Meta-Analysis
Based on ARASENS trial: efficacy and safety of darolutamide as an emerging option of endocrinotherapy for metastatic hormone-sensitive prostate cancer-an updated systematic review and network meta-analysis.
PURPOSE
The newly published ARASENS trial has demonstrated the clinical efficacy of darolutamide for metastatic hormone-sensitive prostate cancer (mHSPC). However, the use of darolutamide as the latest first-line androgen receptor pathway inhibitor for mHSPC has not been compared with other androgen receptor targeted agents (ARTAs). Given the lack of head-to-head randomized trials, we performed this updated meta-analysis to conduct indirect comparison for the efficacy and safety of darolutamide with other new-generation ARTAs.
METHODS
By searching the databases of PubMed, Scopus, Cochrane Library, and Embase, 9 large randomized controlled trials evaluating ARTAs for mHSPC patients were eventually screened according to PRISMA. We extracted data from overall survival, castration-resistant progression, and adverse events for network meta-analysis using the Bayesian and standard frequentist models.
RESULTS
Darolutamide combination emerged with superiority (HR = 0.68, 95%CrI = 0.57-0.81) among four androgen receptor inhibitors for patients with high Gleason score (HR = 0.71, 95%CrI = 0.59-0.86). Darolutamide was best tolerated in several androgen suppression-related adverse events (AEs).
CONCLUSION
Darolutamide appears to be an optional androgen receptor inhibitor for mHSPC patients, especially for patients with Gleason score ≥ 8. Its well-tolerated characteristic may provide a preferred drug option for patients with poor cardiovascular function and bone health.

Meta-Analysis
BACKGROUND
Hormone therapy, which is widely prescribed for prostate cancer, might induce cognitive impairment and affect the autonomy of elderly patients. However, previous studies provided conflicting results. The aim of this systematic review and meta-analysis was to synthesize the longitudinal impact of hormone therapy on objective (cognitive tests) and subjective (questionnaires) cognition.
METHODS
A search was performed of the PubMed, Web of Science, and PsycINFO databases. Studies that longitudinally assessed cognition in patients undergoing androgen-deprivation therapy and new-generation hormone therapy were considered. To perform a meta-analysis, available scores were aggregated and classified into six objective domains and one subjective domain. Weighted mean effect sizes were computed using a random effect model.
RESULTS
Twenty studies were included in the systematic review (1440 patients), and 15 could be included in the meta-analysis (1093 patients). In the systematic review, 20%-50% of patients had objective cognitive impairment before treatment initiation. The meta-analysis revealed a decline in subjective cognition (g = -0.44; p = .03) with androgen-deprivation therapy and new-generation hormone therapy. All other effect sizes were small (from g = -0.02 to g = 0.18), and none of them indicated a significant decline in objective cognition. Significant heterogeneity was observed in all domains of objective cognition.
CONCLUSIONS
This synthesis presents the first meta-analytic evidence of the negative impact of androgen-deprivation therapy and new-generation hormone therapy on subjective cognition. In contrast, there was no conclusive evidence of a decline in objective cognition. The high heterogeneity underscores the need for homogeneous cognitive research on prostate cancer.
PLAIN LANGUAGE SUMMARY
There is no consensus on the cognitive impairment induced by hormone therapy for prostate cancer, despite the implications for patients' care and daily life. This synthesis of published studies demonstrated an increase in perceived cognitive difficulties but did not prove a decline in cognitive performance during treatment.

Meta-Analysis Review
INTRODUCTION
The influence of androgen suppression therapy (AST) on bladder cancer (BCa) remains controversial, as recent studies have not reached a consensus regarding the relationship between AST and the incidence or prognosis of BCa.
MATERIALS AND METHODS
We perform an updated systematic review and meta-analysis utilizing the most recent evidence to investigate the potential influence of AST on the incidence and prognosis of BCa. A comprehensive literature search was performed on the PubMed, Medline, Embase, Web of Science, and the Cochrane Library databases to include potentially eligible studies. Hazard ratios (HR) and odds ratios (OR) were used to calculate the incidence and prognosis of BCa.
RESULTS
This meta-analysis included 22 studies with 700,755 participants which investigated the impact of AST on the risk and prognosis of BCa. The pooled results revealed no significant relation between AST and a decreased incidence of BCa (OR: 0.92, 95%CI: 0.77-1.09, P = 0.342). Subgroup analysis reported that patients receiving 5-alpha reductase inhibitors (5-ARIs) exhibited a significantly lower risk of BCa (OR: 0.83, 95%CI: 0.75-0.91, P < 0.001), while androgen deprivation therapy did not show a significant reduction (OR: 1.00, 95%CI: 0.46-2.16, P = 0.995). AST may also significantly improve the recurrence-free survival of patients with BCa (HR: 0.69, 95%CI: 0.50-0.95, P = 0.023). We also detected a significant improvement in OS among BCa patients who received 5-ARIs compared to those without 5-ARIs (HR: 0.82, 95%CI: 0.68-0.99, P = 0.037).
CONCLUSION
No significant correlation was found between AST and a decreased BCa incidence, while 5-ARIs have demonstrated efficacy in reducing BCa occurrence. Moreover, patients who received AST demonstrated improved prognosis.

