Although digital rectal examination (DRE) is recommended in combination with prostate-specific antigen (PSA) for detection of prostate cancer (PCa), there are limited data to support its use as a screening/early detection test. Our objective was to assess the diagnostic value of DRE in screening for early detection of PCa. In August 2023, we queried the PubMed, Scopus, and Web of Science databases to identify prospective studies simultaneously investigating the diagnostic performance of DRE and PSA for PCa screening. The primary endpoints were the positive predictive value (PPV) and cancer detection rate (CDR) of DRE. Secondary endpoints included the PPV and CDR of both PSA alone and in combination with DRE. We conducted meta-regression analysis to compare the CDR and PPV of different screening strategies. This meta-analysis is registered on PROSPERO (CRD42023446940). We identified eight studies involving 85,798 participants, of which three were randomized controlled trials and five were prospective diagnostic studies, that reported the PPV and CDR of both DRE and PSA for the same cohort. Our analysis revealed a pooled PPV of 0.21 (95% confidence interval [CI] 0.13-0.33) for DRE, which is similar to the PPV of PSA (0.22, 95% CI 0.15-0.30; p = 0.9), with no benefit from combining DRE and PSA (PPV 0.19, 95% CI 0.13-0.26; p = 0.5). However, the CDR of DRE (0.01, 95% CI: 0.01-0.02) was significantly lower than that of PSA (0.03, 95% CI 0.02-0.03; p < 0.05) and the combination of DRE and PSA (0.03, 95% CI 0.02-0.04; p < 0.05). The screening strategy combining DRE and PSA was not different to that of PSA alone in terms of CDR (p = 0.5) and PPV (p = 0.5). Our comprehensive review and meta-analysis indicates that both as an independent test and as a supplementary measure to PSA for PCa detection, DRE exhibits a notably low diagnostic value. The collective findings from the included studies suggest that, in the absence of clinical symptoms and signs, DRE could be potentially omitted from PCa screening and early detection strategies. Our review shows that the screening performance of digital rectal examination for detection of prostate cancer is not particularly impressive, suggesting that it might not be necessary to conduct this examination routinely.

Background: Androgen-receptor pathway inhibitors (ARPIs) have dramatically changed the management of advanced/metastatic prostate cancer (PCa). However, their cardiovascular toxicity remains to be clarified. Objective: To analyze and compare the risks of cardiovascular events secondary to treatment of PCa patients with different ARPIs. Methods: In August 2023, we queried PubMed, Scopus, and Web of Science databases to identify randomized controlled studies (RCTs) that analyze PCa patients treated with abiraterone, apalutamide, darolutamide, and enzalutamide. The primary outcomes of interest were the incidence of cardiac disorder, heart failure, ischemic heart disease (IHD), atrial fibrillation (AF), and hypertension. Network meta-analyses (NMAs) were conducted to compare the differential outcomes of each ARPI plus androgen deprivation therapy (ADT) compared to standard of care (SOC). Results: Overall, 26 RCTs were included. ARPIs were associated with an increased risk of cardiac disorders (RR: 1.74, 95% CI: 1.13–2.68, p = 0.01), heart failure (RR: 2.49, 95% CI: 1.05–5.91, p = 0.04), AF (RR: 2.15, 95% CI: 1.14–4.07, p = 0.02), and hypertension (RR: 2.06, 95% CI: 1.67–2.54, p < 0.01) at grade ≥3. Based on NMAs, abiraterone increased the risk of grade ≥3 cardiac disorder (RR:2.40, 95% CI: 1.42–4.06) and hypertension (RR:2.19, 95% CI: 1.77–2.70). Enzalutamide was associated with the increase of grade ≥3 AF(RR: 3.17, 95% CI: 1.05–9.58) and hypertension (RR:2.30, 95% CI: 1.82–2.92). Conclusions: The addition of ARPIs to ADT increases the risk of cardiac disorders, including IHD and AF, as well as hypertension. Each ARPI exhibits a distinct cardiovascular event profile. Selecting patients carefully and vigilant monitoring for cardiovascular issues is imperative for those undergoing ARPI + ADT treatment.

