A ccuracy of preoperative magnetic resonance imaging in assessing lymph node metastasis and myometrial invasion in patients with uterine cancer
†These authors contributed equally.
Objectives: Our aim was to know preoperative magnetic resonance imaging (MRI) can accurately predict lymph node metastasis (LNM) and deep myometrial invasion (DMI，≥50%） in patients withuterine cancer. Methods: From January 1997 to December 2006, 99 patients who were diagnosed with uterine cancer and surgically staged at our institution were retrospectively analyzed. Preoperative clinicopathologic characteristics and MRI findings were reviewed and compared with LNM status and DMI observed in the final pathology. Results: The sensitivity, specificity, positive predictive value (PPV), and negative predictive values (NPV) for MRI in determination of pelvic LNM were 77.7%, 85.6%, 35.0%, and 94. 7%, respectively. MRI failed to detect the presence of paraaortic LNM in all of the three patients with positive paraaortic lymph nodes. The sensitivity, specificity, PPV, and NPV for MRI in determining DMI were 46. 6%, 84.5%, 35%, and 89.8%, respectively. Conclusion: Preoperative evaluation of uterine cancer by MRI does not accurately predict the LNM and DMI.
