What this trial studies

The Utrecht Prostate Cohort aims to create a comprehensive observational database for patients with newly diagnosed prostate cancer. This cohort will facilitate multiple randomized controlled trials to evaluate new treatment interventions while also assessing short- and long-term clinical and patient-reported outcomes. Utilizing the Trials within Cohorts (TwiCs) design, the study will allow for simultaneous evaluation of various interventions within a large prospective cohort. The participating centers include the University Medical Center Utrecht and St. Antonius Hospital Nieuwegein, both of which provide a full spectrum of prostate cancer care.

Who should consider this trial

Good fit: Ideal candidates are men aged 18 and older with newly diagnosed histologically proven prostate cancer.

Not a fit: Patients who are mentally incompetent or unable to understand the Dutch language may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options and quality of life for patients with prostate cancer.

How similar studies have performed: Other studies utilizing the TwiCs design have shown promise in evaluating treatment interventions, suggesting this approach is both innovative and tested.
