Computed tomography of primary, persistent, and recurrent endometrial malignancy

J W Walsh, D R Goplerud

    AJR. American Journal of Roentgenology
    |December 1, 1982
    PubMed
    Summary

    Computed tomography (CT) aids in staging endometrial cancer, particularly for advanced stages. While limited in early stages, CT effectively detects extrauterine spread in persistent and recurrent tumors, guiding treatment decisions.

    Area of Science:

    • Oncology
    • Radiology
    • Gynecologic Oncology

    Background:

    • Endometrial malignancy staging is crucial for effective treatment planning.
    • Computed tomography (CT) is a key imaging modality in gynecologic oncology.
    • The role of CT in evaluating primary, persistent, and recurrent endometrial tumors requires clarification.

    Purpose of the Study:

    • To assess the accuracy of computed tomography (CT) in staging primary endometrial cancer.
    • To evaluate the utility of CT in detecting persistent or recurrent endometrial tumors.
    • To determine CT's contribution to treatment selection for endometrial malignancy.

    Main Methods:

    • Retrospective analysis of 24 patients with primary endometrial malignancy.
    • Evaluation of 12 patients with suspected persistent tumor and 29 with suspected recurrent tumor using CT.

  • Comparison of CT findings with surgical and clinical staging.

    • Main Results:

    • CT could not differentiate early-stage (IA, IB, II) primary endometrial tumors.
    • CT demonstrated significant value in identifying parametrial extension and extrapelvic metastases in advanced-stage (III) primary tumors.
    • CT accurately showed extrauterine tumor spread (86%) and tumor confined to the uterus (83%), but missed microscopic nodal or bladder involvement.
    • CT was sensitive in detecting pelvic tumor and various metastases in persistent and recurrent cases.
    • CT findings supplemented clinical assessment for treatment choices (surgery, radiation, chemotherapy).

    Conclusions:

    • Computed tomography (CT) is valuable for advanced-stage primary endometrial cancer and for detecting persistent or recurrent disease.
    • CT's limitations include differentiating early stages and detecting microscopic disease.
    • CT findings are supplemental to clinical evaluation and other diagnostic methods like cytology for vaginal recurrences.
