Cell therapy for male sexual dysfunctions: systematic review and position statements from the European Society for Sexual Medicine.

Background: Cell therapy (CT) is a form of regenerative medicine under investigation for the management of male sexual dysfunction (MSD). Aim: We sought to perform a systematic review of published information on CT for MSD and provide an official position statements for the European Society for Sexual Medicine. Methods: A comprehensive bibliographic search on the MEDLINE, Web of Science, Scopus, and Cochrane Library databases was conducted in February 2023. Articles were selected based on the Population, Intervention, Comparator, Outcome, Study design (PICOS) model if they included male patients (P) undergoing CT (I) with or without comparison with other treatments (C) and evaluated the impact of CT on sexual function (O). Quantitative data were reported as found in the original studies (S). Level of evidence and grade of recommendation according to the Oxford Centre for Evidence-Based Medicine were assigned to each statement. Outcomes: Outcomes were determined based on assessment of erectile function, ejaculatory function, orgasmic function, sexual desire, and penile curvature. Results: A total of 19 studies and 421 patients were included. Most articles (n = 12, 63%) were case series, whereas a minority of papers (n = 6, 32%) had a comparative group; only 2 articles reported randomized controlled trials (RCTs) and 1 article reported a post hoc analysis of RCTs. Most articles (16, 84%) investigated patients with erectile dysfunction (ED). Improvements in the International Index of Erectile Function-Erectile Function Domain (IIEF-EF) or the IIEF 5-item version (IIEF-5) were found in 11/15 (73%) studies, with mean increases in IIEF-EF, mean IIEF-5, and median IIEF-EF between 8 and 14 points, 2 and 9 points, and 4.5 and 6 points, respectively. Two papers (20%) evaluated men with Peyronie's disease (PD). In both ot these articles penile curvature improvement and plaque volume reduction were described in all patients (n = 16, 100%). Objective measurements were performed in 1 study, which showed 10°-120° (15%-100%) curvature improvement and 90%-100% plaque reduction. Mild transient adverse events at the donor or administration sites were found in 7/16 (44%) papers on ED. Priapism was reported in one case (20%) and mild penile skin complications were reported in the majority of patients after CT for PD. No severe adverse events were described. Clinical Implications: Although high-quality evidence is lacking, CT appears to have potential benefits from application in patients with ED or PD. Strengths and Limitations: This report is to our knowledge the most comprehensive and up-to-date systematic review on the topic of CT for the management of MSD, including the position statements of the European Society for Sexual Medicine. Overall the assessment of available studies demonstrated low quality and significant heterogeneity. Conclusion: Preliminary findings support potential efficacy and safety of CT in patients with ED or PD. Low-quality papers, high methodological heterogeneity, uncertainty about the magnitude of the beneficial effects, and lack of long-term data limit the available evidence.

Comparison in Detection Rate of Clinically Significant Prostate Cancer Between Microultrasound-guided Prostate Biopsy (ExactVu) and Multiparametric Resonance Imaging-guided Prostate Biopsy (Koelis System).

OBJECTIVES: To compare the detection rate of clinically significant prostate cancer (csPC) and prostate cancer (PC) and to find out the diagnostic concordance between microultrasound (mUS), a high-resolution imaging system that can identify suspicious prostate lesions and biopsy them in real time, and multiparametric magnetic resonance imaging (mpMRI)-guided prostate fusion biopsies. METHODS: A prospective, multicenter, single-blind, single cohort study was conducted involving 80 patients with clinically suspected PC who underwent concomitant mpMRI-guided fusion prostate biopsy (Koelis System) and mUS-guided biopsy (ExactVu System) RESULTS: The detection rate of csPC was slightly higher for image-guided fusion biopsy (21.25% vs 18.75%), but this difference was not statistically significant (P = .453). There was also no significant difference in overall PC diagnosis (50% vs 51.25%, P = .897). The degree of agreement between the 2 diagnostic techniques for the detection of csPC as assessed by Cohen's Kappa concordance index was satisfactory κ ̂ = 0.676. The degree of International Society of Urological Pathology of targeted biopsies obtained from concordant lesions was also represented by satisfactory concordance with a Kappa index of κ ̂ = 0. 696. CONCLUSION: mUS-guided biopsy is presented as an effective diagnostic method for the diagnosis of csPC compared to image-guided fusion biopsy. No differences are found in the detection rates of csPC and PC between the 2 strategies and satisfactory concordance is found in terms of histopathological findings.

