Early detection of ovarian cancer using transvaginal sonography (TVS) shows promise. TVS identified Stage I cancers, leading to successful treatment and reduced mortality, warranting further large-scale studies.

Area of Science:

  • Gynecologic Oncology
  • Diagnostic Imaging
  • Cancer Screening

Background:

  • Ovarian cancer has a poor prognosis due to late-stage diagnosis, despite treatment advances.
  • Early detection is crucial as ovarian cancer meets criteria for effective screening.
  • Significant reduction in mortality is possible with early-stage intervention.

Purpose of the Study:

  • To evaluate the effectiveness of screening methods for early ovarian cancer detection.
  • To assess the role of transvaginal sonography (TVS) in identifying early-stage ovarian cancer.
  • To determine if TVS screening can reduce ovarian cancer mortality.

Main Methods:

  • Utilized serum CA 125 levels and transvaginal sonography (TVS) for screening.
  • Screened approximately 8000 asymptomatic women using TVS.

  • Evaluated CA 125, Doppler flow sonography, and morphology index to improve TVS specificity.

    • Main Results:

    • TVS detected 10 primary ovarian cancers, all Stage I, with successful treatment outcomes.
    • TVS screening demonstrated high sensitivity but moderate specificity.
    • TVS significantly reduced the stage at detection and case-specific death rate.

    Conclusions:

    • Transvaginal sonography (TVS) shows potential for early ovarian cancer detection.
    • TVS screening led to the detection of curable, early-stage cancers.
    • A large multiinstitutional study is needed to confirm if annual TVS screening reduces ovarian cancer mortality.