Cardiovascular and Thromboembolic Events in Patients With Localized Prostate Cancer Receiving Intensified Neoadjuvant Androgen Deprivation: A Systematic Review and Meta-Analysis.
Several phase II trials have investigated neoadjuvant novel androgen receptor signaling inhibitors (ARSIs) in combination with androgen deprivation therapy (ADT) followed by radical prostatectomy (RP) in prostate cancer (PC) patients. However, data regarding complications of intense hormone therapy and surgical complications are scarce. Our objective was to evaluate the occurrence of cardiovascular (CV) and thromboembolic (TE) adverse events (AE) in patients with localized PC who have received intense neoadjuvant ADT followed by prostatectomy. A comprehensive search in MEDLINE, Embase, Scopus and conference abstracts was performed. The strategies were developed and applied for each electronic database on March 7th, 2023. Eligible studies included randomized and single-arm trials testing ARSIs prior to prostatectomy that adequately reported safety data regarding CV and TE AE, peri-operative complications, and mortality during therapy. Pooled incidence (PI) of AE with 95% confidence interval (95% CI) was estimated using a random effects model. Quality assessment and reporting followed Cochrane Collaboration Handbook and PRISMA guidelines. PROSPERO: CRD42022344104. Nine randomized controlled trials and three single-arm phase II trials were included, comprising 702 patients (702 patients for CV AE and 522 for perioperative complications). The neoadjuvant regimen was classified as monotherapy with ARSI (100 patients), combination therapy with ADT + ARSI (383 patients), or ADT + ARSI + ARSI (219 patients). The PI of TE within the perioperative interval was 4.2% (95% CI = 2.6%-6.6%, I2 = 0.0%, P = .65), and the PI for CV AE was 4.6% (95% CI = 3.1%-6.7%, I2 = 0.0%, P = .71). Seven deaths were reported, resulting in a PI of 2.2% (95% CI = 1.3%-3.8%, I2 = 0.0%, P = .99), of which two were considered treatment-related and occurred within the perioperative period. The PI of hypertension grade 3-5 was 7.3% (95% CI = 4.8%-11.0%, I2 = 38.8%, P = .04). CV and TE AE associated with intense neoadjuvant hormone therapy in patients with localized PC can occur in up to 4.6% of cases. Our data warns for further assessment of thrombotic risk and prophylactic anticoagulation in this setting.

Review
Acne vulgaris, commonly called acne, is a skin condition affecting many individuals globally. It is a chronic condition characterized by developing pimples, blackheads (open comedones), whiteheads (closed comedones), and other skin lesions. Acne usually appears on the face, neck, chest, and back. It is commonly associated with puberty and adolescence but can also affect adults of all ages. Acne can be very frustrating and embarrassing, leading to low self-esteem and social isolation. The condition arises from various factors, including clogged pores, excessive sebum production, bacteria, and inflammation. This systematic review assesses the effectiveness of topical antibiotics, retinoids, niacinamide, azelaic acid, and clascoterone in treating mild-to-moderate acne vulgaris. A comprehensive search across PubMed, PubMed Central, and Google Scholar yielded 10 articles focused on topical antibiotics, with findings from 198 subjects indicating the efficacy of doxycycline against inflammatory lesions. Retinoids, such as tretinoin and adapalene, significantly improved both lesion types (open and closed comedones). Niacinamide, examined in a randomized controlled trial involving 41 participants, reduced sebum production. Another study with 60 patients revealed that azelaic acid effectively reduced both inflammatory and non-inflammatory lesions. Clascoterone emerged as a promising antiandrogenic treatment, supported by a randomized controlled trial involving 4,440 patients. It is essential that individualized therapy, incorporating patient preferences and considering adverse effects, is emphasized for optimizing acne management.

