Abstract
BACKGROUND
The indication for a radionuclide bone scan in patients with newly diagnosed, untreated prostate cancer remains controversial.
PATIENTS AND METHODS
In this retrospective study we examined 406 patients who had received a staging bone scan irrespective of their PSA serum level and histology. We evaluated different guidelines and recommendations with respect to their usefulness. The costs were calculated according to EBM and GOA. We evaluated the classification systems of bone metastases according to Soloway, Crawford, and Rigaud.
RESULTS
The bone scan was positive in 41 (10%) of 406 patients. The EAU guidelines turned out to be useful with respect to both clinical value and cost efficiency. The Rigaud classification of bone metastases predicted outcome better than the Soloway or Crawford classification.
CONCLUSIONS
The EAU guidelines from 2005 are a useful tool to decide whether to perform a bone scan in patients with newly diagnosed, untreated prostate cancer. A bone scan should be performed if PSA levels exceed 20 ng/ml in patients with a G1/G2 histology, and in patients with G3 histology and locally advanced disease irrespective of PSA level. Bone scan metastases should be classified according to Rigaud.
