    Abstract:

    Objective:To determine the optimal preoperative magnetic resonance imaging(MRI)radiomics parameters and compare the values in predicting disease-free survival(DFS)of early-stage cervical cancer patients with clinicopathological factors. Methods:A total of 186 patients with early-stage cervical cancers(preoperative FIGO stage ⅠB-ⅡA),who underwent radical hysterectomy with lymphadenectomy during January 2013 and June 2018,were retrospectively reviewed. Multi-sequence MR data,clinicopathologic data, and DFS data were collected;least - absolute shrinkage and selection operator(LASSO)and the Cox proportional hazard regression model were applied to construct a Rad - score. Clinicopathological models(with significant clinicopathological features),radiomics models(Rad-scores for T1CE,DWI,T2WI,T1CE+DWI,T1CE+T2WI,DWI+T2WI,and T1CE+DWI+T2WI),and combined models (the Rad - score model combined with significant clinicopathological features)were compared using a multivariable Cox model. Results:The T1CE radiomics model was the most stable and optimal model(C-index for training,0.798;for validation,0.758)of all the radiomics models. The radiomics model of T1CE showed higher prognostic performance than the clinicopathological model(C-index for training,0.746;for validation,0.641). The combined model(histological type of adenocarcinoma,lymph-node metastasis together with Rad-score for T1CE)showed the highest prognostic performance in estimating DFS(C-index for training,0.848;for validation,0.784). Conclusion:An MRI-derived Rad-score of T1CE combined with a clinicopathological model is optimal in predicting DFS in early-stage cervical cancers.
