Meta-Analysis Review
PURPOSE
There are limited pooled data showing the impact of visceral metastasis on oncologic outcomes in metastatic prostate cancer patients treated with combination systemic therapies. We aimed to analyze and compare the efficacy of combination systemic therapies in metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer with or without visceral metastasis.
MATERIALS AND METHODS
Three databases were queried in July 2022 for randomized, controlled trials analyzing metastatic prostate cancer patients treated with combination systemic therapy (androgen receptor signaling inhibitor and/or docetaxel plus androgen deprivation therapy) to standard of care. We analyzed the association between presence of visceral metastases and efficacy of systemic therapies in metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer patients. The main and secondary outcomes of interest were overall survival and progression-free survival, respectively. Formal meta-analysis using fixed-effect model and network meta-analysis using random-effect model were conducted. We followed PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) and AMSTAR (A MeaSurement Tool to Assess systematic Reviews) guidelines.
RESULTS
Overall, 12 and 8 randomized, controlled trials were included for systematic review and meta-analyses/network meta-analyses, respectively. In metastatic hormone-sensitive prostate cancer patients, adding androgen receptor signaling inhibitor to standard of care improved overall survival in patients with visceral metastasis (pooled HR: 0.77, 95% CI: 0.64-0.94) as well as in those without (pooled HR: 0.66, 95% CI: 0.60-0.72; no differences in both across- and within-trial approach; = .13 and = .06, respectively). On the other hand, the progression-free survival benefit from androgen receptor signaling inhibitor + androgen deprivation therapy was significantly lower in patients with visceral metastasis using across-trial approach ( = .03), while it did not reach statistical significance using within-trial approach ( = .14). Analysis of treatment ranking in metastatic hormone-sensitive prostate cancer showed that darolutamide + docetaxel + androgen deprivation therapy had the highest likelihood of improved overall survival irrespective of visceral metastasis. In post-docetaxel metastatic castration-resistant prostate cancer patients, adding androgen receptor signaling inhibitor to androgen deprivation therapy significantly improved overall survival in both patients with visceral metastasis (pooled HR: 0.79, 95% CI: 0.63-0.98) and those without (pooled HR: 0.63, 95% CI: 0.55-0.72). No randomized, controlled trials reported the differential oncologic outcomes stratified by lung vs liver metastases.
CONCLUSIONS
Despite aggressive clinical behavior and worse trajectory of metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer with visceral metastasis, the effectiveness of novel systemic therapies is similar in both metastatic hormone-sensitive prostate cancer and metastatic castration-resistant prostate cancer patients with and without visceral metastasis. Further well-designed studies with detailed visceral metastatic sites and number will enrich the clinical decision-making.

Meta-Analysis Review
OBJECTIVE
To evaluate the efficacy of systemic therapies in patients with worse performance status (PS) treated for high-risk non-metastatic prostate cancer (PCa), metastatic hormone-sensitive PCa (mHSPC), and non-metastatic/metastatic castration-resistant PCa (nmCRPC/mCRPC), as there is sparse pooled data showing the effect of PS on oncological outcomes in patients with PCa.
METHODS
Three databases were queried in June 2022 for randomised controlled trials (RCTs) analysing patients with PCa treated with systemic therapy (i.e., adding androgen receptor signalling inhibitor [ARSI] or docetaxel [DOC] to androgen-deprivation therapy [ADT]). We analysed the oncological outcomes of patients with PCa with worse PS, defined as Eastern Cooperative Oncology Group PS ≥ 1, treated with combination therapies and compared these to patients with good PS. The main outcomes of interest were overall survival (OS), metastasis-free survival (MFS), and progression-free survival.
RESULTS
Overall, 25 and 18 RCTs were included for systematic review and meta-analyses/network meta-analyses, respectively. In all clinical settings, combination systemic therapies significantly improved OS in patients with worse PS as well as in those with good PS, while the MFS benefit from ARSI in the nmCRPC setting was more pronounced in patients with good PS than in those with worse PS (P = 0.002). Analysis of treatment ranking in patients with mHSPC revealed that triplet therapy had the highest likelihood of improved OS irrespective of PS; specifically, adding darolutamide to DOC + ADT had the highest likelihood of improved OS in patients with worse PS. Analyses were limited by the small proportion of patients with a PS ≥ 1 (19%-28%) and that the number of PS 2 was rarely reported.
CONCLUSIONS
Among RCTs, novel systemic therapies seem to benefit the OS of patients with PCa irrespective of PS. Our findings suggest that worse PS should not discourage treatment intensification across all disease stages.

