Meta-Analysis
OBJECTIVE
The relationship between patient and meningioma characteristics and hormone receptors (HRs) of progesterone, estrogen, and androgen remains poorly defined despite literature suggesting that meningiomas are sensitive to gonadal steroid hormones. Therefore, the authors sought to collect and compare data on this topic by performing a systematic review and meta-analysis of reported studies of HR status in meningiomas.
METHODS
A MEDLINE PubMed literature review conducted for articles published between January 1, 1951, and December 31, 2020, resulted in 634 unduplicated articles concerning meningiomas and HRs. There were 114 articles that met the criteria of detailed detection protocols for progesterone receptor (PR), estrogen receptor (ER), and/or androgen receptor (AR) using immunohistochemistry (IHC) or ligand-binding (LB) assays and simultaneous reporting of HR status with at least one variable among age, sex, histology, location, grade, or recurrence. Between-study heterogeneity and risk of bias were evaluated using graphical and statistical methods. The authors performed a multilevel meta-analysis using random-effects modeling on aggregated data (n = 4447) and individual participant data (n = 1363) with subgroup results summarized as pooled effects. A mixed-effects meta-regression using individual participant data was performed to analyze independently associated variables.
RESULTS
The 114 selected articles included data for 5810 patients with 6092 tumors analyzed to determine the expression of three HRs in human meningiomas: PRs, ARs, and ERs. The proportions of HR+ meningiomas were estimated to be 0.76 (95% CI 0.72-0.80) for PR+ and 0.50 (95% CI 0.33-0.66) for AR+ meningiomas. ER+ meningioma detection varied depending on the measurement method used and was 0.06 (95% CI 0.03-0.10) with IHC and 0.11 (95% CI 0.06-0.20) with LB assays. There were associations between age and PR and ER expression that varied between male and female patients. PR+ and AR+ were more common in female patients (OR 1.84, 95% CI 1.47-2.29 for PR and OR 4.16, 95% CI 1.62-10.68 for AR). Additionally, PR+ meningiomas were enriched in skull base locations (OR 1.89, 95% CI 1.03-3.48) and meningothelial histology (OR 1.86, 95% CI 1.23-2.81). A meta-regression showed that PR+ was independently associated with age (OR 1.11 95% CI 1.09-1.13; p < 0.0001) and WHO grade I tumors (OR 8.09, 95% CI 3.55-18.44; p < 0.0001). ER+ was negatively associated with meningothelial histology (OR 0.94, 95% CI 0.86-0.98; p = 0.044) and positively associated with convexity location (OR 1.12, 95% CI 1.05-1.18; p = 0.0003).
CONCLUSIONS
The association between HRs and meningioma features has been investigated but unexplained for decades. In this study the authors demonstrated that HR status has a strong association with known meningioma features, including WHO grade, age, female sex, histology, and anatomical location. Identifying these independent associations allows for a better understanding of meningioma heterogeneity and provides a foundation for revisiting targeted hormonal therapy in meningioma on the basis of proper patient stratification according to HR status.

[Lu]Lu-PSMA-Radioligand Therapy Efficacy Outcomes in Taxane-Naïve Versus Taxane-Treated Patients with Metastatic Castration-Resistant Prostate Cancer: A Systematic Review and Metaanalysis.
Radioligand therapy (RLT) with Lu-prostate-specific membrane antigen (PSMA) inhibitors ([Lu]Lu-PSMA) is currently approved for patients with metastatic castration-resistant prostate cancer (mCRPC) after progression with at least 1 taxane and 1 androgen-receptor-pathway inhibitor. However, the impact of prior chemotherapy on [Lu]Lu-PSMA-RLT outcomes is debatable, with various studies showing inconsistent results. This study was conducted to precisely evaluate the impact of prior taxane chemotherapy on response and survival outcomes in mCRPC patients after [Lu]Lu-PSMA-RLT. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches in PubMed, Scopus, and Embase were made using relevant key words, and articles up to December 2022 were included. The endpoints included prostate-specific antigen (PSA) response rate (RR), progression-free survival, and overall survival (OS). Individual patient data were pooled when feasible. Univariate odds ratios (ORs) and hazard ratios (HRs) were extracted from the individual articles, and pooled estimates and 95% CIs were generated using metaanalysis. Thirteen articles comprising 2,068 patients were included. In 6 articles (553 patients), taxane-naïve patients had significantly better odds of biochemical response after [Lu]Lu-PSMA-RLT (pooled OR, 1.82; 95% CI, 1.21-2.71). Individual patient data metaanalysis for PSA RRs in 3 articles revealed a significantly higher PSA RR in the taxane-naïve versus taxane-treated patients (57.1% vs. 39.5%; difference, 17.6%; 95% CI, 5.6%-28.9%). Further, taxane-naïve status was also a predictor of significantly better progression-free survival (5 articles; 1,027 patients; pooled HR, 0.60; 95% CI, 0.51-0.69) and OS (8 articles; 1,594 patients; pooled HR, 0.54; 95% CI, 0.43-0.68) after [Lu]Lu-PSMA-RLT. There was no evidence of publication bias. mCRPC patients with no prior taxanes had significantly better outcomes after [Lu]Lu-PSMA-RLT than did taxane-treated patients. Further trials evaluating [Lu]Lu-PSMA-RLT in the taxane-naïve setting are now required.

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.

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
Although selective estrogen receptor modulators have been proposed as a treatment for men with central functional hypogonadism, only a few data have been produced in men with obesity-related functional androgen deficiency.
OBJECTIVE
To determine whether and to what extent selective estrogen receptor modulators are an effective and safe therapy in men with obesity-related functional androgen deficiency.
MATERIALS AND METHODS
A thorough search of PubMed, Web of Science, Scopus, and Cochrane Library databases was performed to identify studies comparing testosterone levels before and after treatment. Mean differences with 95% coefficient intervals were combined using random effects models. Funnel plot, Egger's test, and trim-and-fill analysis were used to assess publication bias.
RESULTS
Seven studies met the inclusion criteria providing information on 292 men with obesity-related functional androgen deficiency treated with clomiphene citrate (12.5-50 mg daily) or enclomiphene citrate (12.5-25 mg daily) for 1.5-4 months. The pooled estimates indicated a significant increase in testosterone levels both with clomiphene (mean difference: 11.56 nmol/L; 95% coefficient interval: 9.68, 13.43; I = 69%, p = 0.01) and enclomiphene citrate (mean difference: 7.50 nmol/L; 95% coefficient interval: 6.52, 8.48; I = 4%, p = 0.37). After the exclusion of one study on severely obese men, who exhibited the highest response rate to clomiphene citrate, the heterogeneity disappeared (mean difference: 10.27 nmol/L; 95% coefficient interval: 9.39, 11.16; I = 0%, p = 0.66). No publication bias was revealed by Egger's test and trim-and-fill analysis. No treatment-related unexpected findings regarding safety profile were registered.
DISCUSSION AND CONCLUSION
Treatment with clomiphene citrate and enclomiphene citrate may be an effective and safe alternative to testosterone replacement therapy in men with obesity-related functional androgen deficiency. Further long-term studies are warranted to define clinical reflections of the selective estrogen receptor modulators-induced increase in testosterone levels and to better clarify the safety profile.
