Meta-Analysis Review
The efficacy and safety of low-intensity extracorporeal shock wave treatment combined with or without medications in Chronic prostatitis/chronic pelvic pain syndrome: a systematic review and meta-analysis.
BACKGROUND
We performed this systematic review and meta-analysis to investigate the efficacy and safety of Li-ESWT combined with or without medications for patients with Chronic prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS).
METHODS
A comprehensive search was conducted of PUBMED, Cochrane Library, and Web of Science databases from inception to February 2022 for randomized controlled trials (RCTs) assessing the efficacy and safety of Li-ESWT with or without the combination of medications compared with the control group. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), Visual Analogue Scale/Score (VAS), International Index of Erectile Function (IIEF), and International prostate symptom score (IPSS) were used to assess the improvements of symptoms in CP/CPPS patients.
RESULTS
651 patients from 12 randomized controlled studies were included in this study. The total NIH-CPSI scores, pain domain scores, and quality of life (QOL) scores were significantly lower in the Li-ESWT group than those in the control group at the termination of treatment, and 1, 4, 12, and 24 weeks after treatment. And these scores were significantly reduced in the Li-ESWT group than in baselines. In the subgroup analysis, reductions of these scores lasted longer and were greater in Li-ESWT combined with medications than in Li-ESWT alone. In the Li-ESWT group, the VAS score; IIEF score; and IPSS score were significant improvements than those in control group at the termination of treatment, and 1, 4, and 12 weeks after treatment; 4, 12, and 24 weeks after treatment; and 1, 4, and 12 weeks after treatment, respectively.
CONCLUSIONS
Li-ESWT is a safe, non-invasive, and effective option for patients with CP/CPPS, whether combined with medications or not, should be recommended for widespread use in clinical practice.

Impact of Epithelial Histological Types, Subtypes, and Growth Patterns on Oncological Outcomes for Patients with Nonmetastatic Prostate Cancer Treated with Curative Intent: A Systematic Review.
CONTEXT
The optimal management for men with prostate cancer (PCa) with unconventional histology (UH) is unknown. The outcome for these cancers might be worse than for conventional PCa and so different approaches may be needed.
OBJECTIVE
To compare oncological outcomes for conventional and UH PCa in men with localized disease treated with curative intent.
EVIDENCE ACQUISITION
A systematic review adhering to the Referred Reporting Items for Systematic Reviews and Meta-Analyses was prospectively registered on PROSPERO (CRD42022296013) was performed in July 2021.
EVIDENCE SYNTHESIS
We screened 3651 manuscripts and identified 46 eligible studies (reporting on 1 871 814 men with conventional PCa and 6929 men with 10 different PCa UHs). Extraprostatic extension and lymph node metastases, but not positive margin rates, were more common with UH PCa than with conventional tumors. PCa cases with cribriform pattern, intraductal carcinoma, or ductal adenocarcinoma had higher rates of biochemical recurrence and metastases after radical prostatectomy than for conventional PCa cases. Lower cancer-specific survival rates were observed for mixed cribriform/intraductal and cribriform PCa. By contrast, pathological findings and oncological outcomes for mucinous and prostatic intraepithelial neoplasia (PIN)-like PCa were similar to those for conventional PCa. Limitations of this review include low-quality studies, a risk of reporting bias, and a scarcity of studies that included radiotherapy.
CONCLUSIONS
Intraductal, cribriform, and ductal UHs may have worse oncological outcomes than for conventional and mucinous or PIN-like PCa. Alternative treatment approaches need to be evaluated in men with these cancers.
PATIENT SUMMARY
We reviewed the literature to explore whether prostate cancers with unconventional growth patterns behave differently to conventional prostate cancers. We found that some unconventional growth patterns have worse outcomes, so we need to investigate if they need different treatments. Urologists should be aware of these growth patterns and their clinical impact.

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.

