ABSTRACT
PURPOSE:
Atypical small acinar proliferation (ASAP) denotes the presence of suspicious glands with insufficient cytological architecture for a definitive prostate cancer diagnosis. We evaluated the subsequent prostate cancer detection rate of rebiopsy in patients with an initial diagnosis of ASAP. MATERIALS ANDMETHODS:
Between January 2003 and December 2006, 1,416 men with suspected prostate cancer underwent a transrectal ultrasound-guided prostate biopsy, and 214 (15.1%) were diagnosed as having ASAP. Ninety-five of the 215 patients underwent at least one more biopsy. We evaluated the cancer detection rates after rebiopsy.RESULTS:
In men with ASAP, 36 patients (37.9%) had prostate cancer. The cancer detection rates of the 1st, 2nd, and 3rd rebiopsies were 30.5%, 23.8%, and 40%, respectively. Mean patient age and prostate-specific antigen did not differ significantly between the prostate cancer and noncancer groups after rebiopsy. Prostate volume, however, was significantly smaller in the cancer group (p<0.05).CONCLUSIONS:
Our results showed a detection rate for prostate cancer of 37.9% after an initial diagnosis of ASAP, which indicates that an initial diagnosis of ASAP mandates rebiopsy.
