Meta-Analysis Review
INTRODUCTION
Sarcopenia is a common skeletal muscle disorder in older people. Here we explore the prevalence of sarcopenia and its impact on men with prostate cancer.
MATERIALS AND METHODS
We searched PubMed, Embase, and Web of Science databases for relevant studies with an explicit definition of sarcopenia in men with prostate cancer which were published between years 2000 and 2022. Prevalence of sarcopenia and its association with time to biochemical recurrence (BCR), progression-free survival (PFS), non-cancer mortality, overall survival (OS), and treatment-related complications in men with prostate cancer were explored. The summary prevalence, hazard ratios (HRs), and 95% confidence intervals (CIs) were calculated.
RESULTS
A total of 24 studies comprising 3,616 patients with early and advanced prostate cancer were included. The prevalence of sarcopenia and sarcopenic obesity was 43.8% (95% CI 19.2%-68.5%) and 24.0% (95% CI 5.0%-43.1%), respectively. Sarcopenia was not associated with a shorter time to BCR (HR 0.89, 95% CI 0.64-1.23, p = 0.48), a shorter PFS (HR 1.20, 95% CI 0.73-1.97, p = 0.48), or a shorter OS (HR 1.29, 95% CI 0.90-1.85, p = 0.16). In contrast, sarcopenia was significantly associated with a higher non-cancer mortality (HR 1.85, 95% CI 1.23-2.80, p = 0.003). In four out of five studies eligible for assessment, sarcopenia was not associated with an increased risk of treatment-related complications.
DISCUSSION
Sarcopenia increases the risk of death from other causes in men with prostate cancer. Patients with prostate cancer should be assessed and managed for sarcopenia in everyday clinical practice.

Meta-Analysis Review
Addition of androgen receptor-targeted agents to androgen-deprivation therapy and docetaxel in metastatic hormone-sensitive prostate cancer: a systematic review and meta-analysis.
BACKGROUND
Androgen-deprivation therapy (ADT) historically represented the milestone for the treatment of metastatic hormone-sensitive prostate cancer (mHSPC). Recently, combining androgen receptor-targeted agents (ARTA) or docetaxel with ADT significantly improved clinical outcomes in this setting. The efficacy of the combined use of an ARTA with docetaxel and ADT (triplet), however, was unknown, and often conflicting data derived from subgroup analysis of randomized phase III trials. In order to better define the benefits and risks of the triplet in mHSPC, we carried out a systematic review and meta-analysis of available clinical trials.
METHODS
A literature search with no data restriction using Medline/PubMed, the Cochrane Library, and American Society of Clinical Oncology/European Society for Medical Oncology (ASCO/ESMO) Meeting abstracts was carried out up to April 2022. The meta-analysis was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statements. Overall survival (OS) was the primary endpoint; progression-free survival (PFS) and safety were secondary endpoints. For OS and PFS, summary hazard ratios (HRs) were calculated; for safety, risk ratio (RR) was assessed. Random- or fixed-effects models were used, depending on studies heterogeneity.
RESULTS
Five randomized clinical trials fulfilled the prespecified inclusion criteria. The triplet significantly improved OS (fixed-effect, HR = 0.74; P < 0.00001) and PFS (fixed-effect; HR = 0.50 for clinical PFS, HR = 0.49 for radiological PFS; P < 0.0001) compared with docetaxel plus ADT. We did not show heterogeneity between treatment efficacy and the disease burden, metachronous versus synchronous presentation, concomitant versus sequential strategy. Compared with docetaxel + ADT, the triplet did not increase the risk of adverse events (AEs) (RR = 1.00, P = 0.27 for any-grade AEs; RR = 1.13, P = 0.14 for severe AEs), except for severe hypertension (RR = 1.73, P = 0.001).
CONCLUSIONS
Emerging evidence supports the combination of an ARTA plus docetaxel and ADT in mHSPC patients. Given the availability of several strategies in this setting, clinical characteristics and drug safety profile may help clinicians select the appropriate treatment for mHSPC patients who are more likely to benefit from treatment intensification.