Review
BACKGROUND
In 2019, the breakthrough of the coronavirus 2 disease (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), represented one of the major issues of our recent history. Different drugs have been tested to rapidly find effective anti-viral treatments and, among these, antiandrogens have been suggested to play a role in mediating SARS-CoV-2 infection. Considering the high heterogeneity of studies on this topic, we decided to review the current literature.
METHODS
We performed a systematic review according to PRISMA guidelines. A search strategy was conducted on PUBMED and Medline. Only original articles published from March 2020 to 31 August 2023 investigating the possible protective role of antiandrogens were included. In vitro or preclinical studies and reports not in the English language were excluded. The main objective was to investigate how antiandrogens may interfere with COVID-19 outcomes.
RESULTS
Among 1755 records, we selected 31 studies, the majority of which consisted of retrospective clinical data collections and of randomized clinical trials during the first and second wave of the COVID-19 pandemic.
CONCLUSIONS
In conclusion, we can state that antiandrogens do not seem to protect individuals from SARS-CoV-2 infection and COVID-19 severity and, thus, their use should not be encouraged in this field.

Review
Neuroendocrine prostate cancer (NEPC) is a rare subtype of prostate cancer (PCa) that usually results in poor clinical outcomes and may be accompanied by paraneoplastic syndromes (PNS). NEPC is becoming more frequent. It can initially manifest as PNS, complicating diagnosis. Therefore, we reviewed the literature on the different PNS associated with NEPC. We systematically reviewed English-language articles from January 2017 to September 2023, identifying 17 studies meeting PRISMA guidelines for NEPC and associated PNS. A total of 17 articles were included in the review. Among these, Cushing's Syndrome (CS) due to ectopic Adrenocorticotropic hormone (ACTH) secretion was the most commonly reported PNS. Other PNS included syndrome of inappropriate Anti-Diuretic Hormone secretion (SIADH), Anti-Hu-mediated chronic intestinal pseudo-obstruction (CIPO), limbic encephalitis, Evans Syndrome, hypercalcemia, dermatomyositis, and polycythemia. Many patients had a history of prostate adenocarcinoma treated with androgen deprivation therapy (ADT) before neuroendocrine features developed. The mean age was 65.5 years, with a maximum survival of 9 months post-diagnosis. NEPC is becoming an increasingly more common subtype of PCa that can result in various PNS. This makes the diagnosis and treatment of NEPC challenging. Further research is crucial to understanding these syndromes and developing standardized, targeted treatments to improve patient survival.

Review
The effect of dietary interventions or patterns on the cardiometabolic health of individuals treated with androgen deprivation therapy for prostate cancer: A systematic review.
Prostate cancer survivors treated with androgen deprivation therapy may be at increased risk of cardiovascular disease. Dietary recommendations for the prevention and/or management of cardiovascular disease for these individuals are lacking. This review synthesizes the evidence on the effect of dietary interventions on cardiometabolic biomarkers and cardiovascular disease risk in prostate cancer survivors receiving androgen deprivation therapy. A systematic review was conducted across PubMed, CINAHL, Embase, and Cochrane CENTRAL. Intervention or observational cohort studies evaluating diets, nutrients, or nutraceuticals with or without concurrent exercise interventions on cardiovascular disease, cardiovascular events, or cardiovascular disease biomarkers in those treated with androgen deprivation therapy were included. Confidence in the body of evidence was appraised using Grading of Recommendations, Assessment, Development and Evaluations. Twelve studies reported across fifteen papers were included. Interventions were heterogenous, with most studies including an exercise co-intervention (n = 8). Few significant findings for the effects of diet on cardiometabolic markers were likely due to weak methodology and sample sizes. Strongest evidence was for the effect of a healthy Western dietary pattern with exercise on improved blood pressure (Confidence: moderate). The healthy Western dietary pattern with exercise may improve high-density lipoprotein cholesterol (Confidence: Low) and flow-mediated dilation. Soy may improve total cholesterol (Confidence: Very low). A low-carbohydrate diet with physical activity may improve high-density lipoprotein cholesterol, incidence of metabolic syndrome, and Framingham cardiovascular disease risk score. Evidence of the effect of dietary interventions on cardiometabolic biomarkers and cardiovascular disease risk of prostate cancer survivors receiving androgen deprivation therapy is insufficient to inform practice. Well-designed dietary interventions aimed at improving cardiometabolic outcomes of this population are warranted to inform future dietary recommendations.

