Evaluation of Sodium Fluoride PET in the Identification of Bone Metastases in Patients Having Undergone a Choline PET for Occult Recurrence of Prostatic Adenocarcinoma

Not Applicable
Conditions
Bone Metastasis
Interventions
Procedure: Sodium fluoride PET
Registration Number
NCT02876991
Lead Sponsor
Central Hospital, Nancy, France
Brief Summary

The purpose is to evaluate if sodium fluoride PET in patients having already undergone a choline PET negative for bone extension (non-metastatic status) modifies the status of patients concerning the existence or not of bone metastases.

Secondary purposes are:

* To evaluate if detection of bone metastasis by sodium fluoride PET, not detected by choline PET, leads to change of treatment

* To evaluate inter-technique concordance (choline vs sodium fluoride PET) of results (metastatic status and number of lesions)

* To evaluate the inter-judge concordance of interpretation of sodium fluoride PET

* To study the discordance of metastatic status of 2 techniques.
