Correlation of Gleason Scores Between Needle-Core Biopsy and Radical Prostatectomy Specimens in Patients with Prostate Cancer

The accuracy of Gleason scores determined by needle biopsy in patients with prostate cancer seems to be unreliable. Therefore, further evaluation of patients is necessary. No correlations were noted between biopsy-measured errors in Gleason score and biopsy number, prostate volume, or preoperative serum PSA level.
