[Abstract] Objective To access the value of multimodal MRI combined with clinical indexes to predict the efficacy of neoadjuvant therapy for stage ⅠB1-ⅡA2 cervical cancer.Materials and Methods Sixty-four cases of cervical cancer patient who received neoadjuvant therapy were retrospectively analyzed. According to the treatment response, the patients were divided into significant response group and non-significant response group. The clinical indexes, ADC value and DCE-MRI parameters (Ktrans, Kep, Ve) of the two groups were analyzed and compared. The correlation between clinical and imaging indexes of the two groups and the neoadjuvant therapy effect was analyzed to establish a reliable model for predicting treatment effect.Results Univariate analysis showed that there was no significant difference in age, tumor diameter, clinical stage [International Federation of Gynecology and Obstetrics (FIGO) 2009], squamous carcinoma antigen, pathological type. and neoadjuvant therapy methods between the two groups (P=0.092, 0.500, 0.299, 1.000, 0.101, 0.092), and there was no significant difference in ADC and Ve values between the two groups before treatment (P=0.830, 0.891, 0.853, 0.883, 0.859, 0.170, 0.159, 0.637, 0.404, 0.934). Ktrans and Kep before treatment in the significant response group were higher than those in the non-significant response group (P=0.001, 0.037). Multivariate analysis showed that the predictive model constructed by age, pathological type and the 50th percentile of Kep had the highest diagnostic efficiency, with an AUC of 0.891 (0.812, 0.971), a specificity of 86.3% and a sensitivity of 91.3%.Conclusions MRI parameters combined with clinical indexes have a certain value in predicting short-term efficacy of neoadjuvant therapy for cervical cancer.