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.

(1) Background: Intravesical chemotherapy is the standard of care in intermediate-risk non-muscleinvasive bladder cancer (NMIBC). Different agents are used across the world based on availability, cost, and practice patterns. Epirubicin (EPI), one of these agents, has been used by many centers over many decades. However, its true differential efficacy compared to other agents and its tolerability are still poorly reported. We aimed to assess the differential efficacy and safety of intravesical EPI in NMIBC patients. (2) Methods: This study aimed to systematically review the efficacy and safety profile of Epirubicin (EPI) in the management of non-muscle invasive bladder cancer (NMIBC) compared to other adjuvant therapies. A systematic search of the PUBMED, Web of Science, clinicaltrials.gov, and Google Scholar databases was conducted on 31 December 2023, using relevant terms related to EPI, bladder cancer, and NMIBC. The inclusion criteria targeted studies that evaluated patients treated with EPI following the transurethral resection of bladder tumors (TURBT) for NMIBC and compared oncological outcomes such as recurrence and progression with other adjuvant therapies, including Mitomycin C (MMC), Gemcitabine (GEM), and Bacillus Calmette-Guérin (BCG). Additionally, studies investigating the safety profile of EPI administered intravesically at room temperature and under hyperthermia, as well as oncological outcomes associated with hyperthermic intravesical EPI administration, were included. (3) Results: Eleven studies reported adverse events after adjuvant intravesical instillations with EPI; the most frequently reported adverse events included cystitis (34%), dysuria, pollakiuria, hematuria, bladder irritation/spasms, fever, nausea and vomiting, and generalized skin rash (2.3%). Nine studies compared EPI to BCG in terms of recurrence and progression rates; BCG instillations showed a lower recurrence rate compared to EPI, with limited or non-significant differences in progression rates. Two studies found no significant differences between EPI and MMC regarding progression and recurrence rates. One study showed statistically significant lower recurrence and progression rates with GEM in high-risk NMIBC patients. Another study found no significant differences between EPI and GEM regarding recurrence and progression. (4) Conclusions: EPI exhibits similar oncological performances to Gemcitabine and Mitomycin C currently used for adjuvant therapy in NMIBC. Novel delivery mechanisms such as hyperthermia are interesting newcomers.

Context: Active surveillance (AS) is a standard of care for patients with low -risk and selected intermediate -risk prostate cancer (PCa). Nevertheless, there is a lack of summary evidence on how to impact disease trajectory during AS. Objective: To assess which interventions prevent PCa progression effectively during AS. Evidence acquisition: We queried PubMed, Scopus, and Web of Science databases to identify studies examining the impact of interventions aimed at slowing disease progression during AS. The primary endpoint was PCa progression, the definition of which must have included pathological upgrading. The secondary endpoint included treatment toxicities. Evidence synthesis: We identified 22 studies, six randomized controlled trials and 16 observational studies, which analyzed the association between different interventions and PCa progression during AS. The interventions considered in the studies included 5 -alpha reductase inhibitors (5-ARIs), statins, diet, exercise, chlormadinone, fexapotide triflutate (FT), enzalutamide, coffee, vitamin D3, and PROSTVAC. We found that administration of 5-ARIs was associated with improved progression -free survival (PFS; hazard ratio: 0.59; 95% confidence interval 0.48-0.72), with no increased toxicity signals. Therapies such as vitamin D3, chlormadinone, FT, and enzalutamide have shown some efficacy. However, these anticancer drugs have been associated with treatment -related adverse events in up to 88% of patients. Conclusions: The use of 5-ARIs in PCa patients on AS is associated with longer PFS. However, for the other interventions, it is difficult to draw clear conclusions based on the weak available evidence. Patient summary: Patients with prostate cancer managed with active surveillance (AS) who are treated with 5 -alpha reductase inhibitors have a lower risk of disease progression, with minimal adverse events. Other interventions require more studies to determine their efficacy and safety profile in men on AS. (c) 2023 The Author(s). Published by Elsevier B.V. on behalf of European Association of Urology.
