Brief Summary:
To determine if the use of Prostate-Specific Membrane Antigen Positron Emission Computer Tomography (PSMA PET/CT) as a selection tool for performing extended lymph node dissection (ePLND) for prostate cancer (PCa) in the primary staging setting results in fewer ePLND procedures and therefore lower overall healthcare costs, lower patient burden in terms of intervention-related complications and morbidity, with comparable disease prognosis, compared to the current European Guideline-recommended standard practice which includes performing ePLND in PCa patients who are candidates for active treatment with a nomogram-calculated lymph node involvement (LNI) risk \>5%.
Detailed Description:
Background: Use of prostate-specific membrane antigen (PSMA) positron emission tomography (PET) - computer tomography (CT) has drastically improved the ability to detect and exclude presence of pelvic lymph node invasion (LNI) compared to conventional imaging. However, current standard of care still includes performing extended pelvic lymph node dissection (ePLND) in all patients with primary prostate cancer and a nomogram-based risk of LNI \>5%. It is unclear if use of PSMA PET/CT as a triage test can safely reduce the number of ePLND and hence reduce the associated morbidity and costs, without negatively influencing disease prognosis.
Objective: To assess whether PSMA PET/CT can be safely used as a triage test for selecting primary prostate cancer patients for ePLND. We will additionally assess cost-effectiveness of the PSMA PET/ CT triage strategy.
Design, setting and Participants: THE PSMA-SELECT trial includes patients with biopsy-confirmed prostate cancer, without evidence of distant metastasis (M0) on PSMA PET/CT, opting for treatment with radical prostatectomy (RP), with a nomogram-calculated risk of LNI \>5%. Patients will be randomized 1:1. In the intervention arm patients will only undergo ePLND in addition to robot-assisted radical prostatectomy (RARP) in case of suspected LNI on PSMA PET/CT (miN1), whereas ePLND will be omitted in those without PSMA positive lymph nodes (miN0). In the control arm, all patients will undergo ePLND in addition to RARP.
Outcome measurements and statistical analysis: The primary endpoint of this study is biochemical recurrence rate at two years post-surgery. Secondary outcome measures are number of ePLNDs indicated and performed, treatment-related adverse events, initiation of salvage treatment, metastasis-free survival, patient-reported outcome measures and individual and cumulative healthcare costs.
