    Area of Science:

    • Urology
    • Oncology
    • Pathology

    Background:

    • Prostate cancer diagnosis relies on accurate methods.
    • Transrectal fine needle aspiration (FNA) biopsy is a key diagnostic tool.

    Purpose of the Study:

    • To evaluate the efficacy of transrectal fine needle aspiration biopsy for diagnosing prostatic carcinoma.
    • To compare cytological findings with histological results.

    Main Methods:

    • Cytological examination of 1280 transrectal fine needle aspiration biopsies from 1122 patients over 10 years.
    • Microscopic analysis and classification of prostatic tissues.
    • Comparison of cytology results with histological examination in 469 cases.

    Main Results:

    Related Experiment Videos

  • 467 out of 1280 aspirates were diagnosed as carcinoma.
  • In cases with both cytology and histology (469), 255 prostatic carcinomas were diagnosed.
  • Cytology alone diagnosed 20% of cases, histology alone diagnosed 27%, and 53% were diagnosed by both methods.

    • Conclusions:

    • The Franzen needle biopsy technique plays a significant role in diagnosing prostate cancer.
    • Cytological examination of prostate biopsies is a valuable diagnostic method.
    • The technique demonstrates good concordance with histological findings.