Meta-Analysis
A Systematic Review and Meta-analysis of the Effectiveness and Toxicities of Lutetium-177-labeled Prostate-specific Membrane Antigen-targeted Radioligand Therapy in Metastatic Castration-Resistant Prostate Cancer.
CONTEXT
Castration-resistant prostate cancer (CRPC) treatment is an evolving challenge. Prostate-specific membrane antigen (PSMA)-targeted endoradiotherapy/radioligand therapy (PRLT) with small-molecule, urea-based agents labeled with the β-particle-emitting radionuclide lutetium-177 (Lu) is a promising new approach.
OBJECTIVE
In this systematic review and meta-analysis, we evaluated the efficacy and toxicity of PRLT.
EVIDENCE ACQUISITION
A systematic search was performed in PubMed/Medline (last updated February 18, 2019). A total of 250 studies were reviewed, and 24 studies with 1192 patients were included in the analysis. Proportions of patients with ≥50% serum prostate-specific antigen (PSA) decrease, any PSA decrease, and any PSA increase were extracted. Proportions of patients showing any grade toxicity and those with grade 3/4 toxicities based on Common Terminology Criteria for Adverse Events (CTCAE) grading were extracted from manuscripts. Overall survival and progression-free survival were evaluated. A meta-analysis of single proportions was carried out. Furthermore, we compared the two most common PRLT agents, Lu-PSMA with Lu-PSMA-I&T, for effectiveness and toxicity.
EVIDENCE SYNTHESIS
Among the 24 included studies, 20 included data on Lu-PSMA-617, three included data on Lu-PSMA-I&T, and one study had aggregated data for Lu-PSMA-617 and Lu-PSMA-I&T. The estimated proportion of Lu-PSMA-617-treated patients who showed a serum PSA decrease of ≥50% with at least an 8-wk interval between therapy and PSA measurement was 0.44 (0.39; 0.50). Therapy with Lu-PSMA-I&T demonstrated an estimated proportion of patients with ≥50% PSA reduction to be 0.36 (0.26; 0.47). The aggregate results for men treated with more than one cycle of any kind of PRLT showed an estimated proportion of 0.46 (0.41; 0.51) for PSA response ≥50%. Regarding aggregate data from all of the PRLT agents, we found that grade 3 and 4 toxicities were uncommon, with estimated proportions from 0.01 (0.00;0.04) for nausea, fatigue, diarrhea, and elevated aspartate transaminase up to 0.08 (0.05; 0.12) for anemia. There was considerable heterogeneity among the studies in the "any-grade toxicity" groups. Meta-regression showed that more than one cycle of PRLT is associated with a greater proportion of patients with ≥50% PSA reduction. Overall survival according to pooled hazard ratios (HRs) for any PSA decline was 0.29 (0.18; 0.46), and for >50% PSA reduction was 0.67 (0.43; 1.07). Progression-free survival according to a pooled HR of >50% PSA reduction was 0.53 (0.32; 0.86).
CONCLUSIONS
The relatively high number of PSA responders alongside the low rate of severe toxicity reflects the potentially promising role of PRLT in treating CRPC. The ultimate utility of this treatment modality will become clearer as multiple prospective studies continue to accrue. In the interim, this systematic review and meta-analysis can serve as a compendium of effectiveness and adverse events associated with PRLT for treating clinicians.
PATIENT SUMMARY
Prostate-specific membrane antigen-targeted endoradiotherapy/radioligand therapy (PRLT) is associated with ≥50% reduction in prostate-specific antigen level in a large number of patients and a low rate of toxicity, reflecting its potential in treating castration-resistant prostate cancer. This systematic review and meta-analysis presents as a compendium of the effectiveness and adverse events related to PRLT for treating clinicians.

