Sonographic Findings of Early Prostatic Cancer: With Clinical Correlation
|
|
|
|
|
Abstract
|
|
|
We retrospectively analyzed 7 cases of transrectal ultrasonography(TRUS) of patients with early prostatic cancer(stage A & B), and correlated with clinical findings such as digital rectal examination(DRE), serum PSA, and pathologic Gleason
grade.
TRUS detected prostatic cancer in 5 of 7, PSA was elevated above normal range in 6 of 7, and hard nodules were palpated in 6 of 7.
One case of stage A adenocarcinoma of prostate was not detected sonographically due to inhomogeneous echogenecity.
One case of stage B adenocarcinoma of prostate was not detected due to its isoechogenecity.
Five cases stage B adenocarcinoma were located at the peripheral zone and showed hypoechoic lesions in TRUS.
We conclude that TRUS is useful in detection of early prostatic cancer when combined with serum PSA and DRE.
