RESUMEN
INTRODUCTION: Partial gland ablation (PGA) using high intensity focal ultrasound (HIFU) is an alternative to active surveillance for low to intermediate risk localized prostate cancer. This pilot study assessed quality of life (QoL) outcomes during the implementation of PGA-HIFU at our institution. MATERIALS AND METHODS: We prospectively enrolled 25 men with a diagnosis of localized low/intermediate risk prostate cancer who elected to undergo PGA-HIFU in a pilot study at our institution between 2013 and 2016. Patients underwent pre-treatment mpMRI and transrectal ultrasound-guided biopsies. The primary endpoints were impact on patient-reported functional outcomes (erectile, urinary function, QoL) assessed at 1, 3, 6- and 12-months. RESULTS: The median age was 64 years old (IQR 59.5-67). Baseline median International Index of Erectile Function-15 score was 50, which decreased to 18 at 1 month (p < 0.0005), returned to baseline by 3 months and thereafter. International Prostate Symptom Score median at baseline was 8, which worsened to 12 at 1 month (p = 0.0088), and subsequently improved to baseline thereafter. On the UCLA-Expanded Prostate Cancer Index Composite urinary function, there was a decrease in median score from 92.7 at baseline to 76.0 at 1 month (p < 0.0001), which improved to or above baseline afterwards. QoL remained similar to baseline at each follow up period as assessed by EQ-5D and the Functional Cancer Therapy-Prostate score. CONCLUSIONS: In this initial cohort of PGA-HIFU men at our institution, patients demonstrated a slight, but transient, deterioration in urinary and erectile function at 1 month prior to normalization. All QoL metrics showed no impact upon 1 year of follow up post-treatment.

PURPOSE: To compare biochemical recurrence, sexual potency and urinary continence outcomes of ablative therapy and radical treatment (radical prostatectomy or radiotherapy with androgen deprivation therapy). MATERIAL AND METHODS: A systematic review and meta-analysis followed the PRISMA guidelines were performed. We searched MEDLINE/PubMed. Biochemical recurrence at three and five years; incontinence rate (patients who used one pad or more) and erectile dysfunction rate at 12 and 36 months (patients who did not have sufficient erection to achieve sexual intercourse) were evaluated. The Mantel-Haenszel method was applied to estimate the pooled risk difference (RD) in the individual studies for categorical variables. All results were presented as 95% confidence intervals (95%CI). Random effects models were used regardless of the level of heterogeneity (I²). (PROSPERO CRD42022296998). RESULTS: Eight studies comprising 2,677 men with prostate cancer were included. There was no difference in biochemical recurrence between ablative and radical treatments. We observed the same biochemical recurrence between ablative therapy and radical treatment within five years (19.3% vs. 16.8%, respectively; RD 0.07; 95%CI=-0.05, 0.19; I2=68.2%; P=0.08) and continence rate at 12 months (9.2% vs. 31.8%, respectively; RD -0.13; 95%CI, -0.27, 0.01; I2=89%; P=0.32). When focal treatment was analyzed alone, two studies with 582 patients found higher erectile function at 12 months in the ablative therapy group than in the radical treatment (88.9% vs. 30.8%, respectively; RD -0.45; 95%CI -0.84, -0.05; I2=93%; P=0.03). CONCLUSION: Biochemical recurrence and urinary continence outcomes of ablative therapy and radical treatment were similar. Ablative therapy appears to have a high rate of sexual potency.

