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.

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.

Aims: Focal therapy treats individual areas of tumour in non-metastatic prostate cancer in patients unsuitable for active surveillance. The aim of this work was to evaluate the cost-effectiveness of focal therapy versus prostatectomy and external beam radiotherapy (EBRT).

Materials And Methods: A Markov cohort health state transition model with four health states (stable disease, local recurrence, metastatic disease and death) was created, evaluating costs and utilities over a 10-year time horizon for patients diagnosed with non-metastatic prostate cancer.

Prostate cancer is the most commonly diagnosed cancer in the United Kingdom. While androgen-deprivation therapy is the most common treatment for prostate cancer, patients undergoing this treatment typically experience side effects in terms of sleep disturbances. However, the relation between prostate cancer and sleep and the way in which sleep interventions may benefit oncological patients is underinvestigated in the literature.

Context: Whole-gland ablation is a feasible and effective minimally invasive treatment for localized prostate cancer (PCa). Previous systematic reviews supported evidence for favorable functional outcomes, but oncological outcomes were inconclusive owing to limited follow-up.

Objective: To evaluate the real-world data on the mid- to long-term oncological and functional outcomes of whole-gland cryoablation and high-intensity focused ultrasound (HIFU) in patients with clinically localized PCa, and to provide expert recommendations and commentary on these findings.

Objectives: To externally validate a published model predicting failure within 2 years after salvage focal ablation in men with localised radiorecurrent prostate cancer using a prospective, UK multicentre dataset.

Patients And Methods: Patients with biopsy-confirmed ≤T3bN0M0 cancer after previous external beam radiotherapy or brachytherapy were included from the FOcal RECurrent Assessment and Salvage Treatment (FORECAST) trial (NCT01883128; 2014-2018; six centres), and from the high-intensity focussed ultrasound (HIFU) Evaluation and Assessment of Treatment (HEAT) and International Cryotherapy Evaluation (ICE) UK-based registries (2006-2022; nine centres). Eligible patients underwent either salvage focal HIFU or cryotherapy, with the choice based predominantly on anatomical factors.

Purpose: In older patients who do not wish to undergo watchful waiting, focal therapy could be an alternative to the more morbid radical treatment. We evaluated the role of focal therapy in patients 70 years and older as an alternative management modality.

Materials And Methods: A total of 649 patients across 11 UK sites receiving focal high-intensity focused ultrasound or cryotherapy between June 2006 and July 2020 reported within the UK-based HEAT (HIFU Evaluation and Assessment of Treatment) and ICE (International Cryotherapy Evaluation) registries were evaluated.

Introduction: We aimed to test whether the current practice of using mpMRI stage might lead to a Will Rogers phenomenon with a stage migration compared to DRE in men undergoing radical prostatectomy.

Material And Methods: A total of 572 consecutive patients who underwent radical prostatectomy at a single institution (2007-2017) were included. Clinical stage using digital rectal examination was determined on table by the operating surgeon; mpMRI and pathological stage were recorded after tumor board review.

Video labelling is the assigning of meaningful information to raw videos. With the evolution of artificial intelligence and its intended incorporation into the operating room, video datasets can be invaluable tools for education and the training of intelligent surgical workflow systems through computer vision. However, the process of manual labelling of video datasets can prove costly and time-consuming for already busy practising surgeons.

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
  • Prostate cancer recurrences post-initial non-surgical treatment are mainly treated with androgen-deprivation therapy (ADT), but salvage radical prostatectomy (sRP) poses higher risks, prompting exploration of alternative treatments like salvage irreversible electroporation (sIRE).
  • A pilot study (SAFE) evaluated the safety and effectiveness of sIRE in 20 patients with localized recurrent prostate cancer after prior treatments, using advanced imaging and patient evaluations.
  • Initial findings suggest sIRE could be a viable and safer curative option for recurrent prostate cancer, with fewer side effects compared to traditional sRP approaches.
