• Patients at increased risk for prostate cancer with previously negative biopsies pose a diagnostic challenge. We have previously demonstrated that extensive saturation biopsy can be performed in an office setting. We now report the diagnostic yield of office saturation biopsy in patients at increased risk for prostate cancer and at least 1 negative prior biopsy. We performed saturation prostate biopsy with local anesthesia in the office in 116 patients with at least 1 prior negative biopsy and with certain risk factors, namely persistently elevated prostate specific antigen, abnormal digital rectal examination, or prior atypia or PIN on prior biopsy. A total of 34 cancers were detected for an overall diagnostic yield of 29%. A 64% detection rate was noted when a patient had undergone a single prior sextant biopsy. Subgroup analysis revealed a cancer detection rate of 41% when only prior sextant biopsies were performed, and a 24% detection rate when 10 or more cores were taken on prior biopsy. The detection rate was 33% when only 1 prior biopsy was taken and it was 24% when 2 or more prior biopsies were performed. Saturation biopsy can be performed safely and effectively in the office with a significant diagnostic yield even in patients with previous extended biopsy schemes. We believe that it should be the next diagnostic step after an initial negative biopsy in patients in whom the diagnosis of prostate cancer is strongly suspected.