Organ-Sparing Surgery for Testicular Germ Cell Tumors: A Current Perspective.

Background and Objectives: We aimed to evaluate the oncological and functional outcomes of organ-sparing surgery for testicular germ cell tumors, a procedure that seeks to strike a balance between effective cancer control and organ preservation, in the treatment of testicular tumors. We aimed to discuss the surgical technique and complications, and determine the appropriate candidate selection for this approach. Material and Methods: A comprehensive literature search was conducted to identify relevant studies on organ-sparing surgery for testicular tumors. Various databases, including PubMed, Embase, and Cochrane Library, were used. Studies reporting on surgical techniques, complications, and oncologic and functional outcomes were included for analysis. Results: Current evidence suggests that organ-sparing surgery for testicular germ cell tumors can be considered a safe and efficacious alternative to radical orchiectomy. The procedure is associated with adequate oncological control, as indicated by low recurrence rates and low complication rates. Endocrine testicular function can be preserved in around 80-90% of patients and paternity can be achieved in approximately half of the patients. Candidate selection for this surgery is typically based on the following criteria: pre-surgery normal levels of testosterone and luteinizing hormone, synchronous or metachronous bilateral tumors, tumor in a solitary testis, and tumor size less than 50% of the testis. Conclusions: Organ-sparing surgery for testicular germ cell tumors offers a promising approach that balances oncological control and preservation of testicular function. Further research, including large-scale prospective studies and long-term follow-ups, is warranted to validate the effectiveness and durability of organ-sparing surgery and to identify optimal patient selection criteria.

Study UNICO: Perception of Urologists and Andrologists, in Spain, about the Use of Sildenafil Oral Suspension in Patients with Erectile Dysfunction.

OBJECTIVE: To describe the profile of patients with erectile dysfunction (ED), attending to consultation and satisfaction using sildenafil oral suspension, from the specialist's perception. MATERIALS AND METHODS: This is a nationwide multicenter, epidemiological, descriptive and observational study, with the studied population as the unit of study. Thirty urologists and/or andrologists completed a questionnaire with questions about ED patients' profile attending to their practice, sildenafil oral suspension perception of effectiveness and safeness, and their opinion about patients' satisfaction after sildenafil oral suspension treatment. Aggregate data were collected for the last 6 patients treated or on treatment with sildenafil oral suspension. RESULTS: Overall, 40.9% and 24.9% of patients had moderate or severe ED, respectively. Among the patients, 73.6% were older than 50 years. The disease progression was approximately one year (11.8 months). ED etiology was mostly organic (38.1%) and mixed (31.8%). Cardiovascular comorbidities were present in 57.4%, mental health problems in 16.4% and hormonal disorders in 10.2% of the patients. The main reason for choosing sildenafil oral suspension was the ease of dose adjustment. The specialists considered that 73.4% of the patients responded satisfactorily to treatment. They also rated the perceived effectiveness and safeness of the product as very good or good. CONCLUSIONS: Urologists and andrologists consider that most patients with ED achieve a high degree of satisfaction with sildenafil oral suspension. The main advantage of the treatment is the possibility of adjusting the dose according to patient's needs and circumstances.

Conservative Non-surgical Options for Erectile Dysfunction.

