Abstract
Purposes: To address prostate cancer (PCa) detection with respect to the number of biopsy sessions performed, to identify risk factors for detection after a negative biopsy, and to analyze the clinical characteristics of the detected tumors.
Scope: Only biopsied men (sextant) were included. A total of 1011 biopsy sessions were carried out in 770 men; 172 underwent a second prostate biopsy and 51 a third biopsy. During the first biopsy round, 111 cancers were found (14.4%), 27 in the second (15.7%), and five during the third round (9.8%), P=0.156. Only high-grade PIN or atypia were identified as independent predictors or PCa detection in subsequent biopsies (P=0.008). A nonsignificant increase of clinically localized tumors, and a decrease of metastatic and poorly differentiated cases were found when more biopsy sessions were needed for detection.
Conclusions: A nonsignificant trend to lower cancer detection rates and less clinical relevance of the tumors detected can be observed when more biopsy rounds are needed for detection.