Meta-Analysis Review
Perioperative, function, and positive surgical margin in extraperitoneal versus transperitoneal single port robot-assisted radical prostatectomy: a systematic review and meta-analysis.
BACKGROUND
Extraperitoneal and transperitoneal approaches are two common modalities in single-port (SP) robot-assisted radical prostatectomy (RARP), but differences in safety and efficacy between the two remain controversial. This study aimed to compare the perioperative, function, and positive surgical margin of extraperitoneal with transperitoneal approaches SP-RARP.
METHODS
Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, this study is registered with PROSPERO (CRD 42023409667). We systematically searched databases including PubMed, Embase, Web of Science, and Cochrane Library to identify relevant studies published up to February 2023. Stata 15.1 software was used to analyze and calculate the risk ratio (RR) and weighted mean difference (WMD).
RESULTS
A total of five studies, including 833 participants, were included in this study. The SP-TPRP group is superior to the SP-EPRP group in intraoperative blood loss (WMD: - 43.92, 95% CI - 69.81, - 18.04; p = 0.001), the incidence of postoperative Clavien-Dindo grade II and above complications (RR: 0.55, 95% CI - 0.31, 0.99; p = 0.04), and postoperative continence recovery (RR: 1.23, 95% CI 1.05, 1.45; p = 0.04). Conversely, the hospitalization stays (WMD: 7.88, 95% confidence interval: 0.65, 15.1; p = 0.03) for the SP-EPRP group was shorter than that of the SP-TPRP group. However, there was no significant difference in operation time, postoperative pain score, total incidence of postoperative complications, and positive surgical margin (PSM) rates between the two groups (p > 0.05).
CONCLUSIONS
This study demonstrates that both extraperitoneal and extraperitoneal SP-RARP approaches are safe and effective. SP-TPRP is superior to SP-EPRP in postoperative blood loss, the incidence of postoperative Clavien-Dindo grade II and above complications, and postoperative continence recovery, but it is accompanied by longer hospital stays.

Meta-Analysis
BACKGROUND
Chronic prostatitis (CP) is a common condition that affects many individuals. Previous clinical trials have explored the use of moxibustion as a potential treatment for CP. However, the evidence on the effectiveness of moxibustion for CP remains limited. Therefore, this study aimed to comprehensively assess the effects of moxibustion for CP.
METHODS
In order to gather relevant and up-to-date information, we conducted a systematic literature search of databases including Cochrane Library, PUBMED, EMBASE, CNKI, and Wangfang from inception until June 30, 2023. Only randomized clinical trials (RCTs) that investigated the use of moxibustion for CP were included in this study. The primary outcomes of interest were the National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) scores and the overall response rate. To evaluate the quality of the included studies, we used the Cochrane risk-of-bias tool.
RESULTS
After analyzing the data from 8 RCTs involving a total of 664 patients, we found significant differences in NIH-CPSI scores between moxibustion and other treatment modalities. Specifically, when compared with herbal medicine, moxibustion was associated with a mean difference (MD) of -1.78 in NIH-CPSI scores (95% confidence interval [CI] [-2.78, -0.78], P < .001), and when compared with western medicine, moxibustion was associated with a MD of -5.24 in NIH-CPSI scores (95% CI [-7.80, -2.67], P < .08). In terms of the overall response rate, moxibustion was found to be superior to herbal medicine, with a MD of 2.36 (95% [19, 4.67], P = .01). Additionally, when moxibustion was combined with herbal medicine, it yielded a higher overall response rate with a MD of 4.07 (95% CI [1.54, 10.74], P = .005) compared to herbal medicine alone. Moxibustion also outperformed western medicine in terms of the overall response rate, with a MD of 4.56 (95% CI [2.24, 9.26], P < .001).
CONCLUSION
Based on the findings of this study, moxibustion appears to be a potentially efficacious treatment for CP. The results suggest that moxibustion can improve NIH-CPSI scores and overall response rate in patients with CP. However, further high-quality studies are needed to validate these results and establish the long-term effects of moxibustion as a treatment for CP.

