Assessing the efficacy of pelvic floor muscle training and duloxetine on urinary continence recovery following radical prostatectomy: A randomized clinical trial.

BACKGROUND: Urinary incontinence (UI) can negatively impact quality of life (QoL) after robot-assisted radical prostatectomy (RARP). Pelvic floor muscle training (PFMT) and duloxetine are used to manage post-RARP UI, but their efficacy remains uncertain. We aimed to investigate the efficacy of PFMT and duloxetine in promoting urinary continence recovery (UCR) after RARP. METHODS: A randomized controlled trial involving patients with urine leakage after RARP from May 2015 to February 2018. Patients were randomized into 1 of 4 arms: (1) PFMT-biofeedback, (2) duloxetine, (3) combined PFMT-biofeedback and duloxetine, (4) control arm. PFMT consisted of pelvic muscle exercises conducted with electromyographic feedback weekly, for 3 months. Oral duloxetine was administered at bedtime for 3 months. The primary outcome was prevalence of continence at 6 months, defined as using ≤1 security pad. Urinary symptoms and QoL were assessed by using a visual analogue scale, and validated questionnaires. RESULTS: From the 240 patients included in the trial, 89% of patients completed 1 year of follow-up. Treatment compliance was observed in 88% (92/105) of patients receiving duloxetine, and in 97% (104/107) of patients scheduled to PFMT-biofeedback sessions. In the control group 96% of patients had achieved continence at 6 months, compared with 90% (p = 0.3) in the PMFT-biofeedback, 73% (p = 0.008) in the duloxetine, and 69% (p = 0.003) in the combined treatment arm. At 6 months, QoL was classified as uncomfortable or worse in 17% of patients in the control group, compared with 44% (p = 0.01), 45% (p = 0.008), and 34% (p = 0.07), respectively. Complete preservation of neurovascular bundles (NVB) (OR: 2.95; p = 0.048) was the only perioperative intervention found to improve early UCR. CONCLUSIONS: PFMT-biofeedback and duloxetine demonstrated limited impact in improving UCR after RP. Diligent NVB preservation, along with preoperative patient and disease characteristics, are the primary determinants for early UCR.

Association between Lesion Location and Oncologic Outcomes after Focal Therapy for Localized Prostate Cancer Using Either High Intensity Focused Ultrasound or Cryotherapy.

PURPOSE: We assessed whether prostate cancer (PCa) location might affect oncologic outcomes after focal therapy (FT) for PCa. MATERIALS AND METHODS: 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. RESULTS: 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 p >0.4). After matching, there was no difference between HIFU vs cryotherapy in terms of any additional treatment rates according to PCa location. CONCLUSIONS: 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.

Optimal Surgical Outcome of Minimally Invasive Partial Nephrectomy (MIPN) Based on an Early Postoperative Estimated Glomerular Filtration Rate (eGFR).

PURPOSE OF REVIEW: To compare laparoscopic partial nephrectomy (LPN) and robot-assisted partial nephrectomy (RAPN) performed in two European tertiary centers using the classic optimal surgical definition - "MIC" - and a new optimal surgical definition: the "Novel TRIFECTA" (NT) concept. We sought to strengthen the PN evidence and to test the NT's performance. RECENT FINDINGS: The study population comprehended 505 cases of localized kidney cancer from two tertiary centers between 2012 and 2019. The NT achievement was higher in the RAPN group when compared to LPN (70.5 vs. 87.4%; p = 0.004), while no differences were found when considering the MIC criteria. Also, a similar high-grade complications rate (Clavien-Dindo > III) and operative time (105 min vs. 100 min; p = NS) were found. In the multivariable regression, the RAPN approach was a predictor of NT achievement (OR 2.45; p = 0.008). NT achievement was higher in the RAPN group, while similar results were found when evaluating the MIC criteria. The NT definition could be more sensitive to the individual-specific responses related to the PN.

Focal Therapy for Localized Prostate Cancer with Either High Intensity Focused Ultrasound or Cryoablation: A Single Institution Experience.

PURPOSE: We report oncologic outcomes in patients treated with focal therapy for prostate cancer. MATERIALS AND METHODS: 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. RESULTS: 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, p <0.001) and nadir prostate specific antigen (HR 2.2, p <0.001) 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). CONCLUSIONS: 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.

