INTRODUCTION: The diagnostic and therapeutic landscape for high-risk localised prostate cancer and synchronous metastatic hormone-sensitive prostate cancer (mHSPC) is rapidly evolving, driven by advances in imaging, risk stratification and systemic therapies, including the advent of precision medicine. High-quality real-world data integrating clinical, imaging, molecular, quality-of-life information and outcome data remain scarce. The PROspective Prostate Cancer Infrastructure (ProPCI) is a nationwide, multicentre observational cohort designed to collect comprehensive longitudinal data and biomaterials to support real-world evidence generation, facilitate biomarker discovery and enable future cohort multiple randomised controlled trials (cmRCTs).
METHODS AND ANALYSIS: ProPCI includes adult men with high-risk localised prostate cancer or synchronous mHSPC across hospitals in the Netherlands. Clinical data are extracted from electronic health records using a standardised protocol and linked to national registries and healthcare use datasets. Patient-reported outcome measures are collected at baseline and regular intervals using validated instruments. Serial blood samples are biobanked for circulating tumour DNA and other molecular analyses. Outcomes include diagnostic and treatment patterns, Prostate-specific antigen kinetics, time to castration-resistant prostate cancer, radiological and clinical progression, health-related quality of life trajectories and healthcare use, including expenditure and exploratory biomarker associations. Statistical methods include descriptive analyses, time-to-event models, mixed-effects models and biomarker-outcome correlates.
ETHICS AND DISSEMINATION: Ethical approval has been obtained from the Committee on Research Involving Human Subjects (CMO) of Radboudumc. Written informed consent will be obtained from every participating patient and covers: (1) extraction and linkage of clinical, imaging, pathology and registry data, (2) future contact for potential cmRCT participation; and optional components (3) quality-of-life questionnaires, (4) collection of additional blood samples and (5) use of biomaterials for genomic testing. Results will be disseminated through peer-reviewed publications.
TRIAL REGISTRATION NUMBER: NCT07560748.