Review
Prostate cancer is the third most common cancer in men globally, and the most common cancer among men in the United States. Dietary choices may play an important role in developing prostate cancer; in particular, a higher dairy product intake has been associated with an increased risk of developing prostate cancer. The overall positive association between milk consumption and the risk of prostate cancer development and prostate cancer mortality has been well documented in multiple epidemiological studies. However, there is limited literature on the association between types of milk, as classified by fat content (skim, low fat, and whole), and the risk of developing prostate cancer. When further examining current state of the literature on this topic, there is a number of epidemiologic studies assessing the relationship between prostate cancer and milk consumption. On the contrary, very few experimental studies explore this topic. Further experimental research may be necessary to examine the relationship between dairy and dairy products consumption and the increased risk of development of prostate cancer. At this time, there are no formal clinical recommendations regarding dairy products consumption for patients who are at risk of prostate cancer development or who have a history of prostate cancer. In this manuscript, we sought to systematically review the existing literature on the association between milk consumption classified by fat content, and the risk of developing prostate cancer. These findings may be useful for the clinicians who provide recommendations for the patients at risk of developing prostate cancer.

Review
INTRODUCTION
Radiographic staging with bone scan or computed tomography is not indicated for men with low-risk prostate cancer. Physician compliance with these imaging recommendations has been widely variable, leading to inappropriate testing and increased costs. The purpose of this systematic review was to identify and learn from interventions associated with improved physician compliance to imaging guidelines for prostate cancer staging.
METHODS
This systematic review followed Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. PubMed was searched through January 2022 for the following medical subject headings (MeSH) terms: ('practice patterns, physicians' or 'guideline adherence' or 'unnecessary procedures' or 'quality improvement') and ('prostatic neoplasms/diagnostic imaging'). Inclusion required discussion of an intervention for physician compliance to prostate cancer imaging guidelines and specific data describing associated outcomes. Publications focused on other malignancies or without this intervention, evaluation, or data were excluded.
RESULTS
Of 82 papers screened, only five met inclusion criteria - representing 12 802 patients. Each focused on reducing unnecessary imaging and demonstrated statistically significant post-intervention improvement of physician compliance to imaging guidelines for staging prostate cancer. Four were multidimensional, with education, clinical champions, and performance feedback. One used the unidimensional intervention of an electronic medical record (EMR)-based clinical reminder order check (CROC). No studies used randomization or a control group.
CONCLUSIONS
Post-intervention improvement in physician compliance to imaging guidelines for staging prostate cancer has been associated with EMR-based CROC and combination interventions using clinical champions, education, and feedback. This has been observed at individual institutions and larger organizations spanning a region or state.

Meta-Analysis
IMPORTANCE
Multiple strategies integrating magnetic resonance imaging (MRI) and clinical data have been proposed to determine the need for a prostate biopsy in men with suspected clinically significant prostate cancer (csPCa) (Gleason score ≥3 + 4). However, inconsistencies across different strategies create challenges for drawing a definitive conclusion.
OBJECTIVE
To determine the optimal prostate biopsy decision-making strategy for avoiding unnecessary biopsies and minimizing the risk of missing csPCa by combining MRI Prostate Imaging Reporting & Data System (PI-RADS) and clinical data.
DATA SOURCES
PubMed, Ovid MEDLINE, Embase, Web of Science, and Cochrane Library from inception to July 1, 2022.
STUDY SELECTION
English-language studies that evaluated men with suspected but not confirmed csPCa who underwent MRI PI-RADS followed by prostate biopsy were included. Each study had proposed a biopsy plan by combining PI-RADS and clinical data.
DATA EXTRACTION AND SYNTHESIS
Studies were independently assessed for eligibility for inclusion. Quality of studies was appraised using the Quality Assessment of Diagnostic Accuracy Studies 2 tool and the Newcastle-Ottawa Scale. Mixed-effects meta-analyses and meta-regression models with multimodel inference were performed. Reporting of this study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline.
MAIN OUTCOMES AND MEASURES
Independent risk factors of csPCa were determined by performing meta-regression between the rate of csPCa and PI-RADS and clinical parameters. Yields of different biopsy strategies were assessed by performing diagnostic meta-analysis.
RESULTS
The analyses included 72 studies comprising 36 366 patients. Univariable meta-regression showed that PI-RADS 4 (β-coefficient [SE], 7.82 [3.85]; P = .045) and PI-RADS 5 (β-coefficient [SE], 23.18 [4.46]; P < .001) lesions, but not PI-RADS 3 lesions (β-coefficient [SE], -4.08 [3.06]; P = .19), were significantly associated with a higher risk of csPCa. When considered jointly in a multivariable model, prostate-specific antigen density (PSAD) was the only clinical variable significantly associated with csPCa (β-coefficient [SE], 15.50 [5.14]; P < .001) besides PI-RADS 5 (β-coefficient [SE], 9.19 [3.33]; P < .001). Avoiding biopsy in patients with lesions with PI-RADS category of 3 or less and PSAD less than 0.10 (vs <0.15) ng/mL2 resulted in reducing 30% (vs 48%) of unnecessary biopsies (compared with performing biopsy in all suspected patients), with an estimated sensitivity of 97% (vs 95%) and number needed to harm of 17 (vs 15).
CONCLUSIONS AND RELEVANCE
These findings suggest that in patients with suspected csPCa, patient-tailored prostate biopsy decisions based on PI-RADS and PSAD could prevent unnecessary procedures while maintaining high sensitivity.