PURPOSE OF REVIEW: This study aimed to review recent evidence on conservative non-surgical options for erectile dysfunction (ED) in men. A narrative review of the literature was performed. A comprehensive search in the MEDLINE, Embase, and Cochrane databases was done. Papers in English language, published from May 2017 until May 2022, were included. Papers reporting basic research or animal research were excluded, as long as reviews or meta-analyses. Congress reports, clinical cases, or clinical trials protocols with no results were also excluded. RECENT FINDINGS: We found a multitude of different treatment modalities for ED. We must take into account the type of patient, their comorbidities, the origin of their ED, and its severity in order to reproduce effective results using these therapies. Some of the treatments show good results with a good level of evidence (new IPDE5 formulations, intracavernous injections, shock wave therapy, hormonal theraphy, psycho-sexual theraphy). However, others (some new molecules, stem cell theraphy, platelet-rich plasma injections, oxygenation-based therapy, nutraceuticals), although some of them present promising results, require randomized studies with a larger number of patients and a longer follow-up time to be able to establish firm recommendations. Regarding the conservative treatment of erectile dysfunction, in recent years, some therapies have been consolidated as effective and safe for certain types of patients. On the other hand, other treatment modalities, although promising, still lack the evidence and the necessary follow-up to be recommended in daily practice.

Functional Role of STIM-1 and Orai1 in Human Microvascular Aging.

The impact of aging on vascular function is heterogeneous depending on the vascular territories. Calcium regulation plays a key role in vascular function and has been implicated in aging-related hypercontractility of corpus cavernosum. We aimed to evaluate stromal interaction molecule (STIM)/Orai system involvement in aging-related vascular alterations in the human macro and microvasculature. Aortae specimens and mesenteric arteries (MA), obtained from 45 organ donors, were functionally evaluated in organ chambers and wire myographs. Subjects were divided into groups either younger or older than 65-years old. The expressions of STIM-1, Orai1, and Orai3 were determined by immunofluorescence in the aorta and MA, and by Western blot in the aorta homogenates. The inhibition of STIM/Orai with YM-58483 (20 µM) reversed adrenergic hypercontractility in MA from older subjects but did not modify aging-related hypercontractility in the aortic strips. Aging was related to an increased expression of Orai1 in human aorta, while Orai1 and STIM-1 were upregulated in MA. STIM-1 and Orai1 protein expressions were inversely correlated to endothelial function in MA. Circulating levels of Orai1 were correlated with the inflammatory factor TNF-α and with the endothelial dysfunction marker asymmetric dimethylarginine. Aging is associated with an increased expression of the STIM/Orai system in human vessels with functional relevance only in the microvascular territory, suggesting its role in aging-related microvascular dysfunction.

STIM/Orai Inhibition as a Strategy for Alleviating Diabetic Erectile Dysfunction Through Modulation of Rat and Human Penile Tissue Contractility and in vivo Potentiation of Erectile Responses.

