Summary

Computed tomography (CT) scans are not recommended for routine preoperative staging or asymptomatic surveillance in endometrial cancer patients. Postoperative CT may aid in detecting recurrence but does not improve survival.

Area of Science:

  • Oncology
  • Radiology
  • Gynecologic Oncology

Background:

  • Endometrial cancer management relies on accurate staging and surveillance.
  • Computed tomography (CT) is a common imaging modality used in cancer care.

Purpose of the Study:

  • To evaluate the diagnostic value of CT scans for detecting extrauterine-nodal disease preoperatively.
  • To assess the utility of CT scans for identifying recurrent disease postoperatively in endometrial cancer patients.

Main Methods:

  • Retrospective review of 702 women with primary endometrial carcinoma diagnosed between 1979 and 1993.
  • Comparison of preoperative CT findings with pathological results for nodal disease assessment.
  • Analysis of postoperative CT scan yields in routine and clinically suspicious settings.

Main Results:

  • Preoperative CT had low sensitivity (57%) and positive predictive value (50%) for nodal involvement, rarely altering treatment (8%).
  • Routine postoperative CT in asymptomatic patients detected recurrence in only 4.4%.
  • CT scans for suspected recurrence confirmed it in 46% of cases, but no survival advantage was observed for CT-detected subclinical recurrences.

Conclusions:

  • Routine preoperative CT is of limited value for staging endometrial cancer and predicting nodal disease.
  • Postoperative CT may assist in recurrence detection and follow-up, but routine use is not supported by survival data.
  • CT scans for endometrial cancer should be reserved for symptomatic evaluation rather than routine staging or surveillance.