INTRODUCTION: We aimed to compare the detection rate of prostate cancer (PCa) and clinically significant (cs)PCa by magnetic resonance imaging-guided targeted biopsy (MTBx) alone and MTBx plus systematic biopsy (SBx) using an outpatient transperineal (TP) approach under local anesthesia. METHODS: A retrospective study of patients who underwent outpatient TP prostate biopsy under local anesthesia at our tertiary institution between 2019 and 2022 was performed. To compare the proportions of PCa and csPCa in both pathways, McNemar's tests were used. Multivariable logistic regression model was fitted to determine the predictors of csPCa. RESULTS: Of 255 men included, 177 (69%) underwent MTBx alone. MTBx had similar detection rate for PCa (56%) and csPCa (47%) compared to the combination of MTBx and SBx (PCa, 61%; csPCa, 49%; p=0.1 and p=0.3, respectively). MTBx had lower median number of biopsy cores compared to the combination of MTBx and SBx (6 vs. 11, p<0.001). At multivariable logistic regression analysis, age (odds ratio [OR] 1.08 [1.04-1.13], p<0.001), prior negative biopsy (OR 0.19 [0.09-0.44], p<0.001), prostate-specific antigen density cutoff ≥ 0.15 (OR 3.17 [1.67-6.01], p<0.001), and prostate imaging reporting and data system ≥4 (OR 12.2 [4.21-35.6], p<0.001) were independent predictors of csPCa. CONCLUSIONS: MTBx showed similar diagnostic performance to the combination of MTBx and SBx in patients undergoing outpatient TP prostate biopsy. Future studies are needed to evaluate the role of MTBx in avoiding unnecessary biopsies.
RESUMEN
INTRODUCTION: Patients with high-risk prostate cancer (HRPCa) are prone to have worse pathological features, resulting in early biochemical recurrence after radical prostatectomy (RP). There is an urgent need to develop novel treatment strategies for this group of patients to optimize their outcomes. The purpose of this study is to perform a systematic review of the role of neoadjuvant hormonal therapy (NHT) followed by RP in HRPCa patients. EVIDENCE ACQUISITION: We performed a systematic review of the following databases, MEDLINE (PubMed), EMBASE, Cochrane Library, and clinical Trial.gov; between January 2007 and August 2023, following the PRISMA guidelines. EVIDENCE SYNTHESIS: After screening and deduplication, we included ten studies from an initial pool of 1275. The risk of bias was low in observational studies but ranged from moderate to low in controlled trials. Five studies utilized traditional androgen deprivation treatments (ADT), revealing favorable pathological outcomes but inconsistency in evaluating oncological results. Additionally, four studies focused on RP combined with androgen receptor pathway inhibitors (ARPIs) in the NHT setting, all showing primarily positive pathological outcome, with no clear evidence of an oncological benefit. Limited long-term follow-up data and a shortage of randomized controlled trials were evident among all the studies included in this review, regardless of the type of hormonal treatment used. CONCLUSIONS: Different hormonal treatments, including traditional ADT and ARPIs, yield positive pathology outcomes. Oncological evidence remains limited, echoing older findings predating ARPIs. Definitive conclusions require longer follow-ups and precise patient selection. Currently, insufficient evidence support ARPIs' superiority over conventional therapy before RP.

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.

Despite the progress of anti-cancer treatment, the prognosis of many patients with solid tumors is still dismal. Reliable noninvasive biomarkers are needed to predict patient survival and therapy response. Here, we propose a Humoral Complementomics approach: a work-up of assays to comprehensively evaluate complement proteins, activation fragments, and autoantibodies targeting complement proteins in plasma, which we correlated with the intratumoral complement activation, and/or local production, focusing on localized and metastatic clear cell renal cell carcinoma (ccRCC). In two prospective ccRCC cohorts, plasma C2, C5, Factor D and properdin were elevated compared to healthy controls, reflecting an inflammatory phenotype that correlated with plasma calprotectin levels but did not associate with CRP or with patient prognosis. Conversely, autoantibodies against the complement C3 and the reduced form of FH (a tumor neo-epitope reported in lung cancer) correlated with a favorable outcome. Our findings pointed to a specific group of patients with elevated plasma C4d and C1s-C1INH complexes, indicating the initiation of the classical pathway, along with elevated Ba and Bb, indicating alternative pathway activation. Boostrapped Lasso regularized Cox regression revealed that the most predictive complement biomarkers were elevated plasma C4d and Bb levels at the time of surgery, which correlated with poor prognosis. In conclusion, we propose Humoral Complementomics as an unbiased approach to study the global state of the complement system in any pathological plasma sample and disease context. Its implementation for ccRCC revealed that elevated C4d and Bb in plasma are promising prognostic biomarkers, correlating with shorter progression-free survival.

