Dosimetry, Toxicity and Stability Associated With a Hyaluronic Acid‐Based Prostate‐Rectal Spacing Device During Prostate Radiation Therapy: A Retrospective Comparative Analysis

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Rectal spacers composed of stabilised hyaluronic acid facilitated a favourable toxicity profile compared to no spacing during prostate radiation therapy. Acute GI toxicity (grade ≥ 1) was lower in the spacer cohort (23.5% vs. 48.0%; odds ratio = 0.33, p = 0.05) with grade ≥ 2 toxicity substantially lower (2.9% vs. 20.0%).

A fusion system of transrectal ultrasound with magnetic resonance imaging in guidance of prostate cancer biopsy

open access: yes肿瘤影像学, 2016
Transrectal ultrasound (TRUS) in the guidance of prostate cancer biopsy is the definite method, however, some limitations still exist, such as high number of biopsy cores, low sensitivity and so on. Many researchers continue to find new technical methods

Preimplant factors affecting postimplant CT-determined prostate volume and the CT/TRUS volume ratio after transperineal interstitial prostate brachytherapy with 125I free seeds

open access: yesRadiation Oncology, 2010
Background The aim was to identify preimplant factors affecting postimplant prostate volume and the increase in prostate volume after transperineal interstitial prostate brachytherapy with 125I free seeds.

A two‐stage model for precise identification and Gleason grading of clinically significant prostate cancer: a hybrid approach

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 93-105, March 2025.
This study developed a two‐stage model using radiomics‐based multiparametric MRI and clinical indicators to help identify and grade clinically significant prostate cancer. The model showed promising levels of diagnostic accuracy and predictive performance.

Non‐Invasive Triage of Bladder Outlet Obstruction and Detrusor Underactivity in Men With Lower Urinary Tract Symptoms: A Narrative Review and Conceptual Framework for Depth‐Aware Multimodal Transcutaneous Testing

open access: yesNeurourology and Urodynamics, EarlyView.
ABSTRACT Introduction Differentiating bladder outlet obstruction (BOO) from detrusor underactivity (DU) remains a major unmet need in the management of lower urinary tract symptoms in men. Although pressure–flow urodynamics provide a definitive physiological classification, their invasiveness limits their widespread use.

Novel reference gene microseminoprotein‐beta based prostate cancer antigen 3 urine test: Enhanced diagnostic performance for prostate cancer and feasibility of non‐digital rectal examination urine sampling

open access: yesUroPrecision, EarlyView.
Abstract Background The diagnosis of prostate cancer (PCa) is limited by low specificity and invasiveness. This study aims to establish a highly accurate, noninvasive reverse transcription‐quantitative polymerase chain reaction (RT‐qPCR)‐based urinary prostate cancer antigen 3 (PCA3) assay system and explore the feasibility of using first‐morning urine

Mapping the lineage of prostate tissue ablation medical device predicates for focal therapy of prostate cancer approved via the FDA 510(k) clearance pathway

open access: yesSurgical Practice, EarlyView.
Abstract Objective Medical devices are reviewed by the US Food and Drug Administration (FDA) for safety and effectiveness. Class II devices can receive 510(k) clearance if they are “substantially equivalent” to an existing predicate device. This process can be repeated iteratively, leading to a lineage of predicates for newly cleared devices.
