Comparative Study of Diagnostic and Prognosis Biomarkers of Prostate Cancer in Liquid Biopsy (HOPE)

Comparative Study of Diagnostic and Prognosis Biomarkers of Prostate Cancer in Liquid Biopsy

Constitution of a biological collection within the framework of the establishment of a diagnostic, prognostic and active surveillance test for prostate cancer from long non-coding RNA biomarkers, in 3 cohorts of patients, with cancer of the prostate, with suspected cancer without biopsy confirmation or with prostatic hyperplasia and healthy donors.

This biological collection will also be used as a support for further researches on the identification of biomarkers and genetic markers to improve the prognosis and diagnostic management of patients with prostate pathologies.

Multicenter, RIPH 2 study, evaluating on 3 patient cohorts the feasibility of setting up a diagnostic test, prognosis and active surveillance of prostate cancer using long non-coding RNA biomarkers.

For patients agreeing to participate in the study and having signed a consent form, during their routine care consultation in the urology department, will have a blood sample and a urine sample after prostate massage as part of the study, and if necessary, a tissue sample as part of the treatment.

Patients with prostate cancer will be followed as part of their care at least annually, and their follow-up data will be collected as part of the study, without additional sampling.

A blood sample and a urine sample after prostate massage will be carried out during a single consultation at the CIC Henri Mondor for
