probe entry. Conclusions: Intraoperative use of an endocavitary ultrasound probe for partial nephrectomy is possible and a safe alternative to the excision of endophytic tumors when neither robotic probes nor laparoscopic probes are available.

INTRODUCTION AND OBJECTIVE:Urinary incontinence(UI) and erectile dysfunction (ED) are common complications of radical prostatectomy(RP) with devastating impact on quality of life(QoL). Baseline cha...

Introduction: The health-related QoL is a patient-centered evaluation covering several aspects. This evaluation seems to be particularly important in patients submitted to radical cystectomy (RC) and urinary diversion with ileal conduit (IC) or a neobladder (NB). Objective: Review all recent data comparing QoL outcomes after radical cystectomy with NB and IC diversions. Evidence Acquisition: A systematic search in PubMed/Medline, Embase, and Cochrane databases was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement in December 2018. All articles published from January 01, 2012 to December 31, 2018, were included. A study was considered relevant if it compared QoL outcomes using validated questionnaires (EORTC QLQ C30, FACT-G, FACT-BL, FACT-VCI, and BCI). Evidence Synthesis: In 11 included studies, a total of 1389 participants were accounted (730 NB and 659 IC cases). The studies were conducted in 8 different countries, two were prospective, and none was randomized. There were two studies favoring results with a neobladder, 3 with incontinent diversion and 6 with no differences. The EORTC-QLQ-C30 was the most used instrument (5 studies) followed by FACT VCI and BCI (3 studies each). Given the heterogeneity of data and lack of prospective studies, a meta-analysis was not performed. Conclusion: No superiority of one urinary diversion was characterized. It seems that the choice must be individualized with an extensive preoperative orientation of the patient and their relatives. That will probably influence how the patient accepts the new condition.

There are few data on the outcomes and toxicity of radical prostatectomy (RP) among men experiencing local recurrence of prostate cancer (PC) following focal therapy (FT). To characterise perioperative, oncological, and functional outcomes after salvage robot-assisted RP (S-RALP) and determine the risk factors for S-RALP failure, we conducted a multicentre cohort study of 82 patients undergoing S-RALP after FT. All had histological confirmation of PC recurrence, with metastatic disease excluded using pelvic magnetic resonance imaging, a bone scan, and/or positron emission tomography/computed tomography. Progression-free survival was 74%, 48%, and 36% at 12, 24, and 36mo after surgery, respectively. The 12-mo continence rate was 83%. There were no intraoperative complications and no major postoperative complications. On multivariable analysis, only infield recurrence (hazard ratio [HR] 3.77, 95% confidence interval [CI] 1.11-12.85; p=0.03) and pT3b stage (HR 5.0, 95% CI 1.53-16.39; p=0.008) were independent predictors of recurrence. This study represents the largest series of salvage surgery after FT and shows that this approach is safe with no increase in toxicity when compared to primary RALP. Men identified as having infield recurrence after FT appear to have phenotypically aggressive disease and should be counselled regarding the potential need for a multimodal therapeutic approach. PATIENT SUMMARY: Robotic surgery after focal therapy for prostate cancer is safe and achieves postoperative continence results similar to those for robotic radical prostatectomy in treatment-naïve patients. However, if the cancer recurrence is within the previously treated field, the oncological prognosis seems to be worse.

Whether focal therapy (FT) jeopardizes subsequent prostate cancer (PCa) salvage treatments, when needed, remains a major concern and is largely unknown. To describe and report safety, oncological and functional outcomes of salvage treatments following PCa recurrence and/or persistence after FT. A systematic review on salvage treatments for PCa recurrence/persistence after FT was carried out according to the PRISMA guidelines using an ‘a priori protocol’. A comprehensive literature review was also performed to investigate options to treat FT PCa recurrence/persistence that have not yet been reported after FT. Four retrospective series were included (n = 67 men); overall quality of the studies was low. Salvage treatments yielded 32.8% (n = 22 of 67) biochemical recurrence rate (BCR) after a 7–62-months mean follow-up. No cancer-related deaths occurred. Patients experienced acceptable complications (n = 12 patients; n = 8 Clavien 3) and rare severe incontinence (4.5% using > 2 pads/day). Erectile function (EF) was rarely assessed (62.8% no information available), being overall poor. Other salvage options have been reported following whole-gland ablation and include: (1) re-do ablation yielding worst BCR and EF but similar complications and continence compared to first line ablation; (2) salvage radiotherapy yielding 16.6–38.8% BCR and acceptable toxicity profile with urinary and EF being poorly assessed. Current evidence is weak and limited to a few retrospective series. Oncological control is acceptable although it seems lower compared to a primary treatment setting. Functional outcomes are comparable to primary treatment with the exception of EF; overall, suggesting FT has little impact on subsequent salvage treatments. Future studies are needed to confirm the current findings.

