Laparoscopic vs Robotic-Assisted Radical Prostatectomy

Not Applicable
Completed
Conditions
Prostate Cancer
Interventions
Procedure: Prostatectomy
Registration Number
NCT03682146
Lead Sponsor
University of Leipzig
Brief Summary

This randomized trial was designed to address the lack of high-quality literature comparing robotic-assisted (RARP) and laparoscopic (LRP) radical prostatectomy (RP).

Purpose: The LAP-01 trial compares outcomes between RARP and LRP.

Detailed Description

LAP-01 is the first multicenter, prospective randomized, patient-blinded controlled trial comparing robotic-assisted and conventional laparoscopic radical prostatectomy.

The investigation include an extensive evaluation of clinical, oncological, functional and quality of life related data by means of validated patient-reported outcome measures.

The primary outcome is the assessment of time to continence restoration at 3 months. This is evaluated by an assessment of a pad diary completed daily by each patient from the time of catheter removal until restoration of continence. Secondary endpoints include continence and erectile function, as well as quality of life (EORTC-QLQ-C30, EORTC-QLQ-PR25), patient satisfaction and Hospital Anxiety and Depression Scale (HADS) at 1, 3, 6 and 12 months after surgery in addition to oncological outcomes up to 3 years follow-up.

With 782 enrolled patients it is the largest trial carried out till date on this topic.

Tumor Resection

Prostate-specific quality of life of patients1, 3, 6, 12 months postoperative

Prostate-specific quality of life questionnaire (EORTC QLQ-PR25). Raw scores are linearly transformed into a 0-100 point scale. High functioning scores indicate good QoL, whereas elevated symptom scores represent a high level of symptomology and therefore impaired QoL.

Anxiety and depression assessment1, 3, 6, 12 months postoperative

The Hospital Anxiety and Depression Scales (HADS-D)

Further anti-cancer therapy

Continence1, 3, 6, 12 months postoperative

Continence (ICIQ-SF scores)

Erectile function1, 3, 6, 12 months postoperative

Erectile function questionnaire (including IIEF-5 questionnaire) and information on supportive medication for erection

Health-related quality of life of patients1, 3, 6, 12 months postoperative

Health-related quality of life questionnaire (EORTC QLQ-C30). Raw scores are linearly transformed into a 0-100 point scale. High global health status and functioning scores indicate good QoL, whereas elevated symptom scores represent a high level of symptomology and therefore impaired QoL.

Patient satisfaction1, 3, 6, 12 months postoperative

Patient satisfaction is measured on a 5-point scale ranging from highly dissatisfied to highly satisfied. Additionally, patients are asked if they would in hindsight make a decision for or against the surgery and if they would advise a friend to undergo surgery under the same circumstances.

Rate of relapse and metastases1, 3, 6, 12, 24, 36 months postoperative

Relapse and metastases
