Abstract
Objective:To explore the application of DWI combined with dynamic contrast-enhanced MRI in FIGO 2018 staging for cervical cancer.Methods:The data of 68 patients with cervical cancer were retrospectively analyzed.They all underwent DWI and dynamic contrast-enhanced MRI.The consistency between DWI combined with dynamic contrast-enhanced scan diagnosis and FIGO 2018 staging was analyzed.Results:Among the 68 patients,20 cases were FIGO 2018 stage ⅠB1,15 were stage ⅠB2,4 were stage ⅠB3,11 were stage ⅡA1,7 were stage ⅡA2,2 were stage ⅡB,2 were stage ⅢB,2 were stage ⅢC1,and 5 were stage ⅣA.DWI combined with dynamic contrast-enhanced scan were consistent with FIGO 2018 staging in 55 cases,18 cases of stage ⅠB1,13 of stage ⅠB2,2 of stage ⅠB3,9 of stage ⅡA1,5 of stage ⅡA2,2 of stage ⅡB,1 of stage ⅢB,1 of stage ⅢC1 and 4 of stage ⅣA.And Kappa consistency test showed a good consistency between the two diagnostic methods(K=0.768,P＜0.05).The Youden indices of DWI combined with dynamic contrast-enhanced scan in the diagnosis of cervical cancer at stages ⅠB1,ⅠB2,ⅠB3,ⅡA1,ⅡA2,ⅡB,ⅢB,ⅢC1 and ⅣA were 0.879,0.848,0.469,0.801,0.665,0.985,0.470,0.485 and 0.784,respectively,and the accuracies were 95.59%,95.59%,94.12%,95.59%,92.65%,98.53%,95.59%,97.06%and 97.06%,respectively.Conclusions:DWI combined with dynamic contrast-enhanced MRI has a consistency with FIGO 2018 staging in diagnosis of cervical cancer,and has a high diagnostic accuracy.关键词
