[Type and extent of preoperative imaging before radical prostatectomy].
BACKGROUND
According to current guidelines, in cases of newly diagnosed prostate cancer the type and extent of imaging to be performed should be based on the patient's risk profile. We investigated the rate of computed tomography (CT), magnetic resonance imaging (MRI), and bone scintigraphy carried out before radical prostatectomy (RP) depending on the individual risk profile.


METHODS
Between 1 January 2006 and 31 December 2007, a total of 1,018 consecutive patients who had not received neoadjuvant hormone therapy were treated with RP in our department. We determined the preoperative rates of CT, MRI, and bone scintigraphy by reviewing the medical charts. The patients were stratified according to the D'Amico criteria into low-risk, intermediate-risk, and high-risk groups.


RESULTS
Of the 1,018 subjects, 493 (48%) were classified as low-risk, 403 (40%) as intermediate-risk, and 122 (12%) as high-risk patients, respectively. The rate of preoperative abdominal CT/MRI and bone scintigraphy was 17 and 23% in the low-risk group, 25 and 39% in the intermediate-risk patients, and 39 and 57% in the high-risk group.


CONCLUSIONS
The rate of preoperative CT and bone scintigraphy is extremely high in the low-risk group. In contrast the rate in the high-risk patients more likely appears to be too low. The discrepancy between the rates of preoperative imaging subject to the patient's risk profile shows that precisely formulated guidelines addressing this issue are needed.
