About

Prospective research of Natural Killer cells as predictive biomarkers to stratify patients likely to have longer response time to castration.

Full description

The main objective is to validate prospectively the results of a retrospective study showing a correlation between the level of NKp30 and NKp46 receptor-activators expression on the surface of NK cells and 1) the survival time, 2) the response time to castration in patients with metastatic prostate cancer.

Prospective monocenter, open-label study.

During a visit in the frame of management of the disease, a single blood sample will be collected. Patients will then have a standard care follow-up for a period of 5 years. Follow up data (death, progression) will be collected every 6 months.