Review
INTRODUCTION
Hematospermia is an uncommon symptom but can cause significant anxiety among the patient and his partner. The available data on the underlying etiology, management and outcome are variable and inconsistent. This systematic review was aimed to describe the clinical characteristics, etiology, treatment and outcomes of hematospermia.
METHODS
Keywords were searched in PubMed, Scopus, LILACS and Google Scholar. Relevant articles were manually added from the list of references of eligible articles. Studies with a considerable assessment of patients with hematospermia were included. Qualitative analysis was performed using the available data.
RESULTS
Twenty studies (Fifteen prospective and five retrospective, n=2079 patients, mean age =46.2 (range: 15-89) years) were eligible. Community screening reported a 0.5% prevalence of hematospermia (one study). Majority had hematospermia as the main/only symptom while dysuria (n=38/232, 16.4%), lower urinary tract symptoms (n=113/833, 13.6%), Hematuria (65/566, 11.5%) and testicular pain (n=68/631, 10.7%), were associated in some patients. Suspicious rectal examination (one study) and elevated PSA (Prostate Specific Antigen) levels (four studies) were indicative of sinister pathologies. Common etiologies were urogenital infections/inflammatory conditions followed by prostatic, seminal vesicular or urethral calculi. Malignancies were detected in 5.4% (n=74/1362, 11 studies) of patients >40 years old and the majority had prostate cancers (67/74, 90.5%). Etiology was unknown in 51.8% (n=603/1163). Definitive treatment of the underlying etiology (n=260/347, 74.9%) resolved the symptoms while spontaneous resolution occurred in the vast majority 88.9% (n=168/189) with unknown etiology.
CONCLUSIONS
Hematospermia is relatively an innocent symptom. Malignancies are rare and occurred in men over 40 years. Clinical assessment including a rectal examination and a PSA level would be sufficient to identify most causes. Urogenital infections/inflammation and prostatic calculi are the commonly found etiologies. There was no identifiable cause in almost half of those with hematospermia. The majority has a benign course.

Meta-Analysis Review
PURPOSE
The reliability of magnetic resonance imaging (MRI) as a local and nodal staging tool in radio-recurrent prostate cancer (PCa) is still unclear. The present study aims at evaluating the predictive value of MRI in the detection of extracapsular extension (ECE), seminal vesical invasion (SVI) and nodal involvement (LNI) in patients after primary radio (EBRT) and/or brachytherapy (BT) before salvage radical prostatectomy (SRP).
METHODS
This systematic review and meta-analysis were performed in line with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Pubmed, Scopus, and Web of Science databases were systemically reviewed to extract the data on diagnostic performance of MRI in radio-recurrent PCa.
RESULTS
Four studies comprising 94 radio-recurrent PCa patients were included. The pooled prevalence of ECE, SVI, and LNI was 61%, 41%, and 20%, respectively. The pooled sensitivity for ECE, SVI and LNI detection was 53% (CI 95% 19.8-83.6%), 53% (CI 95% 37.2-68%) and 33% (CI 95% 4.7-83.1%) respectively, whereas specificity was 75% (CI 95% 40.6-92.6%), 88% (CI 95% 71.7-95.9%) and 92% (CI 95% 79.6-96.8%). The sensitivity analysis revealed that a single outlying study using only T2-weighted imaging instead of multiparametric MRI reported significantly higher sensitivity with significantly lower specificity.
CONCLUSIONS
This is the first meta-analysis reporting reliability of staging MRI in a radio-recurrent setting. MRI provides poor sensitivity while maintaining high specificity for local and nodal staging before SRP. However, current evidence is limited to the low number of heterogenous studies at meaningful risk of bias.

