Radical Prostatectomy

To learn about the safety and effects of a drug called REGN5678 when it is given to patients with high-risk prostate cancer.

The objective of this study is to compare safety and effectiveness of the Voro Urologic Scaffold in adult men undergoing robotic assisted radical prostatectomy as compared to control arm. The study is a multi-center, single blind, randomized, controlled trial. Up to 266 participants will be treated at up to 30 centers in the United States. The study will consist of a Baseline visit, implantation during robotic assisted radical prostatectomy (RARP), catheter removal, 6 weeks, 6 months, 12 months, 18 months, and 24 months.

Prostate cancer is the most common cancer amongst men in the United Kingdom, and two common curative treatments are surgery to remove the prostate (radical prostatectomy) or radiotherapy. Both treatments can affect quality of life, mainly because of problems with erections and urinary leakage. Many men feel disappointed or regret their treatment choice because of changes in their sexual function. Surgeons often use a 'nerve-sparing' technique to reduce the risk of erectile dysfunction (ED), but many men still experience erection problems afterwards. A way to improve erectile function recovery after surgery further would be to identify accessory (additional) arteries to the penis. Up to one in three men have an extra artery called the accessory pudendal artery (APA). Preserving this artery during surgery may improve recovery of erections by protecting blood flow and reducing the risk or severity of ED. Until recently, surgeons could only try to see these arteries during the operation, and no study has tested whether they are preserved or whether this makes a difference. This has changed with the advent of imaging. Men already have an advanced MRI scan (called a multiparametric MRI) before prostate cancer treatment. These scans can also show whether an APA is present. In addition, robotic surgery, now the gold standard for radical prostatectomy, allows operations to be video recorded. This allows comparison of what was seen on the scan with what happened during surgery and then monitoring of recovery afterwards. Early research suggests that men with an APA have better erections before surgery. This study will test whether preserving the APA during surgery helps erections recover afterwards. In this first phase of the research (Phase 1), a feasibility study will be carried out at University College London Hospital. The study will invite 20-40 men with good sexual function before surgery, who are having robotic prostatectomy with a nerve-sparing approach. Multiparametric MRI scans will be used to identify whether an APA is present and video recordings will be collected to see if the artery was preserved. Participants will complete simple questionnaires on erections and quality of life before and after surgery up to 1 year. To assess whether the artery was preserved, an extra MRI scan will be organised after surgery for those with an APA, as well as penile ultrasound to assess erectile machinery. Ethical approval has already been obtained from the regulatory bodies, and the study is ready to start recruiting participants. The results will allow planning of a larger, national study (Phase 2). That study will test whether preserving the APA improves erectile recovery, reduces the severity of ED, and improves quality of life. If confirmed, this research could lead to modification in surgical approach, more personalised counselling before surgery, and reduced long-term need for costly ED treatments within the NHS.

This prospective observational study aims to evaluate the prognostic significance of early postoperative prostate-specific antigen (PSA) levels in patients undergoing radical prostatectomy for prostate cancer. No investigational interventions will be performed. All diagnostic procedures, follow-up assessments, and treatments will be conducted in accordance with standard clinical practice and established prostate cancer management guidelines. Participation in the study will not influence treatment decisions.

Urinary incontinence is a common complication following radical prostatectomy and can significantly impact quality of life. Pelvic floor physiotherapy is recommended to reduce post-operative incontinence; however, referral pathways and patient engagement vary. The PRO-ACT trial is a single-centre, parallel-group randomised controlled trial evaluating whether a structured pre-operative education bundle combined with direct physiotherapy referral reduces urinary incontinence following radical prostatectomy compared to standard care. Eligible men undergoing radical prostatectomy at Beaumont Hospital will be randomised 1:1 to either: Standard of care (educational video and recommendation for physiotherapy with patient-initiated referral), or A structured pre-operative intervention including a one-to-one ANP-led education session, scheduled post-operative follow-up call, and direct referral to supervised pelvic floor physiotherapy. The primary outcome is mean urinary pad usage per 24 hours at 3 months post-operatively. Secondary outcomes include time to continence, quality of life, physiotherapy adherence, and postoperative complication rates.