Aim Achieve an international consensus on how to recover lost training opportunities. The results of this study will help inform future EAES guidelines about the recovery of surgical training before and after the pandemic. Background A global survey conducted by our team demonstrated significant disruption in surgical training during the COVID-19 pandemic. This was wide-spread and affected all healthcare systems (whether insurance based or funded by public funds) in all participating countries. Thematic analysis revealed the factors perceived by trainees as barriers to training and gave birth to four-point framework of recovery. These are recommendations that can be easily achieved in any country, with minimal resources. Their implementation, however, relies heavily on the active participation and leadership by trainers. Based on the results of the global trainee survey, the authors would like to conduct a Delphi-style survey, addressed to trainers on this occasion, to establish a pragmatic step-by-step approach to improve training during and after the pandemic. Methods This will be a mixed qualitative and quantitative study. Semi-structured interviews will be performed with laparoscopic trainers. These will be transcribed and thematic analysis will be applied. A questionnaire will then be proposed; this will be based on both the results of the semi structured interviews and of the global trainee survey. The questionnaire will then be validated by the steering committee of this group (achieve consensus of >80%). After validation, the questionnaire will be disseminated to trainers across the globe. Participants will be asked to consent to participate in further cycles of the Delphi process until more than 80% agreement is achieved. Results This study will result in a pragmatic framework for continuation of surgical training during and after the pandemic (with special focus on minimally invasive surgery training).

We assessed whether prostate cancer (PCa) location might affect oncologic outcomes after focal therapy (FT) for PCa.We identified 274 men receiving FT for PCa using either high intensity focused ultrasound (HIFU) or cryotherapy at a high volume center between 2009 and 2018. Survival analyses using Kaplan-Meier method were used to assess any additional treatment and radical treatment rates according to PCa location. Propensity-score match analysis was used to compare oncologic outcomes of HIFU vs cryotherapy according to PCa location. Covariates were prostate specific antigen, clinical stage, prostate volume, Gleason score, maximum cancer core length, percentage of positive cores and treatment modality.A total of 166 and 108 men received FT with HIFU and cryotherapy, respectively. Overall, 39% (106) and 31% (85) received at least an additional treatment and a radical treatment after FT, respectively, with a median followup of 51 months. At 36 months' followup, the rates of any additional treatment-free survival were 71%, 75%, and 69% for patients with basal, mid-prostate and apical disease, respectively (p=0.7). At multivariable logistic regression analysis, PCa location was not significantly associated with higher risk of either any additional treatment or radical treatment (all p0.4). After matching, there was no difference between HIFU vs cryotherapy in terms of any additional treatment rates according to PCa location.The PCa location does not significantly affect the rate of failure after FT. The presence of an apical lesion should not be considered an exclusion criteria for FT. Both HIFU and cryotherapy likely achieve similar medium-term oncologic results regardless of PCa location.

For a long time, the treatment options for localized prostate cancer (PCa) were active treatment, radical prostatectomy (RP) or radiotherapy (RT), which have excellent oncologic outcomes, however, associated to considerable complications rates, especially erectile dysfunction (ED) and urinary incontinence (UI), worsening quality of life (QoL). This chapter examines salvage therapy after focal therapy.