Comparison of Initial Experience with Transrectal Magnetic Resonance Imaging Cognitive Guided Micro-Ultrasound Biopsies versus Established Transperineal Robotic Ultrasound Magnetic Resonance Imaging Fusion Biopsies for Prostate Cancer.

PURPOSE: We compared cancer detection rates in patients who underwent magnetic resonance imaging cognitive guided micro-ultrasound biopsy vs robotic ultrasound magnetic resonance imaging fusion biopsy for prostate cancer. MATERIALS AND METHODS: Among 269 targeted biopsy procedures 222 men underwent robotic ultrasound magnetic resonance imaging fusion biopsy and 47 micro-ultrasound biopsy. Robotic ultrasound magnetic resonance imaging fusion biopsy was performed using the transperineal Artemis™ device while micro-ultrasound biopsy was performed transrectally with the high resolution ExactVu™ system. Random biopsies were performed in addition to targeted biopsy in both modalities. Prostate cancer detection rates and concordance between random and target biopsies were also assessed. RESULTS: Groups were comparable in terms of age, prostate specific antigen, prostate volume and magnetic resonance PI-RADS (Prostate Imaging Reporting and Data System) version 2 score. The micro-ultrasound biopsy group presented fewer biopsied cores in random and target approaches. In targeted biopsies micro-ultrasound biopsy cases presented higher detection of clinically significant disease (Gleason score greater than 6) than the robotic ultrasound magnetic resonance imaging fusion biopsy group (38% vs 23%, p=0.02). When considering prostate cancer detection regardless of Gleason score or prostate cancer detection by random+target biopsies, no difference was found between the groups. However, on a per core basis overall prostate cancer detection rates favored micro-ultrasound biopsy in random and targeted scenarios. In addition, the PRI-MUS (Prostate Risk Identification Using Micro-Ultrasound) score yielded by micro-ultrasound visualization was independently associated with improved cancer detection rates of clinically significant prostate cancer. CONCLUSIONS: In our initial experience micro-ultrasound biopsy featured a higher clinically significant prostate cancer detection rate in target cores than robotic ultrasound magnetic resonance imaging fusion biopsy, which was associated with target features in micro-ultrasound (PRI-MUS score). These findings reinforce the role of micro-ultrasound technology in targeted biopsies.

Long-term functional and oncological outcomes of nerve-sparing and prostate capsule-sparing cystectomy: a single-centre experience.

OBJECTIVES: To evaluate the technical feasibility, oncological and functional outcomes of nerve sparing cystoprostatectomy (NSCP) and prostate capsule-sparing cystectomy (PCSC) for the treatment of organ-confined bladder cancer at a single referral centre. PATIENTS AND METHODS: From April 2001 to June 2012, 60 patients underwent PCSC and 47 were treated with NSCP. Inclusion criteria for PCSC were: fully informed consent for the well-motivated patient; negative transurethral resection of the bladder neck; normal prostatic specific antigen (PSA) level (defined as <4 ng/dL during the first year of the study, which was later lowered to 2.5 ng/dL); and normal transrectal ultrasonography, with biopsy for any suspicious nodule. Patients received a complete oncological and functional follow-up. The Kaplan-Meier method was used to depict survival outcomes after surgery. RESULTS: After a median follow-up of 73 and 62 months for PCSC and NSCP, respectively, the 5-year cancer-specific survival was 90% for the PCSC group and 78% for the NSCP group (P = 0.055). Considering complications within 30 days after surgery, 13% and 21% patients had Clavien ≥III complications in the PCSC and NSCP groups, respectively (P = 0.2). For functional outcomes, at 3 months after surgery, 54 (90%) and 24 (51%) patients reported full recovery of daytime urinary continence in the PCSC and NSCP groups, respectively (P < 0.001); and for erectile function recovery, 32 (53%) and four (9%) patients in the PCSC group and in the NSCP group were respectively potent without any treatment (P < 0.001). CONCLUSIONS: NSCP and PCSC are appropriate for a subset of patients with bladder cancer, with excellent oncological and functional results. These surgical procedures should be proposed to well-motivated patients.