Review
Oral spironolactone has been proposed as a potential treatment for hair loss due to its antiandrogenic properties. However, the efficacy and safety of spironolactone for treating hair loss are not well-established. The objective of this study was to conduct a systematic review of the current literature on the use of oral spironolactone in female pattern hair loss. We conducted a systematic review and meta-analysis of randomized controlled trials and observational studies that assessed the efficacy and safety of oral spironolactone for treating hair loss. We searched for eligible papers in PubMed, Web of Science (ISI), Embase, and Scopus. All analyses were done using R software version 4.2.3 (R Foundation for Statistical Computing, Vienna, Austria). The overall rate of improved hair loss was 56.60%, with a higher rate of improvement (65.80%) observed in the combined therapy group compared to the monotherapy group (43.21%). However, there was significant heterogeneity in the efficacy outcomes, and hair loss did not improve or showed a modest improvement in 37.80% of all patients. The rates of adverse events reported in at least two studies were scalp pruritus or increased scurf (18.92%), menstrual disorders (11.85%), facial hypertrichosis (6.93%), and drug discontinuation (2.79%). The overall adverse events rate was 3.69%, but there was significant heterogeneity in the rates of different adverse events. In conclusion, the present study suggests that spironolactone is an effective and safe treatment option for hair loss. However, further research is needed to fully understand the heterogeneity of treatment response and adverse events and identify factors that may predict treatment response.

Association between RCT methodology and disease indication with mineralocorticoid-related toxicity for patients receiving abiraterone acetate for advanced prostate cancer: A meta-analysis of RCTs.
INTRODUCTION
While abiraterone acetate (AA) has demonstrated survival benefit in advanced prostate cancer (APC), meaningful cardiotoxicity is observed. It is unclear whether the magnitude differs based on disease indication and concurrent steroid administration.
METHODS
We performed a systematic review and meta-analysis of phase II/III RCTs of AA in APC published as of August 11, 2020. Primary outcomes examined were all- and high-grade (grade ≥ 3) hypokalemia and fluid retention, and secondary outcomes included hypertension and cardiac events. We performed random effects meta-analysis comparing intervention (AA + steroid) and control (placebo ± steroid), stratified by treatment indication and whether patients received steroids.
RESULTS
Among 2,739 abstracts, we included 6 relevant studies encompassing 5901 patients. Hypokalemia and fluid retention were observed more frequently among patients receiving AA (odds ratio [OR] 3.10 [95% CI 1.69-5.67] and 1.41 [95% CI 1.19-1.66]). This was modified by whether patients in the control received steroids: trials where control patients did not demonstrated a larger association between AA and hypokalemia (OR 6.88 [95% CI 1.48-2.36] versus OR 1.86 [95% CI 4.97-9.54], P < .0001) and hypertension (OR 2.53 [95% CI 1.91-3.36] vs. OR 1.55 [95% CI 1.17-2.04], P = .1) than those where steroids were administered. We observed heterogeneity due to indication: there were greater effects on hypokalemia (P < 0001), hypertension (P = .03), and cardiac disorders (P = .01) among patients treated for mHSPC than mCRPC.
CONCLUSIONS
The magnitude of cardiotoxicity with AA differs based on trial design and disease indication. These data are valuable in treatment decisions and highlight utilization of appropriate data for counseling.

