Abstract:
The study is to explore the diagnostic value of magnetic resonance imaging (MRI) for endometrial carcinoma. Clinical data of 199 patients with endometrial cancer confirmed by diagnostic uterine curettage in the Second Hospital of Jilin University and the People′s Hospital of Xinjiang Uygur Autonomous Region from June 2017 to December 2019 were reviewed retrospectively. The data were analyzed by SPSS 21.0 software. MRI scan was performed before operation, the diagnostic accuracy of MRI for the preoperative staging of endometrial carcinoma was 85.9%(171/199) with postoperative pathological results as gold standard. The Kappa values of muscular infiltration, cervical infiltration and lymph node metastasis were 0.353, 0.574 and 0.573, respectively ( P<0.05). The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for myometrial invasion on MRI were 45.2%(19/42), 88.5%(139/157), 51.4%(19/37), 85.8%(139/162) and 79.4%(158/199), respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for cervical invasion on MRI were 58.3% (14/24), 96.0%(168/175), 66.7% (14/21), 94.4%(168/178)and 91.5%(182/199), respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy for lymph node metastasis on MRI were 12/18, 95.6%(173/181), 60.0%(12/20), 96.6%(173/179)and 93.0%(185/199), respectively. The results indicate that MRI has high accuracy and negative predictive rate in evaluation of preoperative staging of endometrial cancer.
