[Prostate cancer in the Community of Madrid in the year 2000. III. Study of tumor extent].
OBJECTIVE
To identify a potential relationship between two variables, risk of metastasis and use of imaging techniques, in an extension study in prostate cancer patients diagnosed in the Autonomous Community of Madrid in 2000.


METHODS
1,127 patients with available data on the tumour extension study were analysed. Performance and non performance of bone scans and CTs were correlated to risk variables for developing metastasis as described in the literature (PSA, Gleason and stage) and to therapy administered.


RESULTS
The proportion of patients with risk variables for metastasis when bone scans were performed was between 7% to 14% greater than in patients with no variables. No differences were seen for CTs based on risk variables. With matching risk variables, more imaging techniques were used in patients receiving radiotherapy that in those managed with prostatectomy.


CONCLUSIONS
Based on current recommendations imaging techniques were used in excess in the extension study in patients with no risk variables for metastasis. Conduct of a further study in the Autonomous Community seems advisable to confirm the likelihood of implementing such recommendations considering our prevalence of metastatic disease.
