Review
BACKGROUND
Prostate cancer is the most commonly diagnosed non-skin cancer in men. Screening for prostate cancer is widely accepted; however concerns regarding the harms outweighing the benefits of screening exist. Although patient's play a pivotal role in the decision making process, men may not be aware of the controversies regarding prostate cancer screening. Therefore we aimed to describe men's attitudes, beliefs and experiences of prostate cancer screening.
METHODS
Systematic review and thematic synthesis of qualitative studies on men's perspectives of prostate cancer screening. Electronic databases and reference lists were searched to October 2016.
FINDINGS
Sixty studies involving 3,029 men aged from 18-89 years, who had been screened for prostate cancer by Prostate Specific Antigen (PSA) or Digital Rectal Examination (DRE) and not screened, across eight countries were included. Five themes were identified: Social prompting (trusting professional opinion, motivation from family and friends, proximity and prominence of cancer); gaining decisional confidence (overcoming fears, survival imperative, peace of mind, mental preparation, prioritising wellbeing); preserving masculinity (bodily invasion, losing sexuality, threatening manhood, medical avoidance); avoiding the unknown and uncertainties (taboo of cancer-related death, lacking tangible cause, physiological and symptomatic obscurity, ambiguity of the procedure, confusing controversies); and prohibitive costs.
CONCLUSIONS
Men are willing to participate in prostate cancer screening to prevent cancer and gain reassurance about their health, particularly when supported or prompted by their social networks or healthcare providers. However, to do so they needed to mentally overcome fears of losing their masculinity and accept the intrusiveness of screening, the ambiguities about the necessity and the potential for substantial costs. Addressing the concerns and priorities of men may facilitate informed decisions about prostate cancer screening and improve patient satisfaction and outcomes.

OBJECTIVES
As part of the PIONEER Consortium objectives, we have explored which diagnostic and prognostic factors (DPFs) are available in relation to our previously defined clinician and patient-reported outcomes for prostate cancer (PCa).
DESIGN
We performed a systematic review to identify validated and non-validated studies.
DATA SOURCES
MEDLINE, Embase and the Cochrane Library were searched on 21 January 2020.
ELIGIBILITY CRITERIA
Only quantitative studies were included. Single studies with fewer than 50 participants, published before 2014 and looking at outcomes which are not prioritised in the PIONEER core outcome set were excluded.
DATA EXTRACTION AND SYNTHESIS
After initial screening, we extracted data following the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of prognostic factor studies (CHARMS-PF) criteria and discussed the identified factors with a multidisciplinary expert group. The quality of the included papers was scored for applicability and risk of bias using validated tools such as PROBAST, Quality in Prognostic Studies and Quality Assessment of Diagnostic Accuracy Studies 2.
RESULTS
The search identified 6604 studies, from which 489 DPFs were included. Sixty-four of those were internally or externally validated. However, only three studies on diagnostic and seven studies on prognostic factors had a low risk of bias and a low risk concerning applicability.
CONCLUSION
Most of the DPFs identified require additional evaluation and validation in properly designed studies before they can be recommended for use in clinical practice. The PIONEER online search tool for DPFs for PCa will enable researchers to understand the quality of the current research and help them design future studies.

Review
OBJECTIVE
Considering the importance of screening for prostate cancer, the possibility of damage resulting from indiscriminate screening and the difficulty of disclosure and adherence to the main guidelines on the subject, we aimed to identify current guidelines, look for common approaches and establish a core of conducts.
METHOD
Systematic review of the literature on screening practice guidelines for prostate cancer searching the databases PubMed, Lilacs and Google Scholar and active search in the sites of several national health entities.
RESULTS
Twelve (12) guidelines were selected, whose analysis resulted in the identification of six common points of conduct, with the following minimum core of recommendations: (1) screening indication or not: must be individualized, and preceded by an informed decision; (2) tests used: PSA with or without rectal digital examination; (3) age at which initiate testing in men in general risk: 50-55 years; (4) age at which to initiate testing in men at increased risk: 40-45 years; (5) the interval between screening: annual or biennial; and (6) age at which to discontinue testing: 70 years-old or life expectancy less than 10 years.
CONCLUSION
Although there are differences between them, it was possible to establish a minimum core of conducts that may be useful in the daily practice of the physician.

