| PURPOSE : To evaluate the relationship between hypervascularity on color/power Doppler transrectal ultrasonography
and the Gleason score of corresponding biopsied specimen in patients with prostatic cancer.
MATERIALS and METHODS : From July 1998 to March 2002, one hundred fifty seven patients with pathologically
proven prostate cancer at this institution were included, and all of them underwent transrectal ultrasonographic
examination. Initially, ultrasonographic findings and pathologic data of 129 patients were retrospectively reviewed
and excluded 28 patients whose sonographic images were either unavailable or inconclusive. The presence
of hypoechoic lesion on transrectal sonography and hypervascularity on color/power Doppler sonography
in the peripheral zone of the prostate was first evaluated, and these sonographic findings and Gleason score of
the corresponding biopsied specimen were then compared. Statistical analysis was done by Student t-test using
SPSS package.
RESULTS : Among one hundred twenty nine patients, ninety four patients had a hypoechoic lesion on gray scale
sonography while sixty one showed a hypervascular lesion on color/power Doppler sonography. Fifty seven of
61 patients (93.4%) had hypoechoic lesioin on gray scale sonography. The mean Gleason score of patients with
hypervascular lesion was 7.9±0.98 whereas that of the patients without hypervascular lesion, 6.9±1.22, showing
a statistically significant difference (p<0.01).
CONCLUSION : Prostate cancer with hypervascularity on transrectal sonography appears to have a higher Gleason score
on pathologic examination than that without hypervascularity. |