BACKGROUND: Stromal interaction molecule (STIM)/Orai calcium entry system appears to have a role in erectile dysfunction (ED) pathophysiology but its specific contribution to diabetic ED was not elucidated. AIM: To evaluate STIM/Orai inhibition on functional alterations associated with diabetic ED in rat and human penile tissues and on in vivo erectile responses in diabetic rats. METHODS: Rat corpus cavernosum (RCC) strips from nondiabetic (No DM) and streptozotocin-induced diabetic (DM) rats and human penile resistance arteries (HPRA) and corpus cavernosum (HCC) from ED patients undergoing penile prosthesis insertion were functionally evaluated in organ chambers and wire myographs. Erectile function in vivo in rats was assessed by intracavernosal pressure (ICP) responses to cavernous nerve electrical stimulation (CNES). Expression of STIM/Orai elements in HCC was determined by immunofluorescence and immunoblot. MAIN OUTCOME MEASURES: Functional responses in RCC, HCC and HPRA and STIM/Orai protein expression in HCC. In vivo erectile responses to CNES. RESULTS: Inhibition of Orai channels with YM-58483 (20 µM) significantly reduced adrenergic contractions in RCC but more effectively in DM. Thromboxane-induced and neurogenic contractions were reduced by STIM/Orai inhibition while defective endothelial, neurogenic and PDE5 inhibitor-induced relaxations were enhanced by YM-58483 (10 µM) in RCC from DM rats. In vivo, YM-58483 caused erections and attenuated diabetes-related impairment of erectile responses. YM-58483 potentiated the effects of PDE5 inhibition. In human tissues, STIM/Orai inhibition depressed adrenergic and thromboxane-induced contractions in ED patients more effectively in those with type 2 diabetes. Diabetes was associated with increased expression of Orai1 and Orai3 in ED patients. CLINICAL TRANSLATION: Targeting STIM/Orai to alleviate diabetes-related functional alterations of penile vascular tissue could improve erectile function and potentiate therapeutic effects of PDE5 inhibitors in diabetic ED. STRENGTHS AND LIMITATIONS: Improving effects of STIM/Orai inhibition on diabetes-related functional impairment was evidenced in vitro and in vivo in an animal model and validated in human tissues from ED patients. Functional findings were complemented with expression results. Main limitation was low numbers of human experiments due to limited human tissue availability. CONCLUSIONS: STIM/Orai inhibition alleviated alterations of functional responses in vitro and improved erectile responses in vivo in diabetic rats, potentiating the effects of PDE5 inhibition. STIM/Orai inhibition was validated as a target to modulate functional alterations of human penile vascular tissue in diabetic ED where Orai1 and Orai3 channels were upregulated. STIM/Orai inhibition could be a potential therapeutic strategy to overcome poor response to conventional ED therapy in diabetic patients. Sevilleja-Ortiz A, El Assar M, García-Gómez B, et al.

Impact of Surgery for Benign Prostatic Hyperplasia on Sexual Function: A Systematic Review and Meta-analysis of Erectile Function and Ejaculatory Function.

CONTEXT: Several sexual side effects, including erectile, ejaculatory, and orgasmic dysfunction, were reported with the majority of surgical procedures for benign prostatic obstruction (BPO). OBJECTIVE: To systematically review current evidence regarding the impact of benign prostatic hyperplasia (BPH) surgery on sexual function. EVIDENCE ACQUISITION: A comprehensive bibliographic search on the MEDLINE, Cochrane Library, Embase, Web of Science, and Google Scholar databases was conducted in July 2021. The population, intervention, comparator, and outcome (PICO) model was used to define study eligibility. Studies were Included if they assessed patients with BPO and related lower urinary tract symptoms (P) undergoing BPH surgery (I) with or without a comparison between surgical treatments (C) evaluating the impact on sexual function (O). Retrospective and prospective primary studies were included. A pooled analysis was conducted on studies including the postoperative assessment of International Index of Erectile Function (IIEF)-5, Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD; Function and/or Bother), or retrograde ejaculation (RE) rate (PROSPERO database ID: CRD42020177907). EVIDENCE SYNTHESIS: A total of 151 studies investigating 20 531 patients were included. Forty-eight randomized controlled trials evaluating 5045 individuals were eligible for the meta-analysis. In most studies (122, 80.8%), only erectile and/or ejaculatory function was evaluated. A substantial number of articles (67, 44.4%) also used nonvalidated tools to evaluate erectile and/or ejaculatory function. The pooled analysis showed no statistically significant changes in IIEF-5 score compared with baseline for the transurethral resection of the prostate (TURP; weighted mean difference [WMD] 0.76 pts; 95% confidence interval [CI] -0.1, 1.62; p = 0.08), laser procedure (WMD 0.33 pts; 95% CI -0.1, 0.77; p = 0.13), and minimally invasive treatment (WMD -1.37 pts; 95% CI -3.19, 0.44; p = 0.14) groups. A statistically significantly higher rate of RE was found after TURP (risk ratio [RR] 13.31; 95% CI 8.37, 21.17; p < 0.00001), other electrosurgical procedures (RR 34.77; 95% CI 10.58, 127.82; p < 0.00001), and the entire laser group (RR 17.37; 95% CI 5.93, 50.81; p < 0.00001). No statistically significant increase in RE rate was described after most of the minimally invasive procedures (p > 0.05). The pooled analysis of MSHQ-EjD scores was possible only for prostatic urethral lift, showing no statistically significant difference between baseline and post-treatment MSHQ-EjD Function scores (WMD -0.80 pts; 95% CI -2.41, 0.81; p = 0.33), but postoperative MSHQ-EjD Bother scores were significantly higher (WMD 0.76 pts; 95% CI 0.22, 1.30; p = 0.006). CONCLUSIONS: Erectile function appears to be unaffected by most surgical procedures for BPO. RE is a very common adverse event of BPH surgery, although emerging minimally invasive surgical procedures could be associated with a lower risk. PATIENT SUMMARY: Benign prostatic hyperplasia surgery can have an impact on sexual function, mainly involving ejaculatory function.

