[When should we perform a bone scintigraphy in patients with new diagnosis of asymptomatic prostate cancer in order to detect bone metastasis?].

Objective: To define, based on PSA value, Gleason score (GS), clinical stage and age, those patients diagnosed with asymptomatic prostate cancer whose cases warrant further study of bone metastasis (BMet).

Methods: From January 2006 to May 2010, we evaluated 263 patients diagnosed with prostate cancer who were chosen for further study of bone scintigraphy following the consensus protocol accepted by the Ministry of Health of Andalusia (Integrated Andalusian Process Prostate Cancer-BPH). All selected studies met the criteria defined in the test indications: PSA >10 or Gleason score (GS) ≥7 or positive biopsy of seminal vesicles, all without symptoms of bone pain.