BACKGROUND AND OBJECTIVE: A meta-analysis of two randomized STAMPEDE platform trials revealed that 3 yr of abiraterone acetate in addition to androgen deprivation therapy and radiation therapy significantly improved metastasis-free and overall survival (OS) in high-risk nonmetastatic prostate cancer (PCa) and should be considered a new standard of care. The aim of our study was to assess long-term cancer-specific survival (CSS) and OS for surgically treated patients with newly diagnosed nonmetastatic node-negative PCa meeting the STAMPEDE criteria for high risk. METHODS: This was a retrospective, multicenter cohort study of patients with European Association of Urology (EAU) high-risk PCa who underwent radical prostatectomy and extended pelvic lymph node dissection. CSS was assessed using cumulative incidence curves and the Kaplan-Meier method was used to evaluate OS. We used a Fine and Gray model to evaluate the prognostic value of STAMPEDE high-risk factors (SHRFs) for CSS, and a Cox proportional-hazards model to assess the association of SHRFs with OS. KEY FINDINGS AND LIMITATIONS: A total of 2994 patients with EAU high-risk PCa were divided into groups with 0, 1, 2, or 3 SHRFs. The 10-yr survival estimates for patients with 0-1 versus 2-3 SHRFs were 95% versus 82% for CSS and 81% versus 64% for OS (both pâ¯<â¯0.0001). In comparison to patients with 0 SHRFs, hazard ratios were 1.2 (pâ¯=â¯0.5), 3.9 (pâ¯<â¯0.0001), and 5.5 (pâ¯<â¯0.0001) for CSS, and 1.1 (pâ¯=â¯0.4), 2.2 (pâ¯<â¯0.0001), and 2.5 (pâ¯=â¯0.0004) for OS for patients with 1, 2, and 3 SHRFs, respectively. CONCLUSIONS AND CLINICAL IMPLICATIONS: Our results confirm that the STAMPEDE high-risk criteria identify a subgroup of patients with highly aggressive PCa features and adverse long-term oncological outcomes. This population is likely to benefit most from aggressive multimodal treatment. Nevertheless, we have shown for the first time that surgery remains a viable treatment option for patients with STAMPEDE high-risk PCa. PATIENT SUMMARY: Prostate cancer that meets the high-risk definitions from the STAMPEDE trial is an aggressive type of cancer. Our results for long-term cancer control outcomes indicate that surgery is a viable option for the subgroup of patients with this type of prostate cancer.
RESUMEN
International Society of Urological Pathology grade group 1 (GG 1) prostate cancer (PCa) is generally considered insignificant, with recent suggestions that it should even be considered as "noncancerous". We evaluated outcomes for patients with GG 1 PCa on biopsy (bGG 1) and high-risk features (prostate-specific antigen [PSA] >20 ng/ml and/or cT3-4 stage) to challenge the hypothesis that every case of bGG 1 PCa has a benign disease course. We used the multi-institutional EMPaCT database, which includes data for 9508 patients with high-risk PCa undergoing surgery. We included patients with bGG 1 PCa (n = 848) in our analysis and divided them into three groups according to PSA >20 ng/ml, cT3-4 stage, or both. The estimated 10-yr cancer-specific survival (CSS) rate was 96% in the overall population, 88% in the group with both PSA >20 ng/ml and cT3-4 stage, 97% in the group with PSA >20 ng/ml alone, and 98% in the group with cT3-4 stage alone. Similar CSS outcomes were found in subgroups with GG 1 PCa on pathology (n = 502) and with GG 1 on biopsy diagnosed after 2005 (n = 253). Study limitations include the lack of magnetic resonance imaging (MRI) staging and MRI-targeted biopsies. In conclusion, patients with GG 1 and either PSA >20 ng/ml or cT3-4 stage have a low risk of dying from their cancer after surgery. However, patients with GG 1 PCa and both PSA >20 ng/ml and cT3-4 stage are at higher risk of cancer-specific mortality and active treatment should be discussed for this subgroup. Patient summary: We assessed outcomes for patients diagnosed with low-grade prostate cancer on biopsy who also had one or two factors associated with high risk disease. Men with both of those risk factors had a higher risk of dying from their prostate cancer. Active treatment should be discussed for this subgroup of patients.
RESUMEN
BACKGROUND AND OBJECTIVE: Magnetic resonance imaging (MRI) can detect recurrences after focal therapy for prostate cancer but there is no robust guidance regarding its use. Our objective was to produce consensus recommendations on MRI acquisition, interpretation, and reporting after focal therapy. METHODS: A systematic review was performed in July 2022 to develop consensus statements. A two-round consensus exercise was then performed, with a consensus meeting in January 2023, during which 329 statements were scored by 23 panellists from Europe and North America spanning urology, radiology, and pathology with experience across eight focal therapy modalities. Using RAND Corporation/University of California-Los Angeles methodology, the Transatlantic Recommendations for Prostate Gland Evaluation with MRI after Focal Therapy (TARGET) were based on consensus for statements scored with agreement or disagreement. KEY FINDINGS AND LIMITATIONS: In total, 73 studies were included in the review. All 20 studies (100%) reporting suspicious imaging features cited focal contrast enhancement as suspicious for cancer recurrence. Of 31 studies reporting MRI assessment criteria, the Prostate Imaging-Reporting and Data System (PI-RADS) score was the scheme used most often (20 studies; 65%), followed by a 5-point Likert score (six studies; 19%). For the consensus exercise, consensus for statements scored with agreement or disagreement increased from 227 of 295 statements (76.9%) in round one to 270 of 329 statements (82.1%) in round two. Key recommendations include performing routine MRI at 12 mo using a multiparametric protocol compliant with PI-RADS version 2.1 standards. PI-RADS category scores for assessing recurrence within the ablation zone should be avoided. An alternative 5-point scoring system is presented that includes a major dynamic contrast enhancement (DCE) sequence and joint minor diffusion-weighted imaging and T2-weighted sequences. For the DCE sequence, focal nodular strong early enhancement was the most suspicious imaging finding. A structured minimum reporting data set and minimum reporting standards for studies detailing MRI data after focal therapy are presented. CONCLUSIONS AND CLINICAL IMPLICATIONS: The TARGET consensus recommendations may improve MRI acquisition, interpretation, and reporting after focal therapy for prostate cancer and provide minimum standards for study reporting. PATIENT SUMMARY: Magnetic resonance imaging (MRI) scans can detect recurrent of prostate cancer after focal treatments, but there is a lack of guidance on MRI use for this purpose. We report new expert recommendations that may improve practice.