Meta-Analysis
INTRODUCTION
Testosterone replacement therapy (TRT) is a generally accepted method treating for aging-related late-onset hypogonadism (LOH). However, the efficacy and safety of TRT remain controversial. An updated systematic review and meta-analysis aimed to determine the effectiveness and security of TRT treating for LOH.
METHODS
Randomized controlled trials (RCTs) of TRT for LOH were searched in the databases of Pubmed, Embase, Clinicaltrials.gov and Cochrane from 1990 to 2023 and an updated meta-analysis was conducted.
RESULTS
The results of 28 RCTs involving 3461 patients were included and scrutinized in this analysis. Among these, 11 RCTs were of long-term duration (≥12 months), while 18 RCTs were short-term studies (<12 months) comparing TRT with a placebo. TRT modalities comprised injection, oral administration, and transdermal administration. International Index of Erectile Function (IIEF) (Weighted Mean difference (WMD) 3.26; 95%; 95% confidence interval (CI) 1.654.88; P<0.0001) was obviously improved in the TRT group. International Prostate Symptom Score (IPSS) (WMD 0.00; 95% CI -0.450.45; P=1.0), Prostate Volume (PV) (WMD 0.38; 95% CI -0.641.41; P=0.46), Maximum Flow Rate (Qmax) (WMD 1.86; 95% CI -0.984.69; P=0.20), Postvoid Residual Urine Volume (PVR) (WMD 3.20; 95% CI -5.8712.28; P=0.49) and Prostate-Specific Antigen (PSA) (WMD 0.08; 95% CI -0.000.17; P=0.06) were not significantly statistical between two groups.
CONCLUSION
This meta-analysis reveals that TRT could improve the IIEF score of hypogonadal men without detriment to the IPSS score, PV, Qmax, PVR and PSA regardless of the administration method or duration of treatment.The meta-analysis was registered at PROSPERO (CRD42023413434).

Meta-Analysis Review
BACKGROUND
Globally prostate cancer is one of the most prevalent cancer among men and a leading cause of morbidity and mortality, especially in a developing country, which is mainly due to lack of knowledge and awareness regarding the screening of prostate cancer. The main objective of this review and meta-analysis is to evaluate the knowledge, awareness and practice of adult men about prostate cancer.
METHOD
An extensive literature search was performed on studies published between January 2000 to 2021. The systematic review initially yielded 137 studies, out of which 7 studies were covered on this meta-evaluation.
RESULT
We noted that the pooled estimate of knowledge and awareness were respectively 65% [CI: 29%, 100%], and 74% [CI: 66%, 82%] about prostate cancer. However, there were limited practices noted in screening of prostate cancer.
CONCLUSION
In order to increase the awareness and screening practice rate for prostate cancer, an improved health education is highly recommended.

Meta-Analysis Review
OBJECTIVE
Although single-fraction high-dose-rate brachytherapy (SFHDR) for localized prostate cancer has been tried in clinical trials, relevant medical evidence is currently lacking. It is necessary to systematically analyze the safety and efficacy of SFHDR.
METHODS
Comprehensive and systematic searches for eligible studies were performed in PubMed, Embase, and the Cochrane Library databases. The primary endpoints included safety and efficacy, represented by toxic effects and biochemical recurrence-free survival (bRFS), respectively. The proportion rates were used as the effect measure for each study and were presented with corresponding 95% confidence intervals (CI) and related 95% prediction interval (PI). Restricted maximum-likelihood estimator (REML) and the Hartung-Knapp method were used in the meta-analysis.
RESULTS
Twenty-five studies met the inclusion criteria for quantitative analysis, including 1440 patients. The median age of patients was 66.9 years old (62-73 years old) and the median follow-up was 47.5 months (12-75 months). The estimates of cumulative occurrence for severe gastrointestinal (GI) and genitourinary (GU) toxic effects were 0.1% (95% CI 0-0.2%) and 0.4% (95% CI 0-1.2%), and for grade 2 toxic effects were 1.6% (95% CI 0.1-4.7%) and 17.1% (95% CI 5.4-33.5%), respectively. The estimate of 3‑year bRFS was 87.5% (95% CI 84.4-90.3%) and 71.0% (95% CI 63.0-78.3%) for 5‑year bRFS. The pooled bRFS rates for low-risk patients were 99.0% (95% CI 85.2-100.0%) at 3 years and 80.9% (95% CI 75.4-85.9%) at 5 years, and the risk group was found to be statistically correlated with bRFS (3-year bRFS, P < 0.01; 5‑year bRFS, P = 0.04).
CONCLUSION
SFHDR is associated with favorable tolerability and suboptimal clinical benefit in patients with localized prostate cancer. Ongoing and planned high-quality prospective studies are necessary to verify its safety and efficacy.