Meta-Analysis
PURPOSE
This systematic review and meta-analysis aimed to evaluate the evidence for ultrahypofractionated pelvic nodal irradiation in patients with prostate cancer, with a focus on reported acute and late toxicities.
METHODS AND MATERIALS
A comprehensive search was conducted in 5 electronic databases (PubMed, Scopus, Web of Science, Cochrane Library, ClinicalTrials.gov) from inception until March 23, 2023. Eligible publications included patients with intermediate- and high-risk and node-positive prostate cancer who underwent elective or therapeutic ultrahypofractionated pelvic nodal irradiation. Primary outcomes included the presence of grade ≥2 rates of acute and late gastrointestinal and genitourinary toxicity based on the Common Terminology Criteria for Adverse Events or Radiation Therapy Oncology Group scales. Quality assessment was performed using National Institutes of Health tools for noncontrolled beforeand after (single arm) clinical trials, as well as single-arm observational studies. Because all outcomes were categorical variables, proportion was calculated to estimate the effect size and compare the outcomes after the intervention.
RESULTS
We identified 16 publications that reported the use of ultrahypofractionated radiation therapy to treat the pelvis in prostate cancer. Seven publications met our criteria and were included in the meta-analysis, including 417 patients. The median total dose to the pelvic lymph nodes was 25 Gy (range, 25-28.5 Gy), with a median of 5 fractions. The prostate received a median dose of 40 Gy (range, 35-47.5 Gy). All studies used androgen deprivation therapy for a median duration of 18 months. The median follow-up period was 3 years (range, 0.5-5.6 years). The rates of acute grade ≥2 gastrointestinal and genitourinary toxicity were 8% (95% CI, 1%-15%) and 29% (95% CI, 18%-41%), respectively. For late grade ≥2 gastrointestinal and genitourinary toxicity, the rates were 13% (95% CI, 5%-21%) and 29% (95% CI, 17%-42%), respectively.
CONCLUSIONS
Ultrahypofractionated pelvic nodal irradiation appears to be a safe approach in terms of acute and late genitourinary and gastrointestinal toxicity.

Review
Health-related quality of life in patients with metastatic hormone-sensitive prostate cancer treated with androgen receptor signaling inhibitors: the role of combination treatment therapy.
BACKGROUND
While the addition of androgen receptor signaling inhibitors (ARSIs) to androgen deprivation therapy (ADT) results in better of overall survival in patients with metastatic hormone-sensitive prostate cancer (mHSPC), information regarding health related quality of life (HR-QoL) is sparse. We aimed at summarizing current evidence on the impact of ARSIs on HR-QoL.
METHODS
We performed a systematic review of the published literature on PubMed/EMBASE, Web of Science, SCOPUS, and the Cochrane libraries between January 2011 and April 2022. We included only phase III randomized controlled trials (RCT), which were selected according to the PRISMA guidelines. We aimed at evaluating differences in HR-QoL, assessed by validated patient reported outcomes instruments. We analyzed global scores and sub-domains such as sexual functioning, urinary symptoms, bowel symptoms, pain/fatigue, emotional and social/family wellbeing. We reported data descriptively.
RESULTS
Six RCTs were included: two used enzalutamide with ADT as intervention arms (ARCHES, ENZAMET); one used apalutamide with ADT (TITAN); two abiraterone acetate and prednisone (AAP) with ADT (STAMPEDE, LATITUDE); and one darolutamide with ADT (ARASENS). Enzalutamide or AAP with ADT increase overall HR-QoL in comparison with ADT alone, ADT with first generation nonsteroideal anti-androgens or ADT with docetaxel, whereas apalutamide and darolutamide with ADT maintain HR-QoL similarly to ADT alone or ADT with docetaxel, respectively. Time to first deterioration of pain was longer with combination therapy with enzalutamide, AAP or darolutamide, but not with apalutamide. No worsening of emotional wellbeing was reported from the addition of ARSIs to ADT than ADT alone.
CONCLUSIONS
The addition of ARSIs to ADT in mHSPC tends to increase overall HR-QoL and prolong time to first deterioration of pain/fatigue compared with ADT alone, ADT with first generation nonsteroideal anti-androgens, and ADT with docetaxel. ARSIs show a complex interaction with remaining HR-QoL domains. We advocate a standardization of HR-QoL measurement and reporting to allow further comparisons.