Review
OBJECTIVE
To systematically review the literature and provide an update and integration of existing peer-reviewed guidelines with recent systematic reviews and with primary studies related to the early recognition and management of prostate cancer in primary care.
DATA SOURCES
We searched MEDLINE and EMBASE for relevant articles. The quality of the evidence to support existing guideline recommendations and the consistency of recommendations with updated evidence were assessed. Applicability in a Canadian primary care setting was also evaluated.
STUDY SELECTION
All studies conducted in the primary care setting that provided information on clinical features predictive of prostate cancer were included. Also, studies that assessed the accuracy of nomograms to predict prostate cancer were reviewed.
SYNTHESIS
The findings suggest that lower urinary tract symptoms are not highly predictive of prostate cancer. However, evidence suggests that FPs might be good at discriminating between patients with and without prostate cancer using digital rectal examination and prostate-specific antigen testing. Nomograms might also be useful in assessing patients for aggressive prostate cancers.
CONCLUSION
The results of this review can be used to inform recommendations for referral for suspected prostate cancer in the primary care setting. They could also inform development of prostate cancer diagnostic assessment programs.

Review
BACKGROUND
Prostate cancer (PC) is the most commonly diagnosed non-cutaneous cancer in men and their second or third leading cause of cancer death. Prostate-specific antigen (PSA) testing for PC has been in common practice for more than 20 years.
OBJECTIVES
A systematic review of the scientific literature was conducted to determine the effectiveness of PSA-based population screening programs for PC to inform policy decisions in a publicly funded health care system.
DATA SOURCES
A systematic review of bibliographic databases was performed for systematic reviews or randomized controlled trials (RCT) of PSA-based population screening programs for PC.
REVIEW METHODS
A broad search strategy was employed to identify studies reporting on key outcomes of PC mortality and all-cause mortality.
RESULTS
The search identified 5 systematic reviews and 6 RCTs. None of the systematic reviews found a statistically significant reduction in relative risk (RR) of PC mortality or overall mortality with PSA-based screening. PC mortality reductions were found to vary by country, by screening program, and by age of men at study entry. The European Randomized Study of Screening for Prostate Cancer found a statistically significant reduction in RR in PC mortality at 11-year follow-up (0.79; 95% CI, 0.67-0.92), although the absolute risk reduction was small (1.0/10,000 person-years). However, the primary treatment for PCs differed significantly between countries and between trial arms. The American Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) found a statistically non-significant increase in RR for PC mortality with 13-year follow-up (1.09; 95% CI, 0.87-1.36). The degree of opportunistic screening in the control arm of the PLCO trial, however, was high. None of the RCTs found a reduction in all-cause mortality and all found a statistically significant increase in the detection of mainly low-risk, organ-confined PCs in the screening arm.
CONCLUSIONS
There was no evidence of a PC mortality reduction in the American PLCO trial, which investigated a screening program in a setting where opportunistic screening was already common practice. Given that opportunistic PSA screening practices in Canada are similar, it is unlikely that the introduction of a formal PSA screening program would reduce PC mortality.

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 Review
INTRODUCTION
econd-generation androgen receptor inhibitors (SGARIs), namely enzalutamide, apalutamide, and darolutamide, are good for improving survival outcomes in prostate cancer patients, but some researchers have shown that using SGARIs increases side effects, which complicates clinicians' choice of. Therefore, we performed this network meta-analysis to assess the efficacy and toxicity of several SGARIs in the treatment of patients with metastatic hormone-sensitive prostate cancer (mHSPC), non-metastatic castration-resistant prostate cancer (nmCRPC), and metastatic castration-resistant prostate cancer (mCRPC).
METHODS
We searched PubMed, EMBASE and Cochrane Library databases from January 2000 to December 2022 to identify randomized controlled studies associated with SGARIs. We use Stata 16.0 and R 4.4.2 for data analysis, hazard ratio (HR) with 95% confidence intervals (CI) were used to assess the results.
RESULTS
This meta-analysis included 7 studies with a total of 9488 patients. In mHSPC, enzalutamide and darolutamide had a positive effect on overall survival (OS) (HR, 0.70; 95% CI, 0.59-0.82), but we did not find a difference in their efficacy to improve OS (HR, 1.19; 95% CI, 0.75-1.89). Also in nmCRPC, enzalutamide, apalutamide and darolutamide were beneficial for metastasis-free survival (MFS) (HR, 0.32; 95% CI, 0.25-0.41). Compared to darolutamide, enzalutamide (HR, 0.71; 95% CI, 0.54-0.93) and apalutamide (HR, 0.68; 95% CI, 0.51-0.91) prolonged MFS, but there was no difference in efficacy between enzalutamide and apalutamide (HR, 0.97; 95% CI, 0.73-1.28). Finally in mCRPC, there was no significant difference in indirect effects on OS between pre- and post-chemotherapy enzalutamide (HR, 0.89; 95% CI, 0.70-1.13). However, using enzalutamide before chemotherapy to improve radiographic progression-free survival (rPFS) was a better option (HR, 2.11; 95% CI, 1.62-2.73).
CONCLUSION
The SGARIs used in each trial were beneficial for the primary endpoint in the study. Firstly there was no significant difference in the effect of enzalutamide and darolutamide in improving OS in patients with mHSPC. Secondly improving MFS in patients with nmCRPC was best achieved with enzalutamide and apalutamide. In addition both pre- and post-chemotherapy use of enzalutamide was beneficial for OS in mCRPC patients, but for improving rPFS pre-chemotherapy use of enzalutamide should be preferred.The INPLASY registration number of this systematic review is INPLASY202310084.