Meta-Analysis Review
OBJECTIVES
To evaluate the evidence base for patient, oncological, and treatment prognostic factors associated with multiple mental wellbeing outcomes in prostate cancer patients.
METHODS
We performed a literature search of MEDLINE, EMBASE, and CINAHL databases including studies evaluating patient, oncological, or treatment factors against one of five mental wellbeing outcomes; depression, anxiety, fear of cancer recurrence, masculinity, and body image perception. Data synthesis included a random effects meta-analysis for the prognostic effect of individual factors if sufficient homogenous data was available, with a structured narrative synthesis where this was not possible.
RESULTS
A final 62 articles were included. Older age was associated with a reducing odds of depression (OR 0.97, p = 0.04), with little evidence of effect for other outcomes. Additionally, baseline mental health status was related to depression and increasing time since diagnosis was associated with reducing fear of recurrence, albeith with low certainty of evidence. However, few other patient or oncological factors demonstrated any coherent relationship with any wellbeing outcome. Androgen deprivation therapy was associated with increased depression (HR 1.65, 95% CI 1.41-1.92, p < 0.01) and anxiety, however, little difference was seen between other treatment options. Overall, whilst numerous factors were identified, most were evaluated by single studies with few evaluating masculinity and body image outcomes.
CONCLUSION
We highlight the existing evidence for prognostic factors in mental wellbeing outcomes in prostate cancer, allowing us to consider high-risk groups of patients for preventative and treatment measures. However, the current evidence is heterogenous with further work required exploring less conclusive factors and outcomes.

Meta-Analysis
BACKGROUND
Studies using novel antiandrogens (NAA) in patients with metastatic castration-resistant prostate cancer (mCRPC) have shown overall survival benefit. As patients develop resistance to NAA therapy, the poly(ADP-ribose) polymerase inhibitor (PARPi) olaparib in combination with NAA may become a promising therapy. However the overall benefit of olaparib monotherapy or combination therapy still needs to be evaluated. Therefore, we performed a network meta-analysis to assess the efficacy and toxicity between olaparib, olaparib combined with abiraterone and NAA.
METHODS
We searched PubMed, EMBASE, the Cochrane Library and American Society of Clinical Oncology (ASCO) University Meeting abstracts for randomized controlled trials reporting olaparib and NAA from 2010 up to March, 2023. Network meta-analysis using Stata 16.0 and R 4.4.2, hazard ratios (HR) with 95% confidence intervals (CI) were used to assess the results.
RESULTS
Four trials reported olaparib, olaparib plus abiraterone and apalutamide plus abiraterone. radiographic progression-free survival (rPFS) was significantly lower in patients on apalutamide plus abiraterone compared to olaparib (HR, 1.43; 95% CI, 1.06-1.93). rPFS was similar for olaparib plus abiraterone and olaparib (HR, 1.35; 95% CI, 0.99-1.84); likewise, olaparib plus abiraterone and apalutamide plus abiraterone were similar (HR, 1.06; 95% CI, 0.83-1.35). In addition, there was no significant difference between the three interventions for OS. But olaparib has the highest probability of being a preferred treatment for improving rPFS and OS.
CONCLUSION
rPFS was in favor of olaparib compared with apalutamide plus abiraterone. But there were no difference between olaparib plus abiraterone and either olaparib or apalutamide plus abiraterone. Apalutamide plus abiraterone might be the most preferred intervention in cases where AEs are involved.

