The continuing role of fine-needle aspiration of the prostate gland into the 21st century: A tribute to Torsten Löwhagen

A brief review of the history of transrectal fine-needle aspiration (FNA) of the prostate gland is reported in this article; the authors'experience of FNA during the last 20 yr is described also. Despite the worldwide acceptance of the thin-needle core approach, the use of transrectal FNA of palpable abnormalities of the prostate still is advocated because it is cheaper, faster, easier to perform, and results in lower morbidity than any other technique so far developed. High sensitivity, specificity, and efficacy account for its reliability. Appropriate training in performing transrectal FNA of the prostate and in interpreting the smears is, of course, essential. Transrectal FNA should be the initial diagnostic procedure for suspected prostatic cancer and will continue to be a useful diagnostic tool in the 21st century.