[Postmortem sperm retrieval: Two cases report and review of technical and legislative aspects in Spain]. / Recuperación espermática post mortem: análisis técnico y legislativo en España a propósito de dos casos.

INTRODUCTION AND OBJECTIVES: Advances in assisted reproductive techniques (ART) have caused an increase in requests for postmortem sperm retrieval (PMER). The use of these techniques is usually tied to legal, ethical and medical/casuistic problems. The objective of this work is to analyze technical and legal aspects of PMER in Spain using two real cases and to establish guidelines to help in decision-making after a PMER request. MATERIAL AND METHODS: Two real cases in which a PMER was requested and others published in Spain in recent years are presented. We proceed to an exposition of the techniques used in postmortem ART cases and specifically in PMER, and a detailed study of the current legal framework is carried out. RESULTS: In Spain we have a complete law on ART. Article 9 expressly requires an authorization from the deceased male partner for the use of his reproductive material in the following 12 months. Regarding the PMER, technical and logistical considerations require a quick and organized decision-making. The time until extraction should not exceed 24-36hours from death and a good choice of biological material is essential. CONCLUSIONS: Medical-scientific advances now allow PMER and the use of postmortem ART. A good knowledge of the technical, logistical and legal aspects is necessary for a fast and coordinated action.

Early manifestation of aging-related vascular dysfunction in human penile vasculature-A potential explanation for the role of erectile dysfunction as a harbinger of systemic vascular disease.

Advanced age is related to functional alterations of human vasculature, but erectile dysfunction precedes systemic manifestations of vascular disease. The current study aimed to simultaneously evaluate the influence of aging on vascular function (relaxation and contraction responses) in systemic human vascular territories: aorta (HA) and resistance mesenteric arteries (HMA) and human corpus cavernosum (HCC) and penile resistance arteries (HPRA). Associations of oxidative stress and inflammation circulating biomarkers with age and functional responses were also determined. Vascular specimens were obtained from 76 organ donors (age range 18-87). Four age-groups were established: < 40, 40-55, 56-65 and > 65 years old. Increasing age was associated with a decline in endothelium-dependent relaxation induced by BK in HMA (r = -0.597, p = 0.0001), or by ACh in HCC (r = -0.505, p = 0.0022), and HPRA (r = -0.601, p = 0.0012). Significant impairment was detected at > 65 years old in HMA but earlier in penile vasculature (> 55 years old). Age-related reduction to H2O2-vasodilatory response started before in HCC (56-65 years old) than in HA (> 65 years old). In contrast to relaxation responses, aging-related hypercontractility to adrenergic stimulation was homogeneous: contractions significantly increased in subjects > 55 years old in all tested vessels. Although not significantly age related, circulating levels of ADMA (r = -0.681, p = 0.0052) and TNF-α (r = -0.537, p = 0.0385) were negatively correlated with endothelial vasodilation in HMA but not in HCC or HPRA. Penile vasculature exhibits an early impairment of endothelium-dependent and H2O2-induced vasodilations when compared to mesenteric microcirculation and aorta. Therefore, functional susceptibility of penile vasculature to the aging process may account for anticipation of erectile dysfunction to systemic manifestations of vascular disease.