CONTEXT: Despite negative preoperative conventional imaging, up to 10% of patients with prostate cancer (PCa) harbor lymph-node involvement (LNI) at radical prostatectomy (RP). The advent of more accurate imaging modalities such as PET/CT improved the detection of LNI. However, their clinical impact and prognostic value are still unclear. We aimed to investigate the prognostic value of preoperative PET/CT in patients node positive (pN+) at RP. EVIDENCE SYNTHESIS: We retrospectively identified cN0M0 patients at conventional imaging (CT and/or MRI, and bone scan) who had pN+ PCa at RP at 17 referral centers. Patients with cN+ at PSMA/Choline PET/CT but cN0M0 at conventional imaging were also included. Systemic progression/recurrence was the primary outcome; Cox proportional hazards models were used for multivariate analysis. EVIDENCE ACQUISITION: We included 1163 pN+ men out of whom 95 and 100 had preoperative PSMA and/or Choline PET/CT, respectively. ISUP grade ≥4 was detected in 66.6%. Overall, 42% of patients had postoperative PSA persistence (≥0.1 ng/mL). Postoperative management included initial observation (34%), ADT (22.7%) and adjuvant RT+/-ADT (42.8%). Median follow-up was 42 months. Patients with cN+ on PSMA PET/CT had an increased risk of systemic progression (52.9% vs. 13.6% cN0 PSMA PET/CT vs. 21.5% cN0 at conventional imaging; P < .01). This held true at multivariable analysis: (HR 6.184, 95% CI: 3.386-11-295; P < .001) whilst no significant results were highlighted for Choline PET/CT. No significant associations for both PET types were found for local progression, BCR, and overall mortality (all P > .05). Observation as an initial management strategy instead of adjuvant treatments was related with an increased risk of metastases (HR 1.808; 95% CI: 1.069-3.058; P < .05). CONCLUSIONS: PSMA PET/CT cN+ patients with negative conventional imaging have an increased risk of systemic progression after RP compared to their counterparts with cN0M0 disease both at conventional and/or molecular imaging.

