Background/Objectives: Pathological factors are integral in the risk stratification and management of localized prostate cancer. In recent years, there has been an upsurge of studies that uncovered novel approaches and have refined prognostic factors for prostate cancer in needle biopsy and radical prostatectomy (RP) specimens. Methods: We conducted a review of literature and summarized the significant recent updates on pathological factors for localized prostate cancer. Results: Innovative factors derived from the traditional Gleason grading, such as the extent of Gleason pattern 4 and presence of cribriform pattern are now recognized to significantly improve discrimination of outcome. The components and rules of Gleason grading themselves underwent modifications, and the subsequent prognostic grouping of the different grades (Grade group) have resulted in enhanced stratification of behavior more meaningful in management decision. The approaches for grade reporting in systematic or targeted needle biopsies and in RP with multifocal cancers are also being optimized. Newer tumor growth pattern-based factors such as intraductal carcinoma and atypical intraductal proliferation can have ramifications in management, especially in the background of low to intermediate risk prostate cancers. Gleason grade considerations in the different post-treatment settings and for de novo and residual prostate cancers with varying treatment effects have also been explicated. Likewise, the application of more traditional factors in tumor extent and perineural invasion in biopsy, or positive surgical margin in RP, have also evolved. Conclusions: Some of these newer pathological factors are now officially recommended in standardized pathology reporting protocols and are applied in the management decision for localized prostate cancer.

Background/Objectives: Primary prevention, germline, familial, or other pre- or post-diagnostic and standard treatment-elevated progression or recurrence risk and mitigating adverse events from systemic treatment are all clinical opportunities to reduce the risk of lethal prostate cancer. This review attempted to provide a practical and realistic consensus via an international committee of experts who, in general, harbor career-long experience in this discipline. Methods: A PubMed review primarily utilizing the latest meta-analyses, systematic reviews, and methodologically robust epidemiologic recent data adjusting for multiple confounding variables was conducted. The goal of this committee was to highlight tangible options for clinicians and patients. Results: Behavioral patterns and metrics known to reduce cardiovascular morbidity, mortality, and all-cause mortality (premature death) appear to prevent numerous lethal common cancers, including prostate cancer. This practical approach allows for the greatest probability of patient success since cardiovascular disease (CVD) is the primary cause of death in men with and without prostate cancer, and a notable source of morbidity and mortality in men with advanced disease due to systemic conventional treatment as well as the inflammatory contribution of cancer itself. Heart-healthy dietary patterns, exercise, healthy weight/waist circumference, eliminating tobacco, minimizing alcohol exposure, and other behaviors to reduce the risk of CVD should be prioritized. CVD-preventive medications, including aspirin, GLP-1 agonists, metformin, statins, etc., should receive attention to improve compliance for those that already qualify for these agents and to increase the probability of enhancing the quality and quantity of life. Dietary supplements do not have favorable data currently to espouse their utilization to prevent lethal prostate cancer but may have an ancillary role in mitigating some adverse effects of treatment. Conclusions: Remarkably, heart-healthy lifestyle changes, metrics, and promising repurposed medications known to reduce cardiovascular events, promote longevity, and improve mental health could simultaneously prevent lethal prostate cancer. This serendipitous association provides clinicians and their patients a higher probability of success, regardless of their prostate cancer pathway or circumstance. Full article

Background/Objectives: The diagnostic approach to prostate cancer (PCa) has evolved from systematic biopsies to imaging-guided strategies that improve detection of clinically significant PCa (csPCa) while reducing overdiagnosis. Multiparametric magnetic resonance imaging (mpMRI) has emerged as the gold standard for pre-biopsy evaluation, while micro-ultrasound (MicroUS) offers a promising alternative with real-time imaging capabilities. Methods: We examined the principles, image interpretation frameworks (Prostate Imaging Reporting and Data System (PI-RADS) and Prostate Risk Identification using Micro UltraSound (PRI-MUS)), and clinical applications of mpMRI and MicroUS, comparing their diagnostic accuracy in biopsy-naïve patients, repeat biopsy scenarios, active surveillance, and staging. Results: mpMRI improves csPCa detection, reduces unnecessary biopsies, and enhances risk stratification. Landmark studies such as PRECISION (Prostate Evaluation for Clinically Important Disease: Sampling Using Image Guidance or Not?) and PRIME (Prostate Imaging Using MRI±Contrast Enhancement) confirm its superiority over systematic biopsy. However, mpMRI remains resource-intensive, with limitations in accessibility and interpretation variability. Conversely, MicroUS, with its high-resolution real-time imaging, shows non-inferiority to mpMRI and potential advantages in magnetic resonance imaging (MRI)-ineligible patients. It improves lesion visualization and biopsy targeting, with ongoing trials such as OPTIMUM (Optimization of prostate biopsy—Micro-Ultrasound versus MRI) evaluating its standalone efficacy. Conclusions: mpMRI and MicroUS are complementary modalities in PCa diagnosis. While mpMRI remains the preferred imaging standard, MicroUS offers an alternative, particularly in patients with MRI contraindications. Combining these techniques could enhance diagnostic accuracy, reduce unnecessary interventions, and refine active surveillance strategies. Future research should focus on integrating both modalities into standardized diagnostic pathways for a more individualized approach. Full article

