In stage IIB, cancer (1) is found in both lobes of the prostate; the PSA can be any level and the Gleason score can range from 2 to 10; or (2) cannot be felt during a digital rectal exam and is not visible by imaging, and the tumor has not spread outside the prostate; the PSA level is 20 or higher and the Gleason score can range from 2 to 10; or (3) cannot be felt during a digital rectal exam and is not visible by imaging, and the tumor has not spread outside the prostate; the PSA can be any level and the Gleason score is 8 or higher.
