Society Of Urologic Oncology Meeting - Repeat Prostate Biopsy - When, Where And How?
ORLANDO, FL (UroToday.com) - Dr. Presti discussed that the adequacy of the initial biopsy must be assessed. One must examine how many cores were taken on the first biopsy. If it was only 6 cores, there was a 40% chance of finding cancer on the second biopsy as compared to 24% when an extended pattern was initially performed. Prostate volume was also important: there was an inverse trend between size and detection. PSA indices are useful on repeat biopsy. Free/total PSA outperforms other indices such as PSAD-TZ or PSAD. PSA kinetics has not been shown to be too useful in detection on repeat prostate biopsy.
