Using PSMA PET/CT to guide surgery for prostate cancer

Preoperative PSMA PET/CT As Triage for Extended Pelvic Lymph Node Dissection (ePLND) in Patients Scheduled for Robot-Assisted Laparoscopic Radical Prostatectomy (RALP)

Not applicable Interventional Oslo University Hospital · NCT06398613

This study is testing if a special imaging scan can help guide surgery for prostate cancer patients instead of a more invasive procedure, to see if it leads to better outcomes after treatment.

What this trial studies

This study aims to evaluate whether preoperative prostate specific membrane antigen (PSMA) PET/CT can replace extended pelvic lymph node dissection (ePLND) as a staging method for prostate cancer patients undergoing robot-assisted laparoscopic radical prostatectomy (RALP). Eligible patients will undergo PSMA PET/CT and will be randomized into two groups: one receiving RALP with ePLND if suspicious nodes are detected, and the other receiving only RALP if no suspicious nodes are found. The primary outcome is to compare the biochemical recurrence rates between the two groups within two years post-treatment.

Who should consider this trial

Good fit: Ideal candidates include men with biopsy-proven prostate adenocarcinoma who are classified as high-risk and require ePLND combined with RALP.

Not a fit: Patients with a history of previously treated prostate cancer or those with distant metastasis will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could reduce the need for invasive surgeries while maintaining effective cancer staging.

How similar studies have performed: Other studies have shown promising results using PSMA PET/CT for staging prostate cancer, indicating potential success for this approach.
