  • Title: Transrectal aspiration biopsy of the prostate: the importance of atypia.
    Author: Smith FL, Bibbo M, Schoenberg HW, Chodak GW.
    Journal: J Urol; 1988 Oct; 140(4):766-8. PubMed ID: 3418797.
    Abstract:
    Transrectal aspiration biopsy is useful as an alternative method to examine the prostate. As a means to improve the sensitivity of this method we investigated the significance of cellular atypia. Transrectal aspiration biopsy revealed highly atypical cells in 30 of 225 patients and in 17 patients slightly atypical cells were found. Biopsy was repeated in 22 patients with highly atypical cells and cancer was confirmed in 17 (77 per cent). In the group with only slight atypia 2 of 6 patients had cancer upon repeat prostatic biopsy. When transrectal aspiration biopsy contains highly atypical cells biopsy should be repeated to avoid a false negative diagnosis. These results suggest that atypia is an abnormal finding that must be followed clearly to maintain a high sensitivity with this biopsy method.