Does mpMRI guidance improve HIFU partial gland ablation compared to conventional ultrasound guidance? Early functional outcomes and complications from a single center.

BACKGROUND: Focal therapy (FT) for localized prostate cancer (PCa) treatment is raising interest. New technological mpMRI-US guided FT devices have never been compared with the previous generation of ultrasound-only guided devices. MATERIALS AND METHODS: We retrospectively analyzed prospectively recorded data of men undergoing FT for localized low- or intermediate-risk PCa with US- (Ablatherm®-2009 to 2014) or mpMRI-US (Focal One®-from 2014) guided HIFU. Follow-up visits and data were collected using internationally validated questionnaires at 1, 2, 3, 6 and 12 months. RESULTS: We included n=88 US-guided FT HIFU and n=52 mpMRI-US guided FT HIFU respectively. No major baseline differences were present except higher rates of Gleason 3+4 for the mpMRI-US group. No major differences were present in hospital stay (p=0.1), catheterization time (p=0.5) and complications (p=0.2) although these tended to be lower in the mpMRI-US group (6.8% versus 13.2% US FT group). At 3 months mpMRI-US guided HIFU had significantly lower urine leak (5.1% vs. 15.9%, p=0.04) and a lower drop in IIEF scores (2 vs. 4.2, p=0.07). Of those undergoing 12-months control biopsy in the mpMRI-US-guided HIFU group, 26% had residual cancer in the treated lobe. CONCLUSION: HIFU FT guided by MRI-US fusion may allow improved functional outcomes and fewer complications compared to US- guided HIFU FT alone. Further analysis is needed to confirm benefits of mpMRI implementation at a longer follow-up and on a larger cohort of patients.

Switch from abiraterone plus prednisone to abiraterone plus dexamethasone at asymptomatic PSA progression in patients with metastatic castration-resistant prostate cancer.

OBJECTIVE: To evaluate the effects of switching from prednisone (P) to dexamethasone (D) at asymptomatic prostate-specific antigen (PSA) progression in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone acetate (AA). MATERIALS AND METHODS: Among 93 patients treated with AA between January 2013 and April 2016 in our institution, 48 consecutive asymptomatic patients with mCRPC, who experienced biochemical progression on treatment with AA+P 10 mg/day, were included. A corticosteroid switch to AA+D 0.5 mg/day at PSA increase was administered until radiological and/or clinical progression. The primary endpoint was progression-free-survival (PFS). A prognostic score based on independent prognostic factors was defined. RESULTS: The median time to PSA progression on AA+P was 8.94 months. The median PFS on AA+D and AA+corticosteroids (P then D) was 10.35 and 20.07 months, respectively. A total of 56.25% of patients showed a decrease or stabilization in PSA levels after the switch. In univariate analysis, three markers of switch efficiency were significantly associated with a longer PFS: long hormone-sensitivity duration (≥5 years; median PFS 16.62 vs 4.17 months, hazard ratio [HR] 0.30, 90% confidence interval [CI] 0.16-0.56); low PSA level at the time of switch (<50 ng/mL; median PFS 15.21 vs 3.86 months, HR 0.33, 90% CI 0.18-0.60); and short time to PSA progression on AA+P (<6 months; median PFS 28.02 vs 6.65 months, HR 0.41 (90% CI 0.21-0.81). In multivariate analysis, hormone sensitivity duration and PSA level were independent prognostic factors. CONCLUSION: A steroid switch from P to D appears to be a safe and non-expensive way of obtaining long-term responses to AA in selected patients with mCRPC. A longer PFS has been observed in patients with previous long hormone sensitivity duration, and/or low PSA level and/or short time to PSA progression on AA+P.

Evolution from laparoscopic to robotic nephron sparing surgery: a high-volume laparoscopic center experience on achieving 'trifecta' outcomes.