Penile length augmentation surgical and non-surgical approaches for aesthetical purposes.

The aim of this review is to describe reported techniques and to provide available scientific data on the success of penis length procedures for cosmetic purposes. Penis lengthening methods remain a controversial issue. Penis size is a matter of great interest among men who are affected by 'small penis anxiety'' or just believe themselves to have a small penis, even though the dimensions of the organ fall within the normal range. We performed a narrative review of the literature based on a comprehensive search in the MEDLINE database for original articles published until March 2021, referring to lengthening approaches exclusively for aesthetical reasons. Abstracts, opinion papers and case series ≤10 patients were not considered. We included the results of 14 papers in the review that gathered the experience obtained in a total of 1661 patients. Four of the studies referred to non-surgical procedures for penile length augmentation (PLA) and the remaining 10 analyzed the results of invasive (surgical) procedures. Both invasive and non-invasive techniques achieve similar improvements in penis length. These procedures vary in complexity and require specialized training and experience. However, the low scientific quality of the analyzed papers makes it difficult to establish recommendations to choose one technique over any other. However, it seems reasonable that, if possible, non-invasive techniques should be proposed as a first-line treatment. Before deciding the procedure, we must carry out a correct psychological evaluation of our patients, discuss with them the technique of choice, and adjust their expectations.

Peyronie's Disease Questionnaire (PDQ): Spanish translation and validation.

The Peyronie's Disease Questionnaire (PDQ) is a 15-question self-reported questionnaire that evaluates the severity and physical and psychosexual issues of Peyronie's disease (PD) symptoms in three scales: "psychological and physical symptoms," "penile pain," and "symptom bother." Previous studies validated the PDQ US version and confirmed its test-retest reliability and responsiveness. The aim is to translate and validate the Spanish version of the PDQ to be used in the clinical practice and in PD research studies in Spain. A non-interventional, observational study with 160 PD patients was conducted. Patients included from four healthcare centers in Spain and completed the PDQ in two study visits separated for a period of 4-7 days from March 2018 to June 2019. Patients received no type of treatment or intervention. Different statistical tests were applied to the data in order to validate the structural and construct of the PDQ, as well as its internal reliability, temporal stability reliability, reliability between observers, and test-retest reliability. Cronbach's alpha over 0.9 showed good internal consistency. We found an ICC agreement of 0.82 (test-retest) for the three scales of the Spanish version of the PDQ, which demonstrates good reliability. When comparing Visit 1 and Visit 2 questionnaires mean scores, the PDQ showed non-significant differences, as expected because no intervention or treatment was administered to the patients between visits. Translation and validation of the PDQ for the Spanish population makes available a valid, useful, and reliable tool to properly evaluate quality of life of men suffering PD.

Ageing-induced hypercontractility is related to functional enhancement of STIM/Orai and upregulation of Orai 3 in rat and human penile tissue.

The role of STIM/Orai calcium entry system on vascular ageing has not been elucidated. We aimed to evaluate the influence of ageing on STIM/Orai signalling and its role on ageing-induced alterations of contractile function in rat corpus cavernosum (RCC) and human penile resistance arteries (HPRA) and corpus cavernosum (HCC). RCC was obtained from 3 months-old and 20 months-old animals. HPRA and HCC were obtained from organ donors of varied ages without history of erectile dysfunction. Aging was associated with enhanced norepinephrine (NE)- and thromboxane analogue (U46619)-induced contractions in RCC which were significantly inhibited by the STIM/Orai inhibitor, YM-58483 (20 µM). Other STIM/Orai inhibitor, 2-aminoethyldiphenylborate also reduced NE-induced contractions in RCC from aged rats. YM-58483 significantly reduced neurogenic contractions and potentiated neurogenic relaxations in RCC from aged rats. In HCC and HPRA, NE-induced contractions were significantly enhanced in older subjects (>65 years-old) but YM-58483 completely reversed ageing-related hypercontractility. Ageing did not modify STIM-1 and Orai1 protein expressions but Orai3 was significantly overexpressed in cavernosal tissue from old rats and older subjects. Contribution of STIM/Orai to cavernosal contraction increases with ageing together with increased expression of Orai3. Orai inhibition could be a potential therapeutic strategy to reduce ageing-related impact on vascular/erectile function.

