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.

Review
Preclinical and clinical studies have suggested potential synergies of combining poly (ADP-ribose) polymerase (PARP) inhibitors and novel hormonal therapies (NHT) for patients with metastatic castration-resistant prostate cancer (mCRPC). We systematically searched PubMed, ClinicalTrials.gov and ASCO-GU annual meeting abstracts up to March 2023 to identify potential phase III trials reporting the use of combining PARP inhibitors with NHT in the first-line setting for mCRPC. A total of four phase III trials met the criteria for subsequent review. Emerging data suggested that the radiographic progression-free survival (rPFS) was significantly longer in the PARP inhibitor combined with NHT group versus the placebo plus NHT group for the first-line setting of biomarker-unselected mCRPC patients, especially for patients with homologous recombination repair (HRR) mutation (HRR m), and with the greatest benefit for BRCA1/2 mutation (BRCA1/2 m) populations. Final overall survival (OS) data of the PROpel trial indicated a significant improvement in median OS for mCRPC patients with HRR m and BRCA1/2 m receiving olaparib + abiraterone. Prior taxane-based chemotherapy might not influence the efficacy of the combination. Compared with the current standard-of-care therapies, combining NHT with PARP inhibitors could achieve a significant survival benefit in the first-line setting for mCRPC patients with HRR and BRCA1/2 mutations.

Review
PURPOSE
To compare biochemical recurrence, sexual potency and urinary continence outcomes of ablative therapy and radical treatment (radical prostatectomy or radiotherapy with androgen deprivation therapy).
MATERIAL AND METHODS
A systematic review and meta-analysis followed the PRISMA guidelines were performed. We searched MEDLINE/PubMed. Biochemical recurrence at three and five years; incontinence rate (patients who used one pad or more) and erectile dysfunction rate at 12 and 36 months (patients who did not have sufficient erection to achieve sexual intercourse) were evaluated. The Mantel-Haenszel method was applied to estimate the pooled risk difference (RD) in the individual studies for categorical variables. All results were presented as 95% confidence intervals (95%CI). Random effects models were used regardless of the level of heterogeneity (I²). (PROSPERO CRD42022296998).
RESULTS
Eight studies comprising 2,677 men with prostate cancer were included. There was no difference in biochemical recurrence between ablative and radical treatments. We observed the same biochemical recurrence between ablative therapy and radical treatment within five years (19.3% vs. 16.8%, respectively; RD 0.07; 95%CI=-0.05, 0.19; I2=68.2%; P=0.08) and continence rate at 12 months (9.2% vs. 31.8%, respectively; RD -0.13; 95%CI, -0.27, 0.01; I2=89%; P=0.32). When focal treatment was analyzed alone, two studies with 582 patients found higher erectile function at 12 months in the ablative therapy group than in the radical treatment (88.9% vs. 30.8%, respectively; RD -0.45; 95%CI -0.84, -0.05; I2=93%; P=0.03).
CONCLUSION
Biochemical recurrence and urinary continence outcomes of ablative therapy and radical treatment were similar. Ablative therapy appears to have a high rate of sexual potency.

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.

AIMS
The association between heart failure (HF) patients and the incidence of cancer is not well understood, with conflicting results to date. The aim of this meta-analysis was to evaluate whether patients with HF have a higher risk of developing cancer.
METHODS AND RESULTS
We performed a systematic literature search using PubMed, Embase, and Scopus for relevant articles from inception until 10 December 2022. The primary clinical outcome was the incidence of cancer. Secondary endpoints were the incidence of breast cancer, lung cancer, haematological cancer, colorectal cancer, and prostate cancer. A total of 9 articles with 7 329 706 (515 041 HF vs. 6 814 665 non-HF) patients were involved in the analysis. The mean age of the patients in the HF and the non-HF groups was 69.06 and 66.76 years. The median follow-up duration was 6.7 years. The most common comorbidity among both groups includes diabetes mellitus (27.58 vs. 14.49%) and hypertension (81.46 vs. 57.38%). Patients with HF were associated with a significant increase in the incidence of cancer {hazard ratio [HR], 1.43 [95% confidence interval (CI): 1.21-1.68], < 0.001}, breast cancer [HR, 1.28 (95% CI: 1.09-1.50), < 0.001], lung cancer [HR, 1.89 (95% CI: 1.25-2.85), < 0.001], haematological cancer [HR, 1.63 (95% CI: 1.15-2.33), = 0.01], and colorectal cancer [HR, 1.32 (95% CI: 1.11-1.57), < 0.001] compared with patients without HF. However, the incidence of prostate cancer was comparable between both groups [HR, 0.97 (95% CI: 0.66-1.43), = 0.88].
CONCLUSION
This meta-analysis confirms that the state of HF is associated with a higher risk for incident cancer. These data may aid in raising awareness with physicians that cancer may develop in patients with prevalent heart failure and that early screening and evaluation may be useful in an early diagnosis of cancer.