OBJECTIVE: To evaluate the transition from laparoscopic (LPN) to robotic partial nephrectomy (RPN) in our institution using 'trifecta' outcomes as surrogate marker of efficacy. PATIENTS AND METHODS: We identified 347 patients (LPN = 303, RPN = 44) in our prospectively maintained PN database between 2000 and 2014. The patients were chronologically divided into G1-first 151 LPN cases, G2-subsequent 152 LPN cases and G3-all RPN patients. Trifecta outcomes were defined as warm ischemia time (WIT) ≤25 min, no positive surgical margin (PSM) and complications ≤Clavien 2. Multivariable logistic model was used to analyze the predictors of the trifecta outcomes. RESULTS: The tumor complexity significantly increased from G1 to G3. We achieved lower WIT and less high-grade complication (Clavien ≥ 3) from G1 to G2, and the trend continued even with transition to RPN. PSM was consistently low throughout the transition. Renal functional outcomes always showed a significant positive trend, and with RPN, we achieved improved recovery of renal function (44 vs 57 vs 82 %, p < 0.05). The overall 'trifecta' rates increased significantly from G1 to G2 and reached 81.8 % in RPN (48 vs 75.6 vs 81 %, p < 0.01). Multivariate analysis has shown that the use of robot has significant effect on achieving overall trifecta. The limitations of the study are being retrospective and non-randomized, and the trifecta definitions were not externally validated. CONCLUSIONS: Our transition to RPN was essentially a continuation of our previous LPN experience as we continue to achieve higher 'trifecta' rates inspite of increasing tumor complexity.

Urinary Symptoms Change and Quality of Life After Robotic Radical Prostatectomy: A Secondary Analysis of a Randomized Controlled Trial.

OBJECTIVE: To present the patient-reported quality of life (QoL) outcomes from a prospective, randomized controlled trial comparing the use of pelvic floor muscle training (PFMT) and duloxetine after robot-assisted radical prostatectomy (RARP). METHODS: We identified 213 men with organ-confined disease having post-RARP urinary incontinence who were randomly assigned to received PFMT, duloxetine, combined PFMT-duloxetine and pelvic floor muscle home exercises. Urinary symptoms burden was measured by marked clinical important difference improvement (MCID) defined by using the International Prostate Symptom Score (IPSS) difference of - 8 points (ΔIPSS ≤-8). QoL was assessed according to Visual Analog Scale (VAS), King's Health Questionnaire (KQH), and International Index of Erectile Function (IIEF-5). Multivariable regression analyses aimed to predict MCID, burden of urinary symptoms (IPSS ≥8), and patients reporting to be satisfied (IPSS QoL ≤2) or comfortable (VAS ≤1) post-RARP. RESULTS: Moderate to severe urinary symptoms decreased from 48% preoperatively to 40%, 34%, and 23% at 3, 6, and 12months post-RARP. After surgery, MCID improvement was observed in 19% of patients, and deterioration in 3.3%. Large prostate was the only factor associated to MCID (OR 1.03 [95%CI 1.01-1.05], P = .005). At 6months, patients reached the same degree of preoperative satisfaction. Neurovascular bundle preservation was the only predictor of being comfortable regarding urinary symptoms postoperatively (OR 12.8 [CI95% 1.47-111.7], P = .02 at 3months) and was also associated to higher median postoperative IIEF-5. CONCLUSION: Despite urinary incontinence following RARP, patients with larger prostates experience a reduction of lower urinary tract symptoms within a year, which subsequently elevates QoL. Furthermore, nerve-sparing surgery augments erectile function and urinary outcomes, shaping postoperative QoL.

Evaluation of erectile function after laparoscopic radical prostatectomy in a single center.

