Article Synopsis
  • Radical prostatectomy (RP) is a key surgical treatment for prostate cancer, but assessing surgical margins during the procedure is difficult and costly, making fluorescence confocal microscopy (FCM) a potential solution.
  • The IP8-FLUORESCE study is a multicentre, prospective study that investigates the accuracy of digital FCM in identifying prostate cancer at surgical margins, comparing it to traditional histopathology methods.
  • The study will involve 153 patients undergoing robot-assisted RP, using FCM on prostate specimens immediately after surgery, with results evaluated by blinded uro-pathologists for accuracy in detecting cancer presence at the margins.

Background And Objective: Cytoreductive treatments for patients diagnosed with de novo synchronous metastatic hormone-sensitive prostate cancer (mHSPC) confer incremental survival benefits over systemic therapy, but these may lead to added toxicity and morbidity. Our objective was to determine patients' preferences for, and trade-offs between, additional cytoreductive prostate and metastasis-directed interventions.

Methods: A prospective multicentre discrete choice experiment trial was conducted at 30 hospitals in the UK between December 3, 2020 and January 25, 2023 (NCT04590976).

For men with prostate cancer who develop biochemical failure after radiotherapy, European guidelines recommend reimaging with Ga-PSMA-11 PET/CT and multiparametric MRI (mpMRI). However, the accuracy of Ga-PSMA-11 PET/CT for detecting intraprostatic recurrences is unclear, both with and without mpMRI. A single-center retrospective study of a series of patients investigated for radiorecurrence between 2016 and 2022 is described.

Article Synopsis
  • The study aimed to compare biopsy recommendation rates and accuracy between the Prostate Imaging-Reporting and Data System version 2 (PI-RADSv2) and the Likert scale for detecting significant and insignificant prostate cancer in men aged 50-69 participating in the IP1-PROSTAGRAM trial.
  • Men were screened using Prostagram MRI, and results showed that more patients were recommended for biopsy with the Likert scale compared to PI-RADSv2 when the MRI score was ≥3, though accuracy in detecting cancer was similar for both systems.
  • The findings indicate that while the Likert scale may suggest more biopsy recommendations, both methods have comparable effectiveness in identifying clinically significant prostate cancer.

Background: Prostate cancer (PCa) has a high lifetime prevalence (one out of six men), but currently there is no widely accepted screening programme. Widely used prostate specific antigen (PSA) test at cut-off of 3.0 ng/mL does not have sufficient accuracy for detection of any prostate cancer, resulting in numerous unnecessary prostate biopsies in men with benign disease and false reassurance in some men with PCa.

Article Synopsis
  • The RAPID diagnostic pathway aims to improve efficiency in prostate imaging and diagnosis while reducing patient burden through better standardization of procedures.
  • A study involving 2130 patients revealed that 43% could avoid biopsy, with significant variations in biopsy avoidance rates across different sites.
  • The pathway also reduced the time to diagnosis from 32.1 days in the pre-RAPID cohort to 15.9 days, with similar cancer detection rates regardless of anesthesia used during transperineal targeted biopsy.

Background: Although multiparametric magnetic resonance imaging (MRI) has high sensitivity, its lower specificity leads to a high prevalence of false-positive lesions requiring biopsy.

Objective: To develop and externally validate a scoring system for MRI-detected Prostate Imaging Reporting and Data System (PIRADS)/Likert ≥3 lesions containing clinically significant prostate cancer (csPCa).

Design, Setting, And Participants: The multicentre Rapid Access to Prostate Imaging and Diagnosis (RAPID) pathway included 1189 patients referred to urology due to elevated age-specific prostate-specific antigen (PSA) and/or abnormal digital rectal examination (DRE); April 27, 2017 to October 25, 2019.

Article Synopsis
  • Advances in systemic agents for metastatic prostate cancer have improved overall survival, leading to a need for better understanding patients' values and preferences for treatment.
  • A systematic review was conducted across 15 studies with 1491 participants to assess patients' preferences regarding treatment options, highlighting treatment effectiveness and symptom delay as top priorities.
  • The findings suggest that patients are willing to accept some treatment-related side effects in exchange for potential benefits, while concerns about cancer progression, pain, and fatigue emerged as important themes from qualitative studies.

Introduction: Systemic therapy with androgen deprivation therapy (ADT) and intensification with agents such as docetaxel, abiraterone acetate and enzalutamide has resulted in improved overall survival in men with synchronous metastatic hormone-sensitive prostate cancer (mHSPC). Novel local cytoreductive treatments and metastasis-directed therapy are now being evaluated. Such interventions may provide added survival benefit or delay the requirement for further systemic agents and associated toxicity but can confer additional harm.

Retrograde ureteric calculus migration is a rare phenomenon. Herein, we report two such cases where each patient presented with a calculus, measured at 5 mm and 6 mm, respectively, at the vesicoureteric junction (VUJ) on noncontrast computerized tomography kidneys, ureters, and bladder (CTKUB). Following acute presentation with renal colic, each patient opted for conservative management of their ureteric stone and became asymptomatic when undergoing their follow-up imaging.

Introduction: Survival in men diagnosed with synchronous metastatic prostate cancer has increased following the use of upfront systemic treatment, using chemotherapy and other novel androgen receptor targeted agents, in addition to standard androgen deprivation therapy (ADT). Local cytoreductive and metastasis-directed interventions are hypothesised to confer additional survival benefit. In this setting, IP2-ATLANTA will explore progression-free survival (PFS) outcomes with the addition of sequential multimodal local and metastasis-directed treatments compared with standard care alone.

Purpose: We compared clinically significant prostate cancer detection by visual estimation and image fusion targeted transperineal prostate biopsy.

Materials And Methods: This multicenter study included patients with multiparametric magnetic resonance imaging lesions undergoing visual estimation or image fusion targeted transperineal biopsy (April 2017-March 2020). Propensity score matching was performed using demographics (age and ethnicity), clinical features (prostate specific antigen, prostate volume, prostate specific antigen density and digital rectal examination), multiparametric magnetic resonance imaging variables (number of lesions, PI-RADS® score, index lesion diameter, whether the lesion was diffuse and radiological T stage) and biopsy factors (number of cores, operator experience and anesthetic type).

Although radiotherapy to the prostate for cancer is effective, recurrence occurs in 10-15% within 5 years. Traditional salvage treatments for men with radiorecurrent prostate cancer comprise of watchful waiting (WW) with or without androgen deprivation therapy (ADT) or radical prostatectomy (RP). Neither strategy provides ideal therapeutic ratios.

Knowing the demerits of the transrectal ultrasound guided biopsy has led to a shift in the general techniques and technology of the prostate biopsy. In addition, the advances in magnetic resonance imaging (MRI) sensitivity and the evidence from the PROMIS trial about its ability to detect clinically significant tumours encourage urologists and industry to implement MRI-guided targeted biopsy. However, the science is still looking how to improve safety and increase its cancer detection rate (CDR).
