[US guided biopsy in the early diagnosis of prostatic cancer. A series of 66 cases].
OBJECTIVE
Our study's aim is to evaluate the reliability of digital rectal examination and serum PSA in the indication of prostatic biopsy.


METHODS
66 patients with abnormal digital rectal examination and arised PSA levels had prostatic biopsies. The sextant technique was practiced.


RESULTS
The digital rectal examination had a sensitivity of 65%, a specificity of 45% and a positive predictive value (PPV) of 34.3%. The serum PSA had a PPV of 25%. The association if these two parameters arised the PPV to 39.5%. Cancer detection rate was estimated to 30.3%.


CONCLUSIONS
Prostatic biopsies should be indicated according to the result of digital rectal examination and serum PSA.