The Use of Penile Traction Devices for Peyronie's Disease: Position Statements from the European Society for Sexual Medicine.

INTRODUCTION: Penile traction therapy (PTT) aims to non-surgically reduce curvature, enhance girth, and recover lost length. Available clinical practice guidelines however lack clear recommendations regarding their use. AIM: To present a comprehensive review and recommendation regarding the available evidence to the use of PTT in Peyronie's disease (PD). METHODS: A systematic literature search was performed on Pubmed and Medline for relevant studies from all times until 2019. Studies of PTT (monotherapy and in combination) in patients with PD with any documented degree of curvature and in either the acute or chronic phase of the disease were included. Full texts not published in English language were excluded. MAIN OUTCOMES MEASURES: Several scenarios, including preclinical data have been investigated. For each topic covered evidence was analyzed and expert opinion was stated. RESULTS: The paucity of high-level studies precluded any strong recommendations, however, specific statements on this topic, summarizing the ESSM position, were provided. The available data about the use of PTT in PD are still poor, and the impact of this therapy for the treatment of PD has not been clearly stablished. Available data in the clinical setting are still poor, and the impact of these devices on PD evolution has not been clearly established. CONCLUSION: PTT seems to be a valid treatment option for PD, although there is not enough evidence to give any definitive recommendation in any clinical scenario.

Seizures and Neuropsychiatric Toxicity in Patients with Non-Metastatic CRPC Treated with New Antiandrogens: Systematic Review and Meta-Analysis.

INTRODUCTION: Recently, enzalutamide, apalutamide, and darolutamide have shown benefits in metastasis-free survival in non-metastatic castration-resistant prostate cancer (nmCRPC) patients compared to placebo. Previous evidence about the safety profile of these new androgens is limited. This meta-analysis studies seizure and neuropsychiatric effects of new anti-androgens compared to placebo in nmCRPC patients. METHODS: PubMed and Cochrane databases were systematically reviewed until 1 March 2020 by 2 independent researchers using a pre-specified search strategy. Placebo-compared randomized controlled trials (RCTs) of nmCRPC patients treated with new anti-androgens providing data on neuropsychiatric events and seizures were included. Variables were seizure, headache, mental impairment, and dizziness. Pooled risk ratios (RR) were calculated using the Mantel-Hansel random effects model and Review Manager v5.3 software. RESULTS: After systematic review, 3 eligible RCTs were selected that included 4,104 patients; 2,687 comprised the treatment group and 1,417 the control group. No significant increase in RR for seizures was registered with the new anti-androgens compared to placebo (RR 1.96; 95% confidence interval [CI] 0.40-9.61). However, 2 trials excluded patients with risk factors or a history of seizures. There was also no significant increase RR for grade ≥3 seizures (RR 2.50; 95% CI 0.12-52.02). RR for suffering dizziness (any grade) was 1.57 (95% CI 1.07-2.32) with the new anti-androgens, but no significant differences were found in the other study regarding neuropsychiatric events or grade ≥3 events. CONCLUSIONS: New anti-androgens (i.e., enzalutamide, apalutamide, and darolutamide) are acceptably safe in terms of seizures and neuropsychiatric toxicity compared to placebo in patients with nmCRPC.
