OBJECTIVE: To assess the value of magnetic resonance imaging (MRI) to identify endometrial cancer patients at risk of lymph node metastasis.
METHODS: Retrospective review of data from 108 patients with clinical stage I endometrial cancer who underwent preoperative MRI and were treated surgically. Patients at risk of lymph node metastasis were defined as those who had more than 50% myometrial infiltration or cervical invasion. Preoperative MRI reports were compared with final pathologic results.
RESULTS: The mean age of the patients was 69.5 years and most patients had endometrioid cancer. On final pathologic analysis, 59 patients had deep myometrial infiltration or cervical invasion. For diagnosis of deep myometrial infiltration, cervical invasion, or both, MRI sensitivity and specificity were 56% and 85%; 47% and 83%; and 67% and 77%, respectively.
CONCLUSION: MRI has limited value in identifying patients with endometrial cancer who are at risk of lymph node metastasis. Minimally invasive laparoscopic lymph node staging should be undertaken when it is feasible.
