Prospective Prostate Cancer Infrastructure (ProPCI)

April 28, 2026 updated by: Radboud University Medical Center
The goal of this observational study is to collect detailed long-term real-world data and biomaterials from men with high-risk localized prostate cancer and synchronous metastatic hormone-sensitive prostate cancer. This will help to better understand how these patients are treated in daily practice, how treatments affect quality of life, and facilitate biomarker discovery. The infrastructure is also designed to enable future cohort multiple randomized controlled trials.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Study Population

All patients with treatment-naive high-risk localized and treatment-naive metastatic prostate carcinoma will be eligible to participate. These patients are identified by their treating physicians in all participating hospitals.