Review
OBJECTIVE
This systematic review (PROSPERO ID: CRD42022226375) aimed to identify the eHealth literacy of men with prostate cancer, and their caregivers.
METHODS
8 databases (MEDLINE, SCOPUS, EMBASE, Web Of Science, PsycINFO, ERIC, CINAHL, Cochrane CENTRAL) and grey literature sources (e.g. Google Scholar) were searched from inception to December 2023. Articles were included if assessing eHealth/digital literacy of men with prostate cancer, or their carers', and health outcome associations. Formats such as case reports, and review papers were excluded. Records and full texts underwent independent screening and data extraction. Author disagreements were resolved by discussion. The Mixed Methods Appraisal Tool (MMAT) was used to appraise included literature, with narrative synthesis of results.
RESULTS
21,581 records were retrieved, with 7 articles satisfying inclusion criteria. A heterogenous field was characterised with lack of modern eHealth literacy measurement tools identified. Results suggest novice eHealth literacy using web 1.0 technologies. Non-validated measures of literacy demonstrate mixed results, while health outcome effects limited in scope and reliability.
CONCLUSION
Prostate cancer survivors' eHealth literacy levels is likely novice, and requires further investigation.
PRACTICE IMPLICATIONS
Digital technologies/resources implemented as part of patient communication practices should be vetted for quality, and tailored to patients' eHealth literacy abilities and/or needs.

Review
Prostate specific membrane antigen (PSMA) has been the subject of several studies in recent decades as a promising molecular target for prostate cancer (PCa), in fact it is considered an excellent molecular target for both PCa imaging (both for staging and follow-up), by means of PET/CT and for radioligand therapy. Its interesting molecular features have enabled the development of a new diagnostic and therapeutic approach for PCa, called "theranostics." Considering the abundance of PSMA-based probes that have appeared so far in the literature, the present work focuses the attention on radiopharmaceuticals with increasing clinical application, highlighting advantages and disadvantages in terms of different metabolization and excretion processes, pharmacokinetic, binding affinity and variable internalization rate, tumor-to-background ratio, residence times and toxicity profile.

Review
BACKGROUND
Prostate cancer is highly prevalent and impacts profoundly on patients' quality of life, leading to a range of supportive care needs.
METHODS
An updated systematic review and thematic synthesis of qualitative data using the Preferred Reporting Items for Systematic Reviews (PRISMA) reporting guidelines, to explore prostate cancer patients' experience of, and need for, supportive care. Five databases (Medline, Embase, PsycInfo, Emcare and ASSIA) were searched; extracted data were synthesised using Corbin and Strauss's 'Three Lines of Work' framework.
RESULTS
Searches identified 2091 citations, of which 105 were included. Overarching themes emerged under the headings of illness, everyday life and biographical work. Illness work needs include consistency and continuity of information, tailored to ethnicity, age and sexual orientation. Biographical work focused on a desire to preserve identity in the context of damaging sexual side effects. Everyday life needs centred around exercise and diet support and supportive relationships with partners and peers. Work-related issues were highlighted specifically by younger patients, whereas gay and bisexual men emphasised a lack of specialised support.
CONCLUSION
While demonstrating some overarching needs common to most patients with prostate cancer, this review offers novel insight into the unique experiences and needs of men of different demographic backgrounds, which will enable clinicians to deliver individually tailored supportive care.
