About this trial
Prospective cohort study comparing robot-assisted radical prostatectomy and external beam radiotherapy +/- androgen deprivation therapy for high-risk non-metastatic prostate cancer in terms of health-related quality of life, functional outcomes, cost-effectiveness, progression-free survival and distant metastasis-free survival.
Eligibility criteria

Trial population
Patients with de novo non-metastatic high-risk prostate cancer (cT3a-bN0M0 and/or ISUP grade ≥4 and/or PSA \>20ng/ml), who have opted for treatment with RARP or EBRT +/- ADT and are diagnosed in, or are referred to one of the participating hospitals

Trial outcomes
Primary outcomes
Functional outcomes
Functional outcomes will be measured with the Expanded Prostate Cancer Index Composite Short Form (EPIC-26). The EPIC-26 consists of 5 domains: urinary incontinence, urinary irritation, bowel function, sexual function and hormonal function. Domain scores range from 0-100 (the higher the score the better the function) and the minimally clinically important difference (MCID) per domain is 6-9, 5-7, 4-6, 10-12 and 4-6, respectively.
Health-related quality of life (HRQoL)
HRQoL will be measured with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC-QLQ-C30). The questionnaire includes five functional domains (physical, role, cognitive, emotional and social), three symptom domains (fatigue, pain, nausea and vomiting) and a global health/quality of life scale. In addition, there are six separate items assessing dyspnea, insomnia, appetite loss, constipation, diarrhea, and perceived financial impact. For each domain and single item measure, a score from 0 to 100 can be calculated. For the functional domains and the global score, higher scores indicate a higher level of functioning/ better quality of life. In contrast, for the symptom domains and single item measures, a higher score represents a higher level of symptomatology.
Secondary outcomes
Cost-effectiveness
A cost-utility analysis (CUA) will be conducted from a societal and medical perspective. The societal perspective will specifically focus on the patients out of pocket costs. Utilities will be derived by means of a mapping algorithm for the EORTC QLQ-C30. The derived utility will be used to estimate a Quality adjusted life year (QALY) according to the trapezium rule. Incremental costs between EBRT combined with ADT and RARP will be related to incremental QALYs in a cost-utility ratio (ICUR).
Progression-free survival
Distant metastases-free survival