ABSTRACT Purpose: To compare biochemical recurrence, sexual potency and urinary continence outcomes of ablative therapy and radical treatment (radical prostatectomy or radiotherapy with androgen deprivation therapy). Material and methods: A systematic review and meta-analysis followed the PRISMA guidelines were performed. We searched MEDLINE/PubMed. Biochemical recurrence at three and five years; incontinence rate (patients who used one pad or more) and erectile dysfunction rate at 12 and 36 months (patients who did not have sufficient erection to achieve sexual intercourse) were evaluated. The Mantel-Haenszel method was applied to estimate the pooled risk difference (RD) in the individual studies for categorical variables. All results were presented as 95% confidence intervals (95%CI). Random effects models were used regardless of the level of heterogeneity (I²). (PROSPERO CRD42022296998). Results: Eight studies comprising 2,677 men with prostate cancer were included. There was no difference in biochemical recurrence between ablative and radical treatments. We observed the same biochemical recurrence between ablative therapy and radical treatment within five years (19.3% vs. 16.8%, respectively; RD 0.07; 95%CI=-0.05, 0.19; I2=68.2%; P=0.08) and continence rate at 12 months (9.2% vs. 31.8%, respectively; RD −0.13; 95%CI, −0.27, 0.01; I2=89%; P=0.32). When focal treatment was analyzed alone, two studies with 582 patients found higher erectile function at 12 months in the ablative therapy group than in the radical treatment (88.9% vs. 30.8%, respectively; RD −0.45; 95%CI −0.84, −0.05; I2=93%; P=0.03). Conclusion: Biochemical recurrence and urinary continence outcomes of ablative therapy and radical treatment were similar. Ablative therapy appears to have a high rate of sexual potency.
RESUMEN
ABSTRACT Introduction: The therapeutic role of pelvic lymph node dissection (PLND) in prostate cancer (PCa) is unknown due to absence of randomized trials. Objective: to present a critical review on the therapeutic benefits of PLND in high risk localized PCa patients. Materials and Methods: A search of the literature on PLND was performed using PubMed, Cochrane, and Medline database. Articles obtained regarding diagnostic imaging and sentinel lymph node dissection, PLND extension, impact of PLND on survival, PLND in node positive "only" disease and PLND surgical risks were critically reviewed. Results: High-risk PCa commonly develops metastases. In these patients, the possibility of presenting lymph node disease is high. Thus, extended PLND during radical prostatectomy may be recommended in selected patients with localized high-risk PCa for both accurate staging and therapeutic intent. Although recent advances in detecting patients with lymph node involvement (LNI) with novel imaging and sentinel node dissection, extended PLND continues to be the most accurate method to stage lymph node disease, which may be related to the number of nodes removed. However, extended PLND increases surgical time, with potential impact on perioperative complications, hospital length of stay, rehospitalization and healthcare costs. Controversy persists on its therapeutic benefit, particularly in patients with high node burden. Conclusion: The impact of PLND on biochemical recurrence and PCa survival is unclear yet. Selection of patients may benefit from extended PLND but the challenge remains to identify them accurately. Only prospective randomized study would answer the precise role of PLND in high-risk pelvis confined PCa patients.

ABSTRACT 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.

ABSTRACT 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.

ABSTRACT Purpose: Propose an approach of prostate cancer (PCa) patients during COVID-19 pandemic. Material and Methods: We conducted a review of current literature related to surgical and clinical management of patients during COVID-19 crisis paying special attention to oncological ones and especially those suffering from PCa. Based on these publications and current urological guidelines, a manual to manage PCa patients is suggested. Results: Patients suffering from cancer are likely to develop serious complications from COVID-19 disease together with an increased risk of postoperative morbidity and mortality. Therefore, the management of oncological patients should be taken into special consideration and most of the treatments postponed. In case the procedure is not deferrable, it should be adapted to the current situation. While the shortest radiotherapy (RT) regimens should be applied, surgical procedures must undergo the following recommendations proposed by main surgical associations. PCa prognosis is generally favourable and therefore one can safely delay most of the biopsies up to 6 months without interfering with survival outcomes in the vast majority of cases. In the same way, most of the localised PCa patients are suitable for active surveillance (AS) or hormonal therapy until local definitive treatment could be reconsidered. In metastatic as well as castration resistant PCa stages, adding androgen receptor targeted agents (abiraterone, apalutamide, darolutamide or enzalutamide) to androgen-deprivation therapy (ADT) could be considered in high risk patients. On the contrary, chemotherapy, immunotherapy and Radium-223 must be avoided with regard to the consequence of hematologic toxicity and risk of COVID-19 infection because of immunodepression. Conclusions: Most of the biopsies should be delayed while AS is advised in those patients with low risk PCa. ADT allows us to defer definitive local treatment in many cases of intermediate and high risk PCa. In regard to metastatic and castration resistant PCa, combination therapies with abiraterone, apalutamide, darolutamide or enzalutamide could be considered. Chemotherapy, Radium-223 and immunotherapy are discouraged.
