Role of transperineal six-core prostate biopsy in patients with prostate-specific antigen level greater than 10 ng/mL and abnormal digital rectal examination findings

Six-core biopsy provided a similar cancer detection rate compared with 12-core biopsy in patients with PSA levels greater than 10 ng/mL and abnormal DRE findings. An initial approach with 6-core biopsy is reasonable in patients with a PSA level greater than 10 ng/mL and abnormal DRE findings and is advocated in those with PSA greater than 20 ng/mL and abnormal DRE findings.
