Abstract:
Objective To investigate the accuracy of the quantity of tumors combined with vesical imaging reporting and data system(VI-RADS)score in predicting bladder cancer(BCa)muscle invasion.Methods The multiparametric magnetic resonance imaging(mpMRI)and clinical data of 91 patients with BCa confirmed by pathology were analyzed retrospectively.The differences in detection indicators between patients with muscle invasive bladder cancer(MIBC)and non-muscle invasive bladder cancer(NMIBC)were com-pared by univariate logistic regression analysis.The independent risk factors of BCa muscle invasion were screened by multivariate logis-tic regression analysis.The receiver operating characteristic(ROC)curve were plotted for the identified independent risk factors,and the area under the curve(AUC)was calculated to analyze their diagnostic efficacy.Results There were 54 cases of MIBC and 37 cases of NMIBC.The results of univariate logistic regression analysis showed that the quantity of tumors,hematuria,age,apparent diffusion coefficient(ADC),tumor contact length(TCL),and VI-RADS score were statistically significant between the two groups(P＜0.05).The results of multivariate logistic regression analysis showed that the quantity of tumors and VI-RADS score were independent risk fac-tors for MIBC.ROC curve analysis showed that VI-RADS score≥ 4 points was the best threshold for predicting BCa muscle inva-sion.The accuracy of VI-RADS score combined with the quantity of tumors in predicting BCa muscle invasion was better than that of the quantity of tumors and VI-RADS score alone,and the difference was statistically significant(P＜0.05).Conclusion VI-RADS score combined with the quantity of tumors further improves the accuracy of predicting BCa muscle invasion.