Meta-Analysis
BACKGROUND
Actinium-225 (Ac-225) labelled PSMA RLT has been tested recently in metastatic castration-resistant prostate cancer (mCRPC), with encouraging results. Ac-225, being an alpha emitter, is expected to have higher efficacy and fewer side effects compared to the beta-emitters such as Lutetium-177. We have performed a meta-analysis to assess the therapeutic responses, survival effects, and significant side effects of Ac-225 PSMA RLT in patients with mCRPC.
METHODOLOGY
Systematic literature search was carried out from five electronic databases PubMed/MEDLINE, SCOPUS, EMBASE, Web of Science, and Cochrane Library until March 2021. Eight studies were found to be eligible for this metanalysis.
RESULTS
Eight studies with 226 patients were analyzed in this metanalysis. 81% (95% CI 73-89) patients had a decline in PSA levels. 60% of the patients showed more than 50% PSA decline. Two studies assessed survival effects of radioligand naïve patients compared to patients who had received Lu-PSMA therapy previously and the pooled HR for radioligand naïve patients is 0.22. The most common toxicity reported was xerostomia in 167 patients out of 226 patients (73.9%, 95% CI 67.6-79.5%); however, most of them were confined to grade I and II levels. Other reported side effects include hematologic toxicity and nephrotoxicity.
CONCLUSION
Ac-PSMA RLT is a safe and potentially effective treatment option for patients with mCRPC.

Meta-Analysis
IMPORTANCE
As the field of medicine strives for equity in care, research showing the association of social determinants of health (SDOH) with poorer health care outcomes is needed to better inform quality improvement strategies.
OBJECTIVE
To evaluate the association of SDOH with prostate cancer-specific mortality (PCSM) and overall survival (OS) among Black and White patients with prostate cancer.
DATA SOURCES
A MEDLINE search was performed of prostate cancer comparative effectiveness research from January 1, 1960, to June 5, 2020.
STUDY SELECTION
Two authors independently selected studies conducted among patients within the United States and performed comparative outcome analysis between Black and White patients. Studies were required to report time-to-event outcomes. A total of 251 studies were identified for review.
DATA EXTRACTION AND SYNTHESIS
Three authors independently screened and extracted data. End point meta-analyses were performed using both fixed-effects and random-effects models. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed, and 2 authors independently reviewed all steps. All conflicts were resolved by consensus.
MAIN OUTCOMES AND MEASURES
The primary outcome was PCSM, and the secondary outcome was OS. With the US Department of Health and Human Services Healthy People 2030 initiative, an SDOH scoring system was incorporated to evaluate the association of SDOH with the predefined end points. The covariables included in the scoring system were age, comorbidities, insurance status, income status, extent of disease, geography, standardized treatment, and equitable and harmonized insurance benefits. The scoring system was discretized into 3 categories: high (≥10 points), intermediate (5-9 points), and low (<5 points).
RESULTS
The 47 studies identified comprised 1 019 908 patients (176 028 Black men and 843 880 White men; median age, 66.4 years [IQR, 64.8-69.0 years]). The median follow-up was 66.0 months (IQR, 41.5-91.4 months). Pooled estimates found no statistically significant difference in PCSM for Black patients compared with White patients (hazard ratio [HR], 1.08 [95% CI, 0.99-1.19]; P = .08); results were similar for OS (HR, 1.01 [95% CI, 0.95-1.07]; P = .68). There was a significant race-SDOH interaction for both PCSM (regression coefficient, -0.041 [95% CI, -0.059 to 0.023]; P < .001) and OS (meta-regression coefficient, -0.017 [95% CI, -0.033 to -0.002]; P = .03). In studies with minimal accounting for SDOH (<5-point score), Black patients had significantly higher PCSM compared with White patients (HR, 1.29; 95% CI, 1.17-1.41; P < .001). In studies with greater accounting for SDOH variables (≥10-point score), PCSM was significantly lower among Black patients compared with White patients (HR, 0.86; 95% CI, 0.77-0.96; P = .02).
CONCLUSIONS AND RELEVANCE
The findings of this meta-analysis suggest that there is a significant interaction between race and SDOH with respect to PCSM and OS among men with prostate cancer. Incorporating SDOH variables into data collection and analyses are vital to developing strategies for achieving equity.

