To investigate the association of color signal detected within prostate cancer and its biologic behavior as assessed by Gleason score. Transrectal sonography with a 7 MHz probe (Acuson, Mountain View, CA) capable of color Doppler imaging was performed in 2718 men (ages 47-72 y) and recorded on videotape for off-line review. Color signal (CDI) detected was grade 0-2+ and compared to the Gleason score (GS) graded ≤4, 5-6 and ≥7 in clinically localized prostate cancer treated by radical prostatectomy in 47. CDI signal detected within cancer was graded 2+ in 60% (17 of 28) of ≥7 tumors, 29% (12 of 42) of 5-6 tumors and 0% (0 of 9) of ≤4 tumors. The grade of color signal may provide a means of distinguishing high grade tumors from low grade tumors.