Background/Objectives: Focal therapy (FT) and technology are closely connected. Advanced imaging allows for precise identification of the index lesion, enabling the targeted use of various thermal and non-thermal energy sources through different approaches, with specific techniques tailored to lesion location and operator expertise. This personalized approach enhances both safety and effectiveness, facilitating customized treatment planning. Methods: The International Consultation on Urological Diseases formed a committee to review the current literature on FT for prostate cancer (PCa), focusing specifically on the technique. Following in-depth discussions, the committee chose a “by lesion” approach rather than the traditional “by energy” approach to structure the review. A comprehensive PubMed search was conducted to gather relevant articles on the various energy modalities and procedural approaches used in FT for PCa. Results: Lesions in the apex, anterior, and posterior regions of the prostate can be accessed through several FT approaches, each associated with specific energy modalities and techniques. The transrectal approach utilizes high-intensity focused ultrasound (HIFU) and focal laser ablation (FLA), while the transperineal approach is compatible with energy sources such as cryotherapy, irreversible electroporation (IRE), brachytherapy, and FLA. The transurethral approach supports methods such as transurethral ultrasound ablation (TULSA). Each approach offers distinct advantages based on lesion location, treatment area, and energy modality. The choice of technique evaluated the safety and efficacy of each energy source and approach based on specific treatment areas within the prostate, highlighting the need for robust research across lesion locations and modalities, rather than focusing solely on each modality for a specific region. Conclusions: FT is rapidly advancing with new energy sources, technological improvements, and increasing operator expertise. To further optimize FT, research should prioritize evaluating the safety and effectiveness of different energy sources for various lesion locations, focusing on the treatment area rather than the energy modality itself.

Background/Objectives: Pelvic lymph node dissection during radical cystectomy has been established to be important for staging and therapeutic purposes. However, there is uncertainty regarding the optimal extent of nodal dissection. This study aimed to assess the impact of an extended pelvic lymphadenectomy template compared to a standard template in patients with bladder cancer undergoing radical cystectomy. Methods: We performed a systematic review and meta-analysis of randomised studies comparing extended pelvic lymph node dissection to standard pelvic lymph node dissection in patients undergoing radical cystectomy. A search of multiple databases was performed up to October 2024. The standard template was defined as including at least the obturator and internal and external iliac nodes. An extended template was defined as a standard template plus the removal of proximal nodal packets. The primary outcomes were overall survival and major Clavien–Dindo complications. Results: Two studies encompassing a total of 933 participants met the eligibility criteria. There was no observed improvement in overall survival with extended lymph node dissection compared to limited dissection [HR 0.95, 95%CI 0.66–1.4]. In addition, extended lymph node dissection was associated with an increased risk of grade ≥3 Clavien–Dindo complications compared to limited nodal dissection [RR 1.2, 95%CI 1.02–1.37]. There was also an increased risk of lymphoceles requiring intervention with extended lymphadenectomy. Conclusions: Extended pelvic lymphadenectomy does not improve oncological outcomes and is associated with increased morbidity compared to a standard template in bladder cancer patients undergoing radical cystectomy.

Background/Objectives: Randomised trials show that screening with prostate-specific antigen (PSA) and systematic prostate biopsies can reduce prostate cancer mortality but leads to high rates of overdiagnosis. Today, improved diagnostic methods more selectively detect potentially lethal, high-grade prostate cancer. Methods: This is a narrative review of modern diagnostic methods, ongoing trials, national policies and knowledge gaps related to screening and early detection of prostate cancer. Results: Screening intervals can be prolonged in men with PSA values below around 1 ng/mL as these men are at very low long-term risk of prostate cancer death. Overdiagnosis can be reduced by magnetic resonance imaging (MRI) and lesion-targeted prostate biopsies. Risk calculators and ancillary biomarkers can select men for further investigation and thereby reduce resource needs. These new methods are evaluated in large, randomised screening trials. The remaining knowledge gaps include optimal PSA cut-offs, screening intervals, start and stop ages, and the long-term balance between benefits and harm. Until recently, almost no national healthcare authority recommended population-based screening for prostate cancer. Now, the European Union Council recommends an evaluation of the feasibility of organised, risk-stratified screening. This has led to several pilot projects. In some other parts of the world, such as sub-Saharan Africa and the Caribbean, such initiatives are lacking despite high prostate cancer mortality rates. Conclusions: Risk-stratified prostate cancer screening including MRI and targeted biopsy reduces overdiagnosis. Results from ongoing research are needed to optimise screening protocols and to define long-term benefits and harms. Initiatives for early detection and screening are emerging across the world but are still lacking in many countries with high prostate cancer mortality. Full article
