Review Comparative StudyComparison of digital rectal examination and biopsy results with the radical prostatectomy specimen.
Digital rectal examination is integral to staging prostate cancer. Ultrasound guided biopsy establishes the diagnosis, and it may provide useful information regarding disease grade and extent. Treatment decisions are largely based on information gained from digital rectal examination and biopsy but this information is only useful if it correlates with the radical prostatectomy specimen and prognosis. We correlated digital rectal examination and transrectal ultrasound guided biopsy results with a detailed analysis of the radical prostatectomy specimen. ⋯ Digital rectal examination and the interpretation of prostate biopsy are not accurate clinical tools for defining the location and extent of prostatic carcinoma. Bilateral positive biopsy may be useful as an adjunct to the current clinical staging system.