PURPOSE OF REVIEW: Most of focal therapies has addressed index lesion as the targeted tumour focus to treat localized prostate cancer (PCa), a multifocal disease. The interaction between tumour foci and host cells creates a tumour microenvironment (TME) which affects tumour growth, cellular proliferation, and PCa progression. This review aims to better understand the biology of cancer foci and their interaction with the prostatic microenvironment after focal therapy. RECENT FINDINGS: Index lesions are representative of PCa grade in low-risk patients, but the other foci of tumour, the satellite lesions, gain relevance in higher risk patients. Multiparametric MRI, guided biopsies and new biomarkers in combination are important to address PCa multifocality and to adequately select patients to focal therapy. Stromal, immune, and tumoural components are integrated in tumourigenesis and modified after the inflammation induced by focal therapy. SUMMARY: TME and inflammation play an important role in PCa progression, but further researches are necessary to understand how once protective components of prostate microenvironment become protumour elements and how inflammation induced by focal therapy can affect them. Learning how to modulate TME is an exploratory molecular field that can lead us to better manage PCa in both prevention and treatment scenarios.

We assessed the impact of focal therapy on perioperative, oncologic and functional outcomes in men who underwent salvage robotic assisted radical prostatectomy compared to primary robotic assisted radical prostatectomy.Focal therapy was performed in patients presenting with Gleason score 3 + 3 or 3 + 4, clinical stage cT2a or less, serum prostate specific antigen 15 ng/ml or less, unilateral positive biopsy, maximum length of any positive core less than 10 mm and life expectancy greater than 10 years. Focal therapy was defined as target ablation of the index lesion plus a 1 cm safety margin in the normal ipsilateral prostatic parenchyma. The salvage group included 22 men who underwent salvage prostatectomy after focal therapy failure. The primary group was defined using matched pair 1:2 selection of 44 of 2,750 patients treated with primary prostatectomy. The primary and secondary end points were the between group differences in functional and oncologic outcomes, respectively.Complication rates were comparable (p0.05). Pad-free probability was comparable between the groups at 1 and 2 years (p = 0.8). Recovery of erectile function was significantly lower after salvage robotic assisted radical prostatectomy (p = 0.008), which also showed a significantly lower probability of cumulative biochemical recurrence-free survival compared to primary robotic assisted radical prostatectomy (56.3% vs 92.4% at 2 years, p = 0.001). Salvage prostatectomy demonstrated a significantly increased risk of biochemical recurrence (HR 4.8, 95% CI 1.67-13.76, p = 0.004). Study limitations included the retrospective nature, the lack of randomization and the short followup.Salvage robotic assisted radical prostatectomy after focal therapy failure is feasible with acceptable complication rates. However, patients assigned to primary focal therapy should be advised about a poorer prognosis in terms of oncologic control and lower erectile recovery rates in case of a future salvage surgery.

Objectives: To review the main complications related to the robot-assisted laparoscopic (RAL) approach in urology and to suggest measures to avoid such issues. Methods: A systematic search for articles of the contemporary literature was performed in PubMed database for complications in RAL urological procedures focused on positioning, access, and operative technique considerations. Each complication topic is followed by recommendations about how to avoid it. Results: In all, 40 of 253 articles were included in this analysis. Several complications in RAL procedures can be avoided if the surgical team follows some key steps. Adequate patient positioning must avoid skin, peripheral nerve, and muscles injuries, and ocular and cognitive complications mainly related to steep Trendelenburg positioning in pelvic procedures. Port-site access and closure should not be neglected during minimally invasive procedures as these complications although rare can be troublesome. Technique-related complications depend on surgeon experience and the early learning curve should be monitored. Conclusions: Adequate patient selection, surgical positioning, mentorship training, and avoiding long-lasting procedures are essential to prevent RAL-related complications. The robotic surgical team must be careful and work together to avoid possible complications. This review offers several steps in surgical planning to reach this goal.

Prostate cancer (PCa) is stratified into different risk categories based on the patient's prognosis. High-risk disease was formerly characterized by an increased risk of metastasis and lethality, requiring complex treatments. Surgery was recently highlighted to have a pivotal role for the treatment of such cases, even as monotherapy. In the past, open radical prostatectomy was performed for most patients with high-risk PCa; however, robot-assisted radical prostatectomy (RARP) emerged as a reasonable option because it provided optimal outcomes for low- and intermediate-risk PCa. Robust studies are lacking to properly assess the role of RARP for high-risk PCa. We summarize this knowledge and present a literature review on the perioperative recovery and functional and oncologic outcomes of RARP for the treatment of patients with high-risk PCa.
