Feasibility Study of Urinary cfDNA Analysis as a Non-invasive Monitoring Tool in Patients With Prostate or Bladder Cancer (UroDNA)

March 12, 2026 updated by: Institut Cancerologie de l'Ouest

Feasibility Study of Circulating Tumour DNA Analysis in Urine (Urinary cfDNA) as a Non-invasive Monitoring Tool in Patients With Prostate or Bladder Cancer

The UroDNA study is a feasibility study (RIPH category 3) aimed at evaluating the analysis of circulating tumour DNA in urine (urinary cfDNA) as a non-invasive monitoring tool in patients with prostate or bladder cancer. Urine samples will be collected at different times during the course of treatment to define the optimal conditions for cfDNA collection, extraction and analysis, and to explore the detection of tumour mutation profiles. This study does not involve any experimental treatment. Its objective is to validate the technical and clinical feasibility of a molecular monitoring urine test, which could offer a simple and non-invasive alternative to improve the management of urological cancers.