INTRODUCTION: To evaluate erectile function among men who had undergone laparoscopic radical prostatectomy and received postoperative medical therapy for erectile dysfunction. MATERIALS AND METHODS: We performed a prospective study in men who underwent laparoscopic radical prostatectomy between September 2003 and November 2005 at our center and who received penile rehabilitation after surgery. All patients had antegrade interfascial dissection. They received 10 mg tadalafil on the fifth postoperative day and continued to receive it every other day, regardless of erectile function. Intracavernous injection of alprostadil was initiated at 3 or 6 months depending on response to treatment with tadalafil. Follow up evaluations were done at 3, 6, 12, 18 and 24 months. Oncologic and functional outcomes and compliance were assessed. Patients filled in International Index of Erectile Function-5 (IIEF-5) questionnaires. RESULTS: Of 1078 men who underwent laparoscopic radical prostatectomy during this time, 586 patients met inclusion criteria, complied with the study medication, and had complete data for 24 months. The patients had a median preoperative baseline IIEF-5 score of 22. A total of 150 patients (26%) underwent unilateral nerve-sparing surgery, while 436 patients (74%) had bilateral nerve-sparing surgery. At 24 months, 35% of patients who underwent unilateral nerve-sparing surgery and 68% of patients who underwent bilateral nerve-sparing surgery reported having sufficient erectile function for intercourse without using intracavernous injection of alprostadil. At 24 months after surgery, the median IIEF-5 score was 13 (1-25) for the whole cohort, 5 (1-25) for patients who had undergone unilateral nerve-sparing surgery, and 15 (1-25) for patients who had undergone bilateral nerve-sparing surgery. CONCLUSIONS: The findings suggest that adequate patient selection and postoperative medical intervention allows the preservation or recovery of erectile function after laparoscopic radical prostatectomy. Inaccurate selection of patients and postoperative assessment might explain inferior erectile function results following this surgery.

Long-term Outcomes of Focal Cryotherapy for Low- to Intermediate-risk Prostate Cancer: Results and Matched Pair Analysis with Active Surveillance.

BACKGROUND: To date, only one trial compared focal therapy and active surveillance (AS) for low-risk prostate cancer (PCa). In addition, long-term outcomes of focal cryotherapy (FC) are lacking. OBJECTIVE: Our aim was to evaluate long-term outcomes of FC and compare them with AS. DESIGN, SETTING, AND PARTICIPANTS: We included two prospective series of 121 (FC) and 459 (AS) consecutive patients (2008-2018) for low- to intermediate-risk PCa. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Study outcomes were radical therapy-free or androgen deprivation therapy (ADT)-free, any treatment-free, metastasis-free, and overall survival. A matched pair analysis was performed using seven covariates. RESULTS AND LIMITATIONS: The median FC follow-up was 85 mo (interquartile range 58-104); 92 (76%) men had International Society of Urological Pathology (ISUP) grade 1. Among matched variables, no significant differences were present except for cT stage and year of entry (both p < 0.01). Ten-year radical therapy-free or ADT-free, any treatment-free, metastasis-free, and overall survival were 51%, 40.2%, 93.9%, and 97%, respectively for FC. No differences were noted with AS (all p > 0.05), with the exception of time to radical therapy, time to radical therapy and ADT, and time to any treatment, all being shorter for AS (all p < 0.01). Freedom from radical treatment or ADT was higher for FC (AS 10 yr 39.3%; p = 0.04). Complications were relatively rare (26.5%) and mainly of low grade (Clavien >2, n = 3); three men developed incontinence (p = 0.0814), while both International Index of Erectile Function 5 and International Prostate Symptom Score scores increased (p = 0.0287 and p = 0.0165, respectively). Limitations include absence of randomization. CONCLUSIONS: At an early long-term follow-up, FC in the context of mainly low-risk PCa is safe and increases time to radical therapy but does not provide meaningful oncological advantages compared with AS. PATIENT SUMMARY: We compared focal cryotherapy with active surveillance mainly for low-risk prostate cancer. Focal cryotherapy, despite having fewer complications, did not yield meaningful advantages over active surveillance at 10 yr. Active surveillance should be preferred to focal cryotherapy for these patients.

Focal High-Intensity Focused Ultrasound vs. Active Surveillance for ISUP Grade 1 Prostate Cancer: Medium-Term Results of a Matched-Pair Comparison.