Meta-Analysis
Impact of disease volume on survival efficacy of triplet therapy for metastatic hormone-sensitive prostate cancer: a systematic review, meta-analysis, and network meta-analysis.
BACKGROUND
Triplet therapy, androgen receptor signaling inhibitors (ARSIs) plus docetaxel plus androgen-deprivation therapy (ADT), is a novel guideline-recommended treatment for metastatic hormone-sensitive prostate cancer (mHSPC). However, the optimal selection of the patient most likely to benefit from triplet therapy remains unclear.
METHODS
We performed a systematic review, meta-analysis, and network meta-analysis to assess the oncologic benefit of triplet therapy in mHSPC patients stratified by disease volume and compare them with doublet treatment regimens. Three databases and meeting abstracts were queried in March 2023 for randomized controlled trials (RCTs) evaluating patients treated with systemic therapy for mHSPC stratified by disease volume. Primary interests of measure were overall survival (OS). We followed the PRISMA guideline and AMSTAR2 checklist.
RESULTS
Overall, eight RCTs were included for meta-analyses and network meta-analyses (NMAs). Triplet therapy outperformed docetaxel plus ADT in terms of OS in both patients with high-(pooled HR: 0.73, 95%CI 0.64-0.84) and low-volume mHSPC (pooled HR: 0.71, 95%CI 0.52-0.97). There was no statistically significant difference between patients with low- vs. high-volume in terms of OS benefit from adding ARSI to docetaxel plus ADT (p = 0.9). Analysis of treatment rankings showed that darolutamide plus docetaxel plus ADT (90%) had the highest likelihood of improved OS in patients with high-volume disease, while enzalutamide plus ADT (84%) had the highest in with low-volume disease.
CONCLUSIONS
Triplet therapy improves OS in mHSPC patients compared to docetaxel-based doublet therapy, irrespective of disease volume. However, based on treatment ranking, triplet therapy should preferably be considered for patients with high-volume mHSPC while those with low-volume are likely to be adequately treated with ARSI + ADT.

Meta-Analysis Review
Prostate cancer ranks as the second most common malignancy in males. Prostate cancer progressing on androgen deprivation therapy (ADT) is castration-resistant prostate cancer (CRPC). Poly-ADP ribose polymerase (PARP) inhibitors (PARPis) have been at the forefront of the treatment of CRPC. We aim to better characterize the progression-free survival (PFS) and overall survival (OS) in metastatic CRPC patients treated with PARPis. A systemic review search was conducted using National Clinical Trial (NCT), PubMed, Embase, Scopus, and Central Cochrane Registry. The improvement in overall survival was statistically significant, favoring PARPis (hazard ratio (HR) 0.855; 95% confidence interval (CI) 0.752-0.974; = 0.018). The improvement in progression-free survival was also statistically significant, with results favoring PARPis (HR 0.626; 95%CI 0.566-0.692; = 0.000). In a subgroup analysis, similar results were observed where the efficacy of PARPis was evaluated in a subgroup of patients without homologous recombination repair (HRR) gene mutation, which showed improvement in PFS favoring PARPis (HR 0.747; 95%CI 0.0.637-0.877; = 0.000). Our meta-analysis of seven RCTs showed that PARPis significantly increased PFS and OS when used with or without antihormonal agents like abiraterone or enzalutamide.

Gender-affirming hormone therapy (GAHT) leads to changes in body composition, secondary sex characteristics and in the distribution and pattern of hair growth. Transgender individuals undergoing GAHT may experience altered hair growth patterns that may be affirming and desirable, or undesirable with a subsequent impact on their quality of life. Given increasing numbers of transgender individuals commencing GAHT worldwide and the clinical relevance of the impact of GAHT on hair growth, we systematically reviewed the existing literature on the impact of GAHT on hair changes and androgenic alopecia (AGA). The majority of studies used grading schemes or subjective measures of hair changes based on patient or investigator's examination. Very few studies used objective quantitative measures of hair parameters but demonstrated statistically significant changes in hair growth length, diameter and density. Feminizing GAHT with estradiol and/or antiandrogens in transgender women may reduce facial and body hair growth and also can improve AGA. Masculinizing GAHT with testosterone in transgender men may increase facial and body hair growth as well as induce or accelerate AGA. The impact of GAHT on hair growth may not align with a transgender person's hair growth goals and specific treatment for AGA and/or hirsutism may be sought. Further research on how GAHT affects hair growth is required.