European Urology Jan 2017Focal therapy of prostate cancer has been proposed as an alternative to whole-gland treatments. (Review)
Review
CONTEXT
Focal therapy of prostate cancer has been proposed as an alternative to whole-gland treatments.
OBJECTIVE
To summarize the evidence regarding sources of energy employed in focal therapy.
EVIDENCE ACQUISITION
Embase and Medline (PubMed) were searched from 1996 to October 31, 2015 following the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. Ongoing trials were selected from electronic registries. The stage of assessment of each source of energy was determined using the Idea, Development, Exploration, Assessment, Long-term study recommendations.
EVIDENCE SYNTHESIS
Thirty-seven articles reporting on 3230 patients undergoing focal therapy were selected. Thirteen reported on high-intensity focused ultrasound, 11 on cryotherapy, three on photodynamic therapy, four on laser interstitial thermotherapy, two on brachytherapy, three on irreversible electroporation, and one on radiofrequency. High-intensity focused ultrasound, cryotherapy, photodynamic therapy, and brachytherapy have been assessed in up to Stage 2b studies. Laser interstitial thermotherapy and irreversible electroporation have been evaluated in up to Stage 2a studies. Radiofrequency has been evaluated in one Stage 1 study. Median follow-up varied between 4 mo and 61 mo, and the median rate of serious adverse events ranged between 0% and 10.6%. Pad-free leak-free continence and potency were obtained in 83.3-100% and 81.5-100%, respectively. In series with intention to treat, the median rate of significant and insignificant disease at control biopsy varied between 0% and 13.4% and 5.1% and 45.9%, respectively. The main limitations were the length of follow-up, the absence of a comparator arm, and study heterogeneity.
CONCLUSIONS
Focal therapy has been evaluated using seven sources of energy in single-arm retrospective and prospective development studies up to Stage 2b. Focal therapy seems to have a minor impact on quality of life and genito-urinary function. Oncological effectiveness is yet to be defined against standard of care.
PATIENT SUMMARY
Seven sources of energy have been employed to selectively ablate discrete areas of prostate cancer. There is high evidence that focal therapy is safe and has low detrimental impact on continence and potency. The oncological outcome has yet to be evaluated against standard of care.

Meta-Analysis
BACKGROUND
Benign prostatic hyperplasia (BPH) is a common chronic condition among men aged 50 or older, causing voiding and obstructive lower urinary tract symptoms. Water vapor thermal therapy (WVTT) using the Rezūm® system is a new minimally invasive surgical technique that is increasingly reported as a treatment for BPH.
METHODS
The protocol was submitted to the PROSPERO registry. We searched PubMed, Web of Science, Embase, Cochrane Library and ClinicalTrials.gov up to July 29, 2022. Quality assessment was carried out by a 20-item checklist form prepared by the Institute of Health Economics (IHE). Double arcsine transformation was performed to stabilize the variance of the original ratio. When I > 50%, the random effect model was used to calculate the pooled parameters. Otherwise, the fixed effect model was used. 95% confidence intervals (CIs) were calculated. A leave-one-out sensitivity analysis was performed to evaluate the impact of each study on the pooled outcomes, and finally, Egger's test was used to assess publication bias.
RESULTS
A total of seven single-arm observational studies and one random controlled trial, including 1015 patients, were included. One year after WVTT, the International Prostate Symptom Score decreased by 11.37 (95% CI: -12.53, -10.21), the IPSS Quality of Life scale decreased by 2.59 (95% CI: -2.92, -2.26), the maximum urine flow rate increased by 5.26 ml/s (95% CI: 4.53, 5.99), and the postvoid residual decreased by 13.18 ml (95% CI: -24.32, -2.03). The most common complication was dysuria, with a pooled incidence of 21% (95% CI: 14%, 29%), and the second most common complication was hematuria, with a pooled incidence of 14% (95% CI: 10%, 18%). The pooled incidence of retreatment was 3% (95% CI: 2%, 5%).
CONCLUSIONS
WVTT is an attractive alternative to medication or more invasive surgical procedures and can serve as first-line therapy for men with BPH.