Efficacy and safety of olaparib combined with abiraterone in patients with metastatic castration-resistant prostate cancer: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
Olaparib has been proven for the treatment of metastatic castration-resistant prostate cancer (mCRPC). This meta-analysis aims to comprehensively evaluate the efficacy and safety of the combination of olaparib and abiraterone in patients with mCRPC.
METHODS
The literature in PubMed, Embase, and Cochrane Library up until April 27, 2023, was systematically searched. In the studies included in this meta-analysis, olaparib combined with abiraterone was compared with abiraterone combined with placebo.
RESULTS
Two randomized controlled trials involving a total of 938 patients were included. Analysis indicated that olaparib combined with abiraterone significantly prolonged radiographic progression-free survival (rPFS: relative risk [RR] 0.66, 95% confidence interval [CI] 0.55-0.79), time to secondary progression or death (PFS2: hazard ratio [HR] 0.72, 95% CI 0.56-0.93), time to first subsequent therapy or death (TFST: HR 0.75, 95% CI 0.63-0.89), time to second subsequent therapy or death (TSST: HR 0.73, 95% CI 0.58-0.93), and confirmed prostate-specific antigen (PSA) response (RR 1.14, 95% CI 1.05-1.24). However, no statistically significant differences were found in the overall survival (OS: HR 0.87 95% CI 0.70-1.09), objective response rate (ORR: RR 0.97, 95% CI 0.70-1.33), and incidence of total adverse events (RR 1.07, 95% CI 0.94-1.22). A notable detail that the combination of olaparib and abiraterone was associated with an increased incidence of high-grade anemia (RR 7.47, 95% CI 1.36-40.88).
CONCLUSION
Olaparib combined with abiraterone is effective for patients with mCRPC. However, combination therapy has treatment-related adverse events compared with monotherapy, and this could be improved in future treatment management.

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 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.

Review
Since the release of the last meta-analysis on the association between fish intake and prostate cancer risk, several cohort studies have been published. Moreover, none of the previous meta-analyzes examined the dose-response association between fish intake and prostate cancer. Therefore, the current dose-response meta-analysis was conducted to summarize available findings on the associations of fish intake with the risk of prostate cancer in men. Online databases of PubMed, Scopus, and Web of Science were systematically searched up to September 2022. We included prospective cohort studies that examined the associations of fish intake with the risk of prostate cancer (total, localized, and advanced prostate cancer), its mortality, and cancer progression. Summary relative risks (RR) and 95% confidence intervals (CI) were calculated for the highest versus lowest categories of fish intake using random-effects models. Also, linear and non-linear dose-response analyzes were conducted. In total, 25 prospective cohort studies, recruiting 1,216,474 men, were included in the systematic review, and 22 studies were included in the meta-analysis. During the follow-up periods, ranging from 6 to 33 years, a total of 44,722 cases of prostate cancer were recorded. The comparison between the highest and lowest intakes of total fish revealed the summary RRs of 0.97 (95% CI: 0.86-1.10) for total, 1.01 (95% CI: 0.91-1.13) for advanced, and 0.90 (95% CI: 0.72-1.12) for localized prostate cancer, indicating no significant association. Moreover, the summary RR was 0.55 (95% CI: 0.33-0.92) for prostate cancer mortality and 0.84 (95% CI: 0.65-1.10) for prostate cancer progression, indicating an inverse association between fish intake and prostate cancer mortality. Also, in the dose-response analyzes, each 20 gram/day increase in total fish intake was associated with a 12% lower risk of prostate cancer mortality. Our findings support the protective association between total fish intake and the risk of prostate cancer mortality.

Review
BACKGROUND
Neuroendocrine prostate cancer (NEPC) is a rare neoplasm, and the role of both conventional imaging (CI) and positron emission tomography/computed tomography (PET/CT) for its assessment has not been clearly evaluated and demonstrated. The aim of this systematic review was to analyze the diagnostic performances of these imaging modalities in this setting.
METHODS
A wide literature search of the PubMed/MEDLINE, Scopus, and Web of Science databases was made to find relevant published articles about the role of CI and PET/CT for the evaluation of NEPC.
RESULTS
13 studies were included in the systematic review. PET/CT imaging with different radiopharmaceuticals has been evaluated in many studies (10) compared to CI (3 studies), which has only a limited role in NEPC. Focusing on PET/CT, a study used [F]FDG, labeled somatostatin analogs were used in 5 cases, a study used [Ga]Ga-FAPI-04, [Ga]Ga-PSMA-11 was evaluated in a single case, and two works used different tracers.
CONCLUSION
Published data on the role of PET/CT for the assessment of NEPC are limited. At present, it is still uncertain which tracer performs best, and although [F]FDG has been evaluated and seems to offer some advantages in availability and clinical staging, other tracers may be more useful to understand tumor biology or identify targets for subsequent radioligand therapy. Further research is therefore desirable. In contrast, data are still limited to draw a final conclusion on the role and the specific characteristics of CI in this rare form of neoplasm, and therefore, more studies are needed in this setting.