INTRODUCTION/BACKGROUND: Only 1 randomized controlled trial has compared focal therapy and active surveillance (AS) for the low-risk prostate cancer (PCa). We investigated whether focal HIFU (fHIFU) yields oncologic advantages over AS for low-risk PCa. MATERIALS AND METHODS: We included 2 non-randomized prospective series of 132 (fHIFU) and 421 (AS) consecutive patients diagnosed with ISUP 1 PCa between 2008 and 2018. A matched pair analysis was performed to decrease potential bias. Study main outcomes were freedom from radical treatment (RT) or androgen-deprivation therapy (ADT), treatment-free survival (TFS), time to metastasis, and overall survival (OS). RESULTS: Median fHIFU follow-up was 50 months (interquartile range, 29-84 months). Among matched variables, no major differences were recorded except for AS having more suspicious digital rectal examination findings (P = .0074) and recent enrollment year (P = .0005). Five-year intervention-free survival from RT or ADT was higher for the fHIFU cohort (67.4% vs. 53.8%; P = .0158). Time to treatment was approximately 10 months shorter for AS than for fHIFU (time to RT, P = .0363; time to RT or ADT, P = .0156; time to any treatment, P = .0319). No differences were found in any-TFS (fHIFU, 61.4% vs. AS, 53.8%; P = .2635), OS (fHIFU, 97% vs. AS, 97%; P = .9237), or metastasis (n = 0 in fHIFU and n = 2 in AS; P = .4981). Major complications (≥ Clavien 3) were rare (n = 4), although 36.4% of men experienced complications. No relevant changes were noted in continence (P = .3949). CONCLUSION: At a 4-year median follow-up, fHIFU for mainly low-risk PCa (ISUP grade 1) is safe, may decrease the need for radical treatment or ADT and may allow longer time to treatment compared to AS. Nonetheless, no advantages are seen in PCa progression and/or death (OS).

Focal Brachytherapy for Localized Prostate Cancer: Midterm Outcomes.

PURPOSE: Focal brachytherapy (F-BT) is a suitable technique for focal therapy in localized prostate cancer. It has the ability to adapt the seed implantation to the volume and location of the tumor. The aim of this study was to assess F-BT oncologic, functional, and toxicity midterm outcomes in men who underwent prostate cancer treatment. METHODS AND MATERIALS: The study included 39 men with low- to intermediate-risk prostate cancer treated with F-BT between 2010 and 2015. The dose prescription was 145 Gy. Failure was defined as the presence of any residual prostate cancer in the treated area. The primary and secondary endpoints were the F-BT oncologic and functional outcomes, respectively. A 2-sided P value < .05 indicated statistical significance. RESULTS: The mean follow-up time was 65 months (range, 43-104 months). After 24 months, 34 patients underwent control biopsies and 5 patients refused. The biopsies were negative in 27 cases (79%) and positive in 7 cases (21%), all outside the volume treated. Biochemical relapse-free survival at 5 years, disease-free survival, and overall survival were 96.8% ± 0.032%, 79.5% ± 0.076%, and 100%, respectively. The mean International Prostate Symptom Score at 2 months was significantly higher than initially (P = .0003), with no significant difference later. No late urinary, sexual, or rectal toxicity was observed. Salvage treatment was possible with good tolerance at 3.4 years of follow-up. Limitations of this study include the retrospective nature and lack of randomization. CONCLUSIONS: F-BT is a safe and effective treatment for selected patients presenting with low- or intermediate-risk localized prostate cancer.

Laparoscopic radical prostatectomy is feasible and effective in 'fit' senior men with localized prostate cancer.

OBJECTIVE To assess the effect of age and comorbidity on short-term complications, long-term continence and oncological outcome after laparoscopic radical prostatectomy (LRP) for localized prostate cancer. PATIENTS AND METHODS In all, 2048 consecutive men underwent LRP for localized prostate cancer in one institution. Comorbidity was assessed using the Charlson index. Short-term postoperative complications, transfusion rate, duration of hospital stay, long-term continence and oncological outcome were analysed by age and comorbidity classes. RESULTS Of the 2048 men, 297 were aged ≥ 70 years and 281 had a Charlson index of >0 (mainly diabetes 31%, chronic pulmonary disease 26%, prior other nonmetastatic cancer 16%, prior myocardial infarction 12%). Compared with younger men, senior men had significantly higher pathological stages and tumor grades. Of those 297 men aged ≥ 70 years, 90 (30.3%) developed biochemical relapse, none died from prostate cancer and five (1.7%) died from another cause over a median follow-up of 5 years. The occurrence and severity of short-term postoperative complications were more strongly related to comorbidity than chronological age. Multivariate analysis with stepwise regression confirmed that most important predictors of short-term postoperative complications were a Charlson index of ≥ 2, prostate weight of >80 g, obesity and age of ≥ 70 years. Postoperative continence significantly declined with age (ranging from 87% in men aged <60 years to 67.5% in men aged ≥ 70 years). Predictors of long-term incontinence were age of ≥ 70 years, obesity and need for perioperative transfusion. CONCLUSIONS LRP is feasible and effective in fit senior men (aged ≥ 70 years) with localized prostate cancer, including those at high risk of dying from it.

