Eligibility
Inclusion criteria
Inclusion criteria: Cohort A: Patients with hormone-sensitive prostate cancer scheduled for radical prostatectomy with pelvic lymph node dissection, 2) in the pelvis. Cohort B: Patients with hormone-sensitive recurrent prostate cancer after radical prostatectomy with planned pelvic salvage lymph node dissection, 2) in the pelvis, PSA value <2ng/ml.
Exclusion criteria
Exclusion criteria: Estimated life expectancy <10 years, contraindication for surgical intervention, androgen deprivation therapy (ADT) within the last 3 months
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the detection rate of lymph node metastases using PSMA-targeted surgery with or without a virtual 3D model (the preoperative PSMA PET scan). The 3D model is used for surgical guidance during open/robotic primary prostatectomy with pelvic lymph node dissection (Cohort A) or open/robotic salvage lymph node dissection (SLND) for recurrent prostate cancer (Cohort B). The postoperative histology of the specifically dissected tissue serves as a reference. | — |
Secondary
| Measure | Time frame |
|---|---|
| Feasibility and accuracy of preoperative virtual 3D modeling for patient consultation and surgical planning (determined by pre- and postoperative standardized User Experience Questionnaire (UEQ) and Mixed reality Questionnaire). Retrospective analysis of vision-based and robotic tracking methods for target detection and retrospective analysis of the efficiency of PSMA-targeted dissection based on instrument tracking information (in robotic surgery). Diagnostic accuracy of PSMA-PET-CT for detection of lymph node metastases during open/robotic primary prostatectomy with pelvic lymph node dissection (Cohort A) or open/robotic salvage lymph node dissection (SLND) for recurrent prostate cancer (Cohort B) with post-operative histology of all dissected specimens as reference. Short-term oncologic outcomes (complete biochemical response (cBR), defined as a PSA level <0.2 ng/mL at 8-12 weeks (Cohort A) or 4-6 weeks (Cohort B)). Quality of life (SF-12, EPIC-26), morbidity (intra- and postoperative complications within 6 months according to the Clavien-Dindo classification) and satisfaction (Decision Regret Scale) after PSMA-targeted surgery for primary prostatectomy and pelvic lymph node dissection (cohort A) or after salvage lymph node dissection (cohort B) with/without preoperative guidance of the virtual 3D model. | — |
