Lead Sponsor:

Centre Hospitalier Universitaire de Liege

Conditions:

Macroscopic Tumor Visualized at MRI

Phase:

PHASE2

Brief Summary

\*Rationale : Active surveillance of prostate cancer helps to avoid the morbidity associated with curative radical prostatectomy /radiotherapy in patients with early stage disease. However, at 5 years...
