Preoperative Magnetic Resonance Imaging Modalities in Endometrial Cancer Staging: Retrospective Study
Background:
Endometrial cancer is 1 of the 3 most commonly occurring malignant tumors in the female reproductive tract.
Objective:
This study explored 3.0 T MRI (magnetic resonance imaging) for measuring the characteristics of endometrial cancer and evaluated the value of plain scans and enhanced combined diffusion-weighted imaging in preoperative staging of endometrial cancer.
Methods:
We retrospectively analyzed the clinical data of women with endometrial cancer who were admitted to the gynecology department of our hospital between January 2014 and August 2018.
Results:
Patients (N=202) with endometrial cancer underwent MRI and had the findings confirmed by surgical pathology. Preoperative MRI diagnosis showed 140 patients with stage IA, 20 with stage IB, 18 with stage II, 5 with stage IIIA, 13 with stage IIIB, 2 with stage IIIC1, 1 with stage IIIC2, 1 with stage IVA, and 2 with stage IVB. Surgical pathology confirmed 131 patients with stage IA, 28 patients with stage IB, 15 patients with stage II, 3 patients with stage IIIA, 16 patients with stage IIIB, 4 patients with stage IIIC1, 1 patient with stage IIIC2, 1 patient with IVA stage, and 3 patients with stage IVB cancer. The overall agreement between preoperative staging and postoperative pathological staging was 92.1% (186/202).
Conclusions:
The coincidence rate between 3.0 T MRI preoperative staging and postoperative pathological staging is high, and it can be used as a routine examination for patients with endometrial cancer, thus providing an objective basis for clinical decision making.