Higher nodal yield with robot-assisted pelvic lymph node dissection for bladder cancer compared to laparoscopic dissection: implications for more accurate staging.

OBJECTIVES: To compare the lymph node (LN) yield and adequacy of laparoscopic pelvic lymph node dissection (L-PLND) and robot-assisted PLND (R-PLND), as PLND is a fundamental component of radical cystectomy (RC) for bladder cancer (BCa), where a positive status is the most powerful predictor of disease recurrence and survival. PATENTS AND METHODS: We retrospectively reviewed patients undergoing RC with PLND for BCa from January 2007 to July 2019 and grouped them in to L- and R-PLND. Until 2011, patients underwent a standard PLND (S-PLND) with the cranial limit as bifurcation of common iliac artery. Since 2012, an extended PLND (E-PLND) up to aortic bifurcation has been performed. An adequate S- and E-PLND were defined as those that yielded at least 10 and 16 LNs, respectively. The groups were compared for LN yield and adequacy of PLND. RESULTS: During the study period, 305 patients underwent minimally invasive RC in our centre, of which 274 (89.8%) underwent a concomitant PLND (98 L-PLND, 176 R-PLND). R-PLND resulted in a significantly greater median LN yield compared to L-PLND, both in the S-PLND (16 vs 11, P < 0.001) and the E-PLND (19 vs 14, P < 0.001) eras. Also, a significantly higher proportion of patients in the R-PLND group had an adequate PLND compared to the L-PLND group. Surgical approach to PLND (R- vs L-PLND) was the only variable that was significantly associated with an adequate PLND on both univariable (odds ratio [OR] 1.860, 95% confidence interval [CI] 1.114-3.105; P = 0.01) and multivariable (OR 2.109, 95% CI 1.222-3.641; P = 0.007) analyses. CONCLUSION: R-PLND leads to a higher LN yield and a greater probability of an adequate PLND compared to L-PLND for both standard and extended templates. Therefore, the robot-assisted approach would lead to more accurate staging following RC with PLND.

The Role of Percentage of Prostate-specific Antigen Reduction After Focal Therapy Using High-intensity Focused Ultrasound for Primary Localised Prostate Cancer. Results from a Large Multi-institutional Series.

Focal therapy (FT) for prostate cancer (PCa) is emerging as a novel therapeutic approach for patients with low- to intermediate-risk disease, in order to provide acceptable oncological control, whilst avoiding the side effects of radical treatment. Evidence regarding the ideal follow-up strategy and the significance of prostate-specific antigen (PSA) kinetics after treatment is needed. In this study, we aimed to assess the value of the percentage of PSA reduction (%PSA reduction) after FT in predicting the likelihood of any additional treatment or any radical treatment. We retrospectively analysed a multicentre cohort of 703 men receiving FT for low- and intermediate-risk PCa. Overall, the rates of any additional treatment and any radical treatment were 30% and 13%, respectively. The median follow-up period was 41 mo. The median %PSA reduction after FT was 73%. At Cox multivariable analysis, %PSA reduction was an independent predictor of any additional treatment (hazard ratio [HR]: 0.96; p < 0.001) and radical treatment (HR: 0.97; p < 0.001) after FT. For %PSA reduction of>90%, the probability of any additional treatment within 5 yr was 20%. Conversely, for %PSA reduction of <10%, the probability of receiving any additional treatment within 5 yr was roughly 70%. This study is the first to assess the role of %PSA reduction in the largest multicentre cohort of men receiving FT for PCa. Given the lack of standardised follow-up strategies in the FT field, the use of the %PSA reduction should be considered. PATIENT SUMMARY: The percentage of prostate-specific antigen reduction is a useful tool to assess men following focal therapy (FT). It can assist the urologist in setting up an appropriate follow-up and during post-FT patient counselling.
