    Transrectal ultrasonotomography effectively screens for prostate cancer (PC) and benign prostatic hypertrophy (BPH) in men over 55. This method offers a positive cost-benefit balance for early PC detection, improving patient outcomes.

    Area of Science:

    • Urology
    • Medical Imaging
    • Public Health

    Context:

    • Transrectal ultrasonotomography developed in 1967.
    • Mass screening program for prostatic diseases initiated in 1975.
    • Mobile screening unit 'Dolphin' developed in 1980.

    Purpose:

    • Evaluate the efficacy of transrectal ultrasonotomography for mass screening of prostatic diseases.
    • Assess the diagnostic accuracy of transrectal ultrasonotomography compared to digital examination for prostate cancer.
    • Analyze the cost-benefit balance of the mass screening program.

    Summary:

    • A 1983 study screened 2394 males over 55, detecting 12 cases (0.5%) of prostate cancer (PC) and 755 cases (31.5%) of benign prostatic hypertrophy (BPH).
    • Transrectal ultrasonotomography demonstrated high sensitivity (96.5%) and specificity (84.6%) for PC, outperforming digital examination (80.7% sensitivity).

  • The cost-benefit analysis indicated a positive financial return for early PC detection through mass screening.

    • Impact:

    • Transrectal ultrasonotomography proves effective for accurate and cost-efficient mass screening of prostatic diseases.
    • Early detection of PC via this method yields significant cost savings and improved patient survival.
    • The study supports the implementation of national political measures for widespread prostatic disease screening.
